All-on-4 or All-on-6? Full-arch treatment in plain language

What four and six refer to

In simple terms, these approaches use four or six implants to support a complete restoration of one dental arch. The number of implants is not the number of visible replacement teeth. One construction can replace the upper or lower row.

The names help describe a plan but do not determine the right treatment for everyone. Similar offers can involve different preparation, materials and types of restoration.

What the dentist assesses when choosing the number

Bone volume and quality, implant distribution, the bite and restoration design all matter. Planning for the upper jaw differs from planning for the lower jaw. In some situations, additional implants provide other design options or may reduce particular complications.

Avoid reducing the choice to “fewer will always do” or “more is always better”. Ask why a particular option is being recommended for you. If you still have natural teeth, the possibility of preserving them should be assessed first.

Fixed restorations and removable dentures

Implants can support a fixed construction or a denture that you remove yourself. These are different options. A fixed restoration is cleaned in the mouth; a removable denture is taken out as instructed.

Ask to see a model and say: “Will I remove this myself? How will I clean underneath it?” The presence of implants alone does not answer these questions.

What “teeth in a day” may mean

In selected circumstances, a temporary restoration can be planned soon after surgery. This depends on factors such as implant stability and the conditions for treatment. It does not mean that every patient receives the final restoration that day.

The estimate and timetable should distinguish the temporary construction from the final one. Ask about the alternative plan if the implants cannot be loaded quickly on the day of surgery.

Daily cleaning is part of the choice

Before deciding, discuss access around the implants and underneath the restoration. Ask for suitable cleaning tools to be demonstrated and check that you can use them. If you cannot clean the proposed design, discuss the care plan again.

Agree who will provide check-ups and how to report looseness or damage. The fitting appointment completes the restoration, while care and monitoring continue.

Compare the whole plan, not only the number of implants

• Does the estimate cover one arch or both?
• Are planned extractions and bone preparation included?
• What is included in the temporary and final constructions?
• Which material is planned for the restoration?
• How are check-ups, professional cleaning and repairs arranged?
• What alternatives are available?

Take time to understand the proposal

You do not have to choose based on a name or an image online. Ask for a description of the stages, scope and possible changes. Write down anything unclear and discuss it before treatment starts.

The most useful comparison is between two specific plans for your situation, with their benefits, limitations and costs explained.
