Accuracy, Reliability and Clinical Implications of Static Compared to Quantifiable Occlusal Indicators

Area of Science:

• Dentistry
• Biomedical Engineering

Background:

• Occlusal adjustments are critical for dental health.
• Traditional static occlusal indicators rely on subjective interpretation.
• Digital occlusal analysis offers objective measurement capabilities.

Purpose of the Study:

• To review and compare static and digital occlusal indicators for occlusal adjustments.
• To evaluate the evidence supporting each type of indicator.
• To determine the clinical implications for occlusal practice.

Main Methods:

• A comprehensive literature search was conducted in PubMed/MEDLINE.
• Keywords included "Occlusal Indicators," "Occlusal Assessment," "Static," "Dynamic," "Reliability," "Validity," and "Clinical Accuracy."
• 231 papers were identified, with 129 selected for review.

Main Results:

• The Static Occlusal Indicators group had significantly fewer studies (20 papers).
• The Dynamic Occlusal Indicators group comprised more studies (T-Scan: 89; Dental Prescale: 28; Intraoral Scanners: 17).
• Static indicators demonstrated high subjectivity, while dynamic systems showed objective measurement capabilities.

Conclusions:

• Limited evidence supports the use of subjective static occlusal indicators.
• Strong evidence supports digital systems like T-Scan for objective occlusal force and timing analysis.
• Replacing static indicators with digital systems can enhance the accuracy and outcomes of occlusal adjustments.
