Oral Surgeons in Newport Beach & Irvine

To our Patients and Colleagues:

As you are aware, the Covid-19 situation is rapidly changing daily. Guidelines, directives, and orders are being issued from Federal, State and local governments as well as national and regional organizations. Our first responsibility is for our patient and staff safety. We have therefore suspended all elective procedures at both Newport and Irvine locations. This decision was not made lightly, however, we feel a responsibility to play our part in reducing the impact of the spread of the virus.

We are still treating emergencies on a case by case basis and ask that if you or one of your patients is in true need of emergent care to contact our office to arrange for an appointment time.

Thank you.

Dental Implants Newport Beach & Irvine CA

What Are Dental Implants?

A natural tooth consists of a root and a crown. If you compare natural teeth to implant-supported replacement teeth, you’ll see they have the same basic parts. Both have a crown (the visible part used to chew food). Both have a root that holds the tooth securely under the gum and is anchored into the jaw. The difference is that the implant is made of titanium – the same time-tested material used by surgeons for artificial joints. When you lose a tooth, you lose both the root and the crown. To replace the tooth, the surgeon first replaces the root with a small dental implant.

Time is allowed for bone to heal and grow around the dental implant. The bone bonds with the titanium, creating a strong foundation for artificial teeth. A support post (abutment) is then placed on the implant and a new replacement tooth (crown) is placed on top of the abutment. In many cases a temporary replacement tooth can be attached to the implant immediately after it is placed. If all of your teeth are missing, a variety of treatment options are available to support the replacement teeth.

Wisdom Teeth Newport Beach & Irvine CA

What Are Wisdom Teeth?

Third molars are commonly referred to as wisdom teeth. They are usually the last teeth to develop and are located in the back of your mouth, behind your second molars. Their development is usually completed between the middle teenage years and early twenties, a time traditionally associated with the onset of maturity and the attainment of wisdom.

With an oral examination and x-rays of the mouth, Dr. Michaelis, Dr. Jui or Dr. Kriwanek can evaluate the position of the wisdom teeth and predict if there are present or future potential problems. Studies have shown that early evaluation and treatment result in a superior outcome for the patient. Patients are generally first evaluated in the mid-teenage years by their dentist, orthodontist, or by an oral and maxillofacial surgeon.

All outpatient surgery is performed under appropriate anesthesia to maximize patient comfort. Our doctors are trained, licensed, and highly experienced in providing various types of anesthesia for patients.

Call our Newport office at Newport Office Phone Number 949-760-1661 or the Irvine office at Irvine Office Phone Number 949-727-4633 to schedule your wisdom teeth consultation.

Bone Grafting Newport Beach & Irvine CA

Major & Minor Bone Grafting

Missing teeth over a period of time can cause your jaw bone to atrophy, or resorb. This often results in poor quality and quantity of bone suitable for the placement of dental implants as well as long term shifting of remaining teeth and changes to facial structure. Most patients, in these situations, are not candidates for dental implants.

Fortunately, today we have the ability to grow bone where it is needed. This not only gives us the opportunity to place implants of proper length and width, but it also gives us a chance to restore functionality and aesthetic appearance.

Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee). Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum to protect the bone graft, as well as encourage bone regeneration. This is called guided bone regeneration, or guided tissue regeneration.
