ABSTRACT:
Apparatus for holding and installing a plurality of orthodontic brackets on a patient's teeth includes an opaque housing having a plurality of spaced slots each adapted to receive a pliers, or tweezers, of the "reverse locking" type, where each pliers engages and supports a respective orthodontic bracket. Attached to the user engaging end, or handle, of each pliers is an opaque silicone cap which facilities gripping the pliers, maintains the pliers securely in position in the housing, and forms an airtight seal about each slot in the housing. Applied to each orthodontic bracket is a light-curable composite bonding material which is maintained in position within a respective slot in spaced relation from the housing. The bracket installer grasps a silicone cap in removing the pliers and orthodontic bracket combination from the housing and affixes the bracket to an intended tooth by means of the bonding material. With the housing providing a sealed enclosure and each slot sealed in an airtight manner by a respective pliers cap, an inert gas may be injected into the housing to preserve the bonding material over an extended storage period. The housing includes connected upper and lower members which can be separated to allow for recovery of dropped brackets, cleaning of the housing, and sterilization. The orthodontic bracket holding and placement apparatus simplifies and substantially reduces the number of steps involved in installing orthodontic brackets as well as the time required.
