Mini-Bristle Brushes & Mini Cotton Buffs

Description & Application

The DVA Mini Bristle Brushes and Mini Cotton Buffs are two extremely unique polishing instruments which are ideal for the intra-oral polishing of ceramic or composite restorations. This unique family of useful rotating instruments includes Mini Bristle Brushes and Mini Cotton Buffs. Both are 7/16” (1 cm.) in diameter with a latch type contra-angle shank. The total diameter of each wheel is approximately half the diameter of a dime!

The Mini Bristle Brush is designed for polishing all types of ceramic restorations and the Mini Cotton Buff is designed for polishing all types of composite restorations. However, with the appropriate polishing medium, both wheels provide an outstanding finish to most dental materials; such as metal, acrylic resins, acetal resin, lithium disilicate, lucite-based ceramic and thermoplastic materials. DVA’s Mini Brushes and Buffs are available in either packages of 100 pieces or a combination package containing 50 Mini Bristle Brushes and 50 Mini Cotton Buffs.

Acryl-Marvel Adjustment Kit

Acryl-Marvel, a new polish for simplifying the finishing and re-polishing of dentures that required some final adjustment. The special compound is supplied in small individual shapes designed for use with only one patient.

Cross-contamination prevention procedures are thereby significantly reduced. The polish eliminates the scratches and trimming markings and high-shines the denture in one, continuous operation. No pumice is necessary. The resultant hi-shined, polished surface is extremely silky and lustrous; extremely resistant to the build-up of calculus.

Star Porcelain Brushes

Description & Application

Being in a position to introduce product that virtually takes a technique to another level is very exciting. That is exactly what the STAR BRUSH Line does! They provide a level of performance with regard to the tip integrity, moisture management, porcelain manipulation, and durability far beyond any other brush on the market.
As our brush motto indicates, “Brushes are brushes, but ours are STARS!”

Dental ceramists build porcelain to shape, prior to placement into the firing furnace, either using a brush or they “stack” porcelain utilizing a metal instrument. For those that build with a brush, their “tool of choice” becomes very, very significant as in ‘of critical importance.’ It would not be incorrect to state, “their search for the ideal brush is a life-long endeavor.”

The evolution of the acceptance and popularity of ceramic brushes has ‘pretty much been dependent and driven by the
ability of brushes to display these features. In general, the more expensive brushes, supposedly manufactured in Germany have grown to be accepted as the standard.

However, those customers having tried DVA’s new “STAR BRUSHES” report they excel in all areas of performance! Hence, we enter the market with a great opportunity, always keeping in mind, the acceptance of any dental product, and brushes would certainly be included, is a very personal decision. We probably cannot please everyone, but we certainly can please most!

Types of Brushes

Brushes traditionally could be divided into two general classifications:
1. Synthetic (Mostly made from nylon)

2. Natural (Produced from the hair fibers of animals) The ‘natural’ brushes have evolved into the acceptance of two general classifications of brushes – Red Sable and Kolinsky Sable. Red Sable brushes, so referred to because of their ‘reddish-brown color,’ are produced from the weasel animal; while the Kolinsky brush is made from a mink (also of the weasel family) that is native to Siberia and northeastern China, where the extremely cold weather causes the development of a thick, long coat of hair. Only hairs from the tail of these animals are used in making dental brushes.

Comparative physical characteristics of the two types of brushes can be described as follows:

Hair Fiber Thick; good tip; ‘spindle’ shape Thin; better tip; ‘belly shape’
Color Rather Dark More ‘yellowish’
Flexibility/”Bounce-back” Best Good
Liquid Retention Good Better
Luster Good Better
Shape of Head “Spindle-like” “Barrel-like”
Smoothness Good Better, shiny and smooth

It is IMPORTANT TO NOTE that while the KOLINSKY brushes are, in general, more expensive, the acceptance of any ceramic brush is a function of its performance as perceived by the individual using it!

DVA offers those brushes as perceived as the ‘most critical’ with respect t building porcelain in the highest quality of Kolinsky fibers available. Most importantly, the source of the fibers for our manufacturer, based upon their generations of involvement with the manufacturing of fine brushes, is consistent.

There is one other brush that is included in our line – a rather large brush, shaped in a thick, somewhat ‘shovel-like shape” that is used to ‘withdraw’ moisture from the porcelain prior to placement into the firing oven. This brush is used in a ‘whipping motion’ to cause any moisture to come to the surface and be ‘whipped away.’ This action also condenses or packs the porcelain to some degree.

Again, reports from our testing customers have indicated this particular DVA brush, made from the hairs of the GRAY SQUIRREL, is much more effective and works faster than the brushes previously available. It seems to be somewhat firmer and thicker than the competitive brushes. It is fast, quick and effective!

