Title in English
Canine eruption pathway after alveolar grafting with different materials in patients with complete unilateral cleft lip and palate
Keywords in English
Bone transplantation
Cleft lip
Cleft palate
Abstract in English
The aim of this study was to evaluate the outcome of cleft-permanent canine (CPC) in individuals with complete unilateral cleft lip and palate (CUCLP) submitted to secondary alveolar grafting (SAG) with different materials. Study Design: Retrospective longitudinal study analyzed 120 individuals undergoing alveolar grafting with iliac crest, rhBMP-2 and mandibular symphysis. The individuals were selected at a single center and divided equally into three groups. Panoramic radiographs were analyzed by Dolphin Imaging 11.95 to measure CPC angulation and distance from occlusal plane of the CPC at two different timepoints. Interphases and intergroup comparisons were performed using analysis of variance (p<0,05). Results: No statistical significance was found between grafting materials (P=0.416). At T1, the distance from occlusal plane was greater for rhBMP-2 and mandibular symphysis. Lateral incisor was not related to success or not eruption of CPC (P=0.870). Conclusion: CPC eruption was similar for materials studied. The lateral incisor on the cleft side did not influence the spontaneous eruption of CPCs.

Abstract in Portuguese
O objetivo deste estudo foi avaliar o comportamento do canino permanente (CP) em indivíduos com fissura labiopalatina unilateral completa (FLPC) submetidos a enxerto alveolar secundário (EOAS) com diferentes materiais. Desenho do Estudo: Estudo longitudinal retrospectivo analisou 120 indivíduos submetidos a enxerto alveolar com crista ilíaca, rhBMP-2 e sínfise mandibular. Os indivíduos foram selecionados em um único centro e divididos igualmente em três grupos. Radiografias panorâmicas foram analisadas pelo Software Dolphin Imaging (11.95) para medir a angulação do CP e sua distância em relação ao plano oclusal em dois momentos diferentes. As comparações interfases e intergrupos foram realizadas por meio de análise de variância (P<0,05). Resultados: Não foi encontrada significância estatística entre os materiais de enxertia (P=0,416). Em T1, a distância do CP em relação ao plano oclusal foi maior para rhBMP-2 e sínfise mandibular. O incisivo lateral não foi determinante para a irrupção do CP (P=0,870). Conclusão: A irrupção do CP foi semelhante para os materiais estudados. O incisivo lateral do lado fissurado não influenciou a irrupção espontânea dos CPs.
