What is an anterior repositioning splint?

My dentist told me I needed an anterior repositioning splint. I started to ask, but my dentist had to go. He said he’d get back with me, but he hasn’t returned my calls. I don’t want to get a procedure done without knowing what it is.

I’m sorry for how you’re being treated by your dentist. It is unacceptable for a dentist to expect a patient to just compliantly do whatever he says without explaining everything about the procedure. In fact, I’d go so far as to say it was unethical.

An anterior repositioning splint is generally made out of acrylic. They are commonly used to to reposition or the temporomandibular joint, which is the hinge part in the jaw from which we derive the name TMJ.

The splint will allow your lower jaw and temporomandibular joints to move into a forward position to reduce any clicks or lock jaw that may happen when you open and close your mouth.

Usually these splints are worn full time for three to four months. They are a few millimeters thick and if worn on the top arch can affect ones speech.
