After the loss of natural teeth, the prosthesis for prosthetic services becomes an indispensable part of modern life. They provide effective chewing and aesthetics. To do this more proficient both biologically and functionally place the geometric shaped tooth arch on the specific name. Objective: The aim of this study was to compare the distance between the posterior edge of the incisive papillae and the most prominent part of labial surface of maxillary central incisor surface in various forms of the arch. Study Design: In vitro section experimental study. Place And Working Period: In Punjab Dental Hospital Lahore for one year duration from march 2017 to March 2018. Methodology: 203 university Youngsters and Adults were selected with symmetrical faces and with all the teeth available outside the third molars. subjects with impaired teeth, dental problems, orthodontic or dental restoration lip surfaces were excluded. The selection in the exemplary drawings is standardized for each sample after the upper and lower belts and the Casts obtained are made. Arc shapes were evaluated with morphological explanations. The measurements recorded the distance between a digital vernier caliper modified casts placed on a flat surface with incisive papilla (IP) and a central tooth (CL) for upper cut papillo incisal distance (PID). The Vernier caliper jaw fixed blade was extended 10 mm from the original for effective measurements. Results: 11.06 mm ± 1.46 was the average PID. Among the volunteers 90.6% had oval, squarish in3.9% and tapering arch seen in 5.4%. The mean oval arched PID was 11.04 mm, the 10.84 mm contraction angle and 12.02 mm. Conclusion: The average PID prosthesis proposed for placement of central incisors is 11.06 mm. Oval-shaped forms have a larger presentation. Key Words: papillo-incisal distance, prosthesis, maxillary central incisor. |
