While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Dental implants are among the most popular tooth replacements with their high success rate, durability and life-like beauty. But obtaining them is a process that requires commitment, planning, and coordination — it takes a team.
Your general dentist is often the first team member you’ll encounter: because they’re most familiar with your mouth’s condition the implant discussion naturally begins here. They can help you determine if you’re a good candidate for implants, such as if you have sufficient bone mass at the intended site or if you have dental disease that must be treated first. They’ll also continue monitoring your general dental health throughout the process.
Your general dentist may also have the special training for surgically placing implants. If not, he or she may refer you to your next team member: an oral surgeon or periodontist skilled in implantation procedures. This step first requires careful planning, including developing a surgical guide for precise placement of the implant. These specialists may also contribute to other aspects of the implant process such as tooth extraction or bone grafting.
A few weeks after surgery bone will have grown and adhered to the implant to form a solid bond. It’s time for you to go back to your dentist who will work in conjunction with another member of your team, a dental lab technician. Together, your dentist and laboratory technician will guide the development, manufacture and placement of the implant’s life-like porcelain crown. The technician will take their specifications from the surgeon and your general dentist and, with his or her skill and artistry, form a crown that will blend well in color and shape with the rest of your teeth.
We also can’t forget another important team member: you. Without your input, especially in the early planning stages, your expectations for a more attractive smile might not be met. The rest of your implant team depends on you communicating your desires and wishes to balance with the technical requirements they must achieve.
The process for dental implants can take months. But with the coordinated efforts of your implant team you’ll be able to enjoy results — renewed function and a more attractive smile — that could last for decades.

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.

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.
But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.
Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.
Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.
On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

If you have a problem tooth we’ve recommended removing, those “Tooth in one day” ads—a tooth removed and an implant placed at the same time—might start to pique your interest. But there are a few factors we must consider first to determine if this procedure is right for you. Depending on your mouth’s health conditions, you may need to wait a little while between tooth extraction and implantation.
Here are 3 timing scenarios for receiving your implant after tooth removal, depending on your oral health.
Immediately. The “tooth in one day” scenario can be much to your liking, but it could also be tricky in achieving the best results. For one, the implant may fit too loosely—the bone around the socket might first need to heal and fill in or undergo grafting to stimulate regeneration. In other words, immediate implant placement usually requires enough supporting bone and an intact socket. Bone grafting around the implant is usually needed as well.
After gum healing. Sufficient gum coverage is also necessary for a successful outcome even if the bone appears adequate. To guard against gum shrinkage that could unattractively expose too much of the implant, we may need to delay implant placement for about 4 to 8 weeks to allow sufficient gum healing and sealing of the extraction wound. Allowing the gums to heal can help ensure there’s enough gum tissue to cover and protect the implant once it’s placed.
After bone healing. As we’ve implied, implants need an adequate amount of supporting bone for best results. When there isn’t enough, we might place a bone graft (often immediately after tooth extraction) that will serve as a scaffold for new bone to grow upon. Depending on the degree of bone loss, we may wait until some of the bone has regenerated (about 2 to 4 months) and then allow the natural process of bone cells growing and adhering to the implant (osseointegration) to complete the needed bone growth. If bone loss is extensive, we may need to wait until full healing in 4 to 6 months to encourage the most stable outcome.
