Objective The objective of this study was to test a new method, a Standardized Way to Assess Grafts (SWAG), to rate alveolar bone graft (ABG) outcomes for patients with cleft lip and palate. Design This was a retrospective comparison using the SWAG scale. Setting This study took place in four cleft palate centers with different treatment protocols. Methods A total of 160 maxillary occlusal radiographs taken 3 to 18 months post-ABG for sequentially treated patients with cleft lip and palate were assessed using the SWAG scale. Radiographs were scanned, standardized, blinded, and rated by 6 calibrated orthodontists to assess vertical thirds, bony root coverage, and complete bony fill. All radiographs were rated twice, 24 hours apart, by the same raters. Main Outcomes Intra- and interrater reliabilities were assessed. Results Intrarater reliability was good to very good (.760; .652–.834), and interrater reliability was moderate to good (.606; .569–.681), comparable to previously published methods. Conclusions Rater reliabilities were shown to be comparable to or better than existing methods. The SWAG method was validated for ABG assessments in the mixed and permanent dentitions based on reliabilities in an intercenter outcome comparison.

Secondary Alveolar Bone Grafting

Cleft lip and palate is one of the most common facial deformities. During embryonic life, non-fusion of the maxillary and medial nasal plaques leads to cleft lip and palate. Fissures can produce a range of dental problems in terms of number, size, shape, and position, related to deciduous or permanent dentition. Besides this, the teeth most affected are those located in the fissure area. There are numerous treatment protocols, which, despite the lack of a consensus, start as soon as the child is born, going into adulthood, seeking functional and aesthetic rehabilitation. The surgical phases, lip repair, nasal repair, palatoplasty and alveolar bone grafting, are performed according to age. As for the bone graft, the most used option is the secondary graft, with the autogenous one being the most available. Thus, the objective of this work is to present a clinical case of secondary alveolar bone grafting in a 10-year-old female patient with an incomplete unilateral pre-foramen cleft.

Matching Criteria

The purpose of this study was to describe and compare posttreatment craniofacial morphology in samples of complete unilateral cleft lip and palate (CUCLP) patients treated at two leading clinics: The Children's Memorial Hospital Cleft Palate Clinic, Chicago, Illinois, and the Lancaster Cleft Palate Clinic, Lancaster, Pennsylvania. These centers have well-defined treatment protocols that allow the long-term effects on craniofacial form of the following treatment regimes to be contrasted: (1) Chicago—primary alveolar bone grafting, with definitive lip repair at age 4 to 6 months and hard and soft palate repair at 6 to 12 months; and (2) Lancaster—definitive triangular-flap lip repair at 3 months of age, followed by staged surgeries of the hard and soft palates, both completed by 18 months of age, but without primary alveolar bone grafting. Although the Lancaster center now performs secondary alveolar bone grafting, the majority of the patients studied here were treated before this procedure became part of their protocol. Patients were eligible for inclusion if they had no other congenital anomalies and no previous orthodontic treatment. A sample of 43 (24 male, 19 female) CUCLP patients was obtained from the Chicago Center, each of which was then matched to a non-grafted Lancaster CUCLP patient. The matching criteria were age, sex, and sella-nasion distance (to control, at least in part, for size differences). Lateral cephalometric radiographs of these 86 CUCLP patients were traced, digitized, and analyzed. Additionally, all linear data were adjusted to a standard magnification of 8% because the cephalograms from each center featured different enlargements. The Chicago and Lancaster samples had mean posttreatment ages of 10.32 years (SD = 1.96) and 10.40 years (SD = 2.18), respectively. The grafted Chicago group had faces that were on average less maxillary protrusive compared with the nongrafted Lancaster sample; it appeared, however, that the mandible compensated for the maxillary position by downward and backward rotation. As a result, a similar maxillomandibular relationship was noted in both groups, although, in the Chicago group, the lower anterior facial height increased.

Objective: To determine the rate of revision alveolar bone grafting (ABG) in patients with cleft lip and palate (CLP) before and after the introduction of postoperative computed tomography (CT). Design: Retrospective case–control study analyzing the incidence of revision ABG in patients with and without postoperative CT scans for graft success evaluation. Setting: Academic tertiary care pediatric hospital. Patients: Eighty-seven patients with CLP or cleft lip and alveolus treated with autologous iliac crest bone grafting for alveolar clefts over a 10-year period (January 2009 to March 2019) with minimum 6-month follow-up. Fifty patients had postoperative CT evaluation; 37 did not. Interventions: Postoperative CT to determine ABG success, versus standard clinical examination and 2-dimensional radiographs. Main Outcome Measures: Requirement for revision ABG, defined as failure of the original graft by clinical or radiographic examination. Results: Fifty-eight percent of patients underwent a postoperative CT scan at median interval of 10 months after surgery. Patients with postoperative CT evaluation had a 44% rate of revision ABG (22/50) for inadequate graft take, compared to 5% (2/37) in patients without postoperative CT ( P < .001; 95% CT, 31%-58% in the CT group, 1%-16% in the non-CT group). Conclusions: Computed tomography evaluation after ABG is associated with a significantly increased revision rate for inadequate graft take. The presence of a secondary palatal fistula at the time of original ABG is not associated with revision requirement. Lack of standardized dental and orthodontic records complicates the study of ABG outcomes and presents an area for systems-based improvement.

