Dental implant FAQs
What is Guided Surgery?
Guided surgery is a procedure which initially involves a Diagnostic CT Scan to accurately evaluate the oral condition of the patient, it is then used to produce a Radiological Template. A further scan will then be taken with the Template in place in the patients’ mouth. The digital information provided by the scan will then be sent to a specialist laboratory where a Surgical Drilling Guide will be manufactured.
This Guide will be placed in the patients’ mouth during surgery and will provide an in incredibly high level of accuracy when placing the dental implants; especially in the case of multiple implants and implants for retained dentures or multiple bridgework.
This highly accurate method of implant placement eliminates virtually all possible risk by predetermining the optimum position and exact depth and angle of the implant.
Why Would I Need Guided Surgery?
In the case if single dental implants guided surgery would probably not be necessary. However, if you need to have numerous implants or implants for one or more dental bridges or implant retained overdentures it is usually the preferred method. CT scans are used because they can accurately indicate bone loss and proximity to low sinus cavities and nerve canals; panoramic x-rays can also be used for this purpose but the level of detail displayed is limited as compared with CT scans.
Without the use of a CT scan it is not possible to accurately make an assessment. The Panoramic X-Ray method can on occasions cause the need for expensive procedures such as bone grafts and sinus lifts which can often be avoided with the use of CT scans and Surgical Drilling Guides.
Furthermore, the advantages of the CT scan & guided surgery implant method, can in some cases allow patients who may not have been able to have implant treatment, due to an inaccurate diagnosis using the panoramic x-ray method.
Is Guided Surgery Expensive?
Guided surgery is not expensive in comparison to the potential cost of sinus lifts or bone restoration procedures. Furthermore, it significantly reduces the risk of a dental implant being rejected due to an inaccurate insertion, as compared to an accurately placed implant lasting over 15 years.
When the guided surgery method is used for several implants, it is very cost effective, partly due to reducing the necessary time spent at the clinic; and as previously mentioned it is a far a safer method.
How Does Guided Surgery Assist In Implant Placement?
Guided dental surgery based on three dimensional scans, new biomaterials, and what dentists call immediate ‘loading’ of the crown on a dental implant.
Guided Dental Surgery incorporates the latest technologies in dental implants including new and innovative biomaterials, CBCT scans to facilitate a complete implant procedure being completed in a single day.
By modifying the surface if the implant to make it porous the rate of fixation to the bone is enhanced. This is achieved by treating the surface if the implant in an acid bath and then passing an anodic electronic charge through it.
