Abstract: Alveolar ridge preservation after tooth extraction can reduce or even prevent alveolar bone resorption and soft tissue collapse during the healing process. This helps avoid complex soft and hard tissue augmentation procedures and provides good soft and hard tissue conditions for implant surgery. While conventional alveolar ridge preservation techniques have been widely applied and have shown predictable outcomes, there is still no standardized protocol for alveolar ridge preservation in cases where teeth are extracted due to periodontitis or periapical inflammation. To improve the success rate of alveolar ridge preservation in these inflammatory extraction sites, it is necessary to understand the various influencing factors of alveolar ridge preservation. This review discusses the indications for alveolar ridge preservation in inflammatory extraction sites, the impact of inflammation on alveolar ridge preservation, the key steps of this technique, and the timing of implant placement. It also shares experiences and techniques to optimize treatment outcomes.

Key words: Alveolar ridge preservation in inflammatory extraction sites, Periodontitis, Periapical diseases, Bone regeneration
