Thanks to referrals of pediatric trauma cases from a pedodontist I work with I have had to get good at quick efficient ways to restore anterior trauma cases in composite. One of the greatest tips is to make a silicone matrix off a wax-up done on a model. I actually have two waxing units, one at home and one at the office. It's fun and it is quick and effective, and it makes me a better dentist as I beef up my dental anatomy skills.
