Rapid palatal expansion (RPE) with conventional tooth borne versus tooth and bone-borne versus pure bone-borne devices, what is the best option?

Rapid palatal expansion (RPE) is utilized for treatment of a skeletal crossbite and /or in combination with a facemask for protraction of the maxilla. Conventional tooth-borne appliances rely on an almost complete dentition to transmit the expansion forces to the bony structures of the maxilla and the mid-face. In most cases, tooth borne appliances produce side effects such as buccal tipping of the lateral tooth segments imposing a risk of bony and gingival fenestrations. To overcome these drawbacks, pure bone-borne (palatal distractors) or half bone-borne RPEappliances (Hybridhyrax) were developed.

Many clinical cases as well as advantages and drawbacks of the different treatment opportunities are discussed, respectively.
