Problems solved by technology

Although the commonly used artificial bone powder hydroxyapatite has good biocompatibility, its fracture toughness is low, only 0.7-1.3 MPam, and it is easy to form oxyapatite due to high temperature dehydration, which is difficult to apply in dental implants.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] figure 1Shown is the anterior dental implant of the present invention, including implant 1 and abutment 2, the anterior dental implant is a thin implant of Ф3.8~Ф4.5mm, adopts a non-embedded structure, implant 1 and abutment 2 is a whole, the upper part of the abutment 2 is the abutment rod 2.1, the lower part is the foundation pile 2.3, and an enlarged base plate 2.2 is arranged between the abutment rod 2.1 and the foundation pile 2.3. The abutment rod 2.1 has a taper of 1.5 degrees and a length of 5-7mm, which is used for inserting and bonding the crown. The minimum diameter of the anterior tooth implant must reach Ф3.8 mm, so as to ensure that the foundation pile 2.3 of the abutment 2 has a solid diameter of ≥ 4 mm to prevent brittle fracture. In addition, in order to increase the strength of the foundation pile 2.3, the gingival part of the foundation pile...

Abstract

A dental implant made of zirconia ceramic-fused-bioactive glass ceramic artificial bone dust and a preparation method therefor. The implant is of a non-embedded structure and is integrated with a foundation. The upper part of the foundation is provided with a foundation pole, the lower part of the foundation is provided with a foundation pile, and an expanded base plate is arranged between the foundation pole and the foundation pile. When the implant is an anterior tooth implant, the gum-penetrating part of the foundation pile is also provided with an expanded bamboo joint shaped foundation pile joint. The body part and the root part of the implant are provided with threads, the thread of the body part is a shallow trapezoidal thread, and the thread of the root part is a deep triangular thread. The under-neck part of the implant, implanted into an alveolar bone, is fused with bioactive glass ceramic artificial bone dust. The implant has a reasonable design structure, is difficult to break off, has better biocompatibility compared with a pure titanium implant, and has higher bone combination intensity compared with a hydroxyapatite coated implant.

Description

technical field [0001] The invention relates to a metal-free zirconia all-ceramic artificial tooth implant, in particular to an artificial tooth implant with bioactive glass ceramic artificial bone powder fused on the surface of zirconia ceramics without damage, belonging to the technical field of dental medical instruments. Background technique [0002] In the past 30 years, titanium implants have dominated most of the dental implant field. However, titanium implants are easy to see through the metal color for thinner gums, which affects the appearance. Another problem that cannot be ignored is that according to foreign stomatological reports, in titanium implants The accumulation of titanium particles was found in the lymph node adjacent to the implant, which is a potential allergen. In addition, titanium is easy to oxidize. According to the National Natural Science Foundation project 31200756 Shandong Provincial Higher Education Science and Technology Project J12K54 and N...
