Natural Dentition, Prosthesis and Antagonist Wear 3D Analysis

NCT05637619 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 36

Summary

Wear resistance is one of the most important physical properties of teeth, and wear resistance of zirconia against artificial acrylic, enamel and composite resin denture teeth has not been clearly established.

Implant-supported dental restorations present a higher threshold for occlusion perception when compared to natural teeth, which can occlusal overload mechanisms or lead to wear of rehabilitation materials or the antagonist arch.

In clinical conditions, however, many other factors influence the complex interaction between dental enamel and opposing substrates: patient-related factors such as dietary habits, dysfunctional occlusion, masticatory forces, and bruxism contribute to accelerated enamel loss of antagonist teeth.
