The cone socket pliers (26) are used to bend the bladevent until its curve (27) matches that of the socket (28).

Caution: A bladevent must fit its socket passively along the socket's entire length. Forcing a bladevent into strongly resistant bone will spread the socket walls beyond the bone's physiologic capacity, destroying bone cells and widening the socket.

The correctly bent blade is inserted into the socket along the socket's axis (29) . Anteriorly, this is relatively easy to do by hand. Posteriorly, a special carrying instrument is often necessary (29A) . Manual pressure should be adequate to lodge the implant. If the implant slides in easily up to the bottom of its post, the socket is too wide. If the bladevent cannot be made tight in its socket by bending its body into an s-curve, the site must be abandoned.

The angle of bending is estimated, and the bladevent is with-drawn by hand (30) or with an implant remover (30A) Crown Socket Remover.

Caution: The implant never should be rocked (31) out of its socket!

Two cone socket pliers are used to bend the neck of the post (32) gradually to the proper angle. The post should not be worked back and forth innumerable times, trying for a good angle. Frequent bending will weaken even the strongest metal.

Caution: To bend the neck of the post, grasp the body of the blade-vent perpendicular to its length where the neck meets the shoulder (33). Do not grasp the entire length of a curved blade (34) with the pliers. Such a grip would flatten the carefully created, accurate curvature.

Caution: The bladevent's neck should not be bent in the mouth with the bony walls of the socket used as a vise. This would crush living bone cells and possibly fracture the walls.

When all abutments are satisfactorily angled, the individual bladevents are ready for final seating.

The socket is cleaned of debris with water and a special channel
guide (35). This instrument is designed to help detect unevenly
deep, improperly prepared sockets. If the tool pops up while passing
it along the base of the socket, an obstruction (36) is indicated.
This must be removed with the 700 XL bur to seat the blade evenly.
The sterilized implant is replaced. It must now be seated to its
