Flush Terminal Plane.. alignment of the distal surfaces of the upper and lower second primary molars when the jaws are closed in occlusion

Flush Terminal Plane:

Since we're focusing on dentistry, let's dive deeper into flush terminal plane in this context!

Flush terminal plane in dentistry:

- Definition:

This term refers to the alignment of the distal surfaces of the upper and lower second primary molars when the jaws are closed in occlusion. In simpler terms, the chewing surfaces of both molars align perfectly without any overlap or gap.

- Significance:

A flush terminal plane is considered the ideal and most common occlusal relationship for primary molars. It ensures proper chewing function, promotes healthy tooth development, and prevents potential malocclusions later in life.

- Alternative relationships:

Deviations from flush terminal plane are also possible:

• Mesial step: The lower second molar is slightly more distal (toward the back) than the upper second molar.
• Distal step: The lower second molar is slightly more mesial (toward the front) than the upper second molar.

- Assessment:

Dentists evaluate the terminal plane relationship during routine dental checkups to monitor tooth development and identify any potential issues.

- Importance:

Maintaining a flush terminal plane or addressing any deviations early on can help prevent future orthodontic problems, like overbite or underbite.

Here are some additional points to consider:

• The flush terminal plane relationship applies specifically to the second primary molars, not all primary teeth.
• The development of permanent molars can sometimes alter the terminal plane relationship, making early monitoring important.
• If you have any concerns about your child's tooth development or occlusal relationships, consult with a pediatric dentist for proper evaluation and guidance.
