Summary
This study compared the cutting feel of a Bioram M model tooth to natural teeth. Bioram M demonstrated desirable characteristics, closely mimicking the cutting sensation of a vital natural tooth.
Area of Science:
- Dental materials science
- Biomaterials engineering
- Restorative dentistry
Background:
- Dental education and practice utilize various model teeth for training.
- Evaluating the tactile feedback and cutting characteristics of these models is crucial for effective skill development.
Purpose of the Study:
- To compare the hardness, stickiness, and cutting rate of a crystalline glass ceramics model tooth (Bioram M) against natural extracted teeth and melamine resin models.
- To assess the suitability of Bioram M as a dental training model based on its cutting properties.
Main Methods:
- Extracted human teeth, melamine resin, and Bioram M were used as models.
- Diamond burs attached to an air-turbine handpiece were employed for tooth preparation.
- Subjective tactile sensations (hardness, stickiness) and cutting rate were evaluated.
Main Results:
- Bioram M exhibited desirable characteristics for a dental model tooth.
- The cutting sensation experienced with Bioram M closely resembled that of a natural vital tooth.
- Melamine resin and natural teeth showed differences in tactile feedback and cutting behavior.
Conclusions:
- Bioram M is a suitable model tooth for dental education and practice due to its realistic cutting properties.
- The findings support the use of Bioram M for training dental professionals in tooth preparation techniques.
- Further research could explore other mechanical properties and long-term durability of Bioram M.
