Description

Implant Structure

technical field

The utility model relates to the technical field of oral medical instruments, in particular to an implant structure.

Background technique

With the continuous development of oral implant technology, dental implant technology is also becoming more mature and stable. Dental implant technology is to implant a titanium alloy artificial implant with high biocompatibility into the alveolar ridge, fix it, and suture it. After several months (usually 3-6 months), the implant and bone tissue form bone. After the combination, the post-repair is carried out. Because it can provide strong chewing power, it has become the first choice for patients with missing teeth.

The conventional operation of the implant in the prior art is to replace the covering screw with the healing cap in the second stage. The patient needs to open the gum under local anesthesia to replace the healing cap. The shape of the gingiva formed by cap molding is different from the real gingival shape, which cannot achieve a better aesthetic effect. At the same time, the poor shape of the gingiva can also lead to the problem of implant food impaction, which is also the main reason for the failure of the implant to fall off. First, in order to form a personalized transgingival contour clinically, doctors often need to configure an additional healing abutment with a plastic crown for shaping. dental cost. Moreover, the implant accessories in the prior art are all made of titanium metal, and the cost is high, and some accessories are disposable, which increases the clinical cost of the patient's use.
