The aim of this research was to study the impact of loading on partial dentures within the supporting soft tissue with respect to different attachment techniques. A finite element model was developed to calculate the stress and strain distribution in this tissue. The model consisted of the left half of a mandible with three remaining teeth that had suffered an atrophy in the anterior region, and a partial denture over the toothless area that was connected at the left mandibular canine using an attachment system. Resulting stress/strain distributions are presented for different load cases using a commercially available prefabricated attachment system.

Purpose: The positron range effect can impair PET image quality of Gallium-68 (Ga). A positron range correction (PRC) can be applied to reduce this effect. In this study, the effect of a tissue-independent PRC for Ga was investigated on patient data.

The internet has significantly transformed how news is produced, consumed, and distributed. As a result, the news industry has transitioned from ad-supported to subscription-based models regulated by digital paywalls. In the light of this disruption, it is crucial to investigate not only how news consumers adapt to this change but also how economic incentives shape content coverage.

Non-surgical rhinoplasty with hyaluronic acid (HA) filler is a three-dimensional reshaping technique that achieves tissue enhancement by placing HA deep to nasal skin. Due to its unique rheology, Restylane® Lyft (HA-L, Galderma, Uppsala, Sweden) may be particularly well-suited for injection rhinoplasty, as it has high gel firmness (G') for strong structural support with minimal integration propensity. A prospective clinical trial was conducted to evaluate HA-L use for non-surgical rhinoplasty.

The human body consists of many different soft biological tissues that exhibit diverse microstructures and functions and experience diverse loading conditions. Yet, under many conditions, the mechanical behaviour of these tissues can be described well with similar nonlinearly elastic or inelastic constitutive relations, both in health and some diseases. Such constitutive relations are essential for performing nonlinear stress analyses, which in turn are critical for understanding physiology, pathophysiology and even clinical interventions, including surgery.

Background: Closed preservation rhinoplasty continues to grow in popularity. Nevertheless, many surgeons remain wary of doing closed preservation rhinoplasty in certain patient populations. Mestizo noses have a thick soft-tissue envelope and weak nasal tip support.
