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.
