When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.
Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.
But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.
CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.
Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.
Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.
Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.

Teenagers can have the same smile-disrupting tooth flaws as adults. But not all cosmetic treatments available to adults are appropriate for teenagers—at least not until they get a little older. Dental veneers fall into that category.
A veneer is a thin porcelain shell custom-made by a dental lab, and bonded by a dentist to the face of a tooth to mask chips, stains, gaps or other imperfections. Because they're less invasive than other measures, veneers are highly popular as a cosmetic dental solution. They do, however, usually require some enamel removal so that they'll appear more natural.
This enamel removal typically won't impact an adult tooth other than it permanently requires it to have veneers or other restorations after alteration. But there is a risk of damage to a teenager's tooth, which hasn't fully developed.
Adolescent teeth usually have a larger pulp chamber (filled with an intricate network of nerves and blood vessels) than adult teeth. And because the enamel and dentin layers may not yet be fully developed, the pulp is much nearer to the tooth's surface.
We must be very careful then in removing enamel and dentin for veneers or we may penetrate the pulp and risk damaging it. Alternatively, there is the possibility of no-prep veneers which are very conservative but often are unable to be done because of the need to often remove tooth structure to make the veneers look natural.
Another cosmetic problem can occur if we place veneers on a patient's teeth whose jaws and mouth structures are still growing. Eventually, the gums could recede and an unsightly gap form between the veneer and the adjacent natural tooth.
Fortunately, there are other techniques we can use to improve a tooth's appearance. Mild chipping can be repaired by bonding composite resin material to the tooth. Some forms of staining may be overcome with teeth whitening. These and other methods can address a teenager's smile appearance until their teeth are mature enough for veneers.
Whether or not a tooth is ready for veneers will depend on its level of development, something that can often be ascertained with x-rays or other diagnostic methods. And if a tooth has already undergone a root canal treatment, there isn't as much concern. In the meantime, though, it may be better for your teen to wait on veneers and try other techniques to enhance their smile.

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.
