A diagram of dental implant at Periodontal Associates. Dental implants are a highly effective solution for lost teeth. Crowns mimic natural teeth in their form and function and titanium posts bond with and stimulate your jaw bone, allowing the implants to act just like a natural tooth would.

Unfortunately, implants can occasionally fail, and if this happens we will need you to come in so we can repair or replace them.

The Structure of an Implant


Most dental implants are made of a titanium post that is embedded in the jaw bone, a ceramic crown that acts as a replacement tooth and an abutment that connects the post and the crown. If one of these parts loosens or breaks, all three can become compromised.

Titanium is usually chosen for implants because it bonds with the jaw bone in a process known as osseointegration. If this process doesn't occur properly then you'll end up with an implant that isn't firmly in place. This will lead to problems later on.

Signs that an Implant May Fail


If the bone doesn't grow around the implant in the right way, mobility is often the primary signal that the implant may fail. This mobility is often very slight at first and usually only a dentist can see it, but as time goes on an implant that hasn't integrated properly can shift when you chew or speak. Implants that have failed completely with frequently.

Other warnings signs of impending failure include pain, inflammation, and infection, but these do not always occur. If Dr. Eshraghi notices that your implant is moving, he may conduct an x-ray to make sure the bone is growing. If the implant is failing, the x-ray may reveal considerable bone loss around the metal area.

Repair and Replacement


In cases where the implant crown becomes cracked or detached, it is an easy matter for us to attach a new, or make any other repairs if necessary. However, if the damage to the implant is too severe, we will need to remove and replace it.

It is easy for us to remove a failed dental implant, but we will need to use a local anesthetic for this procedure. Once the implant is removed Dr. Eshraghi will carefully clean the area. Then we can begin the process of inserting a new implant, making careful note of what went wrong the first time. If there is enough healthy bone in the same area, we won't need a bone graft.

However, in cases of significant bone loss, we may need to place a bone graft to improve the site of the removed implant before placing a new one. Once the bone graft is complete, your mouth may need several months to heal before we can put in a new implant. During the healing period, Dr. Eshraghi may ask you to quit smoking, postpone cancer treatment or make other lifestyle adjustments that will reduce the risk of the next implant failing as well.

Always remember to take good care of your implants by brushing and flossing daily. Also take care to eat a balanced diet and abstain from using your teeth as tools, as this can chip them. If you experience any problems with your implants, contact us right away.

Bone Regeneration for Dental Implants


The jawbone plays an important role in dental health, from providing strong support to the teeth to forming part of the mouth structure - and hence facial appearance. It is thus a cause for concern when your jawbone starts to deteriorate due to bone loss. Fortunately, at Periodontal Associates, we offer several dental solutions, including bone regeneration therapy, which helps to stop bone loss and stimulate the growth of new bone structure. The bone regeneration treatment is especially important when you are considering undergoing dental implant placement.

What Causes Bone Loss?


The loss of bone in the jaw can be due to some reasons. These include:
•  Missing teeth. The jawbone needs constant stimulation to maintain its structure. The stimulation comes from the teeth when you are biting and chewing. Therefore, when you have a missing tooth, your jawbone suffers from insufficient stimulation and thus starts to deteriorate.
•  Advanced gum disease. The jawbone is made up of living cellular tissues, which are prone to bacterial infection. Therefore, the bacterial infection of gum disease can find its way to the jawbone, where it can cause considerable damage.
•  Dental trauma. A traumatic injury to the mouth can knock off the tooth, fracture it, or cause its position on the jaw to shift. All of these can result in an infection, which can easily spread to the jawbone, causing bone loss.
•  Oral infection. An oral infection (viral, bacterial, tumors, and others) can also spread to the jawbone, where it can cause damage and result in bone loss.

The Bone Regeneration Treatment


Bone regeneration is an oral surgery procedure that is performed to stimulate the growth of new bone. It involves placing bone grafting material where the new bone structure will form. The graft then starts to grow, until it completely meshes with the existing jawbone to form one structure.

The bone regeneration procedure is carried out under anesthesia and in a single session. An incision is created on the gum surrounding the area where the loss has occurred to offer access to the jawbone. In case there is an infection, the damaged bone is removed and the area thoroughly cleaned. The graft material is then placed and covered with a biocompatible material. After that, the surgery site is closed by stitching the gums together.

When Is Bone Regeneration Necessary


Bone regeneration is usually performed before a dental implant procedure, when there has been considerable damage to the bone, or when there is not sufficient bone to hold the implants. The procedure can, however, be performed for other reasons such as:
•  Increase the support of the teeth. Bone loss, if left untreated, can reach critical levels that can result in multiple tooth loss. Bone regeneration can thus be performed to increase the support of your teeth.
•  To preserve bone structure and prevent dental problems. Bone regeneration can be used as a preventative treatment, for example, following extraction of the teeth. When used this way, it helps to preserve the jawbone structure by preventing bone loss.
•  To improve facial appearance. Loss of bone in the jaw can lead to an unsightly facial appearance. Regenerating the bone can help to restore proper mouth structure, thus improving the facial appearance.
•  During sinus lift surgery. Sinus lift involves increasing the jawbone structure by lifting the sinus to create more space. A bone grafting material is placed in the created space to allow for the growth of new bone.

Damaged or insufficient jawbone structure can result in you being disqualified for dental implant placement, in addition to causing several dental problems. Periodontal Associates can help to make you ready for implant placement through bone regeneration therapy. Call us today at (971) 317-8414 to book an appointment.
