If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

If you've lost a tooth or need to have one extracted, you have to decide how to replace it. Of all the options available none can match both the lifelikeness and function of a dental implant.
A dental implant is a prosthetic (false) tooth that mimics the root of a natural tooth. Once that implant root form fuses to the surrounding bone, we attach the crown, which is the part of the tooth you can see.
While other replacement options like bridges or dentures can restore the lifelikeness of the tooth crown, they don't replace the root. An implant's titanium post can: using a minor surgical procedure we imbed the post into the bone. Because bone cells have a natural affinity with titanium, they will grow around and adhere to the post over a few weeks after surgery. This further adds strength to the implant's hold in the bone.
Although the attachment isn't exactly like natural teeth, it can maintain this hold for many years. And because it encourages bone growth, a dental implant will help minimize bone loss, a natural consequence of losing teeth. Other replacement options can't do that.
Of course, implants are more costly than other restorations. With an attached crown, an implant can replace any number of teeth. But if you have extensive tooth loss, bridges or dentures would be more cost-effective selections.
But even then, implants could still play a role. We can strategically place a small number of implants as supports for a bridge or even a removable denture. Not only will the implants better secure their attachment, they'll also stimulate bone growth.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?
Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?
Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.
Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.
But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?
In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.
Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.
What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

Waiting is part of life for a teenager: waiting to get a driver’s license, to graduate high school or to leave home and stretch their wings. A teenager with lost teeth may also need to wait until they’re older to obtain dental implants.
The reason arises from the differences in how implants and natural teeth attach to the jaw. Although natural teeth may seem rigidly set in the bone, they’re actually held in place by an elastic tissue between them and the bone known as the periodontal ligament. Tiny filaments that attach to the teeth on one side and the bone on the other hold the teeth in place, but also allow the teeth to move gradually in response to mouth changes.
A titanium implant post doesn’t have this relationship with the periodontal ligament — it’s attached directly to the jaw bone. Over time the bone, which has a special affinity with titanium, grows and adheres to it to form a durable bond without an attachment to the periodontal ligament. Because of this the implant can’t move like a natural tooth.
This is extremely important for implant placement because the jaws in particular won’t fully develop in most people until their late teens or early twenties: the upper jaw in particular will tend to grow out and down. Natural teeth accommodate to these changes, but the implant can’t — it will appear to retreat into the jaw. The gum tissues surrounding the implant also won’t conform to the continuing growth and may appear receded.
The best approach is to choose a temporary replacement option until the jaws and other facial bone structures have finished growing. One example is a bonded bridge in which we use a bonding agent to attach a bridge of artificial teeth to teeth on either side of a missing tooth — bonding won’t permanently alter them as with a traditional bridge. Once the jaws have finished growing, we can remove the bonded bridge and install the more permanent implant.
Ask any teenager: waiting can be hard. But with dental implants, waiting until the right time will help ensure the attractive result is a permanent one.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.
