But what are all-on-4 dental implants?
The all-on-4 dental implant is a technique that replaces the missing teeth with a bridge or a denture using four titanium posts in each jaw.
This article discusses the procedure, cost, and complications of all-on-4 implants.
All-on-4 Dental Implants
The All-on-4 dental implant system is a modern option for a full mouth restoration process using only four implants to retain a full prosthesis.
It provides esthetics and functions just like natural teeth.

Together with his colleagues, Paulo Malo, a dentist, developed this concept in 2003 and collaborated with Nobel Biocare, one of the leading implant companies in the world. 
They restored a full-arch using only four titanium implant posts by placing two posts vertically in front and two tilted posts in the back.
These four posts can support an entire arch of 12 to 14 teeth.
Difference Between All-on-4 & Conventional Implants
The most significant difference between these two is that conventional procedures require several surgeries and prolonged healing time.
The all-on-4 is an improved technology of traditional implants. It can replace natural teeth with only four titanium posts per arch.
Difference between the all-on-4 and conventional implants
Properties All-on-4 Conventional Implant Number Four titanium posts per arch Each tooth with one implant Angle Placed at an angle of 45° No angulation Duration 4-6 months 4-6 months Bone graft Bone graft is rarely needed  Bone graft is needed Procedure Minimally invasive Multiple surgeries Cost Affordable >price because of less number of implants Expensive if you replace each missing tooth with an implant
What Is the Procedure for All-on- 4 Dental Implants?
The All-on-4 implant system is a quick way to restore missing teeth with a new set.
After all necessary extractions and appropriate healing, your dentist surgically inserts four titanium posts into your jaw and places a permanent denture over these posts.
All on 4 Dental Implant Procedure
All-on-4 treatment procedure consists of 2 phases: surgical and rehabilitation.
After taking records and treatment planning, the whole procedure takes about 2 hours per arch, or approximately 4 hours for the whole mouth.
Each patient is different, so additional time may be needed for the procedure.
Survival Time of All-on-4 Implants
The survival rate of dental implants depends on proper care and good oral hygiene methods.
However, before undergoing the procedure, the following factors should be viewed accurately:
- The quality of bone
- Number of implants
- Length of implant
- Patient’s systemic conditions
How Much do All on 4 Dental Costs?
All-on-4 price ranges between $17,000 – $30,000 per arch. Depending on your requirements, additional charges can be applied.
All-on-4 dental implant costs depend on your health condition, the number of missing teeth, bone density, and material choice for the implant.
Charges may vary depending on:
- Dental x-ray, CT, and CBCT charges
- Type and material chosen
- Specialist’s experience
- The number of dentists involved
Find below the price range of all-on-4 implants and insurance and dental plans at different locations.
On your first visit, ask your dentist the cost of an all-on-4 implant to help you decide your treatment plan and discuss the insurance coverage for implants.
All-on-4 is not a treatment procedure, but it is an investment for your oral health, function, and esthetics. So invest it wisely!
Materials Used in All-on-4 Implants
Hybrid fixed dentures are made of either acrylic, zirconia, or porcelain. These dentures or bridges provide excellent esthetics.
Titanium is the perfect choice for implant posts because it closely matches the human body and is biocompatible.
It fuses with your jaw bone via a process called osseointegration and functions as part of it.
The choice of material for implants depends on esthetics, durability, patient age, cost, and opposing teeth.

Material Advantage Disadvantage Cost Acrylic Least expensive Customized shape and size Easy to repair Less esthetic Less durable Wear down easily Breaks easily $20,000-$30,000 Composite Affordable Less esthetics $20,000-$30,000 Porcelain Excellent esthetics Durable Repairable Expensive From $50,000 Zirconia Very strong and durable Expensive Hard to repair Clicking sound on chewing From $34,000
What Are the Complications of All-on-4 Dental Implants?
The success rate of dental implant treatment is high; however, 5 to 10% of cases fail shortly after the procedure or after several years.
Following are the potential complications that can occur after the treatment:
Peri-implantitis is an inflammatory process affecting the tissue around a dental implant that leads to loss of supporting bone.
You may experience excessive bleeding from the gums, infection, awful breath, and unpleasant taste.
When peri-implantitis occurs, your dentist temporarily removes your denture. He then cleans the gums and implants with disinfectants.
Then, he remounts the bridge and dentures over the implant. He checks the bite to see if any discomfort remains after placing the implant.
Peri-implantitis | All-on-4 Dental Implants Complication
- Speech problems
- Nerve damage
- Persistent pain
Consistent dental care and regular follow-up help prevent these complications.
Fracture of the Implant
Implant body fracture is rare, but it may occur because of excess pressure before osseointegration, design, or material failure.
You may experience bleeding from the gums and loose or ill-fitting crown.
When an implant fracture occurs, your dentist will remove and replace it with a new implant.
Fracture of the Denture
It is a prevalent problem in the lower arch.
Your dentist can repair the broken dentures with the help of acrylic resins and fix the loose screws by retightening them.
Implant cost varies depending on the number, condition of your gum and bone quality.
Extra dental procedures such as extraction, x-ray scans, and bone graft surgery will also add to your cost.
Dental insurance can cover part of the procedure cost so ask your dentist about the insurance coverage before treatment.
People may opt for cheap implants rather than spend money on expensive procedures.
Risks associated with cheap implants are:
- Aesthetically unattractive
- Poor quality material
- Higher chances of implant failure and complications
How Are All-on-4 Implants Different From Dentures?
Implants are a substitute for tooth roots and act as artificial roots. In comparison, dentures are removable prostheses and a replacement for missing teeth.
Implants do not compress your gums like traditional dentures and are fixed and comfortable, whereas conventional dentures are removable and less comfortable while talking and chewing.
All-on-4 prevents bone resorption and saves bone structure, but dentures speed up bone resorption because of pressure on the gum and bone.
