Anterior Direct Restorations  The purpose of restorative dentistry is to lose tissue due to caries, trauma, etc. physiological and aesthetic properties of teeth and It is the restoration of its anatomical structure. Treatment in restorative dentistry Alternatives have increased with the development of adhesive dentistry. Lesions in the dental tissue are treated conservatively.  Restorations for aesthetic purposes Direct composite restorations Indirect composite & porcelain veneers All-ceramic crowns  Thanks to advances in adhesive technology and composite resins,  without the need for any form of preparation or some tissue Closing the gaps by applying the composite resin to the tooth surface by removing it,  It has become possible to reshape the teeth.  Caries & Trauma & Tissue loss due to collateral lesions without caries Diastema Deformities Tooth discoloration The Purpose of Minimally Invasive Treatment in Aesthetic Dentistry To be able to protect dental tissue Maintaining gum health Achieving successful results in a short time What does a good restoration depend on? 1- Physician 2- To the method of treatment 3- Material 4- Patient Aesthetic principles in the anterior region Macro Micro  Macro Mini In the resting - Midline position: - Facial triad Komissura level Inter-papillae Filtrum height plane Naso-labial angle Visibility of the upper cutters In the laughing position: Laugh line Dental midline Smile symmetry Buccal corridor Appearing in the laughing field mouth area Lip line  Micro - Proportion of upper power plants - Golden ratio - Incisal embryos - Location of contact points - Color gradient - Surface microstructure - Gum shape - Gingival contour - Gingival embryo - Zenith points - Gingival level  Direct Aesthetic Restorative Materials Composi Glass Resin Kompomer Giomer te resin ionomer modified glass ionomer Material losses in dental tissues A wide variety of restorations are carried out to eliminate it. In the construction of these restorations, different materials are selected for the region and purpose.  Factors influencing the choice of restorative material The characteristic structure of the tooth itself Factors of the material to be used (resistance of the material, wear, residence time in the mouth, technical sensitivity) Dentist factors (skill, experience) Patient's factors (expectation, oral hygiene, habits, extent of restoration applied, socioeconomic level)  Factors related to the characteristic structure of the tooth The amount of substance loss in the tooth Support of dental tissues Localization of the tooth Discoloration of the teeth Dental anomalies  Composite resins have physical and mechanical properties very close to natural tooth tissue today. Due to these materials, we can give a natural dentin and enamel-like appearance on tooth surfaces. 1- colour 2- isolation Selection 3- Preparation 7- Treatment 4- preserva Finishi protocol tion of ng and pulp polishi ng 6- material Application of restorative  5- Aci d- bondi ng  Color selection Before the preparation Under proper light Dentin from slave (Middle triplet is an important criterion) Incisalden enamel  isolation Rubber-dam Teflon tape Cotton bumper Retractor  Preparation Removal of decayed tissue Bizotage preservat ion of pulp calcium hydroxide (Dycal etc.) mineral trioxide aggregate (MTA) resin based calcium silicate (TheraCal) Tricalcium silicate (Biodentine)  For retention, 0.5 mm enamel bevelage is applied.

This cavity shape is most preferred in class III, IV or V restorations.  If there is any defect or bruise, it is included in the cavity. The size of the old or faulty restoration determines the outer boundary of the cavity. The enamel prisms exposed by the biblotage process are roughened more effectively with acid. Acid on the byodated surface, enamel It acts at the maximum rate at the appropriate angle to its prisms. The only difference from the traditional preparation is that the cavity edges limited by enamel are beveled and the composite resin After moving a little to the beveled enamel surface, it is reset is to be finished. Conservatism is basically micro- It is provided by mechanical adhesion, so the tooth structures are preserved.  After some composite is carried to the surface of the composite tooth is finished.  Advantages of the byotage process  The roughened enamel area expands.  By removing the fluorine-rich outer layer of the enamel, the prism tips are exposed and a more effective roughening is made.  The retention of resin increases.  Since there is no need for retention grooves, substance loss is low and A more conservative preparation is prepared.  Edge leakage and secondary caries and discoloration are significantly reduced.  Since the resin is carried to the surface of the beveled enamel, the enamel with resin The line image formed as a result of the end-to-end combination disappears. Surfaces on which the bioraging process cannot be performed:  Due to the lack of little or no enamel and also due to transportation difficulties, it should not be applied to the gingival edges in the aproximal areas.  Thin composite edges of the cavity edges, which coincide with areas of centric contact points and intense chewing forces on palatinal surfaces It should not be done as it may break. Application of restorative materials  Layering Method Method one: After obliquely applying one or two layers of dentin-like composite layer, an enamel-like layer that completely covers the surface is applied. This method is used in class 3 and small class 4 cavities and small shape arrangements.  Second method: It is the technique used in simple cases with a hand-prepared mock-up or in advanced cases with a silicone key (index / matrix) prepared from wax-up.  The first layer, enamel composite, is applied directly on the silicone key.  Single at once Restoration Palatinate (linguali) and Incisal Edge is created.  Dentin composite and effect materials can then be placed in three dimensions.  This method provides suitable conditions for the most suitable aesthetic result, in which we can create natural traslucensi, opacity, halo effect.  Enamel colors  A1, A2, A3.., B1, B2,..  A1E,..., B1E,,,  Light enamel, dark enamel  E1,E2,E3  Incisal edge colors  Translucency  OBN  Ambergris  Clear  Blue  Gray  Dentin colors  A1, A2, A3.., B1, B2,..  A1D,..., B1D,...  Light dentin, medium dentin, dark dentin  D1, D2,.....  UD0,UD1,UD2,....
