All-on-Four implant treatment is an innovative treatment method developed today for patients who have lost their teeth for any reason. In this method, four implant screws are placed into the jawbone. Afterwards, support is provided for a fixed prosthesis, and the patient can receive new teeth on the same day. Unlike conventional implant treatment, All-on-Four treatment can be performed without the need for bone grafting. It offers patients a faster healing process. Specialist Dentist Dr. Emin Serhat Arıkan, who provides services to patients in Adana, explains what the All-on-Four technique is, how it is applied, its advantages, and which patients it may be suitable for.
What Is All-on-Four Implant Treatment?
All-on-Four implant treatment, also known as the four-implant technique, is a method preferred in cases where the patient has lost all teeth or has experienced severe tooth loss. It is performed with a prosthesis fixed onto only four implant screws. It supports a full dental bridge that replaces missing teeth in the upper or lower jaw.
In four-implant treatment, two implants are placed vertically in the front part of the jawbone. The other two implants are placed at an angle in the posterior region. One of the most important advantages of this treatment procedure is that it may allow implant placement even in cases where bone density is not sufficient.
Who Is All-on-Four Implant Treatment Suitable For?
All-on-Four implant treatment was developed for patients who have lost all of their teeth or have experienced significant tooth loss. In addition, it may be an attractive solution for patients who have difficulty using conventional removable dentures. In some cases, removable dentures can cause irritation and significant discomfort.
This method allows the teeth to be fixed in place. It may also be considered for patients who do not have sufficient bone quality for conventional implant treatment. In patients with inadequate jawbone density, traditional implant treatment may require bone grafting. However, four-implant treatment may be applied even with a minimal amount of bone volume.
How Is All-on-4 Treatment Performed?
All-on-4 treatment is one of the implant methods used in the rehabilitation of complete edentulism or advanced tooth loss. The treatment process is planned individually by considering the patient’s oral and dental health, jawbone structure, and general health status. The procedure is carried out according to stages determined by clinical evaluation and imaging findings.
Examination and Treatment Planning: In the first stage of treatment, a detailed intraoral examination is performed by the dentist. The volume, density, and anatomical structure of the jawbone are evaluated using imaging methods such as panoramic radiography or three-dimensional dental tomography. Based on these evaluations, the implant placement plan is prepared and the appropriate treatment process is determined for the patient.
Placement of the Implants: During the surgical procedure, a total of four dental implants are placed in the upper or lower jaw. In general, the two implants in the anterior region are positioned vertically, while the two implants in the posterior region are placed at specific angles according to the anatomy of the jawbone. This planning aims to make optimal use of the existing bone structure. The procedure is usually performed under local anesthesia. When necessary, different anesthesia methods such as sedation may also be preferred.
Temporary Prosthesis Application: In suitable patients, a temporary fixed prosthesis may be used on the same day after implant placement. However, this application may not be suitable for every patient. The timing of the temporary prosthesis is determined by the dentist according to the primary stability of the implants and the patient’s clinical condition.
Healing and Osseointegration Process: A certain healing period is required for the implants to biologically integrate with the jawbone. Although this period varies depending on the patient’s general health and healing capacity, it usually takes several months. During this period, it is important for the patient to maintain good oral hygiene, follow dietary recommendations, and attend follow-up appointments regularly.
Placement of the Final Prostheses: After it is determined that the implants have adequately integrated with the jawbone, the final prostheses specially prepared for the patient are placed. The design of the prostheses is planned by considering the patient’s oral structure, jaw relationships, aesthetic expectations, and functional requirements. Regular dental check-ups and oral care after treatment are important factors supporting the long-term success of the implants.
What Are the Characteristics of the All-on-4 Method?
All-on-4 is an implant treatment method in which a fixed full-arch prosthesis is planned on four dental implants for the rehabilitation of complete tooth loss. The main features of the method are as follows:
It Is Planned on Four Dental Implants
In this method, four dental implants placed in the upper or lower jaw provide support for a fixed full-arch prosthesis.
Implants May Be Placed at Different Angles
Generally, the implants in the anterior region are placed vertically, while those in the posterior region may be positioned at specific angles according to the structure of the jawbone. The placement plan is prepared according to the patient’s anatomical characteristics.
It Is a Fixed Prosthetic System
The prostheses used in the All-on-4 method are fixed onto the implants. The design and application of the prosthesis are determined according to the treatment plan.
It Is Planned Individually
Before treatment, the jawbone, oral structure, and overall oral health are evaluated through clinical examination and radiological imaging. The regions where the implants will be placed and the prosthetic plan are determined based on these evaluations.
It Can Be Applied to the Upper and Lower Jaw
According to the dentist’s evaluation, the treatment may be applied only to the upper jaw, only to the lower jaw, or to both jaws.
What Are the Advantages of All-on-4 Treatment?
When appropriate patient selection is made, All-on-4 treatment may provide several advantages. The benefits may vary depending on the patient’s oral structure and treatment plan.
A Temporary Prosthesis May Be Applied on the Same Day in Suitable Cases
In some patients, a temporary fixed prosthesis may be used on the same day after implant placement. Whether this is possible depends on the treatment plan.
