CO/CR a new alternative

2010-05-19T02:15:00.000-07:00

I have been testing the new copings from NobelProcera milled from Co/Cr block.

The results have been very good. The margins are accurate depending on how you set them and to adjust the alloy a tungsten carbide cuts it like butter, this surprised me as I thought it would be hard to adjust.

The porcelain has shown no signs of de-bonding, thermal cracking or having colour problems.

I am sure this is a viable alternative to gold based alloys which we have always used.

By scanning we also have a saving in time and costs.

Infomation Evening

2010-04-21T02:57:00.000-07:00

Thanks to all who attended the information evening last night. It was great fun for me to have your feedback and comments on the direction we are taking with NobelProcera.

Toady I scanned the co/cr copings that were asked for and we all look forward to the results.

Don't forget to use the gift certificates that you received for attending and I will add the same terms apply for the co/cr copings. This was not included initally as I wanted to make sure I could order them.

Busy, busy but next time I will look at how the co/cr copings are working.

2010-03-18T02:02:00.000-07:00

Just a follow up on the titanium crowns etc. I now have some crowns and direct to fixture abutments on Straumann rn fixtures. With the help of the referring dentist we will be following how these last. We will review every 3 months checking bone level, colour stability, occlusal wear and tissue response.

This may not be the most scientific project but will at least give an insight as to the application of titanium sub structures bonded with VM9 porcelain.

I will keep updated here.

Direct to Fixture Implants

2010-03-03T00:26:00.000-08:00

Just a simple scan and a direct to fixture Straumann bone level abutment can be created in NobelProcera to avoid using gold cylinders. This is more cost effective and the result allows for retrievability as well as a biocompatible material sub gingivally. Is this the future I think so !!!!

Titanium Crowns

2010-02-17T01:56:00.000-08:00

Is this the answer to what we have needed to produce biocompatible,consistent sub-structures for single crowns and bridges. Cost effective and fit perfectly via cad cam NobelProcera. I think this has possibilities. We are using Vita VM9 as the overlaying ceramic

Bar Continued

2010-01-19T00:32:00.000-08:00

To continue, the bar fitted perfectly and when the prosthesis was completed a solid and functional appliance was delivered to the patient. We can only marvel that now such accurate and aesthetic results can be achieved with cad cam technology. Intra-oral photos will follow.

As can be seen on the model or in the mouth the result is the same

Full Arch Removable

2009-12-30T16:05:00.001-08:00

I recently completed a removable upper on 6 implants. The case was designed using NobelGuide to position and place the implants and then the bar was designed with 3 locators in NobelProcera software. This has been the easiest and most accurate case I have done. The absence of casting and joining components, and being able to alter the bar design in real time, made me realise that nothing can compare to this way of doing a case like this. I will not do these types of cases any other way.

Convenience of Cad Cam

2009-12-07T01:38:00.001-08:00

Many patients would like knowing of the flexibility of being able to remove the crown without having a hole for direct screw access in the occlusion. Designing via cad cam will allow the cross screw to be placed in a favourable position according to the diagnostic wax up. Conventional techniques make this very difficult.

Guarantees on Implants

2009-11-23T01:43:00.000-08:00

Most implant companies will offer a guarantee on the implant if you only use their components to finish the case.The question we must ask " is this relevant in today's dentistry"

If an implant is going to fail then how does the abutment contribute to this? An interesting question with very little or no research to follow up with. One reason may well be that the abutment is structurally not compatible with the fitting surface of the implant. This can only occur if the fitting surface of the abutment is changed in any way. To logical thinking by the very nature of investing and casting this may occur. However no matter which cad cam system is employed this is taken out of the equation as files are computer generated.

Then we must address who and how can we trust be sure that the integrity of tolerances of differing implant systems will be part of a finished abutment. One would be confident with a company that is world wide producing abutments in many countries that this is not a problem. To this end I see NobelProcera as a perfect match to allow me to have confidence that I am the "designer" .So where does this leave us with the guarantee. I believe that all reputed implant manufacturers will, as many do now, construct abutments for many platforms and systems giving us the confidence to design in the lab and have produced to exacting tolerances.

