ABSTRACT
AIM:
To assess the 5-year effects of grafting connective tissue while undertaking single immediate implant placement and provisionalization at the mid-buccal mucosa level (MBML). Secondary outcomes were buccal bone wall thickness (BBT), marginal bone level (MBL) and patient satisfaction. MATERIALS ANDMETHODS:
Sixty patients with a single failing tooth in the maxillary anterior region were provided with an immediately placed and provisionalized implant. At implant placement, the patients randomly received either a connective tissue graft from the maxillary tuberosity (n = 30, test group) or no graft (n = 30, control group). The alveolar socket classification was mainly Type 2A. Data were collected before removing the failing tooth (T0 ), and at 1 (T1 ), 12 (T12 ) and 60 (T60 ) months after final crown placement. The primary outcome was the change in MBML compared with the pre-operative situation. Additionally, the change in BBT, MBL, aesthetics (using the Pink Aesthetic Score-White Aesthetic Score), soft-tissue peri-implant parameters and patient satisfaction were assessed.RESULTS:
At the 5-year follow-up, 27 patients could be analysed from each group. In each group, one implant was lost during the osseointegration period, within 3 months of placement, resulting in an implant survival rate of 96.7% in both groups. MBML change at T60 was -0.6 (-1.1 to -0.1) mm in the control group and 0.1 (-0.4 to 0.5) mm in the test group (p = .008). BBT and MBL, aesthetics, soft-tissue peri-implant parameters and patient satisfaction showed stable results and satisfied patients, without clinically relevant differences between the groups.CONCLUSIONS:
This 5-year follow-up study shows that grafting connective tissue when replacing a single failing tooth with immediately placed and provisionalized implant results in favourable peri-implant tissues and fewer MBML changes.Palavras-chave
