One versus two anterior miniscrews for correcting upper incisor overbite and angulation: a retrospective comparative study

Progress in Orthodontics, 2020
Background Miniscrews are effective devices for performing upper incisor intrusion. Different mechanics can be applied depending on the treatment objectives.

Thread shape, cortical bone thickness, and magnitude and distribution of stress caused by the loading of orthodontic miniscrews: finite element analysis

Scientific Reports, 2022
Cortical bone thickness is assumed to be a major factor regulating miniscrew stability. We investigated stress distribution in two miniscrews with different thread shapes (type A and B) and in cortical bone of three different thicknesses using three ...

Evidence-based selection of orthodontic miniscrews, increasing their success rate in the mandibular buccal shelf. A randomized, prospective clinical trial

BMC Oral Health, 2022
Background Skeletal anchorage has made it possible to perform complex orthodontic tooth movements that are difficult or even impossible to achieve with conventional orthodontic treatment. Mandibular buccal shelf miniscrews, used for distalization, play a

Efficacy of Miniscrews in Gaining Prosthetic Space for a Dental Implant to Replace the Mandibular First Molar: A Case Series

Applied Sciences, 2021
Background: The objective of this case series was to evaluate the efficacy of miniscrews to upright the lower second molar as a result of early loss of the lower first molar in order to permit rehabilitation by means of an implant-supported single crown.

Geometry of anchoring miniscrew in the lateral palate that support a tissue bone borne maxillary expander affects neighboring root damage

Scientific Reports, 2021
Anchoring miniscrews used for a tissue bone borne maxillary expander (C-expander) can fail if they contact tooth roots or perforate the maxillary sinus. Cone beam computed tomography images were reviewed retrospectively to evaluate the geometric factors ...
