Live surgery of Safe-On-Four & Hands-on practicing
Optimum use of available bone by
angled placement of implants
The SIC “Safe on Four” system is a further development of the “bar and bridge abutments” system.
In the “Safe on Four” system, the bar and bridge abutments and the “Safe on Four” angled standard abutments are directly screw retained with the respective implant. In this way, a fixed transgingival platform is created over which all further prosthetic and laboratory technical measures are completed. The system is indicated for fixed or removable bridge or full restorations with the stipulation that the distal implants can have a maximum implantation angle of 30°.
The maximum bone availability is utilised distally by displacement of the most distally placed angled implant.
During development of the system, particular value was placed on the greatest possible stability of individual components. The straight bar and bridge abutments consist of a two-part design which includes an abutment component with hex and a “Safe on Four” fixation post that, using the long screw shank, ensures maximum continuous loading capacity. The “Safe on Four” universal fixation screws also have a reinforced screw thread.

General Guidelines for SIC “Safe on Four“ Restorations:
The generally accepted rules and recommendations for dental implantology also apply here.
For complete restorations a minimum of four implants must be placed in the mandible and a minimum of six in the maxilla. The bone quality must be D3 or higher.
The implants must exhibit an intraosseous length of at least 9.5 mm and angled implants 11.5 mm.
The implant diameter should be as large as possible – minimum: 4.0 mm. The implant should be placed at 16° resp. 30°.
In case of immediate placement or immediate loading – to ensure adequate primary stability – the placement torque must be between 30 and 40 Ncm.
The secondary parts (crown bases) must be firmly splinted primarily and distal extensions should generally be avoided.
Comprehensive diagnosis and patient counselling as well as preoperative planning are essential. CT or CBCT planning is useful for determining the locations of the anatomical structures.
The opposing dentition and general patient-specific risk factors must be given special attention.
The operator must be sufficiently competent in surgery and prosthetics.
