LEITE, Thiago Bomfim; BEZERRA, Bruno Torres  e  SILVA, Luiz Carlos Ferreira da. Volumetric Measurement of Alveolar Cleft. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2014, vol.14, n.2, pp.103-108. ISSN 1808-5210.

Objectives: The purpose of this study was to evaluate the alveolar cleft in individuals with cleft lip and palate,and measure its volumetric dimensions, describe the topography of the defect and assess periodontal bone support of teeth adjacent to the cleft. Methods: 16 patients between 11 and 30 years old were selected for volumetric evaluation of alveolar cleft. All measurements were made of cement-enamel junction to the bone structure location. The slice thickness of the images of cone beam computed tomography was 0.25mm. The delineation of the defect was done by a single operator. Results: The mean volume of the clefts was 1.13 cm3 ± 0.35 cm3. There were no statistical significance between the volume of the cleft and the ages of the patients, nor between the volume of the cleft and the presence/absence of the lateral incisor. Conclusion: Through the cone beam computed tomography and its 3D reconstructions is possible to visualize the entire length and depth of the cleft, facilitating surgical planning of bone transplantation.
