A Simplified Dental Implant for Experimental Use Facilitating Quantitative Study of Osseointegration Quality

Abstract

The invention discloses an experimental simplified dental implant conducive to quantitative research of bone bonding quality. A head annular boss is integrally formed on the outer circumference of the upper end of a main body; three annular bosses, which are distributed in an equally spaced mode, are integrally formed on the column body of the main body, and the cross sections of the annular bosses are represented as isosceles trapezoids; three annular grooves that longitudinal sections are represented as isosceles trapezoids are formed between two bosses; notches of the annular grooves are wider than groove bottoms; and the lower end of the main body is a hemispherical body that an arc roof is located below. The dental implant disclosed by the invention is highly symmetrical, regular and simplified in structure and is easy for processing. With the design of the annular boss at the upper end, good biological sealing is provided for bond bonding on the body part; in comparison with the design of screw threads, the bosses and the annular grooves on the body part can avoid interference of the design of the screw threads on the implant to an unscrewing experimental result; and with the design of the three grooves, bonded bones, which grow in the grooves, are larger in volume, so that newly formed bones are imaged more clearly in imaging analysis, and such important indexes as a bone bonding rate and the like can be obtained more precisely through hard tissue slice analysis due to the computability of volumes in the grooves.

Description

technical field [0001] The invention relates to an implant, in particular to a simplified dental implant for experimentation which is beneficial for quantitative research on the quality of osseointegration. Background technique [0002] Since the quality of dental implant osseointegration directly determines the success or failure of the implant, the study of osseointegration quality is fundamental to the study of dental implants. Experimental dental implants currently used for osseointegration studies include two types: one is an oversimplified cylindrical implant without threads (type A implant); the other is a cylindrical or implant imitating clinical dental implants. Root-shaped implants with threads (type B implants). But there are following problems: [0003] 1. Type A implants are smooth implants without a threaded structure, and the range of newly formed combined bone cannot be calibrated. The newly formed bone tissue around the implant can only be estimated by obs...

Problems solved by technology

However, due to the shallow and irregular grooves of the implant threads, it is difficult to calculate the amount of implant osseointegration between the implant threads even through hard tissue sections, and it is also difficult to reconstruct the ideal osseointegration through the highest resolution Micro-CT in radiological examination. Newly formed bone tissue, because the amount of bone tissue in this area is low, so it is still not possible to make an accurate quantitative assessment of the quality of the implant-bonded bone

[0005] 3. In the unscrewing test of evaluating the implant bonding force, the designed thread of the B-type implant has mechanical interference on the unscrewing test of the implant. At the same time, because the designed thread does not have a uniform specification, the experimental results are difficult to be objective Compare
