ALL-ON-4
All-on-4 implant procedure is the result of significant advancements in dental technology and technique. It allows us to restore an entire arch of missing or damaged teeth in a single appointment. Dr. Malkin has used the All-on-4 procedure since 2007.
What are All-on-4 Implants
This technique was developed by Dr. Malo and Nobel Biocare to immediately replace a full arch of teeth without needing bone grafting. It is an alternative to removable dentures. As the name suggests, only four implant posts are needed to support the entire set of fixed teeth. For the sake of comparison, other more conventional methods typically take six to ten implants for fixed implant bridges.
The procedure consists of two phases.
The first phase is the surgery of removing teeth, placing implants, and installing an acrylic implant bridge. It constitutes about 2/3 of the cost. The second phase is 4-6 months later, once implant and gums are fully healed. In the second phase, a permanent implant bridge is fabricated to reflect changes in bone and gums. It can also incorporate desired changes in the appearance of the bridge done at surgery. This final bridge is made from zirconia frame with porcelain over it.
How All-on-4 Implants Work
This procedure uses what is called “tilted implants.” Four posts are placed strategically at a 45-degree angle, to increase strength and stability & to avoid damaging the sinus cavity around the upper jaw as well as the nerve canal in the lower jaw. Because the implants are tilted, they are able to anchor better into the jawbone, improving support. We also use longer implants so that the need for bone grafting is reduced. For the sake of clarification, bone grafting is when the jawbone is supplemented to provide a better base for implants.
Tribeca Advanced Dentistry uses NobelGuide software to plan post placement. Once those posts have been placed, we create a custom fixed bridge to support prosthetic teeth.
All-on-4 Success rate
All-on-4 has been clinically proven to have a very high success rate. Clinical studies published by National Institute of Health have shown 98% percent overall implant success after 3 years for all-on-4 procedure.
All-on-4 Benefits
- More cost-effective than full-set implants: fewer implants and only a single procedure
- More comfortable and convenient than dentures
- Minimally invasive
- Fast – the procedure of extracting teeth, placing implants, and placing crowns done in a single visit
- Greatly reduces the need for bone grafting
- Natural looking
- Long lasting (if cared for properly)
What’s the difference between “Teeth-in-a-day” and “All-on-4”
All-on-4 procedures are one of the several options of “immediate load” (“teeth-in-a-day”) procedure when 4 implants are placed per arch. Depending on your dental needs, we may place more than 4 implants per arch but you will still.
