Understanding Dental Implants: What They Are and How They Work
A dental implant is a replacement tooth system that consists of three main parts working together. The implant itself is a small titanium post that a dentist surgically places into your jawbone where a tooth is missing. Titanium is used because it's biocompatible, meaning your body accepts it as part of you rather than rejecting it as a foreign object. Over several months after placement, the bone around the implant fuses with the titanium through a process called osseointegration. This creates a stable foundation similar to a natural tooth root.

The second component is the abutment, which is a connector piece that screws onto the top of the implant once the bone has healed. The abutment serves as the bridge between the implant and the visible tooth portion. The third part is the crown, which is the artificial tooth that sits on top of the abutment. This crown is custom-made to match the color, size, and shape of your surrounding natural teeth, making it virtually indistinguishable from your real teeth.
The entire implant process typically takes between three to six months from start to finish, though this varies based on individual healing and bone quality. During this time, you'll have multiple dental visits for surgery, healing checks, and restoration work. Unlike dentures or bridges that sit on top of your gums or require grinding down adjacent healthy teeth, implants preserve your natural jaw structure and don't affect nearby teeth.
According to the American Academy of Implant Dentistry, there are approximately 3 million people in the United States with dental implants, and that number grows by about 500,000 each year. This widespread use demonstrates that implants have become an established, well-understood treatment option. Success rates for dental implants typically range from 95 to 98 percent when placed and maintained properly.
Practical takeaway: Dental implants are a multi-part system that mimics your natural tooth structure. Understanding that they require surgical placement and several months of healing helps you know what to expect if you pursue this option.
Types of Dental Implants Available in Armington and Beyond
While dental implants may seem like a single solution, several variations exist to address different tooth loss situations. The most common type is the endosteal implant, which is placed directly into the jawbone. This is the standard choice for most patients and comes in various shapes and designs. Endosteal implants work well when you have sufficient bone height and width to support them. They're often made from titanium and can support either a single crown, multiple teeth as part of a bridge, or even a full set of teeth.

Another type is the subperiosteal implant, which sits on top of the jawbone but under the gums rather than being inserted into the bone itself. This option is less commonly used today but may be recommended for patients who have significant bone loss and prefer to avoid bone grafting procedures. Subperiosteal implants require less bone but can sometimes be less stable than endosteal implants.
Zygomatic implants are specialized implants that anchor into the cheekbone rather than the jaw. These are reserved for specific situations where jawbone height is severely compromised and are performed less frequently than standard implants. They require specialized training to place and aren't suitable for most patients.
Implants also differ in their surface texture and design. Some have a smooth surface, while others have a textured or roughened surface that promotes faster bone integration. Your dentist in Armington will discuss which surface type might work best for your specific bone quality and density. Additionally, implants come in various diameters and lengths to accommodate different spaces in your mouth and different bone thicknesses.
Mini implants represent another variation, measuring about 3 millimeters in diameter compared to standard implants that are 4 to 6 millimeters. Mini implants require less bone and may be useful in areas where space is limited. However, they typically support only one tooth and aren't recommended for areas that experience heavy chewing forces.
Practical takeaway: Different implant types exist for different situations. Understanding these variations helps you learn what options a dentist might discuss with you based on your individual anatomy and tooth loss pattern.
The Dental Implant Process: Step-by-Step What to Expect
The journey to getting a dental implant begins with a comprehensive evaluation appointment. During this visit, your Armington dentist will examine your mouth and take X-rays or three-dimensional CT scans to assess your bone structure, density, and height. This imaging is crucial because it determines whether you have sufficient bone to support an implant or whether bone grafting might be necessary first. The dentist will also review your medical history, current medications, and any conditions that might affect healing, such as diabetes or previous radiation therapy.

If bone grafting is needed, this happens as a separate procedure several months before implant placement. Bone graft material comes from various sources: your own bone harvested from another part of your jaw or body, donor bone from a bone bank, synthetic bone substitute, or a combination of these materials. After grafting, the new bone must integrate with your existing jaw bone, typically taking four to twelve months depending on the amount of bone needed.
Once you have adequate bone, the surgical implant placement happens under local anesthesia, though sedation options are often available. During this procedure, the dentist makes an incision in your gum to expose the bone, then carefully drills a hole and inserts the titanium implant. The gum is then stitched closed, and the implant begins the osseointegration process. This healing phase typically takes three to six months. During this time, you'll need to follow specific care instructions including soft diet recommendations and careful oral hygiene practices.
After osseointegration is complete, you'll return for the abutment placement procedure. This is usually simpler than the initial surgery and often requires only minor local anesthesia or numbing. The dentist exposes the implant, removes the temporary screw cap, and attaches the abutment. Once the abutment is in place, impressions of your teeth are taken so the permanent crown can be custom-made in a laboratory.
The final step is crown placement. Your dentist will try in the new crown to check fit and bite alignment, make any necessary adjustments, and then permanently cement or screw it into place. From start to finish, expect the entire process to take anywhere from four months to over a year, depending on your individual healing and any preliminary procedures needed.
Practical takeaway: The implant process is methodical with distinct phases. Knowing the timeline and what happens at each stage helps you prepare mentally and physically for the commitment involved.
Bone Grafting and When It May Be Necessary
Not everyone has sufficient bone to support a dental implant, particularly if teeth have been missing for an extended period. When bone is present in the jaw but insufficient in height or width, bone grafting procedures can build up the bone before implant placement. This is one of the most common preliminary procedures performed before implant surgery.

Several factors determine whether you might need bone grafting. If you've had a tooth missing for more than a year, significant bone loss has likely already occurred. The body naturally resorbs bone that no longer supports a tooth root. Severe gum disease, previous dental trauma, or certain medical conditions can also lead to inadequate bone. X-rays and CT scans during your initial consultation will reveal exactly how much bone is present and whether grafting would be beneficial.
Bone graft materials come from multiple sources. Autografts use bone from your own body, typically harvested from your jaw, hip, or tibia. This material has excellent integration potential because it contains living cells and proteins from your own body. However, it requires a second surgical site, which increases procedure time and recovery. Allografts use bone from a human donor, typically from a bone bank. This material has been processed to remove cells and pathogens while maintaining the mineral structure that promotes bone growth. Xenografts use bone from animal sources, most commonly bovine (cow) bone. Like allografts, these are processed to be safe and effective.
Synthetic bone substitutes, made from materials like calcium phosphate or hydroxyapatite, provide a scaffold for your body's natural bone to grow into. Some of the newest options combine synthetic materials with growth factors that stimulate bone formation. Many dentists use a combination approach, mixing autograft with allograft or xenograft
