Severe unilateral scissors‐bite with a constricted mandibular arch: Bite turbos and extra‐alveolar bone screws in the infrazygomatic crests and mandibular buccal shelf

American Journal of Orthodontics and Dentofacial Orthopedics, 2018
&NA; A 33‐year‐old woman had a chief complaint of difficulty chewing, caused by a constricted mandibular arch and a unilateral full buccal crossbite (scissors‐bite or Brodie bite).

Analysis of Locking Self-Taping Bone Screws for Angularly Stable Plates

Journal of Medical and Biological Engineering, 2017
Paper focuses on biomechanics, specifically on locking cortical bone screws in angularly stable plates used for the treatment of bone fractures in the medical fields of traumatology and orthopaedics. During extraction of titanium-alloy implants, problems

Cortical bone trajectory fixation cause low compression force in anterior vertebral column

North American Spine Society Journal, 2022
Background: The cortical bone trajectory (CBT) screws follow a caudocephalad and lateral path from the pedicle to the vertebral body. The bone fusion rate of CBT fixation is equal to or lower than conventional pedicle screw fixation.

Impact of bone density and integrated screw configuration on standalone anterior lumbar interbody construct strength

North American Spine Society Journal
Background: In anterior lumbar interbody fusion (ALIF), the use of integrated screws is attractive to surgeons because of the ease of implantation and no additional profile.

A new concept for implant fixation: bone-to-bone biologic fixation [PDF]

European Cells & Materials, 2015
Many attempts have been made to reduce complications of bone implant, such as pedicle screw loosening. To address this problem, the authors suggest a new concept of bone-to-bone biologic fixation using recombinant human bone morphogenetic protein-2 ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.
