BTLock System for traditional implantology, Next Generation System, is created around BTLock patented connection (BTLock Locking System) and was developed in order to provide professionals with the widest application area and a full range of prosthetic solutions. BTLock research has developed different facets of the Next Generation System, with special focus on:
- Fixture Shape (periodontal neck, shape and thread)
- Colour Code
- Osseointegrating Surfaces
- Size Options
- Packaging
BTLock prosthetic parts, are replicated with all the implant lines (being the diameter equal), providing one of the widest range of options in the market (150 options, among them: castable, standard, angled, aesthetic, aesthetic angled, shoulder, overturned conical, screwable, threaded, UCLA, transmucosal, passive, zirconium, and overdenture in 5 different diameters and various options for the transmucosal neck’s height), for every kind of restoration (single, multiple, bar-retained, and overdenture) and for every type of technique (one or two stages). The accessory part is complete and easy for clinical use. Considering that a too wide choice may cause confusion in day-by-day practice, the instrumentation features essential characteristics to allow a better use, such as colour-code (for a quick diameter identification) and laser markings on the drills (to identify quickly the necessary depth).

BTLock fixture-abutment Locking System was created with the co-operation of implantologists, technicians, and engineers. The system is internationally patented and defined as ‘twice anti-rotational, asymmetric, multi-leveled internal connection ’, features three concavities asymmetrically milled on three of the six sides of the internal hexagon. The connection is 2.96 mm. deep. This kind of original connection between fixture and abutment allows a better tightening and a better distribution of chewing forces. Micromovements are reduced to the minimum. Micromovements are usually responsible for deformation of traditional hexagon, with loosening or even failure of the through screw. Another original and exclusive feature of the system is the conical bevel on the fixture with countershape on the abutment. These two elements allow a perfect matching between fixture and abutment, without exceeding profiles, or gaps. This high precision avoids any fluid infiltration or stagnation and firmly contributes to reduce the danger of periimplant sulcus, inflammation caused by bacteria. The advantages of BT Lock connection are the followings:
- Double anti-rotational level and high mechanical stability of the connection.
- Abutment positioning without need of intra-oral radiograph to verify the right position.
- Strong tightening between fixture and abutment, which provides stability and strength to the implant and avoids high stress on the through screw.
- No fluid or bacteria penetration and then optimum peri-implant hygiene.
- Decrease of “V-shaped” re-absorption on the cortical.
