New dental implants for people with bone deficit

Published on January 22, 2013 at 1:16 AM · No Comments

Elderly or people with osteoporosis, smokers, diabetics or people who have had cancer are sometimes not eligible to receive dental implants as their bones are unable to correctly integrate the new prostheses which replace the root. Researchers at the Universitat Jaume I (UJI) in Castellón have developed an implant coating with a novel biodegradable material aimed at people with bone deficit. It will also increase the overall success rate of implants through an enhanced biocompatibility and reduce the time of osseointegration or bone integration.

If so far the titanium radicle replacing the tooth root took at least two months to be anchored to the jawbone, the prototype developed will reduce the waiting so that patients can receive the ceramic crown which replaces the visible part of the tooth earlier, and thus regain their normal life sooner.

Julio José Suay, coordinator of the research group of Polymers and Advanced Materials explains "it consists on covering the implant with a biodegradable coating that, upon contact with the bone, dissolves and during this degradation process is able to release silicon compounds and other bioactive molecules which induce bone generation".

This is a totally innovative research line as the systems used to date consisted of increasing roughness of the implants to facilitate its integration into the bone. In this regard, Suay stresses that Soldent is a collaborative project between academia and industry developed in the framework of the call "Innpacto" of the Spanish Ministry of Economy and competitiveness.
