Evaluation of wear behaviour of various occlusal splint materials and manufacturing processes
2022, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :These had various diameters, loads, and hardness compared to the enamel, which might result in inaccurate readings and did not fully simulate clinical conditions. Studies that used human enamel as the antagonists, particularly molar cusps (Benli et al., 2020; Lutz et al., 2019; Schulte et al., 1987; Wesemann et al., 2021), had different cusp tip sizes, which might result in inconsistency of the experimental results. There are five types of wear mechanisms available (sliding, rolling, impact, fretting and slurry wear), varying on the contact type; however, they do not represent scientifically standardised wear mechanisms (Kato and Adachi, 2002).
Evaluation of the mechanical properties and degree of conversion of 3D printed splint material
2021, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :The overall results demonstrated a significant difference between post-cured and non-post-cured specimens. This study was conducted isothermally at 37 °C in agreement with previous studies (Lutz et al., 2019; Schulte et al., 1987) since occlusal splints are not exposed to temperature changes intraorally as they are usually inserted in the patients’ mouth at night when there is no intake of hot and cold food or drinks. Post-curing is essential to provide high conversion for photopolymers used in 3D printing and to obtain superior mechanical properties (Steyrer et al., 2017).
Polymers for conventional, subtractive, and additive manufacturing of occlusal devices differ in hardness and flexural properties but not in wear resistance
2021, Dental MaterialsCitation Excerpt :However, a direct comparison between in-vitro and in-vivo wear is difficult due to varying parameters and loads. Comparable to the presented results, Schulte et al. showed no measurable enamel antagonist wear when protecting the teeth with PMMA splints [24]. In contrast to 3-body wear tests of restorative materials [25], occlusal devices are not exposed to abrasive intermediate substrates like food.
Fracture resistance and 2-body wear of 3-dimensional–printed occlusal devices
2019, Journal of Prosthetic DentistryCitation Excerpt :Brasseler GmbH & Co KG). For the 2-body wear analyses,30-32 impressions were made (Flexitime Fast and Scan; Kulzer GmbH) at 3 successive points in time (before mastication simulation, after 20 000 mastication cycles, and 120 000 mastication cycles). The impressions were digitized using a laser scanner (LAS-20; SD Mechatronik GmbH).
