Tooth autotransplantation is defined as the surgical repositioning of an autogenous tooth in another surgical site within the same individual. The aim of this research was to analyze the outcome of tooth transplantation using immature donor teeth compared with closed apex teeth and to compare differences between donor tooth positions on the arch. Electronic and manual literature searches were performed in different databases, including the National Library of Medicine (MEDLINE), EMBASE (OVID), Cochrane Central (CENTRAL), and the digital library of the Universitat Internacional de Catalunya (UIC University) from 1978 to March 2021.

Clinical and Radiographic Outcomes of Zirconia Dental Implants-A Clinical Case Series Study.

Accuracy of static fully guided implant placement in the posterior area of partially edentulous jaws: a cohort prospective study.

Objective: A cohort prospective study was conducted to assess the three-dimensional positioning accuracy of the implant between pre-surgical and the final implant position using a static fully guided approach in the posterior area of the jaws.

Materials And Methods: A total of 60 implants (30 patients) were digitally analyzed after superimposing the Digital Imaging and Communications in Medicine (DICOM) files obtained from the Cone Beam Computed Tomography (CBCT) pre- and post-implant placement.

Purpose: To assess the hard tissue dimensional changes following implant removal due to peri-implantitis.

Material And Methods: Clinical records were examined to identify patients with implants that had to be removed due to a hopeless prognosis secondary to peri-implantitis due to expendability of peri-implantitis implants for functional reasons.
