The Application of Root Analogy Implant in Immediate Implantation

A Clinical Exploratory Study of Root Analogy Implant

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 10 (estimated)
• Sponsor: The Dental Hospital of Zhejiang University School of Medicine · Academic / Other
• Sex: All
• Age: 20 Years – 60 Years
• Healthy volunteers: Accepted

Summary

The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery.

Detailed description

The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery. A 3D printed personalized root implant system jointly developed by Zhejiang University School of Medicine Affiliated Stomatology Hospital, Zhejiang University School of Mechanical Engineering, and Hangzhou Ya Natural Technology Co., Ltd. The implant part of this implant system is implanted into the bone using laser melting printing technology in additive manufacturing methods. The raw material is pure titanium powder, and research results in New Zealand white rabbits and beagles have confirmed that the implant has good bone bonding ability, which can shorten surgical time, reduce surgical frequency, compress implant cycle, restore chewing function, and other advantages. The relevant research results have been published in the top oral journal Journal of Dental Research, and the chemical composition and biological safety of the material have been tested by the Zhejiang Medical Device Inspection and Research Institute (test report number: Z20221903), Z20222527，G20233158）。 The base and other accessories are cut from titanium rods using conventional reduction manufacturing techniques.
