【 摘 要 】

Aims: A retrospective observational cohort study to: 1. Determine the success of secondary alveolarbone grafting (SABG) definedby spontaneous canine eruption. 2. Investigate the influence of the following factors on canine eruption; Post-Operative Bone Fill Index; Age at SABG; Presence of lateral incisor; Horizontalposition and angulation of the canine; Expansion prior to SABG and Unilateral or bilateral cleft. Method: Records of 66 subjects amounting to 86 clefts were examined to determine the height of bone post-SABGusing the Post-Operative Bone Fill Index as well as the eruptive status of the canine.Study models, radiographs and clinical entries were used to determinethe presence and morphologyof the lateral incisor, position of the uneruptedcanine and presence of expansion. Results: 74.4% of 86 canines erupted spontaneously. Using the Post-OperativeBone Filllndex, 54.4% scored 1, 26.7% scored 2, 10.5% scored 3 and 8.1% scored 4. 52.3% of c lefts were associatedwith missing lateral incisors and 30.2% were expandedpre-SABG.There was no statistical significantcorrelation (P>0.05) between spontaneous eruptionand any of the variables. Conclusion: There was a good successrate of SABG, however, the height of bone post-SABG was not statistically con•elated with spontaneous canine eruption.
