The Limitations of Traditional Non-Digital Occlusal Indicators When Compared to the T-Scan Computerized Occlusal Analysis Technology

Abstract

The traditional occlusal indicators used in dental practice are articulation papers, shim-stock foils, elastomeric impression materials, and occlusal wax strips. These static dental materials have been widely believed to have occlusal force descriptive capability. However, modern material studies are challenging the widespread belief that occlusal indicator materials can measure differing occlusal force levels. This chapter evaluates the force reporting limitations of these static occlusal indicators and discusses how clinicians subjectively interpret their appearance characteristics to determine differing occlusal force levels. This chapter then compares these non-digital occlusal indicators to computerized occlusal analysis technology that records and displays precise, quantifiable, relative occlusal force variances and occlusal contact timing sequences. This digital data aids the clinician in making a more accurate occlusal analysis and can guide the clinician in the correction of occlusal contact force and timing abnormalities, thereby eliminating the subjectivity that is inherent in traditional occlusal indicator use.
