Fig. 12-62. The cast cobalt-chrome implants are seen on the model. Two small cobalt-chrome set screws are some-times used for securing the implants to the bone. They are screwed through the two openings seen on the distobuccal aspects of the implants.

Fig. 12-63. A, The implant is ready to be placed over the exposed bone. B, Both implants are seen fitting accurately to the bone.

Fig. 12-64. The tissues are closely adapted to close the wounds and to closely cover the necks of the implants.

Fig. 12-65. A temporary acrylic splint is sometimes fabricated if the fixed partial denture is not fabricated prior to the implant insertions.
