Dental preparation in prosthodontics requires precision and adherence to the principles of removing caries and preserving structure. Kexinn's range of restorative drill bits ensures effective removal of tooth enamel with smooth edges

KEY GOALS OF CAVITY PREPARATION

Remove Diseased Tissue: Eliminate infected enamel and dentin to stop caries progression.

Preserve Healthy Structure: Protect intact tooth tissue to maintain strength.

Support Restorative Material: Shape cavities for mechanical and adhesive stability.

Prevent Secondary Caries: Design cavities to reduce food and plaque retention.

Restore Function and Aesthetics: Ensure seamless blending and functionality with natural teeth.

Outline and Decay Removal: Shape cavities to access healthy tissue and remove all caries.

Conservation and Margins: Use minimally invasive methods with smooth, supragingival margins.

Best Burs: Kexinn Round burs for decay removal; pear burs for smooth outlines.

PRINCIPLES OF CAVITY PREPARATION:RESISTANCE AND RETENTION FORM

Structural Integrity: Ensure flat cavity floors, adequate wall thickness, and rounded angles to prevent fractures and withstand chewing forces.

Retention Features: Use grooves, undercuts, or bonding agents to secure restorations and maintain pulpal depth of 1.5-2.0 mm for support.

Best Burs: Kexinn Inverted cone burs for creating retention features, flat floors, and proper pulpal depth.

PRINCIPLES OF CAVITY PREPARATION: CONVENIENCE FORM

Accessibility: Ensure proper visualization and instrument access without excessive cavity enlargement.

Instrument Maneuverability: Use long shank burs to reach deep or challenging areas while preserving healthy tissue.

Best Burs: Kexinn Taper round end, taper flat end, or round burs for precise access and refinement.
