Problems solved by technology

The abutment and the artificial crown are retained by the adhesive, which is prone to micro-leakage of the adhesive, causing bacterial colonization, which in turn causes periarthritis, and increases the risk of implant failure

Embodiment Construction

[0029] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0030] Such as figure 1 with 2 As shown, an expansion sleeve dental implant includes an abutment 1, an implant body 2, and an expansion sleeve 3. Before the dental implant is implanted in the jaw hole, the expansion sleeve 3 is installed on the implant body 2 from top to bottom. At this time, the expansion sleeve 3 can move up and down outside the implant body 2, the implant body 2 and the expansion sleeve 3 are integrated into the planting position, and the abutment 1 is screwed into the implant body 2. The inner threaded section 24 of the implant body cooperates with the threaded section 14 of the abutment, the lower part 23 of the implant with a conical structure moves upwards for a small distance, and the inner conical wall at the lower part of the expansion sleeve 3 is forced to expand outwards, pushing the incision groove 32 to open 0.04-0...

Abstract

The invention provides an expansion sleeve type dental implant. The expansion sleeve type dental implant comprises a basal platform, an implant body and an expansion sleeve, wherein the implant body is in threaded connection with the basal platform, the expansion sleeve is movably arranged on the implant body in a sleeving manner, the surface of the expansion sleeve adopts a cross knurled structure so as to increase the friction of the surface of the tooth implant and peripheral bone tissue, and the initial stage stability is provided. Besides, the contact area of the surface of the implant body and the peripheral bone tissue is increased, the later stage peripheral bone tissue can grow into a gap of a network knurling structure so as to form a stable bone combination with the dental implant, and long-term stability is provided. A plurality of cutout grooves penetrating through the outer wall are formed in the lower middle part of the expansion sleeve; circular groove holes are formedin the upper end of the each of the cutout grooves; the lower middle part of the expansion sleeve is pushed downwards by the implant body, so that the expansion sleeve can open outwards for 0.04-0.15mm; the peripheral bone tissue is extruded to fix the dental implant, and the groove holes are dispersed in the lower middle part of the expansion sleeve to generate stress; and through the groove holes and the cutout grooves, the bone tissue can be adhered to the dental implant, so that the dental implant can be stably fixed.

Description

technical field [0001] The invention relates to a dental implant, in particular to an expansion sleeve type dental implant. Background technique [0002] Implant restoration is a common dental restoration technology. Usually, dental implants, also known as "artificial tooth roots", are made of titanium or titanium alloys and other biocompatible materials, and are implanted in the patient's edentulous jawbone. , to replace the natural tooth root and firmly support the upper crown. However, the traditional porcelain restoration technology may require the adjacent teeth to be moved, which is a destructive restoration. Therefore, the durability and stability of implant restorations are far greater than those of porcelain restorations. [0003] For implant restoration in the anterior tooth area, after the dental implant body is installed, a zirconia abutment can be installed on its upper part. The zirconia ceramic abutment has no toxic damage to the surrounding bone tissue, and ...
