Should I Use Screw-Retained or Cement-Retained for Dental Implant Restorations?

Implant-supported restorations require either a screw-retained or cement-retained retention method to secure the restoration to the abutment. Even though there is still controversy over which method is best, Shadid and Sadaqa reports there are advantages and disadvantages of each method of retention from different aspects. These different aspects include, “ease of fabrication and cost, esthetics, access, occlusion, retention, incidence of loss of retention, retrievability, clinical prosthesis fit, restriction of implant position, effect on peri-implant tissue health, provisionalization, immediate loading, impression procedures, porcelain fracture, and clinical performance”¹. The literature review also demonstrates there are certain clinical situations that prefer one method of retention over the other. The following will describe the different aspects that affect which method of retention is preferred over the other.

Ease of fabrication and cost

When it comes to cost, cement-retained restorations are usually the least expensive and easier to fabricate because of conventional laboratory and clinical prosthodontics techniques. Also, screw-retained restorations have extra components needed such as “plastic sleeves, laboratory fixation screws, and the fixation screws themselves”¹. However, the cost of retrievability needs to be considered when factoring in potential costs of damaging the cemented restorations if biologic or technical complications occur.

Esthetics

There have been debates on whether screw-retained restorations should be placed in an esthetic area, but with pre-angled and custom abutments the screw access channel can be changed from facial access to lingual access. When the dental implant is placed in the optimal position, predictable esthetics can be achieved with either screw- or cement-retained restorations¹.

Access

The authors argue cement-retained restorations rather than screw-retained offer easier access to the posterior of the mouth, but with new techniques it is now easier to place screw-retained restorations in the posterior of the mouth. Now with the angulated screw channel by Nobel Biocare, clinicians can easily retrieve posterior abutments with a low vertical clearance. With this angled ability, clinicians are able to change the direction of the esthetic outcome in an anterior tooth up to 25 degrees. This new technique means dental labs will be able to provide more restorative, esthetic options for clinicians.

Occlusion

Optimal and stable occlusal contacts can be found with cement-retained restorations because there are no occlusal screw access holes. Anterior guidance may be compromised when these screw access holes interfere with protrusive and lateral excursions¹.

Retention

The most important factor affecting implant prostheses longevity is security of retention. Several factors affect the retention of cement-retained restorations such as “taper of abutment, surface area and height, surface roughness, and type of cement”¹.

For screw-retained restorations, retention is achieved by fastening a screw and loss of retention is described as screw loosening. Factors that will affect the amount of retention include “insufficient clamping force, screw settling, biomechnical overload, off-axis centric forces (forces that are not directed along the long axis of the implant), implant components and prothesis misfit, differences in screw material and design, and finally hex height and implant diameter”¹.

Retrievability

Predictable retrievability can be achieved with screw-retained restorations without damaging the restoration—allowing for “prosthodontic components to be adjusted, screws to be refastened, and fractured components can be repaired with less time and at a lower cost than would be the case with cement-retained restorations”¹.

Clinical Prosthesis Fit

Substantial stress within the prosthesis, the implant, and surrounding bone may be created when there is not a precise fit between the crown and abutment in a screw-retained restoration. Some leading factors that affect the restoration fit depends on “accuracy preformed in the fabrication process such as impression technique, master cast accuracy, component tolerance, casting tolerance, and skill of the technician, while the type of retention does not play a role in transferring or compensating for inaccuracies of prosthesis fabrication”¹. However, screw-retained prostheses have been determined to produce tighter margins than cement-retained protheses.  

According to the review, many authors believe cement-retained prostheses are more likely to achieve a passive fit than a screw-retained one. But the review points out this increased passivity of cement-retained restorations “rests on the assumption that the cement could act as a shock absorber and reduce stress to bone and implant-abutment structure”¹. They also conclude cement-retained prostheses have the risk of bacteria colonization within the margins that may result in cement dissolution and gingival inflammation.

Effects on the Health of Peri-implant Tissue

Gingival inflammation was found to be an issue with cement-retained prosthesis because of the difficulty in removing the excess cement—especially when the prosthesis margin was greater than 3mm subgingivally. When excess cement is not removed completely, complications can arise such as peri-implant inflammation, soft tissue swelling, soreness, bleeding or exudation on probing, and resorption of peri-implant bone¹. According to Shadid and Sadaqa, these clinical situations can be solved by using either screw-retained restorations or custom abutments for cement restorations. They also found the gingival response to be better when using screw-retained crowns since no cement was used.

Provisionalization

When using provisional restorations, the review reports screw-retained provisional restorations are preferred over cement-retained restorations “because the screw can be used to seat the provisional restoration and to expand peri-implant mucosa”¹. Furthermore, they can be screwed into the master impression to send additional information to the technician about the contours¹. For cement-retained provisional restorations, the main disadvantage is the difficulty of removing excess cement and the risk of cement residues causing gingival inflammation.

