paper_title: In vivo and in vitro evaluation of occlusal indicator sensitivity.

paper_content:

Abstract Statement of Problem. Indicators used to locate and eliminate occlusal disharmonies have not demonstrated specific sensitivity and reliability. Purpose. The sensitivity and reliability of articulating papers, foils, silk strips, and T-Scan systems used as occlusal indicators were investigated. The effect of saliva on the materials also was determined. Material and Methods. In the in vitro part of the study, a test model (mounted in an articulator and in a universal testing machine) was established with the use of maxillary and mandibular dentate casts. Articulating papers, foils, silk strips, and the T-Scan system were used to examine the loss of sensitivity of the recording materials after 3 consecutive strokes. The differences in the contact points of the test model determined by each of the recording materials were evaluated both in the articulator and in a universal testing machine. In the in vivo part of the study, occlusal contact recordings of 3 subjects were made before and after drying their mouths. The significance of the differences between the strokes repeated more than once was evaluated with the Friedman 2-way analysis of variance and Kruskal-Wallis tests. To examine the effect of the oral environment, the Wilcoxon matched-pairs signed-ranks test was applied. In all statistical analyses, the level of significance was α=.05. Results. The results demonstrated significant differences in the sensitivity of the recording materials tested ( P P P P Conclusion. Within the limitations of this study, the results indicated that multiple use of the recording materials tested may lead to inaccurate occlusal analysis results. It is recommended that the recording materials be used only once and that the teeth be dry during occlusal analysis. (J Prosthet Dent 2002;88:522-6.)

paper_title: Evaluation of three occlusal examination methods used to record tooth contacts in lateral excursive movements.

paper_content:

Abstract Accurate and repeatable methods for recording tooth contacts are required for the clinical management of problems related to occlusion. A thorough understanding of the materials and procedures used in these methods is important to achieve desirable results in the treatment of such problems. This study compared three occlusal examination methods to determine the influence of materials and procedures on the number of tooth contacts recorded. Tooth contacts were analyzed at two lateral mandibular positions with each method. It was found that the method that uses black silicone recorded the highest number of tooth contacts. Thus the most frequent type of occlusal pattern observed was full-balanced occlusion. This study suggested that the disparities of results reported in literature on occlusal contact patterns could be the result of the different materials and methods used for occlusal registration.
