Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, and the present invention is not limited to the following embodiments.
[0027] Such as image 3 As shown, a new dental implant of the present invention includes an implant 3 screwed to the alveolar bone, an abutment 2 screwed to the implant 3 , and an artificial crown 1 arranged on the abutment 2 .
[0028] Such as figure 1 with figure 2 As shown, the abutment 2 includes an upper abutment 21 and a lower abutment 22 with a clearance fit. A hole for installing a central screw 6 is arranged inside the abutment 2 . The upper base 21 is divided into upper and lower two cavities by the middle stopper 25, the upper cavity is used for setting the nut of the central screw 6, and the lower part is the installation cavity 24 for setting the shock absorbing assembly 4, the shock absorbing assembly 4 is a spring 44 , The upper end of the spring 44 is co...

The invention discloses an oral cavity split implanting abutment with a buffering and physiological sensory structure. The oral cavity split implanting abutment comprises an abutment body connected with an implanting body through a thread. The abutment body comprises an upper abutment body and a lower abutment body connected with the upper abutment body in a clearance fit mode. The abutment body is provided with a central screw, and the central screw penetrates through the upper abutment body and the lower abutment and is in threaded connection with the implanting body. A damping assembly used for buffering tooth masticatory force and a pressure-sensitive element used for physiological sensation are arranged between the upper abutment body and the lower abutment body, and the pressure-sensitive element is elastically connected with the damping assembly. The wire end of the pressure-sensitive element penetrates out of the abutment body and is arranged on the outer side of the abutment body. An implanting tooth can meet the requirement for daily foot mastication, simulate the masticating action of a normal tooth and transmit the masticating action to gingival nerves to generate mastication sensation.
Description
【Technical field】 [0001] The invention relates to the technical field of oral implantation, in particular to an oral cavity split implant abutment with cushioning and physiological sensation. 【Background technique】 [0002] With the continuous development of oral implant technology, "oral implant technology is becoming more and more mature and stable. Implant dentures are implanted with biocompatible titanium metal implants, and after they form osseointegration in the alveolar bone, they The upper part of the crown is installed through the connection of the implant abutment. The implant directly forms a bony connection with the alveolar bone, which can withstand a large occlusal force, but it does not have the periodontal ligament system that natural teeth have. This determines This means that it does not have the function of cushioning the bite force, nor does it have the feeling of natural teeth. [0003] Aiming at the two-stage implants that are widely used clinically at...
