BACKGROUND: This study aims to evaluate soft and hard tissues response of a two-piece implant placed nonsubmerged in elderly patients' anterior maxilla. Marginal bone level and Pink Esthetic Score (PES) were evaluated up to 24 months. METHODS: Twelve healthy consecutive patients (mean age 65.8±5 years; 65.5 median) were included in the study. Implants were inserted with flapless technique after 3 months or immediately after extraction. The smooth machined neck of the implant was characterized by a hyperbolic neck which follows biologically oriented preparation technique (BOPT) principles. A customized abutment and a provisional resin crown was positioned with care to avoid excessive soft tissue compression after 3 months, according with BOPT technique. A definitive ceramic crown was positioned after approx. 4 months. RESULTS: After 24 months all implants were stable and osseointegrated. PES improved at 6 and 12 months recalls, remaining stable at 24 months, indicating a healthy soft and hard tissue response. No complications were observed. Impression procedures and provisional/definitive crown cementation resulted simple and free from complications. The hyperbolic profile allowed the preparation of prosthetic crown free from any gingival tissue pressure to create the ad¬ equate soft tissue contour. CONCLUSIONS: The use of hyperbolic profile implant associated with the transmucosal (not-submerged) technique is a safe procedure that allow the preservation of soft and hard tissue also in elderly patients.
