ABSTRACT:
Aim: The aim of the study is to compare the appearance of the finish line by an observational method with a new method of taking an impression and dislocation of gingival tissue without the gingival cord. Place and Duration: In the prosthodontics Department of University Medical and Dental Hospital, Faisalabad for six months duration from September 2019 to February 2020. Methods: Twenty-one (21) patients were selected in this study who did not suffer from any supporting tissue disease (such as bleeding or gingivitis). Patients needed crowns for molars. Three impressions were taken from each patient, and the total number of impressions was 63. After the preparation, the first impression was made using the traditional method (putty - rinsing) without gingival retraction. The second impression was made by the observational method. All final impressions were filled with Acryl, completely or only for the prepared tooth area. Then the rules were filled with plaster. The Cochran and Mc A comparison between two methods for gingival retraction (traditional and observational) on the marginal accuracy of the final models. Nemar tests were used to investigate the differences between the means of both groups. Results and conclusions: The results showed that there are statistical differences between the first and second groups. The traditional method was found to be superior to the other. While the observation method is good, the traditional method is much better. Key Words: gingival retraction, marginal accuracy, impression.
