Objective: To determine whether there is any correlation between initial maxillary arch dysmorphology patterns in complete bilateral cleft lip/palate (BCLP) and the subsequent occlusal relationship in early mixed dentition. Design: This retrospective study evaluated 41 consecutive patients with complete BCLP who were managed by a single tertiary cleft team between 1983 and 1992. All patients had bilateral synchronous lip adhesions with placement of a passive alveolar molding appliance at 4 to 8 weeks of age; definitive modified Manchester lip repair at 6 to 8 months of age; and a one-stage “two-flap” palatoplasty at 14 months of age. Neither gingivoperiosteoplasty nor early alveolar bone grafting was performed. Four patients required early surgical premaxillary setback because of adverse social reactions to a very protrusive premaxilla. All patients (7 to 9 years) were assessed prior to initiation of first-phase orthodontics (maxillary expansion) in anticipation of alveolar bone grafting. Cleft team records were reviewed to determine initial maxillary arch dysmorphology, treatment, and occlusal relationships in early mixed dentition stage. The initial maxillary dysmorphology was classified using a new grouping based on orientation of the vomer, the intercanine distance, and its symmetry. Patterns of mixed dentition occlusion were then compared with group type, and predication tables were generated. Because midface retrusion is the major dentoskeletal morbidity in cleft patients, angle Class I and II occlusions were designated as “favorable” and Class III as “unfavorable.” Results: In early mixed dentition, approximately three-fourths of patients with complete BCLP had favorable occlusion and one-fourth unfavorable occlusion. The occlusal status seemed unrelated to the initial maxillary arch dysmorphology, the use of early passive alveolar molding appliance, or surgical premaxillary setback. Conclusion: Patterns of variation within the initial dysmorphology of the maxillary arch in infants with complete BCLP cannot be used to predetermine subsequent molar occlusal relationships in the mixed dentition.

The purpose of this study was to report a case with complete unilateral cleft lip and palate (CLP) treated with bone anchored maxillary protraction (BAMP) in miniplates followed up until the end of facial growth. A 7-year-old girl with complete left side CLP started the orthodontic treatment in a rehabilitation center. She presented a Class III skeletal pattern due to maxillary deficiency, a GOSLON 4 sagittal interarch relationship, a negative overjet of 1.5mm and agenesis of left upper lateral incisor. In the mixed dentition, the patient was submitted to rapid maxillary expansion followed by the secondary alveolar bone grafting procedure. At 12y 3m two miniplates were installed in the maxilla and two in the mandible with BAMP therapy. The patient was instructed to use full time Class III elastics with force of 250g/side together with a bite lifting plate in the upper arch. BAMP therapy duration was 19 months leading to a positive overjet and GOSLON 1 sagittal interarch relationship. The cephalometric analysis demonstrated a mild maxilla advancement. Class III elastics started to be used only at night as an active retention concomitantly with Phase II orthodontic treatment. Compensatory corrective orthodontic treatment established adequate occlusion between the dental arches with significant improvement of facial aesthetics after the intervention. Le Fort 1 surgery with maxillary advancement was not necessary.

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.

Objective To determine if secondary alveolar bone grafting (SABG) timing in patients with cleft lip and palate (CLP) influences the future need for additional maxillary advancement procedures, particularly Le Fort I osteotomy with rigid external distraction (RED). Design Retrospective cohort study. Groups were separated by SABG timing: early mixed dentition (ages 68 years) or late mixed dentition (ages 9-11 years). The criterion for RED was negative overjet ≥8 mm, and sufficient dental development for RED. Setting Single tertiary care institution. Patients Patients with CLP that underwent SABG from 2010 to 2015. Exclusion criteria included syndromic conditions, SABG surgery at age >12 years, current age <12 years, and <2 years follow-up. 104 patients were included. Main outcome measures The number of RED candidates and treated patients. Results There was no statistical difference in the number of RED candidates ( P  =  .0718) nor treated patients ( P  =  .2716) based on SABG timing; stratification by laterality was also insignificant. Early SABG is associated with higher odds of being a RED candidate (pooled, unilateral, bilateral) and treated patient (pooled and unilateral); however, there were no statistically significant associations between SABG timing and the number of RED candidates and treated patients as determined by logistic regression models. Conclusion There is no statistically significant association between SABG timing and the odds of being a RED candidate or treated patient. Future prospective studies are recommended to assess the relationship between SABG timing and maxillary growth in patients with CLP.

Secondary Alveolar Bone Grafting

Secondary alveolar bone grafting (SABG) is associated with donor site morbidities. We aimed to compare the outcomes of SABG and extensive gingivoperiosteoplasty (EGPP) at the mixed dentition stage. This single-blinded, randomized, prospective trial enrolled 50 consecutive patients with unilateral complete cleft lip and palate who had residual alveolar bone cleft, of which 44 (19 SABG, 25 EGPP) completed the study. Bone volumes before surgery, 6 months postoperatively, and 1-year postoperatively were compared using computed tomography. The Bergland scale score was recorded at 6 months postoperatively. Both groups had the same preoperative alveolar cleft volume. On the Bergland scale, 21, 3, and 1 patient in the EGPP group and 16, 2, and 1 patient in the SABG group were classified as types I, II, and IV, respectively, which did not show significant difference. With perioperative orthodontic treatment, the 1-year residual bone defect volume in both groups did not show significant difference (SABG 0.12 cm3 vs. EGPP at 0.14 cm3, p > 0.05). The study was not able to reveal much difference between SABG and EGPP combined with perioperative orthodontic treatment.

Cleft Lip Repair

Alveolar bone grafting plays a crucial role in cleft reconstruction. When neonatal presurgical orthodontia is successful in aligning the cleft segments, alveolar reconstruction can be initiated as a gingivoperiosteoplasty during primary cleft lip repair. In children with cleft palate, alveolar bone grafting is usually done after transverse maxillary expansion with a palatal expander. Exact timing of bone grafting is controversial; most centers initiate orthodontic evaluation/expansion between ages 7 and 8 years (beginning of mixed dentition) with an aim to bone graft before age 10 in order to allow osteogenic incorporation prior to eruption of the permanent canine teeth.

Objective: To assess the radiographic outcome of secondary alveolar bone grafting in individuals with nonsyndromic unilateral or bilateral cleft lip and palate using cone beam computed tomography. Methods: This prospective study was conducted at the University of California at San Francisco Center for Craniofacial Anomalies on 21 consecutive nonsyndromic complete cleft lip and palate individuals between 8 and 12 years of age who required alveolar bone grafting. Seventeen unilateral and four bilateral cleft lip and palate individuals had preoperative and postoperative cone beam computed tomography scans that were analyzed using Amira 3.1.1 software. Results: The average volume of the preoperative alveolar cleft defect in unilateral cleft lip and palate was 0.61 cm3, and the combined average volume of the right and left alveolar cleft defects in bilateral cleft lip and palate was 0.82 cm3. The average percentage bone fill in both unilateral cleft lip and palate and bilateral cleft lip and palate was 84%. The outcome of alveolar bone grafting was assessed in relation to (1) type of cleft, (2) size of preoperative cleft defect, (3) presence or absence of lateral incisor, (4) root development stage of the maxillary canine on the cleft side, (5) timing, and (6) surgeon. None of these parameters significantly influenced the radiographic outcome of alveolar bone grafting. Conclusions: Secondary alveolar bone grafting of the cleft defect in our center was successful, based on radiographic outcome using cone beam computed tomography scans. Volume rendering using cone beam computed tomography and Amira software is a reproducible and practical method to assess the preoperative alveolar cleft volume and the adequacy of bone fill postoperatively.
