ABSTRACT
OBJECTIVES:
To evaluate the volumetric changes and peri-implant health at implant sites with and without previous soft tissue grafting over a 12-year observation period. MATERIALS ANDMETHODS:
Eighteen patients received dental implants and simultaneously guided bone regeneration in the esthetic zone (15-25) for dental rehabilitation. Three months following implant placement, 8 patients (test) received an additional subepithelial connective tissue graft, whereas 10 patients (control) did not receive any additional treatment. One week after prothesis delivery and at the 5 and 12 years follow-up examination, impressions were taken. Obtained casts were processed for profilometric and linear analyses. The mean distance (MD) in the mid-buccal area between the two surfaces was considered the primary outcome. Peri-implant health was assessed based on clinical and radiographic data.RESULTS:
Nine female and 7 male patients were re-assessed after a median follow-up time of 144.5 months (Min 114.8; Max 213.0). The median reduction of MD amounted to -0.81 mm (Min -1.39; Max 0.52) in the test group and -0.56 mm (Min -0.93; Max 0.11) in the control group, (intergroup comparison p = .607, CI 95% -0.760/0.530). None of the implants was diagnosed with peri-implantitis. Six tests and two control implants were diagnosed with peri-implant mucositis (p = .103).CONCLUSIONS:
Despite the limited number of included patients, similar results in terms of volumetric, linear changes, and peri-implant conditions could be detected at implant sites with or without soft tissue grafting over a period of 12 years.Palavras-chave
