CHANGE OF POSITION OF CONDYLE WITHIN GLENOIDAL CAVITY IN PATIENTS CLASS II SKELETAL WITH DEEP BITE. Actas Odontol. [online]. 2017, vol.14, n.1, pp.43-49.

The purpose of this investigation is to determine the change of position of the condyle within the glenoid cavity in class II patients with deep bite after the use of a fixed anterior Acrylic and Metallic bite plane, which will be done with a sample of the 20% of a universe of 100 patients from Clinic of the Postgraduate School of the Faculty of Dentistry of the University of Guayaquil to demonstrate the changes that occur in the temporomandibular joint resulting from the new position adopted by the condyle due to the new mandibular posture by the use of the bite plane. These patients will be evaluated through cephalometric radiographs that will be taken in the course of the use of the anterior bite planes until the contact of the posterior segment of the dental pieces has been achieved where the change of position of the condyle will be taken into account And thus determine the stability to be achieved in the treatment. The results that presented the patients in the change of position of the mandibular condyle that they used plane of previous bite Metallic was positive in 100% of them, arriving at the norm of 32 + -2; While 69.23% of patients who used the anterior acrylic bite plane had a positive change and 30.77% were negative; Therefore it is concluded that with the Metallic anterior bite plane, greater accuracy is obtained in the position change of the mandibular condyle.
