Advantages of All-On-4

How we can give you the highest quality dentures in the shortest amount of time - without bone grafts!

The All-on-4 Procedure was developed to help patients without teeth rapidly regain a fully-functional mouth and jaw.  It is a procedure that uses the fewest implants possible, avoids bone graft surgery, and provides high-quality restorative results in the shortest time possible.

The All-on-4 Dental Implant Procedure uses four implants, with the back implants placed at an angle to take maximum advantage of existing bone.  With our skilled Oral Surgeon and Prosthodontist, this can be done quickly and easily, so that you can leave the same day with fixed, non-removable replacement teeth.

Traditional approaches to restoring a full arch of teeth usually involved bone grafts, six or more implants, and as many as 18 months of treatment. That meant that a patient often would be without any teeth, or with ill-fitting temporary dentures for more than a year.

With the All-on-4 Dental Implant Procedure, you have two or four consultation visits to the office, to allow the Oral Surgeon and  Prosthodontist to gather information for a treatment plan (e.g., CAT Scan, X-rays, impressions, photos). Following your consultation, you are scheduled for placement of the implants and the new teeth are fitted and adjusted, all in one appointment (even when extractions are necessary).

Our All-on-4 patients come to the office in the morning with unhealthy (or no) teeth, and leave in the afternoon with a beautiful set of fixed, functional teeth!

After almost six months, when the gums have fully healed and the implants are fused to the natural bone, our Prosthodontist will take new impressions of your mouth and prepare a final, stronger, permanent set of teeth adjusted to a perfect fit this is all included in the initial fee. This helps ensure that your new teeth will last for decades, and provide maximum support, beauty, and function.


How are All-On-4 Dental Implants different from dentures?

As opposed to dentures, All-On-4 dental implants are a permanent set of teeth that look and feel natural, which means they:

  • Are permanent teeth that are brushed and cleaned like natural teeth
  • Do not have to be taken out and cleaned each night
  • Do not need messy, sticky adhesives
  • Do not press down on your gums, preventing discomfort
  • Allow for you to taste and experience the hot/cold of your food
  • Do not cause you to gag
  • Allow you to bite with increased force, which means you can eat all of your favorite foods
  • Prevent bone deterioration

How do All-On-4 Dental Implants compare to traditional implants?

All-On-4 Dental Implant procedures utilize only 4 implants, whereas traditional implants utilize anywhere from 5 to 8 implants in one arch. Because the posterior implants of the All-On-4 procedure are placed at an angle, it allows for increased support by using the natural support of your bone.

Also, traditional implants often require bone grafting, a process that can take 6 months or more. The All-On-4 Dental protocol requires no bone grafting for most patients, with a success rate that is equal to or better than traditional implants.

All-On-4 Dental Implants save you from unnecessary surgery and discomfort, as well as time and money.

What makes Dr. Zarrinkelk qualified to perform All-On-4 procedures?

Dr. Zarrinkelk has performed dental implant procedures since the 1990s and has become a leader in the Ventura area because of his expertise in the field. He has studied under the pioneer of the All-On-4 protocol, Dr. Paulo Malo.

Every patient is different and can be complex due to health issues and unique bone conditions. But, Dr. Zarrinkelk has seen it all and can provide each patient with a solution that will be safe and effective for them.

Furthermore, Oral & Maxillofacial Surgery of San Buenaventura is fully equipped with imaging equipment, an on-site lab and an experienced team to provide you with the best care possible.

How many All-On-4 Dental Implant Procedures has Dr. Zarrinkelk performed?

Dr. Zarrinkelk has been performing dental implant procedures for over 12 years. The All-On-4 protocol was pioneered in Europe. Published papers began appearing around 1994. At the time, it seemed a radical concept defying many long held beliefs. Dr. Zarrinkelk was immediately intrigued by the concept, though skeptical, and began following the literature.

What is his success rate with All-On-4 Dental Implants?

Published studies show a 98.2% success rate using All-On-4 Dental Implants on the lower arch, and a 97 - 98% success rate using them on the upper arch.

Who is the ideal candidate for All-On-4 Dental Implants?

The ideal candidate for the All-On-4 Dental Implant procedure is someone who is currently wearing dentures or will need dentures in the future and is in good health with little bone deterioration.

If you or Dr. Zarrinkelk are concerned about any health issues, he will contact your physician to discuss your medical condition and determine if this procedure is right for you. Dr. Zarrinkelk will obtain medical clearance from your doctor, if your doctor feels that it is acceptable to proceed with the procedure. It is rare for a medical condition to interfere with your ability to have this procedure. However, because of his expertise, Dr. Zarrinkelk has been able to work with all types of bone conditions and those who might have been turned away from other dentists. In this instance, Dr. Zarrinkelk may arrange to have to place additional implants to counteract the bone loss or perhaps help you to grow more bone, but no matter what, Dr. Zarrinkelk  will personally evaluate your case to provide you with the best possible results.

