What was the ratio for investment expansion? Special investment or what you normally use?
Are you in the States?

Hi, investment is quadvest, same ratio as x e.max and units were a little " tight". Next one I will increase liquid %. I think any investment for pressable will work. For now I'm still testing. I have some larger cases to do but I need some more time. So far all good. I will post more stuff soon.
I'm in Australia btw.

A lot of folks are switching from PEEK to PEKKTON because its more user friendly. The Canadians now have it (Swiss N Metal),and its here in the USA as well (Anaxdent),should be released (FDA approved) in the next month. :)

Actually Bredent's is not PEEK . It is enhanced PEEK . The raw material is PEEK , and they also added ceramic in it . That is why they call it BioHPP . I have done a few cases , all-on-4 included . IMO , those HPP (High Performance Polymers) , such as BioHPP , Juvora PEEK , C&M Pekkton , are the future for implant cases .

This is the all on 4

Yes you can. This was my first one which I cemented but you can press directly to Ti ( you may need some retentions and sandblasting I guess). I don't have a protocol in place yet, I'm following some groups on FB. Not much help here in Australia.

Hi Drizzt, this is exactly why I got interested in Peek ( pekkton etc.). After seeing some really beautiful work on FB ( like this one). I have one sitting on my bench waiting to be pressed, just need few more try with the stuff. I will post some pictures ( if successful :) ).

Fair question, many implant company use peek as healing abutment which is a testimony to pekk's good tissue response. Material is very compact and dense (no porosity) and can be polished really well.

Jason , they claim that it behaves better than anything . And I don't have reason not believe them .

It doesn't react with anything in the oral enviroment and it is 100% biocompatible . Juvora is using it for more than 10 years , over 10.000 cases I think are already placed in the mouth and work . In any case , the whole philosophy of the material is really great for implant cases .

I haven't pressed any , I only mill it since I have the mill . Two friends of mine , Phil Redington and Lee Mullins from Leeds , UK , are experts on HPP , and they are doing amazing things with them ! If you follow them , then you should hget one or two usefull tips for pressing it . The Bredent sprue technique works greatly . Lee is pressing a Piku-plast copy if the wax up .

. The FB groups are great, lots of pictures and lot to learn from. I'm sure your work is on there as well , good stuff. What is your protocol for bondig: alox and visiolink? I found a study that claims 1 min in 98%
sulfuric acid gives the best bonding value.
