Dental implant with reducing thread

Abstract

The invention provides a dental implant with a reducing thread. The dental implant comprises an implant body. At least one continuous thread is arranged from the root to the periphery of the neck of the implant body. The thread pitch of the thread from the root to the neck is gradually reduced, containing grooves are formed between the two side faces of adjacent thread teeth, and the opening widths of the containing grooves are smaller than the groove bottom widths. One thread is adopted, the bone bonding strength of the implant can be improved, the adhesion rate of osteoblast is improved, proliferation and differentiation of the osteoblast implant surface in the early implantation period are obviously promoted, and the planting survival rate is greatly increased.

Description

technical field [0001] The invention belongs to the field of implants, in particular to the field of dental implants with variable-diameter threads. Background technique [0002] Dental implant restoration technology is known as the most remarkable progress in the history of dentistry in the 20th century, and it is also the fastest-growing specialty in stomatology in recent years. It is necessary to ensure that the implant has sufficient strength to offset the force generated when people chew, and it must also ensure that it can well absorb tissues such as blood, flesh and debris during implantation and use, so as to prevent the invasion of bacteria and microorganisms. Phenomena such as inflammation, loosening, and abutment shedding around the implant will affect the restoration effect of the implant. Implants should not only meet the requirements of strength performance, but also meet the requirements of biocompatibility. At present, the disadvantage of dental implants is...

AI Technical Summary

Problems solved by technology

At present, the disadvantage of dental implants is that their biocompatibility is not good. Over time, due to the invasion of bacteria and microorganisms, the alveolar bone will begin to resorb; the cooperation between the abutment and the implant will begin to loosen. The segmented thread is the thread with different pitches at the bottom and the neck, and the thread adopts a triangular thread method. The bone cells and the implant surface are in direct contact, and the bone cells need to be firmly adsorbed on the implant surface, so the surface treatment requirements Extremely high, the traditional segmented thread cannot guarantee the contact and fusion between the two segments of blood at the first time
