Abstract Objective: To evaluate the transverse stability of the dental arch in unilateral cleft lip and palate (UCLP) patients after orthodontic treatment with quadhelix and edgewise appliances. Materials and Methods: Twenty repaired complete UCLP patients with posterior crossbites were chosen as the study subjects. All had ceased retention at least 15 months previously. Measurements were carried out directly on the pretreatment, posttreatment, and postretention study models using a three-dimensional dental cast analyzer. The interdental widths were measured for the canines, first premolars, second premolars, first molars, basal bone, and the alveolar arch. Two-way analysis of variance and Fisher's LSD was performed in comparing the difference between intervals. Results: Lower inter-first-premolar width and upper arch widths of each region increased significantly (P < .05) after orthodontic treatment. The expansion was greater in the anterior than the posterior region in the upper arch, and the greatest increase was in the upper first premolar region. The upper arch width decreased after retention, with the decrease of the arch width in the upper canine (1.3 ± 0.8 mm) and first premolar (1.5 ± 0.8 mm) regions being statistically significant. The increased upper arch width in each region and the lower inter-first-premolar width maintained significant expansion after retention. Conclusions: The widths of the dental arch increased significantly after expansion with a quadhelix followed by preadjusted edgewise treatment. Relapse occurred, especially in the upper canine and first premolar region, but most of the treatment effect on the upper arch remained after retention.

Objective: To evaluate the dental arch relationships of Japanese children with complete unilateral cleft lip and palate (UCLP) and to examine the 5-year-olds’ index for its validity. Design: Retrospective study and comparison with previous reports. Subjects: One hundred thirty-six children with complete UCLP who received primary cheiloplasty and palatoplasty in the Kyushu University Hospital from 1966 to 1999. Materials: Dental models taken from children 53 to 67 months of age and their cephalograms. Methods: Study models were assessed using five scores; 1 = excellent, 2 = good, 3 = fair, 4 = poor, and 5 = very poor, in accordance with the 5-year-olds’ index and also evaluated using Huddart and Bodenham's numerical classification. Dental arch widths, three-dimensional maxillary dental arch form, and lateral cephalograms were traced and measured. The outcome by 5-year-olds’ index was compared with Huddart and Bodenham's numerical classification, dental arch dimensions, and cephalometric measurements. Results: Occlusal outcome evaluated by the 5-year-olds’ index was rated 2.95, which was classified as fair. This index rating showed a significant relationship with numerical classification and dental arch length, but not with dental arch width. The index showed a relationship with mandibular form and position, but not with maxillary position. Conclusion: The occlusal outcome of the cases with UCLP was fair as evaluated using the 5-year-olds’ index. The index evaluates the anteroposterior relationship of maxillary/mandibular dental arches but does not evaluate the collapse of maxillary segments.
