AO Distal Radius Fracture Classification: Global Perspective on Observer Agreement.

 The primary objective of this study was to test interobserver reliability when classifying fractures by consensus by AO types and groups among a large international group of surgeons. Secondarily, we assessed the difference in inter- and intraobserver agreement of the AO classification in relation to geographical location, level of training, and subspecialty.  A randomized set of radiographic and computed tomographic images from a consecutive series of 96 distal radius fractures (DRFs), treated between October 2010 and April 2013, was classified using an electronic web-based portal by an invited group of participants on two occasions.

Application of calcium phosphates and fibronectin as complementary treatment for osteoporotic bone fractures.

Introduction: The gradual aging of the population results in increased incidence of osteoporotic bone fractures. In a good quality bone, the fixation with the usual methods is adequate, but not in osteoporotic bone, in which consolidation delays and other complications are common, with failure rates for screws up to 25%.

Objective: To test fibronectin loaded hydroxyapatite as a complementary treatment for osteoporotic fractures.

Accuracy of a Digital Impression System Based on Active Triangulation Technology With Blue Light for Implants: Effect of Clinically Relevant Parameters.

Purpose: To evaluate the accuracy of a digital impression system considering clinical parameters.

Materials And Methods: A master model with 6 implants (27, 25, 22, 12, 15, and 17) was fitted with polyether ether ketone scan bodies. Implant no.

Accuracy of two digital implant impression systems based on confocal microscopy with variations in customized software and clinical parameters.

Purpose: To evaluate the accuracy of two digital impression systems based on the same technology but different postprocessing correction modes of customized software, with consideration of several clinical parameters.

Materials And Methods: A maxillary master model with six implants located in the second molar, second premolar, and lateral incisor positions was fitted with six cylindrical scan bodies. Scan bodies were placed at different angulations or depths apical to the gingiva.

Accuracy of a digital impression system based on parallel confocal laser technology for implants with consideration of operator experience and implant angulation and depth.

Purpose: To evaluate the accuracy of a digital impression system based on parallel confocal red laser technology, taking into consideration clinical parameters such as operator experience and angulation and depth of implants.

Materials And Methods: A maxillary master model with six implants (located bilaterally in the second molar, second premolar, and lateral incisor positions) was fitted with six polyether ether ketone scan bodies. One second premolar implant was placed with 30 degrees of mesial angulation; the opposite implant was positioned with 30 degrees of distal angulation.

Using stereophotogrammetric technology for obtaining intraoral digital impressions of implants.

Background: The procedure for making impressions of multiple implants continues to be a challenge, despite the various techniques proposed to date. The authors' objective in this case report is to describe a novel digital impression method for multiple implants involving the use of stereophotogrammetric technology.

Case Description: The authors present three cases of patients who had multiple implants in which the impressions were obtained with this technology.

Impression of multiple implants using photogrammetry: description of technique and case presentation.

Aim: To describe a technique for registering the positions of multiple dental implants using a system based on photogrammetry. A case is presented in which a prosthetic treatment was performed using this technique.

Study Design: Three Euroteknika® dental implants were placed to rehabilitate a 55-year-old male patient with right posterior maxillary edentulism.

Accuracy of a digital impression system based on active wavefront sampling technology for implants considering operator experience, implant angulation, and depth.

Background: There is a scarce knowledge on the accuracy of intraoral digital impression systems for dental implants.

Purpose: The purpose of this study is to evaluate the accuracy of a digital impression system considering clinical parameters.

Materials And Methods: A master model with six implants (27, 25, 22, 12, 15, 17) was fitted with polyether ether ketone scan bodies.

A clinical protocol for intraoral digital impression of screw-retained CAD/CAM framework on multiple implants based on wavefront sampling technology.

Purpose: To obtain an accurate CAD/CAM metal framework over 6 implants using a Chairside Intraoral Scanner based on the principle of active (optical) wavefront sampling.

Material And Methods: Six prototype cylindrical scan bodies screwed in the implants were used to obtain an intraoral digital impression. A conventional resin tooth try-in was fabricated and digitized with an extraoral scanner, and this dataset was merged to the digital data obtained from the intraoral impression to calculate the best framework design with advanced CAD software.
