What steps are involved in arranging denture teeth for balanced occlusion?

• A. Establish vertical dimension, set incisors for aesthetics and phonetics, arrange posterior teeth to achieve bilateral balance or group function, verify occlusal contacts.
• B. Arrange only anterior teeth.
• C. Ignore vertical dimension.
• D. Place teeth randomly.

Answer: (C)

Arranging denture teeth for balanced occlusion starts with establishing the vertical dimension of occlusion. This sets how tall the denture will be and influences aesthetics, phonetics, and how the jaw moves against the teeth. If the vertical dimension isn’t correct, the denture won’t function or look right, and balance will be impossible to achieve. Next, position the anterior teeth for aesthetics and phonetics. The incisal edges and the way the front teeth meet the lips and tongue affect appearance and speech, so placing them with the proper height, angulation, and alignment is essential before balancing the bite. Then arrange the posterior teeth to create bilateral balance or group function. This means shaping the occlusal surfaces and cusp heights so that, in centric and during lateral or protrusive movements, there are contacts on both sides (or a deliberate group of teeth) to stabilize the denture and prevent tipping during chewing. Finally, verify the occlusal contacts throughout movements and adjust as needed. Check centric stops, lateral excursions, and protrusion to ensure even contacts and avoid interferences that could destabilize the denture. Placing teeth without a correct vertical dimension or without considering aesthetics, phonetics, and posterior balance makes balanced occlusion unattainable, which is why the described sequence is essential.
