Technical & Clinical Guide

Selecting the Right Plastic Filling & Restorative Instruments

Achieving natural tooth anatomy, tight interproximal contacts, and void-free restorations requires instruments matched to the viscosity of the restorative material and the cavity preparation geometry. ComDent offers an array of specialized tips:

Instrument Model / Style	Tip Geometry	Primary Clinical Indication
Flat Plastic Instruments	Flat paddle/blade paired with plugger or angled spatula	Carving composite layers, carrying material to preparations, and adapting gingival margins.
Heidemann Spatulas	Ultra-thin, flexible flat blades (straight or angled)	Precise interproximal contouring, shaping anterior aesthetic composites, and stripping flash.
Woodson Instruments	Rounded paddle on one end, cylinder plugger on the other	Placing bases/liners (e.g., calcium hydroxide, GI) and condensing restorative material.
Ball & Acorn Burnishers	Rounded sphere paired with anatomical acorn tip	Blending composite margins, smoothing subgingival borders, and initiating secondary occlusal fissures.
Composite Carvers & Sculptors	Sharp, angled knife/discoidal edges	Refining cusp anatomy, shaping marginal ridges, and carving restorative planes prior to light-curing.

Metallurgy and Surface Finishing

• Ultra-Fine Hand Polishing: The working ends undergo high-grade mechanical and electropolishing to create a microscopically smooth surface. This reduces composite stickiness and prevents black metal transfer on light-shaded aesthetic restorations.

• Optimal Blade Flexibility: Blades are tempered to provide slight elastic flex under pressure, giving clinicians the tactile resistance needed to shape thin marginal edges without bending out of true.

• HTM 01-05 Decontamination Guidelines: Clean immediately after placement using neutral-pH solutions to prevent cured bonding agents or resin residues from setting on the tips. Suitable for ultrasonic baths, thermal washer-disinfectors, and standard vacuum steam autoclaves up to 134°C.
