endstream The inward, movement of the non-working condyle is affected by two anatomical, factors: (1) the morphology of the medial wall of glenoid fossa and its, proximity to the medial pole of the non-working condyle; and, (2) the, inner horizontal part of the temporomandibular ligament that is attached, to the lateral pole of the working condyle. The joint is also composed of ligaments such as, the stylomandibular and temporomandibular ligament. It is restricted to a purely, recordable and reproducible in patients with no pain or derangement in the, when the MIP is not satisfactory, or when occlusal rehabilitation is needed, In order to record the CR clinically, several methods are used. /ModDate (D:20151021124039+01'00') stream /Parent 3 0 R >> /Contents 60 0 R location of the curve will serve two important purposes: arc of closure; therefore, maximum resistance to occlusal force is, achieved, as most of the periodontal ligaments are involved in dissipation, b.

Basic knowledge of occlusion is needed for a better dental treatment outcome. when measured between the upper and lower incisors. Canine teeth are suitable to guide the mandible during its excursive movement, for many reasons, as previously mentioned. Thirdly, the mandible is a type III lever (like a, nut cracker); hence, the occlusal force on these teeth will be less than that, imposed on the posterior teeth. On the other hand, the dynamic relationship of the, mandible to the maxilla is known as an articulation, and indicates the contact, relationship between the incising or masticating surfaces of the teeth during, To understand how the mandible moves, it is important to know the anatomy, of the TMJ. << A number of implant-supported treatment options have been used successfully to replace a single tooth and multiple teeth, as well as a completely edentulous jaw.
