Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0023] refer to Figure 1 to Figure 5 , the miniature test system for measuring the force of the tooth drilling process includes a base 1 , an end cap 2 , a simulated tooth 3 , an end cap bolt 4 , a fixing bolt 5 , a cross ring beam 6 , a ring gasket 7 and a strain gauge 8 .

[0024] The base 1 is made of a square steel plate and placed on a flat table. A stepped circular hole is processed at each of the four corners of the base 1 for fixing the base 1 and other components. A circular through hole is processed in the middle of the base 1. A stepped ring groove is processed along the axial direction, the ring groove is used to install the end cover 2, the ring gasket 7 and the cross ring beam 6, the width of the ring groove is equal to the ring section width of the ring gasket 7, and the end surface of the ring groove is perpendicular to the base Four evenly distr...

Abstract

The invention discloses a miniature testing system for testing the stress of a tooth in the drilling process, and aims at solving the problems that the drilling force for the tooth cannot be measured in the medical test and the training process of dentists. The miniature testing system comprises a base (1), an end cover (2), simulated teeth (3), end cover bolts (4), a fixed bolt (5), a cross ring beam (6), a ring-shaped gasket (7), and strain gauges (8). The miniature testing system has an important significance for the technological development in the field of oral medical measuring equipment.

Description

technical field [0001] The invention relates to a testing device in the field of stomatology, more specifically, it relates to a miniature testing system for measuring the force in the tooth drilling process. Background technique [0002] Dental drill bit is a common equipment in the medical field, mainly used for the treatment of various dental diseases, because the force of the drill bit on the tooth will be transmitted to the nerve during the treatment process, causing great pain to the patient, so in medical experiments or dental Designing a special micro-test system for measuring the force of the tooth drilling process in the training process of doctors is of great significance to the technical development of the field of stomatology measurement. Contents of the invention [0003] The present invention aims at the current situation that it is impossible to measure the stress of the teeth during the drilling process, and provides a device with simple operation, reliabl...
