<p><strong>Introduction:</strong> Patients with Syndrome type II division 2 malocclusions, besides presenting a clinically established relationship between molars and canines in a distal occlusion, show a retro-inclination of the upper front teeth with pro-inclination of the lateral incisors and a deep overbite, which can result in a risk factor of temporomandibular dysfunction<strong>. </strong></p><p><strong>Objective:</strong> To identify the relationship between Syndrome type II division 2 malocclusions<strong> </strong>and the temporomandibular dysfunction.</p><p><strong>Material and Methods: </strong>A bibliographic review was carried out through a search of databases such as MEDLINE, PubMed, Hinari, and Scholar Google. A total of 17 articles were used.</p><p><strong>Development: </strong>Because of the clinical characteristics of the occlusion in the patients with this syndrome, the range of jaw movement is limited, producing a traumatic effect that is related with a position of the condyles displaced backward and with glenoid fossa intrusion. This more distal displacement produces the pressure of the richly innervated retrodiscal tissue, which could be the cause of inflammation of the surrounding tissues and the affectation of the joint function due to an elongation of the discal ligaments or a thinning of the disc affecting the disc-condyle complex.</p><p><strong>Conclusions: </strong>The studies conducted demonstrate the relationship between the Syndrome type II division 2 and the temporomandibular joint dysfunction, given the clinical characteristics that are present in this syndrome, which affect the functioning of the temporomandibular joint, and produce its dysfunction when exceeding the adaptive capacities of the patient.<strong></strong></p><p><strong>Keywords:</strong> Syndrome type II division 2 malocclusions, temporomandibular dysfunction, deep overbite, malocclusion.</p>
