Operative Dentistry is the art and science of  the ____, _____ and ____ of the defects  of teeth that do not require full coverage restorations

for correction.

Modern Operative Dentistry

includes diagnosis & treatment of many problems not just caries.

diagnosis & treatment

Modern operative dentistry includes _____ and ___ of many  problems not just  caries.

Modern operative dentistry

Terms “Tooth preparation” & “restoration”

Terms “Tooth preparation” & “restoration”

Modern operative dentistry terms are:

• diagnosis

• prevention

• interception

• preservation

• restoration

PURPOSE OF OPERATIVE DENTISTRY

diagnosis

Proper diagnosis is vital for treatment  planning.

prevention

To prevent any recurrence of the  causative disease and their defect.

interception

Preventing further loss of tooth structure  by stabilizing an active disease process.

prevention

Preservation of the vitality and  periodontal support of remaining tooth  structure.

restoration

Includes restoring form, function,  phonetics, andesthetics.

•Caries

•Malformed, discolored, nonesthetic or  fractured teeth &

•Restoration, replacement or repair.

INDICATIONS

•Infection control.

•Thorough examination of oral and systemic health of  patient.

•A diagnosis of dental problem that recognizes  interaction of affected area with other body tissues.

•A treatment plan that has the potential to return the  affected area to a state of health and function,  enhancing the overall health and well-being of the  patient.

•An understanding of the material to be used to  restore the affected area,including a realization of  the material’s limitations and techniques involved  in using it.

•An understanding of the oral environment into  which the restoration will be placed.

•An appreciation for and knowledge of correct  dentalanatomy.

•An understanding of the effect of the operative  procedure on other dental treatments.

Considerations

“extension for prevention.”

Conservative Approach

 Earlier concept of ______

Increased knowledge of prevention methods

advanced clinical techniques

improved restorative materials

_______, _______ and ______ have provided a more conservative approach to the restoration of teeth.

(1) many typical restorative procedures (Classes I, II, III, IV, and V)

(2) diastema closure procedures

(3) esthetic or functional correction of malformed,  discolored, or fractured teeth; and

(4) actual replacement of teeth

More conservative approaches are available for

primary results of conservative treatment

The primary results of conservative treatment are retention of more intact tooth structure and less trauma tothe  pulp tissue and contiguous soft tissue.

high-speed hand piece

The development of the _______ played a dramatic role in the more conservative and efficient removal of tooth structure for restorative procedures

Mechanical bonding

______ by etching enamel and dentin and use of bonding systems have led to the  development of many new composite restorative materials and conservative restorative bonding  techniques.

pit-and-fissure caries.

 Benefits of sealants are becoming more widely accepted for the prevention of _____

caries incidence

Increased knowledge about the carious process and the beneficial effects of multiple fluoride applications has resulted in a decrease in ____

biomaterials

Increased research on biomaterials has led to the introduction of vastly improved dentalmaterials.

lasers

Use of ____ in dentistry may lead to a new  mechanism for welding dental alloys or altering tooth structure in tooth preparation.

composites, adhesive systems, castable ceramics, and computer- generated restorations

Improvements in ____ could result in significant decrease in the use of metal alloy systems in operative dentistry

anti-caries vaccine.

Efforts also are being made to develop an ____
