3D-Printed Artificial Teeth: Accuracy and Application in Root Canal Therapy
Journal of Biomedical Nanotechnology
|June 16, 2018
Summary
This study demonstrates that 3D-printed artificial teeth accurately replicate extracted teeth, improving root canal filling precision. This novel approach enhances the success rate of root canal treatments using cone-beam computed tomography and multi-jet printing.
Area of Science:
- Biomaterials Science
- Dental Technology
- Medical Imaging
Background:
- Accurate root canal preparation is crucial for successful endodontic treatment.
- Existing methods for replicating tooth anatomy for treatment planning have limitations.
Purpose of the Study:
- To evaluate the compatibility and accuracy of 3D-printed artificial teeth created using cone-beam computed tomography (CBCT) and multi-jet printing technology.
- To assess the efficacy of these 3D-printed models in guiding root canal filling procedures.
Main Methods:
- Extracted premolars were scanned using CBCT, and data were used to create 3D models.
- Artificial teeth were 3D-printed using multi-jet printing technology.
- 3D deviation analysis and cross-section measurements were performed to compare printed and original teeth.
- Clinical application involved using 3D-printed models to select master gutta-percha for root canal filling, with outcomes assessed by X-ray.
Main Results:
- 3D-printed artificial teeth showed high accuracy and compatibility with original extracted teeth.
- No significant differences were found in root canal cross-sections at various depths.
- Clinical cases demonstrated good quality root canal fillings using the 3D-printed model-guided approach.
Conclusions:
- The combination of CBCT and multi-jet printing technology yields accurate 3D-printed artificial teeth.
- These models provide a reliable guide for selecting appropriate master gutta-percha for root canal filling.
- This technology offers a promising new method to enhance the precision and success rate of root canal treatments.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

102.9K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Accuracy, limits, and approximations are common in many fields, especially in engineering calculations. These concepts are imperative for ensuring that a given value is as close as possible to its true value.
Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
The accuracy of any solution is based on the...
