Oclusal Splint - Bruxism - Bite Splint from Michigan

What are the indications for flexible and rigid occlusal splints?

The use of flexible occlusal splints is indicated only in cases where the patient engages in activities that pose a risk of mechanical trauma, which could cause fractures of the teeth. Engaging in sports generally requires the use of these flexible occlusal protectors. In such cases, the device should cover the entire dental element to protect even the soft tissues of the lips, cheeks, and tongue if they are compressed against the teeth.

For the treatment of joint and muscle disorders involving the masticatory system, rigid occlusal splints are necessary.

The most important characteristics of the materials used in the construction of myorelaxant occlusal splints are strength and mutability. Strength is important to maintain the stability of occlusal contacts achieved initially during the plate waxing process in the articulator. Mutability allows for adjustments after acrylicization, either by material removal or addition, to restore mandibular stability following possible changes in condylar positioning. The patient requires a rigid interdental support so they can comfortably swallow and guide mandibular movements.

The splint should function as if it were their own teeth, properly positioned. Ultimately, the treatment with occlusal splints aims to artificially create the ideal occlusion requirements for patients who, for one reason or another, cannot achieve them with their teeth in their current position.

This restoration of ideal occlusion promotes muscular rest and relieves tensions and compressions on joint tissues, thereby improving the condition and indicating stable orthopedic condylar position.
