|September 1, 1981
Summary
Choosing the right interocclusal record material is crucial for accurate dental casts. Elastomers demonstrated the least errors, outperforming Aluwax and Superbite, with operator experience showing no significant impact.
Area of Science:
- Dental materials science
- Prosthodontics
- Clinical dentistry
Background:
- Accurate dental casts are essential for successful prosthodontic treatment.
- Interocclusal record materials are used to capture the relationship between dental arches.
- Variability in material performance and operator technique can affect cast accuracy.
Purpose of the Study:
- To evaluate the reliability and accuracy of seven different interocclusal record materials.
- To assess the influence of operator experience on the accuracy of dental casts.
- To compare the performance of elastomers versus other record materials.
Main Methods:
- Seven interocclusal record materials were tested.
- Three operators with varying experience levels manipulated the materials.
- Casts were assembled using the recorded interocclusal relationships.
- Mounting discrepancies and errors were statistically analyzed.
Main Results:
- Aluwax exhibited the highest variability and lowest reliability.
- Superbite consistently produced open cast relationships.
- Five tested elastomers yielded the fewest errors.
- Different thicknesses of elastomeric records led to statistically significant mounting discrepancies.
- Operator experience did not significantly influence performance accuracy.
Conclusions:
- Elastomeric interocclusal record materials are recommended for their superior accuracy and reliability.
- Material selection and potentially thickness are critical factors in achieving precise dental casts.
- Operator experience has a minimal impact on the accuracy of dental cast assembly with these materials.
