INTRODUCTION: In single-tooth replacement in the aesthetic zone, extensive bone defects require alveolar ridge reconstruction. A digital workflow involving CBCT and intraoral optical scanning enables a three-dimensional assessment, prosthetically driven implant positioning, computer-assisted implant surgery, and prefabrication of a temporary restoration for immediate provisionalization. The aim of this study was to assess the clinical, aesthetic, radiographic, and patient-reported outcomes of delayed implant placement and immediate provisionalization in reconstructed alveolar ridges using a digital workflow.
MATERIALS AND METHODS: In a prospective case series, 30 patients with a > 5 mm buccal bone defect underwent alveolar ridge reconstruction. After 4 months, implant placement was performed using a digital workflow, followed by immediate provisionalization with a prefabricated temporary restoration, and definitive restoration 3 months later. The clinical, aesthetic, radiographic, and patient-reported outcomes were assessed pre-treatment, 6 weeks after provisionalization, and 1 month and 1 year following definitive restoration.
RESULTS: Wound healing was uneventful in 90% of cases (10% showed mild oedema). One early implant failure occurred (implant survival rate 97%). After 1 year, restoration survival and success rates were 100% and 97%. Peri-implant tissues were mainly healthy. The mean (SD) Pink and White Esthetic Score (scale 0-20) was 14.0 (2.9). The mean (SD) marginal bone level change was -0.25 mm (0.38) mesially and -0.21 mm (0.45) distally. The median buccal bone thickness was > 1.5 mm. Patient satisfaction (scale 0-10) was 9.3 (0.9).
CONCLUSION: A digital workflow offers favorable short-term clinical, aesthetic, radiographic, and patient-reported outcomes for single-tooth implants after alveolar ridge reconstruction.
TRIAL REGISTRATION: Registered in the National Trial Register: NL8264.
