“…The reconstructed model of the skull and the TMJ was oriented to reference planes, as reported in a previous study [16]. The sagittal plane perpendicular to the Frankfort horizontal plane divides the skull into symmetrical halves, thus all of the measurements to assess the mandibular displacement are taken in a section view according to this plane.…”

Background: Sleep-Related Breathing Disorders are characterized by repeated episodes of complete or partial obstruction of the upper airway during sleep. Mandibular advancement devices represent a non-invasive treatment in reducing the number of respiratory events and in decreasing symptoms. The advancement extent of these devices is responsible for the mandibular roto-translation and its effects on the temporomandibular joint. Methods: This study defined a systematic method to assess the mandible roto translation that is caused by MADs according to a scan-to-CAD approach. Starting from a closed mouth position and simulating the oral appliance at different settings it was possible to define a local reference system that is useful for the evaluation of the mandibular roto-translation. This latter was then applied to evaluate the movements of the condyle and the mandibular dental arch. Results: MAD1 resulted in a reduced mouth opening and protrusion, while MAD2 enabled a higher degree of motion of the mandible useful for patients who need an important protrusion. Conclusions: The two devices present different dynamics. Results that are achievable employing this method can be directly used by practitioners in comparing MADs, as well as by researchers in evaluating MADs effects.

“…The accuracy of condylar positioning after bilateral sagittal split osteotomy (BSSO) of the mandible infl uences the postoperative skeletal stability (1,2,3,4,5,6,7,8,9,10,11,12,13). The importance of positioning the condyle correctly in the fossa has been emphasized by an increased use of rigid or semi-rigid fi xation (9,10,11,12,13).…”

“…At surgery, when the condyles are seated properly in its preoperative relation to the glenoid fossa, any postoperative occlusal discrepancies should be corrected by the orthodontist (9,10,11). If the condyles are not seated properly, relapse may occur immediately after an intra-operative removal of the maxillomandibular fi xation (MMF), or later (7,12,13).…”

AIM: The purpose of this retrospective study was to perform an evaluation of postoperative positional changes of the condyle and mandibular function after bilateral sagittal split osteotomy (BSSO) with manual proximal segment positioning. PATIENTS: 45 patients were divided into the 2 groups-G1 (advancement-14 patients) and G2 (setback-31 patients). Rigid internal fi xation screws were utilized in all cases. Inclusion criteria were only BSSO, no TMJ symptoms preoperatively and age 18 or older. RESULTS: The differences between pre-and postoperative condyle position were evaluated using measurements taken from preoperative CT scans and compared to CT scans made a minimum of 6 months postoperatively. The positional changes in both the axial and sagittal planes were measured and compared. The recovery of mandibular function was evaluated by measuring maximal interincisal opening (MIO). The results revealed that condylar positional changes after BSSO in both groups were minimal and not signifi cantly different for all three dimensions measured. The recovery of mandibular function was faster in the group G2 than in the group G1. Mandibular function reached almost preoperative level in 6-12 months postoperatively in both groups. CONCLUSION: The results demonstrated that following BSSO, only insignifi cant condylar displacement and functional changes occurred within 6 to 12 months postoperatively (Tab. 4, Fig. 2, Ref. 47).

“…Dabei stellten diese und zwei weitere Studien, konform zu der vorliegenden Studie, bei stark asymmetrischen Patienten ein vergrößertes Condylus-Volumen auf der nicht-abweichenden Seite fest(Lin et al 2013;Yu et al 2018) Lin et al (2013). untersuchten zusätzlich die Größe der Condylus-Oberfläche bei stark asymmetrischen Patienten und stellte auch dabei einen signifikanten Anstieg auf der nichtabweichenden Seite fest.Einige Arbeitsgruppen ermittelten eine größere Seitendifferenz in der Condylus-Höhe bei stark asymmetrischen Patienten im Vergleich zu symmetrischen Patienten(Kamata et al 2017;Kim et al 2013;Lee et al 2017;You et al 2010). Dieser Unterschied war in der vorliegenden Studie ebenfalls anhand der 83 % Konfidenzintervalle zu beobachten.…”

“…Dieser Unterschied war in der vorliegenden Studie ebenfalls anhand der 83 % Konfidenzintervalle zu beobachten. Bei einem Seitenvergleich der Condylen zeigte sich in zahlreichen Studien weiterhin eine vergrößerte Condylus-Höhe auf der nicht-abweichenden Seite(Kamata et al 2017;Lee et al 2017;You et al 2010You et al , 2018Yu et al 2018). Oh et al (2018) untersuchten die Seitendifferenz der Condylus-Dicke in Abhängigkeit von dem Asymmetriegrad und konnten keine Unterschiede zwischen den Asymmetriegraden feststellen.…”
