Registration and inarticulation of maxilla position with face - bow and headline systems, comparative analysis

Abstract

It is important to register and transfer the proper maxillary position for making precise restortaions. The aim of this study was to analize the registration and articulation of maxillary position using facebow and HeadLines systems. Both of methods were described and compared using two aspects - asymmetry of ears and presence of hinge axis. The clinical case demonstrated that using HeadLines maxillary and mandible models were slanted correctly in sagittal and coronal planes. Introduction. One of the main purposes of prosthodontics is to make accurace and well-fitted restorations that would also be harmless to the masticatory system. Even the smallest prosthetic intervention to dentition can negatively affect occlusion and the temporomandibular joint (TMJ). For making restorations, modern dentistry uses different skull reference lines and points that are determined for every patient individually. The maxilla is a fixed part of the skull base, and when the teeth of both jaws come into contact, the maxilla becomes related to the mandible so that the entire cranio-maxillary complex is articulated with a moving bone - i.e. the mandible.
