Description

A DENTAL RUBBER DAM CLAMP

TECHNICAL FIELD

[01] The present disclosure relates to dental tools and instruments, and more particularly to a dental rubber dam clamp having a matrix band.

BACKGROUND

[02] Tooth isolation is mandatory for successful functional restoration and successful root canal treatment. Tooth build up prior to root canal treatment is considered important to guarantee success. However, it is time consuming and less cost effective. Matrix band is a cylindrical metal or plastic band with a special clamp or holder (the matrix retainer); it is seated over a tooth so that the restorative material can flow into the prepared cavity. It is also used for placement and contouring of certain restorative materials.

[03] Rubber dam is a sheet of thin latex rubber used by dentists to isolate a tooth or teeth from the fluids of the mouth during dental treatment, held in place by a clamp and frame.

[04] Using the conventional matrix bands and rubber dams during endodontic operations would require the patient to visit the dentists’ multiple times given the nature of these matrices and dam. Thus, providing a tool that achieves tooth isolation and as well as acting as a matrix band will help to restore tooth effectively and efficiently in one visit to the dentist would definitely reduce time and cost with more predictable results.

SUMMARY

[05] It is an object of the present disclosure to provide a dental rubber dam clamp with a built-in matrix band, thus saving the time and effort of a dentist to replace tools during an endodontic operation.

[06] Aspects of the present disclosure provide a dental rubber dam clamp that may include a bracket with a plurality of gripping holes connected to an overlapping band with a first end, a second end, an upper portion, a lower portion, a buccal portion, a lingual portion, a mesial portion, and a distal portion wherein the overlapping band is configured to substantially circumfuse a perimeter of a tooth.

[07] In some aspects, the bracket may have elastic properties that allow for elastic deformation.

[08] In some aspects, the plurality of gripping holes may be configured to receive tips of a clamp holder for applying and removing said dental rubber dam clamp.

[09] In yet some aspects, the first end and the second end of the overlapping band may be in proximity to the buccal portion.

[010] In some aspects of the present disclosure, a thickness of the overlapping band may gradually increase from the lower portion to the lower portion.

[Oil] In some aspects, the overlapping band may be tapered from the upper potion to the lower portion.

[012] In some aspects of the present disclosure, a ratio of thickness of the buccal portion to the mesial portion may be at least about 1.13:1.

[013] In some aspects, a ratio of thickness of the lingual portion to the mesial portion may be at least about 1.13:1.

[014] In some aspects, the overlapping band may have elastic deformation properties.

[015] In some aspects, the bracket may be made of nickel titanium alloy, stainless steel, or a combination thereof.

[016] In yet some aspects, the overlapping band may be made of nickel titanium alloy, stainless steel, or a combination thereof. BRIEF DESCRIPTION OF THE DRAWINGS

[026] FIGS. 1-8 illustrate a dental rubber dam clamp configured according to embodiments of the present disclosure. In embodiments of the present disclosure, the dental rubber dam clamp may include a bracket 1 having a substantially curved shape with a first end 10, and a second end 11, each of the first and second ends 10, 11 may have a gripping hole 2a, 2b respectively, and an overlapping band 3 with a first free end 30, and a second free end 31. The overlapping band 3 may have a buccal portion 300, a lingual portion 301, a mesial portion 302, a distal portion 303, an upper portion 3000, and a lower portion 3001, wherein the upper and lower portions 3000, 3001 are illustratively separated by a virtual dashed line 1000 of FIG. 1.

[027] In embodiments of the present disclosure, the bracket first end 10 may be connected to the buccal portion 300 of the overlapping band 3 in proximity to the upper portion 3000, and the bracket second end 11 may be connected to the lingual portion 301 of the overlapping band 3 in proximity to the upper portion 3000.

[028] The gripping holes 2a, 2b may be configured to receive tips of a conventional clamp holder 4 during application around the tooth and/or removal from the tooth.

[029] In embodiments of the present disclosure, the bracket 1 and the overlapping band 3 may be configured to have elastic properties that allow for elastic deformation when a force is being applied to the first and second gripping holes 2a, 2b using any conventional clamp holder 4.

