All-on-4 is an approach in which four implants support a full-arch prosthesis in one jaw. The number refers to an individual treated arch, not necessarily the whole mouth. Whether remaining teeth can be preserved, bone anatomy and access for cleaning matter as much as implant number.

What is assessed before treatment?
The remaining teeth, bone volume and nearby nerves or sinuses are assessed. Jaw relationships, visible tissues, speech and the space needed for a prosthesis influence the design. Difficulty with a removable denture alone does not establish fitness for implant surgery.
How is treatment planned?
Implant positions are selected around the restorative plan; angled placement may be considered where appropriate. The timing of temporary teeth depends on initial stability and other clinical conditions. The final prosthesis is assessed after healing reviews. Same-day fixed teeth cannot be promised to every patient.
Alternatives and limitations
Alternatives can include fixed restorations supported by more implants, implant-retained removable dentures or conventional dentures. All-on-4 does not eliminate the need for grafting in every case. Other implant approaches can also support several replacement teeth with a bridge rather than one implant per tooth.
Risks and follow-up
Alongside surgical risks, maintenance issues can include prosthesis fracture, loose screws and difficulty cleaning. Patients need instruction on cleaning beneath the restoration. Fixed does not mean maintenance-free; a clinician may remove the prosthesis when necessary. Pain, movement or inaccessible areas require review.

Frequently Asked Questions
Does All-on-4 always avoid a period without fixed teeth?
Temporary options and timing are discussed in advance. A fixed temporary prosthesis on the day of surgery is not possible for everyone.
How does All-on-4 differ from All-on-6?
They use four or six implants respectively to support an arch. The appropriate number depends on bone and restorative planning.
Can the patient remove the fixed prosthesis?
It is not intended for daily removal by the patient. Clinical removal may be required for maintenance or repair.
