Minimizing movement of an orbital prosthesis retained by an obturator prosthesis.

This article describes a procedure in which an obturator with an integrated spring-loaded rewinding device retains an orbital prosthesis. This system minimizes movement of the orbital prosthesis during mastication and thus prevents adhesive failure.

Coping with stress: its influence on periodontal disease.

Background: Various forms of stress behavior were documented and in patients with periodontitis their relationship with periodontal disease was investigated.

Methods: Eighty-nine patients with different forms of chronic periodontitis were included in this retrospective case-control study. They were all undergoing periodontal treatment at the Department of Dental Prosthetics, University of Graz, or a private dental practice.

A comparison of the muscular relaxation effect of TENS and EMG-biofeedback in patients with bruxism.

This study investigated effects of electromyographic (EMG) biofeedback (BFB) and transcutaneous electrical neuromuscular stimulation (TENS) on the EMG activity of the masticatory muscles and skin conductance level (SCL) of patients, suffering from myofacial pain syndrome. In the course of the investigation, EMG activity as well as the SCL was measured after a 20 min BFB or, respectively, after a myomonitor session in 20 patients and pre- and post-treatment values were compared. Results showed tendencies of decreased mean-EMG levels for both groups after the treatment sessions, with higher EMG values for the myomonitor group.
