Abstract
BackgroundThis study aimed to demonstrate that the material of the occlusal splint can be chosen according to the needs of individual patients and contribute to the knowledge of the wear rate of these materials.MethodsIn this study, four occlusal splint materials (Sr Ivocap Heat Cured, Valplast, SR Ivocap Elastomer and Eclipse) and three antagonists (natural tooth enamel, inCoris TZI and IPS e.max Press ceramic materials) were used. Each wear test was performed using a chewing simulator (n = 16; test load: 50 N; number of cycles: 10,000, 20,000 and 30,000; continuous rinsing with water at 30 °C for the wet condition). The Shapiro Wilk test was used for normal distribution suitability. Antagonist on average wear quantities both main effects and interactions of material, cycle and condition factors were investigated by Univariate variance analysis. Multiple comparisons were examined using the Games-Howell test.ResultsThere was a statistically significant effect of the difference in materials on the amount of wear (p < 0.001). Furthermore, there was a statistically significant difference among the mean values of all materials (p > 0.001). The highest mean value was obtained with Eclipse (0,318 μm3), and the lowest mean value was obtained with Valplast (0,134 μm3).ConclusionOur study found differences in the in vitro wear rate among various occlusal splint materials.
Highlights
This study aimed to demonstrate that the material of the occlusal splint can be chosen according to the needs of individual patients and contribute to the knowledge of the wear rate of these materials
The material type of occlusal splint or the antagonist surface influence the wear rate; but how long and how much? A variety of materials are currently used for fabricating occlusal splints
The lowest mean values were observed in the InCoris TZI C -Valplast interaction (0,09 μm3)
Summary
This study aimed to demonstrate that the material of the occlusal splint can be chosen according to the needs of individual patients and contribute to the knowledge of the wear rate of these materials. Occlusal splints are commonly used to protect dentition from parafunctional forces. Occlusal splints are often preferred for treating and preventing temporomandibular joint disorders (TMD) a condition with varying degrees of presentation and severity [1]. Occlusal splints are removable appliances that are usually fabricated from acrylic resin for use in the upper or lower jaw [2]. The wear of occlusal splints over time is of clinical concern. The material type of occlusal splint or the antagonist surface influence the wear rate; but how long and how much? A variety of materials are currently used for fabricating occlusal splints.
