SIMPLIFIED TAD MECHANICS FOR MOLAR UPRIGHTING NICOLA DERTON CONEGLIANO, ITALY INTRODUCTION Preprosthetic orthodontic treatment plays a fundamental role for adult malocclusion correction. Mandibular molar uprighting is a huge help to both the surgeon and the prosthodontist because it creates ideal conditions for prosthetic rehabilitation of edentulous areas. Conventional orthodontic appliances, when used traditionally, can present some problems that are detrimental to the malocclusion correction. These problems can include: molar extrusion, undesirable movements of an anchorage unit, a need for extended appliance wear, the need for auxiliary devices and/or a long treatment time. During the last several years, skeletal anchorage miniscrews have proved to be a reliable, efficient, and simple adjunct to any biomechanical system. The aim of this paper is to illustrate, by means of a case report, the guidelines for a simplified TAD approach to molar uprighting for prosthetic rehabilitation prior to restoration. CASE REPORT An adult woman presented with a Class I malocclusion and several missing teeth. (Figs. 1, 2, 3) The mandibular right second molar exhibited mesial inclination. After consultation with the prosthodontist, the plan that was developed was to insert two implants in the mandibular left quadrant and one implant in the mandibular right quadrant. Prior to implant insertion in the mandibular right quadrant, the mesioangular inclination of the mandibular right second molar had to be corrected. (Figs. 4, 5) Because of insufficient bony support, the orthodontic treatment plan called for TAD anchorage in order to simplify the mechanics. To accomplish molar uprighting, a 1.5 mm x 9 mm miniscrew (Spider C2HDC, Fig. 3 Fig. 4 Fig. 5 Sarcedo Italy) was inserted distal to the mandibular second molar and a metal button was bonded to the mesial surface of the molar. The force from the TAD to the inclined tooth was accomplished with an alastic chain. (Figs. 6, 7) To enhance the stability of the TAD, it was inserted in an outer oblique line to the retromolar area where thicker cortical bone can be easily found. The TAD was screwed deep into the bone in order to develop a vertical force vector system that would result in an intrusive effect on the molar. (The head of the TAD was more cervical than the application point on the tooth.) Fig. 6 Fig. 7 Fig. 1 Fig. 2 34
