Three ways of connecting the crown and the abutment of the dental implant
We have all heard about dental implants, but when it comes to the structure of dental implants, it is estimated that many people do not know much about it. In fact, dental implants are not a whole implant, but are composed of three parts: root, abutment, and crown. The connection between the crown and the abutment is an important step in the implant surgery. The quality of the connection plays a key role in the success or failure of the implant, so how is the crown and the abutment of the implant connected?
There are three types of commonly used connection methods:
(1) Bonding: Use zinc phosphate cement, self-curing resin, etc. to fix the superstructure to the abutment of the implant. If the denture is also integrated with the superstructure at this time, a fixed crown and bridge restoration will be formed. The advantage of this connection method is that it is easy to operate and has a good retention effect. The disadvantage is that once a problem occurs, the restoration must be destroyed before it can be disassembled.
(2) Bolted connection: The upper structure is fastened to the implant abutment by prefabricated bolts. The patient cannot take it off and wear it on his own. It can function like a fixed denture. When problems arise, the doctor can remove it, and it can be removed periodically for a thorough gingival cleaning.
(3) Removable connection: The denture obtains retention force with double crowns, various attachments (bar clip, bolt channel, ball clip), magnetic attachments, etc. .The patient can wear it on their own to become a removable denture. A portion of the retainer often still needs to be attached to the abutment in a fixed manner.
