Abstract: Purpose: The aim of this study was to development a clinical assessment of the precision of the following three different mounting techniques on a semi-adjustable articulator: arbitrary facebow, Camper’s plane, and plane parallel to the ground for fabricating occlusal splints.
Methods: Ten male and female young adults with complete dentition and no signs or symptoms of temporomandibular disorders were selected. For each individual, three different mountings of the maxillary casts were made in three semi-adjustable articulators, one for each technique assessed. To mount the mandibular casts, a single interocclusal record was made using polyvinylsiloxane record material. An acrylic template was made for each technique, on which a flat plane was made with self-polymerizable acrylic resin. The three occlusal splints were adjusted in a blind manner. Adjustments were made until points of contact similar to those obtained in the articulator were achieved. The occlusal splints were digitized after achieving the points of contact obtained in the articulator and after each adjustment. A comparison was made between the number of points of contact of each mounting obtained in the articulator at the time of placement, after the third adjustment, and the total number of adjustments required.
Results: The results showed that there was no significant difference among the three methods in making the occlusal splints.
Conclusion: Therefore, it is concluded that the three mounting techniques are satisfactory for fabricating occlusal splints.
