What this Trial Is About
Researchers are studying the temporary changes in gum volume that occur after an implant crown is removed in the esthetic zone, particularly in patients who had a maxillary anterior immediate implant and provisionalization. The main goal is to find out how long it takes to see a significant change in the gum shape, which is important when making a mold or copy of the gum for a new crown. This observational study focuses on these changes over a short period of time after crown removal. The study involves scanning the area around the implant crown using an intra-oral scanner immediately after the crown is removed and at multiple time points up to 15 minutes later. A tag will be placed on the implant to help record its exact location, and the patient's crown will also be scanned so all data can be combined to measure changes accurately. After scanning, the crown will be put back in place to allow the gum to return to its original shape. If the patient returns for a new crown, a final scan will compare gum shape changes between the old and new crowns. Participants will have their gums scanned right after crown removal and at 1, 2, 3, 5, 7, 10, and 15 minutes afterward. The study measures the volumetric change of the gum tissue and vertical gum margin differences. The scans and data help researchers assess how much and how quickly the gum changes. This study is sponsored by Loma Linda University and does not involve any treatments beyond the scanning and crown removal/reinsertion process.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Approximately 15 minutes
Participants undergo scans of the implant crown area immediately after crown removal and at multiple time points within 15 minutes to assess mucosal changes.
1 visit with multiple scans over 15 minutes (in-person)
Duration - Variable depending on new crown placement
Participants may return in the future for a final scan to compare changes in the gums between the old and new crown.
1 follow-up visit (in-person) if returning for new crown
