Microcontroller Based Instrumentation System for Measurement of Strength of Cementing Medium Used in Dental Restorations: Orthodontic Studies

摘要

This paper is concerned with the design of a Micro-controller based Instrumentation system for strength measurement of cementing medium used in dental restorations. A comprehensive analysis of various types of cementing media used to cement various dental restorations such as crowns, bridges etc. are presented. Effects of various cementing media on the retention of dental post in the root canal have been estimated. The system is mainly consists of strain gauges mounted on a cantilever, a specially design amplifier, data acquisition system (ADC0809), Micro-controller (8051) and a display unit. The hardware and software have been integrated into a composite system. The main features of the system are its simplicity, reliability, consistency, cost effectiveness and ease of use.
