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.

Along with fessing up to cherry tree surgery and tossing silver dollars across the Potomac River, George Washington is also famously known for wearing wooden dentures. Although we can't verify the first two legends, we can confirm Washington did indeed wear dentures, but not of wood—hippopotamus ivory and (yikes!) donated human teeth—but not wood.
Although they seem primitive to us today, Washington's dentures were the best that could be produced at the time. Still, the Father of Our Country suffered mightily from his dentures, both in physical discomfort and social embarrassment. Regarding the latter, our first president's dentures contorted his lips and mouth in an unattractive way, faintly discernable in Gilbert Stuart's famous portraits of our first president.
If only Washington had lived in a later era, he might have been able to avoid all that dental unpleasantness. Besides better versions of dentures, he might also have benefited from an entirely new way of replacing teeth—dental implants. Just four decades after this state-of-the-art restoration was first introduced, we now recognize implants as the "Gold Standard" for tooth replacement.
In recognition of Dental Implant Month in September, here are 4 reasons why dental implants might be the right tooth replacement choice for you.
Life-like. While other restorations provide a reasonable facsimile of natural teeth, implants take like-likeness to another level. That's because the implant replaces the root, which then allows for a life-like crown to be attached to it. By positioning it properly, implants and the subsequent crown can blend seamlessly with other teeth to create an overall natural smile appearance.
Durable. Implants owe their long-term durability (more than 95% still functioning after ten years) to a special affinity between bone and the titanium post imbedded in the jaw. Bone cells readily grow and adhere to the implant's surface, resulting over time in a more secure hold than other restorations. By the way, this increased bone growth around implants can help slow or even stop progressive bone loss.
Low impact. Dental bridges are another well-regarded tooth replacement option, but with a major downside: The natural teeth on either side of the missing teeth gap must be crowned to support the bridge. To prepare them, we must permanently alter these teeth. Implants, though, don't require this form of support, and so have a negligible effect on other teeth.
Versatile. Although implants are a practical choice for individual tooth restorations, multiple teeth replacements can get expensive. Implants, though, can also be incorporated into other restorations: Four to six implants can support an entire removable denture or fixed bridge. Implant-supported restorations are more durable than the traditional versions, while also encouraging better bone health.

Around one in ten U.S. adults have diabetes, a metabolic disease that can disrupt other aspects of a person's health like wound healing and vision. It could also cause complications with dental implants, the premier replacement choice for missing teeth.
There are two basic types of diabetes. In type 1 diabetes, the pancreas stops producing insulin, a hormone needed to regulate the amount of sugar glucose in the bloodstream. With the more prevalent type 2 diabetes, the body either doesn't produce enough insulin or doesn't respond efficiently to the insulin produced.
Uncontrolled diabetes can contribute to several dangerous health conditions. In addition to vision impairment and poor wound healing, diabetics are at higher risk for other problems like kidney disease or nerve damage. Drastic swings in blood glucose levels can also cause coma or death.
Many diabetics, though, are able to manage their condition through diet, exercise, medications and regular medical care. Even so, they may still encounter problems with wound healing, which could complicate getting a dental implant.
An implant is composed of a titanium metal post imbedded into the jawbone. Because of its affinity with titanium, bone cells naturally grow and adhere to the implant's metal surface. Several weeks after implant surgery, enough bone growth occurs to fully secure the implant within the jaw.
But this integration process may be slower for diabetics because of sluggish wound healing. It's possible for integration to not fully occur in diabetic patients after implant surgery, increasing the risk of eventually losing the implant.
Fortunately, though, evidence indicates this not to be as great a concern as once thought. A number of recent group studies comparing diabetic and non-diabetic implant patients found little difference in outcomes—both groups had similar success rates (more than 95 percent).
The only exception, though, were diabetic patients with poor glucose control, who had much slower bone integration that posed a threat to a successful implant outcome. If you're in this situation, it's better if you're first able to better control your blood glucose levels before you undergo surgery.
So, while diabetes is something to factor into your implant decision, your chances remain good for a successful outcome. Just be sure you're doing everything you can to effectively manage your diabetes.

Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.
In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.
Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.
Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.
If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.
The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.
Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.
Losing a tooth from disease or accident can be traumatic. The good news, though, is that it can be replaced with a life-like replica that restores your smile. One of the most popular and durable solutions is a dental implant, which replaces not only the root of the tooth but the crown as well.
But there's a possible wrinkle with implants — for accurate placement there must be a sufficient amount of bone around it. This could be a problem if you've been missing the tooth for sometime: without the stimulus provided by a tooth as you chew, older bone cells aren't replaced at an adequate rate. The bone volume gradually diminishes, as up to 25% of its normal width can be lost during the first year after tooth loss. A traumatic injury can damage underlying bone to an even greater extent.
There is a possible solution, but it will require the services of other specialists, particularly a periodontist trained in gum and bone structure. The first step is a complete examination of the mouth to gauge the true extent of any bone loss. While x-rays play a crucial role, a CT scan in particular provides a three-dimensional view of the jaw and more detail on any bone loss.
With a more accurate bone loss picture, we can then set about actually creating new bone through grafting procedures. One such technique is called a ridge augmentation: after opening the gum tissues, we place the bone graft within a barrier membrane to protect it. Over time the bone will grow replacing both the grafting material and membrane structure.
Once we have enough regenerated bone, we can then perform dental implant surgery. There are two options: a “one-stage” procedure in which a temporary crown is placed on the implant immediately after surgery; or a “two-stage” in which we place the gum tissue over the implant to protect it as it heals and bone grows and attaches to it. In cases of pre-surgical bone grafting, it's usually best to go with the two-stage procedure for maximum protection while the bone strengthens around it.
Necessary preparation of the bone for a future dental implant takes time. But the extra effort will pay off with a new smile you'll be proud to display.
