Mechanobiology of tooth movement.
This review describes the mechanical and biological signalling pathways during orthodontic tooth movement and provides an update of the current literature. A theoretical model is introduced to elucidate the complex cascade of events after the application of an orthodontic force to a tooth. In this model, the events are divided into four stages: matrix strain and fluid flow, cell strain, cell ac...
متن کاملEffect of Ovariectomy on Orthodontic Tooth Movement in Rats
Background and Aim: Estrogen affects the metabolism in females. This study aimed to assess the effect of absence of estrogen on orthodontic tooth movement in rats. Materials and Methods: In this animal study, 55 rats were randomly divided into four groups. Group 1 (n=10) had intact ovaries. In group 2 (n=15), ovaries were intact but the rats were subjected to stress due to tooth preparation. I...
متن کاملThe effect of caffeine on orthodontic tooth movement in rats
Objective(s): to determine the effect of different doses of caffeine on orthodontic tooth movement (OTM) in rats. Materials and Methods: Forty male 250-300 g Sprague-Dawley rats were randomly divided into four groups of ten animals each and received 0 (control), 1 g/l, 2 g/l and 3 g/l caffeine in tap water for 3 days. Orthodontic appliances were ligated between the maxillary first molars and in...
متن کاملA method of Bender applied to groups of J3-type
We apply a method of Bender [6] to determine the order of a group G of J3-type. Moreover, we determine the local p-structure of G for every prime p dividing the order of G. The results of this paper are obtained by exploiting the action of G on its geometry [4] and by sophisticated use of elementary group theory.
متن کاملMechanisms of tooth eruption and orthodontic tooth movement.
Teeth move through alveolar bone, whether through the normal process of tooth eruption or by strains generated by orthodontic appliances. Both eruption and orthodontics accomplish this feat through similar fundamental biological processes, osteoclastogenesis and osteogenesis, but there are differences that make their mechanisms unique. A better appreciation of the molecular and cellular events ...
