Eruption of Impacted Teeth after Alveolar Bone Graft in Cleft Lip and Palate Region

Abstract

This study aimed to assess the eruption of impacted teeth in cleft lip and/or palate (CLP) after alveolar bone graft. Research was carried out through a cross-sectional study at the Craniofacial Rehabilitation Center of the University General Hospital of the University of Cuiaba, Mato Grosso, Brazil. Variables related to cleft, cleft side, gender, age, laterality of cleft, impacted teeth, and orthodontic traction were analyzed. Forty-two patients treated at the institution from 2004 to 2011 were recruited. There were 54.76% males and 45.24% females. The age group between 9 and 11 years was most affected in 59.53% of cases. The unilateral cleft was the most prevalent (85.71%). A total of 57 impacted teeth were observed. Maxillary canine was the most prevalent impacted teeth (97.61%) and more frequent in transforamen incisor cleft (TIC) (76.3%). The orthodontic traction was needed in both maxillary canines and lateral incisor impacted teeth, 64.3 and 35.7% respectively. The orthodontic traction was needed only in TIC (p = 0.0101). The canine teeth were the most prevalent, mainly related to the TIC and all impacted teeth erupted spontaneously in the preforamen incisor cleft (PIC) after placement of the bone graft. There was spontaneous eruption of impacted teeth after secondary alveolar bone graft in CLP.
