All-on-4 vs All-on-6 vs 3-on-6: How They Differ

Full-arch implant treatment is individualized. Implant number and prosthetic design are selected after evaluating bone, bite, remaining teeth, gum health and restorative goals.

All-on-4, All-on-6 and 3-on-6 are different ways to restore a full dental arch with implants. They are not interchangeable and one is not automatically better for every patient. The choice depends on bone volume, implant position, bite forces, gum health, remaining teeth, hygiene access and the prosthetic design needed for long-term function.

International Dental Center PV evaluates these full-arch options in Puerto Vallarta, Jalisco, Mexico. Existing X-rays or CBCT images can help with a preliminary review before travel, but the final diagnosis and treatment plan require clinical evaluation.

What is All-on-4?

All-on-4 uses four dental implants to support a fixed full-arch restoration. It may be considered when four well-positioned implants can provide the support needed for the planned prosthesis. Bone anatomy, implant stability, bite and restorative space must be assessed before deciding whether this approach is appropriate.

See the detailed All-on-4 dental implants page for treatment stages, travel planning and current clinical information.

What is All-on-6?

All-on-6 uses six dental implants to support a fixed full-arch restoration. The additional implant positions may be useful in selected cases, but six implants do not automatically make a treatment superior. Adequate bone, implant distribution, prosthetic design and the patient's bite remain important factors.

See the detailed All-on-6 dental implants page for candidacy, stages and restorative planning.

What is 3-on-6?

3-on-6 uses six implants per treated arch to support three separate fixed bridges. Its prosthetic design differs from a connected All-on-4 or All-on-6 restoration. This can change hygiene access, maintenance and how the restoration is planned, but candidacy still depends on bone, gums, bite and implant position.

See the detailed 3-on-6 dental implants page for the surgical and restorative phases.

How are All-on-4, All-on-6 and 3-on-6 different?

The main differences are the number and distribution of implants and the design of the final prosthesis. All-on-4 generally uses four implants with a connected full-arch restoration. All-on-6 generally uses six implants with a connected full-arch restoration. 3-on-6 uses six implants supporting three separate bridges.

The treatment decision should not be based only on implant count or marketing labels. A clinician must evaluate bone volume and quality, existing teeth, gum condition, occlusion, parafunctional habits such as grinding, restorative space, hygiene access and the patient's functional and aesthetic goals.

Does one option last longer than the others?

There is no universal answer. Long-term performance depends on diagnosis, implant integration, prosthetic design, bite, oral hygiene, maintenance, smoking and general health. A greater number of implants does not by itself guarantee a better result.

How many trips to Puerto Vallarta may be needed?

Full-arch implant treatment is commonly completed in phases. Surgery and the definitive restoration are often separated by a healing period, and the number of trips depends on extractions, grafting, implant stability, temporary restorations and the individual prosthetic plan. The clinic should confirm your schedule before you book travel.

How do I know which treatment is right for me?

The most useful first step is a diagnostic review rather than choosing a treatment name on your own. Send available dental records, panoramic X-rays or CBCT images for preliminary planning when possible. Dr. Alberto Hernández and the clinical team can then discuss which options may fit your case; the final recommendation follows an in-person examination and appropriate imaging.
