  • Title: Effects of occlusal adjustment on the periodontal condition and on the symptoms of masticatory dysfunction in patients treated with fixed prosthesis--a one-year follow-up study.

    Journal: J Oral Rehabil; 1986 Nov; 13(6):509-19. PubMed ID: 3467045.
    Abstract:
    A total of fifty-nine patients treated with a fixed prosthesis 4 years previously were recalled for a clinical and radiological examination. The subjects studied consisted of two groups: in group A the teeth of the patients with TMJ symptoms were selectively ground, whereas no grinding was performed in group B. At the first examination, occlusal interferences were found in 43.0% of the crowns and in 29.0% of pontics in group A before occlusal adjustment. At the second examination 1 year later, the percentage of occlusal interferences was decreased in this group (33.0% of the crowns and 25.8% in the pontics). In group B no changes in occlusal interferences were found after the 1-year follow-up period. The results of the investigation suggested that the frequency of interferences related to occlusal adjustment is important and the effect of occlusal adjustment to periodontal condition and TMJ symptoms is beneficial.
