Clinical Significance.—The templates offer a cost-effective method for reducing multiple teeth and inserting a metal-reinforced interimfixed prosthesis. The simplicity of the approach makes tooth preparation and delivery of laboratory-processed interim restorations easier and more predictable.

Temporomandibular Disorders Trismus device Background.—Trismus can develop after oral and maxillofacial surgery. Management is difficult, with lack of compliance with treatment contributing to the problem. Various mechanical aids have been developed to increase mouth opening but these are expensive, complicating routine use. A simple, inexpensive, and effective device was suggested. Methods.—The Patient Bite (Pat-Bite) consists of three or four tongue spatulas fastened at right angles above and below a 20 to 25-mL capacity syringe. Two elastic bands hold the tongue spatulas in place (Fig 1). One end of the spatula is placed in the mouth. The patient then presses on the other end, which lifts and opens the mouth more widely (Fig 2). Results.—Regular use of these devices by patients helps them to open their mouths to a much greater extent. Although not everyone may be able to use the device, it offers an effective method of treating trismus for many patients.

Clinical Significance.—Trismus can be challenging to manage, and the devices that have been developed are just too expensive for many patients. Patients also are notorious for not complying with the treatment. The device described is simple, easy to use, and apparently works for many patients.
