International Dental Course

International Dental Course of Implantology with Dr. Georg Bayer

in Landsberg am Lech, Germany

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 a 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 utilized distally by displacement of the most distally placed angled implant.  


During the 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.

Course Topics


  1. Observation and explanation of implant surgery of Safe-On-Four

  2. Prothestic solution of SOF (impression copy, making temporary & permanent denture, milling technique, 3D printing, etc.)  

  3. Clinical case sharing

  4. Hands-on practicing on models

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  counseling 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.
