Definitions

  • the present invention relates in general to dental dams utilized in the orthodontic and oral surgery fields. More particularly, the present invention relates to a means for more safely and efficiently retaining and stabilizing the dental dam. Specifically, the present invention relates to an improved dental dam stabilizing method and device, providing means for permitting one-handed installation and removal of the device, the device having characteristics that prevent injury to the patient's tooth cementum or to the gingival tissue while still providing a clean dry work area for the practitioner.
  • the rubber dental dam is known in the art and has been utilized in dentistry since 1864. It comprises a thin flexible piece of rubber employed to isolate one or more teeth during various dental procedures.
  • the purpose for using the rubber dental dam is to provide an optimum working environment for the dentist while protecting the patient during operative procedures.
  • the dam not only eliminates saliva from the field of operation, but also mildly retracts the soft tissue around the tooth, particularly when the operative procedure is a class V type operation.
  • Most procedures in operative dentistry are performed more efficiently by employing a dental dam as it assures a dry working area during all steps of the procedure. This is particularly true when an operation is on a carious lesion where the pulp may be exposed; the dental dam then minimizes pulpal contamination.
  • Another advantage to operating in a dry field is that dental restorative materials do not develop their full properties in a wet operating environment.
  • the rubber dam then permits a dentist to obtain the expected physical properties of materials because of the dry field.
  • the dental dam also protects the patient and the practitioner.
  • the rubber dental dam protects the patient from the possibility of aspirating or swallowing debris. Also, the dam will permit prompt recovery of small instruments such as thin files dropped during the operative procedure.
  • the dental dam also affords the practitioner protection from any infectious disease that may be present in the patient's mouth.
  • the dam can first be placed around and attached to a Young holder, which is a frame for the dental dam. Holes are subsequently punched in the dam such that each hole corresponds to a tooth for placement thereover. The dental dam is then lubricated to facilitate the passing of the dam through the tooth crown contact points. Alternatively, the holes are punched first, the dam is installed over the teeth and is then stretched over the frame. In either order, the dental dam then must be stabilized by a retainer means.
  • the retainer clamp is the most common prior art form of stabilizing a dental dam and consists of four prongs and two jaws connected by a bow.
  • the problem with utilizing a retainer clamp is that the clamp is not ideally configured for a specific tooth. Due to the variation in teeth across a single mouth, from sharp thin incisors to broad wide molars, many type of teeth are encountered. Further, every mouth has different sizes and shapes of teeth. As a result, with specific clamps designed for specific teeth, many types of retainer clamps need to be stocked by the practitioner.
  • Another disadvantage in employing the dental dam retainer clamp is that the four prongs must contact the tooth, if they do not, the clamp may need to be ground, a process requiring still more time. Furthermore, even with four point contact, the retainer can injure the gingiva, as well as the tooth, resulting in post-operative soreness. Accurate placement of the clamps is difficult to achieve and as a result, the patient may need to be anesthetized allowing for more comfortable retainer placement on the anchor tooth. The clamp may also create sealing problems on the anchor tooth which then creates leakage problems of wetness into the work area.
  • the Frajdenrajch patent discloses a tool for permitting one-handed installation of MAXiAN'S separators.
  • the tool allows an operator to stretch the separator and place it between teeth using only one hand, thus permitting the practitioner to install the separator without necessitating two hands in the patient's mouth.
  • Yet another object of the present invention is to provide a retaining device, as above, that comprises an elastomeric web section connected to a pair of elastomeric heads that become partially elongated when the retaining device is installed, thereby becoming wedged into the spaces between adjacent teeth.
  • the present invention provides a device for retaining a dental dam positioned in the mouth of a patient comprising first and second heads; an elastomeric web connecting the first head to the second head; the elastomeric web having a first cross-sectional area at relaxation and a second cross-sectional area at elongation of lesser dimension than the first, the second cross-sectional area being interposed between a pair of adjacent teeth and over the dam in position with respect to the teeth, wherein the second cross-sectional area expands toward the first cross-sectional area and forms an elastomeric wedge between the teeth to retain the dam.
  • the present invention also provides a method for retaining a dental dam comprising the steps of positioning a dental dam over a plurality of teeth in the mouth of a patient; selecting a retaining device having first and second heads connected by an elastomeric web section; elongating the web section by urging the heads apart from each other thereby reducing the cross-sectional area of the web section; interposing a portion of the elongated web section between at least two adjacent teeth and over the dam; and allowing the elongated web section to expand toward its original cross-sectional area thereby prohibiting the removal of the dam from the teeth.
  • the present invention further provides in combination, with a dental dam having a plurality of individual holes to fit over a like plurality of teeth in the mouth of a patient, a retaining device having first and second heads, the first and second heads connected by an elastomeric web having a first, relaxed diameter and a second elongated diameter of lesser dimension than the first, the second diameter being interposed between a pair of adjacent teeth and over the dam in position with respect to the teeth, wherein the device forms an elastomeric wedge between the teeth to retain the dam.

