Are you interested in dental implants but a little hesitant about the surgery? Don’t be—this procedure to imbed an implant’s titanium post in the jawbone is relatively minor with little to no discomfort for most patients.
Some time before, however, we’ll need to pre-plan the surgery to pinpoint the best location for the implant, critical to achieving a solid hold and a life-like appearance. During these first visits we often create a surgical guide, a device inserted in the mouth during surgery that identifies the exact location for the hole (or channel) in the bone we’ll drill to insert the implant.
On surgery day, we’ll prepare you for a pain-free and relaxing experience. If you’re normally anxious about dental work, we may prescribe a sedative for you to take ahead of time. As we begin we’ll thoroughly numb the area with local anesthesia to ensure you won’t feel any pain.
The surgery begins with an incision through the gum tissue to access the underlying bone. Once it’s exposed, we’ll insert the surgical guide and begin a drilling sequence to gradually increase the size of the channel. This takes time because we want to avoid damaging the bone from overheating caused by friction.
Once we’ve created a channel that matches precisely the implant’s size and shape, we’ll remove the implant from its sterile packaging and immediately fit and secure it in the channel. We’ll then take x-rays to ensure it’s in the best position possible.
Satisfied we’ve properly situated and secured the implant, we’ll suture the gum tissue back in place to protect the implant with or without attaching a healing abutment to it as it fully integrates with the jawbone over the next few months (after which you’ll come back to receive your permanent crown). After a short recovery, you’ll return to full activity. Most patients only experience mild to moderate discomfort usually manageable with over-the-counter pain medication like aspirin or ibuprofen.
While implantation is a long process, you’ll be obtaining what’s considered by most dentists and their patients as the most durable and life-like tooth replacement available. Your new attractive smile will be well worth it.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

If you've lost a tooth, you have a number of options for replacing it. Perhaps the best choice in terms of lifelikeness and durability is a dental implant.
All implants have the same basic architecture: a titanium metal post imbedded in the jawbone to replace the root; and an abutment, a metal collar that links the post with a lifelike porcelain crown. But implants can vary in how the crown attaches to the abutment and post — either cemented to the abutment or screwed through the abutment to the post.
Either method will permanently secure the crown to the implant. But there are advantages and disadvantages for each.
A screw-retained crown may better facilitate any future repair that might be needed. For a skilled dentist it's a simple matter of removing the screw and then the crown from the abutment. There's less risk of damage to the implant during repairs or crown replacement. Many dentists also prefer screws for crowns placed at the same time they're installing the implant post (a procedure called immediate loading).
The screw access hole, however, could pose a cosmetic problem. Although we can cover it over with tooth-colored filling, it may still be noticeable and unattractive especially for a tooth visible when you smile (in the smile zone). There's also the possibility the porcelain around the access hole could chip.
By contrast, cemented crowns have a smooth, unbroken surface and are aesthetically ideal for smile zone teeth. But the cement could interact poorly with gum and bone tissue in some patients, causing inflammation and possible bone loss.
And unlike screw-retained crowns, cemented crowns are difficult to remove for implant repair. We may have to drill through the crown to access the screw between the abutment and the post, and then repair it cosmetically if we use the same crown. Again, the final result may not be quite as visually appealing.
In the end, it will depend on the implant's location, how your body reacts to the cement or your dentist's preference. In either case, though, you'll have a tooth replacement that's functional, life-like and able to endure for many years to come.

If you’ve just received a dental implant restoration, congratulations! This proven smile-changer is not only life-like, it’s also durable: more than 95% of implants survive at least 10 years. But beware: periodontal (gum) disease could derail that longevity.
Gum disease is triggered by dental plaque, a thin film of bacteria and food particles that builds up on teeth. Left untreated the infection weakens gum attachment to teeth and causes supporting bone loss, eventually leading to possible tooth loss. Something similar holds true for an implant: although the implant itself can’t be affected by disease, the gums and bone that support it can. And just as a tooth can be lost, so can an implant.
Gum disease affecting an implant is called peri-implantitis (“peri”–around; implant “itis”–inflammation). Usually beginning with the surface tissues, the infection can advance (quite rapidly) below the gum line to eventually weaken the bone in which the implant has become integrated (a process known as osseointegration). As the bone deteriorates, the implant loses the secure hold created through osseointegration and may eventually give way.
As in other cases of gum disease, the sooner we detect peri-implantitis the better our chances of preserving the implant. That’s why at the first signs of a gum infection—swollen, reddened or bleeding gums—you should contact us at once for an appointment.
If you indeed have peri-implantitis, we’ll manually identify and remove all plaque and calculus (tartar) fueling the infection, which might also require surgical access to deeper plaque deposits. We may also need to decontaminate microscopic ridges found on the implant surface. These are typically added by the implant manufacturer to boost osseointegration, but in the face of a gum infection they can become havens for disease-causing bacteria to grow and hide.
Of course, the best way to treat peri-implantitis is to attempt to prevent it through daily brushing and flossing, and at least twice a year (or more, if we recommend it) dental visits for thorough cleanings and checkups. Keeping its supporting tissues disease-free will boost your implant’s chances for a long and useful life.

There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.
