Accuracy of dental implant placement with CAD-CAM 3D printed and conventional thermoplastic surgical pilot guides: A clinical comparative trial.

Statement Of Problem: Dental implant placement is routinely guided by using 2-dimensional radiographs and thermoplastic surgical guides (CTGs), which may lack accuracy. Three-dimensionally (3D) printed surgical guides (3DGs) have been recommended to improve accuracy. However, they require additional training on specific technology.

Multi-Scale Characterization of Conventional and Immediate Dental Implant Systems.

We hypothesized that the different post-implantation healing stages between the conventional and immediate implantations produce different amounts and tissue composition of the peri-implant bone. Thus, the objective of the current study was to examine whether the stability of dental implant systems is associated with characteristics of the interfacial bone area at different post-implanation healing periods. Mandibular molars were extracted from each beagle dog.

Pseudomonas aeruginosa faces a fitness trade-off between mucosal colonization and antibiotic tolerance during airway infection.

Pseudomonas aeruginosa frequently causes antibiotic-recalcitrant pneumonia, but the mechanisms driving its adaptation during human infections remain unclear. To reveal the selective pressures and adaptation strategies at the mucosal surface, here we investigated P. aeruginosa growth and antibiotic tolerance in tissue-engineered airways by transposon insertion sequencing (Tn-seq).

Effects of extraoral storage time on autologous gingival graft early healing: A split-mouth randomized study.

Aims: Despite the established use of palatal tissue grafts for mucogingival procedures, there are no studies on the effect of extraoral storage time on graft outcomes. This prospective split-mouth randomized experimental clinical trial aimed to assess whether gingival graft extraoral storage time affects graft healing.

Methods: Standardized grafts were harvested from the palate and stored extraorally for 2 (Control) or 40 (Test) minutes before being placed at recipient beds.
