目的提出评价牙槽突裂植骨疗效的三维分级标准,完善Bergland评价系统.方法本研究选择于2014年1至4月在北京大学口腔医学院·口腔医院就诊的单侧完全性唇腭裂患者40例,均在二期牙槽突裂植骨术后3个月拍摄植骨区牙槽突局部锥形束CT片,提出牙槽突高度分级(H-Ⅰ～H-Ⅳ级)、厚度分级(T-Ⅰ ～T-Ⅳ级)、牙槽突综合分级(H+T)及临床成功标准(高度和厚度总分级均为Ⅰ或Ⅱ级时,属于临床成功型).结果 33侧植骨区牙槽突高度为临床成功型(18侧H-Ⅰ级和15侧H-Ⅱ级),牙槽突厚度属于临床成功型(总分级为T-Ⅰ级或T-Ⅱ级)共有25侧.结论牙槽突裂植骨疗效的三维评价方法能够更全面地评价牙槽突植骨的真实情况,尤其是牙槽突厚度.

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.
