  • Factors influencing alveolar bone remodeling after tooth extraction: a scoping review
    Publication . Aulagner, Pauline Alice Sylvine; Lopes, Otília; Nóbrega, Ana Rita
    Background: Following tooth extraction, the alveolar bone remodels through resorption and new bone formation. Early dimensional changes may compromise future prosthetic or implant rehabilitation. Identifying influencing factors is crucial for optimal outcomes. Objective: This scoping review mapped biological, environmental, and mechanical factors affecting alveolar bone remodeling in adults. Methods: Conducted according to PRISMA-ScR and PICo, searches were performed in PubMed, Scopus, Cochrane, Web of Science and Google Scholar (2005–2025). Eligible studies were systematic or narrative reviews, observational studies, and clinical trials in English or Portuguese. Exclusions included implant-only studies, rare systemic disorders, or highly specific surgical techniques. Of 788 records, 168 duplicates were removed, 620 screened, 72 assessed in full, and eight included. Results: Dimensional changes were most pronounced in the first 3–6 months, with horizontal loss up to 63% and vertical up to 22%, mainly at the vestibular wall. Biological factors included age, systemic conditions, and medications. Environmental influences such as smoking, oral hygiene, and nutrition also contributed. Mechanical factors—vestibular wall thickness, socket morphology, tooth type, and surgical technique—significantly affected ridge stability. Ridge preservation reduced bone loss by ~2 mm compared with extraction alone, though resorption remained unavoidable. Conclusion: Alveolar bone remodeling after extraction results from a complex interplay of biological, environmental, and mechanical factors. Preservation techniques mitigate but cannot prevent resorption. Standardized methods and further studies are needed. Patient-specific assessment remains essential for optimal planning.
