Soft tissue behavior around dental implants placed in fresh extraction sockets and immediately restored in esthetic area: a preliminary short-term evaluation

AbstractObjective : To assess the behavior of the peri-implant soft margin after immediate implant placement with immediate function, by (1) direct clinical measurements of peri-implant soft margin height and thickness, (2) measurements of peri-implant soft margin height on photographs and (3) the perception of dental professionals regarding the results considering esthetic parameters. Material and method: The study included 8 patients with central or lateral incisors indicated to be extracted. Direct measurements of peri-implant soft margin height and thickness were done immediately before extraction (T0) and 1 (T1), 4 (T2), 8 (T3) and 12 (T4) months after the flapless insertion of the implant. Photographs were taken at the same time intervals. A questionnaire was filled in by implantology professionals regarding their visual perception of color and peri-implant soft margin architecture and harmony in the implant region using the photographs obtained at T4. Result : The clinical results showed significant changes to the height of the peri-implant soft margin, but the photographic results did not show significant changes for this measurement. The thickness of the attached gingiva was maintained during all the observation period. Of the professionals interviewed, 35.2% noticed an altered peri-implant soft margin color of the implant region, 39.8% noticed a change in the peri-implant soft margin architecture and 12.5% noticed a change in the peri-implant soft margin harmony.
