The dental abutment screw is the device that is used to secure the abutment to the implant. This fastener is threaded and is typically tightened until it reaches its final seating position. There are mechanical or electronic torque measuring devices that will indicate the magnitude of the torque that is being applied to the abutment screw. If proper tightening of the dental abutment screw is overlooked, serious challenges may arise.
One of the most common complications associated with dental implants is the unwanted rotation of the abutment screw. In addition, improperly using the abutment screw can result in deleterious effects on the bone, components of the implant itself and the final restoration result.
Dental abutment screws are available in various sizes, shapes and materials. It is imperative that the dentist performing the implant procedure be knowledgeable in the materials as well as the physical and mechanical aspects necessary to ensure a proper connection between the implant and the abutment.
