Zygoma Implants to Retain Removable Partial Denture?

Zygoma implants are not for the faint at heart. I have done a couple but I am not an expert my any strench on zygoma implants. Dr. Tom Balshi is an expert, he has done many. There are a couple of nice articles on Zygoma implants. One articlew in JIACD - Journal of Implant and Advanced Clinical Dentistry in the April edition which can be viewed online. And One article in the ICOI Journal- Implant Dentistry in the May issue I believe which can be accessed online. Read up on it, it is a nice option to offer a patient with no bone.

Which way has a higher success rate? sinus graft or zygomatic implant?

I've been placing zygoma implants since 1991 initially in Sweden only, and in the U.S. since 1997. This case, as you've outlined, is NOT an indication for the use of the zygoma as anchorage.

Oh, and by the way, the zygoma implants have a higher success rate than sinus grafting.

To Ed S- Just wondering where your statement comes from regarding success rates with sinus grafting vs. zygoma fixtures. Is this in your hands, or a published study. No disrespect, but as someone who does both routinely, I'm always looking for info. I think one thing that we need to remember is the challenge that these compromised cases present to us. So "success rates" in my mind always need verification. Additionally, are you using CT planned surgery, and if so, what software. Thanks

International Journal of Oral & Maxillofacial Implants... The Academy of Osseointegration's official journal... publications of multi-center prospective study. I'm one of the centers and have had 100% success rate of osseointegration and none lost under prosthetic load of over 100 Zygoma fixtures, with personal U.S. follow-up now to 12 year mark. Multi-center results are only marginally less successful.

Sorry. Forgot to add... I have not found any currently available commercial planning software which is ideal for Zygoma fixture planning surgery, but Nobel is currently developing software in Europe which will aid in planning even hemi-facial reconstructive cases.

I have more than 13 years of very good experience with the combination of teeth and implants as "strategic" abutments in cases of partially edentulous patients who needed a RPD. (you can find my articles on this topic on the Pub-med). I never used a zygomatic implant in those cases but I think that it is possible, just have to find a skilled surgeon to do this. If you have 2 implants at the posterior right, try to find place for at least one implant even at the PM zone and it will work fine. During the last years I use the Locator attachment. The major connector design can be a single broad palatal one and take in consideration to place (if you can)minor connectors in contact with vertical teeth surfaces in order to stabiize the RPD. Sorry for the long comment..

We've used iDent software to plan a zygoma case with a CBCT. It really pushed the limits of the software, but it worked!

My Dear, Why dont you plan to have an mini implant in the system as with mini impants you don need to bother much region of placement. Think over it . Comments Invited.

I agree with the concern but in my opinion zygoma implants would be a more expensive solution can we not think of a angled abutment like a pallomalo technique well I am also looking for a answer my comments are to just push the discussion.

Well i partly agree with the Dr Tushar but the discussion started with the faliure of the implants so with out the CXT test there are every chances of failure of Placement of another implant in the area.

hi the zygomas are basically designed for a fixed option and hence will be supported by a procera implant bridge framework or with a abutment level framework but not a over denture retention attachments. in other words you will not find components to do an attachment regards

also the rigidity for a zygoma is not much as it is stabilised at the zygomatic level and the length makes it vulnerable to fractures. only if is splinted it gains rigidity.

friends i have a doubt i want to know how to place the prosthesis on zygoma implant since the head is angulated
