TheseDigitalToolsIncreasetheSuccessRateofDentalImplants

Nothing beats the form and function of a real tooth—but dental implants come pretty close. That's why they're tops among both dentists and patients for replacing missing teeth.

Much of an implant's functionality and durability can be credited to its material construction, from the titanium metal post imbedded in the jawbone to the lifelike porcelain crown attached at its other end. But an implant's “nuts and bolts” isn't the only reason why this premier dental restoration is so popular: A good portion of their success comes from the adjunct support provided by digital technology.

Without this varied array of computer-based applications used in planning, designing and installing them, implants couldn't produce the level of satisfactory outcomes they currently do. Here then are a few of the high-tech tools dentists use to make sure your implants result in a winning smile.

CBCT scanning. Implant placement requires a high degree of precision often complicated by various anatomical structures like nerves, blood vessels and sinuses within the gums and jaws. Cone Beam Computer Tomography (CBCT) scanners rotate around a patient's head, taking hundreds of digital x-ray images that are then assembled into a 3-D model image. Dentists can view this model from various angles to identify obstacles and better pinpoint the best implant locations.

Digital impressions. Dentists can also create a 3-D digital impression model of the inside of a patient's mouth that can give them views of their current teeth and gums from any angle. This aids in determining the size and type of implant so that it blends seamlessly with remaining teeth. A digital impression can also provide both the dentist and patient a preview appearance of their future smile after treatment.

3-D printed surgical guides. To accurately drill the implant site during surgery, dentists often create a custom-made device called a surgical guide that fits into the patient's mouth during the procedure. Using results from scanning and digital impressions, highly accurate guides can be created with a 3-D printer. This further ensures that the implant will be in the exact best location for the most attractive and functional outcome.

Implantology is as much art as it is science in achieving a beautiful smile. These and other digital tools help make that desirable end a reality.

HeresWhattoExpectBeforeDuringandAfterImplantSurgery

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.

IfAppropriateAntibioticsbeforeImplantSurgeryCouldReduceInfectionRisk

Millions of microorganisms call your mouth home—and while most are friendly, some are not. An invasive procedure like implant surgery can disrupt the mouth's soft tissues and allow disease-causing bacteria to enter the bloodstream.

This isn't necessarily a major concern if your immune system is sound—your body will move quickly to quash any developing infection. But if your body's defense is weak or compromised by other health conditions, an ensuing infection could cause you problems. In the case of a dental implant, a localized infection around it could lead to its failure.

The bone normally grows and adheres to the surface of an implant soon after it's placed, giving it the added strength and durability for which implants are best known. A bacterial infection, though, could impede bone integration and weaken the implant's hold within the jaw.

One way to avoid this is by treating patients at high risk for infection with an antibiotic before the procedure. In one recent study, researchers concluded that patients receiving a 2-gram dose of amoxicillin an hour before implant surgery helped reduce the risk of future implant failure.

But before taking this route, the dentist must first decide whether antibiotic pre-treatment might be more detrimental than beneficial to an individual patient. Antibiotics can cause side effects in certain people ranging from diarrhea to allergic reactions. Healthcare providers must also be prudent with administering antibiotics for the good of society in general—overuse can potentially give rise to antibiotic-resistant bacteria.

A number of healthcare associations highly recommend antibiotic pre-treatment for any dental patient with prosthetic heart valves, a history of infective endocarditis, a heart transplant and similar heart conditions. They also recognize patients with conditions like prosthetic joints, weakened immune systems, diabetics or other serious health problems could also benefit from antibiotic pre-treatment, but leave it to the physician's discretion on whether or not it's appropriate for an individual patient.

If you're planning to undergo implant surgery or a similar procedure and are concerned about infection, speak with your dentist about whether you would qualify and benefit from antibiotic pre-treatment. If appropriate, taking an antibiotic beforehand could minimize your infection risk.

YourTeenagernotReadyforanImplantHeresWhatWeCanDoInstead

Losing a tooth can be traumatic, but a dental implant can dramatically turn that experience around. Providing functionality, life-like appearance and durability, implants stand out as the premier restoration for lost teeth.

For adults, that is. An older child or teenager with a missing tooth may need to wait a few more years for an implant. The reason: jaw development. A person's jaws, particular the upper jaw, continue to grow with most growth completed by early adulthood. Natural teeth with their periodontal attachments develop right alongside the jaw.

But because an implant attaches directly to the jawbone, its position is fixed: it won't change as the jaw grows and may gradually appear to sink below the gum line. That's why we wait to place an implant until most of jaw maturity has occurred after full jaw maturity. For females, we try to wait until 20 years of age and for males, usually 21 years of age. These are guidelines as some people mature faster and some slower, so a discussion with your dentist or surgeon is necessary to make an educated decision.

While we wait, we can install a temporary replacement for a child's or teenager's lost tooth, usually a partial denture or fixed modified ("Maryland") bridge. The latter affixes a prosthetic (false) tooth in the missing tooth space by attaching it to the back of natural teeth on either side with bonded dental material. It differs from a traditional bridge in that these supporting teeth aren't permanently altered and crowned to support the bridge.

During the time before implants we should understand that the area where the implant will be placed will undergo some bone deterioration, a common consequence of missing teeth. Forces generated as we chew travel through the teeth to stimulate renewing bone growth all along the jawbone. But with a lost tooth the chewing stimulation ceases at that part of the bone, slowing the growth rate and leading to gradual bone loss.

Fortunately, the titanium posts of dental implants stimulate bone growth as bone cells naturally grow and adhere to their surfaces. Before then, though, if the bone volume is diminished, we may need to graft bone material to stimulate bone growth that will enlarge the jaw bone enough for an implant to be placed.

It usually isn't a question of "if" but "when" we can provide your child with an implant for their missing tooth. In the meantime, we can prepare for that day with a temporary restoration.

Answers:
  1. b. The concept of dental implants goes back to the Mayan civilization in 600 AD.
  2. a. The word endosseous (from endo meaning within and osseo meaning bone) refers to the implant's ability to fuse with or integrate with the bone in which it is placed.
  3. b. Most implants are made of a titanium alloy, a metallic substance that is not rejected by the body and is able to fuse with the bone.
  4. a. The term “implant” refers to the root replacement, which is anchored in the gum and bone. A crown is put around the implant where it emerges from the gumline.
