Who are We and Why are You Receiving This?

 

In October, 2012, Dr. Dean Mersky formed

A national cooperative of small dental laboratory owners

Dedicated to the growth and viability of Private Practice Dental Offices.

A part of our support is providing doctors with evidence-based

information about materials and techniques key to patient care.

The Challenges We Face

The traditional procedure for enlarging the space between the gum and the base of the tooth necessary for an accurate C&B impression is tedious, time consuming, and too often painful for the patient. Not exactly a great practice builder! Also, in the event the space between the tooth and the gum is tight or very small, it can become even more difficult to place the cord without injury, raising the danger of accidentally forcing the cord beyond the physiologic tissue limits which can cause periodontal complications. Most of us don't enjoy packing cord, sometimes passing it off to others, which can lead to questionable results.

 

Alternatives

One way to retract and control bleeding, if the sulcus is large enough, is to place cord and then pack cotton. We might also soak the cord and cotton with Hemodent (Premier) to help control bleeding. Unfortunately, the extra cotton only spreads the sulcus, might not stay in place, and risks tearing the free gingiva. Recently, there have been two products offered  to clinicians to help with these challenges, one uses only a high viscosity gel to control bleeding, the other Traxodent, from Premier, combines a more flowable gel-paste with an optional pressure pad to stabilize the site.

Traxodent, which is formulated as a clay-based version of Hemodent, has the most advantages in this category of products. Traxodent combines distilled water, Aluminum Chloride Hexahydrate (15% by volume), Potasium Sorbate (a salt of sorbic acid that is a preservative and anti bacterial), and Potassium Nitrate (a salt and preservative that is an oxidizer and anti inflammatory). It is the combination of these components that differentiates and makes Traxodent so effective.

The Chemistry behind How it Works

Astringents are the substances that precipitate proteins, but do not penetrate cells, thus affecting the superficial layer of mucosa only. Astringents, such as Aluminum Chloride, exert their action topically on the abraded mucosal surface, whereas the hemostatic effect of vasoconstrictors is accomplished through a direct vascular action. Aluminum Chloride has been found to be least irritating and may be left in the sulcus for up to 15 minutes without causing permanent damage. In contrast, Ferric Sulfate acts as a clotting agent, and often, when the string is removed, the clot is pulled out with it, causing hemorrhaging. Additionally, Ferric Sulfate doesn't help with tissue shrinkage as do the components of Traxodent.

Traxodent contains a special clay formula that has been designed to flow into the sulcus, unlike other, high viscosity gels, that need to be injected into the sulcus. Similar  in viscosity to light body impression materials, Traxodent retracts tissue by combining an astringent with physical displacement and chemical absorption that serves as a drying agent. This results in an open, dry sulcus with minimal trauma that has also undergone shrinkage.

 

Clinical Guidelines

Because the viscosity of Traxodent is comparatively low, the delivery cannula (18-22 ga) is small and doesn't require sub gingival placement. Additionally, the small diameter cannula can be bent to more easily manage its use and make tight areas more accessible.

Traxodent can be allowed to stand for between 2 and 5 minutes, depending upon the amount of gingival crevicular fluid. Immediately prior to the impression:

  1. Gently rinse the retraction material away
  2. Dry the area around the tooth or teeth
  3. Take the impression

 

Occasionally, obtaining effective retraction will require additional pressure due to inflammation or redundant tissue. The additional step of adding pressure with a specially designed cap placed over the tooth or teeth and gingival sulcus may be used.  The biting pressure of the patient holding the soft cap in close proximity will aid in the retraction of the gingival sulcus. Another variation that can be helpful is a combination technique of packing an initial small cord followed by Traxodent.

