An in vitro trial on the effect of arch form on connector size requirements in long span anterior zirconia fixed dental prostheses.

Purpose: To test the fracture resistance of maxillary canine to canine fixed partial denture with four missing incisors, with increasing anterior-cantilevers of the pontics and varying connector sizes.

Materials And Methods: Two 3D-printed titanium alloy (Ti6Al4V) models mimicking a maxillary canine to canine fixed partial denture (FPD) with four pontics replacing the incisors were used as master models. Zirconia FPDs were digitally designed and milled with two different connector sizes (9 and 12 mm ) each with three different anterior cantilevers (7, 10, and 13 mm) accounting for 6 test groups.

Human Gingival Epithelial Growth In Vitro on a Polymer-Infiltrated Ceramic Network Restorative Material.

Purpose: To investigate the growth of primary human gingival epithelial (HGE) cells on polymer-infiltrated ceramic network (PICN) material (Vita Enamic) with different surface roughnesses.

Materials And Methods: PICN material specimens were polished with either silica carbide paper (grit-polished) or the manufacturer's polishing wheels (wheel-polished), and the surface roughness (R ) measured. HGE cells were seeded and grown for 1, 3, or 6 days.

Digital capture, design, and manufacturing of an extraoral device for a clarinet player with Bell's palsy.

An extraoral device was fabricated to assist a clarinet player with Bell's palsy. The device was fabricated by using stereophotogrammetry, digital design, and additive manufacturing technologies.

Digital capture, design, and manufacturing of a facial prosthesis: Clinical report on a pediatric patient.

A digitally captured, designed, and fabricated facial prosthesis is presented as an alternative to customary maxillofacial prosthodontics fabrication techniques, where a facial moulage and patient cooperation may be difficult.
