Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

Acoustic comparison of PET and Latex wings for flapping micro-air-vehicles

, 2015
This paper presents the hyper-elastic Latex film as the new material for flapping wings novelly. Compared to one of the conventional flapping wings using PET, the new Latex wing reduces the noise with 15.93 dB at least.

Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style

Journal of Anatomy, EarlyView.
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.

A digital workflow for full‐arch implant fixed prosthesis: Clinical application of a 3D‐printed polychromatic flangeless trial denture, anatomic bone reduction guide, and intraoral scanning for definitive prosthesis fabrication

Journal of Prosthodontics, EarlyView.
Abstract This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full‐arch, implant‐supported fixed dental prosthesis (FP‐1). It highlights the integration of a 3D‐printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling ...
