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.

If you're thinking about getting dental implants, you may be curious about how long it might take. The answer depends on the health of your supporting bone.
Bone is an integral part of implant functionality as bone cells gradually grow and adhere to the newly placed implant to give it its characteristic strength. The implant also requires an adequate amount of bone to accurately position it for the best appearance outcome.
If the bone is sufficient and healthy, we can proceed with the surgical placement of the implant. The most common practice following surgery is to allow a few weeks for the bone integration described previously to take place before finally attaching the crown. With an alternative known as a “tooth in one day” procedure, we install a crown right after surgery, which gives you a full smile when you leave.
There's one caveat to this latter method, though—because the implant still requires bone integration, this immediate crown is temporary. It's designed to receive no pressure from biting or chewing, which could damage the still integrating implant. We'll install the permanent crown after the implant and bone have had time to fully mesh.
So, if your supporting bone is sound, the complete implant process may only take a few weeks. But what if it's not—what if you've lost bone and don't have enough to support an implant? In that case, the length of process time depends on the severity of the bone loss and if we're able to overcome it. In some cases, we can't, which means we'll need to consider a different restoration.
But it's often possible to regenerate lost bone by grafting bone material at the implant site. If the bone loss is moderate, it may take 2 to 4 months of regrowth after grafting before we can perform implant surgery. If it's more significant or there's disease damage to the socket, it may take longer, usually 4 to 6 months. It largely depends on the rate of bone regeneration.
In a nutshell, then, the health of your jaw's supporting bone has a lot to do with whether the implant process will take a few weeks or a few months. Regardless of the time, though, you'll gain the same result—new, functional teeth and a more attractive smile.

Installing dental implants involves more than the mechanics of placing them into the jawbone. Ultimate success — a natural and beautiful smile — requires painstaking attention to detail and artistry.
Here are a few of the factors we must consider to achieve a smile with dental implants you’ll be proud to display.
The amount of available bone. For the permanent crown to appear natural, it’s crucial to position the implant precisely. To achieve this precision requires an adequate amount of bone to be present. Unfortunately, bone loss is quite common after tooth loss; to minimize this we place bone grafts in the empty socket if at all possible after extraction to encourage bone growth. It’s also possible in some cases to perform bone grafting surgery before implants to build up bone volume.
Your genetic gum tissue type. There are basically two types of gum tissue people are born with: thin or thick. Thin tissues are more subject to wear, difficult to work with during surgery and can make it difficult to hide the metal components of an implant. Thicker tissues are easier to work with, but can have a tendency to overgrow.
Achieving a natural “emergence profile.” To look natural, the implant crown must appear to seamlessly emerge from the surrounding gum tissue. To achieve this, we must carefully plan and place the implant in the precise location in the bone, taking into account the implant shape and how far it should be placed within the bone to match the position and height of adjacent teeth and gum tissues.
Blending color shades with adjacent natural teeth. When it comes to color, everyone has subtle differences in tooth shades and hues. In fact, there are slight color variations within individual teeth, from the root to the tip of the crown. To make sure the implant blends in with adjacent teeth, it’s important to match the color incorporated into the porcelain crown with the natural crowns beside them.
These and other factors require both technical expertise and a sense of artistry. Carefully considering all of them will help ensure your dental implants result in the smile you want.

Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
If you’re thinking about getting dental implants, you’re in good company. Dentists have placed more than 3 million of these popular devices since their introduction in the early 1980s.
But if you have multiple missing teeth, you might think the cost of all those individual implants could put them out of your league. Yes, replacing multiple teeth with individual implants can be quite expensive—but implant technology isn’t limited to one tooth at a time. A few well-placed implants can impart their proven durability and stability to other types of restorations.
For example, we can incorporate implants into a bridge for a series of missing teeth. Conventional bridges are normally fixed in place by altering and then crowning natural teeth on each side of the missing teeth gap with a fixed row of prosthetic (false) teeth in the middle to fill it. Instead, two implants placed at the ends of the gap can support the bridge rather than natural teeth. This not only provides greater stability for the bridge, it also avoids permanent altering the natural teeth that would have been used.
Implants can also support a fixed bridge to restore complete tooth loss on a jaw. The new bridge is attached to a few strategically placed implants along the jaw line to equally distribute biting forces. This can result in a strong hold with excellent durability.
We can also use implants to improve traditional dentures. Dentures normally rest directly on the gums’ bony ridges, depending on a snug fit for stability. But bone loss, a natural consequence of missing teeth, can still occur while wearing dentures, which may in fact accelerate the rate of loss due to the appliance’s constant pressure and friction against the gums.
Instead, just a few implants placed along the jaw can, with attachments built into the denture, hold it securely in place. This not only decreases the pressure on the gums, but the natural bone growth that occurs around the implant may even deter bone loss.
Depending on your situation, there could be a viable restoration solution involving implants. Visit our office for a complete examination and evaluation to see if implants could help change your smile forever.
