Introduction

Invisalign system has a firm place among techniques of orthodontic tooth movement (OTM). However, very little is known about underlying cellular and biochemical mechanisms.

Purpose

We studied gingival crevicular fluid (GCF) volume as an early sign of inflammatory response to OTM.

Method

Out prospective study had six participants (IRB approval Nr. 14-57). We followed twenty teeth at baseline and at five time points over 14 weeks into treatment with Invisalign. Periopaper strips (Oraflow) were used for GCF collection and Periotron (Oraflow) for volume measurements. Means per groups of teeth were calculated and significance of differences was determined by paired t test.

Results

Major increase of GCF volume occurred at the start of the aligner. Subsequent aligners triggered a diminishing response. A GCF volume measured after two weeks of aligner wear was always lower than the value at the start.

Significance

GCF volume changes, when compared to baseline of the same patient, seemed to follow loading of the teeth with the aligner. The study will be continued with the focus on concentration of cytokines in GCF.
