Abstract

Background: Clinical studies of single-tooth replacement in compromised bone using bone level tapered implants in the aesthetic zone are scarce.

Aim: To assess clinically, radiographically and aesthetically over 1 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) with a failing tooth and large bone defect after removal received alveolar ridge preservation. After 3 months, implants were placed with immediate provisionalization. Definitive restorations were placed after 3 months. The treatment was evaluated 1 year following the definitive restoration.

Results: All the patients attended the 1-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 1 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.
