To record the occlusal plane in order to:
- A. To determine the amount of space between the mandible and the maxilla which will be occupied by an artificial teeth.
- B. To determine vertical and horizontal level of the teeth.
- C. A and B.
- D. None.
The correct answer is C. A and B.
The occlusal plane is an imaginary line that connects the biting edges of the upper and lower front teeth, and it slopes slightly downward towards the back. Recording the occlusal plane is crucial for several reasons, including:
A. Determining the space between the mandible and the maxilla for artificial teeth:
When creating dentures or other prostheses, dentists need to know how much space is available between the upper and lower jaws to ensure proper fit and function. The occlusal plane helps determine the vertical dimension of this space, allowing for accurate design of the restoration.
B. Determining the vertical and horizontal level of the teeth:
The occlusal plane serves as a reference point for assessing the vertical and horizontal positioning of individual teeth. This information is essential for diagnosing and treating various dental conditions like malocclusions and bite problems.
Therefore, recording the occlusal plane is valuable for both determining space for dentures and assessing the levels of teeth, making option C the most accurate answer.
Other Options:
Here's a breakdown of why the other options are incorrect:
D. None:
Recording the occlusal plane is a crucial step in various dental procedures, so this option is incorrect.
A only:
While space for artificial teeth is important, the occlusal plane also aids in assessing tooth levels, making option A incomplete.
B only:
While tooth level assessment is crucial, space for prosthetics is also a key consideration, making option B incomplete.