Abstract Purpose The aims of this retrospective cross-sectional study were to measure and compare labial and palatal alveolar bone heights of maxillary central incisors in unilateral cleft lip and palate patients, following STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. Patients and methods The study group consisted of 21 patients with a mean age of 16 years. High-resolution cone-beam computed tomography was performed at least one year after secondary alveolar bone grafting. The experimental side was the cleft side and the contralateral side without congenital cleft was the control. Measurements were performed on incisors’ midsagittal cross-sections. The Wilcoxon signed-rank test was used for intergroup comparisons. Results The labial and palatal distances between alveolar bone crests and cementoenamel junctions were significantly greater on the cleft side than on the noncleft side. Mean differences were 0.75 and 1.41 mm, respectively. The prevalence of dehiscences at the cleft side maxillary central incisors was 52% on the labial surface and 43% on the palatal surface. In the controls, it was 19% and 14%, respectively. Conclusion The cleft-adjacent maxillary central incisors had more apically displaced alveolar bone crests on the labial and palatal sides of the roots than the controls. Higher prevalence of dehiscences was found on the cleft side. Bone margin differences predispose to gingival height differences of the central incisors. These differences could increase the demands of patients to obtain more esthetic treatment results with orthodontic extrusion and periodontal intervention on the cleft side.

Objective The purpose of this study was to evaluate an ultrasound mucous-membrane-thickness-measuring device as a noninvasive, nonionizing alternative to radiography in the assessment of alveolar bone grafting. Design This was a prospective experimental study on porcine cadaver models. Method An ultrasound technique (Krupp SDM) was assessed ex vivo on three specially developed porcine cadaver models in comparison to radiography and ridge-mapping. Direct measurement of the mucosal thickness provided a standard for comparison. In each model, 30 measurement sites were identified for comparison of the techniques. Results All measurement techniques demonstrated clinically acceptable re-producibility. Of the clinical measurement techniques, radiography proved to be the most reliable, showing a small, nonsignificant statistical difference from direct measurement. Both the ultrasound technique and ridge-mapping showed significant tendencies to underestimate mucosal thickness that became greater with increasing mucosal thickness. At sites where mucosal thickness was less than 6 mm, the ultrasound technique underestimated mucosal thickness by 0.6 mm on average. At sites where mucosal thickness exceeded 6 mm, ultrasonic artifacts rendered the ultrasound technique unreliable. Conclusion The ultrasound technique could prove to be a useful clinical adjunct to radiography in the assessment of alveolar bone grafts, but in this particular application, care should be taken when using it to assess deeper alveolar defects.

ABSTRACT Objectives: To describe qualitatively and quantitatively the directions and magnitudes of rotations of permanent maxillary central incisors and first molars in the mixed dentition in repaired complete unilateral cleft lip and palate (UCLP) and study their associations with absence of teeth in their vicinity. Materials and Methods: Dental casts and orthodontic records taken prior to orthodontic preparation for alveolar bone grafting of 74 children with repaired UCLP (53 male, 21 female; aged 8.9 ± 1.0 years) were studied. Directions and magnitudes of permanent maxillary central incisor and first molar rotations were recorded. Tooth absence was confirmed from longitudinal radiographic records. Incisor and molar rotations were analyzed in relation to the absence of teeth in their vicinity. Results: Distolabial rotation of the permanent maxillary central incisor was noted in 77.14% on the cleft side, while distopalatal rotation was noted in 82.19% on the noncleft side. Incisor rotation was greater when a permanent tooth was present distal to the cleft side central incisor, in the greater segment. The permanent maxillary first molar showed mesiopalatal rotation, which was greater on the cleft side and when there was absence of one or more teeth in the buccal segment. Conclusions: Presence and absence of teeth were associated with the severity of incisor and molar rotations in UCLP. Crowding of anterior teeth in the greater segment was associated with a greater magnitude of rotation of the cleft side permanent central incisor. Absence of one or more buccal segment teeth was associated with greater magnitude of rotation of the molar.

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.
