From Wikipedia, the free encyclopedia. If the purpose of the facebow and articulator is to faccebow accurate movements, then the representation of the condylar position is important.

The patient must be in the same position that was used when the axis was marked to prevent skin movement from introducing any inaccuracy.

I was completely confounded by the need for anything else when I graduated from dental school. Responses Carmen What is mandibular hinge axis?

This placement generally locates the rods within 5 mm of the true centre of the opening hinge axis of the jaw [1]. Concise Prosthodontics- E Book: For this reason the study included only female patients, that is, patients more often affected with the abovementioned problem. Examined group characteristics allowed achieving an unequivocal and reliable outcome. Its purpose is to transfer functional and aesthetic components facbow patient’s mouth to the dental articulator.

U-shaped frame – forms the main part of the frame with remaining components attached to it by clamps.

Why Do I Need A Facebow?

It should be emphasized that in each registration the authors tried to minimize the distance between teeth arches. One of the popular assessment methods is the use of facebows, allowing for three-dimensional diagnostics and enabling the upper jaw cast to be correctly placed in the articulator, as well as providing the user with the precise data necessary during the adjusting procedure [ 5 — 7 ].


The experiment showed that the values obtained for the condylar path inclination vary significantly depending on the device used. The writing element followed the condyle and recorded the path onto the card.

While the concepts may seem complex, the reality is that using a facebow with a semi-adjustable articulator will ultimately save you time, money and help improve patient satisfaction.

Hinge axis was aligned individually in each case. When the mandible makes a strictly rotational movement, the stylus will remain stationary if aligned with the actual axis of rotation.

Why do I need to make life more complicated?

Retrieved 11 February A face-bow is a dental instrument used in the field of prosthodontics. Kinematic facebows are used to locate terminal hinge axis of condylar rotation. We also use a semi-adjustable articulator rather than a fully adjustable instrument for the same reasons. This feature allows applying the facebows in fixed and removable dentures manufacturing. It should be noted that extensive menu in the electronic device and the visualization of the mandibular movements on a desktop allows full three-dimensional diagnostics of the temporomandibular joints moves, which is the great clinical value.

Gupta, Ruchi 2nd ed. The kinematic facebows allow for individual dynamic evaluation of occlusion in relation to hinge axis, by geometrically assigning the distances between the occlusal plane and the rotation axis and then transferring the clinical data to the articulator [ 89 ]. This article may contain an excessive amount of intricate detail that may interest only a particular audience. Frame extends from the region of TMJ or external acoustic meatus to a distance of inches in front of the face [1].

The reference point is used later for reproducibility. The CPI values measured during the study are presented in Table 1. The angle of the CPI was determined for each chart with a protractor and then averaged.

The Art and Practice of Dentofacial Enhancementvol. Introduction One of the prevailing problems of temporomandibular rehabilitation is the reliable evaluation of the dynamic relation between the occlusal surface and the condylar position [ 1 — 4 ]. If an accurately recorded facebow is utilized to mount upper casts, the dentist and technician will be able to assess any cant or occlusal plane irregularity relative to the horizontal plane.

This page was last edited on 4 Marchkinemaitc Thus, the arc indicates in what direction an adjustment should be made to the stylus position. A less precisely derived transfer would then lead to unacceptable errors and a compromised result. The total time to capture a facebow is less than five minutes, and especially when doing the last teeth in the arch or multiple teeth, can save considerable time and even remakes at restorative delivery.

View at Google Scholar R. Post a comment Name The kinematic systems provide precise and noninvasive diagnostics of temporomandibular joints movements and articular discs displacements [ 11 ]. The paraocclusal tray used by ARCUSdigma II was prepared each time by applying silicone on the occlusal surfaces tacebow incisial margins of lower teeth.
