FAQ

Is guided surgery more accurate than freehand?

See the downloads page for just some of the studies that analyse this but the 2015 EAO consensus was that guided surgery is more accurate than freehand, both for experienced and inexperienced dentists. Of course freehand may be accurate enough, this has to be judged for each patient.

I have been doing implants for years, isn’t guided surgery for beginners?

It’s our experience that even dentists who have placed a lot of implants place them better with a guide. Just an example, who has ever noticed that if 2 implants are placed freehand in a bounded edentulous space they seem to exhibit magnetism and migrate closer to each other than intended? The experienced implants dentists will know what we mean.

How can I afford to offer guided surgery when there is downward pressure on fees through competition?

Firstly, the cost would not be a defence against not doing the job as well as you could. Secondly, guides do not have to be very expensive and if you explain to a patient why the guide is needed (it helps to understand this yourself first) then the additional cost can be justified, much as it is, say, with GBR. Of course, if the guide offers the patient a direct advantage, like flapless surgery or being able to avoid GBR, then they will be only too happy to pay for it. You may find that people come to your practice as you offer minimally invasive treatment.

Does IRMER and ALARA mean that it is wrong to take a CBCT for all patients?

This is really a question of risk and benefit. If the patient would gain no benefit from the higher radiation doses involved in a CBCT scan, then clearly it would not be indicated. However, by definition, not all information  available in a CBCT scan is available in a 2D radiograph.

Are you able to produce guides for different implant systems?

Yes, we can merge your STL files from either an IOS or from a model scan that is sent to the lab with the DICOM file. Additional charges apply for planning. Please contact the team to discuss your exact requirements further.

Do I need a CT scan to receive a guide from IGP?

Yes, IGP only produce guides from a CT (DICOM) and STL files, we do not produce pull-down type splints as we believe these do not offer enough accuracy to be labelled as a guide for guided surgery.

Which guide should I choose?

This is determined for each individual case depending on the level of accuracy required, which planning software the clinician has available or wishes to use and which drill kit and implant system is available. As a guide please view the workflow section here.

Can I use an Intraoral scanner (IOS) to generate the STL file?

This can be used for the simple and standard guides but not the 2Ingis guide. For the 2Ingis guide due to the increased level of accuracy a conventional impression must be taken with a fiducial marker in place.
