“…The possible articular comphcations are joint instability and arthrosis (Scott, Bird & Wright, 1979). Katzberg et al (1982) showed that TM joints with reducible disc displacement (arthrographically demonstrated) translated twice the range of TM joints in patients with negative arthrographic findings. This was thought to be a manifestation of loosening of the eapsular and discal ligaments although there is no evidence that this was a predisposing or pre-existing factor.…”

According to linear interincisal measurements, women have a smaller maximum jaw opening than men. In this study the difference was 2.7%. In contrast, epidemiological surveys indicate that women have a greater mobility of joints and generally more joint laxity. Covariate analysis was used to test for the difference between sexes in mean maximum passive opening adjusted according to group mean differences in other parameters of body size. The net result was that the values became more equal between sexes. A second method, employing a geometric estimation for the angle of maximum jaw opening, showed that women had a 5.4% wider range of jaw opening than men (P less than 0.057). This method avoided the problem of considering relative body size and body factors which generally correlated poorly with maximum opening. It should be noted that an increased range of opening is a measure of hyperextensibility and does not necessarily imply laxity or instability.

“…However, examining generalized joint hypermobility patients, he did notice a trend of increased temporomandibular joint mobility. Katzberg et al (1982) found through arthrotomographic studies that patients who had temporomandibular joint disc displacement with reduction showed hypermobility of the condyle on the symptomatic side. Orthopaedic testing of joint mobility involves measurements of joint border positions (Carter & Wilkinson, 1964).…”

Peripheral joint mobility was assessed in a group of fifty-one dental students using a modification of the Carter and Wilkinson Index. Mandibular border positions were measured both actively and passively with the aid of a millimetre ruler. The purpose of the investigation was to study possible relationships between generalized joint (hyper-)mobility and (hyper-)mobility of the temporomandibular joints. Only a few weak correlations were found between the mandibular border position measurements (active and passive mouth opening, active and passive, left and right, laterotrusions and active protrusion) and the peripheral joint mobility measurements. Differences between the sexes were illustrated in peripheral joint mobility with females showing a greater joint mobility than males, especially when only the passively measured joints were considered. The mandibular border positions were significantly correlated with each other (P less than 0.05-P less than 0.001) for the males, but few and then only weak relationships between these measurements could be found for the females in this group. The concept of temporomandibular joint 'end-feel' in relation to joint mobility is discussed.

“…Ideas regarding the functional significance of mandibular AoR location have often been expressed as hypotheses regarding the functional significance of anteroposterior translation of the mandibular condyle in the TMJ, sometimes called 'sagittal sliding' (Hiiemaë and Kay, 1973;Smith, 1985;Wall, 1999;Hylander, 2006). This focus on condylar translation is attributable to the large magnitude of anteroposterior condylar translation in humans, its relevance for the etiology of disk derangements in human temporomandibular disorders (e.g., Farrar, 1978;Katzberg et al, 1982), and the fact that it is easier to measure condylar displacement than AoR lo cation. However, because anteroposterior condylar displacement during chewing is often − depending on species − accompanied by significant superorinferior displacement, hypotheses regarding condylar movements are better expressed as hypotheses regarding the location of AoR (Weijs et al, 1989;Gallo et al, 2000).…”
