Abstract

Introduction
Post-extraction bone resorption is a predictable physiological process, particularly affecting the alveolar ridge and posing a clinical challenge, especially in the esthetic zone. These dimensional changes may compromise implant placement and prosthetic outcomes. Alveolar ridge preservation has been proposed as a preventive approach to limit post-extraction atrophy and optimize pre-implant anatomical conditions.

Observation
Two clinical cases of alveolar ridge preservation following tooth extraction are presented. Atraumatic extraction techniques were performed to preserve hard and soft tissues. Socket management focused on blood clot stabilization and the use of biomaterials. Clinical and radiographic follow-up showed favorable healing and satisfactory preservation of ridge volume, enabling subsequent implant planning.

Discussion
Physiological remodeling after extraction leads to significant horizontal and vertical bone loss, particularly of the buccal plate. Alveolar ridge preservation has been shown to reduce these dimensional changes. The presented cases highlight the importance of atraumatic extraction, appropriate biomaterial selection, and careful surgical technique in achieving predictable outcomes. Although resorption cannot be completely prevented, its extent can be significantly minimized.

Conclusion
Alveolar ridge preservation is an effective method for reducing post-extraction bone loss and maintaining favorable conditions for implant placement. The reported cases support its role as a valuable component of implant-oriented treatment planning.
