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.

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: The objective of this retrospective longitudinal study was to evaluate short- and long-term results of the application of the Liou Alt-RAMEC (alternate rapid maxillary expansion and constriction) technique, a late orthopedic maxillary protraction technique, with intraoral anchorage, in patients with cleft. Materials and Methods: Twenty-six patients with unilateral cleft lip and palate (UCLP) were consecutively treated with the Alt-RAMEC technique. The average age of the patients was 11.7 years (10.3-13.2 years) before protraction and 18.3 years (17.4-21.1 years) at long-term follow-up. A sample of nontreated patients with UCLP was used as a control group. It was matched for sex, skeletal class III, and age (11.3 years). The control sample had records at the end of growth (18.7 years). Results: The sagittal advancement of A-point, after the application of the technique, was 5.7 (2.17) mm. Some mandibular dentoalveolar and positional adaptation was noted. The position of the maxilla was stable in the long term. On the other hand, the UCLP control group showed hardly any growth at the maxillary level during the long-term follow-up period. Conclusion: Our results showed that the Alt-RAMEC technique, performed at the correct time, with a double-hinged expander, followed by class III spring or elastic traction, 24 hours per day, allows for satisfactory maxillary protraction, with, at this stage, apparently stable long-term results. Nevertheless, as only 50% of the patients had long-term follow-up data, we are still unable to predict the percentage of patients which will not eventually need orthognathic surgery.

ABSTRACT Objectives: This study evaluated the long-term stability of maxillary protraction (MP) in patients with complete unilateral cleft lip and palate (UCLP) and identified factors influencing relapse and long-term outcomes. Materials and Methods: Twenty-three adolescents with UCLP who underwent MP therapy were recalled when craniofacial growth was close to completion. Subjects exhibiting reverse/positive overjets were assigned to unstable/stable groups. Lateral cephalometric measurements were made before treatment (T0), after active treatment (T1), and at the end of the growth spurt (T2). Results: About 63% of the subjects exhibited positive overjets during follow-up. The unstable group demonstrated higher B–x and Co–Gn distances than the stable group (both P < .05) at T0. More short-term (T0–T1) sagittal advancement of point A (A–y) was evident in the unstable group than in the stable group (P < .05), but no long-term difference was apparent between the two groups (P = .481). During the posttreatment period (T1–T2), the SNA angle and maxillary incisor protrusion (U1–SN angle) were considerably lower in the unstable group than in the stable group (both P < .05). Overall, the unstable group exhibited a lower increase in the vertical extent of point A (A–x) than the stable group from T0 to T2 (P < .05). Conclusions: In the long term, MP affords favorable maxillary advancement in patients with UCLP. A mandibular excess at T0 and vertical maxillary hypoplasia may contribute to the long-term relapse of a reverse overjet.

Abstract Objectives The aim of this study was to evaluate the cephalometric outcome of bone- anchored maxillary protraction (BAMP) in individuals with unilateral complete cleft lip and palate (UCLP). Material and methods The experimental group (EG) comprised 23 individuals (17 males and 6 females) with UCLP and a mean age of 11.7 years. At least 6 months after secondary alveolar bone grafting, Bollard miniplates were installed in the posterior region of the maxilla and in the anterior region of the mandible. Class III elastics were recommended to be worn for 24 hours/day for a mean time of 18 months. Cone beam computed tomography (CBCT) was obtained before (T1) and after treatment (T2). The control group (CG) consisted of 23 individuals with UCLP matched by initial age and gender with the EG and without any orthopaedic or surgical intervention performed between T1 and T2. The interval between T1 and T2 observations was 18 months for both groups. Twenty-one cephalometric variables were analysed. Intra- and intergroup comparisons were performed using paired and independent t-tests, respectively (P < 0.05). Results BAMP caused a greater maxillary protrusion (SNA) and a greater decrease of Class III maxillomandibular discrepancy (ANB and Wits appraisal) compared with the CG. BAMP also caused a counterclockwise rotation of the occlusal plane (Occ Plane to FH) and an improvement in the molar relationship compared with controls. Conclusions BAMP therapy demonstrated a significant orthopaedic maxillary protraction and an improvement in the Class III skeletal pattern in UCLP.

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.

ABSTRACT Objectives To assess the effectiveness of bone-anchored maxillary protraction (BAMP) in patients with unilateral cleft lip and palate (UCLP) and whether it was enhanced when preceded by maxillary expansion. Materials and Methods The sample consisted of 28 growing children (9–13 years old) with UCLP and Class III malocclusion. They were divided into two equal groups. In group I, patients were treated with BAMP not preceded by maxillary expansion. In group II, patients were treated with BAMP preceded by maxillary expansion. To assess treatment changes in three dimensions, Cone-beam computed tomography images were taken 1 week after surgical placement of the miniplates (T1) and after 9 months of treatment (T2). Results BAMP produced forward movement of the maxilla in both groups (3.17 mm) and (3.37 mm) respectively, without significant differences between the two groups except for clockwise rotation of the palatal plane in group I (1.60). Conclusions BAMP is an effective treatment modality for correcting midface deficiency in patients with UCLP whether or not maxillary expansion was carried out.

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.

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.
