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.

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.
Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.
But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.
As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.
Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.
Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.
This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.
If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

Getting dental implants is going to require surgery. But don't let that concern you—it's a relatively minor procedure.
Currently the “gold standard” for tooth replacement, an implant consists of a titanium post surgically imbedded in the jawbone. We can affix a life-like crown to a single implant or support a fixed bridge or removable denture using a series of them.
Because placement will determine the restoration's final appearance, we must carefully plan implant surgery beforehand. Our first priority is to verify that you have adequate jawbone available to support an implant.
Additionally, we want to identify any underlying structures like nerves or blood vessels that might obstruct placement. We may also develop a surgical guide, a retainer-like device placed in the mouth during surgery that identifies precisely where to create the holes or channels for the implants.
After numbing the area with local anesthesia, we begin the surgery by opening the gum tissue with a series of incisions to expose the underlying bone. If we've prepared a surgical guide, we'll place it in the mouth at this time.
We then create the channel for the insert through a series of drillings. We start with a small opening, then increase its size through subsequent drills until we've created a channel that fits the size of the intended implant.
After removing the implant from its sterile packaging, we'll directly insert it into the channel. Once in place, we may take an x-ray to verify that it's been properly placed, and adjust as needed. Unless we're attaching a temporary crown at the time of surgery (an alternate procedure called immediate loading), we suture the gums over the implant to protect it.
Similar to other dental procedures, discomfort after surgery is usually mild to moderate and manageable with pain relievers like acetaminophen or ibuprofen (if necessary, we can prescribe something stronger). We may also have you take antibiotics or use antibacterial mouthrinses for a while to prevent infection.
A few weeks later, after the bone has grown and adhered to the implant surface, you'll return to receive your new permanent crown or restoration. While the process can take a few months and a number of treatment visits, in the end you'll have new life-like teeth that could serve you well for decades.

An estimated 35 million people in the United States are missing all of their teeth on at least one jaw. Your situation may not be as serious — perhaps you've only lost one tooth. But even one missing tooth could eventually impact the health of underlying bone or other teeth — and it can certainly mar an otherwise attractive smile.
Depending on other health factors, you could be an ideal candidate for a dental implant to replace that missing tooth. Since their introduction in the 1980s, implants have rapidly become the popular choice for tooth replacement. They've gained this popularity for several reasons: they're a life-like replacement that also functions like a tooth; they're adaptable to a variety of situations; and they enjoy a 95%-plus success rate.
The key to their success lies in their unique construction: they replace the tooth root, not just the crown. They accomplish this through a metal titanium post imbedded directly into the bone. The titanium attracts bone cells, which eventually grow and adhere to the post to anchor the implant securely in the jaw. This growth also deters bone loss that occurs after tooth loss and continues after acquiring other forms of removable restorations like full or partial dentures.
If implants have one drawback, though, it's their cost, especially if you have multiple lost teeth. The good news if you're missing several teeth is that each tooth does not need an implant due to their inherent strength. As few as two implants could replace three to four missing teeth or play a role as supports for other restorations like removable dentures. Some of the implants' other benefits will also carry over, including enhanced bone health.
To determine if dental implants are a good choice for your missing teeth, you'll need to undergo an evaluation of your individual dental condition (including bone health). From there we can advise you on whether implants could change your dental health and your smile.

When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.
Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.
But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.
CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.
Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.
Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.
Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.
