The terminal hinge axis (THA) is the axis around which the mandible rotates when the mandible is in centric relation. The purpose of facebow is to record the patients THA and transfer it to the articulator so that it coincides with the arc of closure/hinge axis of the articulator. When the THA coincides with the hinge axis of the articulator, it is presumed that the restorations will be free of interferences and there will be stability in the stomatognathic system.
With the advances in technology and with the assimilation of this technology in dentistry, it is indeed amazing to visualize the virtual facebow transfers and virtual articulators.
Virtual reality is a computer-based technology linked with the future of the dentistry-dental practice. Virtual reality leads us to navigate and view a world of three dimensions in real time with 6 degrees of freedom.
Using a virtual procedure, the maxillary digital cast is transferred to a virtual articulator using reverse engineering devices. The following devices necessary to carry out this protocol are an intraoral scanner, a digital camera, and a specific software. Results prove the viability of integrating different tools and software and of completely integrating this procedure into a dental digital work flow.
It provides a quantifiable, repeatable, and reliable method of transferring the location of the maxillary dental arch from the patient directly to a virtual articulator and allows dentist and the dental lab technician to work in a fully digital environment without having to mount a stone cast on a mechanical articulator.
The virtual articulator is one such application in prosthetic restorative dentistry based on virtual reality that will significantly reduce the limitation of the mechanical articulator and by simulation of real patient data, allows analysis of digitized casts with regard to static and dynamic occlusion as well as jaw relation.
Virtual interocclusal records are used to orient the maxillary and mandibular casts in horizontal jaw relation.
With the advent of digital technology in prosthodontics, it is interesting to note how technology can be integrated toward planning and treatment and hopefully they become affordable to the dentists so that the process of treatments become less time-consuming and more efficient.
