Abstract

A disposable, double-ended, non-metallic dental sealer for personal use made of plastic, resin or another resilient material, comprising a handle and two dental picks projecting axially from either end of the handle. The dental pick includes a stem and an intermediate section projecting from the stem, terminating in a tapered tip. The tips are resilient and softer than conventional metallic tips used by professional dental practitioners. The two tips on the either ends of the handle are equally and oppositely angled with respect tσthe intermediate sections connected thereto. Due to this angled construction, one of the tips is used for cleaning on the right side of inter-proximal spaces between adjacent teeth while the other tip on the opposite end of the handle is used for cleaning on the left side of inter-proximal spaces.

BACKGROUND

[0001] The present invention relates in general to dental hygiene devices, more particularly to a dental sealer, and more particularly to a non-metallic double- ended dental sealer that is disposable and safe enough for personal use. [0002] Dentists frequently use sealers in the process of removing plaque and other debris from teeth and in particular, the inter-proximal spaces between teeth. Sealers used in professional dentistry are metallic, and can damage the tooth surface. For this reason, sealers currently known in the art are only used by dental

CONFIDENTIAL ATTORNEY WORK PRODUCT ATTORNEY CLIENT PRIVILEGE professionals.

[0003] Several dental hygiene devices have been developed in art. For example, U.S. Pat. No. 6,247,477 to Wagner discloses a multifunction dental appliance, which includes a cylindrical barrel and a cylindrical carrier plug having a dedicated dental implement, such as a pick or scaler, fitted at one end of the barrel. The other end of the carrier includes a universal affixment post for a further dental implement which is selected from a variety of attachments such as an interdental stimulator, a toothbrush head, a burnishing head, an abrasive stain removing head, a prophy cup, and an interproximal brush. Optionally, both ends of the barrel are open and a carrier is inserted in each end such that two dental implements are available at the same time, without removal of the carriers or attachments. [0004] U.S. Pat. No. 4,326,548 to Wagner discloses a dental tool for personal oral hygiene, which includes a pen barrel shaped holder carrying a curved metal pick. The pick includes an arcuate zone ending at a tapered tip. Opposite the tip, the pick includes a stem which is seated in the holder. The pick is formed of a stainless resilient metal alloy having a diameter in the order of one millimeter. The arcuate zone is employed to dislodge food or debris from pockets or interproximal spaces at both the mesial and distal areas of the oral cavity with the tip functioning as a probe. The convex surface of the arcuate zone is employed as a burnishing implement for the removal of soft plaque. However, the above two Wagner's devices are different from the present invention, which concentrates on providing safety and ease for personal usage by suitably designing and employing resilient materials such as plastic for the tips of the dental sealer.

CONFIDENTIAL ATTORNEY WORK PRODUCT ATTORNEY CLIENT PRIVILEGE [0005] U.S. Pub. No.20050244788 to Feine discloses a method for supplying dental practitioners with single-use plastic tips for use with an insert for a hand piece in an ultrasonic dental sealer. The single-use tip is employed for maintenance and preventive care for patients with titanium and other dental implants. The tip is packaged individually and sterilized by gas or irradiation, only to be removed after purchase, such as by the dental professional just before use on a patient. Upon completion of the patient care, the tips are preferably discarded. Although this system employs plastic tips, they are to be used by a dental practitioner as opposed to the present invention, which is much softer and therefore safer for personal use. [0006] Since dental sealers with metallic tips are not safe for personal use due to the risk of damaging the teeth, it is an object of the present invention to provide a non-metallic double-ended dental sealer specially designed for safe personal use by employing soft and resilient tips.

[0007] A further object is to provide a double-ended dental sealer that is cheaper to produce.

[0008] A further object is to provide a double-ended dental sealer that is easy to use and efficient in cleaning inter-proximal spaces between the teeth. [0009] Finally, it is an object of the present invention to provide a double- ended dental sealer that is more convenient to use than a dental floss in removing debris from teeth. These and other objects of the present invention will become better understood with reference to the appended Summary, Description, and Claims.

