A Brief Guide to Multi-Unit Implant Abutment


An excellent dental implant act appears and feels like the original teeth. There is a wide range of dental treatments available for patients, such as retained dentures, direct to fixture implants, multi-unit dental implants, or overdenture implants.

A Brief Guide to Multi-Unit Implant Abutment

To clear all the queries, we have created a guide about the multi unit abutment. It will help you in understanding the details and working.

Before we deep dive into Multi-unit abutment, let’s find out the meaning of general dental abutment. So, abutment is a major component for the restoration of a dental implant. It provides a connection between the prosthesis and the dental implant.

It is formed from a durable, biocompatible material which is titanium often. But some abutments formed surgical-grade stainless steel, zirconia, cast gold, and polyether ether ketone (PEEK).

The prosthesis is easy to turn out with the abutment. Even it doesn’t need further disrupting the healed tissue and removing the implant.

Understand Multi-Unit Implant Abutment

Basically, MUA (multi-unit abutment) is used in different implant scenarios. The whole mouth arch is replaced with a multi-unit implant abutment.

Also, it is used with zygomatic implants. It gets implanted and anchored to the zygomatic bone. This is a very beneficial implant scenario.

While replacing the whole arch, multiple implants are embedded in the jaw of the patient. For attaching the overdenture, its important abutments angled appropriately. It helps the prosthesis, and it is where multi-unit abutments come in.

The quartet of MUA’s is all-on-4 restoration. Secondly, the restoration is all-on-6 and all-on-8. Here it is six and eight implants, respectively.

You will find multi-unit abutments in a wide range of sizes and angulations. And the option for these MUA characteristics relies on many factors, which include the intra-oral environment and the kinds of dental implant of the patient.

Two types of multi-unit abutments

There are two categories of the MUA’s types, one is straight and the second is angled multi-unit abutments.


The problems like different tooth alignments or angulations varying bone type can make the requirement for various abutment angulations over a single multi-unit restoration. Furthermore, in such cases, straight multi-unit abutments are not suitable for specific implant sites. So, you rather use an angled multi-unit abutment.


Usually, this type of abutments is specifically angulations. It is found across many implant brands, such as; 17°,0°, 45°, and 30°.

It might come across a few general sizes reserved for special restorations. The Special size includes 60° and 52.5°. Dentists can make a specialized restoration system specifically for every patient as per their special requirements.

How to use a multi-unit abutment

After post-surgical healing of the implant site, you can do the placement of the multi-unit abutments. And at this moment, you can take an impression of an important prosthetic.

So, below we have mentioned a few steps for placing the multi-unit abutment.

Step : 1

Use a screwdriver to remove the healing abutment and use counterclockwise rotation.

Step : 2

Use the right tool, and try to screw the abutment in the implant till you feel the resistance. However, don’t try to tighten the screw.

It’s the most important step to check if the fitting of the abutment is right. So, perform a radiograph to confirm the abutment fixes properly in the implant.

Step : 3

When you confirm the abutment seated accurately, it is easy to be tightened.

Step : 4

In the fourth step, it is time to get an oral impression. You can either take a digital impression or a standard impression with the help of an intraoral scan. It generally happens in the case when performing with CAM/CAD equipment.

It allows the laboratory or dentist to create the important prosthesis. The situation has to be, making the correct adjustments or a new restoration of the prosthesis (already existing) to transfer it from a denture or traditional bridge to an implant-supported system.

Step : 5

Suppose you are making the prosthesis (whether sent to a laboratory or prepared in-house), connect either a healing cap or a temporary restoration to the multi-unit abutment.

Have you ever thought about why a dentist uses MUA’s over a standard abutment? As we have mentioned before, the multi-unit abutment’s angulations can support an intra-oral topography. It is extremely beneficial for patients with uneven or misaligned teeth.


In conclusion, we assure that a multi-unit implant abutment is a game-changer to an overdenture prosthetic system. It can work to support a single overdenture unit.
