Objective: The aim of this study was to investigate the relapse tendency in the maxillary dental arch widths in unilateral cleft lip and palate patients with different types of maxillary arch form. Subjects: Thirty-two unilateral cleft lip and palate patients treated by one-stage surgical palatal closure were included. The subjects were divided into three groups according to the types of the maxillary arch forms: group A, symmetrical arch form; group B, collapse of minor segment; group C, collapse of both segments. Methods: Using dental casts obtained at three different times, relapse in the intercanine, interpremolar, and intermolar widths in each group was assessed and differences between groups were investigated. Results: Patients in group A showed stable results in all measurements. Patients in group B showed posttreatment relapse in the intercanine width only, whereas patients in group C demonstrated significant posttreatment relapses in the interpremolar and intermolar widths. Comparison between groups showed more significant relapse in the interpremolar and intermolar widths of group C than in those of group B. Conclusion: The types of the maxillary arch forms in unilateral cleft lip and palate patients might play a stronger role in the stability of the maxillary dental arch widths after orthodontic treatment in patients with collapse of both segments and a severe degree of maxillary narrowness.

In a mixed longitudinal study, dental arch relationships of 88 consecutive UCLP patients treated at the Nijmegen Cleft Palate Centre were evaluated using the Goslon Yardstick. On the basis of timing of hard palate closure, the patients were divided into four groups. Mean age of hard palate closure in group A (n = 18) was 1.5 years, in group B (n = 26) 4.6 years and in group C (n = 18) 9.4 years. In group D (n = 26, no patient older than 10 years) the hard palate was still open. Four stages of dental development were distinguished; deciduous dentition, early mixed dentition, late mixed dentition and permanent dentition. Reproducibility of scoring with the Goslon Yardstick was good for all stages of dental development. No differences in dental arch relationships were found between the four groups. In 86% of the cases, the dental arch relationships of UCLP patients treated in Nijmegen were acceptable. Pharyngeal flap surgery had minor unfavorable effects on dental arch relationships.

Objective To study the effect of infant orthopedics (IO) on maxillary arch form and position of the alveolar segments. Design Prospective two-arm randomized, controlled trial in parallel with three participating academic cleft palate centers. Treatment was assigned by means of a computerized balanced allocation method. Setting Cleft palate centers of Amsterdam, Nijmegen, and Rotterdam, the Netherlands. Patients, Participants Infants with complete unilateral cleft lip and palate and no other malformations. Interventions One group (IO+) wore passive maxillary plates during the first year of life; the other group (IO−) did not. All other interventions were the same. Main Outcome Measure(s) The presence of contact and/or overlap (collapse) between the maxillary segments at maxillary casts made shortly after birth, at 15, 24, 48, 58, and 78 weeks. Survival experience of contact and collapse with time as well as the frequencies of different arch forms and severity of collapse were evaluated. Results Comparable arch forms with no contact or overlap of the maxillary segments were seen at birth in both groups. With time the frequency of collapse increased, with no significant differences between groups. No significant group differences were found with respect to the survival experience of contact and collapse or for the severity of collapse at the end of the observational period. Conclusions Infant orthopedics does not prevent collapse and can be abandoned as a tool to improve maxillary arch form.

