Guided Implants: A New Standard for Safe and Precise Dental Treatment

Dr. McNeel has been using NobelGuide for the computerized placement of dental implants since 2005.   This approach allows Dr. McNeel to literally place dental implants without making a surgical cut and, therefore, requires no stitches.  It is truly minimally invasive.   

The underlying interests of most doctors embracing CT Guided Dental Implants is primarily to provide a degree of treatment accuracy that has never been  possible.

Most radiographic images that are used today for determining where to place implants are two dimensional. By combining multiple xrays of a particular implant site, a reasonable estimate of bone height can be obtained.

In many cases, however, absolute bone quality is not determined until the bone is exposed during surgery. This often leads to surprises for the implant surgeon. Taking the gamble of placing an implant device into bone of marginally inadequate width may result in failure or
a restoration that cannot be completed properly.

CT Scan technology (an existing standard in the field of medicine), and more recently, new Cone Beam types of scanning devices have been developed that provide levels of accuracy and precision data collection that enable digital mapping and Virtual Treatment Planning.

Doctors who place dental implants can readily visualize "slices" of jawbone anatomy, from several perspectives, and create treatment plan choices that take the best advantage of jawbone structure and integrity so the guesswork of where, which dental implant device, and how to firmly place an implant is virtually eliminated.

Unique drilling guides are developed for an individual treatment and are based on the technical data derived from the virtual assessments. A dental implant guide can be developed for a single tooth... all the way to an entire set of new teeth, for edentulous patients.

SimPlant and NobelGuide offer a variety of implant guide configurations that enable the guided implant dentist to provide choices of the best implant success outcome for practically any tooth or teeth replacement need.

Freehand implants, a currently accepted and readily practiced method of implant placement, is avoided.

High Resolution Imagery: Foundation for Virtual Surgery

Dental practices that have the full complement of technologies for Virtual Treatment Planning and the creation of Implant Guides (SurgiGuides and NobelGuide) are able to assess, diagnose, and develop treatment plans that incorporate the best advantages of dental implants, especially important for certain patient population groups.

Patients who are at risk for having "bone integrity complication issues" may include:

  • Patients who have had numerous untreated extractions
  • Previous denture wearers
  • Patients needing anchored dentures
  • Candidates for fixed bridges
  • Replacement of failed implants
  • Alternative treatment for failed bone grafts
  • Patients seeking to avoid bone graft surgery
  • Patients who have completed severe gum disease treatments
  • Trauma victims
  • Congenital jawbone defects
  • Aging patients needing renewal or replacement of worn out restorations
  • Other compromised bone or resorption issues

The Implant Surgery Event

The entire process of assessment, treatment planning, selection of implant devices, and final restoration products is achieved "virtually" before treatment even begins.

Implant patients typically accompany the doctor in reviewing digital representations of their treatment needs. This may include any number of computerized digital images that reflect the shape, density, and other characteristics of their jawbone structures.

Patients will determine, with the guidance of the implant surgeon, their best treatment choice for creating the best possible tooth replacement infrastructure. Next, the cosmetic and aesthetic phase is completed, where the final restoration products are selected, based on their choice of types of crowns, abutments, shape, color shading, size, etc.

The technical data is used to fabricate the implant guide(s) and attachment devices, if needed, that are instrumental for treatment.

The actual process of undergoing surgery is comparatively short, since all planning has been completed. Having 4-5-6 implants placed in less than 30 minutes is not unheard of. Understandably, this particular feature of having guided implants is very appealing for most patients.

Need for anesthesia is short ... as is the need for having the jaws kept open for an extended period of time. Post treatment pain or muscular discomfort issues may be non-existent for many patients.

In order to better control the late discovery of inadequate bone structures, cross sectional images are required. They are now quickly becoming the standard level of care. There are only two ways to acquire these images.

The first method uses Tomography. The amount of radiation is mild compared to a CT scan. Tomograms result in a 60-70 magnification and are accurate about 60 percent of the time.

The second technique involves the use of Computed Tomography Studies (CT Scans). This allows a very detailed assessment in three dimensions.

Picture Computer Assisted Guided Implant Surgery These 3-D visualizations coupled with the appropriate software allow implants to be placed with a level of precision that was unattainable several years ago. In addition, the surgical procedures can often be accomplished in a much more conservative procedure which involves greatly reduced discomfort, less treatment time and a more accurate final outcome.
