Secondary Alveolar Bone Grafting in Patients Born With Unilateral Cleft Lip and Palate

Abstract

Patients rehabilitated with complex dental restoration seems to be at higher risk for progression of bone loss in the cleft area. Supportive periodontal therapy should be implemented after complex dental restorations in cleft patients. Conventional occlusal radiographs provide an adequate image for evaluating postoperative bone height in clinical follow-up.

Outcome after secondary alveolar bone grafting among patients with cleft lip and palate at 16 years of age: a retrospective study

“…5,8,[17][18][19][20][21] When separating the results for unilateral versus bilateral clefts, our 90% success rate for unilateral clefts is comparable to other reported success rates of 73-94%. 5,9,[17][18][19][20][21] One study by Jabbari et al reported a higher success rate of 98% for unilateral clefts. 8 Those authors used a modified Bergland index to evaluate success, in which Bergland index score II was defined as bone loss of <¾ of the root length, and score III as bone loss of >¾ of the root length.…”

“…Jabbari et al found that the surgical success rate declined when comparing follow-up between 10 and 20 years. 19 In our study, the mean follow-up was 7.2 years, varying from 1.7-10.8 years, and our success rates might decline with a longer follow-up time.…”

“…Poor oral hygiene and gingival bleeding index have previously been reported to correlate with reduced bone height at 10-and 20-year follow-up. 8,19 This finding highlights the impact of local infection on healing, and the importance of maintaining good oral hygiene during bone graft healing, as well as in a long-term perspective to prevent adverse effects on the marginal bone. 22,23 During the study period, in 2003, we changed our method to include the use of a removable retention device, which enabled daily cleaning of the surgical area and thus enhanced the oral hygiene in the operated area.…”

“…This results corresponds to earlier studies of both unilateral and bilateral alveolar bone clefts showing success rates varying between 73-98%. 5,8,9,[17][18][19][20][21] The standard method for evaluating SABG success is to assess the septum bone level according to Bergland's index. 5,8,[17][18][19][20][21] When separating the results for unilateral versus bilateral clefts, our 90% success rate for unilateral clefts is comparable to other reported success rates of 73-94%.…”
