We obtained very good results using the 3D-software to adjust the oc- clusion of posterior crowns with the aid of the centric bite regis- tration function and the auto- matic adaptation of the crowns’ occlusion with the antagonists. When required, manual correc- tions can, be made by the user at any time. Figures 5 a and 5b show the crown in the milling preview after completion of the design. According to the results obtained in situ (shade of pre- pared tooth 4L2,5 / tooth shade 3M2), a block in the shade 3M2 was chosen for the manufacture of the crown. The VITA ENAMIC Polishing Set clinical and the VITA ENAMIC STAINS KIT are available for reworking chairside manufac- tured VITA ENAMIC restora- tions. The polishing set includes a total of eight polishers for the handpiece, four for prepolishing and four for high-glaze polish- ing. A staining set is also availa- ble. Beside six stains, this also in- cludes VITA ENAMIC Glaze for sealing the surface. The stains and the glaze are light-curing and very easy to process. The de- finitive intraoral cementation of the marginally accurate crown (Figs. 6 and 7)was performed with Multilink Automix (Ivoclar Vivadent), since VITA ENAMIC has a high loading capacity after adhesive bonding with the re- sidual natural dentition. Material benefits Experience shows that the new VITA ENAMIC blocks can be milled very quickly from the dig- ital design. This ensures milling results with high precision, edge > Page 29 Cleanic® A universal prophy paste with Perlite technology Cleanic: Clinical use of a recognised prophy paste with Perlite ByDr.FabioCosimi D.D.S. Dr.SusannaGiovannini D.I. I-OstiaLido,Rome C leanic® prophy paste by Kerr has a creamy and smooth consistency. It also has a pleasant fresh taste that is not too strong and is well accepted by the patient. This creaminess and the clever use of binding agents have made the paste easy to use. Available in a tube, used with both cups and brushes, the paste stays more compact on the tooth surface, thereby avoiding the unpleasant sensa- tion caused by coarse particles left in the patient’s mouth. Within a few seconds after ap- plication (during the cleaning cycle), Cleanic® paste removes extrinsic dischromia caused by chlorexidine or stains caused by cigarette smoke. (If either of these are present in a patient at a recall of 6 months, the application should be re- peated). About 8 seconds after appli- cation, the paste automati- cally starts its polishing action thanks to Perlite technology making the tooth appear smooth and shiny. After our usual professional oral hygiene procedures (de- bridement, scaling and root- planing), Cleanic® paste, compared with others on the market, seems to be less appar- ent in the gingival sulcus. Pro-BrushTM new genera- tion brushes are very suitable for patients with dental over- crowding or malpositioned teeth. Plastic replaces the tradi- tional metal part and allows the brush to rotate more efficiently. This helps to prevent damage to adjacent teeth. Pro-Cup® cups have been de- signed and developed to avoid pastes being splattered as with traditional cups. Before Procedure After
