Description
Technical Field
The invention relates to the field of oral medical instruments, in particular to an auxiliary device for external bonding of a dental implant crown and an abutment and a using method thereof.
Background
Since the 'osseointegration' theory created by the teaching of Branemark lays the theoretical foundation for dental implant, the dental implant technology is rapidly developed and widely applied, a series of problems caused by clinical tooth loss are solved, and the method becomes one of the most ideal current restoration methods.
The retention mode of the implant prosthesis mainly comprises intraoral adhesion retention and extraoral adhesion retention.
The conventional intraoral adhesion and retention method is a method of fixing an abutment to an implant by intraoral screws and then adhering a crown to the abutment. The method comprises the following specific steps: fixing and repairing the abutment on the implant by using a central screw (the torsion reaches 30N.cm), then placing a small cotton ball and a filler above the central screw head of the abutment to protect the central screw channel of the abutment, and then adhering and fixing the prosthesis on the abutment.
The external-oral cemented fixation method is a method in which a crown is cemented to an abutment outside the mouth to form an integrated crown (bridge) of the abutment, and the integrated crown (bridge) is fixed to an implant by screws. The method comprises the following specific steps: opening a round hole with the same diameter as the central screw channel of the abutment on the occlusal surface or the lingual fossa of the dental crown, then filling a small cotton ball and a filling material in the central screw channel of the abutment, then bonding and fixing the dental crown and the abutment in vitro into a whole (called the integral crown of the abutment or the integral bridge of the abutment), then taking out the cotton ball and the filling material filled in the central screw channel of the abutment, cleaning up the adhesive overflowing from the central screw channel of the abutment and the connection part of the abutment and the prosthesis, and then fixing the integral crown of the abutment (the integral bridge of the abutment) on the implant by using a central screw (the torque reaches 30 N.cm).
There are many disadvantages associated with conventional intraoral adhesive retention methods, such as: 1. incomplete cleaning of the adhesive causes peri-implantitis; 2. the looseness of the abutment retention screw is not easy to be perceived, thereby causing the breakage of the abutment and the breakage of the prosthesis; 3. once any problem occurs, the prosthesis is not easily detached, etc., and thus, the conventional intraoral adhesive retention method is gradually eliminated in clinical practice.
Compared with the mode of bonding and retaining in the mouth, the method for bonding and retaining outside the mouth is safer, and the adhesive can be cleaned up, so that the occurrence of peri-implantitis is reduced; the prosthesis is convenient to disassemble and easy to replace, so that the success rate of long-term repair is improved, and the prosthesis becomes a mainstream method for planting repair at present.
However, in a large number of clinical practices, it is found that the extraoral adhesion retention method takes time and labor to take out the cotton balls and fillers in the abutment holes and clean the adhesive overflowing into the abutment holes in the process of adhering the prosthesis and the abutment body outside, thereby reducing the clinical work efficiency.
