INDIRECT Burs Kit

Initial situation

Patient with two metal-ceramic central crowns after trauma. Endodontic retreatment, crown replacement, vertical preparation, bleaching, and feldspathic veneers from 15 to 22 restored aesthetics and masked root discoloration.

Preparation

Technique removes tooth emergence profile and old finish line, creating a new area where crown margins can be shifted coronally or apically according to provisional restoration design.

i1 Depth Marker

First bur define veneer thickness. Based on wax-up volume and tissue preservation, burs are chosen. Pencil marks on initial grooves ensure precise preparation depth control for accurate results.

Final result

Final result: BOPT, simpler and faster than chamfer or shoulder. Proper temporary crown fabrication, with relining and profile shaping, ensures the desired form and fit of the final restoration.

i1 for 0.5mm depth marker bur

i2 for 1 mm incisal and buccal reduction

i3 for reparation and surface smoothing

i7 for proximal opening, feather-edge

i8 for Palatal reduction

A large football diamond bur for fast palatal reduction and space creation.

i6 or i2 for Axial and incisal reduction

i6 for fast axial reduction without creating margins or for feather edge margin, use i2 in case a light chamfer is needed.

i7 or i3 for fine preparation

Smoothen full prep and finish feather edge. Use i3 for light chamfer if needed.

Initial situation

The initial situation involved a patient presenting with an old amalgam restoration on the lower first molar, which exhibited signs of infiltration.

Onlay

Once completed, preparation for the indirect restoration (onlay) was carried out using the STYLE INDIRETTO burs kit.

Overlay Conditioning

Overlay conditioned before cementation: 9% HF acid, rinse, 37% phosphoric acid, rinse, then silane application and air-dry.

Final result

Step luting protocol simplifies excess cement removal, especially interdentally, while universal adhesive and resin cement ensure long-term success.
