What this Trial Is About
Researchers are evaluating the clinical performance of a new dental implant design called the dual-cantilevered single implant bridge (T-Bridge). This design uses monolithic zirconia bonded to a titanium base abutment and aims to assess implant and prosthetic survival and success rates over 10 years. The study focuses on patients with dental implant failures needing fixed prostheses. Participants will receive one of two types of implant-supported dental prostheses: either the experimental dual-cantilevered single implant bridge supporting three units on one implant or a traditional 3-unit fixed dental prosthesis supported by two implants. The study is randomized and single-masked, comparing these two device-based treatments to evaluate their long-term outcomes. During the study, participants will be monitored for implant and prosthetic survival and success, as well as any complications over a 10-year period. The involvement includes clinical evaluations and follow-ups to track the performance and safety of these implant-supported prostheses. The total duration of outcome measurement spans a decade, ensuring thorough assessment of the treatments.
