How To Connect The Crown And The Base Of The Dental Implant?

The connection between the crown and the base is a very important step in making dental implants, which is related to whether the dental implant can be successful.
There are three common connection methods:
Bolt connection (screw fixation): Similar to fixed dentures, the upper structure (crown) is fixed to the implant base by bolts, and the patient cannot take it off by himself. But the doctor can remove it and clean it when there is a problem.
Bonding: It is an easy-to-operate connection method. Zinc phosphate adhesive and self-curing resin are used to bond the crown to the base to form a fixed crown and bridge restoration. But another problem is that if there is a problem, the restoration must be destroyed before it can be removed.
Removable connection: The denture obtains retention force with various attachments, etc. It is a removable denture that the patient can take it off by himself, but the retainer part still needs to be connected to the base in a fixed way.
