Aim: To evaluate fracture resistance and vertical marginal gap in permanent molars restored with nano-ceramic hybrid CAD/CAM material (Grandio blocs) and reinforced composite CAD/CAM material (BRILLIANT Crios Block) compared to the IPS e.max ceramic Onlay restoration.
So, the current study aims at comparing a novel technique for the inferior alveolar nerve block (IANB) depending on extraoral landmarks with the conventional technique. The study group patients received IANB employing the novel technique.
Aim: This clinical study evaluated and compared pain perception of the inferior alveolar nerve block and buccal infiltration techniques in children using Conventional syringe and STA Wand® device.
Objective: to evaluate microshear bond strength of CAD/CAM composite block and hybrid ceramic block repaired by direct resin composite restoration with and without surface treatment.
Therefore, the current study aimed at introducing a novel intraoral technique for the inferior alveolar nerve block that entirely depended on extraoral landmarks and to compare it with the conventional technique.
The detected mode of failure was an oblique fracture extending from the lingual surface to the labial surface at or just below the insertion of the tooth in the epoxy resin block.
In order to solve Class II division 1 malocclusion in developing patients with a retrognathic mandible, this study was planned to evaluate the dental, skeletal, and soft tissue implications of employing the twin block appliance.
Aim: The aim of this study is to evaluate the efficacy of an interocclusal acrylic bite block as a preventative and conservative tool to prevent or minimize post radiation trismus in an effort to improve the quality of life of irradiated patients.
Preparation of the experimental model were mounted in epoxy resin blocks (Transparent self-curing polyester resin, Acrostone- cold cure cross-linked, Egypt) using specially designed cylindrical teflon mold for holding the epoxy resin and tooth inside. Accurate centralization of the tooth in the resin block was achieved using
Cyclic fatigue testing utilized a specialized block simulating dental canals, following Grande et al.'s prescribed design. Lubricating oil flooded the artificial canals, and files were tested at specified RPM and torque until breakage, with recorded breakage times.
