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.
• Fixation Screw “Safe on Four“® with reinforced thread M 1.6 mm
• Centring fit between post and abutment
• Precision hexagon provides a reliable implant / abutment connection with maximum stability
• Long screw shaft with maximum fatigue limit

SIC Planning Guide for SIC “Safe on Four”
to visualize the restoration and determine the implant alignment in relation to the angulation (mesial/distal).
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, with a minimum of 4.0 mm. The implant should be placed at angles of 16° or 30°
• In cases of immediate placement or immediate loading, to ensure adequate primary stability, the placement torque must range between 30 and 40 Ncm.
• The secondary components (crown bases) must be firmly splinted primarily, and distal
extensions should generally be avoided.
• Comprehensive diagnosis, patient counseling, and preoperative planning are essential.
CT or CBCT planning is recommended to accurately determine the locations of anatomical structures.
• Special attention must be given to the opposing dentition and patient-specific risk factors.
• The operator must be sufficiently competent in surgery and prosthetics.