[030] According to embodiments of the present disclosure, the overlapping band 3 may be configured to encounter and totally isolate the tooth of interest from the remaining teeth in the buccal cavity.

[031] In some embodiments, the first end 30 and the second end 31 of the overlapping band may be in the buccal portion 300. [032] In embodiments of the present disclosure, the overlapping band 3 may be tapered from the upper portion 3000 to the lower portion 3001 in order to allow for a complete isolation of the tooth of interest from the remaining teeth (FIG. 6).

[033] In embodiments of the present disclosure, the thickness 3003 of the overlapping band 3 may gradually increase as going up from the lower portion 3001 to the upper portion 3000. This would render the stiffness of the upper portion 3000 greater than the lower portion 3001.

[034] In some embodiments, the thickness 3003 of the overlapping band 3 in the buccal and lingual portions 300, 301 may be greater than the thickness 3003 at the mesial and distal portions 302, 303, respectively.

[035] In some embodiments, the ratio of the thickness 3003 of the buccal portion 300 to the distal portion 303 may be at least about 1.13:1.

[036] In some embodiments, the ratio of the thickness 3003 of the distal portion 303 to the lingual portion 301 may be at least about 0.88: 1.

[037] In some embodiments, the ratio of the thickness 3003 of the lingual portion 301 to the mesial portion 302 may be at least about 1.13:1.

[038] In some embodiments, the ratio of the thickness 3003 of the mesial portion 302 to the buccal portion 301 may be at least about 0.88: 1.

[039] In some embodiments, the thickness 3003 of the mesial portion 302 and the distal portion 303 may range from about 0.037 mm to about 0.040 mm in order to provide a stable placement around the tooth without distortion at tight intact contact points with the adjacent teeth.

[040] In embodiments of the present disclosure, the overlapping band 3 may allow a dentist to build tooth filling materials using the dental rubber dam clamp of the present disclosure. [041] In embodiments of the present disclosure, the displacement between the buccal portion 300 and the lingual portion 301 depends on the tooth size on which the dental rubber dam clamp is to be installed. For instance, the displacement between the buccal portion 300 and the lingual portion 301 for molars may range from about 9 mm to about 11 mm, and the displacement between the buccal portion 300 to the lingual portion 301 for premolars may range from about 6.5 mm to about 9 mm.

[042] Similarly, the displacement between the mesial portion 302 and the distal portion 303 depends on the tooth size on which the dental rubber dam clamp is to be installed. For instance, the displacement between the mesial portion 302 and the distal portion 303 for molars may range from about 7 mm to 10mm, and the displacement between the mesial portion 302 to the distal portion 303 for premolars may range from about 5 mm to about 7mm.

[043] In some embodiments of the present disclosure, the bracket 1 may be made of nickel titanium alloy, stainless steel, or a combination thereof.

[044] In some embodiments, the overlapping band 3 may be made of nickel titanium alloy, stainless steel, or a combination thereof.

[045] In embodiments of the present disclosure, for the application of the dental rubber dam clamp of the present disclosure, a dentist may insert tips of a conventional clap holder 4inside the gripping holes 2a, 2b and apply a lateral force on the conventional clamp holder 4, the conventional clamp holder 4 will then translate the force onto the buccal and lingual regions 300, 301 off the overlapping band 3 thus elastically deforming the band 3 by increasing the displacement between the buccal and lingual portions 300, 301. Then, the dentist may place the overlapping band 3 around the tooth of interest and take off the clamp holder 4. After that, the overlapping band 3 would return back to about its default undeformed shape and dimensions with the aid of the bracket 1 while encountering the tooth of interest, as shown in FIGS. 7, 8.

[046] Alternatively, for the removal of the dental rubber dam clamp of the present disclosure, the dentist may insert tips of a conventional clap holder 4 inside the gripping holes 2a, 2b and apply a lateral force on the conventional clamp holder 4, the conventional clamp holder 4 will then translate the force onto the buccal and lingual regions 300, 301 off the overlapping band 3 thus elastically deforming the band 3 by increasing the displacement between the buccal and lingual portions 300, 301. Then, the dentist may take off the dental rubber dam clamp.
