Objective This study aimed to review all research evidence of presurgical cleft size and related factors to success of secondary alveolar bone grafting (SABG). Design and Setting The systematic review searched the OVID-Medline®, PubMed®, Embase®, and Cochrane Central Register of Controlled Trials (CENTRAL) up to August 2020. Two reviewers independently selected potential abstracts for full review. Disagreeements were resolved by consensus. The first author extracted data and assessed the risk of bias using Risk of Bias in Non-randomized studies—of Interventions tool. Patients and Interventions Patients with non-syndromic clefts who received SABG were selected. Presurgical cleft size/volume and treatment results must be available. Main Outcome Measures Level of the grafted bone, achievement of orthodontic tooth movement into the grafted area, need for re-operation. Results From 962 abstracts, 23 publications were included. Mean cleft width was 6.80 ± 1.98 mm, cleft area 20–240 mm2, and mean volume 0.89 ± 0.33 cm3. No definite conclusion was achieved on whether a narrow or wide cleft showed better treatment outcomes, but other potentially related factors were good oral hygiene and eruptive force of the maxillary canines. Lack of a standard definition of cleft size, a small sample size, varying outcome parameters, and moderate-to-high risk of bias contributed to the summary. A meta-analysis could not be performed because of the heterogeneity. Conclusion Due to insufficient evidence, cleft width/volume could not be specified leading to more successful SABG. Care of patients could be improved in both research by following rigorous methodology, and practice by clear communication.

ABSTRACT Objectives: To measure the root lengths of maxillary central incisors (U1) and evaluate the relationship among U1 root length, tooth movement, and type of treatment appliance in patients with unilateral cleft lip and palate over a long-term follow-up period. Materials and Methods: Occlusal radiographs of 30 patients with unilateral cleft lip and palate, acquired less than 6 months before secondary alveolar bone grafting (SBG, T1) and after edgewise treatment (T2), were measured for U1 root length (R1 and R2, root lengths at T1 and T2, respectively). Frontal and lateral cephalometric radiographs acquired at eruption of U1 (T0), T1, and T2 were evaluated to determine the inclination and position of U1. Results: The average values of R1 and R2 on the cleft side were significantly lower than those on the noncleft side. Frontal cephalometric analysis revealed that the horizontal distance of the root apex from the median vertical line at T0 on the cleft side was significantly smaller than that on the noncleft side and was correlated with short U1 root length on the cleft side. On the other hand, R1 in patients treated with maxillary protraction appliances between T0 and T1 was significantly shorter than that in patients without maxillary protraction appliances. However, none of the changes in cephalometric measurements were correlated with root length. Conclusions: In patients with unilateral cleft lip and palate, the short root length of cleft-adjacent central incisors might be associated with the horizontal position of the root apex. In addition, orthodontic treatment with a maxillary protraction appliance before secondary alveolar bone grafting might be associated with short U1 root length.

Abstract There are controversies related to the effects of bone grafts on tooth eruption and impaction in patients with cleft lip and palate. The aim of this systematic review was to evaluate the effectiveness of bone grafting on eruption of canines in patients with unilateral cleft lip and palate (UCLP). An electronic search was conducted in six electronic databases and gray literature, without limitations on year of publication or language. The primary outcome was the increase in rate of canine eruption; the secondary outcomes were success of the bone graft, canine impaction due to agenesis of the lateral incisor, and effect of orthodontic treatment before and after bone grafting. The risk of bias was analyzed by means of the tool Cochrane risk of bias in nonrandomized controlled trials (NRCTs) of interventions (ROBINS-I). The certainty of the evidence was assessed for outcomes reported through a narrative synthesis using grading of recommendations, assessment, development and evaluation (GRADE) approach. Four NRCTs were included, with a total of 360 patients, 283 UCLP and 77 bilateral cleft lip and palate (BCLP). The studies reported association between the increase in the rate of tooth eruption and bone graft with very low certainty of evidence, and greater experience of surgical success, with low certainty of evidence. The majority of the studies found an association between increase in the rate of canine impaction and agenesis of the lateral incisor, with very low certainty of evidence. There was very low certainty of the efficacy of secondary alveolar bone grafting for increasing the rates of eruption and reducing impaction of the maxillary canine.

Objective This paper introduces a surgical technique for premaxillary repositioning in combination with two-stage alveolar bone grafting for the correction of the premaxillary deformity of patients with bilateral cleft lip and palate (BCLP). The paper also reports on two patients with BCLP who underwent this surgical management. Surgical Procedure The operation is usually performed when the patient is 8 to 14 years of age. In the first stage of surgery, the side more accessible to the septopremaxillary junction is selected, and an osteotomy of the premaxilla and unilateral alveolar bone grafting are performed. Approximately 4 to 12 months after the first stage of surgery, contralateral alveolar bone grafting is carried out. Conclusion We have found that this surgical procedure is highly effective, because it ensures the blood supply to the premaxilla and minimizes the potential for surgical failure. Moreover, it affords wide exposure of the premaxillary bone surface, facilitating sufficient boney bridging and allowing for orthodontic tooth movement.
