How The Process Of Multi Unit Abutment with Prosthesis Works

by janeausten

Dental implant surgery has become a popular and effective way to replace missing or damaged teeth. One of the key components in this process is abutment, which connects the implant to the final prosthetic restoration. In recent years, multi unit abutments have gained popularity among dental professionals for their speed, convenience, and cost-effectiveness. Its use with several dental prosthesis is believed to make the restoration process more efficient.

In this blog, we’ll take a closer look at what they are and the advantages they provide. We will also provide a detailed step-by-step procedure of how they are used with a dental prosthesis. Whether you’re a dental professional looking to expand your knowledge or a patient considering dental implant surgery, this will serve as a solid reference.

Let’s get started!

What is Multi Unit Abutment?

A multi unit abutment, also known as an implant analogue, is a small connector piece which is used in dental implant surgery. Its function is to connect the implant to the final prosthetic restoration, such as a dental crown or bridge. The abutment sits on top of the implant and serves as a platform for the prosthetic restoration to attach to.

The multi unit abutment has a standardized shape, size, and angulation. They are typically made out of titanium and can be used with different implant systems. However, they are generally used for full arch replacement or all-on-4 implants.

The Process of Using Prosthesis with Multi Unit Abutment

Here we have laid out a detailed step-by-step procedure:

Pre-operative Planning

The procedure starts with the dentist evaluating the patient and developing a suitable treatment plan. Radiographic images, such as a CT scan, may be taken to help determine the ideal location and angulation for the implant. The dentist also evaluates the patient’s medical history, oral hygiene, and overall health to ensure that they are a good candidate for implant surgery.

Implant Placement Surgery

Next comes the implant placement surgery which is performed under local anesthesia or conscious sedation. During the surgery, an incision is made in the gums to expose the jawbone. The jawbone is then prepared by drilling a hole to the proper depth and width to accommodate the implant. Then, the implant is inserted into the hole and secured in place with a screw or a special driver. Lastly, the implant is covered with the gums and a healing abutment is placed on top.

Healing Period

After the surgery is done, the implant is left to heal and integrate with the jawbone for a period of several weeks to several months. During this time, the dentist provides the patient with a specific post-operative care plan to ensure proper healing.

Placement of the Multi unit Abutment

Once the implant has fully integrated with the jawbone, the dentist removes the healing abutment and inserts the multi unit abutment into the implant. The abutment is tightened with a special wrench to secure it in place.

Impression Coping

In this step, the dentist makes an analogue impression or takes a digital scan of the patient’s mouth. Then, the impression of the abutment and surrounding teeth are sent to the lab where the final prosthetic restoration is fabricated. Depending on the treatment plan the lab then fabricates the prosthesis.

Prosthesis Placement

The final prosthesis restoration is placed on top of the abutment and fastened in place with a screw or cement. After that, the dentist checks the restoration for proper fit, bite, and esthetics, and makes adjustments if required. It is very likely that the patient may need to return for additional appointments to ensure proper fit and function.

Follow-up and Maintenance

After the implant and prosthetic restoration are placed, the patient will need to attend follow-up appointments to ensure proper healing and function. They will also need to practice good oral hygiene and maintain regular dental appointments to ensure the longevity of the implant and the prosthetic restoration

Advantages of Using Multi Unit Abutment with Prosthesis

In this segment, we will discuss the benefits Multi Unit Abutment offers when used with a prosthesis.

  • The primary advantage of Multi unit abutments is speed and convenience as they can be quickly and easily attached to the implant after the healing period. This considerably speeds up the overall treatment time.
  • They offer a great deal of versatility as they are compatible with a variety of implant systems.  which can make it easier for dental professionals to work with different brands and types of implants.
  • Multi unit abutments typically have a standardized shape, size and angulation, which can provide a more predictable and consistent outcome.
  • Another benefit is that they are often less expensive than custom abutments, as they are mass-produced and do not require custom fabrication.
  • It creates a level platform across implants, which allows for better restorative design and soft-tissue maintenance to be achieved.
  • Multi unit abutments make the removal of restoration simple without disturbing the soft tissues.


Multi unit abutments are a cost-effective, versatile and convenient option in dental implant surgery. They offer a standardized shape, size and angulation that can speed up the overall treatment time. The choice of abutment depends on the patient’s condition and the specific case, and the dental professional’s experience and preference. Hence, understanding the working and benefits of multi unit abutments can help to make an informed decision.
