Title:
TESTING DEVICE FOR TIGHTNESS OF IMPLANT AND ABUTMENT MATING INTERFACE
Document Type and Number:
WIPO Patent Application WO/2022/032993
Kind Code:
A1
Abstract:
Disclosed is a testing device for tightness of an implant and abutment mating interface, the testing device comprising: a container, having an inner accommodating cavity, wherein the top of the inner accommodating cavity is provided with an opening in communication with the outside, and the inner accommodating cavity is filled with a liquid; a dental implant system, which is arranged in the inner accommodating cavity and comprises an implant and an abutment, wherein the implant is immersed in the liquid, the abutment is installed at the top of the implant and provided with a fitting hole penetrating in a vertical direction, and the top end of the fitting hole is located above the level of liquid; and a gas delivery device, which introduces gas into the fitting hole. According to the testing device for tightness of an implant and abutment mating interface of the present invention, the tightness of an implant and abutment mating interface is tested for screening a dental implant system with poor tightness, so as to prevent the dental implant system with poor tightness from being implanted into the alveolar bone of a human body. The present invention can be applied to dental implants.
