Conventional vs Digital CAD/CAM Splints for Bruxism

Randomized Cross-clinical Trial Comparing Precision of Conventional Stabilization Splints (Michigan Type) Versus CAD/CAM Splints With Fully Digital Flow

This is a randomized controlled trial with a crossover design, which intends to enroll 20 adult patients aged between 20 and 55 years with confirmed or probable sleep bruxism. Participants will be randomized to receive either a conventional stabilization splint or a CAD/CAM splint. Each patient will use one type of splint for 30 days, followed by a 15-day wash-out period, after which they will switch to the other type of splint. The study aims to compare the quality, precision, and comfort of the two types of occlusal splints. Outcomes will include manufacturing time, amount of in-mouth adjustments, adaptation, occlusal contacts, and participant satisfaction.

Inclusion Criteria:

• Adult patients aged between 20 and 55 years.
• Probable or confirmed diagnosis of sleep bruxism.
• No previous treatment with occlusal splints.
• Absence of periodontal diseases and/or dental fractures.
• Patients must have a minimum of 28 teeth.

Exclusion Criteria:

• Patients with systemic diseases affecting the temporomandibular joint, such as rheumatoid arthritis, osteoarthritis, and osteoporosis.
• Chronic users of medications that may interfere with the study results, including analgesics, anti-inflammatory drugs, anxiolytics, antidepressants, and anticonvulsants.
• Patients with a history of temporomandibular joint surgery.
• Pregnant or breastfeeding women.
• Patients with severe dental misalignment or malocclusion that would affect splint fitting and evaluation.
