Elderly or osteoporosis, smokers, diabetics or people who have had cancer sometimes not eligible to dental implants made of the lack of capacity of their bones properly integrate the new prostheses that replace the root.
The coating of these implants with a novel biodegradable material developed by researchers at the Universitat Jaume I, University of the Basque Country and the company ILERIMPLANT to perform implants in people with bone deficit, it will increase the overall success rate of implants through enhanced biocompatibility thereof and reduce osseointegration time, ie the bone integration.
If far titanium radicle replacing took tooth root anchored to the jawbone in a minimum of two months the developed prototype will reduce these times, so that it can be placed before the patient ceramic crown that replaces to the visible part of the tooth, and thus regain his normal life before. Julio José Suay, coordinator of the research group of Polymers and Advanced Materials UJI, explains that "this is to cover the implant with a biodegradable coating, the contact with the bone, melts and gets released this degradation compounds of silicic and other bioactive molecules that induce bone generation. "
This is a totally innovative research line for the systems used to date, for an increased roughness of the implants to facilitate their integration into the bone. In this regard, stresses that Soldent Suay is a collaborative project between academia and industry developed in the framework of the initiative "Innpacto" the Ministry of Economy and Competitiveness. "What is sought is to achieve a high level of innovation encouraging that companies and research centers work closely together. From business needs detected in this case by the patients, are redirected research and thus get disruptive innovations that are not in the markets and open new business opportunities, "he says.
For Soldent project, researchers at the Jaume I and the University of the Basque Country are working together with the company ILERIMPLANT SL in this prototype development competitively. After in vitro testing with cell cultures of different biomaterials made, we proceeded to the live animal evaluation, to achieve the best results presented prototype. In a new phase, which explains Suay proceed with the clinical assessment, so as to get the medical marketable within two or three years.
The research aims to promote the success rate of dental implants, especially those who may be deficient in his jaw. In this regard, it is noted that no replacement of a lost tooth involves a series of biomechanical problems such as change line bite, disordering of the teeth and the creation of gaps between them, which ultimately can lead to periodontal diseases as gingivitis and periodontitis spoilage clamping mechanisms of the teeth and cause the loss of more new teeth. Herein lies the importance of replacing the teeth, in addition to the full recovery of masticatory function and normal social relationships.
Dentures replacing natural teeth are composed of a titanium prosthesis root, which replaces the tooth root and to be anchored to the jawbone, and the ceramic crown, which replaces the visible part of the tooth. The prosthesis should be anchored to the bone root enough before applying mechanical load on it, which means that to date over a minimum of eight weeks can not incorporate the crown. The coating obtained by the sol-gel route researchers accelerates anchor period, so that the crown can be placed before, also avoiding the risk of infection during this time.
