All on 4 Dental Implants 

Patients frequently inquire about All On 4 and how it differs from traditional implant procedures. All On 4 is a dental implant method in which only four implants are used to replace the upper or lower set of teeth. These four implants serve as a support system for a new set of fixed teeth to be placed. 

The posterior implants in the All On 4 dental implants process are slanted 45 degrees towards the back of the mouth and put in the anterior maxilla, an area of the jaw with more bone density. In comparison to other implant procedures, the All On 4 approach does not require as much bone density to hold the implant. 

The History Of The All On Four Technique

While the concept of having a full set of teeth supported by only a few implanted teeth was not new, the idea of using a 45° angle for the posterior implants is what gave birth to All On 4. To find out more about cosmetic dentistry visit The Point Dental.

Today, the All On Four procedure is largely regarded as the best alternative for replacing a full arch of teeth. Prof Paulo Malo, meanwhile, has established himself as a world-renowned expert in sophisticated oral rehabilitation. He also developed a number of other approaches to assist patients with difficult restoration treatments. 

Prof Paulo Malo also wrote a number of important books in the subject of restorative dentistry, published several scientific papers, and lectured on oral rehabilitation all over the world. Prof Paulo Malo founded the ‘Malo Clinic Education’ in Lisbon, Portugal, as a result of these accomplishments. He taught other restorative dental professionals who were keen to expand their knowledge of All On 4 dentistry at this location. Our very own dental implant expert, Dr. Theo Spyrakis, has attended the Malo Clinic to expand his knowledge, concepts, and case experience with the All On 4 approach. 

Conventional Dental Implants Vs. All On Four

What is an implant? The dental implant is a small titanium screw that is inserted into the jawbone and then supports a single tooth or a dental bridge. The replacement teeth are linked to the titanium implant, which serves as a basis. A full arch rehabilitation with the traditional dental implant process required 6-8 implants to support a full fixed bridge. 

Only four implants are required to maintain the complete arch when two implants are placed in the front of the mouth and two angled implants are placed in the back. The biggest drawback of the traditional full arch tooth replacement approach is when the posterior implants are screwed into locations with low bone density. The development of the 45° angulated implant allowed for the avoidance of bone-deficient areas of the jaw. Because the All On 4 procedure is less invasive, the healing and rehabilitation time is significantly reduced, and because fewer implant fixings are utilized, there is more freedom in designing and fitting the best replacement teeth. 

Oral Bone Health Issues

Patients with oral bone health difficulties now have a better option with the All On 4 procedure. In the past, a lack of upper jaw bone (typically caused by sinus difficulties or bone loss) was a significant difficulty for implant candidates, necessitating bone grafting to raise the jaw up sufficiently to support the 6-8 implants necessary by traditional procedures. The All On 4 approach, on the other hand, has made a significant effect. This is especially good news for those suffering from osteoporosis or a lack of jaw bone. 

Patients with osteoporosis often believe that because of their low bone quality, they are not candidates for dental implants. That was certainly true in the past. Patients with osteoporosis are frequently able to have the All On 4 surgery since it eliminates the requirement for bone grafting. Patients with significantly resorbed upper jaws are in the same boat. Zygomatic implants are an excellent choice. These lengthier implants are attached to the bottom of the cheekbones through the sinus cavity, eliminating the requirement for the jaw bone to provide support. In most cases, these novel methods can eliminate the need for invasive bone grafting treatments entirely. 

Sleep Dentistry And All On 4

Patients who are afraid of undergoing a surgical dental operation will benefit from sleep dentistry. The use of IV sedation provided and monitored by a skilled and experienced medical specialist is known as sleep dentistry. Intravenously, a special combination of medications is employed to generate a peaceful, tranquil dream-like condition throughout the treatment. 

Can Anything Go Wrong With All On 4?

Without a doubt, one of the most common concerns among patients considering any type of implant operation is what might go wrong. While the All On 4 method has a high success rate, there are several variables to consider when considering dental implant surgery, as with any surgical operation. A dental implant might fail for a variety of reasons, which you can learn more about here. However, there are two more variables to consider while considering the All On 4 procedure: 


Before beginning treatment, our dentist will perform a complete examination to ensure that you have enough bone mass to support the posts. It may be necessary for you to have x-rays or CT scans at this stage in order to obtain the appropriate information. Because of the in-depth planning and work that is done before the young implants are fitted, having all on 4 or 6 dental implants is the treatment that will succeed. We take pleasure in our excellent success record when it comes to dental implant situations. 

  • A model of your teeth or how your teeth used to be made before the procedure and can be improved and adjusted as needed. 
  • As soon as the operation begins, the dentist will make small slits in the gums to allow the titanium posts to be inserted. 
  • At this time, the implant will be placed with a pair of temporary teeth. 
  • Treatment can begin once the dentist is satisfied that the bone has rebuilt, and the sores caused by the incisions have healed. 
  • After 4-6 months, the final prosthesis will be attached. 
  • Dental implants are virtually indistinguishable from natural teeth in terms of both function and appearance.
