Implant manufacturer Nobel Biocare was among the first to identify the evolution of the All-on-4 technique as a potential valid and cost-effective alternative to conventional implant techniques, and funded studies by Portuguese dentist Paulo Maló to determine the efficacy of this approach. During this time this technique was also used by various other clinicians around the world.

All-on-4 is not an invention, but rather a treatment technique that has evolved over time and has the following features:

• four dental implants to support a full fixed bridge (documented since 1977)
• the use of angulated implants in the back to overcome bony deficiencies or anatomical structures (documented since 1990)
• immediate loading (documented since 1990)

The concept itself of the total rehabilitation of a full set of teeth supported by as few as four fixtures was not a new one. Professor P-I Branemark,who discovered osseointegration, published numerous articles in the 70s with successful rehabilitation of a full arch supported by this number of fixtures. However, it was the angulation of the back implants that led to today's All-on-4, and has been trialed by numerous clinicians simultaneously in the USA, Sweden, Portugal, and South America in the 1990s. The technique evolved when in an attempt to avoid certain anatomical limitations typically seen in the back of the upper and lower jaws have, clinicians successfully avoided bone-deficient areas with the use of angulated implants. Anatomical limitations are more prevalent in patients with full dentures, and once the back implants are placed at an angle there is often only enough room left for two more implants in the front. This has led to the use of only four fixtures to support a full set of teeth.

The benefits of All-on-4 implants include:

• Full-arch restoration
• Shorter installation times than other implants
• Prevents further bone loss
• Decreases the need for a bone graft

Dental Veneers

Dental veneer is a thin layer of material placed on the front surface of a tooth in order to improve esthetics and ultimately create a “perfect smile”. Veneer can be made of either resin or ceramic. Many defects can be corrected by dental veneer – namely;

• Too close gaps or small spaces
• Minor tooth rotation or misalignment
• Discoloration
• Tooth lengthening and/or shape modification

Interestingly, perfect shape, color and alignment of front teeth can easily be achieved with dental veneers thanks to its fast, safe and innovative technology. Only minimal tooth preparation (0.3-0.5 mm) is required in order to gain space for veneers.

With maximum esthetic concerns in veneers cases, thorough examination and detailed discussion with the patient are utmost important in order to meet possible expectations and eventually achieve highest satisfying results.


Tooth whitening
(also known as tooth bleaching) is a procedure that brightens natural vital tooth structure from the inside(dentin). Therefore, the color of dental fillings or prostheses cannot be changed with this procedure. This can be performed using peroxide gel topically without grinding away any tooth structure. The only expected complication is transient mild to moderate sensitivity which varies among each individual. Nevertheless, since tooth whitening has gained more popularity nowadays, newer generations of bleaching materials have been proposed in the market. These improved versions are claimed to be more effective and cause less sensitivity.
