Research Progress on Bone Defect of Adjacent Teeth after Mandibular Wisdom Tooth Extraction

doi:10.13701/j.cnki.kqyxyj.2025.08.002

Abstract

Abstract: The third molar in the lower jaw is the most frequently impacted tooth, with an incidence reaching up to 64.5%. The lower third molar typically causes damage to the periodontal tissue of adjacent teeth. In recent years, research on the dental alveolar bone defects in adjacent teeth following the extraction of impacted lower third molars has gradually drawn attention. Studies have revealed that the alveolar bone defects in adjacent teeth after the extraction of impacted lower third molars are influenced by various factors, such as the patient's age, the periodontal health status before the operation, the type of impacted lower third molar, and the extraction method. There are numerous forms of assessment and postoperative intervention for the alveolar bone defects in adjacent teeth after the extraction of impacted lower third molars. However, the existing methods and measures still have deficiencies, and more research is required to obtain more accurate assessment methods for bone defects and clear restoration standards. This article aims to summarize the research progress regarding the influencing factors, assessment methods, and postoperative treatment plans for the alveolar bone defects in adjacent teeth after the extraction of impacted lower third molars.

Key words: bone defect, impacted third molar in the lower jaw, second molar in the lower jaw, cone beam CT, bone graft, guided bone regeneration
