ABSTRACT

Debonding with new materials and new techniques: command-debond and methods to minimize grinding of adhesives

The lecture presents the fundamentals of the bonding interfaces and the phenomena occurring during debonding a result of which is the production of aerosol. It also analyzes the effect of the constituent components of the bracket bonding complex on the production of aerosol whilst it presents an overview of the currently available materials and methods to limit the generation of particles resulting from the use of rotary instruments. These include the use of heat or freezing probes to impose a viscous or brittle phase of the composite; the use of iron fillers with the application of magnets to induce the structural breakdown of the adhesive; irradiating the composite to reverse its phase from the crystalline structure back to the viscous state; and the development of adhesives with thermally expandable fillers which can induce crack propagation from inside out. Guidelines for the avoidance of aerosol contamination of the operatory and the potential microbiological, endocrine disruptive and respiratory effects of aerosol are also provided.
