This contribution gives basic information about the mechanical behavior of the facial part of the human skull cranium, i.e., the splanchnocranium, associated with external loads and injuries caused mainly by brachial violence.

Commercial purity titanium grade 4 plates (50 × 20 × 0.1 mm) were tested to obtain their electrochemical and other technological properties.

- The paper examines the biomechanics of locking cortical bone screws in angularly stable plates used in treating bone fractures.
- Key issues arise during the removal of titanium-alloy implants, particularly with the stripping of the screw head's internal hexagon, which affects efficient extraction.
- Experimental findings indicate that screws with Torx type heads are superior to other designs in terms of reduced stress and strain, leading to a recommendation for all manufacturers to adopt this head type.
The paper addresses laboratory preparation and antibacterial activity testing of kaolinite/nanoTiO2 composite in respect of the daylight irradiation time. Kaolinite/nanoTiO2 composites with 20 and 40 wt% of TiO2 were laboratory prepared, dried at 105 °C and calcined at 600 °C. The calcination caused transformation of kaolinite to metakaolinite and origination of the metakaolinite/nanoTiO2 composite.
