Posterior disclusion is more easily obtained when the mandibular occlusal, plane is flat or convex. 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.

This is the bucco-lingual (mediolateral) curve that contacts the buccal and lingual, cusp tip on each side of the arch. 1 0 obj /Subtype /Image 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. These include, bimanual mandibular manipulation with or without a jig, chin point guidance, with or without a jig, and Gothic arch tracing. These three factors, influence the mandibular movements, as they dictate the direction, duration and, timing of mandibular movements and consequently affect occlusal morphology. %PDF-1.4 /xb1 0 Nevertheless, dental implants may fail as a result of mechanical complications, such as screw loosening or due to biological causes like peri-implant diseases. /yb2 841.89 /CropBox [0 0 595.276 841.89] separation (disclusion) between the mandibular and maxillary posterior teeth is, dependent on the length of the radius of the curve of Spee such as when the, radius is short, the separation is greater and the posterior cuspal angles are, The curve of Spee may be pathologically altered by rotation, tipping and over-, eruption of teeth.

This can be achieved by, customising the incisal guidance and copying the palatal surface of these teeth, in an impression from which the technician can transfer the palatal surface of, the teeth to the restorations, or by using a custom-made incisal guidance, This is defined as the average plane established by the incisal and occlusal.
