Comparing the Clinical Accuracy of Orientation Jaw Relation Recorded with Various Commercially Available Facebows-An in Vivo Study

Articulators and facebow are an integral part of prosthodontics therapy that ensures accurate reproduction of the patients maxillomandibular relationship. Facebow has been regarded as as indispensable accessory of semi adjustable articulators for transferring the maxillary relation to the articulator. Facebows are of two basic types. They are Arbitary and the Kinematic facebow. Arbitrary facebows are popular, their level of accuracy has always been a topic of debate for reasons such as variable anterior reference points, operator variability and arbitrary posterior point of reference. There are numerous studies that have evaluated the accuracy of a facebow. The present study aims to the study and compare the clinical accuracy of orientation jaw relation recorded with various commercially available facebows.
