All-On-Four Dental Implants


New smile in just 48 hours!

The All-On-4 dental implant procedure is a methodology surgical processed to replace an entire arch of missing teeth with only four (4) dental implants supporting a fixed full prosthesis/bridge.

Dental implant-supported teeth look, feel and function like natural teeth. This means that you can eat and drink whatever you choose.

It is beyond doubt that implant-supported bridges improve quality of life. People who have felt embarrassed and worried because of tooth problems are often overwhelmed by the improvements in how they look and feel with their new teeth.

All on four dental implants
  • It's the most rapid solution in terms of total reconstruction of the jaws because it is based in the principle of immediate loading
  • Long-term solution: Warranty on implants for life
  • In the upper jaw with All-on-4 can be avoided both sinus lift and/or bone graft, reducing greatly the treatment time
  • Simply oral hygiene maintenance (toothbrush, toothpaste, mouthwash and floss around the implants)
  • Minimal recovery time after surgery, immediate loading and rapid return to everyday life
  • Computer Assisted Anesthesia - The Wand and possibility of IV conscious sedation

Phases of the All-On-Four Technique


So the dentist can properly assess the requirements and the suitability of the patient for the technique all-on-four is necessary to a consultation in which we take into consideration the various aspects of the treatment and the medical history of the candidate. It may be necessary to run a series of diagnostic investigations including a CT scan to x-rays (Dentascan, Cone-beam), the measurement of bone density and impressions in order to develop diagnostic models in plaster. Many dentists use the dedicated software to plan treatment on the computer that allow for detailed diagnostics such as identification of the bone available, the virtual positioning of the implant according to the patient’s anatomy and prosthetic needs and allow you to fine-tune a mask (surgical guide) on a measure that ensures an accurate and guided implant placement.

After this appointment diagnostic if there is a need for a bone graft or an additional treatment before the implant surgery, will be scheduled for an appointment with surgery, during which it will extract the tooth (if necessary), will be placed the implants and the provisional prosthesis, generally all in the same sitting.


After any tooth extractions, place 4 implants in the jaw in such a way that the bone surrounds them. Implants that are placed in the rear part of the lower jaw are arranged at an angle of about 45 degrees to achieve maximum contact and anchor to the existing bone structure.

Once the four implants have been placed in the jaw, the abutments (components that connect the implant to the teeth, bridge, or denture) will be attached to the implants. The “new teeth” are then set and adjusted to ensure that an occlusion is adequate and the maximum comfort for the patient.


At this point there will be a series of appointments for the next 6 months. At the end of this period, the gums will be fully healed and the implants fully integrated with the natural bone. In this phase, depending on the treatment plan, the dentist will remove the teeth and take new impressions in order to prepare the final set of teeth.

All on Four Comparison

New All-On-Four Technique

1. Requires 4 implants to ensure the arch

2. It is usually an effective solution and the most economic

3. In some cases, may avoid the need for a bone graft

4. The implants and the teeth are positioned and fitted in a single appointment

All on Four Comparison

Traditional Dental Implants

1. Requires 6-8 plants to ensure the arch

2. More expensive as it requires more equipment, more surgeries and more visits to the dentist

3. If you are required bone grafting is a surgical phase in more

4. Requires several appointments and a healing phase of 6 -8 months during which it has to be worn a provisional prosthesis type mobile
