The accuracy of maxillary positioning using digital model planning and 3D printed wafers in bimaxillary orthognathic surgery.

Objective: Orthognathic wafers may be made using digital model movements and CAD-CAM technology. This paper analysed the accuracy of maxillary movements using this new process.

Design: Retrospective study of pre and post-operative cephalograms.

Spontaneous resolution of a periapical lesion during orthodontic treatment: a case report.

Unlabelled: Teeth with periapical lesions can undergo successful orthodontic treatment, but conventional protocols indicate that such teeth should be endodontically stabilized prior to such treatment. A case report is presented where such endodontic stabilization was not possible, yet a chronic periapical lesion resolved as orthodontic treatment progressed. This paper will discuss the possible causes of the initial lesion, and reasons why it resolved without endodontic treatment.
