Technical specifications of BTI Implants
The BTI implant
BTI offers a complete range of products that adapt to many clinical situations thanks to a wide variety of titanium implants of several diameters and lengths, specially designed to be surgically implanted in the maxillary or mandibular bone.
The system also includes prosthetic elements to be coupled to the implants, and auxiliary elements for surgical and prosthetic procedures.
This versatility facilitates the planning of the surgical procedures and reduces the appearance of unforeseen events.
Transporter with depth marks and with the reproduction of the connection on the same, to control its positioning.
Two connections: Interna (tetra-lobed with no sharp edges with a good load distribution) and External (hexagonal with different lateral and height measurements depending on the platform, in accordance with the biomechanical requirements). Three different platform diameters with a wide range of prosthetic components, which enable all types of prosthodontic restorations.
Evolution is UnicCa®
The surface of the new range of BTI implants is chemically modified with calcium ions. The calcium ion has decisive functions in all of the biological processes of bone regeneration. In addition, the surface is adapted to the different tissues in contact with the implant to promote and accelerate osseointegration.More information
There are two possible apexes for BTI implants:
1. A conventional tapered apex with great advance/drive capacity, large osseointegration surface and little compression.
2. A cylindrical apex with a lower advance/drive capacity adapted to obtain good initial stability without compression in anatomical areas where significant injury to structures is possible (maxillar sinus and dental nerve). Designed for extra-short implants.
A tamper-proof plastic package that retains its leak-tight seal, endurance and sterility; suitable for the new UnicCa® surface.
On the inside it comes with a plastic pincer which retains the implant and cover screw.
Exclusive BTI controls in the manufacturing process
The properties of BTI implants unicCa® surfaces are due to special care in choosing the raw material and establishing checkpoints exclusive to BTI in all stages of manufacture of the implant, from the mineral to the final packaging.
For the manufacture of its implants and components, BTI selects the best material, monitoring that it has:
- Optimum chemical composition
- Optimum mechanical behaviour
- Optimum microstructure
- Optimum cell viability
Extracting and obtaining titanium
Titanium is obtained by reduction from minerals found in the Earth's crust. After a process of smelting and consolidation, the titanium ingot is obtained with which the semi-manufactured product in the form of bars will be shaped.
Control point 1. Purity
BTI imposes a maximum limit of impurities in the titanium ingot far below that established by the standard ASTM-F67 for titanium for biomedical use, obtaining a purer and therefore more biocompatible primary titanium.
From the titanium ingot, the intermediate products are hot forged and gradually passed through rollers to obtain the semi-manufactured product in the form of bars.
Control point 2. Composition
BTI imposes a maximum limit for the presence of hydrogen three times lower than that established by the standard ASTM-F67 for titanium for biomedical use, obtaining a primary titanium that is less brittle.
Control point 3. Mechanical resistance
BTI uses a titanium that is mechanically drawn with a special process that increases its mechanical properties by up to 30%.
Control point 4. Microstructure
BTI certifies that the microstructure is suitable for the manufacturing process by means of metallographic certificates that account for size and the orientation of the grains of the material.
Control point 5. Biocompatibility
BTI evaluates the biocompatibility of the raw material according to the Standard ISO 10993-5 Biological Evaluation of Medical Devices - Part 5 thus certifying the medical safety of the material used to manufacture implants and components.
BTI certified material
Before accepting a titanium bar for use in the manufacture of implants and components, in addition to the compulsory dimension and structural checks, BTI carries out an exclusive biocompatibility evaluation. Thus, BTI is the only implant manufacturer that ensures the material used is 100 % biocompatible and optimum for use in humans. In addition, this evaluation allows BTI to choose, from among all possible materials, the one that offers the best biological results. In this way, implants and BTI components are manufactured with the most favorable titanium for regeneration.
From the Bar to the Implant
Control point 6. Design and tolerances
After machining the shape of the implant, BTI monitors and verifies that the biological design is suitable, with a precision of 1 µm.
This control makes it possible to ensure the optimum fit of the parts, which makes the BTI system a harmonic and hermetic assembly, with the best biomechanical function and with no risk of infiltrations.
Control point 7. Topography, roughness and porosity
BTI assesses that the surface topography is suitable, and that the micro and nanometric design complies with the biological adaptation requirements established, with a reduced roughness in the neck and moderate roughness in the valleys and the turns of the thread and, in addition, with porosity for the bone to anchor itself to the turns.
In addition, BTI quantitatively evaluates the roughness of the implants to verify that they are within the correct range.
Packaging and sterilisation
All the implants are cleaned, prepared and packaged in a clean room, in clean and monitored atmospheric conditions.
Control point 8. Surface chemistry
BTI monitors that the surface is free of contaminants and that the chemical composition fulfills the established biological requirements.
