Key takeaways
All-on-6 uses six strategically placed dental implants to support a full arch of prosthetic teeth, providing more stability than All-on-4
The three main implant components are the fixture (implant), abutment (connector), and prosthesis (artificial teeth)
Osseointegration is the biological process where titanium implants fuse with the jawbone, typically taking 3-9 months
Materials include titanium (most common) and zirconia (metal-free option), with prosthetic teeth available in acrylic, porcelain, or zirconia
Potential complications include peri-implantitis, implant failure, and nerve damage - understanding these helps you recognize warning signs
What Is All-on-6?
All-on-6 is a full-arch dental restoration procedure that uses six strategically placed dental implants to support a complete prosthetic arch of 10-14 teeth. This approach provides additional support and stability compared to the All-on-4 method, making it particularly beneficial for patients with moderate bone density S1, S3.
The key difference between All-on-6 and All-on-4 lies in the number of implants used. While All-on-4 uses four implants strategically angled to maximize contact with available bone, All-on-6 adds two additional implants to distribute bite forces more evenly across the arch. This additional support can be particularly advantageous for patients who may have slightly less bone density or who require greater prosthetic stability S4.
Edentulism refers to the condition of being toothless - having lost some or all of one's natural teeth. This is the underlying condition that All-on-6 treatment addresses S2.
When All-on-6 May Be Recommended
All-on-6 may be recommended when a patient has sufficient bone volume to support six implants but could benefit from the additional stability that more implant fixtures provide. Your dental provider will determine the most appropriate approach based on your individual bone structure and oral health condition.
For international patients considering dental tourism in Istanbul, understanding these technical differences helps in discussions with dental providers. The procedure can be an effective solution for edentulism, and many patients travel abroad to access quality dental care at competitive prices.

Understanding the Three Implant Components
A complete dental implant restoration consists of three main components, each serving a distinct function in the overall prosthetic system S1, S2.
The Implant Fixture (Implant)
The implant fixture, commonly referred to as the implant itself, is the screw-shaped component that is surgically placed into the jawbone to replace the missing tooth root. Made most commonly from medical-grade titanium, the fixture is designed to be biocompatible, meaning it integrates naturally with human bone tissue. The surface of the implant is often treated or coated to enhance osseointegration - the process by which the bone fuses to the implant surface S1.
The Abutment
The abutment serves as the critical connector piece between the implant fixture and the prosthetic tooth (prosthesis). It is typically attached to the implant after osseointegration is complete, protruding through the gum line to provide a stable foundation for the artificial teeth. The abutment can be made from titanium, zirconia, or other materials, and its design varies depending on whether the final prosthesis will be fixed (permanent) or removable S2.
The Prosthesis
The prosthesis refers to the artificial teeth - the visible portion of the dental restoration that functions like natural teeth. In an All-on-6 procedure, the prosthesis is a full-arch dental bridge typically containing 10-14 teeth fused to a metal or acrylic framework. This prosthetic arch is secured to the abutments, providing patients with a functional and aesthetic replacement for their natural teeth S1.
The All-on-6 Procedure: Key Terms
CBCT Scanning
Cone Beam Computed Tomography (CBCT) is a specialized 3D imaging technique used extensively in dental implant planning. Unlike traditional dental X-rays, CBCT provides a detailed three-dimensional view of the jawbone, sinuses, nerves, and surrounding anatomical structures. This detailed imaging allows the dental surgeon to precisely plan implant placement, assess bone quality and quantity, and identify any potential complications before surgery S1, S3.
Surgical Guide
A surgical guide is a custom-made device fabricated from the patient's CBCT scan and digital impressions. This guide fits over the teeth or implants during surgery, directing the precise angle and depth of implant placement. Surgical guides help ensure accuracy, reduce surgical time, and minimize trauma to surrounding tissues. They are particularly valuable in All-on-6 procedures where precise implant positioning is critical for optimal prosthetic outcomes S3.
