[The reproducibility of arrow-point registration in full-dentition subjects depending on the recording material].
The reproducibility of the intraoral central bearing point method was measured in 46 dentate subjects with a healthy stomatognathic system. Nine complete registrations were carried out on each volunteer, while three different materials were used for fixing the upper to the lower jaw. The occlusal records were examined in the condylar area on a specially designed articulator. Two therapists took part in this study. The shifts of the condylar spheres in all three spatial directions were found as follows: Ramitec 0.14 +/- 0.16 mm, Super-Bite 0.15 +/- 0.14 mm and Bite Compound 0.15 +/- 0.16 mm. The movements of the condylar spheres in space were calculated. They amounted to 0.28 +/- 0.23 mm when using Ramitec, 0.28 +/- 0.20 mm when using Super Bite and 0.31 +/- 0.23 mm when using Bite Compound. Statistically, the differences between the data of the three materials were not significant. Also, the results of our random sample were independent of the therapist.
