Abstract
Background: Computers have been applied for information processing in medicine and dentistry. This study was to design a special computer program that helps the dentist to select, and design a proper maxillary major connector made of different types of materials with minimum dimensions and adequate mechanical properties. Materials and methods: A special computer program was performed to select suitable dimensions of maxillary major connectors. The computer program was performed according to two principles related to transverse strength and distortion of 48 specimens of maxillary major connector of two different dimensions (Width and thickness) and materials (cobalt–chromium molybdenum in addition to other type) were prepared and tested in part I. Results: The formulated program (Run) showed a correlation results with the manual tests through linear curves analysis of load-deflection of transverse strength, and the proportional limits of each design of major connectors in relation to their width, length, and thickness. Conclusion: This program is applicable to all types and materials of major connectors, and the major connector should be with the minimum dimensions possible but compatible with the rigidity.
