DYNAMICS • Development of High speed handpiece along with acknowledged benefits of water coolants- led to the concept of four-handed dentistry. • Conservative restorative bonding techniques. • Increasing professional emphasis on carious prevention is as important as the recent technologic and scientific advancements. • Vastly improved Dental materials. Dentistry Explorer

Dynamics • All of the factors mentioned above have played an important role in the development of Operative Dentistry. • They have resulted in the reduction of the incidence of caries and a more conservative and effective approach towards treatment. Dentistry Explorer

Procedures commonly done are ØDirect Restoration- Amalgam, Composite resin, GIC. ØIndirect Restoration- Inlay, Onlay, Crowns (base metal, precious metal, porcelain fused to metal, or metal free ceramic) ØVeneers- Direct or Indirect Dentistry Explorer

Direct Restoration v. After tooth preparation, the restoration is placed in a moldable stage in the prepared tooth to recreate normal contours. Advantages: Easy to place, less time consumed, and cost effective. Disadvantages: Compromised mechanical properties Dentistry Explorer

Indirect Restoration • After tooth preparation, it involves making of impression, pouring of cast, die preparation, wax pattern, investing, casting, finishing, polishing and cementing (or luting) of restoration. • Restoration is fabricated outside and cemented to prepared tooth. Dentistry Explorer

Indirect Restoration • Advantages: provide better mechanical properties and stress distribution. • Disadvantages: time consuming, expensive, and more technique sensitive. Dentistry Explorer

Dentistry Explorer

New Concept • Tooth preparation originally adhered to the concept of ‘extension for prevention’, but increased knowledge of preventive methods, advanced clinical techniques, and improved materials now have provided a more conservative approach to the restoration. Dentistry Explorer

Pre Clinical Operative Dentistry • Is a branch of Operative Dentistry wherein practical training is given in cavity preparation and restoration of teeth with various materials in dummy models in simulated oral environment. Dentistry Explorer