Immediate Loading

Screw retention is the best choice for immediate loading because it eliminates the use of cement and the associated “difficulty in removing excess from the peri-implant area that may interfere with healing and implant integration”¹. Interestingly, it has been found the interface of machined implant components are superior to any cement margin that can be developed¹.

Porcelain Fracture

Porcelain fracture is most commonly seen in screw-retained restorations because the screw access hole disrupts the structural integrity of the porcelain.

Clinical Perfomance

Most of the studies reported that screw-retained restorations have more complications during follow-up periods, but the percentage of these complications was generally minimal and controllable¹.

Conclusions

The review concluded that certain situations may call for either screw retention or cement retention because there are certain advantages and disadvantages to both methods. Based on the review, they have demonstrated that “one type of restoration is more appropriate than the other in some clinical situations”¹.

Pros and Cons of IPS e.max® Lithium Disilicate Glass-Ceramics for Dental Restorations

For more than a decade, clinical trials have recorded high chipping rates in porcelain fused to zirconia (PFZ) dental restorations because of the relatively weak bond between the porcelain veneer and strong zirconia core. Porcelain fused to metal (PFM) dental restorations experience veneer chipping as well, however, clinical evidence has shown they perform better than PFZ restorations [1]. The major problem with PFM restorations is the metal substructure does not provide the most appealing esthetics. Therefore, researchers and clinicians developed monolithic all-ceramic dental restorations in an attempt to resolve these issues. One such monolithic all-ceramic dental restoration was developed by Ivoclar-Vivadent called IPS e.max^® lithium disilicate.

When considering U.S. dental patient’s high demand for esthetically driven restorations, a dental professional must make informed decisions about the quality, longevity and esthetics of a dental restoration in order to have a high acceptance rate among their patients. Thus, the dental practice will be more successful by means of new and retained patients. This article will briefly analyze the pros and cons of lithium disilicate glass-ceramics.

Microstructure of Lithium Disilicate (LS₂)

Dental ceramics can be classified by their microstructure (i.e., composition of glass-to-crystalline ratio) [2]. Lithium Disilicate (LS₂) has a glass-based system (mainly silica) with crystalline fillers, formed by the controlled crystallisation of the glass material [2]. The crystalline filler particles are added to increase the strength of the glass-ceramic; cracks caused by stress are “arrested by the lithium disilicate crystals, providing a substantial increase in the flexural strength” [2].

Pros

One pro to lithium Disilicate glass-ceramic restorations is an observed low chipping and fracture rate [1]. Lithium disilicate has an unusual microstructure that contributes to its relatively high flexural strength of 360-400MPa. The spread of cracks is deflected, branched and blunted by lithium disilicate needle-like crystal structure – providing a substantial increase in the flexural strength [2]. In a 2015 study, Valenti evaluated the clinical performance of 110 lithium disilicate crowns over a 9-year period and found 2 crowns had core fractures and 1 crown chipped. They found the “overall survival probability was 96.1% up to 9 years, with a failure rate of 1.8%” [3].

Six other clinical studies (Richter et al. 2009; Nathanson 2008; Reich et al. 2010; Fasbinder et al. 2010; Bind 2011; Sorensen et al. 2009b) showed 97.9% of 237 IPS e.max ^® lithium d­­isilicate (CAD crowns) restorations survived after a mean observation period of 4 years. The 2.1% failure rate included 0.4% irreparable chipping, 0.4% secondary caries and 1.3% fractures. Glass-ceramics exhibit lower strength relative to Porcelain fused to zirconia but higher chip fracture resistance. High chip fracture resistance is due to an elongated grain structure that inhibits crack propagation and contributes to its toughness, while it limits the strength by “promoting crack initiation within a relatively coarse microstructure” [1].

Another pro is lithium disilicate has superior esthetics compared to other ceramic materials. The monolithic structure and glass-ceramic system of lithium disilicate allows the material to take on translucent and light diffusing properties. Natural enamel has translucent qualities that transmits light rather than reflect or scatter it. The optical compatibility between the glassy matrix and the crystalline phase minimizes internal scattering of the light as it passes through the material—high translucency depends on the transmission of light through the core material [2]. Sravanthi et al. study argues that the “core translucency therefore becomes one of the primary factors in controlling aesthetics and is a critical consideration in selection of materials.” The study used a reflectance spectrophotometer (records the amount of light reflected) to compare the translucency of crowns fabricated with three different commercially available all-ceramic materials including alumina - CAD-CAM Procera, Lithium disilicate - Pressable IPS e.max Press, Zirconia - CAD-CAM Lava [4]. Out of all three ceramic materials, lithium disilicate was found to have the maximum translucency even when the coping was at a 0.8mm thickness.

