Dental implant technique
The All-on-4 is a dental implant technique that provides a full set of teeth using only four implants to support a fixed prosthesis. This method is often used for patients who are edentulous (without teeth) or have severely compromised teeth that require extraction. The All-on-4 technique is known for its efficiency and effectiveness in restoring oral function and aesthetics.
Overview[edit]
The All-on-4 technique was developed to maximize the use of available bone in the jaw while minimizing the need for bone grafting. This is achieved by strategically placing four dental implants in the anterior maxilla or mandible, where bone density is typically higher. The posterior implants are often tilted at an angle to increase support and avoid anatomical structures such as the maxillary sinus or the inferior alveolar nerve.
Procedure[edit]
The All-on-4 procedure involves several steps:
Consultation and Planning[edit]
The process begins with a comprehensive evaluation, including dental imaging such as CT scans or panoramic radiographs, to assess bone quality and quantity. A treatment plan is developed based on the patient's specific needs.
Surgical Phase[edit]
During the surgical phase, any remaining teeth are extracted, and the implants are placed. The two anterior implants are placed vertically, while the two posterior implants are angled to provide optimal support. This angulation helps to distribute the forces evenly across the prosthesis.
Prosthetic Phase[edit]
After the implants are placed, a temporary prosthesis is attached, allowing the patient to leave the office with a functional set of teeth. After a healing period, during which the implants integrate with the bone, a final prosthesis is fabricated and attached.
Advantages[edit]
The All-on-4 technique offers several advantages:
- Reduced Treatment Time: The procedure can often be completed in a single day, reducing the overall treatment time compared to traditional methods.
- Cost-Effective: By using only four implants, the cost is generally lower than other full-arch restoration methods.
- Avoidance of Bone Grafting: The strategic placement of implants often eliminates the need for bone grafting, which can be a lengthy and costly process.
- Immediate Function: Patients can receive a temporary prosthesis on the same day as the surgery, allowing for immediate function and aesthetics.
Considerations[edit]
While the All-on-4 technique is highly effective, it may not be suitable for all patients. Factors such as bone density, overall health, and specific anatomical considerations must be evaluated. Patients with severe bone loss may require additional procedures to ensure the success of the implants.
