Oral Technology, Dental School, University Hospital Bonn, Bonn, Germany. Electronic address:
Objectives: To create a validated 3D finite element model and employ it to examine the biomechanical behaviour of multirooted root analogue implants (RAIs).
Methods: A validated finite element model comprising either an RAI or a threaded implant (TI) and an idealised bone block was developed based on a previously conducted in vitro study. All the experimental boundary conditions and material properties were reproduced.
Guide-wire and K-wire readjustment jig for osteotomy and osteosynthesis: An instrument.

Introduction: Numerous orthopaedic procedures including dynamic hip screw plating and various osteotomies require placement of a reference guide pin or K wire to direct bone cuts or for drilling screw holes. Appropriate positioning of these wires is a critical component of surgery. Irrespective of whether one is a seasoned surgeon or an apprentice, these wires often need repositioning and readjustment.

Objective: The endoscopic transsphenoidal approach is commonly used for sellar and suprasellar pathologies. However, reaching above the diaphragma sella, especially for posterosuperior and retrocavernous orientation, still poses some challenges. We designed and developed a steerable tip suction cannula (STSC) that has distinct leverage for endoscopic resection of such pathologies.

Instituto de Odontoestomatología, Escuela de Odontología, Facultad de Medicina, Universidad Austral de Chile, Valdivia, Chile.
Aim: To compare thequality and accuracy of radiographic images obtained by dentistry students from a Chilean university using photostimulable phosphor plates (PSP) and complementary metal oxide semiconductor (CMOS) receptors.
Materials And Methods: An experimental study was carried out in which 31 dental students used PSP and CMOS receptors to acquire radiographic images with the aid of a phantom. The time required to generate a radiograph was recorded.
Multivariable Analysis of Correlation Between Anatomical Features of Mandibular Third Molars and Pericoronitis.

Department of Oral Surgery, Faculty of Odonto-Stomatology, University of Medicine and Pharmacy at Ho Chi Minh City, Ho Chi Minh City, Vietnam.
The correlation between anatomy features of impacted mandibular third molars (M3Ms) and prevalence of pericoronitis was only interpreted using univariate analysis. This study investigated this correlation using multivariable analysis to determine the relationship between pericoronitis prevalence and the M3Ms' anatomical features. This cross-sectional study recruited 245 patients with 338 impacted M3Ms.
