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.

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.

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.
If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

You've seen ads for “Teeth in One Day” that promise immediate implant placement at the same time you have the problem tooth removed. But this presumes the gums and underlying bone are healthy and able to support and protect the implant. If that's not the case, it may be ill-advised to place an implant on the same day.
Even with immediate placement, there will be a small degree of bone and gum opening or space around the implant after it's placed into the socket. This can often be remedied by placing a bone graft and sometimes a gum graft when we install the implant. It's also possible for natural healing to gradually fill in the space, but we'll need to monitor the site carefully for several weeks.
On the other hand, if we detect significant bone loss (or strongly suspect it will occur), immediate placement may not be an option — there's not enough bone or it's too weak to support an implant. In this case, it's necessary to wait on placement and focus on improving the bone health and quantity, beginning when we remove the old tooth and place a bone graft.
After completing the extraction, we typically place a bone graft in the empty socket. The graft will become a “scaffold” for new bone cells to grow upon. We may then allow about two to four months for new bone to partially replenish the area and then place the implant. The bone will continue to regenerate as it grows and attaches to the titanium implant to create a solid attachment.
If the site, however, still appears fragile even after partial bone growth, we may opt to wait another two to four months before attempting placement. From a long-term perspective, this is the best scenario for ensuring a durable foundation for the implant. It also allows for a socket severely compromised by disease to heal more thoroughly.
To determine which of these placement scenarios is best for you, we'll first need to conduct a thorough dental examination. From there we'll be in a better position to discuss the right implant timeline for your situation. Our main goal is to ensure we can securely place your implant in just the right position to achieve the most successful and attractive result.
