COSTA RICA - DENTAL IMPLANTS - TORQUE TEST
Before the crown is placed on the implant, the implant is torque tested. The dental implant has to withstand a certain amount of pressure. A failed dental implant is a dental implant that could not handle the required amount of pressure without moving.
Dental Implant Being Torque Tested in Costa Rica
The benchmark is 35 Ncm's (Newton's per centimeter.) There is a special "wrench" that is set to 35 Ncm's. The final abutment is inserted into the exposed dental implant. Then the abutment is reverse torque tested at 35 Ncm's. If the implant does not move and the patient does not experience a lot of pain the implant is considered to have successfully integrated. After a successful torque test a crown can be attached to the integrated dental implant.
Another interesting approach to successful dental implant integration is the "ping" test. Not sure exactly how it is done but a dental implant that has successfully integrated with the bone will ping when tapped. A failed dental implant gives off a thud type sound.
