Evaluation of Multilayered PRF in Comparison With Connective Tissue Graft by Sohn Poncho's Technique on Peri-implant Mucosal Enhancement in the Esthetic Zone

12 de junio de 2026 actualizado por: Gulf Medical University

Evaluation of Multilayered PRF in Comparison With Connective Tissue Graft by Sohn Poncho's Technique on Peri-implant Mucosal Enhancement in the Esthetic Zone. A Randomized Clinical Trial

An effective biological seal is crucial for protecting and supporting dental implants, particularly in the anterior region for the desired esthetic outcome.PRF membrane and CTG has been utilized to improve peri-implant soft tissue thickness and increase the width of keratinized tissue around dental implants. The stability of the PRF membrane is maintained by securing it with the healing abutment of the implant. While a few longitudinal studies have assessed the benefits of using PRF membrane with Sohn's Poncho technique in the posterior region, its effectiveness in the anterior region of the mouth remains to be evaluated.

Descripción general del estudio

Descripción detallada

An effective biological seal is crucial for protecting and supporting dental implants, particularly in the anterior region for the desired esthetic outcome.13, 14 Recent studies have shown that the multilayering of the PRF membrane around implants have the same effect on peri-implant mucosal thickness in comparison to the gold standard which is the connective tissue graft without further patient morbidity 13, 14. PRF membrane and CTG has been utilized to improve peri-implant soft tissue thickness and increase the width of keratinized tissue around dental implants. The stability of the PRF membrane is maintained by securing it with the healing abutment of the implant. While a few longitudinal studies have assessed the benefits of using PRF membrane with Sohn's Poncho technique in the posterior region, its effectiveness in the anterior region of the mouth remains to be evaluated.7, 8 Additionally, the stabilized PRF membrane ensures prolonged exposure of the wound site to bioactive growth factors. Given these advantages, the potential benefits of using PRF membrane with dental implants in the anterior region need further exploration. Thus, this study focuses on comparing multilayering PRF membrane with the gold standard which is the CTG in healing period of 2nd stage implant surgery.

The test group will be treated with dental implant + multilayered PRF membrane. In brief, local anesthesia will be administered, and a crestal incision will be made to access the implant site. A full thickness mucoperiosteal flap will be reflected, exposing the underlying bone. The osteotomy will be performed following the implant manufacturer's guidelines, and a titanium implant will be placed at the planned position. For the purposes of standardization, implants will be placed at subcrestal level in both the groups. In the test group, at 4 months post-implant placement, a small incision will be made to place the healing abutment. Simple interrupted sutures will be used to approximate the tissues.
