The significance of occlusion in restorative dentistry Dent Clin North Am. The sagittal axis is an anteroposterior axis, which passes through, the working condyle during the lateral excursion of the mandible. and produces the synovial fluid that fills these two compartments. Interested in research on Restorative Dentistry? It is often necessary to allow, the posterior teeth to share the occlusal forces and to guide the mandible with, the anterior teeth. Furthermore, several factors that, influence mandibular movements during function should be considered, as they. >> /Kids [5 0 R 6 0 R 7 0 R 8 0 R 9 0 R 10 0 R 11 0 R 12 0 R 13 0 R] This movement takes place in the upper joint compartment. uuid:15b5e141-4b44-45fb-888c-ed68dd987021 However, as the number of patients who have dental implants is increasing, dental personnel are more.
