Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

When you hear the word “surgery,” your first thought might be of a high-charged operating room with a surgeon operating intently as a nurse mops sweat from their brow. While there are high-stakes surgeries, most aren’t quite that dramatic.
Dental implant surgery falls into the latter category. It does qualify as a surgical procedure because we make incisions and tissue alterations for the implant. But it’s no more rigorous than a surgical tooth extraction.
Still, if you’re new to implant surgery, it’s natural to feel some apprehension about it. To calm any nervousness, here’s a rundown of what to expect before, during and after the procedure.
Pre-Planning. Implant surgery is usually a routine affair because of meticulous planning beforehand. Often, we map out the implant site using CT scanners or other high-level imaging, identifying obstacles like nerves, blood vessels and sinus cavities, verifying there’s enough bone present to support an implant. With this information we can create a surgical plan or guide for placement in the mouth to accurately situate the implant.
Site Prep. On the day of the surgery we’ll first administer local anesthesia to numb the entire work area to pain. We’ll start with a few small gum incisions to expose the bone. Then using the surgical plan or guide, we’ll create a small channel for the implant with a drilling sequence that successively enlarges it until we achieve the best fit for the implant.
Implant Placement. Once we’ve completed drilling the channel, we’ll remove the implant from its sterile packaging and install it in the channel. After we’ve made any necessary adjustments and verified proper placement with x-rays, we’ll suture the gum tissue back into place.
After the Surgery. You might experience mild to moderate discomfort afterward that’s usually manageable with over-the-counter pain relievers like ibuprofen or acetaminophen. We can, if necessary, prescribe medication if you require something stronger. We may also prescribe an anti-bacterial mouth rinse for a short time to reduce the risk of infection.
After the implant has integrated with the bone which usually takes about 8-12 weeks, we’ll install your life-like crown or restoration. Your new smile and improved dental function will be well worth the process.

Complete tooth loss is a common condition among older adults, gradually occurring one or two teeth at a time. There often comes a point of realization, though, that all the teeth will eventually be lost.
This can create a dilemma: Do you replace teeth as they're lost, or go ahead and have all of them removed at one time?
Up until recently, the latter choice seemed the most practical and affordable. But most dentists would agree that keeping natural teeth for as long as practical is better for a person's overall oral health and to slow any potential bone loss.
The emergence of dental implants has made this less of a dilemma: We can use this technology to more affordably replace teeth in stages rather than all at once. This is because an implant is technically a root replacement: a dentist inserts a titanium metal post into the jawbone. Because of an affinity with titanium, bone cells grow and adhere to the implant surface, which creates a stronger hold. It also impedes bone loss.
We can, of course, use implants as individual tooth replacements. But the expense of this approach with multiple teeth puts it well out of reach financially for many people. But implants can also be used as connective points between the patient's jaw and other kinds of dental restorations like bridges, partial dentures, and full removable or fixed dentures.
Using this approach, we can adopt a strategy of allowing healthier teeth to remain until it's necessary to remove them. We initially place implants to support a bridge, for example; later we can use the same implants along with additional ones to support a larger restoration, even a fixed full denture.
An implant-supported restoration is typically more expensive than traditional bridges or dentures, but far less than replacing teeth with individual implants. And because the stages of restorations may occur over a long period of time, the cost can be spread out to make it more manageable.
If you're facing a future where it's likely you'll lose all your teeth, you don't have to lose them all at once. Staged restorations with implants could help you hold on to your natural teeth for as long as possible, slow bone loss and make for a healthier mouth.
