Four strategically distributed implants can support a fixed full-arch restoration. Suitability depends on bone anatomy, any maintainable natural teeth and the long-term prosthetic plan.
All-on-4 is a treatment approach in which a fixed restoration for one complete arch is supported by four implants placed in suitable positions. It does not mean that each missing tooth needs its own implant.
Dr. Ali İlker Baştan first assesses whether existing natural teeth can be maintained. Three-dimensional imaging, available bone, gum health, bite, medical history and access for cleaning are considered alongside the prosthetic design. If four implants cannot provide suitable distribution, a different configuration may be discussed.

Suitability
Who May Be Considered for All-on-4?
01
A Missing Full Arch
If all teeth in one jaw are missing, fixed and removable restoration options can be reviewed.
02
Remaining Teeth
Teeth with a maintainable long-term prognosis are assessed before any extraction decision.
03
Bone and Bite
Suitable implant positions, chewing forces and restorative space influence the treatment plan.
Treatment Journey
How Is All-on-4 Planned?
The schedule, any extractions or bone procedures and prosthetic design vary between patients.
01
Clinical Assessment
Medical history, remaining teeth and imaging are reviewed; possible alternatives are discussed.
02
Surgical and Prosthetic Plan
Implant positions and the temporary and final restorations are planned together.
03
Implant Placement
The planned implants are placed. A fixed temporary restoration may be considered if initial stability is sufficient.
04
Healing and Follow-Up
Healing is monitored, the final restoration is completed and a maintenance schedule is agreed.
All-on-4 uses four implants and All-on-6 uses six to support a full-arch restoration. A larger number is not inherently better; additional implants need to contribute support from favourable positions.
The assessment considers implant distribution, any unsupported posterior extension, grinding, the opposing arch and access for daily cleaning. Different configurations may be appropriate in the two jaws.
Individual suitability requires clinical assessment and imaging.
