Abstract: | The purpose of this investigation is to determine whether primary alveolar cleft bone grafting in infants with unilateral cleft lip and palate (N = 17) leads to less favorable dental arch dimensions at age 8 when compared with other 8-year-old patients with unilateral cleft lip and palate who received no alveolar bone grafting procedures (N = 49). Dental casts were obtained for the primary grafted group, and arch lengths and widths were digitally recorded with a reflex microscope. These arch dimensions were then compared with the reported data for a nongrafted group and a noncleft group of 8-year-old children. The major findings were: 1) that the dental arches of both cleft groups generally demonstrated a significant diminution in length and width (P < 0.05) compared with the noncleft groups, and 2) that the patients who underwent primary alveolar cleft bone grafting showed no statistically significant difference for any arch dimension (P < 0.05) when compared with the nongrafted group lacking this additional surgical procedure. |
