Dental implants can be replaced at any time, but it is not recommended that the crown be replaced at any time if there is no problem with its suitability. Dental implant consists of implant, abutment, retention screw and crown, etc. The implant is bonded to the bone and other components are fixed to the implant, so the crown can be removed at any time for replacement.

Whether the implant needs to replace the crown, it is recommended to timely follow-up, listen to the doctor’s advice, do not take the liberty to ask for the replacement of the crown, in order to avoid adverse consequences.
