study
The following study provided a form of tongue guard meant for treating maxillary forward and down growth deficency. However, Since the tongue is placed behind the cribs at rest, equilibrium between tongue and lip pressures may change, resulting in lingual tipping and sometimes anterior crowding of mandibular incisors. This phenomenon can be prevented by inserting a lingual arch in patients with complete eruption of lower incisors to maintain lower arch periphery. Other considerations include sufficient height to prevent forward positioning of the tongue beneath the cribs that can exert forces to mandibular anterior teeth. If the tongue guard contacts the mouth floor, the loops be bent inwards using pliers to prevent soft tissue irritation. Place the tongue behind the cribs when swallowing, speaking, and at rest to transfer tongue pressure to the maxillary complex. "In the present study, forward and downward movement of maxilla was observed, evidenced by increased SNA and A-NPog." Minimal downward and backward rotation of the mandible explained by vertical growth of the face.
"Tongue guard appliance is effective for correction of mild to moderate skeletal Class III malocclusions, resulting in forward movement of maxillary complex."
