Next-generation sequencing analysis of bacterial species present in the sequestrum of medication-related osteonecrosis of the jaw patients.

Objective: Antiresorptives cases of adverse reactions to highly effective drugs used to treat skeletal-related events that occur during treatment of osteoporosis or malignancy have been reported in the jaw. To date, there is no clear pathophysiology for medication-related osteonecrosis of the jaw (MRONJ), but the role of inflammation or infection has been proposed as one of several possible pathogenesis theories. This study was designed to investigate the role of infection in the pathogenesis of MRONJ by analyzing the microbial communities observed in the bone samples from MRONJ patients.

Recommendations for mitochondria transfer and transplantation nomenclature and characterization.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Tapered Submerged Implants in an Augmented Posterior Maxilla After Oroantral Fistula Closure.

Dental implantation in the posterior maxilla is challenging due to anatomic proximity to the sinuses, relative bone quality, and pre-existing sinus diseases. An oroantral fistula (OAF) acts as a pathologic pathway of bacteria and can cause sinus infections and complicate dental implant management. Bony augmentation between the sinus floor mucosa and the oral mucosa at the OAF closure site is another critical consideration.

Long-term follow-up of posterior implant restorations showing under-occlusion: a superimposition analysis of dentition change.

Under-occlusion ('infraocclusion' as defined in the natural teeth) after implant restoration in the posterior area is commonly encountered in clinical practice; however, it has rarely been reported. Most importantly, the under-occlusion change mechanism remains unknown. The purpose of this case report was to analyze how the dentition of both arches changed in a patient, including teeth tilting, elongation and occlusal plane change with under-occlusion of the posterior implant restoration after long-term function.
