Overview of Implant Placement

The Surgical Procedure

The procedure to place an implant takes 30 to 60 minutes for one implant and only 2 to 3 hours for multiple implants. The number of appointments and time required, vary from patient to patient. The surgeon will bring great precision and attention to the details of your case.

Prior to surgery, you may receive antibiotics and for greater comfort, intravenous sedation or nitrous oxide (laughing gas). These options are discussed with you at your consultation appointment. A local anesthetic will be administered to numb the area where the implant will be placed.

When you are comfortable, the surgeon makes a small incision in the gum tissue to reveal the bone, creates space using special instruments, and gently inserts the titanium implant. The top of this implant is often visible through the gum. Sometimes it is better in the early stages of healing to have the implant covered by the gum tissue.

The Healing Phase

Now the healing begins. The length of time varies from person to person, depending upon the quality and quantity of bone. In some cases, implants may be restored immediately after they are placed. The surgeon will advise you on follow-up care and timing. After the initial phase of healing, the surgeon places an abutment (support post) or a healing cap onto the implant during a brief follow-up visit. This allows gum tissue to mature and provides access to the implant.

Occasionally, impressions are made at the time the implant is placed. This enables the crown to be ready when the implants have healed. How long your mouth needs to heal is determined by a variety of factors. Follow-up care (one to four appointments) is usually needed to ensure that your mouth is healing well and to determine when you are ready for the restorative phase of your treatment.

It may be beneficial to perform a soft tissue graft to obtain stronger, more easily cleaned and natural appearing gum tissue in the area around the implant. This process involves moving a small amount of gum tissue from one part of your mouth to the area around the implant. Most often, it is a brief and relatively comfortable procedure.

Whether it’s one tooth or all of your teeth that are being replaced, your dentist will complete the restoration by fitting the replacement tooth (crown) to the dental implant.

Dental Implants Presentation

To provide you with a better understanding of dental implants, we have provided the following multimedia presentation. Many common questions pertaining to dental implants are discussed.

When Are Dental Implants Placed?

Implants are often placed several months after extraction. At times, an implant may be placed immediately after extraction of a tooth. This may involve a little more risk, but it simplifies the process—you won’t have to wait for another appointment to place the implant. When infection or other problems with the bone are present, immediate implant placement is not the best treatment.

If your tooth has been missing for some time, the adjacent support bone is likely to grow thinner and shrink. This occurs because the root of the natural tooth has to be present to stimulate the bone. As much as one third of your jaw’s thickness can be lost in the year following tooth extraction. If you are missing enough bone, you may benefit from having additional bone grafted into the area. This ensures the implant will be adequately supported when it is placed in the jaw.

How Many Implants Do I Need?

Most frequently, one implant per missing tooth is placed. Because many of the larger teeth in the back of your jaws have two or three roots, the most common approach is to replace missing back teeth with larger implants.

Single Tooth Implant

If you are missing a single tooth, one implant and a crown can replace it. A dental implant replaces both the lost natural tooth and its root.

Step 1

The need to replace a missing tooth could be the result of an accident or because there was no predisposition for a tooth at birth.

 

Step 2

The dental implant is installed in the jawbone. No healthy teeth are affected or damaged. With other replacement solutions, adjacent teeth might need to be ground down to support a bridge.

 

   Step 3

The abutment is attached to the dental implant. A crown is then placed on the abutment, fitting perfectly at the edge of the gum.

 

   

   Step 4

   The new tooth is now complete and it is virtually impossible to see       the difference between the existing teeth and the new tooth.


What are the advantages of a single-tooth implant over a bridge?

A dental implant provides several advantages over other tooth replacement options. In addition to looking and functioning like a natural tooth, a dental implant replaces a single tooth without sacrificing the health of neighboring teeth. The other common treatment for the loss of a single tooth, a tooth-supported fixed bridge, requires that adjacent teeth be ground down to support the cemented bridge.

Because a dental implant will replace your tooth root, the bone is better preserved. With a bridge, some of the bone that previously surrounded the tooth begins to resorb (deteriorate). Dental implants integrate with your jawbone, helping to keep the bone healthy and intact.

In the long term, a single implant can be more esthetic and easier to keep clean than a bridge. Gums can recede around a bridge, leaving a visible defect when the metal base or collar of the bridge becomes exposed. Resorbed bone beneath the bridge can lead to an unattractive smile. And, the cement holding the bridge in place can wash out, allowing bacteria to decay the teeth that anchor the bridge.

Multiple Tooth Implants

If you are missing several teeth, implant-supported bridges can replace them. Dental implants will replace both your lost natural teeth and some of the roots.

Step 1

Some people loose teeth in the back of the mouth. This is typically caused by gum infection (periodontitis) or by teeth cracking due to previous fillings.

Between two and four dental implants are installed for a dental implant bridge. This solution does not affect your own teeth. The bridge will function for many years, regardless of the condition of your existing teeth.

Abutments are attached to the dental implants. The next step is to fit a bridge; the new set of teeth is placed on the abutments.

The dental implant bridge is now in place and can withstand the strong chewing forces that occur in the back of the mouth. It feels and functions like natural teeth.

 

What are the advantages of implant-supported bridges over fixed bridges or removable partial dentures?

Dental implants provide several advantages over other teeth replacement options. In addition to looking and functioning like natural teeth, implant-supported bridges replace teeth without support from adjacent natural teeth. Other common treatments for the loss of several teeth, such as fixed bridges or removable partial dentures, are dependent on support from adjacent teeth.

In addition, because implant-supported bridges will replace some of your tooth roots, your bone is better preserved. With a fixed bridge or removable partial denture, the bone that previously surrounded the tooth root may begin to resorb (deteriorate). Dental implants integrate with your jawbone, helping to keep the bone healthy and intact.

In the long term, implants are esthetic, functional and comfortable. Gums and bone can recede around a fixed bridge or removable partial denture, leaving a visible defect. Resorbed bone beneath bridges or removable partial dentures can lead to a collapsed, unattractive smile. The cement holding bridges in place can wash out, allowing bacteria to decay teeth that anchor the bridge. In addition, removable partial dentures can move around in the mouth and reduce your ability to eat certain foods.
