ClinConnect Summary

This clinical trial is designed to study different techniques for placing dental implants right after a tooth is removed, particularly in the front part of the mouth. The goal is to find out which method best helps maintain the bone and soft tissue around the implant, preventing loss as the area heals. To do this, 54 participants will be randomly divided into three groups, each receiving a different treatment approach. Before the surgery, participants will undergo a special type of imaging to ensure they have enough bone for the implant.

To participate in this trial, you should be at least 20 years old, maintain good oral hygiene, and have a tooth that needs to be extracted along with enough bone support for the implant. If you are pregnant, smoke, or have certain health conditions, you may not be eligible. Participants will have their progress monitored over the course of a year, with follow-up scans to assess how well the treatment worked. This study aims to improve dental implant procedures, making them more effective and beneficial for patients needing tooth replacements.
