EVALUATION OF MANDIBULAR RESIDUAL SURFACE AREA IN INDIAN POPULATION: A PILOT STUDY

Abstract

Introduction: Mandibular residual ridge surface area is an important parameter which accounts for the denture support in the patient’s mouth. This pilot study was done to determine the average residual ridge surface area of Indian population; both males and females.
Materials and Method: The mandibular denture was obtained from the subject and silicon rubber based impression material was adapted on to the intaglio surface of the denture. The denture base area corresponds to the residual ridge surface area of the individual. Once the material has set completely; it was retrieved. A graph paper was adapted over the positive replica of the residual ridge to determine the surface area in mm2.
Result: The mean surface area of mandible for male is 27.38mm2 and that of female is 23.46mm2.
Conclusion: Mandibular residual ridge surface area of males is greater than that of females among Indian population.
