Imagine this: An implant surgeon is performing a thorough examination of your mouth. The surgeon rotates your jaw from side to side and up and down, looking for the optimal sites in which to place dental implants — and the proper size, shape and orientation for the implants to have. He or she may test several alternatives, considering the underlying anatomical structures, and the bone density and quality that the examination reveals. Finally, a surgical plan is developed: This includes a set of precise specifications for implant position, size and depth, and a template for creating a perfectly fitting set of replacement teeth. But no invasive procedures of any type have been performed so far. In fact, you aren't even present.

Welcome to the world of computer-guided dental implant surgery. What we have described is one step in the process that allows you to receive a set of replacement teeth with the minimum amount of surgery (and time spent in the dental chair), and the maximum level of preplanning foresight. It can result in faster overall treatment time, less discomfort, and an outcome that pleases everyone. Let's look a little more closely at the entire process of computer-guided implant surgery — a procedure at the forefront of dental implant technology.

The First Phase: Making A Virtual Model

It all begins with a complete examination and modeling of your existing teeth, gum and jaw structures. In many cases, a physical impression (replica) of the jaws is made, which will aid in planning the location of the new teeth. But the modeling doesn't stop there: A high-tech, three-dimensional CT (computed tomography) scan is also performed. This allows us to examine the structures (including bone, nerve tissue and sinus cavities) which lieinside the jaw. It is often accomplished using “cone-beam” CT technology, in which the scanning device quickly captures a complete digital image of internal structures as it rotates around your head.

The next step of the process relies on powerful computers and sophisticated software to take the raw CT scan data and translate it into a 3-D model of the jaw. This virtual model can be manipulated on a computer screen — rotated, measured, even “operated” on — so that we can visualize the placement of dental implants and determine their optimum position with a high degree of accuracy. Using this technology, it's now possible for us to evaluate anatomical structures virtually — structures it once would have taken surgery to reveal — and to plan out the implant procedure accordingly.

The 3-D model we have developed is then used for two purposes: to create a precise guide for the implant surgery, and to allow the dental laboratory to pre-manufacture a set of replacement teeth that will fit precisely in the jaw. An advanced set of CAD/CAM (computer aided design/manufacture) processes is used to generate the physical objects — in this case, the surgical guide and the prosthetic teeth. Depending on your individual situation, the new teeth may be attached the same day as implant surgery, or after a healing period of 6 to 12 weeks. In either case, our precision modeling ensures that they will fit perfectly with the implants and the jaw.

Implant Surgery: Following the Plan

The implant surgery itself is typically performed under local anesthesia, and often requires no sutures (stitches). In the surgical procedure, the template we have produced (which resembles a nightguard or athletic mouthguard) is securely (but temporarily) fixed in position on the jaw. The openings in this template form precise guides for the placement of the implants — accurate in terms of position, width and depth. In fact, the implants fit so perfectly into these prepared sites that we can have new teeth placed the same day as implant surgery.

Since so many of the details have been accomplished in the planning stages, computer-guided implant surgery is typically uneventful for the patient. It can result in shorter time in the chair, less discomfort during recovery — and a highly pleasing result. It has even been called the most significant innovation in implant technology since osseointegration — the fundamental process by which a dental implant becomes fused with the bone.

Full or partial tooth loss, if left untreated, doesn't just affect a person's self-image — it can also increase the risk of developing nutritional problems and other systemic health disorders. Fortunately, there's a reliable and time-tested method for treating this condition: full or partial dentures.

Dentures are just one option for replacing missing teeth; some of the others include fixed bridgework and dental implants. Each method has its particular pluses and minuses, which should be carefully considered. There are also several varieties of dentures available to address specific issues, from partial dentures to implant-supported overdentures. The best option for you will depend on your individual situation.

How Do Removable Dentures Work?

Full or partial dentures consist of a gum-colored base made of plastic resin, which fits over the remaining alveolar (bone) ridge that formerly held the teeth. The prosthetic teeth projecting from the base are designed to look and function just like your natural teeth. Dentures are held in place primarily by the suctioning effect of their close fit against the alveolar ridges — that's why it's so important that they are fitted properly. The upper denture also gets extra support from the large surface area of the roof of the mouth (palate), which generally makes it extremely stable.

At first, wearing dentures may require some getting used to in terms of talking and eating, as the dentures become “balanced” in the space formerly occupied by the teeth. But over time, the muscles, nerves and ligaments of the mouth learn to work in new ways, which allows these functions to occur normally. Dentures also help support the facial skeleton and the soft tissues of the lips and cheeks, which can help create a more youthful appearance.

Types of Full Dentures

Removable denture types.Immediate Dentures: These are usually a temporary means of helping you transition to successful denture wearing. Because of the muscular readjustment required, as well as the natural shrinkage of gums, the dentures which are placed immediately after tooth extraction won't fit as well as permanent dentures made when the healing is complete. They do, however, provide you with new teeth right away, and give you time to adjust.

Conventional Full Dentures: After a period of time, permanent dentures that conform to your mouth with near-perfect accuracy can be fabricated. These are carefully crafted to look as much like your own natural teeth as possible, and are able to function properly in your mouth for a long time.

Implant-Supported Overdentures: To increase the stability of a lower or upper denture, it's possible for it to be securely anchored using two or more dental implants. The upper jaw requires more implants (generally three or more) than the lower jaw due to a lesser bone density. Many people find this option offers a great balance of comfort, functionality and value.

Types of Partial Dentures

Transitional Partial Dentures: These relatively inexpensive removable plastic dentures serve as a temporary tooth replacement and space maintainer as you wait for your mouth to heal from tooth extraction, for example. Once the healing process is complete, dental implants can be placed.

Removable Partial Dentures (RPDs): Usually made of cast vitallium, these well-constructed, metal-based removable partial dentures are much lighter and less obtrusive than those made of plastic. They are a little more expensive than plastic dentures but will fit better. They are, however, much less expensive than implants or fixed bridgework.

How Dentures Are Made and Fitted

Lab making denture.Making quality dentures is a blend of science and art. First, an accurate impression (mold) is made of the alveolar ridges on the top and bottom of your mouth. The base of the denture is made from this mold in a dental laboratory. Working together, the dentist and lab technician choose from among many different sizes and shapes of prosthetic teeth to re-create a natural-looking smile. When everyone is satisfied with the result, the temporary dentures are made in permanent form.

To enable normal speech and eating, it's crucial to balance your bite. This means that the upper and lower dentures come together and properly stabilize each other. The form and function of the dentures are carefully checked to ensure that they are working and fitting properly.

What to Expect After You Get Dentures

If you've recently lost your teeth and received an immediate denture, it's normal to find some tissue shrinkage and bone loss occurring. Therefore, in several months you may find that your immediate dentures no longer fit well. You will have two choices at this point: You can have your immediate (temporary) dentures re-lined. This means that material is added under the denture's base to better conform to the new contours of your alveolar ridge. A better option is to move to a set of conventional full dentures, which will last longer and fit better. With proper care, dentures offer a functional, aesthetic and economical solution to the problem of tooth loss.
