Objective: The aim of the present study was to evaluate the transverse effect of rapid maxillary expansion in patients with unilateral complete cleft lip and palate while comparing the Haas and Hyrax appliances. Methods: The sample consisted of 48 patients divided into two groups: Group I - 25 patients treated with modified Haas appliance (mean age: 10 years 8 months); and Group II - 23 patients treated with Hyrax appliance (mean age: 10 years 6 months). Casts were taken during pre-expansion and after removal of the appliance at the end of the retention period. The models were scanned with the aid of the 3 Shape R700 3D scanner. Initial and final transverse distances were measured at cusp tips and cervical-palatal points of maxillary teeth by using the Ortho Analyzer(tm) 3D software. Results: The mean expansion obtained between cusp tips and cervical-palatal points for inter-canine width was 4.80 mm and 4.35 mm with the Haas appliance and 5.91 mm and 5.91 mm with the Hyrax appliance. As for first premolars or first deciduous molars, the values obtained were 6.46 mm and 5.90 mm in the Haas group and 7.11 mm and 6.65 mm in the Hyrax group. With regard to first molars, values were 6.11 mm and 5.24 mm in the Haas group and 7.55 mm and 6.31 mm in the Hyrax group. Conclusion: Rapid maxillary expansion significantly increased the transverse dimensions of the upper dental arch in patients with cleft palate, with no significant differences between the Hass and Hyrax expanders.

This case report demonstrates the successful use of intraoral distractor/hygenic rapid expander (HYRAX) for rapid maxillary expansion in anteroposterior direction with an adjunctive use of face mask therapy for anterior orthopedic traction of maxillary complex in a cleft patient with concave profile. The patient was a 13-year-old girl who reported with a chief complaint of backwardly positioned upper jaw and a severely forward positioned lower jaw. Therefore, a treatment was chosen in which acrylic bonded rapid maxillary expansion was done with tooth tissue borne intraoral distractor/HYRAX having a different activation schedule along with Dr Henri Petit facemask to treat maxillary retrognathism. As a result, crossbite got corrected and attained a positive jet with no bone loss in cleft area over a period of 5 months which was followed by fixed mechanotherapy achieving a well settled occlusion in 1 year. After completion of expansion and fixed mechanotherapy, ANB became +1 post-treatment which was −4 pretreatment. The prognathic profile was markedly improved by expansion and taking advantage of the remaining growth potential, thus minimizing the chances of surgery later in life. This provided a viable alternative to orthognathic surgery with good long-term stability.

ABSTRACT Objective: The aim of this study was to evaluate the skeletal and dental effects of rapid maxillary expansion (RME) in cleft patients using two types of expanders. Methods: Twenty unilateral cleft lip and palate patients were randomly divided into two groups, according to the type of expander used: (I) modified Hyrax and (II) inverted Mini-Hyrax. A pretreatment cone-beam computed tomographic image (T0) was taken as part of the initial orthodontic records and three months after RME, for bone graft planning (T1). Results: In general, there was no significant difference among groups (p > 0.05). Both showed a significant transverse maxillary expansion (p < 0.05) and no significant forward and/or downward movement of the maxilla (p > 0.05). There was greater dental crown than apical expansion. Maxillary posterior expansion tended to be larger than anterior opening (p < 0.05). Cleft and non-cleft sides were symmetrically expanded and there was no difference in dental tipping between both sides (p > 0.05). Conclusions: The appliances tested are effective in the transverse expansion of the maxilla. However, these appliances should be better indicated to cleft cases also presenting posterior transverse discrepancy, since there was greater expansion in the posterior maxillary region than in the anterior one.

A system of differential rapid maxillary expansion is described. This method is particularly useful in patients with cleft lip and palate who have severe defects of lateral maxillary growth, since it enables the maxillary segments to be rotated so that intercanine width increases without a concomitant increase in the intermolar width.

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.

ABSTRACT Objective: The objective of this study was to compare the effects on upper dental arch size and shape after maxillary expansion with Hyrax, Quad-helix, and a differential opening expander in bilateral cleft lip and palate (BCLP) patients. Materials and Methods: Seventy-five BCLP patients were divided into three groups: Hyrax (H), Quad-helix (QH), and Expander with differential opening (EDO). Digital models were obtained before (T1) and after 6 months (T2) of maxillary expansion. Twelve landmarks were placed by one investigator on T1 and T2 dental models of each group, and x,y coordinates for each landmark were collected. For dental arch size analysis, centroid size of each dental arch at T1 and T2 was calculated from raw coordinates and was used as the measure of size. Procrustes Analysis was performed for dental arch shape analysis. Analysis of variance was used to compare the groups for size and shape differences (P &lt; .05). Results: There were no significant dental arch size differences among the expanders at T1 or T2. Differences in arch shape were found between all groups at T2. Intragroup arch shape showed a significant variation for the QH and EDO groups. while it remained stable in the H group. Conclusions: Both the QH and the EDO create dental arch shape changes with greater intercanine than intermolar increase. The H does not change the dental arch shape.
