This paper presents an implantable package aimed at hosting a bidirectional neural interface for neural prosthetic applications. The package has been conceived to minimize the invasivity for the patient, for this reason a cylindrical container with an outer diameter of 7 mm and a length of 21 mm has been designed. The package, realized in alumina (Al2O3), presents 32 hermetic feedthroughs located at the top and bottom base of the cylinder. The hermetic housing has been assembled using a low-temperature soldering method based on a previous platinum/gold (Pt/Au) metallization of the ceramic parts. The package's hermeticity has been successfully proved by means of in-vitro tests, exhibiting an increase in the inner relative humidity of 20 %RH over 75 days of observation.

Silicon integrated circuits (ICs) are central to the next-generation miniature active neural implants, whether packaged in soft polymers for flexible bioelectronics or implanted as bare die for neural probes. These emerging applications bring the IC closer to the corrosive body environment, raising reliability concerns, particularly for chronic use. Here, we evaluate the inherent hermeticity of bare die ICs, and examine the potential of polydimethylsiloxane (PDMS), a moisture-permeable elastomer, as a standalone encapsulation material.

Background and objective Orthopedic surgery, particularly joint replacement, involves the use of many implants, resulting in a large amount of product packaging waste. To date, no study has surveyed artificial joint manufacturers on the recycling and reduction of packaging materials and their Sustainable Development Goal (SDG) initiatives. This questionnaire survey aimed to identify the current status of orthopedic artificial joint manufacturers in terms of implementing SDG initiatives.

: The measurement of Hounsfield units (HU) during implant treatment planning is important. Currently, various manufacturers' implant planning software programs offer HU capabilities; however, their accuracy remains unverified. In this study, we aimed to validate the accuracy of HU values measured by implant planning software programs.

Purpose: To study the correlation between the levels of inflammatory factors in gingival crevicular fluid and implant stability and prognosis after oral implant restoration.

Methods: A total of 78 patients who underwent oral implant restoration surgery from August 2022 to August 2023 were selected as the experimental group. According to the results of X-ray examination 1 month after implantation, the patients were divided into poor prognosis subgroup(n=33) and good prognosis subgroup(n=45), another 60 healthy subjects who underwent physical examination during the same period were selected as the control group.
