Correlation of Interalar Width and Maxillary Anterior Teeth for Different Arch Form in Den-Tate Subjects
Statement of problem:
Purpose: The aim was to investigate the relationship between the inter alar width (IAW) and the distance between the maxillary canines tip and also to determine the relation of the ala of nose and canine on individual side, for different arch forms, to aid in artificial denture teeth positioning.
Materials and Method: A total of 300 dentate subjects aged between 18-30 years, of both genders were selected, among them 150 were males and 150 females. The subjects were divided into three group based on their arch forms that is, square arch, ovoid arch and tapered arch forms. The subjects to be photographed were made to achieve the natural head position (NHP). All pho-tographs were analyzed for inter-alar width. The inter-canine width using Adobe Photoshop-7 professional.
Conclusion: It is concluded that maintaining symmetry while fabricating a complete denture is not mandatory. After observing the data it is suggested that in both males and females for all arch forms teeth arrangement can be made with the alar lines extending distal to the premolar.
