چکیده

BACKGROUND To assess the success of the uptake of bone graft in cleft alveolus of the cleft lip and palate patients, quantitatively through computed tomography (CT) scan 6 months postoperative. To assess the successful eruption of permanent lateral incisor or canine in the bone grafted area. MATERIALS AND METHODS The children age group of 9-21 years with unilateral cleft lip and palate came to the hospital, needing secondary alveolar bone grafting. A detailed history and clinical examination of the patient was taken. A 3D CT scan was taken and the volume of the cleft was measured pre-operatively. After ambulatory period, 3D CT scan of the alveolar cleft region was taken and volume of the bone grafted was measured and patient was discharged from the hospital. After 6 months, patient was recalled and again 3D CT scan was taken and the volume of remaining bone was measured. RESULTS The mean volume of the defect pre-operatively is 0.80 cm(3) with a standard deviation of 0.36 cm(3) with minimum volume of the defect 0.44 cm(3) and maximum volume of the defect 1.60 cm(3). The mean volume of the bone post-operative immediately after grafting is 1.01 cm(3) with a standard deviation of 0.52 cm(3) with minimum of bone volume is 0.48 cm(3) and maximum of 2.06 cm(3). The mean volume of the bone after 6 months after bone grafting is 0.54 cm(3) with a standard deviation of 0.33 cm(3), minimum bone volume of 0.22 cm(3) and maximum bone volume of 1.42 cm(3). CONCLUSION The CT scan is a valuable radiographic imaging modality to assess and follow the clinical outcome of secondary alveolar bone grafting.

Dental implant treatment for a patient with bilateral cleft lip and palate.

Dental reconstruction in the cleft space is difficult in some patients with cleft lip and palate because of oronasal fistulas. Most of these patients receive a particle cancellous bone marrow (PCBM) graft to close the alveolar cleft, and secondary bone grafting is also required. Treatment options for the alveolar cleft including fixed or removable prostheses require the preparation of healthy t...
