About

The cleft patients received alveolar bone graft(ABG) for alveolar defect. Body mass index (BMI) was measured for each patients when receiving ABG. Bone mineral density was measured by Cone-Beam CT at two time-points: post-ABG six months, and post-ABG two years. The study was to analyze the correlation between BMI and post-operative bone mineral density.

Full description

Although childhood obesity is a growing issue, the association between BMI and the progressive bone mineral density (BMD) in grafted tissue after secondar alveolar grafting (ABG) remains little reviewed. This study compared the correlation between BMI and the progressive BMD after ABG procedure. Thirty-nine patients with unilateral or bilateral clefts were enrolled. ABG was performed at mixed-dentition age. Patient were classified into underweight, normal weight, and overweight or obese based on age- and sex-adjusted BMI. BMD was expressed in Hounsfield unit (HU) on cone-beam computed tomography (CBCT), which was obtained at 6 months (T1) and 2 years (T2) postoperatively. Calibrated BMD (HUgrafted tissue/HUpogonion¬, BMDc) was used for further analysis.

39 participants in 1 patient group

cleft patients received alveolar bone grafting

Description:

alveolar bone grafting was performed when the cleft patients were aged around 9 years old. CBCT was used to analyze the bone mineral density of grafted tissue.
