ClinConnect Summary

This clinical trial is studying the best timing for soft tissue grafting after placing an immediate dental implant in the front part of the mouth (the premaxilla). The goal is to understand whether performing the graft right after the implant surgery (called Immediate Soft Tissue Grafting) or waiting three months (called Delayed Soft Tissue Grafting) leads to better outcomes for preventing bone loss around the implant. Participants will have a small scan done before surgery to ensure they have enough healthy bone to support the implant and will then be randomly assigned to one of the two timing groups for the grafting procedure.

To qualify for this trial, you must be at least 20 years old, have good oral hygiene, and need to have a tooth removed in the front of your mouth, with a nearby healthy tooth still present. Other requirements include having enough bone for the implant and intact bone walls. If you join the study, you'll undergo the implant procedure, and depending on your assigned group, you'll receive the graft either immediately or three months later. Throughout the study, your progress will be monitored with follow-up scans one and five years after the procedure to check on bone health.
