Dental Implant Torque

For final tightening of the dental implant, torque ratchet is used. It is also used to measure the exact torque of the dental implant. Over threading is also prevented by using the torque ratchet. Over threading could strip all threads in bone.

Dental Implant Fixture Installation

The dental implant fixture mount is attached to the fixture using the open ended wrench. The inner hexagonal surface should fit properly over the fixture head. Match the inner surface of the handpiece connector to the square top of the fixture mount and apply gentle pressure between the components.

Dental Implant Fixture Parallelism

The direction indicators are inserted into the dental implant site to check and maintain parallelism during preparation.

Poor fixture alignment

If the angle with adjacent fixture is less than 35 degrees, there will be not be a major problem prosthetically.

Dental Implant Drilling Procedure

Copious saline irrigation is required in the use of any drilling instruments. A surgical splint is used to determine dental implant fixture insertion site. In the maxilla, a fixture for 11 or 21, is placed 3 mm from the midline suture line.

After pilot drilling is done, the fixture site is enlarged using a 3.0 mm diameter twist drill. The procedure is important for preparing the implant fixture site to proper depth. The indicator mark on the drill should be level with the bony margin.
