Mandibular molar protraction with temporary anchorage devices.
351 P of mandibular molars is challenging because of the high density of mandibular bone. Anterior dental anchorage is often inadequate to protract even a single first molar without reciprocal retraction of the incisors or movement of the dental midline. Furthermore, if the buccal and lingual cortical plates in the edentulous region have collapsed, safe and effective protraction may be impossib...
متن کاملFinite element analysis of mandibular molar protraction mechanics using miniscrews.
BACKGROUND/OBJECTIVES The aim of this study was to determine the most desirable force system to achieve molar protraction from an interdental miniscrew minimizing side-effects. Several iterations of force delivery were simulated through variations in the height of a miniscrew, length of a molar extension arm, and incorporation of a lingual force. MATERIALS/METHODS A three-dimensional mesh mod...
متن کاملEffect of removing an impacted mandibular third molar on the periodontal status of the mandibular second molar.
PURPOSE The aim of this study was to evaluate the change in the periodontal status of mandibular second molars after surgical extraction of adjacent impacted lower third molars. MATERIALS AND METHODS The study was based on a 1-year follow-up of 48 patients (20 men and 28 women) recruited consecutively after the extraction of an impacted lower third molar. Panoramic radiographs were obtained a...
متن کاملEtiological factors in second mandibular molar impaction
OBJECTIVES The impaction of the second mandibular molar (MM2) has recently become more prevalent. Several etiological hypothesis have been proposed to investigate the association between skeletal features and impaction of MM2. The aims of this study were to analyze the skeletal features in patients with MM2 impaction and the association between arrested eruption of MM2 and the presence of the t...
متن کاملMiddle Mesial Canal In Mandibular Second Molar
As right quoted by MT Barrett, “of all the phases of anatomic study in human system, one of the most complex is the pulp cavity morphology.” The external and internal morphology of the tooth varies from person to person. For each tooth in permanent dentition, there is a wide range of variation reported in literature with the respect to frequency of occurrence of the number and shape of the cana...
