2. Restorative and esthetic dentistry is the treatment of the general
dental needs of a patient.
Introduction
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. 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. 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. 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. 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
10. A class II lesion is an extension of theA class II lesion is an extension of the
class I lesion into the proximalclass I lesion into the proximal
surfaces of premolars and molars.surfaces of premolars and molars.
•Areas for class II decay involve:
A. 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. 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. 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. 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. 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.
