Description
Alveolar ridge augmentation rebuilds jawbone volume for dental implants after bone loss, with costs ranging ¥3,000–¥8,000 in China; ChinaMedicalHub assists with hospital coordination and interpreter support.
Main Uses
Primary purpose is to restore deficient alveolar ridge dimensions (height/width) to enable successful dental implant placement. Key indications include: severe alveolar ridge atrophy following tooth extraction or long-term edentulism, failed previous implant attempts due to insufficient bone, congenital defects (e.g., cleft-related alveolar deficiency), traumatic bone loss, and periodontal disease–induced vertical/horizontal bone loss requiring implant-supported rehabilitation.
Normal Range
Alveolar bone augmentation is a surgical procedure, not a laboratory test with numerical values; therefore, there is no 'normal range' of quantitative measurements. Clinical success is assessed qualitatively and semi-quantitatively via radiographic imaging (e.g., CBCT) and clinical evaluation: adequate bone height (>8–10 mm), width (>5–6 mm), density (Hounsfield units ≥350–700 HU on CBCT, depending on site), and stable integration of grafted material without resorption or infection.
Low Values - Possible Causes
Inadequate bone volume post-augmentation due to: 1) Early graft failure or resorption, 2) Infection (e.g., osteomyelitis or peri-implantitis), 3) Poor vascularization or compromised blood supply (e.g., in smokers or diabetic patients), 4) Excessive mechanical loading or premature functional loading, 5) Use of suboptimal graft material or technique (e.g., insufficient primary stability, lack of barrier membrane).
High Values - Possible Causes
Apparent 'high' bone volume is not clinically pathological but may reflect: 1) Overcorrection during surgery (excessive grafting), 2) Reactive bone formation or heterotopic ossification (rare), 3) Chronic low-grade inflammation leading to sclerotic bone changes, 4) Pre-existing bony exostosis or torus adjacent to the augmented site, 5) Artifact or measurement error on imaging (e.g., beam hardening on CT).
