CHANGES IN ALVEOLAR BONE HEIGHT IN DISEASE
1. Reduced bone height
A. the height of the bone health and gingivitis. Health and gingivitis, crest of the alveolar bone is approximately 2 mm apical (see below) CEJs teeth (Fig. 3-9).
B. bone height in Periodontitis. In periodontal disease, the bone destruction can be serious (Fig. 3-10). And as the progression of periodontal disease (it does), tooth loss may occur due to the absence of the alveolar bone support (Fig. 3-11).
