Definitions
- the most common purpose for using a retraction cord is to retract the gingiva away from the tooth to take an accurate and reliable impression of the tooth. It is important to make an accurate impression of the tooth when constructing artificial crowns to ensure that the crown remains properly secured to the tooth for an extended period of time. It is particularly important to make an accurate impression of the tooth in the area at or below the gingival margin. Failure to take an accurate impression can result in a poorly-formed or deficient prosthesis, particularly at the gingival margin. Premature failure of a crown is often due to poor marginal detail in the impression used to fabricate the crown.
- the person's gingiva not only prevents an accurate impression of the proper shape of a person's tooth beneath the gingiva, it may also bleed if torn or damaged by high speed cutting drills or burrs used to remove tooth material preparatory to placing a crown. This bleeding may further interfere with the taking of a good impression because extravasated blood tends to prevent adequate cleaning and drying of the marginal area of the tooth prior to taking an impression and tends to displace the impression material before it can set.
- the dual problems of contraction of the gingival cuff and the presence of hernorrhaging tissues make it impractical to simply take an impression following shaping of the tooth with a high speed drill or burr without retraction of the gingiva.
- retraction cords are made of knitted or braided cotton fibers.
- the hemostatic agent or astringent placed in the retraction cord can degrade the cord over time making it more likely to fail during use. If fibers in the knit or braid fail during use, the dental packing instrument used to insert the retraction cord into the sulcus can slip through the fibers and potentially cut or injure the underlying tissue. In addition, fragments of the retraction cord can remain embedded between the tooth and gums. Furthermore, the expandability and resilience of the retraction cord diminishes as the integrity of the knit or weave of the cord degrades. Therefore, what is needed is a gingival retraction cord that can properly retract the gingiva using a hemostatic agent while also resisting degradation due to the hemostatic agent.
- a knit pattern of the present invention is that it is resilient in the radial dimension.
- the strands and fibers in the knit retain a certain level of memory when compressed. As the fibers tend to return to their original position, the gingiva is pushed out radially.
- the blend of fiber materials used in the retraction cord of the present invention retains the benefits of a knit pattern by including each fiber in the knit pattern. Blends of absorbent, synthetic, and metal strands or fibers can provide the retraction cord with beneficial characteristics without compromising the benefits derived from a knit pattern.
- Strand Pattern Retraction cords can be made using any of various techniques, including knitting, braiding, weaving, or twisting.
- two common types of knitting techniques that can be used to form the retraction cords of the present invention include knits made from an "open” loop and a "closed loop.”
- the "open" loop shown in Figure 1 is formed using a first loop 10a that is interlocked with an adjacent loop 12a such that ends 14a and 16a of loop 10a do not cross one another.
- Figure 2 illustrates what is generally known as a "closed” loop knit.
- the end 16b of first loop 10b bends back over and crosses in a manner that closes off the loop 10b.
- Figure 3 illustrates two rows (generally designated at 18a and 20a) of interlocked loops constructed utilizing the open-loop configuration shown in Figure 1.
- row 18a includes a plurality of loops 10a, which are interlocked with loops 12a of adjacent row 20a.
- Figure 3 illustrates "weft" knitting, which is made from one loop to the next in the same course, or row, of loops, and which can be done using a first strand 21a for row 18a and a second strand 21b for row 20a. Alternatively, weft knitting can be performed using a single strand or more than 2 strands.
- strands 21a and 21b are a blend or can include a blend of different materials to give the retraction cord beneficial properties such as resistance to the degrading effects of a hemostatic agent or other corrosive material.
- Figure 4 alternatively, illustrates three rows (generally designated at 18b, 20b, and 22b, respectively) of interlocked loops constructed utilizing the closed-loop configuration of Figure 2.
- row 18b includes loops 10b, which are interlocked with the loops 12b of adjacent row 20b. Loops 12b of row 20b are in turn interlocked with the loops 24b of adjacent row 22b, and so on.
- Figure 4 illustrates "warp" knitting in which several strands 26, 28, 30, and 32, are interconnected such that the interlocking loops of each strand connect from one row to the next.
- the knitted strands can be made of one or more different materials to give the retraction cord advantageous properties.
- Figure 5 shows a gingival retraction cord 34 knitted from four strands 36, 38,
- the knitted retraction cord of the present invention can be constructed using either an open-loop or a closed-loop pattern or system, as shown in Figures 1-5. Retraction cord 34 can also be made using other kitting patterns so long as the knit pattern provides sufficient elasticity and/or resilience. Furthermore, those skilled in the art will recognize that the knit pattern can include any number of strands and each strand can be made from any number of fibers.
- the two or more sfrands are interlocked to form a braided, woven, or twisted retraction cord.
- Figure 9 illustrates an exemplary braided cord 60.
- Braided cord 60 has four pairs of strands 62, 64, 66, and 68, which each include an "a" strand and a ⁇ b" strand.
- the braid is formed by taking the leftmost strand pair and passing it under over and then under successive strands to the right. To illustrate this pattern, the braid in Figure 9 would be continued by taking strand pair 62 (i.e. strands 62a and 62b) and passing it under strand pair 64, over strand pair 66 and under strand pair 68.
- strands 36, 38, 40, and 42 are a blend of strand materials.
- strands 36, 38, and 40 are cotton strands and strand 42 is a synthetic polymer such as nylon or polyester.
- strand 42 can be a ceramic, carbon-based, or thin metallic strand having a thickness less than about 2 mm.
- strands can be made from more or fewer absorbent fibers and/or degradation-resistant fibers such that the retraction cords of the present invention can have almost any desired blend ratio.
- blended strands can also be blended with other blended or non-blended strands to create a retraction cord having a desired absorption, resistance to degradation, or resiliency.
