This paper reports on the bilateral distal movement of maxillary molars in the treatment of a dental Class II malocclusion with an appliance system that combines an active removable appliance with fixed molar bands and a cervical headgear. This combination of forces provides distal molar bodily movement where the molars have erupted or migrated mesially with a resultant loss of arch perimeter. The appliance system presented is a conservative, reliable technique that can be used to increase the maxillary arch length in growing as well as nongrowing patients.

D008437	Maxilla	One of a pair of irregularly shaped bones that form the upper jaw. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS.	Maxillae,Maxillary Bone,Bone, Maxillary,Bones, Maxillary,Maxillary Bones,Maxillas
D008963	Molar	The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)	Molars
