Summary
Determining the correct occlusal plane is crucial for dental restorations. The Broadrick curve, when used with a semi-adjustable articulator, aids in accurately establishing this plane, especially in patients with missing posterior teeth.
Area of Science:
- Dentistry
- Restorative Dentistry
- Dental Anatomy
Background:
- Proper occlusal plane determination is vital for the success of multiple long span posterior dental restorations.
- Deviations in the occlusal plane can negatively impact both short-term and long-term restorative outcomes.
Purpose of the Study:
- To identify the appropriate occlusal curve for individual patients undergoing dental restoration.
- To compare the deviation of the clinically determined occlusal curve against ideal curves.
Main Methods:
- Twenty subjects' dental models (maxillary and mandibular) were analyzed.
- Inter-occlusal records were used to articulate casts in a semi-adjustable articulator.
- Measurements were taken from cusp tips to the Broadrick curve along the tooth's long axis.
Main Results:
- A statistically significant difference (P < 0.05) was observed in the deviation from the Broadrick curve.
- This deviation was notably higher in patients who had lost posterior teeth compared to those with full dentition.
Conclusions:
- Accurate determination of the occlusal plane is essential for successful long span posterior restorations.
- Utilizing the Broadrick flag on a semi-adjustable articulator facilitates correct occlusal plane determination.
