All-on-4 & All-on-6 Systems

10 October 2026
In brief

All-on-4 and All-on-6 describe full-arch restorations supported by four or six implants. The number and position of implants must be selected for the individual jaw and treatment plan.

These systems may be considered when most or all teeth in one jaw are missing or cannot be predictably maintained. The name describes a treatment concept rather than a guaranteed result. Bone condition, implant stability, bite, hygiene access and the design of the temporary and final restoration all affect planning.

Who may be assessed?

A full examination is required to review the teeth, gums, jawbone, smile line, bite, medical history and expectations. Existing infections and gum disease may need treatment first. Four or six implants will not be suitable for every jaw.

Planning and treatment

Planning may include three-dimensional imaging and digital records. Treatment can involve removing teeth, placing implants and providing a temporary restoration, followed by a final restoration after healing. Immediate loading is only considered when clinical conditions provide sufficient stability.

Risks and alternatives

Surgical and implant-related risks include infection, delayed healing, implant failure and injury to nearby structures. Prosthetic complications may include screw loosening, wear, fracture or difficulty cleaning. Alternatives can include a removable denture, an implant-retained overdenture or a different implant distribution.

Cleaning and follow-up

A full-arch restoration requires daily cleaning around the implants and beneath the prosthesis using techniques demonstrated by the dental team. Professional maintenance and periodic checks of the bite, screws, components, gums and bone are part of long-term care.

Individual assessment

A starting point for a conversation with a qualified dentist. Every treatment begins with an individual assessment.
