The Externa® implant by BTI is characterisd by: Having a hexagon with different side and height dimensions depending on the implant platform. This design is a result of the indications of the implants, therefore, the wide platform implants will have a larger hexagon than the universal platform implants, as they are indicated for solving prostheses in areas of the mouth with greater biomechanical requirements. Simplicity and aesthetics: The Externa® system by BTI has all the prosthodontic components necessary to achieve an excellent aesthetic result, with abutments for screw-retained and cemented prostheses, and for immediate load.
