How 3D Technology Makes Dental Implants Better

What is a Dental Implant?

Dental implants have been used predictably and successfully to replace missing teeth for decades.  An implant is considered the best way to restore a missing tooth because it most closely resembles a natural tooth.  It has a root form in the jawbone (simply called the implant or implant body), an abutment that projects out of the gums, and a crown that is built on the abutment to create a natural tooth shape.  It restores the proper look and function of a tooth without depending on the surrounding teeth for support.  Implants themselves have not changed much.  What has changed is the technology surrounding the process of dental implants and their restoration, making it more accurate and more predictable.  In order to provide the best possible result for your dental implant, Dr. Chowning uses the latest technology available in dentistry to plan and properly execute the entire implant process.

How does a 3D image make a dental implant better?

Dental implants must be completely encased in the bone of the jaws in order to function as a tooth.  A two-dimensional image (like a traditional dental x-ray) is not able to give the exact dimensions of the jawbone in a site that is proposed for placement of a dental implant.  A three-dimensional image, like the CBCT image obtained by the Galileos®, enables Dr. Chowning to measure the height, width, and length of an implant site, as well as the location of important surrounding anatomical structures.  This includes nerves, sinus cavities, and other teeth.  The importance of this pre-operative planning cannot be overstated.

How does 3D CEREC technology make a dental implant better?

Because an implant must be placed into adequate jawbone, it is common for the bone to be the only consideration made by some dentists when placing implants.  Dr. Chowning is different.  In addition to digitally planning and visualizing the correct position of an implant on a 3D x-ray, Dr. Chowning is able to integrate the final crown’s size, shape, and position into his pre-operative planning.  This creates an ideal situation where the angle and position of the implant properly absorb the chewing forces the final crown will undergo.  An implant that is placed into healthy jawbone at an improper angle relative to the final crown will have a higher risk of failure in the long run.  By planning the crown first, Dr. Chowning can design the entire implant system (implant body, abutment, and crown) for the best long-term success.

What is the process for a dental implant using 3D technology?

  1. Planning:  The first stage is planning.  Chowning will gather information about the proposed implant site, including a 3D CBCT image and a 3D intraoral scan.  These only take a few minutes for the patient.  The real work goes on behind the scenes.  Dr. Chowning will use the CEREC machine software first to design the size, shape, contours, and position of the final crown.  Then he will integrate the digital model of the crown into the CBCT software (the 3D x-ray of the underlying bone) to determine the appropriate position of the dental implant using the final crown as his guide.  The final implant position is communicated back to the CEREC machine, which makes a tool called a surgical guide.
  2. Surgery – During the implant surgery, Dr. Chowning uses the surgical guide to translate all of the digital planning into the precise and accurate placement of the dental implant. The dental implant is placed into the prescribed position in the jawbone, covered with a healing cap, and left alone to heal for several months. (The healing time is different for each patient.)
  3. Restoration – Once the implant has healed and has adhered to the jawbone, it is ready to withstand chewing forces. In a single visit similar to that of a CEREC Same-Day Crown, Dr. Chowning will design your final abutment and crown with the same principles of size, shape, contour and position used during the planning.  The three-dimensional design is then communicated to the CEREC milling machine, which creates the physical abutment and crown.  The abutment and crown are fitted to the implant and permanently secured.
