The impact of the primary canine premature extraction on the sagittal, vertical and transversal dimensions of the bone tissue

Abstract

Relevance. The article studies the primary canine premature extraction as the cause of three-dimensional (sagittal, transversal, vertical) bone underdevelopment in the area of the extracted tooth. The research is relevant as there are insufficient data in the scientific literature on this topic and the prevalence of premature primary canine extraction for therapeutic and orthodontic indications is high.Materials and methods. The present case study developed a special technique for bone volume measurement in all planes by CBCT.Results. Several CBCTs of one patient over the period of three years were analyzed according to the suggested technique. The calculations demonstrated significant sagittal and vertical bone loss.Conclusions. The results of the research allowed us to conclude that premature extraction of the primary canines leads to the significant sagittal and vertical bone loss. Besides, no increase in the intercanine distance was detected despite the patient’s growth spurt.
