Applications of a minimally invasive roll flap technique in peri-implant soft-tissue augmentation – A case series

Abstract

Deficiency of peri-implant tissue contours is commonly seen due to the process of alveolar ridge resorption after tooth loss. Minor deficiencies can be effectively managed by soft-tissue augmentation procedures to create a more biomimetic tissue contour. The minimally invasive roll technique is a modification of the palatal roll-flap technique and can be carried out at both stages of implant surgery. In this technique, the crestal keratinized tissue is marked and de-epithelialized using a circular partial-thickness incision. The crestal connective tissue is then reflected using a lingual full-thickness semi-circular incision, keeping the buccal attachment intact. This buccal attachment serves as the pedicle. The crestal connective tissue is then rolled into a pouch on the buccal aspect of the ridge to obtain soft-tissue augmentation. The present case study documents the clinical results of the minimally invasive roll flap technique (MIRT) in three clinical scenarios, namely single-stage implant surgery, second-stage implant surgery, and anterior esthetic soft-tissue contouring. In all the cases, excellent soft-tissue contour and thickness has been obtained around dental implants. The MIRT is a simple and efficient technique for areas that require minor soft-tissue augmentation. The technique can be used both in the maxilla and the mandible and facilitates a suture-free surgery.