Custom Astra Abutment

2009-11-21T23:04:00.001-08:00

This Astra Titanium Abutment was designed and created using NobelProcera technology. Please note that the gingival contours resemble the contour of natural gingival tissue, without casting on a gold abutment.

How Crazy is this!!!!

2009-11-21T22:38:00.000-08:00

Being able to create individual custom abutments with NobelProcera for Astra,Straumann and Nobel fixtures in titanium for at least 25% less than buying a stock gold abutment then casting onto it and modifying the design to now be an individual abutment is crazy BUT true. The end result for the patient is a more biocompatible abutment created via cad cam to the tolerances of a normal manufactured gold abutment, without the technical difficulties of casting and adjusting on a gold cylinder. To understand that I now have the design capabilities and production criteria as if I was in the design department of a major company is truly amazing.

It's now time for change

2009-11-17T00:24:00.000-08:00

I have always been frustrated that many of the popular implant systems do not allow flexibility of abutment design unless you buy a gold non oxidising abutment and then cast onto it. This technique works fine but is time consuming, costly and you still have the end result with gold sub gingivally although acceptable it is not the best material for this situation. Stock machined abutments are limited in design and do not follow gingival contours, as most have a flat horizontal contour.

I am sooooooo happy that now I can create an abutment to suit any contour and have this produced in titanium for the most popular systems in Australia. This saves time , thus money and is clinically more acceptable than gold sub gingivally.

NobelProcera now allows me to create via cad cam technology abutments for :

Astra - all platforms, Straumann - All platforms and of course Nobel- All platforms. Soon others will be introduced.

How exciting is this to be able to create a totally contoured abutment for any case and for most platforms in biocompatible titanium and at a cost effective price. ie cheaper than a stock modified abutment. i think a major step forward in technology.

Abutments continued

2009-11-10T01:32:00.000-08:00

So we get the case in do we go to the catalogue or look for another way. Cad cam will allow complete flexibility of design within the lab so both the dentist and the technician can be involved in the design. NobelProcera is the only system that will give you this flexibility. We can scan the implant position in the lab and then via screen shots or direct contact allow the abutment to be designed to the individual case by interaction between both dentist and technician. Using conventional techniques abutments are customised by casting gold onto a preformed cylinder.NobelProcera cad cam, this may I from now on call it a system will allow design to be completed in the laboratory and then the abutment milled at the controlled facility in either Japan or Sweden ( description later) this allows us to be confident that whichever design we create can be reproduced via 5 axis milling machines( again more later ) So is the world changing for the better yes with a capitol Y. I do not work for Nobelbiocare but I run a commercial laboratory that through this blog will look at the benifits of Cad Cam for both us and the clients.

back soon

Custom Abutments

2009-11-09T01:52:00.000-08:00

I don't think it is common knowledge that a custom abutment can be produced in titanium for a comparable price to a machined off the shelf abutment that needs to be modified to suit the case requirements.

A NobelProcera abutment can be created via cad cam and then produced in my region for a more competitive price than an off the shelf abutment.

To have titanium sub gingivally and then a coping which stays within the parameters of standard crown and bridge protocols is to me the most ideal situation. To many times we try to create restorations that exceed the technical parameters of the materials we have at hand

Thermal expansion of alloys and it's reaction to the bonded porcelain are always a concern

Do we need theses problems!!!!

to be continued!

Intro to Blogging

2009-11-09T01:38:00.000-08:00

Hi Bloggers,

I am a new person to blogging thanks to Nick I am now in your world. The idea of this site( if you call it that) is to expand the knowledge and applications of NobelProcera. So you may ask what's this? it is Dental Laboratory technology that will change the way we look at the lab industry and dental restorations as a whole. This blog will cover both clinical and technical knowledge

To let you know I run a commercial dental laboratory in Melbourne, Australia and have been involved in the Procera technology since it's introduction to Australasia yes that does include NZ!!!

So where to from here. If this does not interest you then may I bid you goodbye, if this is of interest then I would be more than happy for you to join me in meaning full discussion on the future of the dental cad cam industry.

If this has tickled your taste buds give me a reply. I will be back soon with some meaningful discussion

Cheers

Rob Hill
