Full arch All-on-4 restorative steps for Immediate loading with conversion denture


In this article, we will discuss the step-by-step process of performing an immediate load prosthesis known as All-on-4 for the mandible. This innovative dental procedure offers patients the convenience of having a fully restored smile in a shorter time frame. We will delve into the details of this procedure, highlighting the key steps involved in achieving successful outcomes.

Day 1: Preparing for the All-on-4 Procedure

Step 1: Evaluation and Treatment Planning

Prior to the procedure, a thorough evaluation of the patient’s dental condition is conducted. This includes taking digital impressions, X-rays, and performing a comprehensive examination. The treatment plan is then developed, considering the patient’s specific needs and expectations.

Step 2: Placement of Dental Implants

The dental implants are strategically placed into the patient’s jawbone during a surgical procedure. The All-on-4 technique involves the placement of four implants, which provides sufficient support for a full arch prosthesis.

Step 3: Prosthesis Pickup

Once the implants are securely placed, a prosthesis pickup is performed. The speaker uses a blue pickup material to capture the position of the implants, ensuring accuracy in the fabrication of the final prosthesis.

Step 4: Temporary Copings

Temporary copings are then attached to the implants to protect them and maintain the proper gingival contour during the healing phase. These temporary copings assist in preserving the shape and position of the soft tissues, ensuring optimal aesthetics and function.

Day 2: Laboratory Phase and Conversion Denture

Step 5: Laboratory Phase

Following the prosthesis pickup, the process moves to the laboratory phase. Here, dental technicians work closely with the dentist to fabricate the permanent prosthesis. The digital impressions obtained earlier serve as a blueprint for creating a custom-fit restoration that perfectly aligns with the patient’s oral structures.

Step 6: Conversion Denture

In the final step of the procedure, a conversion denture is created using Pro base material. This temporary restoration is designed to replicate the appearance and function of the permanent prosthesis. It is securely attached to the implants, allowing the patient to enjoy restored dental aesthetics and immediate chewing ability.


The full arch All-on-4 procedure offers a revolutionary solution for patients seeking immediate restoration of their smile. By following the step-by-step process outlined in this article, dental professionals can ensure successful implant placement and fabrication of a prosthetic that meets the patient’s needs. With the All-on-4 technique, patients can regain confidence in their smile while enjoying the benefits of enhanced oral function and aesthetics.

Frequently Asked Questions (FAQs)

1. How long does the All-on-4 procedure take?

The duration of the All-on-4 procedure may vary depending on the patient’s specific dental condition. However, in most cases, the placement of implants and fabrication of the prosthesis can be completed within two days, providing patients with immediate dental restoration.

2. Are there any risks involved in the All-on-4 procedure?

As with any surgical procedure, there are potential risks associated with the All-on-4 technique. These risks include infection, implant failure, nerve damage, and bleeding. However, with proper evaluation, treatment planning, and the expertise of a skilled dental professional, these risks can be minimized.

3. How long does the conversion denture last?

The conversion denture is a temporary restoration that allows patients to experience immediate function and aesthetics while the permanent prosthesis is being fabricated. The duration of the conversion denture largely depends on individual patient factors and proper oral hygiene maintenance. The dental professional will guide patients on how to care for their temporary restoration until the final prosthesis is ready to be placed.

4. Can anyone undergo the All-on-4 procedure?

The All-on-4 procedure is suitable for many patients who have experienced significant tooth loss or are in need of full arch restoration. However, it is important to undergo a thorough evaluation to ensure that the patient’s bone density and overall oral health are suitable for implant placement. Patients with certain medical conditions or complex dental histories may require additional treatment considerations.

5. How do I maintain my All-on-4 prosthesis?

Proper oral hygiene is crucial for maintaining the longevity and functionality of your All-on-4 prosthesis. Regular brushing, flossing, and follow-up visits with your dental professional are essential. They will provide instructions on proper cleaning techniques and recommend dental hygiene products specifically designed for implant-supported restorations.
