Cirurgia ortognática associada á cirurgia das ATMs acometidas por artrite reumatóide ou osteocondroma

Can cone-beam computed tomography superimposition help orthodontists better understand relapse in surgical patients?

This case report describes the interdisciplinary treatment of a 19-year-old Brazilian man with a Class I malocclusion, a hyperdivergent profile, an anterior open bite, and signs of temporomandibular joint internal derangement. The treatment plan included evaluation with a temporomandibular joint specialist and a rheumatologist, orthodontic appliances, and maxillomandibular surgical advancement with counterclockwise rotation. Cone-beam computed tomography images were taken before and after surgery at different times and superimposed at the cranial base to assess the changes after orthognathic surgery and to monitor quantitatively the internal derangement of the temporomandibular joints and surgical relapse. Our protocol can improve the orthodontist's understanding of surgical instability, demonstrate the clinical value of cone-beam computed tomography analysis beyond the multiplanar reconstruction, and guide patient management for the best outcome possible.

Estabilidade sagital da condiloplastia associada à cirurgia ortognática para o tratamento do osteocondroma mandibular

The aim of this study was to evaluate the stability of the conservative condylectomy technique and articular disc repositioning as the surgical treatment approach for management of mandibular condylar osteochondroma, with appropriate Orthognathic surgery. Fifteen patients (12 females and 3 males), average age of 32.3 years (range, 13 to 56 years), with unilateral active osteochondroma of the mandibular condyle were analyzed. All patients underwent conservative condylectomy, recontouring of the remaining condylar neck stump and articular disc repositioned and indicated orthognatic surgical procedures. Average post surgical follow-up was 19 months. Each patient's lateral cephalograms were traced at 3 intervals (presurgery, immediate post surgery and long-term follow-up). Immediate after surgery the oclusal plane angle decreased -2.8 ± 4.5o, the maxillomandibular complex rotated counter-clockwise with advancement at menton 5.3 ± 5.6 mm, pogonion 5.0 ± 5.1 mm, B point 3.4 ± 4.2 mm and A point 1.0 ± 1.5 mm. The long-term follow-up showed significant changes in overbite (-0.6 ± 0.5 mm) and SNGoMe (0,93° ± 1,53°). Horizontally and vertically small instabilities occurred in Me (-1.21 ± 1.94 mm) and PNS (-1.48 ± 1.67 mm) respectively. The treatment protocol studied produced counterclockwise rotation and maxillofacial mandibular advancement. The long-term follow-up showed solid dental and skeletal stability with horizontal instability of Me and PNS in the vertical direction.

In vitro biomechanical comparison of six different fixation methods following 5-mm sagittal split advancement osteotomies

The sagittal split ramus osteotomy (SSRO) is a surgical technique used widely to treat many congenital and acquired mandibular discrepancies. Stabilization of the osteotomy site and the potential for skeletal relapse after the procedure are still major problems. The aim of this study was to compare the mechanical stability of six methods of rigid fixation in SSRO using a biomechanical test model. Sixty polyurethane replicas of human hemimandibles were divided into six groups. In group I, the osteotomies were fixed with two four-hole titanium miniplates; in group II, with one four-hole miniplate; in group III, with one four-hole miniplate + a bicortical screw; in group IV, with a grid miniplate; in group V, with a four-hole locking miniplate; and in group VI, with a six-hole miniplate. A linear load in the premolar region was applied to the hemimandibles. The resistance forces (N) needed to displace the distal segment by 1, 3, and 5 mm were recorded and the data transmitted from the load cell to a computer. One-way analysis of variance with Tukey's post hoc test was performed to compare the means between groups. For the three displacement conditions, there was a strong tendency for the 2.0-mm plate + screw and the grid plate to have higher values.

Maxillo-mandibular counter-clockwise rotation and mandibular advancement with TMJ Concepts (R) total joint prostheses Part I - Skeletal and dental stability

The purpose of this study was to evaluate skeletal and dental stability in patients who had temporomandibular joint (TMJ) reconstruction and mandibular counterclockwise advancement using TMJ Concepts total join, prostheses (TMJ Concepts Inc. Ventura, CA) with maxillary osteotomies being performed at the same operation. All patients were operated at Baylor University Medical Center, Dallas TX, USA, by one surgeon (Wolford). Forty-seven females were studied; the average post-surgical follow-up was 40.6 months. Lateral cephalograms were analyzed to estimate surgical and post-surgical changes. During surgery, the occlusal plane angle decreased 14.9 +/- 8.0 degrees. The maxilla moved forward and upward. The posterior nasal spine moved downward and forward. The mandible advanced 7.9 +/- 3.5 mm at the lower incisor tips, 12.4 +/- 5.4 mm at Point B, 17.3 +/- 7.0 mm at menton, 18.4 +/- 8.5 mm at pogonion, and 11.0 +/- 5.3 mm at gonion. Vertically, the lower incisors moved upward -2.9 +/- 4.0 mm. At the longest follow-up post surgery, the maxilla showed minor horizontal changes while all mandibular measurements remained stable. TMJ reconstruction and mandibular advancement with TMJ Concepts total joint prosthesis in conjunction with maxillary osteotomies for counter-clockwise rotation of the rnaxillo-mandibular complex was a stable procedure for these patients at the longest follow-up.
