CT Scan for Dental Implants

Print This Post

Dr. Scott Ganz believes that “those practices where a relatively high volume of implants, will soon witness the appearance of CT machines…”. Furthermore, “One of the problems I see is that there are many formulas or cook-book approaches to treatment planning for implants. You know, like so many implants are required to replace so many teeth or how many implants are necessary to support a particular kind of prosthesis.” Read more of his thoughts on CT Scans for dental implants by clicking here for Part I or clicking here for Part II.

  I have been using CT scans and stents for virtually every implant I have placed since about 1995. I think the key reason why surgeons do not see the value in CT scans in placing implants is the problem with transferring the data they see on the CT scan to the mouth in an accurate manner. Angulations and position of placement can be estimated with software but transferring that data to the mouth accurately is still done by an estimate. I was glad to finally see the ability to correlate a stent to the CT scan commercially at the SF Osseointegration convention. I have been using CT scans and Stents with “tube” markers since about 1995 and was using stents with “guide tubes” since 1993 to accurately place implants in 3 dimensions while also controlling depths. I would not place an implant without them. They not only allow accurate implant placement in 3 dimensions but also allows pre-planning of abutments, restorations and aesthetics. They also allow placement of the longest implants possible in a given situation by allowing closer placement tolerances to critical structures (ie. nerves, the sinus and adjacent roots. I believe this greately improves success rates from a restorative as well as surgical point of view.

  Great comments. Glad to hear that you believe that CT imaging “improves success rates from a restorative as well as surgical point of view.” Without 3D imaging we are still guessing… and I agree that most Oral Surgeons seem the reluctant to use CT for the reasons you state, and also because they were never trained with interative CT based treatment planning concepts. The AO Meeting in SF was where Michael Klein introduced the “missing link” the connection between the CT imaging data created with the “plan” and the surgical template. As Chairperson for Technology Day, I tried to focus the day on this technology, but at that time the interest just was not there, and the day was cancelled. I am happy to see the industry moving in the right direction now. Glad to hear that you are a long time convert!

  I believe that the use of a CT is very important, I send most patients for a CT to a facility that specializes in the procedure. I would not own a CT in my facility for liability purposes and have all images read by a oral radiologist. The CT is of benefit but the liability of owning a CT is of no interest to me. really think, even though the price is affordable for the scanner is it really worth it? Who do the CT companies suggest should take the CT, read the CT? who do the courts believe should take the CT read the CT? Could you read the CT for a blockage in the carotids? hope so, it is imaged when you scan!

  I purchased recently a dental CT scanner (Prexion). I am a general dentist and am looking for some help on Informed Consent forms for GP dental offices. My primary reason to purchase a CT scanner is for Implant treatment planning, how do I cover my liability for other associated areas? Is there a ADA approved form? Thanks in advance
