Introduction: With the advent of the porcelain, the use of the polymers diminished despite their improved features and expanded clinical applicability. Purpose: The purpose derives from the fact that there are absolute indications for the use of polymers as veneering materials for the dental bridges in the everyday dental practice. Methods As the material we used 200 patients divided into two groups. First group was professional boxers with dental bridges veneered with chained-linear polymers and second group was patients with bruxism with dental bridges veneered with cross-linked polymers. The measurements of color stability, strength and endurance to masticatory pressure were in 3 intervals: beginning, after 18 and 36 months. Results: In the first group, there were 0 polymer discolorations on the first measurement and 15(15%), 20(20%) on the second and third measurement respectively compared to the second group with 0 discolorations on the first and second and 30(30%) on the third measurement. The polymer strength estimated with the number of fracture spots for the first group was 0 for on first and second and 10(10%) on the third measurement and for the second group was 0 for each measurement. Masticatory pressure endurance for the first group was f(x)=200,75N, f(x)=271,00N, f(x)=290,55N on the first second and third measurement respectively and for the second group was f(x)=190,55N, f(x)=261,00N and f(x)=280,55N on the first, second and third measurement respectively. Conclusion: The linear and cross linked polymers satisfy the requirements to be used as veneering dental materials with optimal values for color stability, strength and masticatory pressure endurance.
