AXIS Dynamic Burs Set is composed by a full selecion of Dental burs needed to face all actual situations of the modern dentistery. The main restorative dental activities have been grouped in 5 essentials areas.

Minimally Invasive Procedures

The key to modern Restorative Dentistry resides in preserving the natural capital of the tooth for a maximum amount of time. AXIS’s instruments make possible to tackle pit and fissure sealant, preventive restorations and minimally invasive adhesive cavities accuracy. I have selected four all-purpose burs particularly suitable for this type of dental preparations.

1. Those of you keen on the 330 bur will find an effective substitute for small and narrow cavities at the palatinal aspect of the incisors as well as at the occlusal or proximal surfaces of posterior teeth. FG 1.008

2. A cylinder bur, natural substitute for the carbide pear bur used for amalgam cavities, sealants or preventive restorations. FG 838M.007

3. Its rounded but slightly flat shape allows the access to the distal aspect of the last molars and premolars problemless.
This instrument is perfect for the flat gingival margins of the class V cavities, the weakened cusps or the class II gingival floor. FG 953M.014

4. A fine round bur fulfills perfectly the classic pits and fissures cleaning and remodeling role before the sealant, or as a fissurotomy treatment. FG F 852.010


Due to its physical characteristics and its biological relevance, dentin is probably the most sensitive tooth tissue; preserving it is crucial for pulpar vitality. For this reason, a perfect association of shapes, sizes and cutting power is convenient in order to keep its natural condition.

The access through the enamel was traditionally carried out at high speed while decay was removed with rounded burs at low speed. Nowadays, the use of the multiplicator allows a great enamel cutting capacity, keeping control during the removal of the decay with the same bur. FG Q1.014

Nevertheless the use of a low speed contra-angle may be advisable for the removal of decay or the suitable preparation of the cavity when lack of visibility, nearness to the pulpar chamber as well as weakened cusps are present. CA Q1.018

Accessing the pulpar chamber, post-endodontic preparation or gutta-percha removal often require the use of long shank burs to carry out the task suitably. Class II in periodontal tooth, as well as lesions close to the furcation, can be solved by means of this instrument too. CAL 1S.023

Denta Preparation

Dental preparation comprises the largest part of the usual dental restorative procedures, which can be divided in two big fields:

1. Composite or amalgam cavity preparations for direct restorations. AXIS fissurotomy or rounded diamond burs along with the classic carbide cylinder allow us to perform any cavity design giving flexibility according to the practitioner’s taste. FG 801.012 – FG 855.012 – FG 31R.012

2. Coronal reduction for indirect restorations, from a full coverage crown to a ceramic veneer, including the different on-lays/in-lays. Length and taper options for diamond burs, along with the round or flat end facilitates all types of marginal preparations. Shoulder or chamfer margins will not be a problem anymore. FG G 856.014 – FG G 850.016 FG G 882.012 – FG G 847.018 – FG G 859.012

An intelligent shape, size and cutting efficiency combination facilitates its combined use. With barely six burs, every angle and cutting inclination are perfectly attainable, allowing to make any type of dental preparation. Dental reduction for ceramic veneers, as for in-lays/on-lays, will become banal routine.

AXIS finishing burs bring excellence to the preparations, thanks to the compatible shape and their adapted-to-the-polishing cutting power. FG F 850.018

Restoration Removal

New treatment performance usually requires the removal of pre-existing restorations. Be them crowns, metals or other materials, choosing the right bur speeds up and simplifies the process.

The four most frequent scenarios are: amalgam removal, resin composites, metals or ceramics (indirect restorations).

1. Restoration materials (amalgams, composites, ionomers).
AXIS innovative cutting concept for carbide burs make it possible to penetrate into the restorations with minimum resistance and an excellent cutting efficiency, removing them rapid and easily. FG 31R.012

2. Removing resin cements and old composites from the anterior front requires an exceptional precision in order to maintain health tissues intact, and not alter the anatomy or the aesthetic.

The multi-cutting tungsten burs associated with the multiplicator contribute to control needed to preserve the aesthetic treatment’s results or to finish the orthodontic treatment keeping the enamel and dentin intact. FG 44E.018 – FG 212RL.016

3. Indirect restorations (ceramics, metals or metal-ceramic restorations).

To cut or remove the modern ceramic materials a super coarse grit diamond bur must be used; its cut will ensure rapidity and great abrasion. FG SG 881.016

Metal cutting dental burs will cut the underlying cast metal coping; to avoid clogging with the ceramic material they need a large space. Using a bur with a bigger diameter to cut the ceramic will make the passage of the FG 36R.012 easier removing the metal without resistance while combining it with a contra-angle multiplicator. FG 36R.012

Finishing And Polishing Dental Restoration

The ultimate step towards excellence in dental restoration is high quality finishing and polishing. Trimming the excesses and grosses without damaging the restoration requires dental burs whose forms and abrasion capacity allow for precise control throughout the process.

The contouring of the concave areas benefits from round or ovoid burs that preserve the existing surface.
FG F 801.018 – FG F 368.023 – FG 44E.018

Access to the proximal areas or to the most winding occlusal surfaces require the use of the finest fissurotomy burs for grooves or pits, and concave burs to respect the convex surfaces of cups and cuspides. FG F 852.010 – FG F 833.031
The flat or slightly convex surfaces of the anterior teeth and the proximal profiles are trimmed and polished suitably with the longest inverted taper burs. Their large diameters and their rounded ends impede them from getting stuck and from creating accidental grooves and scratches, as well as make them more respectful with the surrounding soft tissues. FG 212RL.016 – FG F 850.018

To ensure an optimal aesthetic result and to extend the longevity of the restoration, bevel preparation and the demarcation of the cavitary margins and prosthetic reduction are fundamental. This bur selection allows for a perfect performance of these tasks, with no need of further instruments. FG 212RL.016 – FG F 850.018

Prof. Alfonso ARELLANO

Elaborated in narrow collaboration with the professor A. Arellano, international speaker and Bilbao’s Dental University regular teacher, AXIS dynamic burs set answers the great majority of the situations.

The main restorative dental activities have been grouped in 5 essentials areas. For each of them, the professor A. Arellano carefully selected the best products and set up a working system combining simplicity with versatility.

The multi-task concept aims at reducing the number of instruments on hand and answering daily needs as well as specific demands. The selected shapes and sizes allow the practitioner to operate with the essential tungsten carbide and diamond burs. Used with a multiplicator, precision and comfort are largely improved. Thanks to a choice of instruments selected by a professional, for professionals, AXIS dynamic burs set allows a comfortable procedure without sacrificing the goal of excellence.