Immediate Load vs. Delayed Load
The terms immediate load and delayed load refer to different treatment protocols for when the prosthetic teeth are attached to the implants:
Immediate load: The temporary prosthesis is attached to the implants within 24-48 hours of surgery, allowing patients to have functional teeth immediately. This approach requires excellent primary implant stability and may not be suitable for all patients.
Delayed load: The traditional approach where the implants are allowed to heal for several months before the final prosthesis is attached. This allows complete osseointegration before placing functional forces on the implants S1.
Treatment Timeline
The All-on-6 procedure typically spans several months. Initial consultation and imaging (CBCT) are followed by implant surgery. A healing period of 3-9 months allows for osseointegration, after which the final prosthesis is fabricated and attached. Your dentist will determine which loading protocol is appropriate for your specific situation.
Osseointegration: The Healing Process
Osseointegration is the fundamental biological process that makes dental implants possible. During this healing phase, the titanium implant fixture fuses directly with the surrounding jawbone, creating a stable foundation for the prosthetic teeth S1, S2.
The timeline for osseointegration typically ranges from 3 to 9 months, with considerable variation depending on individual factors such as bone quality, overall health, and adherence to post-operative care instructions S1. During this period, patients must follow specific guidelines to protect the healing implants:
Avoid putting pressure on the implant site
Maintain excellent oral hygiene as directed
Follow dietary recommendations during the healing phase
Attend all scheduled follow-up appointments
Avoid smoking, which can impair healing
Factors that may affect osseointegration include bone density and volume at the implant site, the patient's overall health status, certain medical conditions, medications, and lifestyle factors such as smoking. Patients with conditions affecting bone healing or those taking certain medications should discuss these factors with their dental provider S1.
Materials and Types
Titanium vs. Zirconia Implants
The choice between titanium and zirconia implants represents one of the significant decisions in implant dentistry. Both materials have distinct characteristics that may make them more suitable for different patients S1, S3.
Titanium implants are the most widely used option in dental implantology. Titanium is highly biocompatible, corrosion-resistant, and has a proven track record spanning decades. The metal's ability to osseointegrate with bone is well-documented, and titanium implants have a long history of successful clinical outcomes. Some patients, however, have concerns about metal sensitivity or prefer metal-free options S1.
Zirconia implants offer a metal-free alternative for patients with metal allergies or sensitivities. Zirconia is a ceramic material that is white in color, potentially providing better aesthetic results in areas where gum tissue is thin. However, zirconia implants may have different handling characteristics and may not be suitable for all clinical situations S3.
Material Selection
The choice between titanium and zirconia implants should be made in consultation with your dental provider, who can assess your specific needs, allergies, and clinical situation to recommend the most appropriate material for your case.
Types of Dental Implants
Dental implants are categorized primarily by their design and how they interface with the jawbone:
Endosteal implants are the most common type, placed directly into the jawbone. These screw-shaped implants act as artificial tooth roots and provide a stable foundation for replacement teeth. Endosteal implants are typically used when there is sufficient bone height and width to support the implant S1.
Subperiosteal implants are placed under the gum but above the jawbone. This type is used when there is insufficient bone height for endosteal implants or when the patient cannot or does not want to undergo bone grafting procedures. The implant rests on top of the bone but beneath the gum tissue S1.
All-on-6 procedures typically use endosteal implants, as this approach requires the implants to be anchored directly into the jawbone for maximum stability.
Prosthetic Materials
The prosthetic teeth (the visible artificial teeth) can be fabricated from several different materials, each with distinct characteristics S2, S3:
Acrylic (Composite): Often used for temporary prostheses, acrylic is a cost-effective option that is easy to adjust and repair. It may wear more quickly than other materials.
Porcelain (Ceramic): Provides excellent aesthetics and durability. Porcelain closely mimics the appearance of natural teeth and is highly resistant to staining.
Zirconia: The strongest and most durable option, zirconia prosthetic teeth are highly resistant to chipping and wear. They also offer excellent aesthetic properties.
Your dental provider can discuss the advantages and considerations of each material based on your specific needs, budget, and aesthetic goals.
