Human cell conversion technology has become an important tool for devising new cell transplantation therapies, generating disease models and testing gene therapies. However, while transcription factor over-expression-based methods have shown great promise in generating cell types in vitro, they often endure low conversion efficiency. In this context, great effort has been devoted to increasing the efficiency of current protocols and the development of computational approaches can be of great help in this endeavor. Here we introduce a computer-guided design tool that combines a computational framework for prioritizing more efficient combinations of instructive factors (IFs) of cellular conversions, called IRENE, with a transposon-based genomic integration system for efficient delivery. Particularly, IRENE relies on a stochastic gene regulatory network model that systematically prioritizes more efficient IFs by maximizing the agreement of the transcriptional and epigenetic landscapes between the converted and target cells. Our predictions substantially increased the efficiency of two established iPSC-differentiation protocols (natural killer cells and melanocytes) and established the first protocol for iPSC-derived mammary epithelial cells with high efficiency.

Traditionally, clinical devices are designed, tested and improved through lengthy and expensive laboratory experiments and clinical trials [1]. More recently, computational methods have allowed for rapid testing, speeding up the design process and enabling far more complete searches of design space. While computational models cannot fully capture the complexities of biological systems, they provide valuable insights into crucial underlying mechanisms, such as the effects of fluid-structure interactions (FSIs).

: The retreatment of failed dental implants remains a challenging clinical scenario, particularly when complicated by peri-implantitis and as sociated bone loss. Successful management requires a comprehensive and predictable approach that addresses both hard and soft tissue deficiencies. This case report illustrates a fully digital, prosthetically driven workflow for the rehabilitation of a posterior mandibular site following implant failure.

Objective: The purpose of this article is to present a digital workflow to resolve functional-esthetic conflicts in severe generalised tooth surface loss (TSL).
Clinical Considerations: Key challenges in TSL involved compromised structural integrity of the dentition, necessitating precise occlusal rehabilitation to achieve a stable mandibular position and occlusion. The virtual patient-derived protocol introduced two technical advancements: (1) maxillomandibular relationship (MMR) determination through jaw kinematics capture, and (2) dynamic anterior guidance optimization via jaw motion tracking and dynamic articulation simulation.

Background: Computer-guided surgery has played a crucial role in planning alveolar ridge augmentation. In the last decade, various software programs have been used in computer-guided fabricated nonresorbable membranes, including zirconia membranes, for guided bone regeneration. However, most of these software programs are not free of charge.

Objective: To evaluate the feasibility and clinical outcomes of computer-guided injection of sodium hyaluronate visco-supplementation and arthrocentesis in the treatment of temporomandibular joint disorder compared with conventional injection.
Study Design: Twenty patients with Wilkes stage I & II internal derangement were selected and randomly allocated into the intervention group, managed with computer-guided intra-articular visco-supplementation, and the control group, managed with conventional technique. The efficacy of the computer-guided procedure was appraised by the assessment of the need for needle relocation and the duration of the procedure in both groups.
