Description
Guided Bone Regeneration restores jawbone volume for dental implants or trauma recovery, with costs in China ranging ¥5,000–¥15,000; ChinaMedicalHub helps coordinate hospital appointments and interpreter support.
Main Uses
Primary purpose is to regenerate deficient alveolar bone for dental implant placement; used in ridge augmentation (horizontal/vertical), sinus floor elevation, peri-implant defect repair, and treatment of periodontal osseous defects. Applicable scenarios include post-extraction socket preservation, congenital or traumatic bone loss, failed previous implant sites, and compromised ridges due to long-term edentulism.
Normal Range
Guided Bone Regeneration (GBR) is not a laboratory test with numerical values or a 'normal range'; it is a surgical procedure. Therefore, no quantitative reference intervals (e.g., mg/dL, mmol/L) apply. Success is assessed qualitatively and quantitatively via clinical evaluation and imaging: bone fill ≥70–90% of defect volume, radiographic density comparable to adjacent native bone, absence of infection or membrane exposure, and stable osseointegration of dental implants (if placed). Healing time typically ranges from 4–6 months.
Low Values - Possible Causes
Inadequate primary stability of barrier membrane, premature membrane exposure/infection, insufficient blood supply to the graft site, systemic factors (e.g., uncontrolled diabetes, smoking, osteoporosis), poor patient compliance (e.g., non-adherence to postoperative care or antibiotics), and use of non-resorbable membranes without proper tension control leading to collapse.
High Values - Possible Causes
Excessive bone graft volume causing soft tissue dehiscence or contour deformity, over-engineered barrier membranes inducing chronic inflammation or foreign body reaction, unintended ankylosis or heterotopic ossification (rare), excessive mechanical loading during healing, and concurrent use of high-dose bone morphogenetic proteins (e.g., rhBMP-2) leading to uncontrolled osteogenesis or swelling.
