Multi-Unit Abutments: When and How To Use Them

mm Written by Andrew Sedler

Multi-Unit Abutments at Burbank Dental Lab

When restoring a full arch, screw-retained implant prosthetic case, even a minimal disparity in the draw of the implant interface access causes restorative challenges. The use of multi-unit abutments can overcome restorative challenges and is highly recommended (if not required) when creating a full arch screw-retained implant restoration. Multi-unit abutments (MUA), are designed with a range of angle correction and are available for virtually all implant platforms. Multi-unit abutments provide a passive draw and positive uniform seat for all abutment sites.

Prosthetic Restorations That Benefit From Multi-Unit Abutments

Procedures and Steps For Using Multi-Unit Cases

Many clinicians place multi-unit abutments at the surgery appointment and convert a denture into an implant-retained prosthetic. This is always best done by placing appropriate multi-unit abutments and adapting the denture to the multi-unit abutments. However, if you choose not to immediate-load the implants, it is always best to seat the multi-unit abutments before the initial impression as you begin the restorative process. If you begin the impression process with multi-units placed and take your impressions at the multi-level rather than implant level, it saves you steps later and enhances the accuracy of the final prosthetic’s fit.

3 Issues To Be Aware of When Restoring Using Multi-Unit Abutments

The advantages of using multi-unit abutments far outweighs any of the concerns mentioned regarding the above issues. You will have a much easier and more predictable seating of the final restoration. You will also create reduced stress translated into the restorative system due to the passive nature of the seating process of multi-unit abutments. Additionally, each time the patient has a recall appointment, it will be much easier to remove and replace the prosthesis.
