Experimental animal studies have shown that orthodontic forces & tooth movements do not induce gingivitis in the absence of plaque. However similar forces can induce angular bone defects in the presence of plaque. Orthodontic tooth movements like tipping & intrusion can cause attachment loss in the presence of by: 4. Diabetes mellitus (DM) may adversely affect periodontal tissues during orthodontic tooth movement (OTM). The aim of this review is to systematically analyze and review animal studies investigating the effect of DM on periodontal tissues during OTM.

Abstract. Abstract The purpose of the experiment reported was to study soft tissue changes at teeth which were orthondontically moved into areas with varying thickness and quality of periodontal tissues. The maxillary central incisors and first premolars in 5 adult monkeys were used as experimental teeth. 6 months prior to the start of the orthodontic treatment phase, . A variety of outcome measures have been used to determine the effect of orthodontic tooth movement on the pulp, including effects at a tissue level (pulpal inflammation, pulpal degeneration, cellularity, fibrotic changes, predentine width, reparative dentine formation, pulpal space obliteration, Hertwig's epithelial root sheath), cellular level (pulp cell .
wounded periodontium. Materials and Methods: Orthodontic tooth movement was introduced 24 hours before transplan-tation of PL or ES cells, and rats were euthanized either 24 hours or 72 hours after cell trans-plantation. The control rats received either no tooth movement and no cell transplantation or tooth movement and no cell by: The Biomechanical Function of Periodontal Ligament Fibres in Orthodontic Tooth Available via license: CC BY Content may be subject to copyright.

Orthodontic forces are capable of reorganizing and remodeling the periodontal ligament, to facilitate tooth movement. Optimal forces will produce favorable tissue responses, but whenever this balance is lost (as in the case of high force magnitudes, or in the presence of reduced periodontal support), the periodontal ligament may respond by: Observations of soft and hard periodontal tissues' changes during the orthodontic tooth movement (OTM) in orthodontic and periodontal literature will be Cited by: 9.
The orthodontic tooth movement (OTM) exerts physical, bio- physical and biochemical effects on the ECM and constituent cells of the periodontium and dental pulp [2,]. In turn, orthodontic movement causes reori-entation and remodeling of periodontal support tissues during tooth movement, but the applica-tion of appropriate mechanical forces causes ex-pected reactions in the periodontal tissue sup-port.

Root resorption is a common consequence associated with orthodontic treatment. It has received considerable attention because of medicolegal exposure.
It appears that apical root resorption results from a combination of individual biological variability and the effect of. When orthodontic forces are exerted on a tooth or teeth, changes in the periodontal structures (cementum, periodontal fibers, gingival fibers, and alveolar bone) can be observed on the pressure and tension sides of the tooth.
When the periodontium of the teeth submitted to orthodontic movement is normal, good “bone balance” is achieved, and the amount of neo bone built in the deposition side equalizes the bone deficit between resorption and deposition in the resorption side.
Orthodontic movement creates clinical, cel-lular, and molecular level changes in the alve-olar bone. In periodontal pressure sites, bone resorption occurs by osteoclasts, while in the periodontal tension sites, bone apposition oc-curs by osteoblasts. Orthodontically generated dental movement thus is strictly related to phys.

implants; 7) It decreases or eliminates effects of bruxism, as pain or muscle spasms, during the orthodontic therapy; 8) With the current available orthodontic technology and with correct planning and execution, it allows precise, light and efficient orthodontic movements.
vertical orthodontic tooth repositioning can improve certain types of osseous defects in periodontal patients. often the tooth movement eliminates the need for resective osseous surgery 4. orthodontic treatment can improve the esthetic relationship of the maxillary gingival margin levels before restorative dentistry.5/5(4).
There are osteogenic changes seen in bone during orthodontic tooth movement, and there will be alteration of bone deformities and contours. The topography of the underlying bone and other intraosseous deformities influences the prognosis of periodontal therapy and pockets : Luv Agarwal, Ragni Tandon, Shrish Srivastava, Ankit Gupta.
Short-term and long-term effects of orthodontic treatment on the periodontium. Plaque is a major etiologic factor in the development of gingivitis. Results from past animal studies[28–31] done in dentitions with reduced periodontium show that in the absence of plaque, orthodontic forces and tooth movements do not induce the presence of plaque.
When oral hygiene is well controlled, the use of intrusive orthodontic forces might promote desirable periodontal changes. 48 Orthodontic movements must be delivered throughout light forces. 49 When oral hygiene is deficient, the intrusive movement may facilitate the presence of dental biofilm in the sub-gingival region, provoking or.
Accelerated orthodontic tooth movement has been recently the topic of interest for orthodontic practitioners. Increased numbers of both clinical and research articles associated with the accelerated orthodontic treatment have been published in peer-reviewed journals in the last couple of years.

Orthodontic dogma is considered to be the one according to which the movement of the tooth in the periodontal space occurs by the effect of two dominant forces: pressure force (compression) and tensile strength (tension) [ 7 ].
As a result of the pressure Cited by: 2. CHANGES IN PDL DURING ORTHODONTIC TREATMENT: Yoshiki Nakamura in AJO studied the degenerating tissue changes in the PDL during tooth movement.
There were two types of degenerating tissues found in the compressed periodontal ligaments: 1. type A tissue stained differently from collagen and the other 2. type B tissue showed the same .Scanned dental casts are used to create a digital model to which small changes are then made to produce a stereolithographic cast on which the aligner is made.
Subsequent incremental changes to the digital model are used to produce a matching series of altered casts for construction of a sequence of aligners.Rygh P () Ultrastructural cellular reactions in pressure zone of rat molar periodontium incident to orthodontic tooth movement.