If Dr. Zarrinkelk feels that you are not a good candidate for All-On-4 Dental Implants because of health concerns or severe bone loss, don't worry; Dr. Zarrinkelk is an expert in all types of dental implants. There are always alternative procedures to meet your needs.

Where will my replacement teeth be made?

Your brand new smile is crafted in our on-site lab. Dr. Zarrinkelk personally oversees each step to ensure the best results possible.

Will my results look natural?

Dr. Zarrinkelk uses the latest concepts in smile design to create your new smile.  Dr. Zarrinkelk takes your facial features, skin tone, age, and personality into consideration when creating your new permanent set of teeth to ensure that they are congruent with your features. It is important that they are the right size, shape, color, and proportion. A common mistake made by dentists inexperienced with the subtleties of the prosthetic demands, is to show a line, when smiling, where the artificial gums meet your natural gums. This is evaluated by Dr. Zarrinkelk during the surgical planning to ensure that this junction is not visible during smiling or speech and you have the most natural outcome possible.

Prior to the fabrication of your final set of new teeth, our Prosthodontist makes sure that you are pleased with the size, shape, color, proportion, and comfort of your new teeth. Many patients comment that their new teeth are more beautiful than their permanent teeth ever were. You can be confident in your new smile.

From beginning to end, what should I expect with my All-On-4 Dental Implant procedure?

Each patient is different, and therefore, can expect different timelines, but a general guideline for the All-On-4 Dental Implant Procedure is:

  • 1-2 visits for initial consultation and to prepare x-rays and impressions
  • 1 visit to place the implants and new teeth and extract any teeth (if necessary)
  • Come back for post op visits as required usually 2
  • 1 visit four months after placing implants for new impressions for the permanent set of teeth
  • 1 visit six months after placing implants to place permanent set of teeth

Why don't I get my permanent set of teeth the day my implants are placed?

As with any surgery, you need time to heal. So, once the implants are placed, you are given a temporary set of teeth or long-term provisional prosthesis made of acrylic resin, which places less stress on your gums and implants. With this set of teeth, you take it easy. You can eat solid foods, but we ask you to only eat foods that can be cut with a fork or that you do not have to tear with your front teeth (like apples).

Once your gums have healed and the implants have stabilized, our Prosthodontist will place your permanent set of teeth, which will be made of acrylic or porcelain and will have a titanium frame that allows you to enjoy all of your favorite foods.

What if I just need implants on my bottom arch? What do I need to do to have All-On-4 Dental Implants on both arches?

It is perfectly fine to have All-On-4 Dental Implants on only the lower or upper arch. However, if you feel you might need dentures on both eventually, it is typically best to perform the procedure at the same time to achieve better results, and save you time and money. But in certain cases, we can schedule separate procedures to meet your financial and health needs.

What to Expect During Your All-On-4 Dental Implant Procedure

You could have a brand new smile in one day, with All-On-4 Dental Implant Procedure.

While every patient is different, here is a general guideline of what to expect during your All-On-4 Dental Implant Procedure.

The first thing to remember when getting All-On-4 Dental Implants is not to worry. Dr. Zarrinkelk and his team are highly skilled with dental implant procedures and strive to make this a positive and easy experience for you.

Before Your Dental Implant Procedure

Before the procedure, Dr. Zarrinkelk will take X-rays or a 3D CAT SCAN, if needed, and perform a brief exam to determine if you are a candidate for dental implants and the recommended treatment. If you are a candidate for All-on-4 dental implants, Dr. Zarrinkelk will then thoroughly explain the procedure, answer any questions and address concerns you may have. Your appointment will be made to place your implants and new teeth.

During Your Dental Implant Procedure

When you arrive to your appointment, you will be greeted by our friendly and knowledgeable staff. Once you are placed in your surgical suite, your conscious sedation will begin. After your sedation has taken effect, your procedure will begin by extracting any remaining teeth and preparing your mouth for the implants. Dr. Zarrinkelk will place the implants, the first step to your new smile. After the implants have been placed, our Prosthodontist will begin the fabrication of your new teeth.

Once your new set of teeth is placed, Dr. Zarrinkelk will check your bite and ensure accuracy of the placement. At this time, you will be able to look in the mirror and admire your beautiful new smile. This is an emotionally rewarding experience that often brings tears to our patients' eyes and ours as well.

After Your Dental Implant Procedure

Dr. Zarrinkelk will review your post-procedure care with you and discuss what will be coming up in your future follow-up appointments. Recovery is minimal and you may even be able to return to work the next day. In about six months, after the dental implants have fully integrated with the bone, it will be time to remove your temporary set of teeth and place your new set of permanent teeth. This is extremely easy and virtually painless; requiring only the removal of four discreetly placed screws. If any alterations from the initial, temporary teeth are required, they will be discussed and planned at this time.
