Applications of controlled local inflammation in aligner treatment

An increase in local inflammation via trans-mucosal osteo-perforations (Propel Excellerating Technology) promotes osteoclastogenesis, osteoclast recruitment and differentiation. This causes the bone to remodel faster and hence teeth move faster through the bone. In combining aligner therapy with controlled localized inflammation, Propel-aided aligner treatment enables clinicians to proactively deliver better outcomes, in shorter treatment times or to reactively respond to resolve and complete stubborn and challenging movements. Experience and evidence of either approach has evolved to make Propel-aided aligner treatment be a valuable, double-edged tool in the clinician's armamentarium. The scope of this paper is to convey such experience and evidence while attempting to suggest techniques for easy clinical adoption and delivery.
