Complete toothlessness, or reaching the stage of losing all existing teeth in the mouth due to periodontal diseases, is a serious medical condition that directly threatens the digestive system, speech function, and jawbone volume. The removable dentures offered as a solution to this condition in traditional dentistry accelerate bone resorption over time and create a lack of comfort, because they cannot transmit chewing force to the jawbone.
Today, modern implantology has developed the All on four (all on 4) concept to eliminate these biomechanical disadvantages created by removable dentures. Applied at Dentram clinics with the “Fixed Teeth in One Day” protocol, this technique is a scientific standard that provides patients with functional fixed teeth on the same day, without the need for advanced surgery.
What Is the All on 4 Concept and How Does It Work?
In traditional implant treatments, generally 6 to 8 implants are needed to rehabilitate a fully edentulous jaw with fixed prostheses. However, in patients who have been toothless for a long time, sufficient bone volume is not present, especially in the posterior regions of the jaws (due to the sinus cavities in the upper jaw and the mandibular nerve canal in the lower jaw).
The All on four (all on 4) technique overcomes precisely these anatomical limitations with a cleverly designed engineering approach. In this technique, only 4 implants are placed in each jaw:
- 2 implants are placed in the anterior region (the area where the bone is thickest and densest) at a straight angle (90 degrees),
- and 2 implants are placed in the posterior region at angles of 30 to 45 degrees, in order to avoid anatomical cavities and to distribute the chewing force over the widest surface.
Biomechanical Advantages and Restoration of Function
Thanks to the angled placement of the posterior implants, the existing potential of the jawbone is used to the maximum. Dentram founder and Oral, Dental and Maxillofacial Surgery Specialist Prof. Dr. Serhat Yalçın expresses the rational surgical advantages this technique provides to patients as follows:
“In classic full-jaw implant treatments, the biggest handicap is the sinus lifting or bone powder procedures we apply to compensate for bone resorption in the posterior regions. These procedures can extend the treatment period from 6 months to 1 year. The All on four (all on 4) concept, on the other hand, is a complete biomechanical engineering marvel. By placing the posterior implants at an angle, we bypass the problematic anatomical regions and spare our patient from bone-formation operations that would take months. Onto these 4 implants, which anchor to the bone with high torque, we screw the fixed temporary teeth on the same day as the surgical procedure, enabling our patient to leave the clinic having regained their chewing function.”
Why Should All on 4 Treatment Be Preferred?
We can list the most fundamental reasons why All on 4 treatment has begun to be widely preferred in Türkiye, as it is all over the world, as follows:
1. No Need for Advanced Surgery (Bone Grafting)
Thanks to the angled implant placement, the existing healthy bone in the jaw is used. Sinus lifting or extra surgical procedures such as massive bone powder addition, and the long healing times they bring, are not needed.
2. The Comfort of Fixed Teeth in One Day (Immediate Loading)
On the day the operation is completed, the fixed temporary prostheses prepared in advance in a laboratory environment are screwed onto the implants. The patient regains their speech and aesthetic functions on the same day, without having to use a removable denture. Approximately 3 months later, once the fusion, that is, the bone integration process, is complete, the permanent porcelain or zirconium teeth are attached.
3. Shorter Treatment Time and High Comfort
The reduction of the number of operations to one and the shortening of the wound-healing process reduce the time the patient spends in the chair while maximizing their psychological and physiological comfort.
4. Proven Clinical Success
Followed in the scientific literature for over twenty years, the All on 4 concept is an extremely reliable treatment protocol with a success rate of over 98% when applied with correct indication and digital planning.
Diagnosis and Digital Planning at Dentram
In our clinic, the All on four (all on 4) process begins from 3D Dental Volumetric Tomography (CBCT) data. A millimetric analysis of the jawbone is performed, and the angles at which the implants will be placed, the bone density, and the nerve pathways are simulated in a digital environment. This rational planning, which leaves no room for surprises, is the fundamental condition for the surgical stage to proceed flawlessly and rapidly.
If you want to be free of the troubles created by removable dentures, or if you are faced with the risk of losing all the teeth in your mouth, you can book a digital analysis and consultation appointment with our specialist physician team to evaluate the suitability of the “Fixed Teeth in One Day” protocol for you.
