Implants are highly regarded by both dentists and patients for their versatility and durability. But it’s their life-like appearance that “seals the deal” as the restoration of choice — not only mimicking an individual tooth, but emerging from the gum line and blending indistinguishably with other teeth in color and symmetry.
To achieve this result, we must consider a few factors beforehand, particularly the amount of bone available at the intended implant site. An implant requires a certain amount of bone to properly position it for the most natural crown appearance. The bone present around adjacent teeth can also affect your appearance: in the absence of adequate bone the papillae, triangular shaped gum tissue between teeth, may not regenerate properly between the implant and the natural teeth. This can leave a noticeable void, what dentists call “black hole disease.”
Bone loss is a significant problem particularly after tooth loss. It’s quite possible for you to lose a quarter of the bone’s width in the first year after tooth loss. To avoid this, we often use bone grafting techniques immediately after extraction to lessen bone loss; if it’s already occurred we may be able to use similar reconstructive techniques to rebuild and encourage renewed bone growth. In the end, though, if there remains a significant level of bone loss it may be necessary to consider another option for tooth replacement other than implants.
The thickness of your gum tissue, a genetic trait, can also have an impact on the implant’s ultimate appearance. Thicker gum tissues are generally more resilient and easier to work with surgically. Thinner gum tissues are more susceptible to recession and tend to be more translucent, which could cause the underlying metal implant to be visible. Thus, working with thinner gum tissues requires a more delicate approach when trying to achieve a visually appealing result.
All these factors must be balanced, from implantation to final crown placement. But with careful planning and attention to detail throughout the process, many of these issues can be overcome to produce a satisfying result — a new and appealing smile.

Dental implants are considered the premier option for tooth replacement. While all implant procedures follow the same general concept — a titanium post surgically inserted into the jawbone with an attached life-like crown — the installation process can vary.
From their earliest history, implants have usually been installed through a two-stage process. In the first stage, the surgeon inserts the titanium post in the bone and leaves it “submerged” below the gum level to protect it from oral bacteria and the effects of chewing and biting. About three months later after the bone attaches to the titanium (a process called osseointegration), the surgeon then performs the second stage by re-exposing the implant and attaching a temporary abutment and crown for the patient to wear while the permanent abutment and crown are fabricated and later attached in 2-6 weeks.
In recent years, advancements in materials and design have made possible a one-stage process that allows the implant to protrude above the gum line during osseointegration and shortens the process. After the initial three-month healing period, the implant is ready for “loading” with the permanent crown.
The choice between which of these two procedures should be used for your implants will first depend on the type of tooth being replaced. A front tooth benefits from the one-stage procedure for cosmetic reasons because the surgeon can install a temporary crown to the exposed abutment during osseointegration (as long as the temporary tooth isn’t in functional contact with other teeth). An implant for a back tooth, on the other hand, doesn't have a large cosmetic demand so those one stage procedures usually end up with an exposed healing abutment but no temporary crown.
The strength of the bone is also a factor. Some bone tends to be softer, particularly in the back of the mouth. There’s a chance the implant could move in this softer bone, adversely affecting the outcome. For this reason, the two-stage procedure can be the preferred approach for posterior teeth as it offers more protection from movement.
You can be sure we’ll consider all these and other factors during your initial examination, and then advise you on the best approach. Above all, we want to make sure — whether a one-stage or a two-stage implant process — the result is a smile you can be proud of.

Dental implants are best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.
That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.
The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.
While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.
We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.
We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.
There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
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.
