Indirect Restorations Workshop

With the advancement in Materials like Composite, Porcelain, etc.Inlay / Onlay has become a conservative option to Restore large Dental Defects.It not only saves the tooth structure but also is Aesthetic Restoration

• Retention & Resistance form
• Role of Taper & Surface area
• Torque & arc of rotation
• Path of Insertion
• Occlusal Reduction Principles
• Functional Cusp Bevel
• Biological Width
• Two Plane Reduction

Should be followed irrespective of Material chosen for Prosthesis.

• There are 20 golden Rules for Perfect Impression
• Ensure healthy soft tissues.
• Ensure adequate retraction & hemostatic procedure
• Choose appropriate tray & wash material viscositie
• Make sure tray does not show through..

Shade Selection and Lab communications plays an Important role in successful implementation of treatment planned. Waxup plays a very important Role in analysing the tooth Preparation required , as well as Preparing a blue print for the proposed restoration . Waxup also gives an opportunity for patients to view the final result before they embark on the final treatment.

All the steps when followed properly, gives Tooth preparation which is devoid of any undercuts & has well defined margins.

• Driven by Depth Grooves
• Role of Functional Cusp & Bevel
• Safely breaking Proximal Contacts
• 360 degree View
• Finishing of tooth Preparation……

Cervical defects on the teeth can be because of Decay/Erosion. Proper placement of Bevels allows the composite to blend with the tooth in such a way, that it becomes difficult to detect the margins of restoration. For Subgingival/ Equigingival margins it is imperative to Place retraction cord with cord packer gently into the sulcus.

All the steps when followed properly, gives Tooth preparation which is devoid of any undercuts & has well defined margins.

• Two plane Buccal Reduction.

Importance of Coping & Bisque Trial

If attention is paid to fit , margin, path of insertion of copings on the model & prepared teeth , before Porcelain is layered on it, one can save lots of precious clinical time while delivering final Prosthesis.
