Overview of Dental Implants:

Dental implants are artificial tooth roots that a periodontist places into your jaw to hold replacement teeth.  Teeth may be missing due to injury, or may have been extracted due to disease or decay. 

Placing dental implants following an extraction and socket grafting will provide the best long-lasting support for preserving your jawbone and allowing you to function as before.  Dental implants are a permanent solution to missing teeth.

Dentures Vs. Dental Implants:

Dentures:  “The advantage of upper and lower dentures is that they can be constructed quickly and they initially cost less than implants.  They may last a lifetime, but over the years with aging, new sets need to be made to fit the changing gum tissue and chewing surfaces of the teeth in the dentures.”

Dental Implants:  “Dental implants are a major investment and the procedure can be time consuming.  As with any complex surgery, there is always the risk of complication even after a thorough examination and consultation prior to care.  But dental implants are a dependable and life long solution to missing teeth.  Compared with dentures, which can be loose and unstable, implants provide a permanent solution that is both functional and natural in appearance, giving you the confidence to smile and show your pearly whites.”

Dental Implants are a Better Solution to Missing Teeth:

· Esthetic:  “Dental implants look and feel like your own teeth!  Since dental implants integrate into the structure of your bone, they prevent the bone loss and gum recession that often accompany bridgework and dentures. No one will ever know that you have a replacement tooth.”

· Tooth-saving:  “Dental implants don't sacrifice the quality of your adjacent teeth like a bridge does because neighboring teeth are not altered to support the implant.  More of your own teeth are left untouched, a significant long-term benefit to your oral health!”

· Confidence:  “Dental implants will allow you to once again speak and eat with comfort and confidence! They are secure and offer freedom from the irksome clicks and wobbles of dentures.  They'll allow you to say goodbye to worries about misplaced dentures and messy pastes and glues.”

· Reliable:  “The success rate of dental implants is highly predictable. They are considered an excellent option for tooth replacement.”

Benefit of Immediate Implant Placement After a Tooth is Lost:

“As soon as a tooth is lost, either from gum disease or an extraction, the supporting bone in the jaw begins to dissolve.  This process is called resorption. The longer a tooth is missing, the greater the bone loss.

Over time, resorption of the jawbone has a considerable effect on quality of life and on the possibility of replacing the missing teeth.  As teeth are lost it becomes more difficult to eat and chew food.”

“A tooth should be replaced as soon as it is lost. This will retain your oral health by preventing bone loss, reducing movement of surrounding teeth and avoiding excess decay.

Teeth provide more functions than just the ability to chew. They are necessary for the health of the gum and jaw tissues as well, and a prolonged absence of a tooth will severely limit the possibilities for restorations.  Missing teeth may also affect your confidence and well-being.”

Ridge Modification Ensures Bone for Implant to Anchor Into:

“Deformities in the upper or lower jaw can leave you with inadequate bone in which to place dental implants. This defect may have been caused by periodontal disease, wearing dentures, developmental defects, injury or trauma…

To correct the problem, the gum is lifted away from the ridge to expose the bony defect. The defect is then filled with bone or bone substitute to build up the ridge. Your periodontist can tell you about your options for graft materials, which can help to regenerate lost bone and tissue.

Finally, the incision is closed and healing is allowed to take place. Depending on your individual needs, the bone usually will be allowed to develop for about four to 12 months before implants can be placed. In some cases, the implant can be placed at the same time the ridge is modified.

Ridge modification has been shown to greatly improve appearance and increase your chances for successful implants that can last for years to come. Ridge modification can enhance your restorative success both esthetically and functionally.”

Placement of Dental Implants:

“First, implants, which look like screws or cylinders, are placed into your jaw. Then, over the next two to six months, the implants and the bone are allowed to bond together to form anchors for your artificial teeth. During this time, a temporary teeth replacement option can be worn over the implant sites.

Often, a second step of the procedure is necessary to uncover the implants and attach extensions. These small metal posts, called abutments, along with various connecting devices that allow multiple crowns to attach to the implants, complete the foundation on which your new teeth will be placed. Your gums will be allowed to heal for a couple of weeks following this procedure…

Finally, full bridges or full dentures will be created for you and attached to your implants or the connecting device. After a short time, you will experience restored confidence in your smile and your ability to chew and speak.”
