Crown Materials Used to Best Replicate Natural Teeth
The latest technology in dental restoration includes the custom-made construction of implant crowns using porcelain material fused to metal, and porcelain fused to zirconia. Considering their realistic appearance and feel, they’re a popular choice among patients and are highly recommended as a replacement for damaged or missing teeth.
What Types of Implant Crown Retention are Most Suitable for London Patients?
How an implant crown is secured to the implant itself is a vital step in the overall process. There are two main retention methods usually available to patients, being screw-retained and cemented crowns.
While having their pros and cons, both can provide patients with excellent results. Read on for information on how they differentiate:
Screw-retained Crowns vs Cemented Crowns
Both these systems have their advantages and disadvantages. Screw-retained implant crowns, while preferred for their ease of removal and their lack of need for cement securement, may not always be possible. Reason being, this system depends on the positon of the bone. In cases where screw access is visible, a screw-retained crown system may not be aesthetically acceptable.
The good news for patients is, there is always an adequate solution to each case. The costs are the same, with both options providing excellent results if used correctly.
Cemented crowns require a two-piece assembly, in which an abutment is attached to the implant with a screw. Following this, the implant crown is cemented onto the abutment.
This option is natural in appearance, has no screw access hole, and offers superior cosmetic flexibility to screw-retained crowns. In rare instances, inflammation of surrounding soft tissue can occur as a reaction to the cement. Additionally, there are limited removal options available.
Cemented crowns aren’t dependent on the implant’s angulations, and are natural in appearance. Also, they can be used universally in all cases.
Screw-retained crowns are attached directly to the implant with a screw. These crowns have the abutment and the crown itself fused in one single component, therefore not requiring an abutment, nor cement.
Post-procedure, they allow ease-of-access to the screw which allows for more efficient repair should issues arise. The implant access hole, while enabling quick fixes to minor issues such as loosening of the crown, can pose a risk of chipping to the porcelain crown. It’s also worth considering the inferior cosmetic appearance of screw-retained crowns.
Screw-retained crowns are easily removed if the need were to arise. For instance, the implant crown may require retightening should it become loose.
Depending on the case at hand, the access of the screw can compromise the aesthetic effect of the implant crown.
As to which retention method is most suitable, it differs per each patient’s individual requirements as determined by the implantologist.
3Shape TRIOS Scanner: Simplifying the Dental Implant Process
This cutting-edge technology will be used by our clinicians to scan teeth and implants, effectively replacing the traditional process of putty impressions. As a result, the procedural planning stage is far more efficient, ensuring highly accurate & detailed implant treatments.
In both screw-retained and cemented implant crowns, it’s recommended the patient has regular yearly checkups with their dentist. In addition to this, MIC advise on biannual visits to a hygienist to ensure the best ongoing oral health of the patient.
