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. likely to see patients with implant-supported restorations or prostheses. << movement. /yb2 841.89 10 0 obj /Parent 3 0 R endobj Fourthly, the proprioceptors’ threshold and. This movement represents the mid-sagittal depression during the, clinical examination. During lateral excursion movement, the, non-working condyle moves downward, inward and forward. A synovial membrane lines the joint capsule. Even when the incisal guidance is flat, the forward, movement of the condyle on the articular eminence is at an angle that is, steeper than the posterior part of the occlusal plane, which will lead to, The curvature of the curve of Spee can be described according to the length of, the radius of the curve. >> area, which is important for dental professionals.
