All-on-4 Dental Implants Turkey

The “All-on-Four” treatment is an advanced dental implant procedure designed to provide a full-arch prosthesis using only four implant fixtures

All-on-Four Treatment

Overview: The All-on-Four treatment concept is a revolutionary approach to rehabilitate patients who have lost all their teeth in one or both jaws, or whose teeth are so compromised that they need a full arch replacement. This method relies on the strategic placement of just four dental implants to support an entire arch of teeth.

Key Features:

1. Fewer Implants: Traditional full-arch implant methods often require six to eight implants. The All-on-Four method reduces this to just four implants.
2. Angled Rear Implants: Two of the four implants are placed at an angle in the back of the jaw. This takes advantage of denser bone areas, often eliminating the need for bone grafts, which are sometimes required in traditional implant procedures.
3. Immediate Loading: A primary advantage of the All-on-Four method is the possibility of immediate loading, meaning a temporary set of teeth can often be placed on the same day as the implant surgery. This provides the patient with an immediate full-arch restoration.
4. Cost-Effective: Due to the reduced number of implants and potential elimination of bone grafting, the All-on-Four procedure can be more cost-effective compared to other full-arch restoration methods.

Procedure:

1. Initial Consultation: A comprehensive examination, including X-rays and 3D scans, determines the patient’s eligibility and customizes the procedure.
2. Implant Placement: Four dental implants are strategically placed in the jaw – two at the front and two at the back angled up to 45 degrees.
3. Attachment of Prosthesis: Once the implants are in place, they can be immediately loaded with a provisional set of teeth, made of high-quality resin.
4. Healing: Over the following months, the implants integrate with the bone in a process called osseointegration.
5. Final Prosthesis: Once healing and osseointegration are complete, the temporary teeth are replaced with the final, more durable prosthesis, usually made of materials like porcelain or a more robust acrylic.

Benefits:

1. Speedy Rehabilitation: Patients can leave the dental office with a full set of teeth on the same day.
2. Improved Oral Function: Restores almost full chewing function, allowing patients to enjoy a varied diet.
3. Aesthetics: Provides a natural-looking restoration, enhancing facial aesthetics and smile.
4. Bone Preservation: Prevents potential bone loss that often occurs with missing teeth.
5. Fixed Solution: Unlike removable dentures, the All-on-Four prosthesis is fixed in place, offering more stability and comfort.

All-on-Four Treatment Concept:

Foundational Principles:

1. Biomimetic Approach: All-on-Four imitates the natural orientation and function of teeth. The angled placement of the posterior implants aims to simulate the natural angulation of tooth roots, thereby maximizing the use of available bone.
2. Strategic Distribution: The four implants are distributed in such a manner that they evenly distribute the biting forces across the jaw, providing stability and reducing wear and tear.

Detailed Procedure:

1. Initial Diagnosis: The dentist uses digital imaging, such as cone-beam computed tomography (CBCT), to visualize the patient’s jaw in three dimensions. This aids in understanding the bone quality, quantity, and anatomical structures, ensuring the precise placement of implants.
2. Treatment Planning: Using advanced software, a surgical guide may be developed to facilitate the exact positioning of implants during surgery.
3. Extractions: If any teeth remain, they are extracted. In many cases, the All-on-Four procedure can be done immediately after extractions.
4. Implant Placement: Two anterior implants are typically placed vertically, while the two posterior implants are angled at about 30° to 45°. This angled placement is crucial as it allows engagement of more bone tissue, especially in patients who have bone loss in the posterior region and would otherwise require bone grafting.
5. Provisional Prosthesis: On the day of surgery, after implant placement, an immediate provisional (temporary) dental bridge is fixed onto the implants. This is one of the major advantages of the procedure, offering immediate aesthetics and function.
6. Healing Phase: Over the next few months (usually 3-6 months), the bone fuses to the implants in a process called osseointegration. The patient usually follows a soft diet during this period to avoid undue stress on the newly placed implants.
7. Final Restoration: After complete healing, the provisional prosthesis is replaced with a final, durable prosthesis. This is typically made from high-grade materials like porcelain, zirconia, or reinforced acrylic.

Considerations for the All-on-Four Treatment:

1. Bone Quality and Quantity: While the procedure is designed to maximize available bone, extreme cases of bone loss might still necessitate bone grafting.
2. Oral Hygiene: Proper care is crucial. Specialized brushes and other oral hygiene tools are often recommended to maintain the health of the gums around the implants.
3. Regular Check-ups: Periodic visits to the dentist are vital to monitor the implants, the health of the soft tissues, and the condition of the prosthesis.
4. Lifestyle Factors: Smoking, uncontrolled diabetes, and certain other conditions can affect the success rate of implants. It’s essential to discuss such factors with the dentist.
5. Durability: While the prosthetics are designed to be durable, they might require replacement or maintenance after several years, depending on wear and tear.

In conclusion, the All-on-Four treatment concept is a sophisticated blend of surgical precision, prosthetic artistry, and biomechanical principles, providing edentulous patients (or those with severely compromised teeth) an opportunity to regain a full set of teeth with minimal implants and in a relatively short period. It’s a testament to how far dental implantology has advanced, merging aesthetics, function, and longevity.
