When a dental arch is severely compromised — complete edentulism, remaining teeth too damaged to save, or removable dentures that have become uncomfortable and functionally insufficient — All-on-4 and All-on-6 full-arch implant rehabilitation represents today's most documented and durable solution.
The principle shared by both protocols is straightforward: rather than placing one implant per missing tooth (which would require 12 to 16 implants per arch), a reduced number of strategically positioned implants support a complete fixed prosthesis carrying 10 to 14 teeth. This concept, developed from the work of Dr. Paulo Maló in the early 2000s, is now one of the most studied implant protocols in the world.
All-on-4 — when bone is limited: The All-on-4 protocol relies on tilting the two posterior implants (up to 45°), anchoring them into the dense cortical bone of the anterior jaw region, generally better preserved than posterior bone after tooth loss. This strategy avoids bone grafting or sinus lifting in the vast majority of cases, significantly shortening overall treatment time. All-on-4 is particularly suited to patients with moderate to severe bone atrophy.
All-on-6 — when bone volume permits: The All-on-6 protocol adds two implants in the premolar region, distributing occlusal forces across six anchor points rather than four. All-on-6 is preferred for patients with sufficient bone volume, high masticatory force, or those who wish to maximize the long-term durability of their rehabilitation.
Immediate loading is one of the most important features of these protocols. In the vast majority of cases, a fixed provisional prosthesis is placed on the day of surgery itself. The patient leaves with a functional, aesthetic arch at the end of the procedure, without going through a removable denture phase. The definitive prosthesis — typically monolithic zirconia or resin reinforced on a titanium framework — is fabricated after the osseointegration period, 3 to 6 months post-surgery.
Digital planning is central to a modern implantology approach. 3D CBCT analysis precisely models bone anatomy, nerve and sinus positions, and determines optimal implant positioning before any procedure.
Procedures we offer
All-on-4 (4 implants, immediate loading)
Two axial implants in the front and two angled at 30–45° in the posterior region. Often avoids grafting. Fixed provisional prosthesis placed the same day.
All-on-6 (6 implants, optimal distribution)
Six implants evenly distributed, including two in the premolar regions. Better force distribution. Indicated when bone volume is sufficient.
Immediate loading (teeth in a day)
Fixed provisional prosthesis placed day of surgery. Definitive prosthesis fabricated after osseointegration (3 to 6 months).
Lower jaw and upper jaw rehabilitation
Treatment of both arches in the same surgical session. Reduces visits and optimizes occlusal coordination.
