- Abstract
Background: Precise occlusal restorations, both fixed and removable, require accurate occlusal records and a set of working casts, which should be mounted on a full-sized articulator, at least a semi-adjustable one. There is no perfect device that can duplicate the mandibular movements of a particular patient. The aim is to minimize the occlusal errors produced in the laboratory without adding any complicated and time-consuming procedures. Aim: The aim of the study was to compare the efficacy of the modified arbitrary facebow for recording the orientation jaw relation. Materials and Methods: A total of 90 undergraduate students Saveetha Dental College with prior experience in the orientation of a facebow were selected to orient the arbitrary facebow (UTS 3D by IVOCLAR VIVA DENT) and modified version of the same facebow. The students were divided into two groups. A single-blinded randomized control trial was performed. The time required to mount the facebow to the subject was recorded for both groups. The participants were randomly allocated into groups. Group (A) students received the conventional arbitrary facebow first to orient the facebow on the patient. Group (B) students received the modified arbitrary facebow first to orients the facebow for jaw relation. Results: Time taken to orient the conventional facebow ranged between 10 and 14 min with a mean value of 10 min 50 s, while time taken to orient the modified version ranged between 48 s and 1 m 53 s with a mean value of 1 min 24 s [Table 2]. Parallelism to the horizontal reference plane was verified by the second observer. Conclusion: Within the limitations of this study, a modified facebow was used to reliably reproduce the spatial orientation of the occlusal plane relative to the true horizontal plane with the patient in natural head position that corrects the occlusal plane record and develops a good concept of occlusion in planed restorations.
