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.

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.

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.

ABSTRACT This case report presents a 12-year-old boy with unilateral complete cleft lip and palate and severe maxillary retrusion treated with bone-anchored maxillary protraction (BAMP) therapy followed by fixed appliances. The follow-up period extended until the end of growth. Initially, the patient demonstrated a Goslon 4 interarch relationship with an overjet of −3.5 mm and a Wits appraisal of −7.9 mm. Six months after the secondary alveolar bone graft, Bollard miniplates were fixed bilaterally at the infrazygomatic region in the maxilla and between the canines and lateral incisors in the mandible. Class III elastics were used bilaterally full time for 12 months. After treatment, the overjet increased 5.9 mm. Significant maxillary advancement (SNA +3.2°) and skeletal convexity improvement (NA-APo +12.4°) were observed. Retrusion of the anteroposterior position of the mandible was observed (SNB –2.1°). Comprehensive orthodontic treatment was performed after BAMP therapy with nighttime bone-anchored Class III elastics as active retention until the end of growth. Occlusion and facial esthetics were satisfactory at the end of orthodontic treatment and growth. Le Fort I surgery for maxillary advancement was not required. BAMP therapy demonstrated an adequate orthopedic outcome, preventing the need for orthognathic surgery in unilateral complete cleft lip and palate.

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 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.

Orthodontic treatment in patients with orofacial cleft such as cleft lip and palate or isolated cleft palate is challenging, especially when the patients exhibit severe maxillary growth retardation. To correct this deficiency, maxillary expansion and protraction can be performed in the first phase of orthodontic treatment. However, in some cases, the malocclusion cannot be corrected by these procedures, and thus, skeletal discrepancy remains when the patients are adolescents. These remaining problems occasionally require various orthognathic treatments according to the degree of the discrepancy. Here, we describe one case of a female with isolated cleft palate and hand malformation who exhibited severe maxillary deficiency until her adolescence and was treated with multiple orthognathic surgeries, including surgically assisted maxillary expansion (surgically assisted rapid palatal expansion), LeFort I osteotomy, and bilateral sagittal split osteotomy in order to correct severe skeletal discrepancy and malocclusion. The treatment resulted in balanced facial appearance and mutually protected occlusion with good stability. The purpose of this case report is to show the orthodontic treatment outcome of 1 patient who exhibited isolated cleft palate and subsequent severe skeletal deformities and malocclusion which was treated by an orthodontic-surgical approach.

Summary Background The Scandcleft trial is a randomized controlled trial that includes children with unilateral cleft lip and palate where registrations are standardized and therefore provides the opportunity to describe craniofacial characteristics in a very large sample of patients. Objectives The aim of this study was to describe craniofacial growth and morphology in a large study sample of 8-year-old children with unilateral cleft lip and palate (UCLP); before orthodontic treatment and before secondary alveolar bone grafting; and to compare the cephalometric values with age-matched non-cleft children from previous growth studies to identify the differences between untreated cleft- and non-cleft children. Materials There are 429 eight-year-old UCLP patients in the Scandcleft study group. A total of 408 lateral cephalograms with a mean age of 8.1 years were analysed. Cephalometric analyses were performed digitally. The results from three previously published growth studies on non-cleft children were used for comparison. Results Cephalometric analyses showed a large variation in craniofacial morphology among the UCLP group. In general, they present with significant maxillary retrusion and reduced intermaxillary relationships compared to the age-matched non-cleft children. In addition, the vertical jaw relationship was decreased, mainly due to decreased maxillary inclination. The upper and lower incisors were retroclined. It can be expected that these differences will increase in significance as the children age. Conclusion Results from this study provide proposed norms for the young UCLP before any orthodontic treatment and can be valuable for the clinician in future treatment planning. Trial registration ISRCTN29932826.

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.
