Case: We report a case of acetabular reconstruction for a large defect with pelvic discontinuity that underwent 4 revisions for dislocations over a 3-year period. This allowed assessment of implant stability both on imaging, using measurements on plain radiographs and radiostereometric analysis (RSA) against both ilium and ischium, and direct assessment during each surgery. Only implant stability measured with RSA correlated with intraoperative revision findings.
Conclusion: This case underlines the role of RSA in assessing early acetabular implant stability in pelvic discontinuity and the importance of assessing the stability of the implant against both ilium and ischium.

Globular proteins, traditionally regarded as non-structural biomolecules due to the limited load-bearing capacity in their monomeric states, are increasingly recognized as valuable building blocks for functional-mechanical materials. Their inherent bioactivity, chemical versatility, and structural tunability enable the design of materials that combine biological functionality with tailored mechanical performance. This review highlights recent advances in engineering globular proteins-spanning natural systems (serum albumins, enzymes, milk globulins, silk sericin, and soy protein isolates) to recombinant architectures including tandem-repeat proteins-into functional-mechanical platforms.

Statement Of Problem: Despite high survival rates of implant-supported single crowns, retention loss remains common and decementation of crowns can compromise long-term stability, patient satisfaction, and treatment costs. Limited long-term evidence on cement type, abutment design, and materials requires further research to optimize clinical outcomes.
Purpose: The aim of this retrospective clinical study was to analyze the survival and decementation rates of zirconia and metal-ceramic implant-supported crowns in combination with different abutments (prefabricated or custom and unabraded or airborne-particle abraded).

Purpose: This study aimed to evaluate the performance of 3D-printed denture base resins (DBRs) compared with conventionally printed DBRs, examine their biofilm formation and physical properties, and determine the viability of 3D-printed DBRs as a superior alternative in removable prosthodontics.
Methods: The DBR samples were fabricated using traditional packing (TRA), milling (MIL), and 3D printing (3DP) methods. All samples were serially polished with an abrasive paper.

Objective: Aim: To evaluate the possibility of using cataract phacoemulsification with simultaneous intraocular lens (IOL) implantation in patients with age-related cataract (ARC) combined with pseudoexfoliation syndrome (PES) as an algorithm for the pseudoexfoliation glaucoma (PEG) prevention..
Patients And Methods: Materials and Methods: A retrospective case-control study was conducted using data from medical records of 610 outpatients (813 eyes) with ARC aged from 49 to 79 years (average age 69 ± 3 years).

Background: Choosing the appropriate implants for reconstruction in revision TKA is essential for long-term fixation. While cones and augments are routinely utilized to address tibial defects, the effect of augment location and size on the biomechanical stability of revision TKA constructs and the indications for the use of metaphyseal cones are not known.
Questions/purposes: Is the risk of cement-implant debonding of revision TKA constructs impacted by the thickness and location (medial versus bicompartmental) of tibial augments and the presence of metaphyseal cones during (1) a demanding daily activity like stair ascent and (2) torsional loads?
Methods: Under institutional review board approval, we developed patient-specific finite-element models of revision TKA from four patients (three males and one female, ages 50 to 80 years, BMI 27 to 37 kg/m2) who underwent two-stage revision and had a CT scan with no metal artifact after first-stage implant removal.
