Evaluation of secondary alveolar bone grafting outcomes performed after canine eruption in complete unilateral cleft lip and palate.

OBJECTIVES

Evaluate the results of secondary alveolar bone grafting (SABG) in patients with complete unilateral cleft lip and palate (UCLP), operated after permanent canine eruption (CE).

MATERIALS AND METHODS

Seventy-four periapical radiographs from patients with complete UCLP (mean age 14 years) submitted to SABG were retrospectively analyzed for the amount of bone in the cleft site through the Bergland and Chelsea scales.

RESULTS

Of the cases, 47.3 % was classified as Bergland type I and Chelsea type A, 35.2 % as type II/C, 6.7 % as type III/D, and 10.8 % as type IV/failure. When the canine was moved into the grafted area, the success rate (type I/A) was 56.8 %; for cases in which the space was maintained for an implant or prosthetic finishing, the index was 45.8 %; however, this difference was not statistically significant.

CONCLUSION

Even in advanced ages, after permanent canine eruption, SABG can be considered a highly successful procedure.

CLINICAL RELEVANCE

This research shows good results of secondary alveolar bone grafting performed in patients with unilateral complete cleft lip and palate, even when it was performed after eruption of the permanent canine in the cleft area.