Lastly, glass-ceramics can be “readily etched and silanized at the intaglio surfaces, with attendant superior bonding to a support substrate” [1]. In other words, lithium disilicate has the ability to be easily etched or milled out of a homogenous material by computer-aided-design/computer-aided-manufacturing (CAD/CAM) digital systems. This technology assures acute accuracy of the fabrication of the designed restoration. The silanization of the restoration’s surface helps increase the hydrophobicity of the glass-ceramic.  

Cons

Although lithium disilicate crown applications have a high survival and success rate, they may be “less suitable for applications where stress concentrations can be high, e.g. FDP [fixed dental prosthesis] connectors” [1]. The 360-400MPa flexural strength of lithium disilicate is relatively weak compared to the 1,000MPa flexural strength of zirconia-based restorations. For this reason, FDPs with frameworks made of glass-ceramics require “larger connector areas to meet load-bearing requirements relative to their stronger zirconia counterparts” [1]. Whereas, lithium disilicate single crowns are supported by underlying dentin that exhibits greater strength and stability then lithium disilicate multiple-unit restorations. However, a 10-year study evaluated the long-term outcome of three-unit FDPs made from monolithic lithium disilicate ceramic (IPS e.max Press, Ivoclar Vivadent) and found that the survival and success rates were similar to those of conventional metal-ceramic FDPs [7].

Next, one study analyzed the friction and wear behavior of human enamel that opposed lithium disilicate restorations and found evidence of abrasive wear behavior of the opposing enamel [5]. Lee et al. found the “enamel that opposed lithium disilicate glass ceramic exhibited cracks, plow furrows, and surface loss, which indicated abrasive wear as the prominent wear mechanism.” It’s worth noting that adequate surface finishing of dental ceramics influences wear on opposing enamel and requires competent skills of the dental laboratory to achieve an acceptable polished surface. A rough surface will abrade the opposing enamel of a restoration and “it is highly recommended that the surface is finished and polished appropriately” [6].  

To conclude, the flexural strength of previous glass-ceramic materials was relatively weak until the development of highly esthetic and strong lithium disilicate glass-ceramics. The highly specialized monolithic structure of IPS e.max ^® lithium d­­isilicate by Ivoclar Vivadent can achieve great structural integrity with superior translucent esthetics compared to other all-ceramic materials. For this reason, Lithium disilicate is a viable option for dental patients who are seeking longevity and beautiful esthetics for their dental restoration.

How Do Dental Implants Work?

Dental implants are considered to be the best long-term solution for missing teeth. Though dental bridges are a cheaper alternative, over time a dental implant is more cost-effective, as it can last decades. A patient can treat an implant as they would their real teeth, remembering that brushing and flossing is just as important! Dental implants look, feel and function like real teeth.

A dental implant, usually made of titanium, takes the place of a missing tooth’s original root, connecting to the bone. They help to maintain the jaw bone’s shape and density. It can take two to six months for the bone to fuse around the implant. Once healing is complete, an abutment is attached to it. This is the device that joins the implant to a crown, which replaces the actual missing tooth.

Crowns are custom-made at a dental laboratory, like Iverson, to match your existing teeth. The crown is cemented or screwed onto the abutment to permanently keep it in place. Once the dental implant procedure is complete, the crown should be indistinguishable from the rest of your teeth.

For fixed multiple tooth replacement, custom-made crowns or bridgework can be attached to the abutments to replace missing teeth without disturbing the healthy teeth next to them, and while stopping bone loss in the jaw and maintaining facial features.

If you are missing all of either your lower or upper teeth (or just all of your teeth), there’s also the option of getting a removable implant-supported tooth replacement. Two to six implants may be used to support a lower denture, depending on the design of the removable replacement. On the other hand, a minimum of four implants are required to support an upper denture. Removable dentures are usually used to replace extensive tooth, bone, and gum-tissue loss, providing support for the facial skeleton, lips, and cheeks. An advantage of a removable denture is making the cleaning of the dental implants significantly easier.

Over time, dental implants have become much more efficient and affordable. They’re very widely used, as roughly 70% of adults in America are missing at least one tooth. If you think you may be a good candidate for dental implants, speak to an experienced dentist to review your options. If you don’t have enough existing bone in your jaw or you’ve had radiation to your jaw, possibly for treating cancer or something similar, dental implants may not be the best option for you. Also, if you’re a smoker, your dentist will probably ask you to quit, as smoking can increase infection and rejection risks for dental implants.

With the advent of technological advances in dental materials and procedures, the dental industry is being transformed for major improvements. The reach of cutting-edge dental lab products that improve esthetics, strength and longevity is still limited to a few and is yet to reach a majority of dental patients. In fact, the dental industry is more than a decade behind in adopting and integrating new technologies on a widespread basis compared to other industries in biomedical engineering, medicine, electronics, automotive, aeronautics, and others. With the assured future of digital dentistry, dental practices are encouraged to become part of the early majority of those staying on the forefront of dental technology.

