The present invention relates to dental equipment. More particularly, this invention relates to a method and apparatus for removing unwanted material between teeth.
After filling a tooth with composite, the dentist uses tools to shape and form the filling or amalgam material to provide the desired shape and smoothness. However, when filling a tooth which is in contact with another tooth, such as a distal occlusal (DO) or a mesial occlusal (MO), frequently a portion of filling material overhangs interproximately or between the teeth. Typically, the dentist uses a sanding strip to remove the overhanging material. The sanding strip is an elongated strip of material having an abrasive surface portion which is inserted in the gap between the teeth and then moved back and forth in a sawing motion against the unwanted material to remove the unwanted material. However, it is often difficult to get the sanding strip into the space between the teeth. Accordingly, it is desirable to provide an improved sanding strip which is easily used by the dentist.
An improved dental sanding strip for removing material between the teeth is provided. The dental sanding strip includes a lead portion extending from one end of the dental sanding strip to facilitate the insertion of the strip into the space between the teeth. The dental sanding strip is an elongated strip of film having a first end and a second end. The first end having an abrasive portion and the second end having a holding portion. The lead portion extends from the first end, the area having the abrasive portion. The lead portion is affixed to the First end in a suitable manner such as with adhesive or by heat welding. The first end of the dental sanding strip is tapered toward the lead portion providing a gradual transition from the lead portion to the full width dental sanding strip. The lead portion of the dental sanding strip is inserted between the teeth by first inserting a free end of the lead portion into the space between the teeth. The dentist then grasps the lead portion and pulls the lead portion thereby permitting the abrasive portion of the dental sanding strip to contact the area on the tooth to be removed. The dentist may then manipulate the dental sanding strip to remove any unwanted material between the teeth. The dentist uses a back-and-forth motion, or a circular motion, to remove the unwanted material between the teeth.
The present invention provides a dental sanding strip including a lead portion extending from one end of the dental sanding strip to facilitate the insertion of the dental sanding strip into the space between the teeth. The dental sanding strip includes an abrasive portion, a gripping portion, and the lead portion.
A dental sanding strip 10 is commonly used by dentists to remove overhanging material, or any unwanted material, on a tooth. A dental sanding strip 10 includes a first end 18 and a second end 16. The dental sanding strip 10 further includes an abrasive portion 14 and a gripping portion 12. A back surface 15 is smooth so as to not disrupt adjacent teeth. The first end 18 is inserted between teeth to remove any unwanted material. However, it is often difficult to insert the dental sanding strip 10 into the space between the teeth.
The present invention provides a dental sanding strip 20 having a first end 32 and a second end 28, as shown by
The dental sanding strip 20 is an elongated strip of film such as Mylar. The strip is approximately 7 inches long and has a width of between 0.125 inches and 0.25 inches. The abrasive portion 26 is approximately 4 inches long.
The lead portion 30 extends from the first end 32. The lead portion 30 is an elongated filament extending from the first end 32. The lead portion 30 is an elongated flexible member. The lead portion 30 is also described as an elongated, flexible filament with high resilience and flexibility allowing for easy manipulation and maneuverability between the teeth 42. The lead portion 30 is formed of a suitable material which retains its shape but has some flexibility. An acceptable material is a plastic or nylon filament, or any resilient, flexible material. The lead portion 30 may be of a material similar to a heavy weight floss, or heavy weight fishing line. The lead portion 30 is approximately 1 inch long. The lead portion has a circular cross section and may optionally have a rectangular, square or triangular cross section. The lead portion 30 extends from the first end 32, and may be affixed to the dental sanding strip 20 at the abrasive portion 26 or at the smooth side 24. The lead portion 30 is adapted to facilitate insertion of the dental sanding strip 20, thereby aiding the dentist in removing any unwanted material.
The dental sanding strip 20 is intended for use in a human mouth 40. The human mouth 40 includes teeth 42 and a gum line 44. The dental sanding strip 20 is required when a tooth 42 includes an overhang 46, or other unwanted material such as plaque. The lead portion 30 of the dental sanding strip 20 is inserted between the teeth 42. The lead portion 30 which extends from the first end 32 of the dental sanding strip 20 facilitates the insertion of the dental strip 20 into the space between the teeth 42. Once the lead portion 30 passes between the teeth 42, the lead portion 30 is grasped by the dentist and the abrasive portion 26 may be then pulled into the area between the teeth 42 and manipulated to remove any unwanted material between the teeth 42 such as the overhang 46. A back-and-forth or sawing motion is shown by illustrative arrows 50 and 52. The sanding strip 20 is pulled back-and-forth, or in a circular motion, until the overhang material 46, or other unwanted material, is removed.
Having thus described my invention, in reference to the preferred embodiment, it is apparent that there may be modifications or variations of the invention which are within the scope of the invention. There are many different materials which may be used as the lead, and the dental sanding strip may be in one of a variety of different configurations.
