The study on PAOO minimally invasive versus traditional surgery in accelerating orthodontic tooth movement and its mechanisms [PDF]

open access: yesKouqiang yixue
Objective To compare the periodontally accelerated osteogenic orthodontics(PAOO) effects of corticotomy with full mucoperiosteal flap(flapped corticotomy) and corticotomy-only on accelerating orthodontic tooth movement. Methods A total of 60 healthy male

On tooth movement.

open access: yesThe Angle orthodontist, 1994
Current concepts of clinical orthodontic tooth movement are misleading. Traditionally, these have been described as dependent on force levels and being tipping/bodily in nature. The following is a reevaluation of the relationships between tooth movement and orthodontic mechanotherapy not usually considered when analyzing tooth movement clinically.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

open access: yesThe Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

The Effect of Low-Level Laser Therapy on Accelerating Tooth Movement in Orthodontic Patients: A Randomized Controlled Trial

open access: yesJournal of Pharmacy and Bioallied Sciences
Background: An adjuvant treatment, known as low-level laser therapy (LLLT), has been suggested to quicken orthodontic tooth movement and perhaps shorten the course of treatment. Materials and Methods: For 60 orthodontic patients aged between 15 and 25, a

The role of active ingredients nanopowder Stichopus hermanii gel to bone resorption in tension area of orthodontic tooth movement

open access: yesDental Journal, 2017
Background: Orthodontic tooth movement is a continual and balanced process between bone deposition and bone resorption in pressure and tension sites. Stichopus hermanii is one of the best fishery commodities in Indonesia.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Alveolar Bone Formation by Orthodontic Movement

open access: yesČeská Stomatologie a Praktické Zubní Lékařství, 2012
Objectives: The ability to move tooth trough alveolar bone is one of the basic principles in orthodontics. Mechanical force generated by orthodontic appliance is transferred to periodontal ligament resulting in the remodeling of alveolar bone.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.
