Apically Positioned Flap vs Rolled Flap for Soft Tissue Management During Implant Second-Stage Surgery
Peri-Implant Soft Tissue Management During Second-Stage Surgery With Two Different Flap Techniques: A Randomized Controlled Study
Patients are being asked to consider joining a research study that looks at two different ways dentists uncover dental implants during a small gum surgery. To join this study, Patients must have two dental implants that are ready to be uncovered. Both uncovering methods used in this research are normal, safe procedures that dentists already use every day. The purpose of this study is to learn which method helps the gums heal better, stay thicker, and look more natural over time.
If patients decide to participate, the dentist will use one method on one implant and the other method on the second implant so we can compare how each implant heals. The study lasts about one year and includes the uncovering surgery plus scheduled follow-up visits. At these visits, the dentist will gently measure your gums, take pictures, take routine dental X-rays, and use a small camera scanner to check how the gum tissue changes. Patients will also be asked to rate any pain or swelling after surgery.
Patients may have soreness, swelling, or minor bleeding-these are the same risks patients would have during normal implant care. Patients may or may not personally benefit, but the extra monitoring may help us track the healing closely, and patients' participation can help dentists improve care for future patients.
Patients can receive regular implant treatment without joining the study. The goal of this summary is to help you think about the pros and cons and decide what feels right for patients.

|---|---|
|
Comparador Ativo: Apically Positioned Flap (APF)
During implant second-stage surgery, a crestal incision with vertical releases is used to elevate a flap that is repositioned apically and buccally to increase the width of keratinized tissue around the implant, followed by placement of a healing abutment and suturing.

A flap design used during implant second-stage surgery in which a crestal incision with vertical releases is performed, and the flap is repositioned apically and buccally to increase the width of keratinized tissue around the implant.
|
|
Experimental: Rolled Flap Technique (RFT)
During implant second-stage surgery, a full-thickness flap is elevated, and a pedicled connective tissue portion is de-epithelialized and rolled toward the buccal aspect to increase peri-implant soft tissue thickness, followed by placement of a healing abutment and suturing.

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Change in Keratinized Tissue Width
Prazo: Baseline (second-stage surgery) to 12 months after surgery
|
Keratinized tissue width will be measured clinically in millimeters at the mid-buccal aspect of the implant using a periodontal probe at prespecified follow-up visits.
|
Baseline (second-stage surgery) to 12 months after surgery
|
|
Change in Peri-Implant Mucosal Thickness
Prazo: Baseline (second-stage surgery) to 12 months after surgery
|
Peri-implant mucosal thickness will be assessed by superimposing serial intraoral scan data to quantify changes in buccal soft tissue thickness at implant sites over time.
|
Baseline (second-stage surgery) to 12 months after surgery
