“…Previous reports have stressed the importance of the coordination between the upper and lower arches and claimed that the absence of this coordination may lead to functional and esthetic problems. [9][10][11][12] Few studies have been performed on the shape of the basal arch, [13][14][15][16] whereas several studies have examined the characteristics of the dental arch form in different ethnic groups. [17][18][19][20][21][22][23] Some previous studies were aimed at finding mathematical relations to describe the dental arch.…”

Objective:The purposes of this study were to evaluate the relationship between the dental and basal arch forms; to analyze their differences in the tapered, ovoid, and square arch forms in normal occlusion by using three-dimensional (3D) virtual models; and to test the hypothesis that the overjet and maxillomandibular basal arch width difference have a significantly positive correlation. Methods: Seventy-seven normal occlusion plaster casts were examined by 3D scanning. Facial axis (FA) and WALA points were digitized using the Rapidform 2006 software. The dimensions of the dental and basal arches and the overjet were measured. The samples were classified into 3 groups according to arch forms: tapered (n = 20), ovoid (n = 20), and square (n = 37). Analysis of variance (ANOVA) was used to compare the dental and basal arch dimensions. The Pearson correlation coefficients between the intercanine as well as the intermolar widths at the FA and WALA points were calculated. Results: With regard to the basal arch dimensions, the tapered arch form showed a larger mandibular intermolar depth than the ovoid. Strong correlations were noted between the basal and dental intermolar widths in both the upper and lower arches (r = 0.83 and 0.85, respectively). Moderate correlation was found between the upper and lower intercanine widths (r = 0.65 and 0.48, respectively). Conclusions: The 3 dental arch form groups differed only in some dimensions of the skeletal arch. Moderate correlations were found between the basal and dental intercanine widths. These findings suggest that the basal arch may not be a principle factor in determining the dental arch form. (Korean J Orthod 2011;41(4):288-296)

“…Typically, changing the shape of alveolar ridge is seen as usual as bone remodeling process during the teeth movement (5, 6), even in this case, a symmetrical dental arch and an ideal teeth-bone relationship can be gained through the end of such routine orthodontic treatment. However, if only teeth are moved through the collapsed alveolar bone with uncontrolled orthodontic mechanics, teeth fenestration from cortical bone might be apprehended to be occurred (1,2). Therefore, controlled orthodontic mechanics with light force is required for this complicated situation, and it usually takes a longer treatment period.…”

“…However, it could induce root blunting, resorption, or fenestration during the treatment, if the affected teeth-bone relationships were poor (1,2). Moreover, the treatment duration may be prolonged in a traditional orthodontic treatment because of those mechanical and physical complications.…”

This case report describes a new surgical orthodontic approach involving alveolar bone distraction osteogenesis for correction of asymmetric maxillary dental arch. The treatment was also combined with conventional orthognathic surgery to improve mandibular lateral deviation. This new treatment strategy provided an ideal dental arch and a symmetric facial appearance efficiently and effectively. INTRODUCTIONAn asymmetric dental arch associated with skeletal problem often results in an

“…1,2 Coordination between the upper and lower arches is one of the most important aspects of achieving stable functional and esthetic results during orthodontic treatment. Because a transverse discrepancy could induce an adverse periodontal response, unstable dental camouflage, and functional and esthetic problems, [3][4][5][6] maintenance of an adequate overjet during treatment is essential.…”

Objectives:To compare the amounts of anatomical overjet measured from facial axis (FA) points with the amounts of bracket overjet measured from bracket slot center (BSC) points. Materials and Methods: The samples consisted of 27 subjects with normal occlusion whose models were fabricated with a three-dimensional (3D) scanner and the 3Txer program (Orapix Co Ltd, Seoul, Korea). 3D virtual brackets (0.022Љ Slot, MBT setup, 3M Unitek, Monrovia, Calif) constructed with a 3D-CAD program were placed on an FA point with the 3Txer program. The arch dimension and the amounts of overjet from FA and BSC points were measured. Paired t-tests and analysis of variance (ANOVA) tests were used for statistical analysis. Results: No significant difference in arch width and depth was observed between FA and BSC points. Although the amounts of overjet measured from FA points showed homogenous distribution, a tendency to decrease from the anterior segment (2.3 mm) to the posterior one (2.0 mm) was noted. However, the amounts of overjet measured from BSC points were variable, especially in the premolar and molar areas. Significant discrepancies in the amounts of overjet in most of the areas between FA and BSC points (more than P Ͻ .05), except the lower second premolar and second molar areas, were reported, even though insets and offsets are part of the prescription for the base of straight-wire appliance (SWA) brackets. Conclusions:The hypotheses that the amount of overjet measured from BSC points was 3 mm through the whole segments and that distribution of the amounts of overjet from BSC points was the same as that from FA points were rejected.
