Description
Technical field
Tooth body, tooth are repaired the present invention relates to a kind of survey tool, more particularly to a kind of can accurately be measured in oral restoration
The new-style electronic dentistry multifunctional spiral of the various depth of body preparation and various artificial crown thickness surveys chi.
Background technology
In the department of stomatology, especially in the clinic and teaching of Prosthodontics, the making with various Guan Qiao is repaired in tooth body
During, it repairs the depth of tooth body and tooth preparation depth will follow strict standard in tooth preparation, especially makes
The thickness of various artificial crowns also have strict standard.This just proposes very high requirement to clinician and student, in clinic
In mending course, the operable space of measuring apparatus and the convenience for reading data, and student is in learning process, first has to
The preparation of depth is got hold of in preparation process, the concept of different depth is set up, this is highly important for tooth preparation.
Although there is the method such as tooth preparation depth guide car pin and the dual-purpose slide calliper rule of dentistry to control to prepare depth, depth guiding at present
Car pin can only grind fixed depth, it is impossible to the various depth that measurement is gone out with common in-vehicle pin preparation, and during tooth preparation
Enter the replacing of pin of driving a vehicle, be not easy to the study of student；And the dual-purpose slide calliper rule of dentistry also have measurement accuracy not enough, measured value is not easy to
Read, the problems such as being not easy to clinically use.Though artificial crown thickness measure has Special caliper at present, it possesses measurement hat
A kind of function of thickness, it is impossible to measure the depth of tooth preparation.
Electronic type micrometer caliper is made according to spiral amplification and the principle of swept resistance, i.e., screw rod revolves in nut
Circle, screw rod is just along the distance of rotation axis side's pitch forward or backward, while swept resistance industry moves one
The position of pitch, curent change, data signal is through circuit conversion, over the display corresponding readings change.Therefore, edge axis side
To mobile slight distance, it can just be showed with the reading on circumference.The pitch of the accurate thread of micrometer caliper is Tmm,
Movable mark has 100 evenly divideds, and movable mark rotates a circle, and micrometric screw can advance or retreat Tmm, therefore rotation is each
Small indexing, advances equivalent to micrometric screw or postpones T/100=0.01Tmm.
