Multi Unit Abutment: One Stop Solution For Many Problems

The Multi unit Abutments (MUA) are designed carefully to rehabilitate both partially edentulous and edentulous arches. It is considered a one-stop solution for many oral diseases.

Generally, dentists or oral surgeons recommend multi unit abutment placement in the jaw. Abutments work as a bridge that make teeth look better as well as enhance the oral health of patients.

Not only this, the abutments are used for many other treatments. Well, in this article, we have mentioned everything you need to know about MUA. Let's dive in!

What is MUA?

MUA is an abutment that is commonly used for coordination with full arch replacements and zygomatic dental implants. Basically, an abutment is a connector piece of metal used to connect an implant to a dental prosthetic.

MUAs are specially designed in a range of angle modifications and are available for all implant platforms. And it can be seen in different sizes.

When Are Multi Unit Abutments Needed?

The dentists believe that MUA is highly recommended and the best to overcome restorative challenges. While creating a full arch screw-retained implant restoration MUAs are the important elements. Basically, the MUAs give all abutment sites a positive uniform seat and a passive draw.

The most common need of MUAs is that it delivers a more predictable and easier seating for the last restoration. It also reduces the stress translated into the restorative system.

How To Choose a Multi Unit Abutment?

The dentists choose MUAs as per the condition of the patient’s mouth. For example, for a 1mm angled multi-units, "one angled 2mm," and "one straight multi-unit" is needed.

V-type

The V-type has the hex and a smaller cone inside the multi-unit. These are suitable if there is not enough interocclusal space, and it gives more Zirconia thickness that strengthens the crown.

D-type

The D-type abutment has an angulated version and huge cone that consist of the same sleeve.

How To Place a Multi Unit Abutment?

Check out the abutment placement instructions listed below.

For Straight MUA

• Use a Screwdriver Unigrip to remove the healing abutment and rotate it counterclockwise.

• Now, use the pre mounted plastic holder to place the abutment to the implant.

• Screw the abutment into the right place.

• Remove the plastic holder if the placement is seated.

• To verify and confirm the seating of the MUA, take a radiograph. Make sure you tighten the abutment screw to 35 Ncm by using Screwdriver Machine Multi-unit and the Manual Torque Wrench Prosthetic.

For Angled MUA (17° or 30°)

• Use a pre-mounted holder to place the abutment.

• Use a screwdriver to tighten the abutment screw till you feel resistance.

• Use a counterclockwise direction to unscrew the holder from the abutment.

• A radiograph is very important for verifying the exact seating of the abutment. Don’t forget to tighten the abutment screw to 15 Ncm.

The Use Of Multi Unit Abutment In Treatment

The surgeons or dentists recommend placing an abutment for space, height, and other issues in teeth. Read on to know when the MUAs are needed.

1. For Prosthodontic Reconstruction

The ability to choose angled or straight multi unit abutment provides higher flexibility in prosthetic reconstruction. The screw access holes are easy to the position by using angled abutments. And a right path can be developed easily to offer a passive fit of the frameworks used in full and partial-arch prostheses. The entire process is simplified as a process for prosthodontic reconstruction.

Further, the short profile of MUA permits a more significant variability in the angulations within implants. The abutments can accommodate up to 40 degrees of divergence between abutments if positioned well. And this helps in the reconstruction of prosthetics. Further, the variable collar heights of MUA let the dentist place the implant cylinders. It helps to accommodate interocclusal space and mucosal tissue thickness. The abutments' screw-retained ability allow easy access and great retrievability for future maintenance.

2. For All-On-Four Dental Implant Surgery

The concept of all-on-four treatment provides a predictable method for treating the atrophic jaw of patients. It doesn't prefer regenerative procedures, which increase morbidity. The outcomes of this treatment indicate a survival rate of 99.8% or more for 2 years.

Moreover, the MUA has an availability of a wide range of angulations and sizes. And the size the dentist chooses totally relies on the dental implant that is being used. Basically, angulation sizes provide greater flexibility to a dentist while doing all-on-four implant treatment.

0°, 17°, 30°, and 45° are some of the basic angulations used in this treatment. Still, there are some sizes like 52.5° or 60°, which are available in a few cases.

In certain cases of all-on-four dental implant surgery, the dentist suggests multi unit abutment.

3. Misaligned Teeth

There are two kinds of misaligned teeth: one is inconvenient, and the other one is unsightly. Sometimes misalignments need many years of treatment to fix; that is why dentists suggest the MUA placement.

Basically, the misaligned teeth don't look good. However, it can cause severe problems like a high risk of gum disease, tooth decay, and joint pain, and sometimes patients feel low self-esteem.

The misalignment can be divided into many types, such as; cross bite, crooked teeth, excessive spacing, underbite, crowded teeth, overbite, or open bite.MUA works as a bridge for the misalignment of teeth. Following the procedure results in making teeth look similar.

Furthermore, the abutment can be produced individually as per the shape of the tooth. The tooth crowns that are cemented onto the tooth are implant-like titanium abutments. They can bear higher loads and are even thicker. Also make the patient's teeth look aligned and attractive.

4. Spaces Between Teeth

Basically, the spaces between the teeth cause many issues for patients. If teeth are pushed out of alignment or don't grow in properly, you may see a gap in between the teeth. Sometimes the teeth are too far from each other that you can touch the empty space.

So, to solve the space issue, dentists recommend multi unit abutment. It helps to cover the gap as well as enhance the appearance.

5. Height Disparities

One more common reason why a dentist opts for MUA is because of height disparities. Usually, lower implants are placed above the tissue; however, the taller abutments are placed deep in the bones. Therefore the abutment helps all teeth to look the same height.

Final Thoughts

The multiple unit abutment works as a powerful solution for major dental issues. Right from misaligned teeth to prosthodontic reconstruction, abutments are recommended by expert clinicians.

Apart from this, for a successful dental treatment, the dental surgeon needs a few tools like; bone profiling drills or screws, scissors, titanium sections, and more. So, ensure you buy high-quality products from the right place. In the end, successful treatment requires the right tools.
