[Periotest method for the quantitative assessment of occlusal loads]
Deutsche Zahnarztliche Zeitschrift
|July 1, 1990
Summary
The Periotest device offers a new, objective way to measure occlusal load and assess the "dimension of occlusion". This helps evaluate the functional impact on the periodontium, especially with occlusal restorations.
Area of Science:
- Dental occlusion
- Periodontal biomechanics
- Diagnostic technology
Context:
- Assessing occlusal forces is crucial for periodontal health.
- Existing methods for evaluating occlusal load lack objective quantification.
- The Periotest device offers a novel approach to measure occlusal dynamics.
Purpose:
- To establish Periotest values for different occlusal states (disclusion, centric occlusion, maximum intercuspation, axial).
- To determine a quantitative, objectifiable parameter for the
- dimension of occlusion
- .
- To assess the functional load on the periodontium based on occlusal conditions.
Summary:
- Periotest values were measured in 102 subjects across 1769 teeth in various occlusal states.
- Teeth were analyzed based on antagonist contact, abrasion facets, and occlusal restorations.
- Comparative Periotest measurements in disclusion and maximum intercuspation provide a normal range for physiologic occlusal loads.
Impact:
- Introduces a quantitative parameter for assessing the
- dimension of occlusion
- and functional periodontal load.
- Occlusal restorations, particularly on premolars, showed significantly different Periotest values compared to natural surfaces.
- Axial measurements indicate a superior shock-absorbing capacity of the periodontium compared to horizontal measurements, aiding in precise occlusal restoration adjustments.
