The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: Abstract The present invention relates to a pressure-graded multilayer articulating film designed for simultaneous detection and semi-quantitative assessment of occlusal contacts in dental applications. Conventional articulating media are limited to indicating the location of occlusal contacts without providing information regarding the intensity of applied force, often leading to inaccurate occlusal adjustments. The proposed invention comprises a thin, flexible multilayer film mcorporating multiple pressure-sensitive dye layers, each configured to activate at distinct compressive force thresholds. The film includes a protective outer layer, sequential low, medium, and high-pressure microencapsulated pigment layers, and a flexible backing substrate. Upon occlusal loading, the microcapsules rupture selectively based on the magnitude of applied force, producing color-coded markings corresponding to varying pressure intensities. This enables clinicians to accurately differentiate between light, moderate, and heavy occlusal contacts, thereby improving precision in occlusal equilibration, prosthodontic adjustments, and implant restorations. The invention offers a cost-effective, chairside alternative to digital occlusal analysis systems, while maintaining minimal thickness to avoid occlusal interference. The pressuregraded articulating film enhances diagnostic accuracy, reduces clinical chairside time, and improves overall treatment outcomes in restorative and prosthodontic dentistry.