 

Summary

We have been packing cords for decades. It is a process that most of us would rather avoid but, we endure anyway. We know that often the tissue won't cooperate or that, in our efforts, we might make things worse. Scientific innovation has provided us with a worthwhile alternative. Relying on a very familiar and popular product that many of us have used, Hemodent, Premier Dental has combined other components that have the capacity to make our lives easier and our patients more comfortable. The Traxodent system can in part or entirely replace one of the most distasteful parts of C&B, cord packing. It is formulated to displace tissue with ease, control bleeding, dry the area, and, help shrink the tissue by reducing inflammation. If this can make everyone's life easier, at the very least, it is worth trying and evaluating personally.

A New Category of Permanent Cement

 

All the Benefits, None of the Drawbacks

The Science Behind Biocactive Ceramir C&B

 

 

Last month we introduced you to Ceramir Crown & Bridge (Doxa) as a new category of permanent cement. We explained its bioactive nature and new-category characteristics. This month, we will explain the science behind it and what that means to the restorative process that benefits our patients.

 

What is Ceramir C&B?

Ceramir C&B is a hybrid composition of Calcium Aluminate and glass ionomer, that when combined with its liquid, undergoes an acid-base reaction similar to hydraulic cements.

The incorporation of the Calcium Aluminate gives several unique properties that separate it from conventional GIC's. After 3-4 hours of setting time, Ceramir C&B changes its pH from a very mild acid to a base of pH of ~ 8.5. The mild and lasting alkalinity allows the continuous formation of apatite when adjacent to phosphate containing solutions.

The alkalinity that the material produces in combination with the dense matrix created fixes the GIC structure and helps prevent the ionomer glass from continuously leaking over time.

The alkalinity also helps with pulpal compatibility. Histological data shows that even at a minimum distance from the pulp, there is virtually no irritation resulting in inflammation.

 


Above, the enamel on the left side of the photo is fully integrated with Ceramir C&B on the right side.

Above, dentin on the right side of the photo has fully integrated with Ceramir C&B on the left side.

Ceramir C&B relies on the mode of hydration by its key component Calcium Aluminate and the ionic bond of the GIC to bond to the tooth. That means, etching enamel or dentin and using a bonding agent aren't needed. Moreover, its hydrophilic nature makes the material insensitive to uptake of  oral fluids, while its alkalinity remains and helps preventing  bacterial growth and sensitivity.

Ceramir C&B has a 2 minute working time, and a setting time of 4-5 minutes. Its film thickness is 15 microns. Its compressive strength at 24 hours is 160 MPa, similar to many resin-based cements, such as Rely x Unicem (157 MPa) but far greater than Rely x Luting's (96 MPa). However, after one month, the bioactive nature of Ceramir C&B boosts its compressive strength to 200 MPa.

Expansion of Ceramir C&B is at most, 0.4%, and is due to the free growth of hydrated crystals associated with the formation of apatite. However, bulk expansion, measured as expansion pressure was recorded to be zero.

During hardening, the ceramic powder will dissolve and the resulting ion solution will penetrate irregularities of the tooth wall. When precipitation occurs it does so mainly in the form of nano-sized hydrates on pre-existing nuclei and filler particles on the tooth wall. This means that the mineral density at the material-tooth interface will increase, resulting in a mineralization.

 

Above, notice the deposition of HA on the surface of hardened Ceramir C&B in the presence of phosphated saliva.

Above, notice the lack of HA formation on PMMA, in the presence of phosphated saliva.

For a distinct layer of HA to be precipitated between the material and the tooth, phosphate ions must be present on the tooth surface.  The low solubility of HA  together with the negatively charged surface of the cement creates an excellent environment for HA growth on the surface. It has previously been shown that the components of the cement are sufficient for formation of a HA layer on the cement surface. Ceramir C&B is the only cement fulfilling the above-mentioned necessary prerequisites. Zinc phosphates are too acidic and do not contribute with Ca ions. Resin-based materials are not alkaline, and do not show extended ion leakage. Glass ionomers have an ion leakage but are acidic and cannot induce HA formation on its surface.

 

When considering cementation, keep in mind the unique properties of Ceramir C&B:

  • Eliminates sensitivity
  • Ease of use similar to RMGI
  • Holding power and insolubility of resin
  • Highly retentive of zirconia (due to nano particles).
