D-BAR CLASS II CORRECTION APPLIANCE KIT
WHEN TO USE D-bar is a device that offers a quick and effective solution for Class II malocclusions, either in patients with primary, permanent, or mixed dentition. This is preferably used at the beginning of treatment for distalization of molars and premolars.
D-bar can be used alone or with other devices such as aligners or fixed orthodontic appliances.
D-bar also helps in Class III cases by placing it on the lower arch.
FEATURES
D-bar is universal and consists of two components, a molar socket and a bar, which are delivered unassembled.
It is possible to easily replace only the bar or change its size during therapy if clinical conditions require. This feature makes D-bar flexible, reducing and simplifying the clinic’s inventory.
D-bar can also be integrated into the digital workflow and placed by indirect bonding; in fact, the use of two separate components makes it possible to integrate the device into templates or transfer jigs.
D-bar is entirely made by MIM technology in 17-4 stainless steel; the retentive base is made with a high-frequency laser system for excellent resistance to detachment. Any orthodontic adhesive can be used.
D-bar is available in one millimeter increments in twelve sizes, from size 16 to 27. Measurement identification is easy and fast, thanks to laser marking.
ADVANTAGES
Control of the molar-canine segment. The connection system has been designed with tight tolerances to increase treatment effectiveness by minimizing undesired inter-arches or cuspids movements.
Effectiveness. The position of the hook on the canine’s mesial side increases the appliance’s effectiveness by increasing horizontal forces compared to vertical extrusion.
Easy positioning. The mesiodistal and occlusal-gingival positioning lines facilitate the positioning of the socket on the tooth.
Reduced treatment time. The use of a D-bar improves the molar relationship, which speeds up the orthodontic treatment.
Comfort. Its smooth and low-profile design improves patient comfort and compliance during treatment.
HOW TO USE
After selecting the most appropriate D-bar size, bond the molar socket to the upper molar (or premolar, if required).
Insert the bar into the molar socket until the round end completely disappears, then continue to bond the other end to the canine (or premolar, if required). On the lower molar or bicuspid, bond an auxilliary appliance (tube or lingual button) and connect it to the hook of the bar with an intraoral elastic.
After solving the Class II, the D-bar can be removed.
It is always recommended to consult the instructions supplied.
