I already have a video on rubber dam placement on my channel. My team is working on producing more clinical videos for the future, including endodontic access openings!
Class II preparations are notoriously challenging! Both the preparation and restoration can be difficult, but I promise that it gets easier with practice and experience. Also I have found over the years that some patients have tighter contacts or wider contact areas that can be especially challenging to prepare and restore so it varies from patient to patient.
Beautiful! I would like to ask if it is correct to start reconstruction with the matrix retainer and then put a base and next retention grooves and finally amalgam? To avoid excessive bleeding on base material when putting matrix retainer on?
If the preparation comes within 0.5mm of pulp tissue a cavity liner is recommended for thermal and electrical insulation. If 0.5-2mm away from pulp, a base is sufficient. If 2 or more mm away, then a desensitizer like GLUMA will suffice.
The only reason why dentists don't use these anymore is because most US dentists are all about efficiency. They would rather use composite fillings than amalgam as it's faster to implement vs amalgam. Though, amalgam fillings are lot more durable. Still, amalgam placement are still taught in dental school.
