Periodontally accelerated osteogenic orthodontics combined with recombinant human bone morphogenetic protein-2: An outcome assessment.

Context: Periodontally accelerated osteogenic orthodontics (PAOO) combines alveolar corticotomy, bone graft materials, and the application of orthodontic forces for rapid correction of malocclusions.

Aims: The present study aims to primarily assess differences in orthodontic treatment duration, bone quality around corticotomy sites, postoperative healing, and subjective pain when corticotomy was done conventionally and with the placement of recombinant human bone morphogenetic protein-2 (rhBMP-2).

Settings And Design: Thirty individuals participated in this study.

Influence of conventional and skeletal anchorage system supported fixed functional appliance on maxillo-mandibular complex and temporomandibular joint: A preliminary comparative cone beam computed tomography study.

Aim: Fixed functional appliance (FFA) used in the treatment of Class II malocclusion, lead to mandibular anterior teeth proclination, thus limiting the skeletal effects of the appliance. To counter this side effect, FFA is anchored in the lower anterior region of the mandible using the skeletal anchorage system. This pilot study was done to evaluate treatment and one-year post-treatment maxillo-mandibular, and temporomandibular joint (TMJ) effects of conventional fixed functional appliance (FFA) and skeletal anchorage system supported fixed functional appliance (SAS-FFA) using cone beam computed tomography (CBCT) images.

Comparison and evaluation of stresses generated by rapid maxillary expansion and the implant-supported rapid maxillary expansion on the craniofacial structures using finite element method of stress analysis.

Background: The study aimed to evaluate and compare the stress distribution and 3-dimensional displacements along the craniofacial sutures in between the Rapid maxillary Expansion (RME) and Implant supported RME (I-RME). METHODS: Finite element model of the skull and the implants were created using ANSYS software. The finite element model thus built composed of 537692 elements and 115694 nodes in RME model & 543078 elements and 117948 nodes with implants model.

Comparative evaluation and influence on shear bond strength of incorporating silver, zinc oxide, and titanium dioxide nanoparticles in orthodontic adhesive.

Objective: To investigate the influence of silver (Ag), zinc oxide (ZnO), and titanium dioxide (TiO) nanoparticles on shear bond strength (SBS).

Materials And Methods: One hundred and twenty extracted premolars divided into four groups with thirty specimens in each group. Group 1 (control): brackets (American Orthodontics) were bonded with Transbond XT primer.

Revolution in Orthodontics: Finite element analysis.

Engineering has not only developed in the field of medicine but has also become quite established in the field of dentistry, especially Orthodontics. Finite element analysis (FEA) is a computational procedure to calculate the stress in an element, which performs a model solution. This structural analysis allows the determination of stress resulting from external force, pressure, thermal change, and other factors.

Comparison of salivary calcium level in smokers and non-smokers with chronic periodontitis, aggressive periodontitis, and healthy controls.

Objective: The purpose of this study was to compare salivary calcium (Ca) level in smokers and non-smokers with chronic periodontitis, aggressive periodontitis, and healthy controls.

Materials And Methods: 56 subjects were included in the study and were grouped as follows: 12 subjects who were periodontally healthy (Group I), 12 subjects having chronic periodontitis who were non-smokers (Group II), 12 non-smokers having aggressive periodontitis (Group III), 12 smokers with chronic periodontitis (Group IV), and 8 smokers with aggressive periodontitis (Group V). Clinical measurements and non-stimulated whole saliva samples were obtained and analyzed for Ca levels by ion-selective electrolyte analyzer.
