What is All-on-4?
All-on-4 is a full-arch implant concept that uses four implants to support a fixed or planned full-arch restoration in selected cases.
FULL-ARCH IMPLANTS • PUNE
All-on-4 and All-on-6 are full-arch implant treatment concepts. The appropriate design depends on the available bone, implant positioning, anatomy, restorative plan, oral health and the clinical objectives of the patient.
Use the comparison to understand the main differences, then discuss the options that fit your clinical findings and treatment goals.

QUICK ANSWERS
All-on-4 is a full-arch implant concept that uses four implants to support a fixed or planned full-arch restoration in selected cases.
All-on-6 uses six implants to support a full-arch restoration when the clinical plan calls for that configuration and the patient is suitable.
Not automatically. More implants are not universally better; the appropriate number depends on anatomy, bone, restorative requirements and the clinician’s treatment plan.
The decision requires examination and appropriate imaging, followed by assessment of bone, gums, bite, restorative space, hygiene, medical factors and treatment goals.
SIDE-BY-SIDE
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Implant configuration | Four implants supporting a full-arch restoration in selected cases. | Six implants supporting a full-arch restoration in selected cases. |
| Planning | Depends on bone, anatomy, implant positions and restorative design. | Same core planning principles, with a six-implant configuration where appropriate. |
| Suitability | Individual assessment is required. | Individual assessment is required. |
| Cost | Depends on the complete treatment plan, components and laboratory work. | May differ because the implant count and overall plan differ. |
| Long-term care | Requires professional follow-up and careful home hygiene. | Requires professional follow-up and careful home hygiene. |
CLINICAL DECISION
There is no universal winner. The appropriate option depends on diagnosis, anatomy, oral health, treatment goals, expected maintenance and the clinician’s assessment. A consultation is the right next step if you are deciding between these options.
