For this Part 4 of 4:
Obsidian restorations can be retained with conventional cements, adhesive resin cements or self-adhesive resin cements. In this case, I chose bonded cementation because it increases the overall strength. The etched intaglio surface creates a micromechanical adhesion of cement to the tooth via a silane coupling agent. Resin cement is also very color stable, which makes it especially suitable in the esthetic zone.

The tooth preparation was treated with a 37% phosphoric acid etch gel for approximately 10 seconds, followed by a water rinse for 20 seconds to avoid desiccating the tooth. I then desensitized the tooth with Gluma® (Bayer; Leverkusen, Germany) to seal dentinal tubules and to provide an antimicrobial effect while wetting the tooth to prepare for the adhesive agent. I then used 3MTM ScotchbondTM Universal (3M Corp.; St. Paul, Minnesota) for my adhesive agent.
