Definitions
- the present invention relates to apparatus and methods for installation of a dental bracket for the slow release of a medicament, particularly but not exclusively fluoride for the improved treatment and/or prevention of dental caries.
- Dental caries consist of demineralization of a tooth caused by bacteria. In the early stages of caries a white spot develops on the tooth and if the disease is not halted and reversed, the enamel surface breaks down to form a lesion. This can then lead to decay and eventually, a fractured or pitted tooth. It is well known that development of dental caries may be reduced by means of various factors, such as diet and oral hygiene measures, anti-microbial treatments and the provision of fluoride to the teeth.
- the present invention is directed to a placement device for installing a dental bracket designed to receive a medicament-releasing pellet onto a tooth of a patient.

Description
- This application is a continuation-in-part of co-pending U.S. application Ser. No. 10/793,145, filed Mar. 4, 2004. The foregoing U.S. application is incorporated herein by reference.
- 1. The Field of the Invention
- The present invention relates to apparatus and methods for installation of a dental bracket for the slow release of a medicament, particularly but not exclusively fluoride for the improved treatment and/or prevention of dental caries.
- 2. The Relevant Technology
- Dental caries consist of demineralization of a tooth caused by bacteria. In the early stages of caries a white spot develops on the tooth and if the disease is not halted and reversed, the enamel surface breaks down to form a lesion. This can then lead to decay and eventually, a fractured or pitted tooth. It is well known that development of dental caries may be reduced by means of various factors, such as diet and oral hygiene measures, anti-microbial treatments and the provision of fluoride to the teeth.
- Current methods for administering fluoride include the fluoridation of drinking water, the ingestion of fluoride tablets, the incorporation of fluoride into mouth washes, dentifrices and foods, the topical application of fluoride solutions, gels and varnishes, and recently, the incorporation of fluoride in dental materials and special devices. These have a variable effect on caries which is unpredictable on an individual basis and is dependent on patient compliance in following the prescribed regimen.
- Evidence supports the concept of frequent applications of relatively low concentrations of fluoride ions for the elimination of caries. A sustained and controlled release delivery system could help to achieve this goal. At least three general approaches have been reported for the application of sustained and controlled slow releasing systems: (1) a sustained release ingested tablet or capsule (Masuhara et al. 1985); (2) incorporation of fluoride into dental cements (McClean & Wilson); and (3) an intra-oral device attached to the teeth (Minth et al. 1983). However, each of these existing technologies has been difficult to use, unpredictable, susceptible to damage, an irritant to surrounding tissue, or unacceptable to the patient.
- The present invention is directed to a placement device for installing a dental bracket designed to receive a medicament-releasing pellet onto a tooth of a patient.
- The placement device includes a body sized and configured to be at least partially inserted into a person's mouth, and a protrusion disposed on the body. The protrusion is sized and configured to releasably attach to a socket of a dental bracket.
- According to one embodiment, the body comprises an elongate handle, and the protrusion is located near an end of the handle. According to one embodiment, the protrusion is male so as to mate within a correspondingly-sized and shaped female socket of a dental bracket. The male protrusion may have any of various shapes corresponding to the shape of the medicament-releasing pellet to be received by the dental bracket socket. For example, the male protrusion may be spherical, circular, ellipsoidal, loaf-shaped, bar-shaped, or any other shape.
- According to another embodiment, the protrusion includes a female cavity capable of receiving the socket of a dental bracket. The socket of the dental bracket may be one of various shapes configured to receive a medicament-releasing pellet that may be spherical, circular, ellipsoidal, loaf-shaped, bar-shaped, or any other shape. The female cavity of the protrusion has a shape and size configured to receive the correspondingly shaped socket.
- The socket of a dental bracket may be either flexible or rigid. It may be preferable to use a placement device having a male protrusion with a dental bracket having a flexible socket and to use a placement device having a protrusion with a female cavity with a rigid socket.
- The placement device may be formed of any biocompatible material, such as a biocompatible metal (e.g., stainless steel or nickel-titanium) or plastic. According to one embodiment, at least a portion of the placement device may be formed of a transparent plastic material.
- According to one embodiment, the placement device may be attachable to a dental curing light. Such an embodiment may provide additional convenience and ease of use when using the placement device to place a dental bracket and bonding the bracket to a patient's tooth with a light curable adhesive resin.
- These and other benefits, advantages and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
- In order that the manner in which the above recited and other benefits, advantages and features of the invention are obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Althoughprotrusion 404 is illustrated as male, a protrusion including a female cavity could alternatively be used. - IV. Exemplary Method of Use
- The medicament release kit may be attached to a patient's tooth, as illustrated in
FIGS. 5A and 5B .FIGS. 5A and 5B illustrate attachment of thekit 100 illustrated inFIG. 1 using the placement device illustrated inFIG. 2A , although other embodiments may similarly be used. The dental practitioner attaches theprotrusion 204 of the placement device 200 (as seen inFIG. 2B ) to thesocket 108 of the dental bracket so as to be coupled with to theplacement device 200. The dental practitioner then positions the dental bracket onto the surface oftooth 512. Thebase 106 of the dental bracket is bonded to thetooth 512. This may be done with any suitable adhesive, e.g., a chemical or light curable adhesive resin.FIG. 5A illustrates use of adental curing light 513 to cure a light curable adhesive resin, bonding thedental bracket 104 to thetooth 512. - In one embodiment, the bonding side of the base 106 may have the first part of a two-part chemical cure adhesive resin pre-applied. In another embodiment, the bonding side may have a light activated resin pre-applied. Pre-applying either adhesive aids the dental practitioner in ease of use and placement. With the adhesive in place (whether pre-applied or applied by the dental practitioner), the dental bracket is positioned onto the tooth. The
base 106 provides sufficient surface area for bonding to thetooth 512. According to one embodiment, thebase 106 is sufficiently curved and flexible so as to tightly fit the contour of the patient's tooth. Once the dental bracket is bonded to the tooth, the medicament-releasingpellet 102 may be installed in thesocket 108. The medicament-releasingpellet 102 may be held within thesocket 108 by a friction fit, or by placing a bead ofsilicone resin 514 between thesocket 108 and thepellet 102. As illustrated inFIG. 5B , it is preferable to bond the device to the patient's first upper molar, although other positions could be used. In addition, it may sometimes be desirable to install more than one device within the patient's mouth, for example, one device may be attached to each of the upper and lower first molars. - The medicament release kit provides a bracket which may be installed by a dental practitioner, and which is intended to remain installed in the patient's mouth over a long period of time (e.g., up to 20 years). The medicament-releasing pellet is intended to provide slow release of a medicament (e.g., fluoride) over a period between about 6 months and about 2 years, after which time the pellet may be removed and replaced, either at home or at a dentist's office.
- It will also be appreciated that the present claimed invention may be embodied in other specific forms without departing from its spirit or essential characteristics.
