• Three-Dimensional Photoelastic Stress Analysis on Posterior Hybrid Ceramics Bridge Restorations.

抄録

Hybrid ceramics meet high esthetic requirements. However, more information on application to the bridge still needed. This three-dimensional photoelastic study was conducted to analyze the stress distribution of hybrid ceramics bridge.<BR>Two types of bridge were compared. Type I was consisted of hybrid ceramics alone, while Type II had a metal frame inside. The bridge models were cut into three parts, buccal, central and lingual. The results were as follows:<BR>1. Maximum tensile stress appeared in the distal connector in Type I.<BR>2. Tensile stress appeared in the distal connector decreased in Type II.<BR>3. In both types, compressive stress closely appeared in both connectors.<BR>This means that the connectors have complicated distributions and different types of stress.<BR>4. In all three parts, the gingival area showed higher maximum shearing stress concentration than in the occlusal surface where loading applied.
