Sandblasting In The Orthodontic Practice

Date - 02/11/2010

Dental Sandblasters The Deldent Miniblaster TM is being recognized as an indispensable Chairside Dental Tool in the orthodontic practice. Among its applications are the following:



Not uncommonly, an orthodontic bracket may be dislodged from the tooth during orthodontic treatment. If this occurs, the choice is either to replace it with a new bracket (additional cost of bracket) or if available, to recycle the bracket by means of a recycling technique.


Sandblasting of the mesh of the bracket will completely remove old existing composite and will enable the same bracket with a superior sandblasted surface to be rebounded in the same patients mouth immediately. The total procedure takes only a few moments and a few cases will quickly cover the cost of unit, in time and convenience, as well as a saving in cost of additional brackets.



Molar bands may come loose during treatment. In most cases, it is the bond between the adhesive cement and the band that has failed, the adhesive to tooth junction often remaining intact. Prior sandblasting of the inner surface of the bands, especially in critical situations, such as with a rapid palatal expansion appliance, can significantly reduce this occurrence.


Bands that come loose should be sandblasted. This will remove old cement and prepare the band surface for re-cementation.



Simple retainers (e.g. lingual cuspid to cuspid retainers) can be fabricated and bonded to the teeth, after sandblasting the bonding areas of the adapted wire (Zachrisson JCO 1995)


Bonding in the adult patient

Bonding can be more difficult in the adult patient where a great variety of restorations may be encountered, that cannot be bonded to, with routine bonding protocols, as is the case when bonding to the natural teeth. These include crown and bridgework and restorations of various materials; amalgam, composite, porcelain and precious metals.


Effective bonding to artificial surfaces has been facilitated by new techniques and materials but mechanical retention is an importantally to all bonding techniques.


Roughening a surface with burs or stones may create the appearance of roughness due to the periodic grooves and ridges but little micro-mechanical retention is achieved. (EDelA.and Edel J. Ind Dent.1998)


The Deldent Miniblaster strips away contaminants and a microscopic layer of metal, composite or porcelain depending on the material being blasted, creating a retentive surface with a miryad of microscopic undercuts. This increased surface roughness significantly enhances bond strength.


The Deldent Miniblaster - Sandblaster has been approved by the FDA for intra-oral use to enhance bonding and its additional clinical applications are only limited by the imagination of the operators.


The DUST INN 2000TM Compact Esthetic Dust Collector is an excellent companion to the Miniblaster. It is designed for use with all Miniblasters or Microetchers and for chairside grinding procedures.


It has excellent all round visibility and features an efficient 12 volt filtered extraction system that is quiet, and by creating a negative pressure that efficiently contains the abrasive particles in the unit and not in the operatory.


No need to trip down the hall to the lab. Now, everything is conveniently available just a half  turn away, thanks to this esthetic and practical device which is nice enough to let your patients see. This is especially beneficial when treating anxious youngsters, and allows you to maintain the uninterrupted patient/doctor exchange that is so important.


The Dust-Inn is a high-style contemporary unit that not only fits well into the clean, sleek design of modern dental décor, but eliminates the need for accessory lighting, due to the transparent dome that provides all-round visibility. Best of all the Dust-Inn is scaled to fit on an operatory countertop without getting in the way.
