The Application of Root Analogy Implant in Immediate Implantation
A Clinical Exploratory Study of Root Analogy Implant
The Dental Hospital of Zhejiang University School of Medicine
10 participants
Apr 1, 2024
INTERVENTIONAL
Conditions
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.
