Computer-aided interactive indirect bonding.

INTRODUCTION: The introduction of the virtual occlusal set-up, limited to the permanent dentition with dento-dental and dento-alveolar discrepancies, based on the straight wire technique with final arches .020" x .025" ss in straight wire brackets .022" x .028" is an evolution of the 3D digital model with clinical impact. AIM: To present a computer-aided solution to orthodontic indirect bonding, allowing accurate positioning of straight-wire brackets based on a virtual occlusal set-up resulting from the treatment plan. MATERIAL AND METHODS: Computer-aided indirect bonding was applied in two cases: a Class II patient in the permanent dentition, crowding, rotation of upper and lower bicuspids and a Class I patient in the permanent dentition with already extracted 1.4, 2.4, 3.4, 4.4, severe crowding, rotation, arch form reduction. Speed brackets were utilized in both cases. RESULTS: In the first case the brackets' starting position on the patient corresponds to the final position on the virtual occlusal set-up. In the second case the resulting occlusion at the end of treatment corresponds to the final occlusion on the virtual occlusal set-up. DISCUSSION: The computerized tools employed in the process enabled precise bracket placement on the stone model. An algorithm from the virtual set-up is the determinant for the precision. CONCLUSION: Computer aided indirect bonding is a method of placing brackets precisely.

Digital treatment objectives: procedure and clinical application.

OBJECTIVES: the introduction of digital study models in the orthodontic practice changed the traditional stone gipsotec to a virtual gipsotec and the orthodontist has the possibility to see, immediately on the computer, this basic analysis with a great reduction of space and time. The aim of this study is to extend the use of digital models to the occlusal virtual set-up in 3D and have the orthodontist simulate and visualize the resulting occlusion from a suggested treatment plan for the malocclusion. METHODS AND MATERIALS: a case is presented where the treatment plan involvers extractions. The malocclusion is a Class II division 1 in the permanent dentition where an extraction treatment of 1.4, 2.4, 3.5 et 4.5 is planned: the final result shows the new occlusal relationship with proper anchorage management of the extraction spaces. From the primary silicon impression, a digital model is obtained followed by the virtual set up according the prescription of the treatment plan. More digital treatment objectives can be performed for the same malocclusion from the primary digital models, according to different treatment plans and the resulting occlusion visualized. RESULTS: the basic principle for the virtual occlusal set-up is the straight-wire system with the final position of the teeth resulting both from the bracket prescription and the final rectangular wire in a full slot engagement. CONCLUSIONS: the resulting dental arches show a correct arch form, arch coordination and a proper dental intercuspation. The results coming from different virtual simulations are analyzed; all these simulations need only one pair of impressions. Limits of this virtual method are that it can be used only in full permanent dentition and for cases of dento-alveolar or dento-dental discrepancy.

Distalization of maxillary molars using the speed system: a clinical and radiological evaluation.

AIM: To show how a self-ligating system can provide bodily movement of maxillary molars without extraoral devices or lingual appliances, reducing the need for patient compliance. The control of these tooth movements has been clinically and radiologically substantiated. METHODS: The biomechanical principles, patient selection, and steps of the treatment are described. Some reference points are shown on the lateral cephalogram for superimposition, to evaluate the sagittal, vertical, and angular changes. RESULTS: A number of cases have been treated with this technique, both distalization of maxillary first and second molars, with bodily movement and satisfactory anchorage management. CONCLUSION: The described system works efficiently, all with only intraoral appliances, but the use of light and continuous forces to reach bodily distal movement without secondary effects is mandatory. The described system also produces the desired objectives with a short treatment time.
