ABSTRACT
The selection and arangement of maxillary anterior teeth for edentulous patient have long been recognized as a clinical problem in prosthodontic practice. So this study was directed to evaluate some different guide methods used for the selection of maxillary anterior teeth and to find the correlation between anatomical landmarks with the maxillary anterior teeth in dentulous subject. A specially designed tool was used to represent the Frankfort horizontal plane and the orbital plane on both sides of the face. A lateral right and anterposterior cephalometric radiographs were taken for each subject with the teeth in centric occlusion and the lip in repose. The Frankfort and orbital planes, the long axis of the maxillary canine and the most protruding central incisor were drawn. The Bizygomatic width was measured cilnically and cephalometrically. The results showed that there were significant correlations between the width of the 6 anterior teeth with both Bizygomatic width clinically and interorbital plan distance at Orbitale clinically and cephalometrically
