DentalImplantsBetterthanEverthankstoOngoingTechAdvances

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.

Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.

But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.

These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.

Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.

These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

IssuestoConsiderBeforeDentalImplants

With their durability, versatility and life-likeness, there’s no doubt dental implants have revolutionized teeth replacement. If you’re considering dental implants, however, there are some issues that could impact how and when you receive implants, or if you should consider another type of restoration.

Cost. Dental implants are initially more expensive than other tooth restorations, especially for multiple tooth replacement. However, be sure you consider the projected cost over the long-term, not just installation costs. Because of their durability, implants can last decades with little maintenance cost. In the long run, you may actually pay more for dental care with other types of restorations.

Bone health. Dental implants depend on a certain amount of bone to properly situate them for the best crown placement. If you’ve experienced extensive bone loss, however, there may not be enough to support the implant. This can often be overcome with grafting — immediately after extraction, at the time of implantation or a few months before implantation — to encourage bone growth. In some cases, though, bone loss may be so extensive you may need to consider an alternative restoration.

Gum Health. While implants themselves are impervious to infection, they’re supported by gum and bone tissues that can be affected. Infected tissues around an implant could eventually detach and lead to implant failure. If you have periodontal (gum) disease, we must first bring it under control and render your gums infection-free before installing implants. It’s also important to maintain effective oral hygiene and regular dental cleanings and checkups for optimum implant health.

Complications from osteoporosis. People with osteoporosis — in which the bones lose bone density and are more prone to fracture — are often treated with drugs known as bisphosphonates. In less than 1% of cases of long-term use, a patient may develop osteonecrosis in which the bone in the jaw may lose its vitality and die. As with bone loss, this condition could make implant placement difficult or impractical. Most dentists recommend stopping treatment of bisphosphonates for about three months before implant surgery.

If you have any of these issues or other complications with your oral health, be sure to discuss those with us before considering dental implants. With proper planning and care, most of these difficulties can be overcome for a successful outcome.

If you would like more information on pre-existing conditions that may affect implants, please contact us or schedule an appointment for a consultation.

TeenagersMayNeedaTemporaryToothReplacement

Losing a tooth affects not only your smile but your overall dental health too. A dental implant solves both issues: it replaces the whole tooth, including the root, to merge durability with a life-like appearance.

For teenagers with a missing tooth, however, an implant may not be a good idea, at least until they've physically matured. Although their permanent teeth have usually all come in by puberty, the jaws and facial structure continue to develop into early adulthood. An implant placed too early could appear misaligned when the jaw fully matures.

The best approach for teens is a temporary replacement until they're physically ready for an implant. There are two good options: a removable partial denture (RPD) or a fixed bonded bridge.

Common among adults, an RPD is also a viable replacement for a teenager's missing tooth. An RPD consists of a prosthetic (false) tooth set in a nylon or acrylic base that resembles gum tissue. Metal clips formed in the RPD fit over adjacent teeth to hold the appliance in place; this also makes it easy to remove for cleaning or sleep time. We typically recommend an acrylic base for teens because it's easier to adjust if the RPD's fit becomes loose.

To hold it in place, a traditional bridge uses crowns on either side of the replacement tooth to bond over the natural teeth next to the open socket. Because this requires permanently altering the support teeth, we recommend a bonded bridge that doesn't.

This modified bridge uses wing-like strips of dental material on the back of the false tooth that project outward. With the tooth in place, we bond the extending portions of these projections to the back of the adjacent teeth, which secures the false tooth in place.

Of the two options, the bonded bridge is more comfortable, buys the most time and looks the most natural. But it will cost more than an RPD. Bite issues, teeth grinding, overall gum health or your child's level of hygiene conscientiousness could also nix it as a viable option.

Either choice will effectively replace your child's missing tooth until it's time for a permanent restoration. We'll help you weigh all the factors to determine which one is best for your situation.

CharlizeTheronBackinActionAfterDentalSurgery

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.

"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."

Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!

“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”

Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.

Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.

Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.

Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.

If you have questions about bone grafting or dental implants, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Immediate Dental Implant.”

ImplantscanSupportaTotalToothReplacementRestoration

You may be familiar with a dental implant used to replace a single tooth — but implant technology can do much more. Implants can also support other restorations including total teeth replacement on a jaw.

The reason they're so versatile is because implants replace the tooth root as well as the visible crown. We use a metal post, usually made of titanium, which we surgically implant in the jawbone as a root substitute. Because of a special affinity with titanium, bone around the implant grows and adheres to it and creates a durable bond.

With a single tooth replacement (the implant's original purpose when they were introduced in the 1980s) we attach a life-like porcelain crown to the individual titanium post. But with their continuing development we've adapted implants for other applications, like using a few strategically-placed implants as a stable platform for removable dentures or fixed bridges.

We're now able to use implants to support a full prosthetic (false) dental arch. Though similar in appearance to a removable denture, this particular prosthesis is permanently joined to the supporting implants with retaining screws.

Of course, the application requires careful pre-planning, which includes making sure you have enough healthy bone to support the implants. We'll also need to determine how many implants you'll need (usually four to six for this application) and create a surgical guide to place them in the best location for supporting the prosthesis. A dental technician will then create the prosthesis to match your jaw ridge contours and facial structure.

Using implants this way has a benefit other types of restorations can't provide: they may help stop future bone loss. The jawbone life cycle depends on stimulation from the attached tooth as you bite and chew — stimulation that ends when you lose the tooth. Traditional dentures and other restorations can't replicate that stimulation. Implants, on the other hand, directly encourage bone growth and can stop gradual bone loss.

If you need some form of total teeth replacement, consider one supported by implants. You may find they'll provide an excellent long-term solution to both function and appearance.