- Materials used to create the blends of the present invention include natural and synthetic polymers, coated polymers, metal filaments, or any other threadable material that can give the retraction cord a desired property. For instance, cotton can be used for its absorbency, low, cost, and biocompatibility.
- a polymer fiber or metal filament can be selected to give the retraction cord a desired resiliency, elasticity, or deformability.
- a metal filament such as silver can also be included to make the retraction cord radioopaque.
- Other suitable materials include carbon fibers and filaments and ceramic fibers (e.g., fiberglass).
- a synthetic polymer such as nylon or polyester is included in the knit of the retraction cord to resist degradation by an active agent.
- active agents such as hemostatic agents can be included in the retraction cord of the present invention to assist in controlling bleeding of the gingival during a procedure. Active agents that are corrosive can break down absorbent fibers such as cotton.
- a synthetic polymer such as nylon or polyester is included in the knit to resist degradation and thus failure of the retraction cord. Preventing the failure of the knit helps ensure that the retraction cord properly retracts gingival tissue and reduces the chances that a packing instrument will pierce the knit of the cord and damage the underlying tissue.
- the non-degrading fiber or filament can be blended into the knit through a strand or through individual fibers. In this regard, it can be advantageous to include the non-degrading material as a fiber in each strand of the knit. In this manner, each sfrand is structurally supported and improved by the blend of fibers.
- Knitted, braided, woven, and twisted cords all have certain flexibility, resilience, and packing properties. Unlike attempts in the prior art, the blends of the present invention do not prevent the natural movements of the cord because the degradation-resistant strands and the absorbent strands form part of the knit, weave, twist, or braid and are flexible.
- the knitted retraction cord 34 of Figures 5 and 6 is characteristically highly elastic and resilient in both the longitudinal and transverse dimensions.
- Each of the strands 36, 38, 40, and 42 used to create the blended cord are formed as part of the knit of retraction cord 34 so as to not disrupt the advantages provided by a knit pattern.
- Cord 34 can be easily stretched along its length, and squeezed or compressed radially because of the properties of a knit pattern.
- a knitted cord the strand or strands are oriented so that a portion of each strand runs transversely, or at approximately right angles to the longitudinal axis of the cord, thus making the cord more compressible and also more stretchable along its length.
- a twisted- strand or braided-type cord has less longitudinal or transverse elasticity.
- the blends of the present invention do not prevent the movement of the cord in the transverse and/or radial dimensions because in the present invention each strand is part of the knit pattern.
- active agent such as a hemostatic agent. Hemostatic agents, including astringents and other vasoconstrictors, can be impregnated in the retraction cord to control bleeding and stiffen gingival tissue.
- Active agents that may be useful in assisting hemostasis include, but are not limited to aluminum compounds such as potassium aluminum sulfate, aluminum ammonium sulfate, aluminum sulfate, aluminum chlorohydrate, aluminum acetate, other water soluble astringent aluminum salts, and mixtures thereof.
- Another class of astringents includes iron-based compositions such as ferric salts, including but not limited to ferric sulfate, ferric subsulfate, ferric chloride, and mixtures thereof.
- Other astringents include permanganates, tannins and zinc chloride.
- the active agent is a vasoconstrictor such as epinephrine and/or propylhexedrine.
- a dental instrument 50 pressing the gingival retraction cord 34 within the sulcus 52 between the gingival cuff 54 and the tooth 56.
- the resilience and flexibility in the transverse direction allows the knitted refraction cord 34 to conform to irregularities, such as the margin 58 of the tooth 56. Even if the loops of the knitted refraction cord are left rather loose, because of the intricate interlocking network, there is little or no tendency for the dental packing instrument to slip through the refraction cord. Rather, the compressibility of the knitted cord 34 causes the cord 34 to "dimple" around the edges of the dental packing instrument 50.
- knitted retraction cords Because of the compressibility and bendability of knitted retraction cords there is less of a tendency for the cords to damage underlying gingival tissue as force is applied during packing. This is because the force of the packing instrument tends to be spread out over a larger area by the interlocking loops of the knitted cord. Also, the transverse resilience of the knitted cord enables it to conform to irregularities within the sulcus. Thus, the knitted cord can accomplish both horizontal and vertical retraction using a single cord. Another advantage of knitted retraction cords is their tendency to return to their original, uncompressed shape because of their resilience.
- the lingual gingival tissue can be adequately retracted with the knitted refraction cord only slightly compressed, and by virtue of its compressibility and its ability to stretch and become thinner, the same cord can be packed into the sulcus on the labial side of an interior tooth without over-retracting the gingival tissue.
- the cord then exerts a general, steady outward force on the tissue, which is desirable.
- Another feature of the retraction cord of the present invention is that it can be chemically impregnated with an active agent over an extended period of time without compromising the knit pattern and the benefits that accompany a knitted cord.
- the degradation-resistant fibers or strands blended into the knit of the refraction cord permit chemical impregnation yet give the retraction cord strength in the event that the active agent degrades other fibers in the cord. While there are many benefits for using a knitted cord, in some cases, braided, woven, or twisted retraction cords can be preferred. This preference can be because of the cost to manufacture a particular cord, or because of the experience that a practitioner may have with a particular type of retraction cord. In any event, braided, woven, and twisted cords are improved by including a combination of an absorbent strand and a degradation-resistant strand according to the present invention.
- the braided, woven, or twisted retraction cords of the present invention benefit from having the degradation resistant strands or fibers used in the braid, weave, or twisted pattern.
- the braided, woven, or twisted retraction cords bend and pack in a manner that is typical of the particular strand pattern type.
- the retraction cord bending and packing properties are not substantially affected by the inclusion of the degradation resistant strands.
- the braided, woven, or twisted retraction cords can be impregnated with an active agent and resist degradation of the cord by the active agent.
- the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
