CONELOG SCREW-LINE surgical procedures

6 CONELOG ® SCREW-LINE IMPLANT The planning of implant-prosthetic reconstruction requires a team approach and a high level of attention to detail and clinical experience of all concer- ned. This is equally true for the restorative dentist, the surgeon, the dental technician, and the dental office support staff such as the nurse, hygienist, and chair side assistant. The following aspects should be taken into account during planning: LEVERAGE RATION ON IMPLANT The loading of the implant-bone interface is determined by the leverage ra- tio from the osseointegration-related resistance to the prosthetic load arm (equal to the supracrestal implant length plus crown length from the implant shoulder). If the implant length (IL) is less than the length of the crown (CL), measures must be taken to reduce loading (e.g. using prosthetic splints). The ratio of crown length (CL) to implant length (IL) should be 0.8:1 maxi- mum. IMPLANT POSITION PLANNING IL (Implant Length) CL (Crown Length)
