Outcome after secondary alveolar bone grafting among patients with cleft lip and palate at 16 years of age: a retrospective study

ObjectiveTo evaluate the outcome of secondary alveolar bone grafting (SABG) in patients with cleft lip and palate at 16 years age to identify predictors associated surgical failure.Study DesignThis retrospective follow-up included 91 100 palates treated SABG a mean 9.2 years. The possible for failure analyzed were sex, dental development stadium, type cleft, side, tooth erupting into graft, cortical boundary, presence lateral incisor, extraction, preoperative expansion, oral hygiene, retention device, age. variable success was Bergland score I II. Surgical based on intraoral radiographs, according index. Statistical analyses estimation odds ratios predictor variables.ResultsThe post-SABG rate 91% (Bergland II) 7.2 significantly poor hygiene.ConclusionsThis study revealed high (91%) post-SABG. Poor hygiene increased risk failure. This suggests that perioperative measures maintain good health could reduce To variables. hygiene.
