Implant Placement Using the Bone Ring Technique With and Without Membrane Placement: A Preclinical 12-Month Study in Dogs.

The bone ring technique is applied for vertical augmentation, in which the dental implant and autogenous block bone graft are simultaneously inserted. We investigated the healing of bone around implants placed simultaneously using the bone ring technique with and without membrane placement after a 12-month healing period. Vertical bone defects were created on both sides of the mandible of Beagle dogs.

Pumping the Periosteum: A Feasibility Study.

Purpose: Gradual elevation of periosteum from the bone surface is known to promote the adaptation of soft tissues and the formation of hard tissues. The aim of our study was to estimate the benefit of periosteal distraction osteogenesis (PDO) on de novo bone formation in a rat model.

Materials And Methods: After device placement, animals were allowed for a latency period of 7 days.

CBCT imaging and histopathological characteristics of osteoradionecrosis and medication-related osteonecrosis of the jaw.

Purpose: The purpose of this study was to evaluate the cone-beam computed tomographic (CBCT) imaging and histopathological characteristics of osteoradionecrosis (ORN) and medication-related osteonecrosis of the jaw (MRONJ).

Materials And Methods: Ten surgical specimens from segmental mandibulectomy (3 ORN and 7 MRONJ) were analyzed using CBCT. The CBCT parameters were as follows: high-resolution mode (tube voltage, 90.

Comprehensive analysis and comparison of proteins in salivary exosomes of climacteric and adolescent females.

Currently, it is difficult to extract exosomes with stable physicochemical properties from saliva. Furthermore, due to inadequate availability of basic data, the application of salivary exosomes as a diagnostic material is limited. In this study, we aimed to investigate an easier method for extraction of exosomes from whole saliva and compared proteins in salivary exosomes derived from subjects of two age groups.
