The objective of this study was to evaluate the rates of relapse, temporomandibular joint (TMJ) changes or disease, and recurrence of idiopathic condylar resorption (ICR) and open bite following orthognathic surgery in patients with ICR. Six Class II patients (aged 19~51) who suffered from ICR and received orthognathic surgery on maxilla and mandible were evaluated. All 6 patients received Le Fort I osteotomy on maxilla. 5 patients received BSSRO with advanced genioplasty and fixation with Miniplate and 1 patient received Obwegeser-Dal Pont's method and fixation with APIS plate on mandible. Lateral cephalograms were taken at presurgical (T0), immediately post-surgical (T1) and 3 months post-surgical (T2), and 6 months post-surgical (T3) stages, and skeletal changes were analyzed with V-Ceph (CyberMed, Seoul, Korea) software. Age and sex, surgery method, fixation material, and post-operative complications of each patient were examined. Only one patient showed TMJ muscle-related disorder symptoms. Open bite recurrence was not observed in any of the 6 patients. Orthognathic surgery on maxilla and mandible shows no relationship with a recurrence of ICR or open bite.

“…Facial deformity and condylar resorption after orthognathic surgery showed a significant correlation, specifically, the height of the mandibular plane. In 6 of 8 selected studies (Hoppenrejis et al; Kerstens et al;Bouwman et al;Merkx & Van Damme;De Clercq et al;Hwang et al, 2004), 541 patients who have absolute mandibular deficiency (high mandibular plane angle), 118 (21.8%) showed CR. This correlation may be explained by the change of loading after the correction of this type dentofacial deformity.…”

“…In the past, many studies on this subject have been published (Phillips & Bell;O´Ryan & Epker;Arnett & Tamborello, 1990;Arnett et al, 1996aArnett et al, , 1996bBouwman et al, 1994;Merkx & Van Damme, 1994;Scheerlinck et al, 1994 close range from 15 to 35 years, females presenting a high mandibular plane angle with mandibular hypoplasia and a small posterior-to-anterior facial height ratio (Hoppenreijs et al;Kerstens et al;Arnett et al, 1996aArnett et al, , 1996bHuang et al, 1997;Hwang et al, 2000b;Moore et al, 1991). A posterior inclined condylar neck has been considered another contributing factor (Hwang et al, 2000a(Hwang et al, , 2000bHoppenreijs et al).…”

SUMMARY:The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3%) CR was observed , with a 97.6% (122) female. CR was related to 118 cases with mandibular deficiencies with high mandibular plane (advancement surgery). CR were present principally in bi maxillary surgery with a 103 cases (75.2%) and only two papers show any analysis to the relation with TMJ dysfunction. Current evidence in CR is poor but supports those female patients with mandibular deficiency and high mandibular plane angle submitted to bi maxillary surgery with change in occlusal plane (counterclockwise) are associated with condylar resorption after orthognathic surgery.

“…Previous studies have suggested that condylar resorption and atrophy are observed after surgical mandibular advancement. [1][2][3][4][5][6] Therefore, this type of intervention is sometimes unfavorable for patients with temporomandibular joint disorders (TMD).…”

Objective: To describe the orthodontic treatment of a nongrowing 30-year-old woman with asymmetric severe skeletal Class II malocclusions (asymmetric Angle Class II), large overjet (16 mm), large overbite (8 mm), two congenitally missing mandibular incisors (presenting a deciduous anterior tooth), and signs and symptoms of temporomandibular joint disorder (TMD). Materials and Methods: We used novel improved super-elastic Ni-Ti alloy wires (ISWs) combined with Ni-Ti alloy coil springs, power hooks, and a zygomatic implant as reinforced anchorage to provide a constant and continuous mild force to the dentition. Results: We successfully distalized maxillary molars, premolars, and retracted anterior teeth and corrected the asymmetric Angle Class II molar relationship using this system of zygomatic anchorage in conjunction with ISWs, Ni-Ti alloy open-coil springs, and crimpable power hook. The maxillary molars were distalized, and postero-occlusal relationships were improved to achieve Class I canine and molar relationships on both sides. Intrusion of the upper molars made the mandibular plane close. Ideal overbite and overjet relationships were established. Facial esthetics were improved with decreased upper and lower lip protrusion, and no symptoms of TMD were observed after treatment. Conclusion: The orthodontic treatment described here is a promising anchorage technique alternative to traditional techniques to improve severe skeletal Class II with TMD.
