Deflex

A new look at Deflex M10XR thermoplastic materials

Dental technicians who manufacture flexible dentures already have their proven materials and work technologies that guarantee good results. However, they invariably struggle with problems resulting from the physicochemical characteristics of thermoplastic materials. At the end of 2015, a new thermoplastic material Deflex M10XR appeared on our market and there are many indications that this is an opportunity to solve several problems with performing these works.

One of the most common disadvantages when working with thermoplastic materials is their thermal shrinkage. It requires strict adherence to the specified thickness of the denture plate, which limits the design freedom. With too coarsely modeled elements, high material shrinkage results in the work mismatching the model. It is an irreversible error and it is practically impossible to correct. The Deflex M10XR has much less stringent requirements. Its minimal contraction (0.3%) significantly reduces the risk of mismatching the prosthetic restoration. There are also no thinning inside the prosthesis, so characteristic of too thick nylon or acetal plates. We work on any class IV plaster, and the accuracy of fitting is so great that even extensive dentures adhere well to the base. Thermoplastic materials based on polyamide and acetal, unfortunately, cannot be easily repaired. They do not combine chemically with acrylic, and the possible supplementation of nylon dentures with "extra injection" is very time-consuming and expensive. There are also methods of joining with adhesives, but ultimately, as a result of differences in the flexibility of the bonding and the bonded material, the materials delaminate and penetrate into the sediment spaces.

The new Deflex M10XR material stands out from traditional thermoplastics because it is polymer-based and has a high ability to chemically bond to acrylics when the material's surface is activated with monomer. This process requires no special bonds or procedures. It is enough to moisten the surface with monomer and apply the material, just like in the case of repairing classic acrylic dentures. This combination is effective, takes much less time and does not cause additional costs. This results in the following advantages: - easy and inexpensive repair of the denture, - the possibility of relining the denture, - the possibility of sticking the teeth into the denture shaft, - the possibility of inserting acrylic teeth into denture in a very limited space, when the artificial teeth must be very short or narrow. It is worth mentioning the aesthetic qualities of Deflex materials. Against this background, it looks very favorable. It looks like nylon, it is available in transparent and pink colors based on transparent. The so-called the chameleon effect masks it well in the patient's mouth. Its stiffness is similar to acetal. It is easy to work with, and when processed with a cutter, it "threads" much less than nylon. After polishing, it obtains a high gloss, similar to acrylic.

After years of presence on the market of nylon materials (polyamides) and acetals, apart from their undoubted advantages, some weaknesses have also emerged. The new thermoplastic material Deflex M10XR introduces a new quality and gives new possibilities of making prostheses, therefore it is a good alternative to existing solutions and extends the offer with works that have not been possible so far.
