Clinical Performance of CAD/CAM Occlusal Splints Fabricated With or Without a Wax Bite Registration in Healthy Adults (Splint)
Clinical Performance of CAD/CAM Occlusal Splints Fabricated With or Without Wax Bite Registration: A Randomized Crossover Clinical Trial
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

Descrição detalhada
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.

Experimental: Sequence B
Participants receive a CAD/CAM occlusal splint fabricated using a virtual increase of the vertical dimension (without a wax bite registration) for 3 weeks, followed by a CAD/CAM occlusal splint fabricated using a conventional wax bite registration for 3 weeks.
|
Intervention 1: CAD/CAM occlusal splint fabricated using a virtual increase of the vertical dimension CAD/CAM-milled occlusal splint fabricated from PMMA using a fully digital workflow.
The splint is designed by virtually increasing the vertical dimension based on the participant's maximal intercuspation, without the use of a conventional wax bite registration.
Participants will wear the splint overnight for 3 weeks (minimum 6 hours per night).
Intervention 2: CAD/CAM occlusal splint fabricated using a conventional wax bite registration CAD/CAM-milled occlusal splint fabricated from the same PMMA material using a conventional wax bite registration to determine the vertical dimension and occlusal relationship during the digital design process.
Participants will wear the splint overnight for 3 weeks (minimum 6 hours per night).
