Case: Patient with IMZ Implants Wants Fixed Provision but Rejects Augmentation

Disclosure: This case was submitted by Optimum Solutions, providers of the Q-Implant Marathon. The following images show a clinical case of the lower jaw. The patient received two IMZ dental implants in region 044, 045 in 1994 which came with a partly removable bridge. In 2006 the patient wished to receive a fixed provision and strictly rejected augmentation procedures which made the application of the Q-Implant GIP implant ideal.

Generally the use of the template is sufficient for an exact determination of the implant position with a pediculated vestibular mucosa flap preparation of the operation area. The full milling is applied 1.5mm below bone level and the implant bed prepared with a 6mm hollow drill. (Fig. 1) The hollow drill milling should be carried out at low RPM (350rpm) to avoid overheating of the bone.

After implant insertion a soft silicone cap (Fig 2; Easy Cap, Trinon Titanium/Germany) is used for immediate care and the operation completed with a horizontal mattress suture. (Fig 3) Although the implants showed a high primary stability (Periotest readings between -2 and -4) immediate loading was avoided in this case. One week post surgery an irritation free emergent profile is seen (Fig.4) with X-ray images taken immediately after implantation, before prosthetics and 18 months post surgery. (Fig. 5)

sorry not interested in this kind of dentistry, if this case fails what do you tell your patient?

I would like to see some long term, independent, not manufacturer driven studies on the Q implant. I hane been doing this for a while and have seen things come and go. So show us the proof.

It’s difficult to believe that a single case (positive or negative) can persuade somebody that this or that implant brand is better or worse than the others, even if it is used for a long time.

my major objection to the case is rigid fixed prosthesis connecting posterior mandible to interforaminal mandible, ignoring the torsion flexion differential between these two segments upon heavy mastication. suspect this case will fail either restorative (fx'd porcelain/loose screws/loose cement), or funneling around implants. if i use a similar system (bicon), i do not promise immortality, and i do stress break the case or make it removable or make it out of non-rigid, resin/metal materials. if we get signs of failure, we can back up without a disaster. also would like to see a better job of ensuring keratinized gingiva on buccal of distal implant. ps: why are #1,2 maintained, altering curve of spee? also, this is a lot of force to place on old bridge above....

"Interesting" but anecdotal clinical case. Hummm, will I do this in the future ? No.

I agree with all of the above posters....I question if this is the appropriate forum for such a presentation. BTW, not that it matters, but, I would anticipate a problem in the future on the buccal aspect where there is an alveolar mucosal margin, and a minimal amount of crestal bone....and, as has been stated above, when this occurs, I would not want to be in this patient' shoes!

If you are saying this is 6 years old then looks good and deserves some interest . Of course longterm results are needed to judge properly . What sort of torque is needed to insert such an implant?

These anterior implants are threaded. IMZ implants were press-fit cylinders. IMZ Twin Plus were partially threaded. This architecture does not resemble anything I used in those years. Is there something here I am missing? RJM

Alex, I guess it's hard for some of us to buy in to the short root form concept. Like I said earlier show us the long term data. I am very interested in the Q implant. This company has what appears to be some other interesting products. Their concept of the teaching in an intense fashion is good and a confidence builder for some docs. Plus one would get to see many other cases in a short span of time.

for the record, it is up to us as implant professionals to render a fair and balanced view of augmentation vs alternative implant type so that the patient has true informed consent. over the past ten years, long narrow and short wide implants have come to the marketplace. we use them all, but we are responsible for insisting on augmentation when these alternatives are uncertain. if we recommend these treatments to our patients, and say to them the choice is equal augment or not augmented, in my experience every patient will choose not to pay us to "cut and paste" their jaws! therefore, we must recommend responsibly. i agree with long term studies, thats why we use Bicon, since they have been around since 1985. this looks like a great implant, but is certainly not a panacea, just as bicon is not.

The GIP implant reminds me of the old ' Bonefit basket implant' of the by gone days ( not so long ago!). I prefer solid Bicon over this implant. Drilling with small trephines is a fine art not suitable in the confine of the oral cavity. The vertical grooves would be the nails in the coffin for this implant. If bone loss reaches these vertical grooves, the implant is doom. This in akin to the holes in the basket implant. I am sure that some of you still removing these basket implants every now and then from patients' mouth. These vertical grooves also weaken this one-piece implant. The strong chewing force in the posterior molar region may break some of these implants. The dimension, height and angle of the abutment is fixed and do not offer flexibility in the prosthodontics reconstruction. imho, I do not think that the implant is well designed.

This is also a case for an unilateral subperiosteal implant. If a CBCT shows enough B-L space then narrow diameter root forms or a blade may be in order. Also consider the submandibular fossa. Let's keep man eye on this implant. I do remember the basket implants.

Dr Butler: I understand your logic as per the prosthetic scheme and it is correct. Actually a cement retained FPD works very nice and usually without loss of cementation, and this too is correct.

Is the osteotomy really done with single trephine? It seems as if , we are stepping back in time ,with this technique. I have smelled bone burn when trephining for autografts and unfortunately, that bone goes in the trash. I don't understand the concept. This seems to be awfully "technique sensetive"! I'm sorry, maybe I should retread the question. Bv

This patient maynot have" bought into "the bone augmentation portion of your treatment, because she may be informed enough, to know, just how hard it is, to grow vertical bone in the posterior mandible. In my opinion, it is the single most challenging aspect of reconstruction, aside from the continuity defect or recon. of the hemi maxillectomy . Bv

I think it is a great implant! Good job. With proper occlusion and perio care, it should last just fine.
