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.