Form Change

Objective: Quantitative descriptions of form (size and shape) changes are significant to the understanding of the development, treatment planning, and prognosis of patients born with cleft lip and palate. This study compared the results of traditional dental arch form change measurements, such as width, depth, perimeter, and area, with four numeric methods: finite element scaling analysis, macroelement method, Euclidean distance matrix analysis, and conventional least-squares and resistant-fit theta rho Procrustes analyses. Design: Using tooth cusp landmarks on maxillary study casts, form change measurements of a male with complete bilateral cleft lip and palate at ages 2, 5, and 6 years were made comparing each age to the next older. Results and Conclusions: With the exception of the 2- to 5-year resistant-fit analysis, all numeric methods: 1) provide comparable results, 2) provide more detailed descriptions than do traditional methods, and 3) provide results that correlate well with the reported effects of increased lip pressure due to lip closure surgery. The use of finite-element scaling analysis on study casts is somewhat limited since: 1) there is more than one solution at teeth shared by many finite elements, 2) gross averaging of form change occurs within triangular elements, and 3) solutions can vary with the choice of element location. The use of the macroelement method circumvented the above finite element limitations with out compromising finite-element advantages. Procrustes results vary with the chosen superposition algorithm. The choice of the most appropriate Procrustes method required some a priori knowledge of form difference. The large number of results obtained by Euclidean distance matrix analysis and the nongraphic presentation of these results hamper quick interpretation but may be best suited for definitive statistical analysis. The graphic representation of both the magnitude and direction of: 1) landmark displacement in the Procrustes analyses (once size difference is eliminated), and 2) the rate of form change in the macroelement method provide an intuitive appreciation of how and where the casts differ.

Maxillary Arch

The development of the dental arch is well designed for adaptive and compensatory growth. In this study, the relationship between the sleep position and dental arch development was Investigated. A group of 42 infants with unilateral complete cleft lip and palate with either prone (16) or supine (26) sleep position were seen in the craniofacial center. All infants were less than 1 month of age at the initial visit. Dental impressions of the maxillary arch were taken at the initial visit and just before cheiloplasty. Ten arch dimensions were measured in each dental cast and the longitudinal change in each dimension was compared between the prone sleep group and the supine sleep group. Statistically significant changes were detected in the growth rate of the following dimensions: intercanine width, intertuberosity width, alveolar cleft width, anterior cleft width, and posterior cleft width. This study indicated that sleep position affected maxillary arch development. Infants sleeping in the prone sleep position tended to have narrower arch width and cleft width.

Dental Arch Form

This study evaluated the early changes of maxillary alveolar arches of operated unilateral cleft lip and palate patients. Dental casts were available at four age increments. Triangular flap cheiloplasty was carried out at an early age. Two-stage palatoplasty by vomer flap and soft palate closure took place later. Prior to lip repair, the alveolar arches were classified according to the relationship between greater and lesser segments. Almost a quarter had overlap of the alveolar segments with no contact between the alveolar ridges at the cleft site; some had no overlap with contact of the alveolar segments in the cleft region; almost a quarter had both overlap of the alveolar segments and contact; and almost half had no overlap of the segments and the alveolar ridges were not in contact at the cleft site. After lip repair, the arch relationships were examined and the percentage of patients in each of the four groups indicated a moulding effect of lip repair on the alveolar segments. This moulding effect caused the alveolar segments in most patients to be in contact at the cleft site. Most of these also had segment overlap. All patients were re-examined shortly after palatal repair. The trend for segment overlap and contact continued after palate surgery. However, when all patients were seen at age 4, percentages of patients in each group indicated that previous overlap of segments improved to a more desirable nonoverlapped relationship in approximately half of the patients. The other half continued to demonstrate arch collapse, in excess of what would be considered ideal ridge relationship.

Bilateral Cleft Lip

The aim of this study was to describe maxillary and mandibular dental-arch form and occlusion in bilateral cleft of the lip and palate (BCLP) from 3 to 17 years of age and to compare their characteristics with a normative sample. A sample of 22 patients with BCLP was investigated, with a noncleft control sample used for comparison. Dental-arch dimensions were studied on dental casts. A comparison between both groups was made at fixed time intervals. From 9 years of age, the cleft sample showed a significantly smaller maxillary depth. Maxillary dental-arch widths were also significantly smaller than in the control group over the whole age period. Mandibular dental-arch measurements were very similar In both groups, although smaller first-molar widths were noted in the BCLP group beginning at 12 years of age. A tendency for end-to-end occlusion was found, which became more clear with age and was most markedly in the canine region.