  • the representative retaining device 10 is depicted in operative association with a dental dam 11.
  • Dental dam 11 comprises a flexible rubber sheet which can be stretched over a frame member 12.
  • Such frames are known in the art as a Young frame and comprise a curved rim 13 that fits about the patient's jaw and opposed legs 14 and 15, somewhat perpendicular thereto.
  • a plurality of radially extending tongs 16 are provided along the edge 18 thereof to engage the dam 11, which is stretched thereover.
  • the retaining device 10 provides a pair of heads 20 connected by a web 22.
  • the web 22 is constructed from an elastomeric, non-toxic material such as natural rubber, thermoplastic elastomers or other high elongation, low hysteresis materials.
  • the heads 20 are also fabricated from the same elastomeric, non-toxic material.
  • the heads 20 are generally disk-shaped and may have diameters greater than their thicknesses. The attachment of the heads 20 to the web 22 is approximately at the center of the sidewall 24 of each head 20.
  • the cross section of the web 22 in the preferred embodiment is rectangularly shaped, as shown in Fig. 7.
  • the web 22 is disposed such that the shorter side 25 of the rectangle falls in a plane that is perpendicular to the upper surface of the heads 20.
  • Each head 20 has a passage or bore 26 therethrough for slidably engaging a prong 28 of a tool 30 (Fig 3).
  • each passage 26 is perpendicularly disposed with respect to the upper surface of the heads 20.
  • the tool 30 may be manipulated with one hand to spread the heads 20 away from each other thereby elongating the web 22.
  • the cross-sectional area of the web 22 decreases from a first relaxed area 32 to a second elongated area 34. Generally, the decrease should be approximately 50 percent.
  • the web 22 may be interposed between adjacent teeth 38.
  • the web 22 may rotate to allow its smallest dimension to pass between the teeth.
  • the web 22 is rectangularly shaped, and the height 25 of the rectangle is less than the width 35.
  • the rotated web 22 is shown in Fig. 4C.
  • the degree of rotation depends on the dimensions of the web 22 and the amount of the space between the adjacent teeth 38. In some situations, the web 22 will not need to rotate to be interposed between the teeth 38.
  • the tensile force on the heads 20 of the device 10 may be released and the cross-sectional area 34 expands between the two adjacent teeth 38, as shown in Fig. 4D.
  • the web 22 fills the area 39 formed between the bases of two adjacent teeth 38, and the gingival mucosa 40, thereby supplying a force upwards against both tooth crowns 38, and downward against the dental dam 11 effecting retention and stabilization of the dental dam 11.
  • the heads 20 of the device may contact the adjacent teeth 38. When this occurs, the web 22 will urge the heads 20 into the space between the teeth, thereby slightly elongating the heads 20.
  • the heads 20 are elongated, they will more completely fill the spaces between the teeth 38, forming a stronger wedge.
  • the amount of elongation of the heads 20 depends on the width of the teeth compared to the length of the web 22 and the dimensions of the web 22 compared to the dimensions of the heads 20.
  • the retaining device 10 being elastomeric, will reduce injury of the gingival tissue 40 because the tissue will force the web 22 to deform, thereby applying pressure on the retaining device 10, instead of the retaining device 10 applying pressure on the tissue 40.

