All-on-4 and All-on-6 Implant Systems: 2025 Comprehensive Guide

Tooth loss is a serious health problem affecting millions of people worldwide today. Complete tooth loss or multiple tooth loss not only causes aesthetic concerns but also leads to significant declines in chewing function, speech disorders, and overall quality of life. Additionally, untreated tooth loss over time can cause the jawbone to gradually deteriorate (resorption). This situation may necessitate additional procedures such as bone grafting in advanced treatment stages.

While traditional denture applications have been used for years as a solution to this problem, they have numerous limitations. Issues such as constant shifting, dietary restrictions, oral ulcers, and social withdrawal are driving patients to seek more modern solutions.

The fixed implant systems offered by modern dentistry, particularly All-on-4 and All-on-6 technologies, represent revolutionary advancements in this field. These systems enable the achievement of maximum functional and aesthetic results with minimal invasive surgery.

What are All-on-4 and All-on-6?

We can examine these technologies separately, highlighting the differences between them:

All-on-4 System

All-on-4 is an innovative treatment concept developed by Nobel Biocare, in which a fixed prosthesis is supported by four dental implants placed in the upper or lower jaw. In this system, two implants are placed at a right angle in the front region, and two implants are placed at a 30-45 degree angle in the back region.

All-on-6 System

The All-on-6 system is a similar application using six implants. The additional two implants enhance the stability of the prosthesis and are particularly preferred in patients with low bone quality.

Suitable Patient Profile

These systems are ideal for patients in the following situations:

• Patients with complete edentulism
• Patients with multiple tooth loss and unsuitable for bridge treatment
• Patients dissatisfied with their current dentures
• Cases not requiring bone grafting

All-on-4 and All-on-6 Key Differences and Similarities

Both systems offer same-day prosthesis application, but the All-on-6 system provides greater stability and chewing force distribution.

Treatment Process Step by Step

Initial Examination and Assessment

The treatment process begins with a comprehensive oral examination. Dr. Tansu Uzel evaluates the patient’s current condition, taking into account their general health, bone structure and expectations.

Radiological Imaging

Panoramic X-rays and 3D computed tomography (CBCT) scans are used to determine bone structure, nerve locations, and anatomical structures with millimetre precision. These images form the basis for implant placement planning.

Treatment Planning and Implant Placement

Using modern planning software, custom surgical guides are prepared for each patient. Implant surgery is typically completed under local anaesthesia within 1-2 hours.

Temporary Prostheses and Healing Process

A temporary prosthesis is fitted on the same day or within 24-48 hours after surgery. This allows the patient to return to their social life immediately. The healing process takes approximately 3 months.

Permanent Prosthesis Application

Once the implants have fused with the jawbone (osseointegration), the permanent prostheses, custom-designed for the patient, are applied. At this stage, digital measurements, computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies are used to ensure that the prostheses are prepared in the most ideal way, both aesthetically and functionally.

Avantajları Nelerdir?

Daha Az İmplant ile Sabit Protez

Geleneksel yöntemlerde 8-10 implant gerektiren durumlar, All-on-4/6 ile sadece 4-6 implant ile çözülür. Bu durum hem maliyeti düşürür hem de cerrahi travmayı azaltır.

Kısa Cerrahi Süresi

Tek seansta tamamlanan cerrahi işlem, hastane yatış gerektirmez ve hasta aynı gün taburcu edilir.

Hemen Yükleme İmkanı

Geçici protez ile hasta, tedavi sonrası hemen ile beslenmeye başlayabilir.

Ekonomik Avantajlar

Özellikle İngiltere ve İrlanda’dan gelen hastalar için Türkiye’deki tedavi maliyeti, %60-70 oranında daha ekonomiktir.

Kemik Grefti İhtiyacını Azaltması

Açılı implant yerleşimi sayesinde, kemik grefti ihtiyacı minimize edilir veya tamamen ortadan kalkar.

Differences Between All-on-4 and All-on-6

System Selection Based on Bone Structure

• All-on-4: Preferred for patients with sufficient bone volume and density to provide fixed teeth with fewer implants.
• All-on-6: Preferred in cases where bone quality is limited or greater stability is required. Provides a stronger and more balanced support.

Cost Differences

There is no significant cost difference. While All-on-4 uses fewer implants, the cost per implant is higher. All-on-6 uses more implants, but the cost per implant is lower. Therefore, it can be said that there is no cost difference.

Treatment Duration

Both systems can be applied in the same timeframe, but the healing process is more predictable with All-on-6. The treatment process typically takes three months.

Who is Not Suitable?

Systemic Health Issues

• Uncontrolled diabetes mellitus
• Patients undergoing active cancer treatment
• Use of immunosuppressive medications
• Severe bone metabolism disorders

Bone Structure Deficiencies

In cases of severe bone loss, a bone graft may be required first.

Lifestyle Factors

• Patients who refuse to quit smoking
• Patients who do not maintain good oral hygiene
• Patients who cannot attend regular follow-up appointments

Frequently Asked Questions

Does All-on-4 cause pain?

Thanks to modern anaesthesia techniques, no pain is felt during surgery. Minimal discomfort after the procedure can be managed with mild pain relievers.

How long do I need to use a temporary prosthesis?

A temporary prosthesis is typically used for 3 months. This period is necessary for the implants to integrate with the bone.

What should I pay attention to after treatment?

• Apply cold compresses for the first 48 hours
• Soft diet (2-4 days)
• Avoid smoking
• Regular oral hygiene
• Regular attendance at follow-up appointments

Is lifelong use possible?

With proper care and regular check-ups, the All-on-4/6 system can be used successfully for 20-25 years or more. The prosthetic component can be replaced every 10-15 years.
