Profiles of inflammation factors and inflammatory pathways around the peri-miniscrew implant.

Histol Histopathol 2021 Apr 9:18336. Epub 2021 Apr 9.

Department of Orthodontics, Stomatological Hospital, Southern Medical University, Guangzhou, China.

Background: Peri-miniscrew implant is a temporary assistant armamentarium for the treatment of severe malocclusion and complex tooth movement, the inflammation around it is the main reason for the failure of orthodontic treatment due to the implant loosening and falling out. Inflammation around the peri-miniscrew implant is associated with the release of pro-inflammatory cytokines. These pro-inflammatory cytokines, in turn, recruit immune cells (such as macrophages, dendritic cells, T cells, and B cells), which can produce and release inflammatory biomarkers, regulate the interaction between immune cells, periodontal ligament cells, osteoblasts, and so on.

Effects of orthodontic forces on bone turnover biomarkers in peri-miniscrew crevicular fluid: A systematic review.

Int Orthod 2020 Sep 22;18(3):403-411. Epub 2020 Apr 22.

Aristotle University of Thessaloniki, Department of Preventive Dentistry, Periodontology and Implant Biology, Thessaloniki, Greece.

Objective: Peri-miniscrew crevicular fluid (PMCF) analysis of biomarkers representing bone formation or resorption could provide a non-invasive way to monitor bone turnover around miniscrews and the response to force loading. Our objective was to systematically investigate the relevant available evidence.

Materials And Methods: Search without restrictions in eight databases and hand searching until March 2020 took place. Read More

Levels of TGF-β1 in peri-miniscrew implant crevicular fluid.

J Oral Biol Craniofac Res 2020 Apr-Jun;10(2):93-98. Epub 2020 Mar 6.

Centre for Biomedical Engineering, Indian Institute of Technology Delhi, New Delhi, 110016, India.

The peri-miniscrew implant crevicular fluid is analogous to gingival crevicular fluid, and its contents reflect the state of inflammation and health during the life of the miniscrews in the mouth. The stability of MSI is fundamental to its role as an anchorage. This study aimed to evaluate transforming growth factor-beta one (TGF-β1) of the peri-miniscrew implant crevicular fluid (PMICF), on implant insertion, pre- and post-loading of MSIs to find a clue to their role in the stability of MSI.

Influence of orthodontic loading on biomarkers levels around miniscrews.

Arch Oral Biol 2020 Apr 27;112:104668. Epub 2020 Jan 27.

Department of Orthodontics, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil.

Objective: The aim of this study was to evaluate the levels of Interleukin-1α (IL-1α), Interleukin-1β (IL-1β), Interleukin-1 receptor antagonist (IL-1Ra), Interleukin-10 (IL-10), Interleukin-13 (IL-13), Vascular endothelial growth factor (VEGF), Granulocyte-colony stimulating factor (G-CSF), and Growth related oncogene (GRO) in the peri-miniscrew implant crevicular fluid (MICF) under orthodontic loading.

Design: The study sample comprised 14 miniscrews immediately loaded and 17 unloaded ones. A load of 200gF was immediately applied to the miniscrews in the loaded group after the placement surgery. Read More

A review of biomarkers in peri-miniscrew implant crevicular fluid (PMICF).

Prog Orthod 2017 Nov 27;18(1):42. Epub 2017 Nov 27.

Centre for Biomedical Engineering, Indian Institute of Technology Delhi, New Delhi, India.

Background: The temporary anchorage devices (TADs) which include miniscrew implants (MSIs) have evolved as useful armamentarium in the management of severe malocclusions and assist in complex tooth movements. Although a multitude of factors is responsible for the primary and secondary stability of miniscrew implants, contemporary research highlights the importance of biological interface of MSI with bone and soft tissue in augmenting the success of implants. The inflammation and remodeling associated with MSI insertion or loading are reflected through biomarkers in peri-miniscrew implant crevicular fluid (PMICF) which is analogous to the gingival crevicular fluid.

OPG and RANKL levels around miniscrew implants during orthodontic tooth movement.

Am J Orthod Dentofacial Orthop 2013 Aug;144(2):203-9

Department of Periodontology, Faculty of Dentistry, Izmir Katip Celebi University, Izmir, Turkey.

Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor activator of nuclear factor-кB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded miniscrew implants at different time intervals.

Methods: Twenty loaded and 16 unloaded miniscrew implants were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars and first molars as anchorage units for canine distalization. Read More
