Occlusal Splints or Botulinum Toxin?

Occlusal splints are appliances that were usually applied to the upper jaw and covering all teeth and they are made of autopolymerizing acrylic resin. It is produced by using 2 mm thick hard acrylic between the maxilla and mandible as defined by the Okeson.

We diluted 100-U freeze-dried BTX-A with 1.0 milliliters of sodium chloride, resulting in a dose of 1.0 U per 0.1 mL. We administered all skin injections by using a 1-inch 30-gauge needle. Patients were placed with the Frankfurt horizontal plane parallel to the floor.
