Degradable Dental Implant

A dental implant system using gradient degradable alloy layers to balance initial stability and long-term bone integration.

Overview

What it is

A non-absorbable implant body and thread structure is covered by degradable Zn-Mg alloy layers. At placement, the outer layer forms a sharp thread shape that aids insertion and primary stability.

Over time the alloy layers degrade in a controlled, three-stage gradient, gradually reducing pressure on the cancellous bone, releasing ions at a measured pace, and supporting healing toward durable long-term integration.

Technology & Mechanism

How it works

Thread geometry & gradient structure

Thread profile before and after degradation: the sharp degradable layer (120) over the base thread (110) dissolves to leave a rounded thread (110).
