Randomized Study Comparing Tissue-level and Bone-level Two-piece Zirconia Implants for Single Missing Upper Premolars

What this Trial Is About

Researchers are evaluating two types of two-piece zirconia dental implants in adults with missing premolar teeth in the upper jaw. The study focuses on comparing implants with tissue-level platforms versus bone-level platforms. The goal is to assess implant stability, survival rates, and their effects on surrounding bone and soft tissue health over several years. The trial is randomized and triple-blinded to ensure reliable results. Participants will be randomly assigned to receive either a 10-mm long, 4-mm wide zirconia implant with a tissue-level platform or a similar implant with a bone-level platform. After implant placement, stability will be measured using the International Stability Quotient device. Three months after the implant, ceramic crowns will be placed. The study will continue to monitor the implants and surrounding tissues at 1, 3, and 5 years after placement. During the study, participants will undergo evaluations including measurements of crestal bone loss, probing depth, bleeding on probing, and volumetric tissue changes at baseline and during follow-ups at 1, 3, and 5 years. The researchers will track implant survival and health of the peri-implant tissues over time. Participants will be followed for a total of 5 years to provide long-term data on implant performance and tissue response.
