Yes, as I said before bre-crystal, acry free, flexite mp are the current offerings of thermoplastic PMMA I am aware of.
If we are losing something in translation I am sorry...be it ivo-capsules or handmixed Diamond D.....heating will initiate/accelerate cure leaving you with a solid mass. This mass should there have been initial residual formaldehyde will likely still contain it within the matrix. This is why injection pellets must be vacuum aged. The plain and simple of it is....while I am sure you have a scientific background, and are probably a decent dentist you are not an FDA licensed medical manufacturer, the expense to become one, and the required annual expenses is hard to justify unless you dont want to be a dentist anymore and want to be a manufacturer. ADA approved materials are only approved for use when used in accordance to the manufacturers instructions....so even if you skirt the FDA your still in troubled waters.
As I said before, if the companies I have mentioned products do not meet your needs....contact them and contract a batch to your specifications.
Do you ever have a client who has been playing dentist at home....cleaning their own teeth with metal pics...etc....Do you not believe that there is a call for relying on properly trained professionals within their specific field?
Thanks for confirming....In truth I already knew but thought the comment would benefit others understanding of what you are doing. As I have mentioned in the past the use of thermoplastic acrylic is still pretty uncommon and few technicians are well versed in its nuances.
Institutions reject radical ideas, Radical ideas that survive eventually grow into....Institutions that reject radical ideas. Early adopters of any technology or technique are oft faced with the dichotomy of trying to teach what they are doing, so others understand, while they themselves are still struggling to. There are serious benefits to thermoplastic systems...but unfortunately at this time, there arent a great number of options in providers...yet.
Heating prior to injection: Yes, I agree with what you are saying, but I am only advocating heating to 60 Celsius, so will this also have the same effect? Will I lose the material by heating only to that lower temerature?
Also, if I am heating prior to injection, but otherwise following manufacturer requirements, it is a non-issue. Besides, dentists always vary things somewhat. Take as an example amalgam. By law if we spill any we are required to call EPA for a cleanup, yet, do you really think any dentists do that? By law, if you break a fluorescent bulb you must call the EPA, as again it contains mercury, but have you ever done so? Thus, the variations issue is a moot point, and only becomes an issue when something goes wrong.
Per thermoplastic systems, I totally agree; the fields are limited, in techs trained, in materials. Say I am successful, and order gobs of said materials. This will cause the fields to expand exponentially, as other ofices will get on board.
Take as an example a primary competitor of mine. He is challenging my advertising to the state board. He does not want me to advertise that I use better quality impression materials, or anything for that matter that result in a better denture. He does not want me to advertise monomer-free dentures or relines or repairs. He uses THE cheapest acrylics, cold-cure for all procedures, Nordent and Z-Dent teeth, alginate, Type-II stone, etc. Who is correct? Do I have the right to spend the extra money and deliver a denture that fits better and last longer, and also so state? According to him I cannot educate patients on the differences in dentures. Who is correct?
Say I win, he and others will lose market share, and only then will they change how they are delivering, and this will change the market.
