OBJECTIVE: This study examined the question of taking anterior occlusal radiographs (AO) in addition to a dental panoramic tomogram (DPT) using the Planmeca PM Proline CC. DESIGN: Retrospective single centre study. SETTING: Dental hospital radiology department. SUBJECTS: 100 pairs of DPTs and AOs which had been requested for orthodontic assessment were examined between April and July 1995. All DPTs were taken on a Planmeca PM Proline CC machine. RESULTS: The AO was assumed to be the gold standard and the diagnostic validity of the DPT can be assessed using values of sensitivity and specificity. 21% of DPTs were identified as requiring a supplementary radiograph to clarify the image of the anterior maxilla. CONCLUSIONS: A DPT machine with an adjustable focal trough has significantly reduced the need for supplementary AO radiographs. The AO is indicated when there is abnormality in the premaxilla or where dental malocclusion prevents ideal positioning of the patient in the machine.
A simplified technique is described for use when waxing pontics to a fixed partial denture which ensures accurate pontic placement without attaching the pontic to the retainers until late in the fabrication process. This technique allows easy access to the proximal contours and margins of the retainers and to proximal and gingival contours of the pontic while maintaining an accurate occlusal relationship.
Although the oncologic validity and perioperative complications of midline mandibular osteotomy are well described, little attention has been directed toward the long-term functional problems that may be associated with its use. Thirty-one patients who had undergone this procedure were examined to assess postoperative sensation, temporomandibular joint (TMJ) function, occlusion, and cosmesis. The majority (27 of 31) patients had some sequelae but these were minor in nature. Twenty of 31 patients had abnormal sensation, 24 of 31 noted a changed occlusion, and 15 of 31 had signs or symptoms of TMJ myofascial pain. Although patients should be advised of the potential for functional problems with this procedure, they can be reassured that these are likely to be relatively minor in significance. If technically feasible and if an exact restoration of occlusion is a priority, a prefabricated lingual splint should be used.
