Relationship of the inter-condylar width with mandibular inter-canine width

Aesthetic tooth selection and physiological tooth arrangement are the objectives of the complete denture fabrications. The objective of this study was to determine the relationship of the intercondylar width with mandibular inter-canine width. This cross-sectional comparative study was conducted in Department of Prosthodontics, Lahore Medical and Dental College, Lahore from January to June 2011. A total of 250 dentate subjects were selected according to the inclusion criteria. Maxillary and mandibular arch impressions were taken. The distance between the cusp tips of mandibular canines was measured by using vernier calliper. The inter condylar width was measured using arbitrary face bow. The width between the two condylar rods was measured with vernier calliper in millimetres. Every width was measured three times by the same operator to ensure the accuracy. Data recorded on the Performa for statistical analysis. Pearson correlation coefficients [r] for the inter condylar width and mandibular inter-canine are showing positive correlation and significant [r=0.24, p=0.0005]. Inter-condylar width provides significant measurements for the selection of anterior teeth in edentulous patients

Freeway space measurement by Willis gauge and sprung divider

To compare the accuracy of Willis gauge and Sprung divider in determination of freeway space in dentate subjects. Cross-sectional comparative study. This study was carried out at Department of Prosthodontics, Lahore Medical and Dental College, Lahore from March 2010 to August 2010. Three hundred dentate subjects were included in this study. Both Willis gauge and Sprung divider methods were performed on same subject to measure the freeway space. Subjects were seated in comfortable upright position with unsupported head. Freeway space was measured by both Willis gauge and Sprung divider. The difference between the two measurements of rest position and maximum intercuspation was taken as freeway space. The collected data was entered in proforma. SPSS version 17 was used to analyze the data. Mean and SD was taken for age and gender. The measurement of both methods were compared through chi square test p value < 0.05 was considered significant. Out of 300 subjects, freeway space was achieved 217 [72.33%] with Willis Gauge and in 247 [82.33%] subjects freeway space was achieved with Sprung Divider. Although the achievement rate was slightly high with Sprig Divider as compare to Willis gauge method but it was non-significant [p-value = 0.078]. Sprung Divider measurement of freeway space is somewhat superior to Willis gauge

Correlation between intercondylar distance and mandibular intermolar distance for teeth arrangement

The objective of this study was to find out the potential relationship of intercondylar distance with mandibular intermolar distance. It was a cross-sectional comparative study and was carried out from August 2011 to Jan 2012. The present study was carried out on 250 dentate subjects selected from the department of Prosthodontics, Lahore Medical and Dental College, Lahore. The orthodontically treated subjects and those with congenital or acquired orofacial deformities were also excluded. Al the subjects with a history of tempro-mandibulr joint dysfunction and pain were not included in the study. The impression of the maxillary arch was obtained using irreversible hydrocollide. The vernier caliper was used to measure the distance between the mesiobuccal cusp tips of mandibular first molars. The distance between both the condyles was recorded using an arbitary face bow. The intercondylar distance was measured in millimeters with the help of the vernier caliper. For accuracy every distance was measured three times by the same operator and the mean taken. For the statistical analysis the data was recorded on the proforma. The statistical results of the present study showed that the Pearson correlation coefficients [r] for the intercondylar distance and mandibular intermolar are showing positive correlation and significant [r=0.54 p=0.0005]. It was concluded that the Intercondylar distance measurement can be utilized for the arrangement of posterior teeth in edentulous patients
