However, when bad maxilomandibulare re- lations harm facial aesthetics, the orthodontic treatment’s objectives are to improve the aesthetic facial harmony and to correct the occlu- sion and re-equilibrate its functions. To achieve such aims, several thera- peuticstrategiescanbeused,suchas functional orthopedics, orthodontic- surgical treatment and dental ex- tractionamongothers. When extractions are chosen as the treatment strategy, the amount of retraction of the anterior teeth is very important to get significant al- terationswhenrepositioningthelips andtheskinprofile.Inthisapproach, the loss of anchorage becomes un- desirable because the maximum retraction of the anterior teeth is key to getting the biggest changes in the profile. Thus, all the anchorage con- trol strategies are important, such as extraordinary devices, intermaxil- lary elastics, transpalatal bars, Nance buttons, lingual arches, and ortho- dontic mini-implantations among others. Some of these alternative cosmeticsinconvenientlyrelyonthe cooperation of the patient for thera- peuticsuccess. In most cases, a successful ortho- dontictreatmentdependsoncareful planning of the anchorage (one of the factors that determines the suc- cess or failure of many treatments). Burstone’s Segmented Arch Tech- nique (BSAT) recommends the plan- ning of orthodontic treatment with a biomechanical foundation and the definition of the ideal system of forces for each clinical situation. The dental movement becomes predict- able when the physical concepts of the mechanics are known and are applied to the biology of the dental movement. With the evolution of This clinical case confirms that the Segmented Arch Technique, suggested by Burstone at the end of the 1960s, allows for effective control of the anchorage without the need for any cooperation on the part of the patient. Differential M/F ratios used on the anterior and posterior segments allowed for a large retraction of the anterior teeth, thereby reaching the treatment objectives: significant improvement of the facial profile, and aesthetic and functional occlusion. Therefore, the use of TAS type A handles is an excellent mechanical option in orthodontic treatment with extractions when maximal retraction of the anterior segment is desired to promote extensive and important changes in the tegumental profile.
