简要总结
Occlusal splints are commonly used to manage sleep bruxism, temporomandibular disorders, and tooth wear. Traditionally, a wax bite registration is used during the fabrication of CAD/CAM occlusal splints to determine the vertical dimension and occlusal relationship. New digital techniques allow the splint to be designed without a wax bite registration by virtually increasing the vertical dimension based on maximal intercuspation.
This randomized crossover study compares these two fabrication workflows in healthy volunteers. Participants will wear both splints in random order. The study will evaluate patient-reported comfort and clinical performance, including occlusal contacts, force distribution, splint stability, and the occlusal adjustments required during insertion
详细描述
Occlusal splints are widely used in the management of sleep bruxism, temporomandibular disorders, and tooth wear. The increasing implementation of CAD/CAM technology has improved the efficiency and reproducibility of occlusal splint fabrication. Conventionally, the vertical dimension and occlusal relationship are determined using a wax bite registration. Recent developments in digital dentistry now allow the vertical dimension to be increased virtually based on the patient's maximal intercuspation, eliminating the need for an additional wax bite registration.
Although both fabrication workflows are currently used in clinical practice, there is limited clinical evidence comparing their performance. It remains unclear whether omitting the conventional wax bite registration affects the initial clinical performance of CAD/CAM occlusal splints at insertion, before any occlusal adjustments are performed. Potential differences may exist in patient comfort, splint stability, occlusal contacts, force distribution, and the number of occlusal adjustments required. In addition, little is known about differences in patient-reported outcomes, including comfort, perceived occlusion, stability, and overall satisfaction during the period of splint use.

结局指标
主要结局
Participant-reported comfort
时间窗: From enrollment to the end of treatment at 7 weeks
Self-reported wear comfort by filling in a questionnaire. This scale measures the comfort of the occlusal splint (0-10), where "very uncomfortable" represents the worst experience (lowest score) and "very comfortable" represents the best experience (highest score). Minimum Value: very uncomfortable, Maximum Value: very comfortable. Higher Scores Mean: better comfort (more comfort)
