Reactive Oxygen Species-Responsive Pillararene-Embedded Covalent Organic Frameworks with Amplified Antimicrobial Photodynamic Therapy for the Targeted Elimination of Periodontitis Pathogens.

Reactive oxygen species (ROS)-responsive drug delivery systems possess immense potential for targeted delivery and controlled release of therapeutics. However, the rapid responsiveness to ROS and sustained release of antibacterial drugs are often limited by the challenging microenvironment of periodontitis. Integrating ROS-responsive drug delivery systems with photocatalytic technologies presents a strategic approach to overcome these limitations.

Flapless immediate implant placement into fresh molar extraction socket using platelet-rich fibrin: A case report.

Background: There are some challenges concerning immediate implant placement in the molar region. Platelet-rich fibrin (PRF), an autologous biomaterial, has been used widely for periodontal intra-bony defects, sinus augmentation, socket preservation, and gingival recession. However, the literature remains scarce for reports on immediate implants with PRF, particularly in the case of fresh molar extraction socket.

Minimally invasive endoscopic maxillary sinus lifting and immediate implant placement: A case report.

Background: This case report discusses a modified approach for maxillary sinus augmentation, in which platelet-rich fibrin, endoscope, simultaneous implant placement, and sinus floor elevation (PESS) were applied for a maxillary sinus floor lift in a 40-year-old patient.

Case Summary: A 40-year-old woman suffered missing upper right first molar. Implant stability quotient and cone-beam computed tomography (CBCT) were used to evaluate the diagnosis.
