Description

Mortise-tenon connection type restoration design method applied to implanting dental crowns in aesthetic region

Technical Field

The invention relates to the technical field of oral medical treatment, in particular to a mortise and tenon joint type restoration design method applied to implanting a dental crown in an aesthetic region.

Background

At present, when an anterior tooth missing implantation scheme is designed, a palatal side implantation design scheme is caused when an anterior tooth area is implanted due to the fact that labial and lingual bone absorption of an alveolar bone after the anterior tooth missing, and a long axis of an implant inclines 15 degrees towards the labial direction to implant an implantation site. However, in the second stage of restoration, the angle abutment is required to restore the crown to the normal anterior occlusal direction. However, a long screw is required to fix the angle abutment to the implant. Two crown designs have therefore emerged. Scheme 1. adhesive retention: firstly, the abutment is linked with the implant through the retention screw, and then the full crown of the prosthesis tooth is bonded and fixed with the fixed abutment by using a special bonding agent. Scheme 2. screw retention: the dental crown restoration is realized by CAD-CAM (computer aided design) and computer aided manufacturing, namely, the integrated restoration of the whole crown of the restoration tooth and the abutment in vitro is completed in a special high-temperature sintering furnace, and then the dental crown restoration is fixed on the implant through a retaining screw.

However, although the use of bonding and retaining can solve the problem of the beauty of the anterior crown, the excessive adhesive in the bonding process will flow to the lower part of the anterior gingiva and remain under the gingiva, which will greatly increase the incidence of peri-implant inflammation caused by the remaining adhesive and eventually lead to the possibility of implant failure. Although the method of using screw to fix the tooth can avoid using adhesive and the inflammation around the implant caused by the adhesive, because the fixing channel of the fixing screw needs to be reserved on the dental crown, and because the long axis lip of the implant is implanted in an inclined way of 15 degrees, the labial side of the dental crown is inevitably required to be provided with a hole, although the labial side of the dental crown can be sealed by using resin filling materials with the color close to that of the tooth after the dental crown abutment is fixed, the two methods have color difference and different refractive indexes, thereby influencing the aesthetic degree of the appearance of the anterior tooth.

In order to solve the problems of the two implantation schemes of the bonding retention and the screw retention for the missing of the anterior teeth, the invention provides a tenon-and-mortise connection type restoration design method applied to the implant crown in the American area.
