Abstract

The invention relates to the technical field of artificial tooth roots, and provides a dental department implant. The dental department implant comprises integrated neck thread body and cone thread body from top to bottom. The end face of the top of the neck thread body is provided with a limiting part. The invention further discloses a method for verifying the binding ability of a dental department implant to bone. The method comprises torque testing, Micro-CT analysis and histological dyeing, and comprises steps of grouping animals, making a specimen and testing torsion and the like. According to the provided dental department implant, the end face of the top of the neck thread body is provided with an anti-torsion structure of the limiting part, so as to prevent a base station from being loosened, and ensure long-term, safe and reliable connection of the base station. In addition, the provided method for verifying the binding ability of the dental department implant to bone is capable of providing a scientific basis for quality detection and verification of the dental department implant.

Description

technical field [0001] The invention relates to the technical field of artificial tooth roots, in particular to a dental implant and a method for verifying its ability to combine with bone. Background technique [0002] 1952 Sweden A titanium alloy was implanted into the iliac bone of a rabbit, and a strong combination of titanium and bone was found, and experimental research on the application of titanium to dental implants began in the early 1960s. 1965 Titanium implants began to be applied to the implant treatment of dentition loss. In 1976, Schroeder in Switzerland clearly confirmed the existence of osseointegration in histology for the first time. In 1977, he reported the successful implant treatment and formally proposed "osseointegration" ( osseointegration) theory. The development of dental implantology has gone through three stages: 1. Based on the experimental results. 2. Driven by expanding indications. 3. Based on clinical evidence. [0003] Implant syste...
