RESUMO

During the process teaching/learning in Dentistry, the occurrence of adverse inclinations of the bite fork concerned to maxillary occlusal plane of patients are current during the face-bow taking performed by students. This study evaluated the influence of the inclinations of bite fork to anterior and posterior related to oclusal plane on mounting of the maxillary cast in arcon and nonarcon semiadjustable articulators. Twenty casts of the maxillary arch from twenty patients were obtained, on which two points were marked: one on the vestibular edge of the right canine and another on the vestibular edge of mesiovestibular cusp of the right first molar. The records in the bite fork were made in three positions: the bite fork parallel to the castss plane occlusal, inclined to anterior and to posterior (both 5°). Each position was repeated five times, being the articulator/face-bow set fixed in special support for photographic register. Each photograph was introduced in Auto CAD program, resulting in lines of references for the collection of five measures (one angular and four linear). The data were subjected to statistical analysis parametric (Analysis of Variance). The results showed no significant statistical difference for inclinations of the bite fork to both anterior and to posterior related to the castss occlusal plane for the arcon and nonarcon semiadjustable articulators. The work suggests that small inclinations of bite fork do not compromise the face-bow taking and its transfer for the semiadjustable articulators.
