ABSTRACT
Objective: To evaluate the mean vertical distance between the mesial incisal edge of maxillary central incisor and incisive papilla in various arch forms.
Study Design: Descriptive/ Cross sectional study
Place and Duration of Study: This study was conducted at the Department of Prosthodontics, de’ Montmorency- College of Dentistry/Punjab Dental Hospital, Lahore for 6 months from February 2018 to August 2018.
Materials and Methods: The study consisted of 100 patients attending the Prosthetic outdoor department of Punjab Dental Hospital, Lahore meeting the inclusion criteria. The vertical distance between mesial incisal edges of central incisors and the center of the incisive papilla was evaluated using vernier caliper, after mounting the casts on surveyor. Center of the incisive papilla was transferred on the labial surface of central incisor with the help of carbon marker. Arch forms were assessed by using Diagnostic Orthoform Template as recommended by 3M Unitek. Data was analyzed on SPSS version 21.0. Chi-square test was applied for statistical significance.
Results: The vertical distance between mesial incisal edge of maxillary central incisors and incisive papilla ranged from 6.89 mm to 7.03 mm with the mean vertical distance of 7.00±0.026 mm. The mean papillo incisal distance(PID) was 6.99±0.027 mm in ovoid, 6.98±0.020 mm in square and7.01±0.018 mm in taper arch form.
Conclusion: The results can be used by the dentist and laboratory technician as a foundation for construction of maxillary occlusal rims that are used for the establishing the occlusal plane in different arch forms, in conjunction with the support of other anatomical landmarks.
