If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

Here's some good news: Teenagers are less likely than adults to lose teeth to dental disease. But there's also a flip side. Teens can still lose teeth, more likely from traumatic injury.
Fortunately, there are several options for replacing lost teeth like dentures or bridges. But the choice considered best by most dentists and patients is a dental implant. An implant tooth looks and functions like the real thing—and it's durable, capable of lasting for years, if not decades.
But there's a hitch with teens getting an implant: Even though they may have all their permanent teeth by adolescence, their jaws are still growing and developing. Natural teeth, with their attachment to the jaws by way of a periodontal ligament, can keep pace with this growth—but implants can't.
That's because an implant doesn't have this attachment to gum tissue like natural teeth, but to the jawbone alone. Hence, an implant tooth can't keep up with jaw development, and may eventually look like it's "sunk" into the gums in relation to the teeth around it.
It's best, then, to wait until a teen's jaws have fully developed before attempting an implant. In the meantime, though, they don't have to endure a smile marred by missing teeth, but can replace them with a temporary restoration. The two most common options are a partial denture or a modified bridge.
The partial denture is a lightweight version that's quite affordable. Although not as durable as other types of dentures, the appliance is only intended to last until the patient is old enough for a permanent implant.
The modified bridge is a prosthetic tooth with strips of dental material extending behind it that are bonded to the backs of the teeth on either side to hold it in place. It's likewise not as durable as a traditional bridge, but it can fill the bill until time to place an implant.
Although this adds an additional step in a teen's restorative journey after losing a tooth, it's necessary—waiting to place an implant after jaw maturity will help ensure a long-lasting result. In the meantime, a temporary tooth replacement will help them to enjoy a normal smile.

Your teeth can take decades of daily biting and chewing and not miss a beat. But they do have a nemesis, dental disease, which can easily get the upper hand. As a result, millions of people lose teeth each year to tooth decay and periodontal (gum) disease.
But while both the living tissue that makes up teeth and gums are susceptible to bacterial attack, the non-living materials in a life-like dental implant are impervious to disease. That being the case, you would think your implants wouldn't need as much hygiene as your other teeth.
But they still do. True, implants in themselves aren't affected by infection, but the bone and other tissues that support them can become diseased. This often happens with advanced cases of gum disease.
There is, in fact, a particular form of gum infection associated with implants called peri-implantitis ("peri"—around; "it is"—inflammation), which occurs in the gums around an implant. Once it starts, peri-implantitis can advance at a rapid pace.
This is because implants don't have the gum attachment of real teeth, which can fight and slow the advance of a gum infection. Because an implant doesn't have this attachment, any infection around it continues virtually unimpeded. If the bone supporting an implant becomes infected, it can weaken to the point that the implant fails.
But this dire scenario can be avoided with continuing hygiene and maintenance of the gum tissues surrounding the implant. You should brush and floss every day around implants to remove dental plaque, the bacterial film most responsible for dental disease, just as you do with natural teeth.
It's also important to keep up regular dental visits for cleanings to remove lingering plaque and tartar (hardened plaque). Your dentist may also notice and clean away any residual cement from the restoration, which can also cause gum inflammation.
And, you should promptly see your dentist if you notice any telltale signs of a gum infection, such as swelling, redness or bleeding, especially around implants. The quicker we diagnose and treat a case of gum disease, particularly peri-implantitis, the less likely it will endanger your implant.
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.

Unlike the natural tooth it replaces, a dental implant is impervious to decay. But don’t think that means you can relax your oral hygiene habits — even though the implant itself can’t be infected, the surrounding gum tissues and bone can. And if they’re not properly cared for you might eventually lose the implant.
In fact, implants may be more susceptible to problems from impacted food that becomes wedged between the gums and teeth than their natural counterparts. Natural teeth are connected to the jaw by way of a resilient, elastic tissue known as the periodontal ligament: the ligament resides in the space between the tooth root and the bone and attaches to both through tiny fibers. The bone and ligament are protected by an attachment of gum tissue that covers all of the surrounding bone and attaches to the root surface. The outer gum tissue surface is covered by a protein called keratin that makes it resistant to wear.
On the other hand, these periodontal ligament fibers don’t exist when implants are present as the implant is fastened directly to the bone. Because it doesn’t have this ligament attachment, and the gum tissues around can’t attach to the implant as with natural teeth, it may be more vulnerable to bacteria or trauma caused by food impaction. So, cleaning and caring for dental implants is just as important, if not more so than with natural teeth.
If the gums around an implant become infected and inflamed it could lead to peri-implantitis, a condition that can destroy the bone attachment between the implant and the bone. In other words, the loss of bone support can weaken the integration of the implant with the bone. As more and more attachment is lost, the implant can loosen and eventually be lost.
The best way to avoid this is with consistent daily hygiene and regular dental checkups. And, if you notice any signs of swelling or redness of the gums around an implant, contact us as soon as possible. The sooner we begin treatment to alleviate the infection, the less danger there will be of losing your implant.
