Abstract:

The primary use of pantography is to program an articulator so the articulator movements will more closely harmonize with the patients mandibular movements. The objective of this four-part investigation was to assess and compare the accuracy, repeatability, and procedure time of the optoelectronic computerized pantograph, the electronic stylus computerized pantograph, the mechanical pantograph, and the kinematic face-bow. This study was performed in vitro on three identical semi- adjustable articulators Denar Mark II, Teledyne Water Pik. A kinematic face-bow Denar Axis Locator, Teledyne Water Pik and optoelectronic pantograph Condylocomp, Dentron performed the transverse horizontal axis investigations. A mechanical Denar, Teledyne Water Pik, electronic-stylus Pantronic, Teledyne Water Pik, and optoelectronic Condylocomp, Dentron pantograph performed protrusive condylar path, progressive mandibular lateral translation, and immediate mandibular lateral translation determinations. The experimental design restricted the patient variables associated with these methods. An initial evaluation was performed to identify the measured mid-point of the articulator condyles. Next, the Stuart axis locator Stuart Gnathologic Instruments was used to determine the transverse horizontal axis of each articulator. The kinematically located transverse horizontal axis and the measured center of the condylar ball were identical.