All-ceramic restorations or metal-free restorations, such as porcelain fused to zirconia and full contour zirconia, are gaining huge momentum in the dental industry. They are highly regarded as being more reliable, longer lasting and more esthetically driven than conventional prosthetics such as PFMs (Porcelain fused to metal). Concerning PFMs, the porcelain layers fused to the metal alloy has be known to break off after a period of time allowing for a shorter life span, costing more in the long run. Not only is the durability compromised from PFMs, the metal substructure makes it difficult to control the transparency and color matching of the restoration. All-ceramic restorations, like IPS e.max® Lithium Disilicate, find extreme strength in their monolithic structure and because of the ceramic substructure having a close match to natural teeth than dark metal, the prosthetic is able to achieve the best esthetic outcome.

IDL’s manager from the Ceramic department stated, “Iverson Dental Laboratories is pleased to offer all-ceramic restorations for a wide range of indications. Using high strength, all-ceramic materials for our dental products is quickly gaining popularity due to the translucent quality of the prosthetic that mimics the appearance of natural teeth. Having more control over the opacity of the coping and substructure of the prosthetic greatly improves esthetic results therefore patient satisfaction.”

His assistant added, “The translucency of IPS e.max® veneers mimics natural teeth so closely that even you will have a difficult time seeing the difference between the two. Patients may not know to request a translucent material, but they do recognize the improvement that it makes.”

Iverson Dental Labs Announces Advanced Dental Veneers for Superior Aesthetics

Iverson Dental Labs has announced they are able to fabricate the most modern dental veneers available on the market for unparalled esthetics and durability. Recent advancements in the dental field have expanded the types of veneers offered to dental patients. Many types now require no preparation to the natural tooth and color matching is more exact with lifelike qualities. With the translucency of recent veneer ceramics, visible tooth surfaces receive an optimized natural look. With the advancement in ceramic materials for dental restorations, such as Bruxzir® by Glidewell, dental labs are able to create extremely strong and lifelike prosthetics then ever created before. Iverson uses only the most advanced ceramic materials for veneer manufacturing, including IPS e.max® Lithium Disilicate, Full Contour Zirconia, Porcelain Fused to Zirconia and Hybrid Nano Ceramic. 

A major benefit to modern ceramic dental veneers is the procedure requires less removing and shaping of the healthy tooth structure compared to dental crowns and/or dental implants. This benefit helps improve the esthetics and durability of the restoration because the ceramic veneer is directly laid over the natural tooth, giving it a natural appearance with the benefit of the natural tooth substructure providing stability and strength. Previous dental veneers often required much preparation to the tooth and were not as consistent in color matching as they are in modern dentistry. Not only do modern dental veneers improve the translucent appearance of teeth but they also improve the strength and function of them by requiring a less invasive dental procedure, compared to dental crowns that require more removal of the tooth structure.

Shedding some light on how modern veneers has improved from past veneer materials, Iverson’s certified lab technician stated, “Color matching is easier than ever before. Modern dental veneers are very difficult to stain, making them ideal for a desirable bright smile. Some ceramic materials such as full contour Zirconia is virtually unbreakable and can even with stand any damage after a strike from a hammer. Our modern veneers provide a natural, beautiful smile that is durable and will last for years to come.”

Talking specifically about IPS e.max, the lab technician continued to elaborate, “e.max veneers provide superior aesthetics compared to previous veneer materials. Part of the beauty of e.max veneers is the translucency of the material. This gives a more natural appearance to the tooth. The thin layers are perfect for patients because little to no preparation is needed on the natural tooth. Many dentists consider products such as e.max veneers are more beneficial because they reduce the risk of root canal therapy.”

Dentists and their patients who seek highly esthetic and durable quality for their dental restorations are finding their expectations are exceeded by Iverson’s customized dental prosthetics. Iverson’s dental bridges, dental crowns, dental veneers and many other dental lab products are manufactured at a faster rate and find a reduction of material and labor costs by utilizing the latest in digital dentistry. CAD/CAM digital systems, such as Cerec Connect Lab, within the field of Digital dentistry are enhancing the esthetics, strength and production rate of dental products. Now with CAD/CAM digital systems, the dentist can send digital impressions of their patient’s teeth instantly to the dental laboratory to start production immediately. Then dental lab technicians virtually design the restorations according to treatment and next milled by CAD/CAM milling machines from ceramic materials for the most predictable results the dental laboratory has seen yet. With these new technological advances, the dental laboratory can increase their productivity with reliable and superior esthetic outcomes every time.
