Significance of intercom missural width and anterior teeth selection

The objective of the present study was to determine the correlation between the intercommissural width and the combined mesiodistal width of maxillary six-anterior teeth in the study. It was a cross sectional study and was carried out from Aug 2011 to Jan 2012. Non-probability purposive sampling. The present study included 159 dentate subjects having Angle's class I molar and canine relationships. The patients were selected from the department of Prosthodontics, Lahore Medical and Dental College, Lahore. The subjects with history oforthodontic treatment, extractions, drifting and attrition of the teeth were excluded. All those subjects having any restoration in upper anterior segment, any facial deformity, crowding or spacing of anterior teeth were also not included. The informed consent was obtained. The patients were seated in the upright position and were asked to look straight. Before the measurement of intercommissural width subjects were asked to widely open and close the mouth several times. It was done to fatigue the muscles and to relax them during the measurement. The distance between the left and right commisures of mouth were measured using digital caliper. The casts of maxillary arches were used to measure the intercanine width. The distal margin of both the maxillary canines were marked on each sides of the maxillary cast. A dental floss was placed at the greatest curvature of the maxillary arch and was marked at the distal margin of the canines. The dental floss was sectioned at the markings and the distance was measured between the marks using digital caliper. Both the parameters were measured three times by the single person to ensure the accuracy and the mean was taken. The measurements were recorded in a Proforma. The statistical results of this study showed that there was no correlation between the intercommissural width and the combined mesiodistal width of maxillary anterior teeth. It was concluded that the intercommissural width was not a good predictor for the selection of maxillary anterior teeth width for edentulous patients in the study group

role of the interalar width in the anterior teeth selection

The objective of the present study was to determine the correlation between the interalar width and the combined mesiodistal width of maxillary six-anterior teeth in Pakistani population. It was a cross sectional study and was carried out from May 2011 to November 2011. A total of 159 dentate subjects fulfilling the inclusion criteria were selected from the department ofProsthodontics, Lahore Medical and Dental College, Lahore. The demographic information like age *' and sex were recorded and the informed consent was taken. The patients were seated at upright position and asked to look straight. The interalar width was determined by measuring the external width of the alae of the nose at the widest point by using a digital caliper. With subject in a relaxed position, the recording part of the caliper was brought in contact with the outer surface of both alae without applying pressure. The inter canine width was measured from the maxillary stone cast with the help of dental floss, placed at the greatest curvature of the maxillary arch. The distal surfaces of both the maxillary canines were marked on the maxillary cast. The dental floss was sectioned and made straight. The digital caliper was used to measure the distance between the marks. Both the parameters were recorded three times by the single person to ensure the accuracy and the mean was taken. The measurements were recorded in a Proforma. The statistical results of this study have shown that there is no correlation between the interalar width and the combined mesiodistal width of maxillary anterior teeth. lt was concluded that the interalar width is not a reliable predictor for the selection of the width of maxillary anterior teeth in the edentulous patients in Pakistani population

role of interpupillary distance in the selection of anterior teeth

The objective of the present study was to determine the correlation between the interpupillary distance and combined mesiodistal width of maxillary six-anterior teeth in the study.It was a cross sectional studyand was carried out from May 2011 to November 2011. Sampling: Non-probability purposive sampling. A total of 159 dentate subjects with Angle's class I molar and canine relationships were selected from the department of Prosthodontics, Lahore Medical and Dental College, Lahore. The exclusion criteria included the subjects with history of orthodontic treatment, extractions, drifting and attrition of the teeth. Subjects having any restoration in upper anterior segment, any facial deformity, crowding or spacing of anterior teeth were also excluded. The informed consent was taken. The patients were seated in the upright position and were asked to look straight. The interpupillary distance was measured using the digital caliper. The measurement was made from the mid pupil of one eye to mid pupil of the other eye. The intercanine width was measured from the casts of maxillary arches with the help of dental floss placed at the greatest curvature of the maxillary arch. The distal surfaces of both the maxillary canines were marked on each sides of the maxillary cast. The dental floss was sectioned at the markings and made straight .The distance was measured between the marks using digital caliper. Both the parameters were measured three times by the single person to ensure the accuracy and the mean was taken. The measurements were recorded in a predesigned Proforma. The statistical results of this study showed that there was no correlation between the interpupillary distance and the combined mesiodistal width of maxillary anterior teeth. It was concluded that the interpupillary distance was not a reliable predictor to select maxillary anterior teeth width for edentulous patients in the study group
