While searching for dental implants to replace missing teeth, you may find information about both the “all-on-4” and “all-on-6” procedures.

In the past, dentists typically required 8 to 10 dental implants per arch for a complete mouth reconstruction to ensure sufficient support for replacing missing teeth.

During the “all-on” method, the dental implants are placed at an angle in the jawbone to allow for greater coverage and securement of replacement teeth.

Both of these dental treatments will still give you a gorgeous smile. The number of implants placed is the sole variation.

Consult a reputed dentist to ensure you get  best all-on-4 dental implants.

Which implant process is right for you? Let’s find out!

Difference between all-on-4 and all-on-6 dental implants

Understanding the difference will help you decide which option is most suitable for you.

What do dental implants consist of?

Dental implants are recommended by dentists as replacements for missing teeth.

  • Initially, your dentist will surgically insert the dental implant into your jawbone.
  • The implant will integrate within your jaw within the next few months, a process known as osseointegration.
  • A portion of the dental implant protrudes above the gum line. It serves as a support for covering either full or partial teeth.

Whether you require dental implants or orthodontic dental treatment, discuss all your queries before starting the treatment.

The fixed dental implant prosthesis offers the advantages of dentures without worrying about teeth falling out. This makes your daily life simpler.

  • You can smile, eat, and speak as you did with your real teeth.
  • You can still brush and floss as usual. This helps you maintain good oral hygiene.

Your dentist might not recommend dental implants if you’ve got poor jaw-bone stability. 

Without a strong jawbone, your dental implants cannot support fixed tooth replacements.

What are all-on-4 and all-on-6 dental implants?

The all-on-4 dental implant uses four implants. These implants replace either the upper or lower set of teeth and function as a support system for your new set of permanent teeth.

The all-on-6 dental implant also replaces your teeth in the upper or lower jaw. It encompasses a bridge that is supported by six dental implants.

All-on-4 dental implant procedure

  • Four implants are placed in each arch without any grafting.
  • Two of them are positioned vertically in front of your mouth.
  • Two angled implants are located in the back of your mouth.
  • The best all-on-4 implants consist of a hybrid denture that is fixed onto rods.
  • The rod is then attached to either upper or lower teeth.
  • If your teeth are not in good shape, the all-on-4 dental implant is an excellent option for you. Instead of getting separate replacements for all your teeth, you can opt for just 4 implants.

All-on-6 dental implant procedure

  • You may need bone grafting in an all-on-6 dental implant procedure.
  • The six implants support a bridge. The bridge is positioned in either the upper or lower jaw bone.
  • The bridge provides permanent support for your artificial teeth.
  • The six dental implants offer a lasting solution for problems. These include issues with smiling, chewing, and eating.

Similarities between the best all-on-4 implants and all-on-6 implants

  • Both dental treatments are equally effective. The all-on-4 and all-on-6 dental implants replace missing teeth in your upper or lower jaw.
  • They are both offer permanent support. They provide a foundation for your artificial teeth, keeping them fixed and secure in place. You do not need to worry about dentures moving in your mouth.
  • Both processes are alike. These implants are inserted to provide support for the permanent dentures. A temporary denture is placed during the initial phases of jaw bone integration before permanent dentures are placed.

All-on-4 and all-on-6 differences

Number of implants

All-on-4 involves only four implants. While in All-on-6, your dentist will use six implants.

In all-on-4, the four implants are placed in either the upper or lower jaw.

The six implants function similarly to the four implants. But it involves two extra implants to provide extra support. This improves the stability of the dental bridge.

Requirements for bone grafting

In all-on-6, there is a higher probability of requiring bone grafting. However, your dentist can perform All-on-4 implantation even with low bone density.

All-on-6 offers greater stability

All-on-6 implants offer greater stability and strength. Stability depends on your mouth, gums, and jawbone health.

The addition of two more implants in the all-on-6 dental implant strengthens the jaw.

The price of all on-6 is higher

The all-on-6 costs more compared to the best all-on-4 implants. This is mainly due to the inclusion of two extra implants and the potential need for bone grafting.

It is more challenging to clean all-on-6

Due to more implants and complex procedures, maintaining oral hygiene might be a bit difficult with all-on-6. This drawback is significantly reduced when you opt for all-on-4 implants. You can maintain oral hygiene easily.

Various angles of dental implants

The all-on-4 technique involves positioning dental implants at various angles. The all-on-6 method involves placing implants in a straight manner.

How to determine which type of implant restoration works best for you?

Your dentist will assist you in deciding which option is most suitable. Your dentist may suggest or perform various examinations to decide which type is appropriate for you.

  • Your overall dental health
  • The dimensions of your mouth
  • The kind of bite you have
  • The strength of your jawbone
  • The alignment of your original teeth.
  • Your budget

Cost is also an important factor when you’re considering orthodontic dental treatment.

Consult your dentist and make the right choice

Both the all-on-4 and all-on-6 dental implants provide permanent remedies for tooth loss. There is no incorrect choice when deciding.

The decision that best fits your needs should be made by you and your dentist together.

Regardless of the circumstances, both methods are excellent for replacing missing teeth.

Make sure to see a dentist with plenty of experience, no matter what choice you make for your procedure.
