crowns or bridges or dental dental implants. The materials vary, but the technique is even more important. The eggshell technique can help create ideal soft tissue outcomes.

• A prefabricated shell can be created and then relined.
• Hard tissue stops are 100% necessary, so if there are none, this is a great way to do it.
• This method works really well for full arch cases (that can include bridges) as well as posterior sextants on the mandible.
• Bisacryl can be used to make a shell, and then hollow it out.
• If this method is used, the shell created by the bisacryl needs to be trimmed in 2 different methods.
• The shell can be about 0.5mm thick.
• This provisional can also be done by a lab using milling.
• When using bisacryl, one coat of bonding agent needs to be placed and cured, then a second layer needs to be placed, but not cured, then the temp needs to be relined.
• Flowable composite at the margins are great for lab made temps.
