The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Filtration Bypassing Retaining Hydraulic Structures
Наука и техника, 2020 Concrete dams that are part of river waterworks are integrated with earthworks or with banks using coastal abutments. If the soil of cost or earthen dam is permeable, then in the zone of contiguity water filtration occurs around the coastal abutment ...

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Cement-retained and Screw-retained Implant-supported Prostheses in Treatment of Dental Arch Defects
Česká Stomatologie a Praktické Zubní Lékařství, 2007 Fixed dentures could be connected to implants by abutments, through tightening of small screws or cementation. Another option is the direct screw connection without abutments.

Restoration of human tooth enamel
BMEMat, EarlyView.Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Is the re-use of sterilized implant abutments safe enough? (Implant abutment safety)
Medicina Oral Patología Oral y Cirugia Bucal, 2019 The reuse of implant healing abutments is common in dental practice. Effective elimination of bacteria and viruses is accomplished by conventional sterilization. The aim of this work was to explore the eventual survival of microorganisms on sterilized healing abutments and to rule out the presence of transmissible organic material after standard ...

Crestal approach for repair of oroantral bone defects and subsequent implant placement
Clinical Advances in Periodontics, EarlyView.Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.

Clinical Advances in Periodontics, EarlyView.Abstract Background Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non‐carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics.
