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.

Dr. Malloy at Periodontal Associates

Dr. Kyle Malloy


Dr. Malloy grew up in an Air Force family which allowed him to live all across the country and abroad. He considers the PNW to be his home after living here the past 20+ years. His father was a Prosthodontist in the Air Force and later became the Director of Clinical Restorative Dentistry at the Oregon Health & Science University School of Dentistry. While growing up, Dr. Malloy shadowed his father and began to understand the art and science of dentistry at an early age and in high school started working in the dental lab at OHSU. This was where Dr. Malloy first developed an appreciation for dentistry as a profession.

Dr. Malloy attended Gonzaga University for his undergraduate education and then continued his education as a dental student at OHSU. As a dental student he was involved in student government, active in research, was the President of the Student Research Group, and received numerous scholarships and awards. He presented multiple research projects at national meetings across the country and received the award of Best Clinical Presentation at the prestigious Hinman Student Research Symposium for his research on CAD-CAM milling applications in dentistry.

Dr. Malloy graduated with Great Honors and received awards in Oral Surgery, Implant Dentistry, Operative Dentistry and Dental Material Research after being selected by the faculty as the top student in each category. Following graduation, Dr. Malloy elected to pursue further surgical training in Periodontics and Implant Surgery at OHSU.

During his additional three year residency, Dr. Malloy focused heavily on soft tissue grafting and dental implant surgery and restorations. Part of his training included rotations at the VA Dental Clinic treating medically complex patients in a hospital setting and at the main OHSU hospital with the anesthesiology department. Dr. Malloy received his certificate in Periodontology and his master's degree (MS). His research on digital radiography and dental implants was selected to be presented at the Academy of Osseointegration's annual meeting.

Dr. Malloy is a Diplomate of the American Board of Periodontology and is Board Certified in Periodontal and Implant Surgery. This is an achievement awarded to only a percentage of periodontists who successfully challenge the Board by completing the two year process involving both computer based and live oral examinations. Dr. Malloy continues to be involved in continuing education and study clubs and actively lectures on topics ranging from soft tissue grafting to dental implant surgery to full mouth implant reconstructions.

Dr. Malloy is a member of the Academy of Osseointegration (AO), American Academy of Periodontology (AAP), Oregon Society of Periodontists (as well as an active board member), American Dental Association (ADA), Oregon Dental Association, (ODA), Multnomah Dental Society (MDS), OHSU School of Dentistry Alumni Association (as well as an active board member), and American Board of Periodontology (ABP).

When Dr. Malloy is not treating his patients or lecturing, he can be found spending time with his wife, Katie, and their two young sons. He enjoys cooking and camping with his family, watching sports (especially Gonzaga Basketball), and relaxing at the beach or on the golf course.
