80 Chapter 5 Abstract Aim : To assess clinically, radiographically and aesthetically over one year the performance of a bone level tapered implant in the maxillary aesthetic zone in sites after alveolar ridge preservation. Material and methods : Thirty patients (16 male, 14 female, mean age 43 years) with a failing tooth and large bone defect after removal, received alveolar ridge preservation. After three months, implants were placed with immediate provisionalization. Definitive restorations were placed after 3 months. The treatment was evaluated one year following the definitive restoration. Results : All the patients attended the one-year follow-up. One implant was lost (96.7% implant survival rate). The mean Implant Stability Quotient value was 68.9±8.74 at implant placement. The mean marginal bone level change was minor (-0.07±0.12 mm). The mean mid-buccal mucosa changed with +0.01±0.45 mm. The median Pink Esthetic Score and White Esthetic Score after one year were 6 [4;7] and 8 [7;9], respectively. The patients’ mean overall satisfaction (0-100 VAS scale) was 86.6±10.3. Conclusion : Bone level tapered implants with immediate provisionalization perform well after alveolar ridge preservation in the maxillary aesthetic zone, according to implant stability, clinical, radiographic, aesthetic and patient- centred outcomes.
