TL;DR: It is demonstrated that zirconia implants with modified surfaces result in an osseointegration which is comparable with that of titanium implants, which have a roughened surface but otherwise similar implant geometries.

TL;DR: The use of autogenous bone is advantageous if a prosthetic rehabilitation (with functional loading) is expected within 9 months and in other cases the use of anorganic deproteinized bovine bone in combination with autogenousBone seems to be preferable.

TL;DR: The results of this study indicate similar osseointegration of zirconia and titanium implants at the ultrastructural level.

TL;DR: Zirconia improves cell proliferation significantly during the first days of culture, but it does not improve attachment and adhesion strength, and both materials do not differ with respect to protein synthesis or ultrastructural appearance of osteoblasts.

TL;DR: Inferior condylar neck fractures benefit from ORIF by an intraoral approach whereas in high condylars neck fractures the retromandibular/transparotid approach shows the best results.
