Crown Preparation Kit
An excellent marginal fit is key to restoration longevity and success. Excellent fit requires good marginal preparation. Restorations fail at the margins more than anywhere else, leading to adhesive failure of the bond or cement wash-out, leakage and pulp symptoms. This kit provides a comprehensive selection of burs that are needed for crown preparations.

Kit of 14 burs:
G828-314-022:
The 0.3mm depth cutting bur is used to make surface depth grooves to guide accurate tooth reduction during preparation for minimal thickness ceramic veneers.
G828-314-026:
828-026 is a 0.5mm depth cutting bur used to make surface depth grooves to guide accurate tooth reduction during preparation for veneers and crowns.
G828-314-030:
This 0.7mm depth cutting bur is used to make surface depth grooves to guide accurate tooth reduction during preparation for deep ceramic veneers and crowns.
G850-314-014:
This bur has a tip diameter of approx. 0.9 &ndash1.0mm. So placing the tip to one third of its depth provides a suitable narrow chamfer for metal margins. The taper is suitable for crown and veneer preparation.

G839-314-014:
The end cutting bur with safe sides for marginal finishing is used to remove any enamel rim which is often created by the use of round ended crown preparation burs
G379-314-023:
This egg shaped bur is designed for palatal and occlusal contouring during tooth preparation for crowns and bridges.
G379-314-023:
This bur is designed for finishing palatal and occlusal contours, and tooth preparation for minimally invasive resin-bonded bridges. It can also be useful for finishing composite restorations on occlusal and palatal surfaces.
G860-314-014:
The fine flame is used for finishing all surface contours and can also be useful for finishing composite restorations.
