The natural aging process of the human organism leads to both physiological and pathological changes, including tooth loss. This requires dental prosthetic interventions aimed at restoring patients' quality of life. The use of such prostheses necessitates selection of sufficiently strong, aesthetic and biocompatible materials, which also offer ease of shaping. The market for materials used in prosthetic applications offers a wide array of options; however, selection of the most suitable material for specific clinical scenarios can be challenging for dental professionals. This paper continues the comprehensive investigation of the physiochemical and mechanical/functional properties of two commonly used prosthetic-Biocetal and BioHPP-offering a comparative analysis of their characteristics to provide valuable insights for dentists and prosthodontists. The study focuses on in vitro analyses of physiochemical parameters, including density, water sorption, contact angle, and surface roughness. The structure of the materials was examined via scanning electron microscopy. Additionally, microbiological studies were performed using strains of , , , and . Statistical analysis was performed using Shapiro-Wilk test, Q-Q plot analysis, Grubbs test, and Student's T-test ( < 0.05). The findings indicate that BioHPP demonstrates superior physiochemical and microbiological properties. However, Biocetal exhibit better surface characteristics. Despite its high performance, BioHPP presents certain drawbacks, which may influence dentists' material choice in specific clinical cases, particularly for certain prosthetic restorations.

Neuroprostheses capable of providing Somatotopic Sensory Feedback (SSF) enables the restoration of tactile sensations in amputees, thereby enhancing prosthesis embodiment, object manipulation, balance and walking stability. Transcutaneous Electrical Nerve Stimulation (TENS) represents a primary noninvasive technique for eliciting somatotopic sensations. Devices commonly used to evaluate the effectiveness of TENS stimulation are often bulky and main powered.

Purpose: This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant-supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.
Materials And Methods: Three cylinder-shaped master files (20 mm long and 11 mm wide) with varying heights (7, 11, and 15 mm) and a titanium-base (Ti-base) abutment space were designed. These designs were used to fabricate a total of 144 specimens with two AM resins indicated for definitive use (Crowntec; AM-CT and Flexcera Smile Ultra+; AM-FS), one high-impact polymer composite (breCAM.

Purpose: This study aimed to compare the dimensional and positional deviations of additively manufactured removable dies fabricated using two bio-based resins and one conventional dental cast resin, while also evaluating these outcomes over a 4-week period.
Materials And Methods: A right mandibular first molar preparation on a typodont was scanned to digitally design removable dies and hollow partial arch casts. Based on a priori power analysis, a total of 30 dies (n = 10) and three hollow casts (n = 1) were fabricated using additive manufacturing (AM) from three different dental cast resins: DentaMODEL (DM), FotoDent bio-based model (CB), and soy-based resin (SB).

Purpose: The purpose of this study was to evaluate the survival outcomes of dental implants placed in the pterygoid region and assess the potential influence of multiple clinical variables on their survival.
Materials And Methods: A retrospective chart review was conducted on pterygoid implants placed over a 9-year period at the University of Connecticut Department of Prosthodontics. All pterygoid implants were placed by a single board-certified prosthodontist following a standardized surgical protocol.
