1. Posterior composite restorations; tools, materials and techniques. Dr:Mena Rafat

2. Outline: Introuduction Indication & contraindication of posterior composites restoration Tools Materials techniques

3. introuduction Post composite is used to restore posterior teeth in different classes: I,II, V, VI

4. Indications Class-I, II, III, IV, V & VI restorations. core buildups. Sealant & Preventive resin restorations. Esthetic enhancement procedures. Periodontal splinting.

5. contraindications In patients with high caries risk and poor oral hygiene. High occlussal stresses as in patients with para-functional habits like clenching and bruxism. Patient allergic & sensitive to resin composite. Subgingival difficulties .

6. Tools

7. Posterior misura Measuring thickness of composite layers condensa Condensation to prevent voids Eccesso Excess residual removal Applica twist Proximal walls and marginal ridges Easier approach to inaccessible areas 7

8. Cusp misura Measuring cusp thickness and height Solo posterior Composite modeling Replica posterior Cusp modeling fissura Occlusal anatomy 8

9. Wedges Wooden wedge A+ wedge Coated with aluminium sulphate 3D fusion ultra adaptive wedge Diamond wedge

10. 1)sectional matrix: achieve a strong contact point in Class II restorations with composite resin in the posterior 2) saddle matrix: it is useful for teeth without an adjacent tooth or distal caries on a last standing tooth. 3) compensating for the missing walls of the tooth and containing the filling material, and can be easily manipulated to match the natural contours of the treated tooth
