Case Study By Dr. Enrico Cogo, Italy 3D rings are the real topic of Garrison’s sys- tems. The “v” shape of a ring that fits in the interproximal area allows a good fit between the cavity margins and the matrix in the buc- cal and palatal walls. This results in easier po- sitioning of the composite masses close to the cavity margins, and final remodeling (usually necessary at the time of removal of the matrix) will be very minimal. The rings also permit a divergence of the in- terproximal dental elements, which causes a great point of contact. Garrison systems make second class restora- tions more simple and more predictable and also reduce the operating time of the finishes when the matrix is taken off. Dr Enrico Cogo DDS Dr. Cogo graduated from the Uni- versity of Ferrara, Italy with a degree in Dentistry in 2005. Since 2006, he has been a visiting professor at the Dental School of the University of Ferrara. Dr. Cogo is also a frequent speaker at courses and conferences on dental bleach- ing and esthetics, as well as direct and indirect adhe- sive restorations. He is the author of several scientifi c articles in national and international journals, and with his associates, Pietro Sibilla and Roberto Turrini, wrote the book “Sbiancamento dentale: metodi per il successo,” edited by Quintessenza Edizioni and trans- lated into German. Dr Cogo also has private practices in Legnago (Verona), Ferrara, Goito (Mantova) and San Giuseppe (Ferrara). Pre-op situation. Patient needs to replace an old amal- gam restoration on 1.5. Dental elements are isolated with rubber dam to avoid contamination of the area and improve visibility. Picture of the cavity after removing the amalgam res- toration and after performing the cleaning of cavity. After finishing of the cavity, a sectional matrix Compo- si-Tight 4.6 mm, a wooden wedge and 3D XR ring are placed. The ring is placed on the wedge and causes a slight divergence which will result in an excellent point of contact at the end of the restoration. Situation after removing ring, matrix and wedge. Good position the matrix and the use of an adequate ring allows minimum interproximal finishing at the end of the stratification. Post-op view after polishing and check occlusion. A good contact area is performed between elements 1.5 and 1.6.