  • FIG. 8A-8D square (8A), round (8B), oval (8C), and triangular (8D) cross-sectional profiles are depicted. It is also to be noted that the present invention may be utilized in most all teeth spacing arrangements inasmuch as differing sizes and shapes of the web 22 can be provided to fill larger or smaller teeth spaces. When the practitioner encounters a large space between teeth, a retaining device having a correspondingly large web 22 to fill the large space between the teeth is selected. Similarly, small web sizes may be used between closely spaced teeth. The different sizes and shapes may be color coded to allow a practitioner to quickly and accurately identify the various configurations. Furthermore, as shown in Fig.
  • the web 22 may connect the sidewalls 24 of the heads 20 at a location offset from the center of the sidewalls 24, such as the upper or lower edge 42. In the embodiment depicted in Fig. 8E, the web 22 connects with the heads 20 at one edge of the sidewalls 24.
  • the change in location of the connection allows the heads 20 to provide more or less contact with the dental dam 11 after the retaining device 10 is installed. For instance, if the retaining device 10 is installed with the web connection toward the dental dam 11, the heads 20 would not contact the dental dam 11 as much as they would if the retaining device 10 were inverted.
  • a different style of tool 50 for engagement with the heads 20 is depicted.
  • the tool 50 provides a pair of forked ends 52 that straddle the web 22 and push against the sidewalls 24 of the heads 20.
  • An advantage of this tool 50 is that the practitioner is not required to align prongs 28 of tool 30 with the holes or passageways 26 in the heads 20. Of course, for use with the tool 50, the holes 26 are not required but neither do they hinder operation if provided.
  • An advantage of the present retaining device 10 is the ease of installation and removal. An assistant or a practitioner can easily install the dental dam 11 with a retaining device 10 according to the present invention using a tool 30 or 50 that permits one-handed operation.
  • the device 10 may be installed and removed with one hand because the web 22 may be elongated using a one-handed tool 30 or 50 that moves the heads 20 away from each other. Therefore, to retain a dental dam 11 using the present invention, the practitioner first positions the dental dam 11 over a plurality of teeth as shown in Fig. 1. The practitioner then selects a retaining device 10 having dimensions corresponding to the space where the retaining device 10 is to be installed. The practitioner then engages the retaining device 10 with a tool 30, 50 by either inserting the prongs 28 of the tool 30 into the passages 26 in the heads 20 or by engaging the web 22 with the forked ends 52 of the tool 50. This position is depicted in Fig. 4A.
  • the practitioner elongates the web 22 by operating the tool 30, 50 as shown in Fig. 4B.

  • the web 22 contacts the teeth and forms a wedge, as shown in Fig. 4D.
  • the practitioner then removes the tool 30, 50 from the retaining device 10 and installs other retaining devices 10 as needed. To remove the devices 10, the practitioner simply reverses the installation steps.

This occurs because teeth have generally rounded edges when viewed from above as shown in Fig. 1, and from the side as shown in Fig. 2. When the web 122 is interposed between adjacent teeth, the wider areas of the web section 122 fill the larger spaces between the teeth. As the web 122 contracts, portions of the heads 120 are slightly elongated and pulled into the areas between the teeth.

  • the amount of elongation depends on the width of the teeth compared to the length of the web section 222. For instance, if the teeth are relatively thin compared to the length of the web section 222, there will be less elongation of the heads 220 than there will be when the teeth are relatively thick. When the ends of the heads 220 are elongated and pulled into the space between the teeth, the elongated head sections work together with the web section 222 to form the wedge between the teeth and the dental dam 11.
