THE INTERDENTAL ANATOMY: TIPS AND TRICKS FOR CLASS 2 COMPOSITE RESTORATIONS
Marina Papachroni graduated in 1995 from the Dental School of the University of Athens. She completed a three-year post-graduate program and received her Pediatric Dentistry Specialisation Certificate in 1999 and a two-year Master’s Degree in Dental Materials in 2001 from the same University. Thereafter, she has attended numerous Congresses, Courses and Continuing Education Programs. She is the Treasurer of the Board of the Hellenic Academy of Clinical Dentistry and a member of the Hellenic Society of Pediatric Dentistry, European Academy of Pediatric Dentistry and International Association of Pediatric Dentistry. Also she is a member of the Public Relations Committee of the IAPD. Lately, she is lecturing on Bioactive Materials, Dental Trauma, Restorative Pediatric Dentistry and Pulp Therapy of primary and young permanent teeth. The current focus of the clinical research she is involved in, is Painless Anesthesia Techniques in children. From 2019 she is a Lecturer and Clinical Trainer of Intraosseous Anesthesia and a member of the Dentalhitech Academy. She is also a Key Opinion Leader of Polydentia SA in Greece. Dr. Papachroni maintains from 2000, her private practice in Patras, Greece, with emphasis on Aesthetic and Microscopic Pediatric Dentistry.
Interdental anatomy is the most important part of Class 2 direct composites restorations protocol. In vitro and vivo studies showed that the use of a contoured sectional matrix with a separation ring results in the highest contact point.
Interproximal space has a great variety of characteristics; depth, width of the box, distance between the cervical part of the cavity ant the adjacent tooth. After realising the great variation, we can understand the necessity to customise our matrix systems.
In this lecture we will follow an effective protocol with tips and tricks in each step of Class 2 direct composite restorations for primary and young permanent molars in order to obtain a tight, well positioned contact area and an anatomically contoured proximal surface.
Finally we will learn how to “study” the individual characteristics of each interdental space and customise our matrix systems, before applying composite.
