Objective and observed NecessitiesObjective and observed Necessities

Objective: Be one of the leaders in the market of the production of osseous tissue replicaand/or soft parts, and the production of implants of customized osseous tissue, from Computerized Axial Tomographies, X-rays film or MRI

Action Areas:

1ª.- The development of techniques in the preparation and study of surgical operations, which allow the surgeons, by using biomodels, made by techniques of Rapid Prototyping, to improve surgery, reducing surgery time.

2ª.- The decrease in the number of further operations and their duration due to the manufacturing of customized implants (Biocompatible materials), and to the use of Rapid Prototyping techniques which enable the surgeon to set implants as soon as possible

3ª.- the development of new bioactive technologies in the manufacturing of implants, which strengthen the osteointegration of the bone with the implant.

Replica Stage I:Getting physical Replicas in 3D, within a maximum of 2 weeks, of tissue, osseous or soft, or a

combination of both, so that the doctor can:a) Have a precise idea of the condition of the patient.b) Plan the appropriate surgical intervention.c) undertake the intervention.

Biocompatible, not bioactive implants Stage II:Utilising the same technique used to produce replicas, with the same deadlines, we produce

implants with biocompatible and implantable material. This enables:a) to obtain personalized implants according to the need of the patient.b) The abolition of parallel interventions to obtain osseous fragments.c) A reduction in the time of intervention and of the patient recovery time.

Biocompatible and Bioactive Implants, Stage III:This is based on the same principle, but we include bioactive components (e.g. mother cells,

etc.) which allow integration, with a more effective and faster cure.

The production process:

Stage IFrom the CAT, resonances, etc., the hospital sends a 3D model on a magnetic support for further treatment by Osteomodel � We use a specific protocol for the production of these files for the radiologists.Sending the CD or the files to Osteomodel ftp site ([email protected])Data processing of the gathered images, for their transformation into a cloud of dots (3D image, STL format ), which will be utilised by the manufacturing system. (SW: Mimics) Introduction of the treated images into the production system, for the manufacture of the replicas by stereolithography (SLA of 3D System), plastic sintering (SLS) and other technologies (Objet).

Stages II and IIIFrom the image transformed into cloud of dots, we obtain the negative of the osseous zone to treat (SW: 3-Matics) �By transmitting the information to the machine, we will obtain a first plastic implant for the surgeon to test with the replica produced before. (The points of fixing will be thus determined, if necessary, by the surgeon)After the surgeon has checked the implant manufactured beforehand with the counterpart, we will proceed to the manufacture of the final implant (with a biological load (Stage III) or not (Stage II)). (Metal Sintering or machining (Titanium or Peek)).
