Comparing two methods for fixing dentures in edentulous jaws

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the marginal bone changes in edentulous patients receiving fixed mandibular prostheses using two different attachment systems: conventional screw retained multiunit abutments and the OT bridge attachment system. Patients will be divided into two groups, with both undergoing implant placement guided by a surgical template. The study aims to assess the effectiveness of the OT bridge attachment system compared to traditional methods in maintaining bone integrity around the implants. Participants will be monitored over a healing period of eight to twelve weeks post-implant placement.
