Pt. have upper denture everything is normal (speaking , eating...) but the upper lip showing short:

OR

Old patient with a new denture he came and said no problem in chewing or speaking or anything…but you noticed that upper lip is falling down and the vermilion border was affected:

• A. Vit. B deficiency.
• B. low vertical dimension.

SHORT VERTICAL = MORE SPACE = MORE LIP

The most likely cause of the patient's short upper lip with a new denture is B. low vertical dimension.

Here's why:

• Vertical dimension refers to the distance between the upper and lower jaws when the teeth are in occlusion (biting together).
• A low vertical dimension means that the jaws are closer together than they should be, which can cause the upper lip to appear short and fall down.
• This can also affect the vermilion border, the red part of the lip, making it appear less defined or even inverted.

While vitamin B deficiency can cause various oral health problems, including changes in lip appearance, it's less likely to be the primary cause in this case, especially given the patient's normal function with the denture.

Therefore, low vertical dimension is the more probable explanation for the short upper lip in a patient with a new denture.
