“…They found that the anterior and posterior overjets were homogeneous. In recent times, several studies [14][15][16] have evaluated the relationship between the dental and basal arches on the basis of the WALA ridge (named after Will Andrews and Larry Andrews), which connects the most convex points on the mucogingival junction. 13 However, none of these studies analyzed the maxillary arch, and therefore, the horizontal relationship between the upper and lower dentition has not yet been assessed.…”

“…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)

“…In the literature, there are varying results obtained in studies that compared the correlation between the basal arch and dental arch in various malocclusion groups (7,8,24). It has been suggested that the depth of the COS differs between the malocclusion groups (16).…”

“…The union of the FA points determines the dental arch form (5). The relationship between the dental arch and basal arch that is described as WALA to FA, abbreviated as WALA-FA in this study, has been assessed in several malocclusions (6)(7)(8). On the frontal plane, the occlusal table passing the cusp tips of the posterior teeth does not follow the same plane.…”

Objective: To test the hypotheses that (i) there is a significant correlation between the curve of Spee (COS), basal arch (WALA ridge) to dental arch distance (WALA-FA distance) and curve of Wilson (CW) and that (ii) the deepening of the COS is affected by the CW and the WALA-FA distance.Methods: Mandibular models of 50 patients aged between 20 and 35 years were scanned with TRIOS. The xyz coordinate system was determined, and a reference occlusal plane was generated. The depth of the COS, the CW, and WALA-FA distance were measured using an engineering software. Results:The greatest difference in the measurement of the depth of the COS between the right and left was found to be 0.41±0.50 mm in the first molar teeth. On the basis of the results of Pearson correlation analysis, there was no strong correlation between the depth of the COS, the CW, and the WALA-FA distance. Conclusion:It was shown that there was no strong correlation between the depth of COS, CW, and WALA-FA distance. The CW and WALA-FA distance could not be effective in the deepening of the COS.

Aim:To analyze and determine maxillary and mandibular arch form of Gujarati (Indian) adults with normal occlusions. Materials and methods:Fifty seven study models of untreated individuals were examined. Six measurements of both the arches were taken, and five independent ratios were determined. Character and shape of both the arches were studied and compared using various statistical analyses for males and females between both the arches. Results:As moving from anterior to posterior, both the arches diverge proportionally, except in second molar area where slight convergence toward midline was noted. Females had proportionally narrower arch dimensions than those for males. Five arch forms were determined according to relative deviations of various ratio combinations, and all subjects were classified for mandibular arch form by nonhierarchical stepwise method.
