RESUMO
OBJECTIVE: To investigate the clinical results of use of healing abutment for sealing socket and preserving the gingival natural profile in single-tooth immediate implantation. METHODS: The osteotomy site was prepared with pilot drill directed by the periodontal probe on palatal wall of the socket,and 31 single-implant were placed into fresh sockets with flapless surgery and filled with Bio-oss. Healing abutments were simultaneously fitted on implants and ceramic crowns fabricated three months post-operation. Scientific assessment of soft tissue contour was carried out by interdental papillae index immediately after restorations. RESULTS: One implant was lost at second week after operation. The remaining 30 implants gained perfect osseointegration and the gingival natural profile was preserved completely. CONCLUSIONS: Sealing socket and preserving the gingival natural profile by healing abutment is a predictable, safe and practical method with good aesthetic results in single-tooth immediate implantation.
