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.

Ridge Augmentation


Before Getting Dental Implants


To prevent failure, dental implants need to be inserted in a healthy and strong jawbone that has sufficient space. Therefore, having ridge deformities can present a huge challenge when inserting dental implants due to insufficient or weakened bone structure. On top of that, ridge deformities can present aesthetic problems by altering your facial appearance. Ridge deformities are, however, treatable using ridge augmentation, a dental procedure that you can receive at Periodontal Associates.

What is Ridge Augmentation?


Ridge augmentation is an oral surgery procedure that is performed to fix various deformities of the jaws. The procedure aims to restore the perfect ridge structure - by improving the shape and size of the alveolar ridges. It involves the use of bone grafting to generate bone tissue in the area where the deformities are located.

Depending on the type of dental situation involved, ridge augmentation can be focused only on a tooth socket(s) or involving a large section (or the entirety) of the ridge.
•  Ridge augmentation involving tooth sockets. Also known as localized ridge augmentation, this procedure is carried out after extracting a tooth/teeth. It involves placing a bone graft material inside the tooth socket, thus allowing it to fill up with new bone tissue that meshes with the existing jawbone
•  Entire ridge augmentation. This procedure is performed when a large or entire section of the ridge has been affected by a ridge deformity. The bone graft material is placed in the area where the new bone tissue is needed. It then grows and meshes with the remaining jawbone.

What Causes Ridge Deformities?


Ridge deformities requiring ridge augmentation can be caused by some reasons. Below are the most common ones:
•  Dental trauma. A traumatic dental injury can cause damage to the jawbone, and if the damage is not fixed, it can result in the deterioration of the bone structure.
•  Improperly healed tooth socket following extraction. During a tooth extraction, the bone structure surrounding the tooth socket can be damaged. The damage can cause the socket not to heal properly, which can then start the deterioration of the ridge.
•  Developmental deformities. Some ridge deformities are developed, right from birth or acquired as one is growing up. Still, these deformities can cause significant damage to the structure of the jaws, thus requiring ridge augmentation to fix them.
•  Periodontal disease. Advanced gum disease can spread to the jawbone, where it can infect the bone structure leading to deterioration.
•  Missing teeth. Aside from the damage caused to the jawbone during extraction, missing teeth can also cause bone loss by removing the stimulation that is needed for proper growth and maintenance of the jawbone.

How is a Ridge Augmentation Procedure Performed?


The ridge augmentation procedure is a simple procedure that is carried out in a single visit. On the day of the procedure, you are placed under anesthesia (which can also be combined with sedation) to relax you and ensure that you do not feel pain. An incision is then made in the gums, around the area where the deformity is. A bone grafting material is placed along the ridge, or in the case of localized augmentation, inside the tooth socket. The wound is then closed up by stitching together the surrounding gum tissue.

For the tooth socket regeneration, the procedure is usually carried out immediately after tooth extraction. This helps to prevent the need for a second surgery down the line.

At Periodontal Associates, we help to prepare you for the dental implant procedure by using ridge augmentation to restore or maintain a perfect jawbone structure. Get in touch with us today at (971) 317-8414 for any questions you might have about the procedure.
