I believe i had class 1 malocclusion on my mandibular. will rapid palatal expander help me?

Different problems: Class i refers to the front-to-back teeth and jaw relationship. If your lower jaw (mandible) is class i, it relates well to your upper jaw in the sagittal (front-to-back) plane. A rapid palatal expander is used to correct transverse (side-to-side) malrelationship by widening the upper jaw. Upper jaw widening in an adult requires the help of an oral surgeon and an orthodontist working together.

Malocculsion: No. This is true for several reasons, 2 of which are, 1. Arch expanders are not used to treat class 1 malocclusions, and 2. At your age the suture line in the palate are fully formed and closed. In order for an expander to work the palate must still be growing.

No: A class i malocclusion just refers to the relationship of molars. Someone stated that expanders are not used to correct class i malocclusions, this is untrue. If a patient has a palatal crossbite and is young enough, a rapid expansion of the palate is part of the treatment plan. It says you are 31 years old, as your growth is finished, rapid expansion (without surgery) is not at all possible.

Unlikely: As an rpe is typically only effective while you are still growing. That said, we have taken radical approaches in treating some patients with an rpe into their 20's and have in some cases, seem remarkable results. So, net-net, consult your orthodontist (or 2-- maybe one who like us is will to consider rpes past childhood) to determine the best course of action.

Nope: Rapid palatal expansion increase space for the upper teeth, not the lower (mandibular.) also, rapid palatal expansion is normally reserved for growing children.
