The aim of this case report was to introduce the clinical use of a prosthetic soft tissue level implant and a completely digitized workflow for the production of an individualized suprastructure fixated on prosthetic implants for orthodontic anchorage reinforcement. A prosthetic soft tissue level implant was placed in the palatal region for orthodontic anchorage reinforcement. Based on an intraoral optical scan taken after implant osseointegration, the orthodontic suprastructure was manufactured entirely by means of computeraided design and manufacturing (CAD/CAM). The individualized suprastructure was subsequently loaded in direct manner. The prosthetic implant was then removed in a noninvasive manner, similar to palatal implants.The analysis included clinical and laboratory fabrication steps. The placement of prosthetic implant in the palatal region proved to be a painless, easy and fast procedure, and provided absolute anchorage during the entire intended orthodontic treatment. Its noninvasive removal did not cause any adverse patient reactions. The digitally constructed suprastructure did not require any chairside adaptation at delivery and was successfully used for the intended orthodontic treatment.The reported case presents the successful placement, loading and removal of a prosthetic soft tissue level implant for orthodontic anchorage use in the palatal region. The described digital and modelfree workflow provides a feasible and streamlined treatment modality for the fabrication of individualized orthodontic suprastructures by means of CAD/CAM for the use as orthodontic anchorage reinforcement. This proof of principle should be substantiated with further largerscaled investigations.

The escalating prevalence of skeletal muscle disorders highlights the critical need for innovative treatments for severe injuries such as volumetric muscle loss. Traditional treatments, such as autologous transplants, are constrained by limited availability and current scaffolds often fail to meet complex clinical needs. This study introduces a new approach to volumetric muscle loss treatment by using a shape-memory polymer (SMP) based on block copolymers of perfluoropolyether and polycaprolactone diol.

Walking on compliant terrains, like carpets, grass, and soil, presents a unique challenge, especially for individuals with mobility impairments. In contrast to rigid-ground walking, compliant surfaces alter movement dynamics and increase the risk of falls. Understanding and modeling gait control across such soft and deformable surfaces is thus crucial for maintaining daily mobility.

Background: Anatomically formed healing abutments were suggested in literature to address many of the issues associated with immediate posterior implant insertion such as large extraction sockets that are extremely hard to seal without reflecting the mucoperiosteal flap, extraction sockets anatomy that are not suitable for regular healing abutment placement, and potentially high occlusal stresses when planning a temporary implant supported prothesis to improve the conditioning of supra implant tissue architecture and the emergence profile of the implant supported restorations.
Purpose: To clinically evaluate the peri-implant soft tissue profile of single posterior implant retained restorations and to assess patient related outcomes of the implant restorations that were conditioned immediately by CAD-CAM socket sealing abutments (SSA) versus those conditioned by Titanium (Ti) standard healing abutments (SHA).
Methods: Twenty participants received twenty-two single maxillary immediate implants after flapless minimally invasive tooth extraction and 3D guided implant placement in the posterior area (premolar and molar) and allocated randomly into two groups (n = 11), the intervention group: patients received PEEK SSA and the control group: the patients received Ti SHA.

Soft actuators hold great potential for applications in surgical operations, robotic manipulation, and prosthetic devices. However, they are limited by their structures, materials, and actuation methods, resulting in disadvantages in output force and dynamic response. This article introduces a soft pneumatic actuator capable of bending based on triangular prism origami.

Despite the advances in bionic reconstruction of missing limbs, the control of robotic limbs is still limited and, in most cases, not felt to be as natural by users. In this study, we introduce a control approach that combines robotic design based on postural synergies and neural decoding of synergistic behavior of spinal motoneurons. We developed a soft prosthetic hand with two degrees of actuation that realizes postures in a two-dimensional linear manifold generated by two postural synergies.