It is very important to note that while many, many different brushes are on the market, DVA’s focus must not be on competitive brushes, but rather the PERFORMANCE of our “STAR LINE!” They just do what porcelain brushes should do – “They Perform,” and they do so like STARS, and they are PRICED COMPETITIVELY! THAT is what we need to sell! Just provide the customer with ASSURANCE, ASSURANCE, ASSURANCE that they are going to be happy with DVA’s STAR brushes.

Descriptions & Prices

Dental Ventures will offer a broad line of brushes to meet all of the demands of the ceramist. We will NOT offer every size, but we will offer a variety that seems to fulfill the needs of most technicians.

We will offer sizes 00/0/6 in RED SABLE, and the numbers 8 and 10 in the Kolinsky style.

Dip N’ Cast Wax

Dip N’ Cast is a wax used for dipping and coating dies. The wax ingots are available in two consistencies and each consistency in two colors. Firm consistency is available in Green and a Yellow color and the Flexible consistency in Green and Orange colors.

Product Application:

Dip N’ Cast is a wax that is melted to a liquid state in a heated dipping pot at a preset temperature. It is used to apply a uniform layer of wax in a given thickness desired by the technician to the surface of a die that is dipped into and quickly removed from the liquid wax. The choice of wax consistency and color is the decision of the technician.

Compared to competitive products, DVA’s Dip N’ Cast is characterized by:

  1. A lack of shrinkage such that generally, the re-sealing of die margins can be eliminated.
  2. The wax pattern can be removed, replaced and reseated without having to seal or reseal the margins.
  3. Demonstrates incredible consistency in dipping thickness and memory retention.

SPECIAL NOTE: Whereas a single, normal dipping thickness would provide a “normal PFM coping” layer of typically four- tenths of a millimeter in thickness, ONLY the very unique formula of DVA’s Dip N’ Cast allows the Double Dipping to quickly and uniformly obtain the recommended eight-tenths of a millimeter desired for the fabrication of Press-Ceramic Copings. “Double Dipping” without changing dip-pot temperatures or problems with wax layering! A BIG BENEFIT!

Product Benefits

  • Increases Productivity
  • Improves cleanliness and fit of castings
  • Eliminates necessity to seal margins
  • Insures ceramic compatibility
  • Allows ‘Double-Dipping’ for Unique Formula Cast Ceramic Copings

Product Features

  • Consistent dipping thickness
  • Eliminates necessity to seal margins
  • Trims extremely sharp and clean
  • Lack of internal shrinkage lines
  • Reduced shrinkage
  • High-quality, ash-free formula

Jerry’s WOW Solution

Description & Application

DVA’S “Jerry’s WOW Solution” consists of a silicone-based liquid packaged in a 16-ounce bottle designed for use as a gypsum-to-gypsum separator. The product is characterized by its lack of odor, incredibly clean separation capabilities and economical price.

Jerry’s “WOW Solution” derives its name from its outstanding performance and economy. Nothing separates gypsum like “WOW Solution.” It’s just a “WOW” product!

Background of Product Use and Competition

There are three basic types of dental separators:

. Acrylic Separators – designed as a tin-foil substitute. Tin foil was the original separator medium used to separate denture acrylic from the stone model during polymerization procedures. Many companies now sell a separator for this procedure. DVA’s “Acrylic-Plaster Separator” (“APS”) represents a separator of this class.

. Crown and Bridge Separators – designed to separate wax patterns or porcelain margins from stone models. DVA’s “Very Special Separator” is a separator of this class.

. Gypsum Separators – designed to separate dental stone from either stone or plaster. The “WOW Solution” represents this type of separator. Gypsum separators have three basic uses:

i. They are used to separate halves of a denture flask. Vaseline (as well as other competitive products) has also been used extensively for this procedure.

ii. For the mounting of articulating plaster to full or partial denture models for use during the setting up of teeth during the fabrication of the wax pattern. Again, Vaseline and other products have been used for this operation.

iii. To separate the first, arch pour and the second, base pour of a standard, ‘pindex-type model. It is this widely-used application for which we anticipate DVA will concentrate its sales efforts on behalf of the “WOW Solution.”


WOW Solution PIM

The market leader used for these applications appears to be ‘Super-Sep’ by Kerr Manufacturing. “Super-Sep” is an alcohol-based liquid characterized by an extremely strong ‘alcoholic’ odor. It

is also, compared to DVA’s new product, rather expensive. DVA offers twice the volume at virtually half the price.

As successful in the marketplace as it is, we do NOT believe ‘Super-Sep’ is as effective in its separation ability as DVA’s WOW Solution! Need we say more!

Product Benefits

  • DVA’s “WOW Solution” gypsum separator
  • Totally Eliminates Odors from the working environment – it is totally odorless!
  • Improves Separation of gypsum products – it simply performs better than competitive products! “WOW” only requires one, single application, and it
  • Eliminates the need to re-soak dry models prior to making second pours.
  • Saves Money – One receives ‘twice the product for half the price!’
