By using traditional casting procedures, accurately fitting of complete-arch frameworks that are screwed on multiple implants is difficult to achieve. The introduction of computer-aided design and manufacturing (CAD/CAM) techniques for fabricating custom 1-piece titanium frameworks simplifies this challenge and reduces time spent by the restorative dentist. This report presents a milled titanium complete-arch mandibular framework using a new planning software and a new scanner using non-contact laser probe, which eliminates the need for wax pattern fabrication.

This narrative review aimed to evaluate the effectiveness of computer-aided design (CAD), computer-aided manufacturing (CAM) milled, and direct metal laser sintering (DMLS) titanium frameworks in hybrid denture prostheses. A structured PICO analysis and a review of ten publications were used to compare titanium frameworks for hybrid dentures made through milling, DMLS, and CAD-CAM milling. Prosthesis success, bone loss, patient satisfaction, framework fit, and biofilm adhesion were among the outcome indicators.

Full-arch zirconia restorations on implants have gained popularity due to zirconia's strength and aesthetics, yet they are still associated with challenges like structural fractures, peri-implant complications, and design misfits. Advances in CAD/CAM and digital workflows offer potential improvements, but a technique that consistently addresses these issues in fixed, full-arch, implant-supported prostheses is needed. This novel technique integrates a facially and prosthetically driven treatment approach, which is divided into three phases: data acquisition, restoration design, and manufacturing/delivery.

The gold standard of microfluidic fabrication techniques, SU-8 patterning, requires photolithography equipment and facilities and is not suitable for 3D microfluidics. A 3D printer is more convenient and may achieve high resolutions comparable to conventional photolithography, but only with select materials. Alternatively, 5-axis computer numerical control (CNC) micro-milling machines can efficiently prototype structures with high resolutions, high aspect ratios, and non-planar geometries from a variety of materials.

The following case report presents the treatment of a patient with severe maxillary atrophy and failing residual dentition. The patient has been diagnosed with stage IV grade C periodontitis, making this case challenging from the very beginning. The treatment plan was based on collecting and merging digital data: CBCT, a face scan, and an intraoral scan.

Previous studies report rare occurrences of tibial baseplate fractures following primary total knee arthroplasty (TKA). However, at a microstructural scale, it remains unclear how fatigue models developed in vitro apply to fractures in vivo. In this study, we asked: (1) do any clinical factors differentiate fracture patients from a broader revision sample; and (2) in vivo, how does microstructure influence fatigue crack propagation? We identified three fractured tibial baseplates from an institutional review board exempt implant retrieval program.
