Basic knowledge of multi-unit abutment

Multi-Unit Abutment

A dental implant and a dental prosthetic are connected by abutments, a little metal connecting component. Additionally, a dental prosthetic can be changed out using abutments without removing the complete implant. Specialized abutments known as multi-unit abutments (MUA) are frequently used in conjunction with full arch replacements, also referred to as all-on-four dental implants, as well as zygomatic dental implants.

A range of sizes and angulations are available for MUA. The kind of dental implant being utilized will determine how big they are. The most frequent angulations used for MUA are 0°, 17°, 30°, and 45°; however, in specific circumstances, specialty sizes like 52.5° and 60° are also available. When installing all-on-four implants, the various angulations available provide your implant dentist more flexibility.

MUA are not always necessary for all-on-four dental implant surgeries, but in some circumstances, they may be suggested or even required. The fact that MUAs can be employed in patients who have mild dental misalignments is a frequent reason why your implant dentist may advise or demand the insertion of a MUA. In the end, leveling the restoration may be achieved by positioning various MUAs at various angles.

Due to height inequalities, your dentist may use MUA as a treatment option as well. When there are height differences, shorter implants should be positioned higher above the tissue, and longer abutments should be positioned farther into the bones. This aids in achieving a single, uniform height for all abutments.

This not only gives the finished product a considerably more polished appearance, but it also balances the restoration so that any force is dispersed equally. This ensures that the repair lasts for a longer period of time and retains the ability to eat and speak.

MUA are inserted following the placement of the permanent restoration and healing of the implant site. The healing abutment must first be taken out, which is an easy process given how accessible the multi-unit attendant is. The chosen abutment will then be inserted into the implant before being measured for fit. The abutment will be tightened in place after the fit is verified.

The next step is to take a dental scan or oral imprint of the mouth in order to order the required prosthetic. An implant-supported denture or bridge can occasionally be made from a conventional denture or bridge. In other instances, though, your restoration might just be starting from scratch.

Using MUA has benefits and drawbacks, just like anything else. Before undergoing implant surgery, you should discuss these with your implant dentist to be sure you're choosing the greatest choice for your smile.

Benefits of Multi-Unit Abutment:

allows for the placement of dental implants in the jaw without a sinus lift being necessary, which can save time and money.

The MUA's angulation might give the dental prosthetic better support.

enables the coordination of the usage of several implant systems

Multi-Unit Abutment Drawbacks:

Because they are so small and have so few threads, they can be challenging to tighten.

can become slack and require retightening.
