Rapid Palatal Expander

Mini-screw Assisted Rapid Palatal Expanders are a dental appliance used to correct issues related to a narrow upper jaw (maxilla). Its use does not require surgery and is a great option for adults who normally would need surgery to correct such issues. 

The results are always amazing.

How Does M.A.R.P.E. Work

The expander is attached using small mini screws which are placed using local anesthesia. 

The patient uses a special key to gradually activate the expander by turning the screw. This activates gentle forces that push against the palatal bones, gradually widening the upper jaw. 

As the expander is activated, the separation of the palatal bones stimulates the surrounding bone cells, triggering a process known as osteogenesis. This leads to new bone formation and proper expansion of the palate.

Once the desired expansion is achieved, the expansion appliance is typically kept in place for a certain period of time to allow for remodeling and stabilization of the newly expanded bone. Afterward, the miniscrews are removed

Dr. Estrada was so amazing! My son was nervous at first about getting his braces put on but Dr. Estrada made him feel very comfortable. I will definitely be bringing my daughter there when it's her turn.
