Problems solved by technology

Pre-bonding treatment can effectively reduce the formation of REC. The current pre-bonding treatment method is likely to cause pre-bonding abutment defects and air bubbles. At the same time, it is difficult to control the pre-bonding gap, and the amount of cement is easily insufficient or overflows, which reduces the pre-bonding process. The effect of treatment
However, the two-step digital preparation of the pre-bonded abutment needs to re-scan the personalized abutment and then cut it, which is cumbersome and reduces the accuracy of the pre-bonded gap.

Embodiment Construction

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] The present invention includes the following steps:

[0027] 1) The patient was placed on the healing abutment without temporary denture repair. After 2 weeks of healing, a machine-mixed polyether-silicone rubber closed-mouth impression was taken for a follow-up visit. The artificial gingiva was prepared and a super anhydrite model was irrigated.

[0028] 2) Routinely scan the plaster model, import it into the CAD system, select the orientation of the implantation area and mark the edge line, design the personalized abutment 1 and the full crown restoration 2 in the implantation area and save, see figure 1 .

[0029] 3) Use the scanning cutting function to seal the screw channel of the personalized abutment part, simulating the clinical situation of closing the screw channel, and save the sealed personalized abutment 3 and implant substitute 4 separately, see f...

Abstract

The invention discloses a method for reducing the formation of residual adhesive in the process of bonding and retaining implantation repair. The present invention obtains the pre-bonded abutment by adopting the CAD system to design the individualized abutment and the full-crown restoration, and simultaneously obtains the pre-bonded abutment by digitally cutting back the individualized abutment, thereby simplifying the steps and improving the precision. The pre-bonded abutment produced digitally and accurately can reserve a pre-bonding gap of 30~100 μm (every 10 μm) in a precise gradient according to the performance of the adhesive. To achieve a balance between cement retention and cement overflow, after pre-bonding in vitro to remove the overflowing cement, the full crown is quickly placed on the personalized abutment in the mouth to initial hardening, and the excess cement around the crown is removed, thereby avoiding Occurrence of excess cement residue.

Description

technical field [0001] The invention relates to a method for reducing the formation of residual adhesive in the process of bonding and retaining implantation repair. Background technique [0002] Implant-supported fixation repairs are mainly performed through two methods: cementation retention or bolt retention. Although bolt retention is favored for the health around the implant, due to the limitation of the long axis of the remaining alveolar bone and the direction of the implant, Especially in the aesthetic area of ​​anterior teeth, cement-retained implant restorations cannot be completely replaced. In addition, cement-retained restoration has the advantages of maintaining the integrity of the tooth shape, avoiding occlusal penetration, strong aesthetics, and reducing chairside operation time. Therefore, cement-retained implant restoration still has a wide range of clinical applications. [0003] The main defect of cement-retained implant repair is the residual cement, w...
