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.

Around one in ten U.S. adults have diabetes, a metabolic disease that can disrupt other aspects of a person's health like wound healing and vision. It could also cause complications with dental implants, the premier replacement choice for missing teeth.
There are two basic types of diabetes. In type 1 diabetes, the pancreas stops producing insulin, a hormone needed to regulate the amount of sugar glucose in the bloodstream. With the more prevalent type 2 diabetes, the body either doesn't produce enough insulin or doesn't respond efficiently to the insulin produced.
Uncontrolled diabetes can contribute to several dangerous health conditions. In addition to vision impairment and poor wound healing, diabetics are at higher risk for other problems like kidney disease or nerve damage. Drastic swings in blood glucose levels can also cause coma or death.
Many diabetics, though, are able to manage their condition through diet, exercise, medications and regular medical care. Even so, they may still encounter problems with wound healing, which could complicate getting a dental implant.
An implant is composed of a titanium metal post imbedded into the jawbone. Because of its affinity with titanium, bone cells naturally grow and adhere to the implant's metal surface. Several weeks after implant surgery, enough bone growth occurs to fully secure the implant within the jaw.
But this integration process may be slower for diabetics because of sluggish wound healing. It's possible for integration to not fully occur in diabetic patients after implant surgery, increasing the risk of eventually losing the implant.
Fortunately, though, evidence indicates this not to be as great a concern as once thought. A number of recent group studies comparing diabetic and non-diabetic implant patients found little difference in outcomes—both groups had similar success rates (more than 95 percent).
The only exception, though, were diabetic patients with poor glucose control, who had much slower bone integration that posed a threat to a successful implant outcome. If you're in this situation, it's better if you're first able to better control your blood glucose levels before you undergo surgery.
So, while diabetes is something to factor into your implant decision, your chances remain good for a successful outcome. Just be sure you're doing everything you can to effectively manage your diabetes.

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

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.

There’s a lot to like about replacing a missing tooth with a dental implant. This state-of-the-art restoration is by far the most durable and life-like option available. And unlike other replacement options implants stimulate bone growth, a major concern after tooth loss.
For that reason we encourage getting an implant as soon as possible — for adults, that is. We don’t recommend implants for younger patients because even a teenager’s jaws haven’t yet reached full maturity. Because it attaches to the jaw differently, an implant can’t move with the growing jaw as real teeth do. It would eventually look as if it were sinking into the jaw below the gum line or being left behind as the rest of the jaw grows.
It’s best, then, to postpone placing an implant until the jaw fully matures, usually in a patient’s early twenties. In the meantime, there are some things we can do to prepare for a future implant while also restoring the tooth with a temporary replacement.
As previously mentioned, our biggest concern is bone health. Like other living tissue, bone has a growth cycle of older cells dissolving and newer ones forming in their place. The teeth transmit the pressure produced when we chew to the bone to stimulate this growth. With the absence of a tooth, the adjacent bone no longer receives this stimulation — the growth cycle slows and may eventually lead to bone loss.
We can help this situation by placing a bone graft in the missing tooth socket at the time of extraction. The graft serves as a scaffold that’s eventually taken over and replaced by new bone growth. We can also try to control how fast the graft is replaced by using grafting material that’s slowly removed and lasts longer — often a preferable situation if an implant is years away.
As for appearance, we can create a custom partial denture or even a type of bridge that bonds a prosthetic tooth to neighboring teeth without significantly altering them. If the patient undergoes orthodontic treatment it’s also possible to add prosthetic teeth to an orthodontic appliance.
Eventually, we’ll be able to provide the permanent solution of a dental implant. With careful planning and measures to preserve bone health, there’s a good chance the outcome will be worth the wait.
