Installing dental implants involves more than the mechanics of placing them into the jawbone. Ultimate success — a natural and beautiful smile — requires painstaking attention to detail and artistry.
Here are a few of the factors we must consider to achieve a smile with dental implants you’ll be proud to display.
The amount of available bone. For the permanent crown to appear natural, it’s crucial to position the implant precisely. To achieve this precision requires an adequate amount of bone to be present. Unfortunately, bone loss is quite common after tooth loss; to minimize this we place bone grafts in the empty socket if at all possible after extraction to encourage bone growth. It’s also possible in some cases to perform bone grafting surgery before implants to build up bone volume.
Your genetic gum tissue type. There are basically two types of gum tissue people are born with: thin or thick. Thin tissues are more subject to wear, difficult to work with during surgery and can make it difficult to hide the metal components of an implant. Thicker tissues are easier to work with, but can have a tendency to overgrow.
Achieving a natural “emergence profile.” To look natural, the implant crown must appear to seamlessly emerge from the surrounding gum tissue. To achieve this, we must carefully plan and place the implant in the precise location in the bone, taking into account the implant shape and how far it should be placed within the bone to match the position and height of adjacent teeth and gum tissues.
Blending color shades with adjacent natural teeth. When it comes to color, everyone has subtle differences in tooth shades and hues. In fact, there are slight color variations within individual teeth, from the root to the tip of the crown. To make sure the implant blends in with adjacent teeth, it’s important to match the color incorporated into the porcelain crown with the natural crowns beside them.
These and other factors require both technical expertise and a sense of artistry. Carefully considering all of them will help ensure your dental implants result in the smile you want.

For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.
This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.
In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.
One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.
If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

If you smoke, you know better than anyone how a hard a habit it is to kick. If you want to quit, it helps to have a motivating reason—like lowering your risk for cancer, cardiovascular disease or similar conditions.
Here’s another reason for quitting tobacco: it could be making your teeth and gums less healthy. And, if you’re facing a restoration like dental implants, smoking can make that process harder or even increase the risk of failure.
So, to give your willpower some needed pep talk material, here are 3 reasons why smoking doesn’t mix with dental implants.
Inhaled smoke damages mouth tissues. Though you may not realize it, the smoke from your cigarette or cigar is hot enough to burn the top layer of skin cells in your mouth, which then thickens them. This could affect your salivary glands causing them to produce less saliva, which in turn could set off a chain of events that increases your risk of tooth decay or periodontal (gum) disease. The end result might be bone loss, which could make installing dental implants difficult if not impossible.
Nicotine restricts healthy blood flow. Nicotine, the chemical tobacco users crave, can restrict blood flow in the tiny vessels that course through the mouth membranes and gums. With less blood flow, these tissues may not receive enough antibodies to fight infection and fully facilitate healing, which could interfere with the integration of bone and implants that create their durable hold. Slower healing, as well as the increased chances of infection, could interrupt this integration process.
Smoking contributes to other diseases that impact oral health. Smoking’s direct effect on the mouth isn’t the only impact it could have on your oral health. As is well known, tobacco use can increase the risk of systemic conditions like cardiovascular and lung disease, and cancer. These conditions may also trigger inflammation—and a number of studies are showing this triggered inflammatory response could also affect your body’s ability to fight bacterial infections in the mouth. Less healthy teeth, gums and underlying bone work against your chances of long-term success with implants.

Dental implants have become the standard for long-term tooth replacement. From mechanics to movie stars, people from all walks of life have discovered the advantages of replacing a missing tooth with an implant. Obviously, restoring your smile is a definite advantage, but an implant can also help to maintain the health of your jawbone and adjacent teeth.
The implant is a small, screw-like titanium post that is placed into your jawbone to function as the root part of the tooth. The living bone tissue will actually attach to the titanium post, fusing them together. This will not only provide a sturdy anchor for a natural-looking crown, but will provide stability for bridgework or dentures. You will then be able to smile, chew and talk as if all of your teeth are natural. The procedure will also help to stabilize the bone, reducing long-term bone loss that occurs when a missing tooth is not replaced.
At this point, if you are thinking that there must be a lot of pain involved, I have good news for you. There is very little pain involved after the procedure is completed and no pain at all during the procedure. Typically, it is a routine surgery that takes place in a dentist’s office under local anesthesia where the immediate area is numbed. If there is any apprehension at all about the procedure, we will offer alternative anesthesia or sedation options during the planning process.
To determine who will be a good candidate for the implant procedure, a plan must be in place to assure the success of the implant. Part of the plan includes:
- Reviewing your past medical and dental history. We must know your complete past and present medical history and medication use, since good health is essential. There are certain conditions and diseases that can affect the healing of an implant.
- Performing a comprehensive dental examination. An evaluation of your dental problems and needs will determine if implants are in your best interests. An assessment of the health and mass of the jawbone as well as the number and location of the implant(s) that are needed to restore your bite and smile back to health will also be determined.
When the implant procedure has been successfully completed, there is one more step. As with your natural teeth, preventive maintenance is crucial for long-term success. A daily routine of brushing and flossing along with regular professional dental cleanings and checkups will help ensure continued gum health and proper functioning of your implants.

Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.
