The two-in-one, self-threading, self-shearing pin: efficacy of insertion techniques
Journal of the American Dental Association (1939)
|July 1, 1978
Summary
The TMS minim two-in-one, self-shearing pin fully inserted into a 2-mm channel using a hand wrench. However, it failed to reach full depth when inserted with an Auto Klutch handpiece.
Area of Science:
- Dental instrumentation
- Biomaterials engineering
Background:
- The TMS minim two-in-one, self-shearing pin is designed for dental procedures.
- Ensuring proper pin insertion depth is critical for successful outcomes.
Purpose of the Study:
- To evaluate the insertion depth and shearing behavior of the TMS minim two-in-one, self-shearing pin.
- To compare the performance of the pin when inserted using different methods.
Main Methods:
- An in vitro study was conducted.
- The TMS minim two-in-one, self-shearing pin was inserted into a 2-mm pin channel.
- Insertion was performed using a hand-turned wrench and an Auto Klutch handpiece.
Main Results:
- The pin reached maximum depth and sheared off as intended when inserted with a hand-turned wrench.
- The pin did not achieve the full 2 mm channel depth when inserted with the Auto Klutch handpiece.
Conclusions:
- The insertion method significantly impacts the performance of the TMS minim two-in-one, self-shearing pin.
- Hand-turned wrench insertion appears more effective for achieving full depth with this specific pin design.
