Mechanical Performance of Extensive Restorations Made with Short Fiber-Reinforced Composites without Coverage: A Systematic Review of In Vitro Studies.

In recent years, composite resin materials have been the most frequently used materials for direct restorations of posterior teeth. These materials have some clinically relevant limitations due to their lack of fracture toughness, especially when used in larger cavities with high volume factors or when utilized as direct or indirect overlays or crown restorations. Recently, short-fiber-reinforced composite materials have been used in bi-structure restorations as a dentine substituting material due to their superior mechanical properties; however, there is no scientific consensus as to whether they can be used as full restorations.

Fatigue Resistance of Dissected Lower First Molars Restored with Direct Fiber-Reinforced Bridges-An In Vitro Pilot Study.

The aim of this research was to evaluate the mechanical impact of utilizing different fiber-reinforced composite (FRC) systems to reinforce inlay-retained bridges in dissected lower molars with different levels of periodontal support. A total of 24 lower first molars and 24 lower second premolars were included in this study. The distal canal of all molars received endodontic treatment.

[Application of digital technique in the diagnosis of periodontal diseases and in surgical planning].

Imaging techniques play a primary role in the assessment of the severity of periodontal diseases. However, X-rays are often insufficient to reveal their real nature and extent. One of the most difficult questions to decide is the exact shape and extent of the bony defect, as it undoubtedly poses a major impact on our choice of therapy.

The biomechanical effect of root amputation and degree of furcation involvement on intracoronally splinted upper molar teeth - An in vitro study.

Objectives: The aim of this study was to evaluate the effect of the amount of periodontal support and the presence or absence of root amputation on the fracture resistance of intracoronally splinted maxillary molar teeth.

Materials And Methods: 48 extracted human upper first molars and 48 s premolars were included in the study. All teeth underwent standard mesio-occluso-distal (MOD) (molars) and standard occluso-distal (OD) (premolars) cavity preparation.
