Retro molar papilla pedunculated flap: A retrospective case series.

Abstract

Background: The primary purpose of this paper is to introduce a new flap design to improve keratinized tissue (KT) around implants in the posterior mandible, avoiding the need for harvesting tissue from the palate, which is associated with significant discomfort for patients.

Methods: Eleven patients requiring implants in the molar regions with a KT width (KTW) < 2 mm at the buccal aspect were treated using this surgical technique. Outcomes, including the increase in KT width and postoperative discomfort, were measured at intervals of 1, 4, and 10 months.

Results: An average increase of 4.2 mm in KT width was achieved. Postoperative pain was minimal, with most patients reporting low scores on the Visual Numerical Scale. No significant reduction in KT width was observed during follow-up.

Conclusion: Within the limitations of the present case series, the data suggest that this flap is a promising and less invasive technique for treating KT deficiency around implants, eliminating the need for palate harvesting. Further long-term studies are needed to confirm the stability of the results.

Plain language summary: This case series presents a new surgical method designed to improve the protective gum tissue (called keratinized gingiva) around dental implants in the back part of the lower jaw. This type of gum tissue is important because it helps keep implants stable and healthy over time. Traditionally, the best way to add this tissue is by taking a piece from the roof of the mouth, but that can be painful and lead to complications. In recent years, researchers have explored less invasive options, but most haven't matched the effectiveness of using the patient's own tissue. In this study, the new approach allowed the treatment of 11 patients who had too little gum tissue around their implants. The technique used the patient's own gum tissue but avoided taking it from the palate, making the procedure more comfortable. The results showed that this method was effective in increasing the amount of healthy gum tissue, offering a promising alternative that prioritizes both results and patient comfort.

Key points: Effective strategies for increasing keratinized tissue in Mandibular posterior areas. Minimal postoperative discomfort; minimally invasive surgery Stability of peri-implant tissues.
