All-on-4 Dental Implants
All-on-4 uses four implants — typically two upright anteriorly and two angled posteriorly — to support a fixed full-arch bridge, often avoiding grafting where posterior bone is limited. It suits selected patients only; posterior bone, bite forces, opposing dentition and hygiene access all influence whether four implants are appropriate.
Clear definition
What this treatment means
The All-on-4 concept places two implants vertically in the anterior region and two tilted implants distally, so that anchorage is gained in available bone in front of the sinus or the mental nerve loop.
Tilting the posterior implants lengthens the anterior-posterior spread, which reduces the cantilever the prosthesis must carry. That geometric benefit is the actual mechanism, and it is why the arrangement is not simply 'fewer implants'.
It is one option within full-arch treatment, considered alongside All-on-6, segmented bridges and overdentures.
01Problems addressed
- A completely edentulous arch with limited posterior bone
- A failing dentition planned for full clearance
- Denture intolerance where grafting is to be avoided if possible
- Reduced posterior bone height due to sinus pneumatisation or nerve position
02Who may be suitable
- Adequate anterior bone volume and quality for four implants
- Bite forces that the planned prosthesis can withstand
- Good hygiene ability and commitment to maintenance
- Health status that supports implant surgery and healing
03Limitations
- Four implants provide little redundancy — losing one is significant
- Severe anterior resorption may rule the protocol out
- Very heavy bruxism increases mechanical risk with a cantilevered design
- Cantilever length must remain within the limits set by implant spread
- Not every patient is a candidate, and imaging decides
04Alternatives
- All-on-6 where posterior bone permits additional implants
- Implant overdenture where lip support or cleaning favours removability
- Segmented fixed bridges on more implants
- Conventional complete denture
Assessment first
How the diagnosis is established
Records come before recommendations. The required investigations vary with the clinical question.
- CBCT to map anterior bone and the position of the sinus and mental nerve
- Assessment of smile line, lip support and speech
- Records of jaw relationship and the opposing arch
- Evaluation of parafunction and bite force
- Hygiene and dexterity assessment
Treatment journey
A sequenced clinical process
- 01
Planning
CBCT and prosthetic set-up define whether four implants can support the planned arch.
- 02
Extractions and ridge preparation
Failing teeth removed and bone contoured to create restorative space where required.
- 03
Implant placement
Two axial anterior and two tilted posterior implants placed, guided where planning supports it.
- 04
Immediate provisional in suitable cases
A fixed provisional bridge is fitted only where primary stability and occlusal control allow.
- 05
Integration
A protected-function period while the implants integrate.
- 06
Definitive bridge
Verification records, framework trial and delivery of the definitive prosthesis.
- 07
Maintenance
Scheduled removal, cleaning, torque checks and radiographic review.
Prosthetic planning
- Cantilever kept proportionate to the anterior-posterior implant spread
- Multi-unit abutments used to correct angulation and allow screw retrieval
- Convex intaglio to allow cleaning beneath the bridge
- Occlusion refined to distribute load along the implant axis where possible
Materials considered
- Titanium implants and multi-unit abutments
- Reinforced acrylic provisional bridge
- Titanium-reinforced hybrid or monolithic zirconia definitive bridge
Informed decisions
Benefits, risks and maintenance
Possible benefits
- Grafting can often be avoided where posterior bone is limited
- Fewer surgical sites than a six or eight implant arrangement
- Fixed teeth without palatal coverage in most upper designs
- A fixed provisional in suitable cases shortens the period of removable wear
Risks and complications
- Loss of one implant materially affects support for the whole bridge
- Prosthesis and screw complications, especially distal to the last implant
- Peri-implant disease where cleaning access is not maintained
- Fracture of veneering material or acrylic teeth
Typical duration
Surgery is usually a single session per arch; the definitive bridge typically follows around four to six months later.
Recovery and adaptation
- Swelling and bruising for up to a week after extractions and placement
- Strict soft diet where an immediate provisional is fitted
- Several short review appointments in the first month
Long-term maintenance
- Daily cleaning under the bridge without exception
- Professional bridge removal and cleaning at set intervals
- Periodic torque checks and component replacement
- Bone-level radiographs at review
What affects cost
- Four implants plus multi-unit abutments
- Extractions and ridge contouring
- Immediate provisional prosthesis
- Definitive material choice
- Number of arches treated

Connected Clinical NodeBone Grafting Before Dental Implants
Bone grafting increases or preserves bone where an implant cannot be placed in a prosthetically useful position with adequate support. The graft type and timing depend on defect size, anatomy, soft tissue, general health and the proposed implant restoration.
Connected Clinical NodeAll-on-6 dental implants
A six-implant full-arch protocol chosen when bone volume and load distribution favour additional support.
Connected Clinical NodeFixed Full-Arch Implant Teeth
A fixed full-arch implant prosthesis replaces all teeth in one jaw using several implants. Planning must coordinate bone, implant distribution, lip support, speech, the bite, hygiene space, temporary teeth and the definitive prosthetic material.
Connected Clinical NodeImmediate Fixed Teeth on Implants
Immediate fixed teeth are temporary implant-supported teeth fitted soon after surgery in suitable cases. They require adequate implant stability, controlled bite forces and a design that protects healing; definitive teeth are made after biological and functional review.
Connected Clinical NodeZirconia Full-Arch Implant Bridge
A zirconia full-arch bridge is a rigid ceramic implant prosthesis designed for strength, colour stability and a natural surface. Suitability depends on restorative space, implant position, the opposing teeth, bite forces, repair strategy and hygiene access.
