Fabricating the coping

| The abutment is prepared for either a post and coping (the Preci Post system is recommended), or a cast coping only. Accurate full arch impressions must be sent to the laboratory. Wax up the post-coping as low as possible (FIG 1). Use the 1201P Paralleling Mandrel to incorporate the castable sphere into the wax-up and parallel to each other(FIG 2). The occlusal surface must be at an angle of 90 degrees to the path of insertion (FIG 3). | ||

| Invest, sprue, and cast in the alloy of choice (FIG 4). Do not sandblast the casting when devesting, as this will leave a rough surface on the cast sphere. Use the Cup Bur (FIG 5) to finish the cast sphere. This bur will assure a smooth, spherical shape of the casting. | |
Indirect pick-up of female

| The completed casting is sent out for try-in. The cast coping(s) should be picked up in a new impression and a new master model poured for processing the females. Take an impression with the male in place (FIG 6). The 1201D (FIG 7) analogue will index in the recess created in the impression--exactly where the male is in the mouth. Pour the model (FIG 8). | ||
Processing the Female
Snap the Preci Clix female insert into the metal housing using the Insertion Tool (FIG 9). Place the large tin spacer (FIG 10) over the ball and contour the pliable tin spacer around the ball and gingival area to pre-relieve the acrylic from contacting the cast coping. Be sure to use the big spacer. |

For cases with non-parallel abutments, use the 1211P female mandrel (FIG 11)to set the female housings parallel to each other. A divergence of up to 30° can be accomodated. |
Seat the completed female component over both the ball and both spacers (shown in the mouth and model, FIG 12). Use the 1211 Clix Female Paralleling Mandrel to assure that the females are parallel. |

| Chairside: The prosthesis is relieved to allow room for the female component(FIG 13). Drill a "vent", or small channel in the lingual side of the prosthesis to allow excess acrylic to escape. Low viscous self-cure resin is applied (FIG 14) to pick up the female. |
15 |
16 |
| Chairside: The prosthesis is seated in the mouth for approximately 6 minutes with finger pressure only (FIG 15). Do NOT have the patient bite into place, as this will displace tissue. The self curing or auto polymerizing acrylic resin is pressed into the cavity with a finger covered with vaseline. When the acrylic resin has set, the metal housing is fixed in the prosthesis (FIG 16 ). This allows the female to be easily changed. |

For indirect pickup, process the female component in to the denture base. Remove both the spacers (FIG 17 ). |
