3D-MESH

Titanium meshes are used in GBR procedures to favour the regeneration of bone volumes. They are usually associated with the usage of chips of autologous or heterologous bone or synthetic biomaterial. The assessment of the type of defect and suitable surgical skills in managing soft tissues are fundamental elements in achieving successful surgery.

CONE BEAM CT AND PRODUCTION OF A 3D VIRTUAL BONE MODEL

The fundamental requirement is a Cone Beam CT of the jaw, with a special focus on the area with the defect. The process starts with the acquisition of the patient’s tomographic examination. The DICOM file is sent by the clinician to the BTK TEAM using the Web, for the beginning of the design phase (http://upload.btk.dental/btk3d).

DIGITAL PROCESSING OF THE 3D-MESH STRUCTURE

Based on the patient’s situation, the device is designed using the CAD modelling software within the framework of a fully digitalized work flow. The morphological and dimensional features of the device and the position of the holes for the cortical screws are specifically designed so as to fit the patient’s anatomy, while preserving the noble structures. The outcome of the 3D-MESH structure is shared with the prescribing dentist, who can make changes and who confirms it before production takes place.

TITANIUM
LASER MELTING – 3D PRINTING

After receiving the dentist’s prescription, BTK produces the component by means of the “Selective Laser Melting” technique. Homogeneous layers of highly pure titanium powder are molten using a laser in a selective way, based on the virtual 3D model. The final object meets high purity and microstructural homogeneity standards that guarantee high mechanical performance.
On request, it is also possible to deliver the bone model and a copy in resin of the regeneration mesh made by means of 3D printing.

CLEANING, DECONTAMINATION, PACKAGING AND SHIPPING

After the surface is electro-polished, the product is decontaminated and packaged, ready for sterilization in the clinician’s office. All BTK production cycles are controlled and registered so as to guarantee the traceability of the product, in compliance with the most restrictive standards of reference.

SURGERY AND SURGICAL APPLICATION

The surgery is performed under local anaesthesia or conscious sedation. The device must remain in situ for the time established by the clinician, in function of the patient’s clinical situation, to guarantee correct bone regeneration. After this time period, the device must be surgically removed and then the placement of dental implants is considered, provided that the right clinical conditions are met.
