Objective To verify the effects of rapid maxillary expansion performed after secondary alveolar bone graft in one patient. Setting Department of Orthodontics of the Hospital for Rehabilitation of Craniofacial Anomalies, University of Sao Paulo. Patient(s) The patient had bilateral cleft lip and palate, had already had a bone graft, and showed a relapsing maxillary constriction in need of correction. Intervention A fixed dental-mucous-bone-supported expander corrected the maxillary constriction. Main Outcome Measure(s) Measurements were obtained from dental casts, including transverse dimensions (intercanine distance [IC], interfirst premolar distance [IP], and interfirst molar distance [IM]) and measurements of the grafted area (interfirst premolar/central incisors [IPI] and interfirst premolar/canine [IPC]) to observe the changes. Clinical and radiographic analyses were done through direct view. Results The occlusal radiograph of the maxilla after expansion showed opening of the intermaxillary suture in the premaxillary area, which was clinically confirmed by the diastema between the maxillary central incisors. No radiographic alteration was observed in the grafted area. The transverse measurements of the dental casts (IC, IP, and IM) showed a significant increase. The measurements of the teeth adjacent to the grafted area, IPI and IPC, increased. Conclusions The orthopedic effect of rapid maxillary expansion after bone graft was verified. Nevertheless, additional studies are necessary to define any side effects in patients submitted to bone graft.

This study aimed to analyze the effectiveness of the closure of oronasal communication, to report the importance of secondary alveolar bone graft repositioning of the premaxilla in patients with bilateral complete cleft lip and palate. Material and methods: This retrospective study analyzed the medical records obtained from the Cleft Lip and Palate Integral Care Center/ Association of Rehabilitation and Social Development of Cleft Lip and Palate Patients (CAIF/AFISSUR), Curitiba – Paraná – Brazil, to obtain statistical data involving 26 records of patients who underwent this surgery in the period between January/2010 – January/2014. Results and Conclusion: The benefits observed were: premaxilla stability, aided by the union of pre-maxillary segments; integrity of oronasal structure; aesthetic improvement; better bone support for the teeth adjacent to the cleft; support for the bridge of the nose reducing facial asymmetry and facilitating future rhinoplasty; orthodontic treatment without the limitation of the bone defect; closure of oronasal communication in 88% of patients.

The aim of this study was to measure and compare the dimensions of the dental arches on three-dimensional digital study models in children with and without cleft lip and palate before the primary surgery. The sample consisted of 223 digital models of children aged 3-9 months, divided into 5 groups: without craniofacial deformities, unilateral and bilateral incomplete cleft lip and alveolus, unilateral and bilateral complete cleft lip and alveolus, unilateral cleft lip and palate, and bilateral cleft lip and palate. Dental casts of the maxillary dental arches of the children were used. The dental casts underwent a process of scanning through 3D scanner and the measurements used for the correlation among groups were made on the scanned images. Statistical analysis was performed by t test and ANOVA followed by Tukey test. The results showed that the intercanine distance and anterior cleft width was wider in children with unilateral cleft lip and palate. The intertuberosity distances and posterior cleft width was wider in children with bilateral cleft lip and palate among the groups. Children with cleft lip and palate before the primary surgery had wider maxillary arch dimensions than the children without cleft lip and palate.

Objective To investigate biomechanical effects of cleft type (unilateral/bilateral cleft lip and palate), facemask anchorage method (tooth-borne and miniplate anchorage), and alveolar bone graft on maxillary protraction. Design Three-dimensional finite element analysis with application of orthopedic force (30° downward and forward to the occlusal plane, 500 g per side). Model Computed tomography data from a 13.5-year-old girl with maxillary hypoplasia. Intervention Eight three-dimensional finite element models were fabricated according to cleft type, facemask anchorage method, and alveolar bone graft. Main Outcome Measure(s) Initial stress distribution and displacement after force application were analyzed. Results Unilateral cleft lip and palate showed an asymmetric pattern in stress distribution and displacement before alveolar bone graft and demonstrated a symmetric pattern after alveolar bone graft. However, bilateral cleft lip and palate showed symmetric patterns in stress distribution and displacement before and after alveolar bone graft. In both cleft types, the graft extended the stress distribution area laterally beyond the infraorbital foramen. For both unilateral and bilateral cleft lip and palate, a facemask with a tooth-borne anchorage showed a dentoalveolar effect with prominent stress distribution and displacement on the upper canine point. In contrast, a facemask with miniplate anchorage exhibited an orthopedic effect with more favorable stress distribution and displacement on the middle maxilla point. In addition, the facemask with a miniplate anchorage showed a larger stress distribution area and suturai stress values than did the facemask with a tooth-borne anchorage. The pterygopalatine and zygomatico-maxillary sutures showed the largest suturai stress values with a facemask with a miniplate anchorage and after alveolar bone grafting, respectively. Conclusion In this three-dimensional finite element analysis, it would be more advantageous to perform maxillary protraction using a facemask with a miniplate anchorage than a facemask with a tooth-borne anchorage and after alveolar bone graft rather than before alveolar bone graft, regardless of cleft type.

Objective: To evaluate the efficacy of rapid maxillary expansion (RME) and maxillary protraction (MP) in patients with unilateral complete cleft lip and palate (UCLP) using the Goslon yardstick index. Design: Retrospective study. Patients: Dental casts of 34 Goslon 3 (G3) and Goslon 4 (G4) patients treated with RME and MP were evaluated which composed the treated sample (S1). The dental cast were taken before the RME (T1) and immediately after the use of face mask for MP was suspended (T2). In order to verify the stability of the treatment, dental casts of 17 of these patients were evaluated 1 year after the treatment was finished (T3). For the control sample (S2), dental casts of 20 untreated G3 and G4 patients were evaluated. Results: At T2, 85.7% of study sample patients initially G3 and 70% of patients initially G4 obtained improvement in occlusal index. At T3, the majority of patients initially classified as G3 and G4 returned to the same classification as in the beginning of the treatment. The evaluation of the control sample showed that patients initially classified as G3, 55.6% continued at this initial index, and 44.4% had it worsened. Those initially G4, 100%, continued at this initial index. Conclusion: The immediate result of RME and MP was satisfactory, and despite the instability of these results, the outcome of this treatment option was better than the untreated sample.
