URIBE FENNER, Francisca; CASTELLON ZIRPEL, Loreto y LAISSLE C, Germán. Permanent canine eruption through secondary bone grafts in patients with cleft lip and palate. Rev. Odont. Mex [online]. 2007, vol.11, n.4, pp.207-214. ISSN 1870-199X. https://doi.org/10.22201/fo.1870199xp.2007.11.4.15802.
This is a retrospective study which main purpose was to evaluate the eruption of the permanent canine through secondary bone grafts obtained from iliac crest in unilateral alveolar clefts. Eighteen patients (20 clefts) were included in this study; all of them had cleft lip and palate and had been treated with a bone graft before the eruption of the permanent canine. All the patients had a previous radiographic study with orthopantomography, periapical and occlusal radiographies. The mean age was 10.72 years at the time of the surgery. All patients were operated by the same surgeon at the Luis Calvo MacKenna Hospital between the years 2001 and 2005. Each patient had a complete post-surgery photographic and radiographic studies including the same radiographies that were asked before the surgery. The parameters studied were; eruption of the canine, classified as “Erupted” or “Included” (High, Intermediate or Close to the Alveolar Rim), the position of the erupted canine in the arch (palatine, aligned or buccal) and the formation of bone bridge between the maxillary segments. The Chi-Square statistical analysis showed significant differences only for the bone bridge formation, the other parameters did not show significant differences.
