Before lining the aluminum shell with acrylic, close the typodont down tightly over the shell. This will cause indentations on the occlusal surface and will greatly reduce occlusal adjustment after relining.

Lubricate the prepared tooth, adjacent tooth and surrounding gingiva with Vaseline or MQ lubricant.

Mix some acrylic in a dappen dish

Fill the aluminum shell with acrylic. It usually is not necessary to create a hole in the occlusal surface of the shell. Just be sure to seat the crown thoroughly.

When the surface of the acrylic becomes matte, seat the filled shell over the tooth. Press firmly or close the typodont on the crown.

While the acrylic is still soft, remove the excess with an explorer. Don't wait until the acrylic has reached the rubbery stage because excess removal at this point may cause acrylic to be pulled away from the margin area.

When the acrylic has reached the rubbery stage, tease the crown off and on to avoid any chance of locking on.
