ABSTRACT 1. Muscle seated centric registration is a reproducible method of obtaining centric relation (Wood, 1994). 2. The muscle-seated CR record provides a consistent, accurate, less technique-sensitive CR record of condylar position.

    ABSTRACT: Ths split cast technique has been advocated as a useful clinical tool for checking the reproducibility of jaw registrations. As originally described it requires the use of a kinematic face bow. Since the arbitrary axis used with the Whip-Mix face bow has been demonstrated to be close to that of the kinematic axis, it is feasible that the split cast technique could be used with such a face bow. Casts of ten subjects were mounted with retruded jaw registrations, made at different degrees of vertical separation. The upper casts were mounted using both kinematic and arbitrary face bow transfers, and the accuracy of mating of the split components measured.With the arbitrary face bow, the components of the split cast system only mated when repeated registrations were of exactly the same thickness, i.e. the same vertical dimension. Small differences in vertical dimensions produced the largest errors at the split. Any slight variations in the thickness of the retruded registrations will therefore invalidate the use of the split cast method in conjunction with an arbitrary face bow.The importance of the correct spatial relationship of mounted dental casts for the adequate diagnosis and treatment of a variety of oral and associated masticatory system disturbances is well documented (Lucia, 1961; Lucia, 1964; Celenza, 1973). However, accurate execution of the clinical and laboratory stages is necessary if the required information is to be obtained from articulated casts.

    ABSTRACT: The retruded contact position (RCP) is an important maxillomandibular relation in restorative dentistry. This review will describe RCP and consider its importance and use in the restorative dental treatment of the dentate and edentulous subject. A comparative account of the various mandibular guidance methods used to obtain a RCP record will be presented, followed by recommendations for fixed and removable clinical prosthodontic practice.

    ABSTRACT: The purpose of this study was to assess our method of analytic model planning in achieving a planned maxillary advancement for the correction of a dentofacial deformity. A consecutive series of 20 patients who underwent bimaxillary orthognathic surgery, at a minimum, were included in the study group. For each study subject, consistent analytic model planning with splint fabrication was used to establish the desired horizontal repositioning of the maxilla. Using preoperative and 5-week postoperative lateral cephalometric radiographs, an analysis was designed to assess the difference between the planned and actual advancement of the maxilla. The average difference between the planned and actual 5-week postsurgical advancement of the maxilla was 0.6mm (range 0.2-1.0, P>0.05). There was a strong correlation between the two data sets (R=0.96). The results of the study indicate that the described method of analytic model planning is reliable (within 1mm) in achieving the planned level of maxillary advancement in bimaxillary orthognathic procedures.
