Removable mechanical straightening device which mainly use Adams clasps, ball clasps and screws.
These devices include Expansion plates (for lateral expansion), Fantype (for fan-shaped expansion), Sagittal Appliance (for moving molars to the back), and other devices with various designs depending on the part of the tooth you want to move.
1. Mainly used for improving Class II malocclusion and distal movement of molars. Often used together with headgear.
2. As for the design of the device, the central incisors are attached to the labial bow and the resin pads are attached to the lateral incisors. This is to increase the force of the device and to prevent effects to the front teeth.
1. Used to move the first molar distally.
2. Mainly used to secure space for eruption of lateral teeth during the mixed dentition period. Can also be used with permanent dentition.
1. The plate is divided in the middle and used for bilateral crossbite and crowding improvement of the anterior teeth.
2. Used to secure space for teeth that have not erupted and are in the process of eruption.
1. Mainly used to expand the anterior dentition in the labial direction (the amount of screw expansion is about 3 to 4 mm on average; labial and lateral expansion can be performed)
2. Can be expanded laterally.
Used to expand the dental arch where lateral expansion of the maxillary anterior teeth is required more than for the posterior molars.
Used to expand the dental arch where lateral expansion of the mandibular anterior teeth is required more than for the posterior molars.
1. It is often used to improve Class II malocclusion.
2. When the opposite occlusion of the front teeth is extremely deep, an occlusal cover may be attached.
1. Mainly used to expand and move the first molar distally using a screw.
2. Highly effective when used around 6 to 7 years old before the second molar erupts.
Used to apply force to the maxillary area to promote lateral expansion and anterior-lower growth.
Used to apply force to the mandibular area to promote lateral expansion and anterior-lower growth.
1. Mainly used to improve malocclusion by performing lateral distal expansion of the molars and anterior expansion of the anterior teeth using a screw.
1. The structure is different from the screw used for normal lateral expansion. The exact direction and magnitude of the force can be limited.
2. When the function of the spring and the screw are combined, the force acts on one point. Especially used to rotate and expand teeth with limited space.
1. Used to close the space created between teeth.
Used to move the lingually inclined mandibular second molar to the buccal side.
1. Forward projecting tongue habit, abnormal swallowing habit, and other common habits such as thumb sucking.
Active Plate
1. Mainly used to improve overcapsular occlusion
2. Often used to treat overcapsular occlusion during mixed dentition
1. Used to improve malocclusion such as overcapsular occlusion and class II occlusion.
2. Device attached to the upper jaw with the part where the anterior teeth of the lower jaw come into contact has a structure that descends from the direction of the molars toward the anterior teeth.
Used to raise the position of the tongue.
Used to raise the position of the tongue.
Used to raise the position of the tongue.
