The Selection of Maxillary Anterior Teeth Width in Kashmiri Population

Introduction: Determining the width of maxillary anterior teeth is a difficult aspect in complete denture fabrication. The width of maxillary anterior teeth is determined by taking various anatomical landmarks on the face as a guide, such as the interpupillary, interalar, intercommissure and interzygomatic distance, etc. The present clinical study was carried out to evaluate the relationships between maxillary anterior teeth measurements (canine to canine and central incisor width) and various horizontal facial parameters. Materials and methods: The facial and dental measurements were obtained directly from 60 Kashmiri  undergraduate dental students by using vernier calliper and dental floss. Result: Correlation analysis was done using Pearson’s correlation analysis and it was determined that the incisor width and canine to canine distance show positive correlation with some of the facial measurements. Conclusion: This study inferred that while most of the measurements showed a positive correlation with the incisor width and canine width in the different face forms none of them were found to be significant.&nbsp

Correlation between Vertical Dimension of Occlusion and Finger Length in Kashmiri Population

Introduction: Measurement of accurate vertical dimension of occlusion (VDO) is of prime importance to the dentist especially a prosthodontist. Though many methods have been proposed in recording VDO in the past but none of them fulfills the criteria of accuracy, reproducibility and ease. This study employs theuse of length of fingers to measure VDO in Kashmiri population. Materials and methods: The study was conducted on 60 dentulous subjects which include 30 males and 30 females in the age range of 18 to 25 years. Measurement of VDO and length of fingers was recorded using a digital vernier caliper. Correlation between VDO and length of fingers was studied using Spearman’s coefficient. Result: Vertical dimension of occlusion was found to be almost the length of index finger in males and little finger in females in Kashmiri population. Conclusion: The study revealed that length of index finger is almost equal to VDO in males and length of little finger is almost equal to VDO in females.&nbsp

Comparison of biomechanical differences by FEM between labial and lingual orthodontic mechanotherapy involved in canine retraction

Introduction- FEM is a mathematical method in which the shape of complex geometric objects and their physical properties are computer-constructed. Physical interactions of the various components of the model can then be calculated in terms of stress and strain, detailed information which is difficult to obtain by any other experimental or analytical means due to the interaction of anatomical structures with the surrounding tissue. Aim- Comparison of biomechanical differences by FEM between labial and lingual orthodontic mechanotherapy involved in canine retraction. Material & Method - ANSYS software was preferred over others for the analysis. As ANSYS can import computer assisted designing (CAD) data and also enables to build geometry, in the current study, we have shown the simulated individual (sequential) canine retraction using the sliding (friction method) mechanics by an elastic component. Sliding mechanics was preferred over the closing loop mechanics (frictionless method) Results- Stress in the PDL and Alveolar bone were calculated and depicted. Conclusion- On retraction, the high stress was produced with the Labial system in the PDL and alveolar bone that gradually reduced on force degradation. On combined force application slight increase in stress was noticed
