Soft tissue remodeling technique as a non-invasive alternative to second implant surgery

It is currently accepted that success in implant-supported restorations is based not only on osseointegration, but also on achieving the esthetic outcome of natural teeth and healthy soft tissues. The socalled "pink esthetic" has become the main challenge with implant-supported rehabilitations in the anterior area. This is especially difficult in the cases with two adjacent implants. Two components affect the final periimplant gingiva: a correct bone support, and a sufficient quantity and quality of soft tissues. Several papers have emphasized the need to regenerate and preserve the bone after extractions, or after the exposure of the implants to the oral environment. The classical implantation protocol entails entering the working area several times and always involves the surgical manipulation of peri-implant tissues. Careful surgical handling of the soft tissues when exposing the implants and placing the healing abutments (second surgery) helps the clinician to obtain the best possible results, but even so there is a loss of volume of the tissues as they become weaker and more rigid after each procedure. The present study proposes a new protocol that includes the connective tissue graft placement and the soft tissues remodeling technique, which is based on the use of the ovoid pontics. This technique may help to minimize the logical scar reaction after the second surgery and to improve the final emergence profile.
