4. INTRODUCTION
• The damaged teeth are to be restored in their form and
function so as to achieve conducive stomatognathic
environment.
• The operator may get confronted with situations where
direct restorations are not feasible and advisable because
of existing conditions
• Many a times, certain conditions warrant preparation of
the restoration outside the oral cavity. Such restorations
are known as ‘Indirect Restorations’

5. TREATMENT PLANNING
Product B

6. PRINCIPLES OF TOOTH PREPARATION
 Permissible occlusal convergence
 Height of axial walls (incisal/occlusal-cervical length)
 Geometric form of the prepared tooth (surface area)
 Depth of reduction
 Location and form of finish lines
 Auxiliary retentive features
 Assessing final form of the preparation
 Confirm uniformity of preparation before impression making

10. INLAYS AND ONLAYS

11. ONLAY
• The inlay, being an intracoronal restoration, may not protect the remaining weak tooth structure, if any.
• Such restorations, depending upon their buccolingual width, usually exert a wedging pressure outward from the
center of the tooth. If more than one-third of cuspal incline planes are involved, the concerned cusp(s) should be
covered.
• The onlays protect the remaining weaker tooth structure from occlusal, laterally and apically directed forces.
 Cusp reduction- tapered fissure bur
 1mm- buccal/lingual
 1.5mm- occlusal
 Chamfer- gold
 Shoulder- cast metal

18. LAMINATES
 Laminate is defined as a thin slice of acrylic/composite/porcelain fabricated in
laboratory and cemented onto the teeth.
 A veneer is a layer of tooth colored material that is applied to a tooth to restore localized
or generalized defects and intrinsic discolorations.
 The laminate veneer is a conservative esthetic restoration of anterior teeth to mask
discoloration, restore malformed teeth, close diastemas and correct minor tooth
alignment. Laminate is bonded directly to the prepared tooth.

20. COMPONEERS
Componeers are prefabricated composite veneers, especially manufactured in thin shells
that can be fixed onto the labial surfaces of teeth.

21. LUMINEERS
ADVANTAGES
• Fast and painless technique
• Tissue management not required
• No postoperative sensitivity and pulpal
involvement
• Long-lasting Esthetically pleasing (patient
acceptability)
• No need for provisional restorations
• Can be placed over unesthetic crown without
replacing the same
• In case patient dislikes, it can be removed and
the surface is polished to achieve the same
tooth.
DISADVANTAGES
• May appear bulky and Over contouring
• may harm periodontal tissues
• The width and length may not be altered
significantly
• Color masking is not proper
ultrathin porcelain veneers - bonded directly over the tooth structure to enhance esthetics.

25. FAILURES OF INDIRECT RESTORATIONS
1. Discomfort
2. Loose Restoration
3. Recurrence of Caries
4. Loss of Supporting Structures
5. Degeneration of the Pulp
6. Fracture of Restoration and/or Tooth
7. Loss of Functions
8. Loss of Esthetics

26. CONCLUSION
Dentistry has benefited from tremendous advances in technology with the introduction
of new techniques and materials. The combination of materials and techniques are now
beginning to emerge which aim to exploit the best features of each.
There is still considerable space for the improvement of properties and microstructures
of materials including a more critical attempt to mimic the structure developed by
nature. The search for the ideal restorative material continues…..