Understanding Potential Complications
Peri-Implantitis
Peri-implantitis is an inflammatory condition affecting the gum and bone surrounding a dental implant. Similar to periodontitis (gum disease), it involves inflammation of the soft tissues and progressive loss of the bone that supports the implant. This condition can lead to implant failure if not treated promptly S1, S2.
Risk factors for peri-implantitis include poor oral hygiene, smoking, uncontrolled diabetes, and a history of gum disease. Early signs may include bleeding on probing, gum redness or swelling, and progressive bone loss visible on X-rays.
Implant Failure
Implant failure refers to the loss of an implant due to various complications. This can occur early (during the healing phase) or later (after osseointegration has occurred). Early failure is often related to infection, inadequate bone quality, or poor primary stability. Late failure may result from overload, poor maintenance, or peri-implantitis S1.
While dental implants have high success rates, individual outcomes can vary based on bone quality, oral hygiene maintenance, smoking status, and underlying health conditions S1.
Nerve Damage
Nerve damage (paresthesia) is a potential risk, particularly with implants placed in the lower jaw where the inferior alveolar nerve runs. This nerve provides sensation to the lower lip and chin. Proper pre-operative planning using CBCT scanning helps dental surgeons avoid damaging these nerves. In rare cases, temporary or permanent numbness may occur S1.
Warning Signs to Watch For
Contact your dental provider promptly if you experience:
Severe pain or swelling that doesn't subside
Unusual bleeding or discharge
Numbness or tingling in the lips, chin, or tongue
Loosening of the prosthesis or implant
Signs of infection such as fever or pus
Specialists and Surgical Terms
Oral Surgeon vs. Prosthodontist vs. Periodontist
Understanding the roles of different dental specialists can help you navigate your All-on-6 treatment:
Oral and Maxillofacial Surgeon: A dental specialist who performs surgical procedures in the mouth, jaw, and face. Oral surgeons place the dental implants and handle extractions, bone grafting, and other surgical aspects of treatment S2.
Prosthodontist: A dental specialist focused on designing and fitting prosthetic devices like crowns, bridges, and dentures. In All-on-6 treatment, the prosthodontist designs the prosthetic teeth and ensures proper function and aesthetics S2.
Periodontist: A dental specialist focused on the supporting structures of teeth, including gums and bone. Periodontists may be involved in treating gum disease and assessing bone health for implants S2.
Our dentists page provides information about the dental professionals who may be involved in your All-on-6 procedure.
Bone Grafting
Bone grafting is a surgical procedure that adds bone or bone-like material to the jaw to increase bone volume and density. This procedure may be necessary when a patient has insufficient bone to support dental implants S3. The graft material can come from the patient (autograft), a donor (allograft), or synthetic sources (alloplast).
Sinus Lift
A sinus lift (also called sinus augmentation) is a surgical procedure that adds bone to the upper jaw in the area of the molars and premolars, between the jaw and the maxillary sinuses. This procedure is necessary when the sinus floor is too close to the implant site due to bone loss S2.
Fixed vs. Removable Prosthesis
Fixed prosthesis: The prosthetic arch is permanently attached to the implants and can only be removed by a dental professional. This provides the most natural feel and function.
Removable prosthesis: The prosthetic arch can be taken out by the patient for cleaning. This may be preferred by some patients for maintenance convenience S3.
Planning and Assessment Terms
How to Know If You Have Enough Bone for All-on-6
Determining whether you have sufficient bone for All-on-6 requires professional assessment, typically involving CBCT scanning and clinical examination. The assessment evaluates:
Bone height (vertical dimension available for implant placement)
Bone width (horizontal dimension of the jawbone)
Bone density (quality of the bone tissue)
Anatomical structures to avoid (nerves, sinuses)
While All-on-6 uses six implants to provide additional support and may be suitable for patients with moderate bone density, sufficient bone volume is still generally required S1. Patients with significant bone loss may require bone grafting or consider alternative treatment options.
Assessment Process
During your initial consultation, your dental provider will evaluate your bone structure using CBCT imaging and discuss whether All-on-6 is appropriate for your specific situation. Factors considered include your medical history, oral health, bone quality, and treatment goals.
