Implant-Supported Fixed Prosthetic Rehabilitation in Cases with Anterior Alveolar Bone Loss: A Report of Two Cases

INTRODUCTION: Anterior tooth loss, especially when

associated with alveolar bone resorption, presents considerable

challenges in both aesthetic and functional rehabilitation.

Implant placement in the anterior maxilla requires precise

treatment planning due to anatomical limitations and high

patient expectations. In cases with ridge defects, prosthetic

modifications such as restoring adjacent teeth may be

necessary to achieve optimal results.

CASE REPORTS: Case 1: A 48-year-old systemically healthy

male presented with aesthetic dissatisfaction concerning

implants placed in regions 11 and 21 after extractions five years

prior. Although peri-implant bone levels were stable, moderate

alveolar ridge resorption was evident. To enhance aesthetic

integration, full crowns were planned for adjacent teeth 12

and 22. Diagnostic impressions and mock-up evaluations were

performed, followed by tooth preparations and temporary

prothesis. Zirconia-based porcelain restorations were fabricated

after preparation and impression procedures.Final implant- and

tooth-supported prostheses were delivered after framework tryin. At the 6-month follow-up, no complications were reported.

Case 2: A 27-year-old healthy male, who had received implants in

regions 11 and 21 after trauma-related tooth loss, presented with

aesthetic concerns. Clinical evaluation revealed excessive gingival

display of teeth 12 and 22 and significant anterior ridge resorption.

Full crowns were planned for these teeth to optimize soft tissue

contours. Zirconia-based porcelain restorations were fabricated

after preparation and impression procedures. Definitive prostheses

were successfully placed following occlusal adjustments.

DISCUSSION: These cases highlight the importance of

comprehensive prosthetic planning in managing anterior

implant restorations, particularly when alveolar bone loss is

present. Restoration of adjacent teeth with full crowns allowed for improved pink-white aesthetic balance. Zirconia ceramics

offered favorable outcomes in terms of biocompatibility and

translucency. Both patients achieved satisfactory functional

and aesthetic results, maintained through routine follow-up.