It May Reduce the Need for Additional Surgical Procedures in Some Patients
By placing the implants at specific angles, the need for additional surgical procedures such as bone grafting or sinus lifting may be reduced in suitable cases. However, this does not apply to every patient.
It May Provide a Fixed Prosthesis Option
In suitable patients who have difficulty using removable dentures, a fixed prosthesis may contribute to greater comfort in daily life.
It May Support Chewing and Speech Functions
After the adaptation period, fixed prostheses may help improve chewing and speech functions. The adaptation process may vary from person to person.
It May Contribute to Meeting Aesthetic Expectations
The prostheses are custom-designed according to the patient’s oral structure, jaw relationships, and aesthetic expectations. This may help achieve a natural-looking aesthetic result.
It May Support the Maintenance of Oral Hygiene
When the care methods recommended by the dentist are followed, the cleaning of the implants and prostheses can be maintained regularly. Oral hygiene and routine check-ups are important for long-term success.
What Are the Differences Between All-on-4 and Conventional Implant Treatment?
All-on-4 and conventional implant treatment may differ in terms of the number of implants, treatment planning, surgical procedures, and prosthetic process. Which method is preferred is determined by the dentist according to the patient’s oral and dental health, jawbone condition, number of missing teeth, and treatment needs. Both treatment methods can be applied in different clinical situations. Therefore, rather than talking about a definitive superiority, it is important to evaluate which approach is more suitable for the patient.
Number of Implants: In the All-on-4 technique, a fixed full-arch prosthesis is generally planned on four dental implants for the treatment of complete edentulism. In conventional implant treatment, the number of implants varies depending on the number of missing teeth, the type of prosthesis, and the treatment plan.
Implant Placement: In the All-on-4 method, the implants in the anterior region are generally placed vertically, while those in the posterior region may be positioned at specific angles to utilize the jawbone structure. In conventional implant treatment, the position and angle of the implants are planned according to the patient’s bone structure and the location of the missing teeth.
Bone Grafting and Additional Surgical Procedures: In some patients with insufficient jawbone volume or density, additional surgical procedures such as bone grafting or sinus lifting may be planned in conventional implant treatment. In the All-on-4 technique, the need for these procedures may be reduced in suitable cases due to the implant placement design. However, this is not valid for every patient.
Temporary Prosthesis Application: In suitable patients, a temporary fixed prosthesis may be planned on the same day after implant placement in All-on-4 treatment. In conventional implant treatment, the timing of temporary or final prostheses may vary depending on the condition of the implants, the healing process, and the treatment plan.
Treatment Duration: The duration of treatment may vary in both methods according to the patient’s clinical condition. In suitable cases, the All-on-4 treatment plan may be completed in a shorter time because fewer implants are used and some additional surgical procedures may not be necessary. In conventional implant treatment, the number of implants, additional procedures, and the healing process may affect the treatment duration.
Treatment Cost: The cost of both All-on-4 and conventional implant treatment varies depending on the number of implants, the type of prosthesis, the materials used, and any additional treatments required. Therefore, treatment costs can only be evaluated individually after a clinical examination and treatment planning.
What Should Be Considered After All-on-4 Treatment?
After All-on-4 treatment, it is important to follow the dentist’s recommendations to support healthy healing of the implants and the long-term use of the prostheses. The post-treatment care process includes oral hygiene, dietary habits, and regular check-ups.
- Pay Attention to Oral Hygiene
Regular oral and dental care should be performed to help reduce plaque accumulation around the implants and prostheses. Supportive cleaning products such as soft-bristled toothbrushes, bridge floss, interdental brushes, or oral irrigators recommended by the dentist may be used. The products to be used may vary according to the patient’s oral structure.
- Follow Dietary Recommendations
The dietary plan after treatment is arranged according to the healing process. Soft foods may be recommended during the first days. Until healing is complete, hard, shelled, or excessively forceful foods should be avoided.
- Do Not Miss Regular Dental Check-ups
The condition of the implants and prostheses should be evaluated periodically by the dentist. During follow-up examinations, the tissues around the implants, the fit of the prostheses, and oral hygiene are assessed, and necessary maintenance or adjustments are made.
- Avoid Smoking and Tobacco Products
Smoking and other tobacco products may negatively affect the healing of oral tissues and may be among the risk factors that reduce the success of implant treatment. Therefore, quitting or reducing smoking after treatment is recommended according to the dentist’s advice.
- Consult Your Dentist if You Notice Unusual Symptoms
Mild pain, sensitivity, or swelling may occur after treatment. However, if severe pain, prolonged bleeding, mobility of the prosthesis, or signs suggesting infection are observed, the dentist should be contacted without delay.
How Are All-on-Four Implant Treatment Costs Determined?
The cost of All-on-Four implant treatment may vary depending on many factors, including the patient’s oral and jaw structure, the condition of the bone tissue, the implant and prosthetic materials to be used, whether additional surgical procedures are needed, the technical infrastructure of the clinic, and the experience of the dentist performing the treatment. Therefore, treatment costs are determined individually after a clinical examination and the necessary radiological evaluations.
