For many individuals who are completely or partially edentulous, implant-supported overdentures provide a life-changing choice. The stability of the restoration is improved when dentures are attached to an osseointegrated dental implant. This provides for better function and higher confidence that the dentures will stay in place while the wearer is speaking, chewing, or doing any other activity.
There are a variety of methods available for attaching the dentures to implants. Although the clinical scenario and the patient's anatomy influence the decision, the technician can make the best choice for the case at hand and design the restoration to fulfill the case's functional and cosmetic criteria by having a thorough understanding of attachments.
Here are some advantages and disadvantages for five various types of attachment in light of this.
It entails creating a restoration that will be screwed directly to implant abutments, making it the "most-fixed" variety of fixed removable.
Establishes a solid link and offers the best restoration stability.
Suitable for use without a metal or bar substructure
The patient cannot remove the restoration.
Structural or esthetic issues might arise from screw access channels.
These adaptable attachments have a male ball that is typically fastened to an implant bar or directly to implant abutments. The repair has built-in female o-ring attachments that let it to lock onto the balls.
The position and direction of the attachments can be designed in a variety of ways.
Patients can easily take out and change the equipment
Needs enough room so that the ball may totally occlude the gingiva
O-rings for retention devices or other parts deteriorate over time and need to be changed.
These have a low-profile, cylindrical male component that is similar to a ball attachment, and a cap-style female that clips the restoration to the attachments.
Restorations are simple for patients to put and remove.
Nonparallel implants can support angulated connections with attachments.
When vertical space is restricted, the low profile makes it easy to utilize.
They can't be used when a firm restoration is needed because they allow some movement.
Over time, connectors deteriorate and need to be replaced.
The dentures have a channel that fits around the implant bar and is secured to the implants with screws in this attachment technique. The channel has plastic or metal clips in it to promote retention.
Offers good stability and retention.
Bar does not have to be built into the dentures themselves, which facilitates replacement.
The bar needs to be made to fit clips.
more accuracy is needed in the design and manufacturing
These attachments include equivalent magnets that are affixed to the denture and magnets that are attached to the implant abutment or screw-retained bar.
The appliance is simple to insert and remove.
Suitable for non-parallel implantation
Low profile for limited vertical space
Sometimes retention is less strong than other attachments
Over time, magnets may corrode or lose their strength.
