FACTORS PREDICTING THE SUCCESS OF SECONDARY ALVEOLAR BONE GRAFTING IN CLEFTS

Abstract

This study aims to evaluate the variables influencing the outcomes of secondary alveolar bone grafting in cleft patients. Materials and Methods: A retrospective review of 18 patients using medical records and conventional periapical radiographs. These variables include permanent canine eruption age, cleft type and width, flap technique, type of bone graft, the use of barrier membranes, autologous growth factor, and the timing of orthodontic tooth movement. The outcome variables were the cumulative scores of bone bridge and bone density. Statistical analyses were performed through univariate and multivariate logistic regression (P < 0.05). Results: Orthodontic tooth movement within three months after bone grafting demonstrated a fivefold higher success rate compared to movement after three months in both univariate and multiple regression analyses. Conclusion: The timing of orthodontic tooth movement emerged as a critical factor affecting the outcomes of secondary alveolar bone grafting in cleft patients.
