Condition: Dental Prosthesis Failure · Sponsor: Branemarkkliniken
In recent years, zirconia-based implant-supported bridge designs have begun to be used more and more as an alternative to metal ceramic bridges. Another new material that has been introduced in the clinic is the high translucent monolithic zirconia, which has only been investigated a few follow-up studies with short follow up duration. The aim being to evaluate the clinical outcome of implant-anchored posterior bridges, made from 1. high-translucent monolithic zirconia, 2. zirconia ceramic with porcelain and 3. metal ceramics. The hypothesis is that high-translucent monolithic zirconia has lower rate of complications since surface porcelain veneering is not required. A total of 60 research subjects will be included in the study. Patients in need of a permanent implant-supported bridge, located posterior of the canine in the upper or lower jaw will be asked for participation. Each subject will be treated according to standard treatment protocols with implants from Nobel Biocare, the Branemark implant system and then be randomly assigned to obtain one of the following three type of bridges. 20 research subjects will be included in each of the three study arms. The prosthetic treatment will be carried out according to standard clinic protocol. All research subjects will be evaluated after 1, 3, 5 years. X-rays and photos will be taken at the installation of the bridges and after 1 and 5 years of follow-up or more frequent, depending on individual indication of the patient a…
