Nowadays, there is an increased tendency for researches to focus on accelerating methods for tooth movement due to the huge demand for adults for a shorter orthodontic treatment time. Unfortunately, long orthodontic treatment time poses several disadvantages like higher predisposition to caries, gingival recession, and root resorption. This increases the demand to find the best method to increa...

Orthodontic tooth movement depends on favorable supporting tissues responding to the forces used during treatment. The tissues involved are the periodontal ligament (PDL), alveolar bone, cementum and dentin. Clast cells play an important role in the process of physiologic remodeling and mineralized tissue responses to external forces. They also play a significant role in unfavorable iatrogenica...

The periodontally accelerated osteogenic orthodontic (PAOO) technique combines selective decortication facilitated orthodontics with periodontal regeneration in order to create rapid orthodontic tooth movement (OTM). This reduces potential side ef devitalization, relapse, inadequate basal bone and bacterial time periodontal infection. Tooth movement can be achieved with increased alveolar volum...

Orthodontic force-induced stresses cause dynamic alterations within the extracellular matrix and within the cytoskeleton of cells in the periodontal ligament and alveolar bone, mediating bone remodelling, ultimately enabling orthodontic tooth movement. In the periodontal ligament and alveolar bone, the mechanically induced tensile strains upregulate the expression of osteogenic genes resulting ...

INTRODUCTION The purpose of this study was to investigate the effect of psychological stress on orthodontic tooth movement in Wistar rats. MATERIALS AND METHODS Forty-eight female ten-week old Wistar rats with an average weight of 188 ±12 gr were selected and randomly divided into two experimental and control groups. The experimental group received crowded environment-induced and cat odour st...

Periodontic-orthodontic interactions are mutually beneficial. Combined periodontic and orthodontic treatment can greatly enhance periodontal health and dentofacial esthetics. Adjunctive orthodontic management of pathological tooth migration has unique effects in subjects with moderate to advanced periodontitis. Orthodontic treatment should only be undertaken with healthy periodontium or healthy...

Orthodontic treatment observes resistance in areas of desired tooth movement and anchorage sites. Hence, proper orthodontic anchorage preparation is important to ensure predictable tooth movement and negating insufficient reciprocal movement [1]. Understanding each patient’s anchorage requirements is of paramount importance which ensures high-quality care. Unexpected or unintended anchorage los...

With an increasing number of adult patients coming to the orthodontic clinic, the orthodontic professional is constantly looking for ways to accelerate tooth movement. Surgical intervention to affect the alveolar housing and tooth movement has been described in various forms for over a hundred years. However, it is the spirit of interdisciplinary collaboration in orthodontics has expanded the r...
