Comparison between dental arch dimensions and form in complete dentures and natural dentition Arch Dimension Measurement; Complete denture; Natural Dentition; Arch Form.
Objectives: To investigate dental arch dimensions and arch form of complete denture prosthesis made by students at University of Malaya and compare it with dental arch dimensions and form of normal natural dentation of same Malaysian community.
Methods: A total of 43 Complete dentures (24 maxillary, and 19 mandibular). All samples belongs to 26 Malaysian edentulous The dentures were collected from university of Malaya undergraduate students’ patient. Inter-canine width(IC) and inter-molar width (IM) with digital caliper (CD-6” CSX, A Mitutoyo, Japan) and arch form is estimated with arch shape templates (Orthoform; 3M Unitek, Monrovia, CA, USA). Same measurements have done for 40 intact normal class I occlusion fully dentate casts (20 maxillary, and 20 mandibular).
Results: complete dentures and natural dentation showed no significant difference in arch dimension(IC & IM) with p-value >0.05. Most of the maxillary arch form were ovoid, where the mandibular arch were tapered. Further, Complete dentures dimensions showed not significant differences between in gender
Conclusions: students of undergraduate program in Faculty of Dentistry, University of Malaya have managed to determine and arrange the posterior artificial teeth to simulate close position of the natural dentition of patients using the anatomical biometric guides on the working cast suggested in previous studies and all the further adjustment chairside to determine the neutral zone.
