Distalization of the posterior teeth can be achieved by using numerous fixed or removable appliances. All appliances can be customized for your individual patient needs.
The CD Distalizer (Mandibular) appliance is designed to uncrowd arches by distalizing Mandibular 6-year molars, principally for patients who are to be treated non-extraction, ages 10 years and 14 years. If the patient is older than this age range, it is nearly obligatory to extract the 12-year molars to achieve distalization of the 6-year molars greater than 1 to 2mm on each side of the arch. Immediately following the extractions of the 12-year molars, however, lower 6's can be distalized 3 to 5mm, depending on the maturity of the patient and the proximity of the lower third molars.
The maxillary CD Distalizer appliance is designed to uncrowd arches by distalizing maxillary 6-year molars, principally for patients who are to be treated non-extraction, ages 10 years and 14 years. If the patient is older than this age range, it is nearly obligatory to extract the 12-year molars to achieve distalization of the 6-year molars greater than 1 to 2mm on each side of the arch. Immediately following the extractions of the 12-year molars, however, the posterior buccal segments can be simultaneously distalized 3 to 8mm, depending on the maturity of the patient and the proximity of the third molars.
The design of the Pendulum appliance is credited to Dr. Jim Hilger. The appliance is designed to achieve molar rotation, molar distalization and when needed, lateral expansion simultaneously. The appliance is built on bands placed on the first permanent molars. On the lingual of the bands are special horizontal lingual tubes (Pendex tubes) into which are inserted the TMA springs. For anchorage two pair of rests are placed on the occlusal of the bicuspids and/or deciduous molars and are bonded in place. A large Nance button provides additional palatal anchorage. The TMA springs, which are imbedded in the Nance acrylic and inserted into lingual sheaths on the molar bands, provide the continuous light forces used for distalization. Rotation occurs as a function of the open helicals that are incorporated into the springs.
The design of the Snodgrass/T-Rex appliance is credited to Dr. David Snodgrass. The appliance is designed to accomplish both lateral expansion and molar distalization with one appliance. It is a hybrid of the Haas expander and the Hilger's Pendulum appliance. The appliance is built on bands placed on the first permanent molars. On the lingual of the bands are special horizontal lingual tubes (Pendex tubes) into which are inserted the TMA springs. For anchorage a pair of rests are placed on the occlusal of the first bicuspids and are bonded in place.
The upper and/or lower Fixed 3-Way Sagittal is built on to bands placed on the first permanent molars. The straight arms of the appliance allow the molars to distalize (they do not engage the lingual of the bicuspid teeth during distalization). Anchored into the anterior anchorage button of acrylic are rests for bonding in place on the first bicuspids. The rigidity of the appliance allows distalization without molar tipping, however, it is essential that the rests be bonded on the occlusal of the first bicuspids, and as desired to the anterior teeth. The bondable rests are needed for the correct anchorage for distalization, complete rigidity and they prevent the appliance from 'riding' up and/or off the anterior teeth.
The Sagittal appliance is a removable appliance comprised of expansion screws, clasping for retention and/or retraction, and acrylic. The upper Sagittal almost always has a posterior bite plane, the lower usually does not. It is an arch development appliance that can be used to accomplish various treatment goals.
These examples represent many of the most common appliances requested. However, we can custom design any appliance to your personal specifications with the quality and consistency you expect from your laboratory partner. For more information, Contact Us!
