ShouldYouTakeanAntibioticBeforeImplantSurgery

Although getting an implant requires surgery, it's usually a minor affair. Chances are good that after just a few days recuperation you'll be back completely to your normal activities.

But like many other minor surgeries, an implant procedure does pose a slight risk of post-op infection. That's especially so with any dental procedure like implant surgery, since the mouth harbors numerous strains of bacteria that could escape into the bloodstream. For most people, though, a post-op infection doesn't pose a major problem since their immune system kicks in immediately to defeat it.

But some patients with less than robust immune systems or other health problems can have serious complications from an infection. Among other things, infected tissues around an implant may not heal properly, putting the implant at significant risk for failure.

If you have a condition that makes a post-op infection problematic, your dentist or physician may recommend you take an antibiotic before your procedure. Known as prophylactic (preventive) antibiotic treatment, it's intended to give a weakened immune system a head-start on any potential infection after a procedure.

Using antibiotics in this way has been a practice for several decades, and at one time were recommended for a wide list of conditions. That's changed in recent years, though, as evidence from numerous studies seems to show the risk to benefit ratio isn't significant enough to warrant its use in all but a handful of conditions.

Both the American Dental Association and the American Heart Association recommend prophylactic antibiotics for patients with prosthetic heart valves, past infective endocarditis, a heart transplant and some congenital heart conditions. Some orthopedists may also recommend it for patients with prosthetic joints.

Even if you don't fall into these particular categories, prophylactic antibiotics may still be beneficial if you have a compromised immune system or suffer from a disease like diabetes or lung disease. Whether or not a prophylactic antibiotic is a prudent step given your health status is a discussion you should have with both your physician and your dentist.

If they feel it's warranted, it can be done safely in recommended doses. If your health isn't as robust as it could be, the practice could give you a little added insurance toward a successful implant outcome.

OvercomingBoneLossPreventingYouFromGettinganImplant

Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.

But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.

This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.

This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.

But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.

Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.

Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

CouldaMetalAllergyStopYouFromGettingDentalImplants

The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.

Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.

It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.

Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.

For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.

That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.

At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

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.
