Background Adolescent internal condylar resorption (AICR) is a temporomandibular joint (TMJ) pathology that develops predominately in teenage females during pubertal growth (onset between ages 11 and 15 years), with a distinct clinical, radiographic, and magnetic resonance imaging (MRI) presentation. Clinical and imaging presentation The condition usually occurs bilaterally with: (1) Progressive retrusion of the mandible; (2) High occlusal plane angle facial morphology; (3) Worsening Class II occlusion; and (4) TMJ symptoms such as pain, headaches, noises, etc. MRI imaging demonstrates decreased condylar head size and anterior disc displacement. Treatment protocol AICR can be successfully treated when the condyles and discs are salvageable with the following surgical protocol: (1) Removal of bilaminar tissue surrounding the condyle; (2) Reposition the disc with the Mitek anchor technique; and (3) Orthognathic surgery to advance the maxillo-mandibular complex in a counterclockwise direction. Conclusion AICR can be successfully treated using the specific protocol presented herein to provide stable and predictable outcomes.
Objective To evaluate treatment outcomes for patients with TMJ adolescent internal condylar resorption (AICR) treated by a specific surgical protocol, including: (1) Removal of bilaminar tissue surrounding the condyle, (2) Articular disc repositioning with Mitek anchor technique, and (3) Concomitant orthognathic surgery. Methods This study evaluated 24 AICR patients treated by the specific surgical protocol with clinical subjective and objective examinations and lateral cephalogram assessments for surgical changes and long-term outcomes. Results Mean age at diagnosis was 16.5 years, and mean follow-up was 30.3 months. All 24 patients had significant reduction in TMJ pain, facial pain, and headaches, with improvement in jaw function, diet, and disability. Cephalometric analysis showed significant surgical changes but good long-term occlusal and skeletal stability. Conclusion Patients with AICR treated with the specific surgical protocol demonstrated good skeletal and occlusal stability as well as improvement in TMJ pain, headaches, jaw function, diet, and disability.
Introduction: Adult and young adult patients have been increasingly seeking for orthodontic treatments and almost all of them want it to be done by an aesthetic appliance with maximum invisibility. The lingual technique has emerged in the late 1970s and has now become a very viable alternative to perform orthodontic treatments, however, many cases of treatment or retreatment involve correction through orthognathic surgery. The surgical technique is more sedimented and simplified as a great aid in the correction of skeletal discrepancies. Objectives: This article aims to show the correction of malocclusion and discrepancy between dental arches, with the lingual orthodontic technique and the surgical association. Conclusion: It is possible to provide to the patient an adequate correction of malocclusion, maintaining the desired aesthetics through the lingual technique and orthognathic surgery
