[{'content': 'Which of the following factors of balanced occlusion is given by the patient? \nSelect and explain. \nA. Condylar guidance, B. Incisal guidance, C. Inclination of the cusps, D. Orientation of the occlusal plane', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Condylar guidance\nDefinition: The mechanical form located in the upper posterior region of an articulator that controls movement of its mobile member (GPT8).\nCondylar guide inclination: The angle formed by the inclination of a condylar guide control surface of an articulator and a specified reference plane (GPT8).\n\nThis is the mandibular guidance generated by the condyles traversing the contours of the glenoid fossa.\nIt is duplicated in the articulator. The extent of duplication depends on the articulator’s capability, whether it is semi-adjustable or fully adjustable.\nProtrusive condylar guidance is obtained using protrusive records,while the lateral condylar guidance is obtained using Hanau’s formula or lateral records\xa0\nIt is designated as an inclination or angle – condylar guidance angle or inclination – and is expressed in degrees.\nThis is the only factor that is obtained from the patient and is not under the dentist’s control.\nA shallow condylar guidance will cause less posterior tooth separation in protrusion and requires teeth with shorter cusps and flatter fossa to achieve balanced occlusion, than a steep guidance.\n\nKey Concept:\nOut of the ﬁve factors of balanced occlusion, only condylar guidance is recorded from the patient by\xa0the means of protrusive records.', 'role': 'assistant'}]
