The Use of Dental Sandblasters in the Orthodontic Practice

Dental sandblasters that are used in dental laboratories are enclosed and often operate through a vacuum or via air compressor. Dental laboratory sandblasters are operated via foot pedal and often feature gloves to work through, this keeps everything contained. Sandblasting media can be Aluminum Oxide, glass beads or Silicone Carbide grit. Be sure to choose a dental laboratory sandblaster that employs proper dust retraction.

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.

Dental sandblasters can also be intraoral and used in dental operatories. Also referred to as air abrasion, dental sandblasters can be used instead of dental drills in various procedures. Intraoral dental sandblasters have a variety of angled tips allowing the technician to reach any part of the mouth.

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( dental amalgamator ), 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.

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.
