A dental implant is an artificial component that replaces the root portion of a missing tooth, to which an implant crown is attached. The only visible part in your mouth will be the crown. The implant is fitted in the jaw bone through surgery.
Screws allow a fine attachment of the implant crowns to the implants. Implants must be placed in such a way as to allow implant crowns to connect to them so that the crowns pop through the gum tissues in the right direction.
Cemented Crown vs. Screw-Retained Crown
It is easier to maintain screw-retained implant crowns. They allow the implant-crown components to be more easily removed, repaired or replaced, without damaging the implant or the restoration.
It is not much of a big deal to lose the screw that attaches the restoration to the implant. In a screw-retained restoration, replacing or retightening the screw is simple and predictable. Opposingly, it is extremely difficult and time taking to do the same with remove cemented crowns.
Screws Are Safer
Screws are a safer option in some situations, such as:
Immediately Loaded Implants
It is easy to manage screw-retained crowns when implants are crowned immediately. Usually, an implant is left in place for several months to fuse to the bone before attaching a crown. But in some cases, the crown and dental implant will be attached at the same time. Here, screws offer additional benefits over cement. Sometimes patients lose their cement seal during the initial recovery period. While in some cases, the cement can cause inflammation if it flows below the gum tissues.
Provisional Implant Crowns
To develop ideal aesthetics, a customized temporary crown is required to mold and shape the soft gum tissues. The simplest method is to use a screw-retained restoration.
Screwed-in crowns and cemented ones both have pros and cons. Your dentist is the one who can recommend which option is best for you.
