Abstract

Statement of Problem: The determination of the DENTAL MIDLINE is necessary in most dental procedures. One of the methods to fulfill this goal is to determine the FACIAL MIDLINE based on the midpoints of the forehead, nose, upper lip and chin. However, for various reasons, this method has not always been proved successful. In such cases, different techniques, based on the investigations in the edentulous patients, have been suggested.Purpose: The aim of this study was to investigate the conformity of some landmarks such as LABIAL FRENUM, INCISIVE PAPILLA and MID PALATAL SUTURE with dental and FACIAL MIDLINEs among people with natural dentition in order to obtain accurate anatomic landmarks for denture replacement.Materials and Methods: In this descriptive study, 96 dental students, having all their permanent teeth and without any orthognathic problem, were chosen. For each subject, Alginate impressions and dental casts were prepared. Then, centric occlusion was recorded with a biting wax and the facial mid line was determined on the anterior part of it. The distances from the FACIAL MIDLINE to the upper teeth midline, INCISIVE PAPILLA, LABIAL FRENUM and MID PALATAL SUTURE were determined with a special tool and were measured by a VERNIEH two times. In order to analyze the results, Chi- Square and t-student tests were used.Results: The average of FACIAL MIDLINE distance to the upper teeth midline, the LABIAL FRENUM, the INCISIVE PAPILLA and the MID PALATAL SUTURE were 0.83±0.60, 0.67±0.54, 0.83±0.63 and 0.81±0.62 mm, respectively. There was no significant difference between males and females. LABIAL FRENUM showed the minimum distance to the FACIAL MIDLINE, while the INCISIVE PAPILLA had the maximum. There was no significant difference between these anatomic landmarks, in conformity or unconformity with the FACIAL MIDLINE Conclusion: Considering the low percentage of the subjects with complete conformity and the lack of significant differences between these three landmarks, it is suggested that there is no superiority among these landmarks for the determination of FACIAL MIDLINE. The similar distances from the FACIAL MIDLINE to the INCISIVE PAPILLA and upper teeth midline indicate that using INCISIVE PAPILLA to determine the upper teeth midline in edentulous patients lead to normal face.
