NCT06056388

Brief Summary

The goal of this clinical trial is to compare the placement accuracy in immediately placed implants using dynamic navigation between deep-threaded and regular-threaded implants in partially edentulous patients. The main question it aims to answer is: is there a difference in implant placement accuracy between deep-threaded and regular-threaded implants using dynamic navigation? Participants will receive implants placed immediately under dynamic guidance. Researchers will compare type of implant thread (Straumann BLT versus Straumann BLX) to see if there are significant differences in placement accuracy.
