Stone model mounting is an inevitable process to set up model teeth and fabricate transfer jig for lingual orthodontic treatment. Facebow transfer is the first procedure for mounting a model on an articulator. Facebow transfer is a process for constructing a specific reference plane to position a maxilla in three dimensional space. Therefore, it is very important to transfer a maxilla to an articulator correctly and reproducibly. FH plane has been used as a basic reference for diagnosis and treatment planning for long time. Moreover, we have usually used it for mounting a model on an articulator. However, FH plane has a limitation that it can be variable and changeable according to the vertical position of orbitale and porion inter-individually. Therefore, we clinician need a reproducible and reliable reference for facebow transfer. True horizontal plane as an alternative can be a good reference to perform above the procedure. The steps for facebow transfer using true horizontal plane based on natural head position will be described step by step in this article.
