Assessment of Anatomical Landmarks in Dentulous Patients to Calculate Height of Occlusal Registration Blocks

Abstract

Objective: To determine the mean rim height in dentulous patients by assessing anatomical landmarks.

Study Design: Descriptive cross sectional study

Place and Duration of Study: This study was conducted at the Prosthodontics Department of Liaquat University of Medical & Health Sciences, Jamshoro, Sindh from Sep 2022 to March 2023.

Methods: Thirty patients were included in this study. Impressions were taken with alginate and models were poured. Measurement were taken using digital Vernier caliper for both arches on first permanent molars and canines from cusp tip to sulcus depth. Three readings were taken to identify a mean in case of any human or machine error.

Results:  The patients' average age was 28.10±5.97 years. Mean height of 16.18 mm, 15.63 mm, 15.46 and 15.35 mm for First Molars teeth no. 16, 26, 36 and 46. Mean height was 19.5 mm, 19.07 mm, 18.09 mm and 18.06 mm for Canines teeth no. 13, 23, 33, and 43. The mean of mean height of all Molars teeth and all Canines teeth were 15.65±1.16 mm and 18.68±1.47 mm respectively.

Conclusion: In this population, for complete removable dental prosthesis fabrication, It is feasible to keep the maxillary anterior record rim's preset height of 19–20mm in male patients and 18-19mm in female patients. It could be help in fabricating denture which is functionally and aesthetically pleasing for edentulous patients.
