  2. 2. Restorative and esthetic dentistry is the treatment of the general dental needs of a patient. Introduction
  3. 3. Restorative Dentistry  Specific conditions that initiate a need for restorative dentistry are: • Initial or recurring decay, replacement of failed restorations, Erosion , abrasion or the wearing away of tooth structure.
  4. 4. Esthetic Dentistry  Specific conditions that initiate a need for esthetic treatment are: • Discoloration due to extrinsic or intrinsic staining, anomalies due to developmental disturbances, abnormal spacing between teeth, trauma.

  7. 7. Patient Preparation for Restorative Procedures Inform the patient of the procedure to be performed and what to expect during the treatment. Position the patient correctly for the dentist & the type of procedure. Explain each step as the procedure progresses.
  8. 8. Components of a Restorative Procedure Dentist evaluates the tooth to be restored. Dentist obtains local anesthesia. Assistant readies the type of moisture control to be used during procedure. Dentist prepares the tooth for the restoration. Dentist determines the type of dental materials to be used. Assistant mixes and transfers the dental materials. Dentist burnishes, carves, or finishes the dental material. Dentist checks the occlusion of the restoration. Dentist finishes and polishes the restoration
  9. 9. Surfaces involved are:Surfaces involved are:  A class I lesion affects the pit and fissures of the teeth. A. Occlusal surfaces of premolars and molars. B. Occlusal two thirds of the facial surfaces of mandibular molars. C. Occlusal third of the lingual surfaces of the maxillary molars. D. Lingual surfaces of maxillary incisors, most frequently in the pit near the cingulum. Class I Restorations

Two-surface restoration of a posterior tooth. B. Three-surface restoration of a posterior tooth. C. Four- or more surface restoration of a posterior tooth. Class II Restorations
  11. 11. Class III and IV Restorations  A class III lesion affects the interproximal surface of incisors and canines. A class IV lesion involves a larger surface area, which includes the incisal edge and the interproximal surface of incisors and canines.
  12. 12.  The gingival third of the facial or lingual surfaces of any tooth.  The root of a tooth, near the cementoenamel junction.  A class V restoration is classified as a smooth surface restoration. These decayed lesions occur at: Class V Restorations
  13. 13. Complex Restorations  Retentive Pins • Placed when decay has extended into the cusp of a tooth and undermined the enamel and dentin. • The general understanding when using retention pins is that one pin is placed for each missing cusp.
  14. 14. Direct Bonded Veneers  A veneer is a thin layer of tooth colored material applied to the‑ facial surface of a prepared tooth.  A veneer is used to improve the appearance of teeth that are: • Abraded, Eroded, Discolored with intrinsic stains & Darkened after endodontic treatment.
