Abstract:
Objective To propose a new three-dimensional method or grading scale in the evaluation of the secondary alveolar bone grafting,thus modifying the Bergland grading scale.Methods A total of 40 patients (26 male,14 female) with unilateral cleft lip and palate (UCLP),who underwent secondary alveolar bone grafting at least 3 months ago,were enrolled.Regional cone-beam CT(CBCT) scans were taken to evaluate the height and thickness of the postoperative bone bridges.A new three-dimensional grafting scale was established,including four grades respectively in alveolar height and thickness.Results According to the new three-dimensional scale in this study,15 grafted sites were rated grade T-Ⅰ or T-Ⅱ in the alveolar thickness among 18 sites of grade H-Ⅰ in height,and 10 among 15 of grade H-Ⅱ in height.Therefore,25 grafted sites were considered as clinical success in the alveolar thickness (grade T-Ⅰ or T-Ⅱ) among 33 sites with clinical success in alveolar height (grade H-Ⅰ and H-Ⅱ).There were 24％ of 33 sites with clinical success in height,which were considered as clinical failure in the alveolar thickness.Conclusions It is necessary to establish a new three-dimensional method or grading scale for evaluating the secondary alveolar bone grafting.The three-dimensional scale can take comprehensive view of the bone-grafted alveolar clefts and thus modify the Bergland grading scale.
