If you’re considering different options for tooth replacement, dental implants are likely high on your list. Implants have a proven reputation for both durability and life-like appearance that can restore mouth function and revitalize your smile.
There is one aspect concerning implants, however, which gives people pause — the surgical procedure required to place the implants in the jawbone. If you’re leery about undergoing this procedure we can put your mind at ease — for most patients implant surgery is a minor, pain-free process with little discomfort afterward.
While there are variations in style, implants generally have two major components: a titanium post that’s implanted into the jawbone and a permanent life-like crown that’s affixed 6 to 12 weeks after implant surgery. Titanium is the metal of choice because of its affinity with bone cells; over time bone will grow to and attach itself around the implant, a process known as osseo-integration. The metal post is normally spiral in shape, allowing it more surface area for bone to adhere to.
In the beginning of the procedure we administer local anesthesia to fully numb the area before proceeding. After accessing the bone through tiny incisions in the gum tissue, we create a small channel in the exposed bone. A surgical guide may be used to prepare the precise location for the implant with a series of drilling sequences that increases the channel until it matches the implant size. While this takes place, you should only feel a mild vibration and a little pressure from the drill.
The implants are then removed from their sterile packaging and placed immediately into the prepared site. The gum tissues are then sutured into place with self-absorbing sutures. Most people have only mild discomfort after the surgery that can be managed with a prescription-strength non-steroidal anti-inflammatory drug like ibuprofen. We may also prescribe antibiotics and other care instructions to ensure successful gum tissue healing.
With proper planning and precise implant placement by skilled hands, implant surgery is an easy and uneventful procedure. And, with your new crowns in place, your new, beautiful smile will make the experience a distant memory.

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.
