[{'content': 'Which of the following is not a factor in balanced occlusion? \nSelect and explain. \nA. More lingual the teeth are placed in relation to ridge, greater the balance, B. More buccal the teeth are placed in relation to ridge, poorer the balance, C. Wider the ridge and wider the teeth buccolingually, greater the balance, D. More centred is the force of occlusion anteroposteriorly, greater is stability of base', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Definition: The bilateral, simultaneous, anterior and posterior occlusal contact of teeth in centric and eccentric positions (GPT8).\nLever balance: This is the relation of the tooth to its base of support. It is important when a bolus of food is placed in between the teeth on one side and a space exists on the opposite side . It is enhanced by the following:\n\nPlacing the teeth such that resultant direction of force on the chewing side is on the crest or slightly lingual.\nPlacing the teeth close to the ridge.\nDenture base covering as wide an area as possible.\nReducing the buccolingual width of the teeth.\n\nKey Concept:\nWider the ridge and narrower the teeth buccolingually, greater will be the balance.\nRef: Textbook of prosthodontics V Rangarajan Ed. 2nd', 'role': 'assistant'}]