CONFIDENTIAL ATTORNEY WORK PRODUCT ATTORNEY CLIENT PRIVILEGE SUMMARY

[0010] The present invention relates in general to dental hygiene devices, and more particularly to a disposable, double-ended, non-metallic dental sealer that is specially designed for personal use. The dental sealer is made of plastic and comprises a handle and two dental picks projecting axially from either end of the handle. The dental picks comprise a stem connected to the end of the handle and an intermediate section terminating in a tip. The tips are resilient, softer and therefore safer to use, in contrast to the tips of conventional metallic sealers used by dental practitioners.

[0011] The two tips on either ends of the handle are equally and oppositely angled with respect to the intermediate sections to which they are connected. Therefore, one of the angled tips will allow for use on the right side of inter-proximal spaces between adjacent teeth, while the other oppositely angled tip on the opposite end of the handle will allow for use on the left side of inter-proximal spaces. The intermediate section can comprise different designs such as an arced structure, a combination of substantially linear segments, or other structures typical of metallic dental sealers known in the art.

DETAILED DESCRIPTION

[0015] Referring to the drawings, the preferred embodiment of a double- ended dental sealer is illustrated and generally indicated as 10 in FIGS. 1 through 5. The dental sealer 10 is especially designed for safe personal use. The dental sealer 10 is made is made of a non-metallic material such as plastic, and is cheaper to produce compared to conventional stainless steel or metallic dental sealers. [0016] Referring to FIGS. 1 through 4, the dental sealer 10 of the present

5

CONFIDENTIAL ATTORNEY WORK PRODUCT ATTORNEY CLIENT PRIVILEGE invention comprises a handle 11 and two dental picks 12 projecting axially from either end of the handle 11. The dental picks 12 include a stem 13 connected to the end of the handle 11 , a first substantially linear segment 14 projecting at an angle from the stem, a second substantially linear segment 15 projecting at an angle from the first linear segment 14 and a tip 16 projecting at an angle from the second linear segment 15. Being made of plastic resin, or another similar non-metallic material, the tips 16 are resilient, softer, and safer than conventional metallic picks used by dental practitioners, making the dental sealer 10 suitable for personal use. [0017] The two tips, first 16A and second 16B, on either end of the handle are in different planes, as shown in FIG. 4. The first tip 16A and the second tip 16B are equally and oppositely angled with respect to the second linear segments 15. The first tip 16A on one end of the handle is angled for use on the right side of the interproximal spaces between adjacent teeth, while the second tip 16B is angled for use on the left side of inter-proximal spaces between adjacent teeth. This design of the tips makes the dental sealer 10 more convenient and efficient for cleaning interproximal spaces.

[0018] Referring to FIGS. 5 through 8, an alternate embodiment of the dental scaler 17 is illustrated. In this embodiment, the sealer 17 is also double-ended and made of a non-metallic material such as plastic or resin. The dental pick 18 includes a stem 13, an arced zone 19 projecting from the stem 13, and a tip 20 projecting at an angle from the arced zone 19. The tips 20 are resilient, softer, and safer than conventional metallic picks. Similar to the previous embodiment 10, the two tips, first 2OA and second 2OB, on either end of the handle 11 are in different planes and

6

CONFIDENTIAL ATTORNEY WORK PRODUCT ATTORNEY CLIENT PRIVILEGE are equally and oppositely angled with respect to the arced zones 19 connected thereto, as seen in FIG. 8. The first and second tips are angled to allow for use on the right and left side of the inter-proximal spaces between teeth, respectively. [0019] FIGS. 9 through 12 show an alternate embodiment of the invention.

The criterion for this and all other alternate embodiments is that the two tips on either end of the handle are resilient, softer, and equally and oppositely angled to allow for use on both the right and left side of inter-proximal spaces between teeth. The two linear segments and the arced zone may be replaced in alternate embodiments with any other structure that is typically used in metallic dental sealers. The plastic dental sealers of the present invention are disposable unlike metallic sealers, which are relatively expensive and must be sterilized prior to re-use. [0020] All features disclosed in this specification, including any accompanying claims, abstract, and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

[0021] Any element in a claim that does not explicitly state "means for" performing a specified function, or "step for" performing a specific function, is not to be interpreted as a "means" or "step" clause as specified in 35 U.S.C. § 112, paragraph 6. In particular, the use of "step of in the claims herein is not intended to invoke the provisions of 35 U.S.C. § 112, paragraph 6.

[0022] Although preferred embodiments of the present invention have been shown and described, various modifications and substitutions may be made thereto
