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 Dental 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 Dental Implants, contact us right away.

Implant-Supported & Hybrid Dentures

Current studies show that about 35 million people in America are in this condition. In previous years, dentists would usually extract the rest of their teeth and then make dentures for them.

But dentures have a variety of problems. For instance, they need adhesives to stay in place, without which they can slip and even fall out. Speaking and eating while wearing them is often uncomfortable.

Another option is to put dental implants in for each missing tooth, but installing that many dental implants is expensive. A better alternative is to place implants in strategic locations in the mouth and use them to support a hybrid denture.

What are Implant-Supported Dentures?


Implant-supported dentures, also known as overdentures or hybrid dentures, are supported by dental implants that are beneath the gum line. We need at least four implants to place the overdentures, but we can hold them in place even better if we use more.

What is the Procedure for Implant-Supported Dentures?


Once we place the implants, we need to give your jaw bone time to fuse with them. The implant posts we place in the jaw are made of titanium, which is a metal that will naturally fuse with the bone in a process called osseointegration. Once osseointegration is complete, the posts will stimulate and rejuvenate the jaw bone just like natural tooth roots.

Once the posts have bonded with the jaw bone, we will place a bar made of gold or titanium to hold the new prosthetic teeth in place. This makes the prosthetic much more secure than dentures that sit on the gums with adhesive. Dr. Eshraghi will then fix the denture in place. Unlike traditional dentures, they are attached to the dental implants embedded in the jaw bone and are thus irremovable.

What are the Advantages of Implant-Supported Dentures?


The biggest asset of hybrid dentures is that they restore your ability to eat, speak, and smile normally and comfortably. They are also considerably more affordable than a getting multiple dental implants. It is also easy to clean the implant denture because you brush it just like you would your normal teeth instead of taking it out.

Candidates for Implant-Supported Dentures


Many people who have an entire arch of missing teeth are candidates for implant-supported dentures. The main requirement is that you must have adequate oral health and overall health. A consultation with Dr. Eshraghi, in which he’ll go over your medical history will determine whether or not you qualify.

Implant-Retained Dentures


Implant-retained dentures are similar to implant-supported dentures, except that they are removable. Implant-retained dentures will still absorb most of the force when you bite and the implants supporting them will retain them. However, the idea of having removable teeth doesn’t sit well with many of our patients because it reminds them of their tooth loss. Having teeth in their mouth 24/7 makes them feel much better, so we usually recommend a more permanent and better supported treatment option.
