Abstract

Aims: A retrospective observational cohort study to: 1. Determine the success of secondary alveolar bone grafting (SABG) defined by 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; Horizontal position 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-SABG using the Post-Operative Bone Fill Index as well as the eruptive status of the canine. Study models, radiographs and clinical entries were used to determine the presence and morphology of the lateral incisor, position of the unerupted canine and presence of expansion. Results: 74.4% of 86 canines erupted spontaneously. Using the Post-Operative Bone Filllndex, 54.4% scored 1, 26.7% scored 2, 10.5% scored 3 and 8.1% scored 4. 52.3% of c lefts were associated with missing lateral incisors and 30.2% were expanded pre-SABG. There was no statistical significant correlation (P>0.05) between spontaneous eruption and any of the variables. Conclusion: There was a good success rate of SABG, however, the height of bone post-SABG was not statistically con•elated with spontaneous canine eruption.
