How Periodontitis Repairs Alveolar Bone

Periodontitis is a chronic inflammatory disease of the periodontal supporting tissues, primarily caused by local factors. It most commonly occurs after age 35. If gingivitis remains untreated, the inflammation may spread from the gingiva deeper into the periodontal ligament, alveolar bone, and cementum, thereby progressing to periodontitis. Below, we address the question of how alveolar bone regeneration is achieved in periodontitis.

How Alveolar Bone Regeneration Is Achieved in Periodontitis

Alveolar bone regeneration in patients with periodontitis typically requires periodontal surgery. During the procedure, the gingiva is reflected to expose the underlying structures, allowing direct visualization and thorough removal of calculus and diseased granulation tissue from root surfaces or furcation areas. Subsequent steps may include contouring of the gingiva and alveolar bone, bone grafting, or resection of severely affected roots. Currently, guided tissue regeneration (GTR) procedures have yielded promising results in the treatment of periodontitis—particularly in promoting regeneration of cementum, periodontal ligament, and alveolar bone within the affected sites.

The clinical hallmarks of chronic periodontitis include gingival inflammation, formation of periodontal pockets, alveolar bone loss, and tooth mobility. Disease severity is assessed based on probing pocket depth, clinical attachment loss, and extent of alveolar bone resorption, and is generally categorized as mild, moderate, or severe.

The primary therapeutic goals for chronic periodontitis are complete elimination of local irritants—such as dental plaque and calculus—resolution of gingival inflammation, reduction of periodontal pocket depth, improvement of periodontal attachment levels, and long-term maintenance of these therapeutic outcomes.

Initial management involves basic non-surgical periodontal therapy, including scaling and root planing to effectively remove plaque and calculus, extraction of non-restorable teeth, occlusal adjustment, and adjunctive pharmacotherapy when indicated. One month after completing initial therapy, a follow-up evaluation is performed. If residual periodontal pockets ≥4 mm persist, if residual calculus remains inaccessible in certain areas, or if bleeding on probing persists, surgical intervention is warranted.

Regular monitoring and follow-up care are essential. Clinical assessments should include evaluation of plaque and calculus accumulation, gingival inflammation status, probing pocket depth, and the degree of alveolar bone loss and regeneration—and appropriate interventions should be implemented accordingly.

The above outlines how alveolar bone regeneration is approached in periodontitis. We hope this information is helpful to you.
