Pre-extraction alveolar buccal bone overbuilding: a preclinical investigation.
Oral Maxillofac Surg
December 2024
Department of Oral Implantology, Osaka Dental University, 8-1 Kuzuhahanazonocho, Hirakata, 573-1121, Osaka, Japan.
Background: The pre-extraction overbuilding procedure was designed aiming to mitigate buccal bone resorption following tooth extraction. The objective of this study was to compare the efficacy of pre-extraction and juxta-extraction buccal overbuilding treatments in preserving buccal bone volume following tooth extraction.
Material And Methods: At the test sites (pre-extraction sites), an alveolar crest overbuilding was performed on the buccal aspect of the distal root of the fourth premolar using a xenograft covered with a collagen membrane.
Changes in the Periodontal Gap After Long-Term Tooth Movement into Augmented Critical-Sized Defects in the Jaws of Beagle Dogs.

Extensive and closely coordinated remodeling processes take place in the periodontal ligament (PDL) and the adjacent bone during orthodontic tooth movement. In complex orthodontic cases, it is necessary to move teeth into an augmented bony defect, for example, in patients with cleft lip, alveolus, and palate. The important role of the PDL during tooth movement is well accepted but not fully understood.

Introduction: Tooth extraction initiates a cascade of homeostatic and structural modifications within the periodontal tissues, culminating in alveolar ridge resorption. To prevent ridge resorption following extraction and facilitate successful placement of an implant-supported prosthesis, alveolar ridge preservation was performed.
Methods: In this study, the biocompatibility of a nanocomposite consisting of self-assembling peptide nanofibers (organic phase) and tri-calcium phosphate-nano hydroxyapatite (mineral phase), was evaluated in rabbits.
FAM96B negatively regulates FOSL1 to modulate the osteogenic differentiation and regeneration of periodontal ligament stem cells via ferroptosis.

Department of Orthodontics, Peking University School and Hospital of Stomatology, Beijing, 100081, China.
Background: Periodontal ligament stem cell (PDLSC)-based therapy is one of the methods to assist bone regeneration. Understanding the functional regulation of PDLSCs and the mechanisms involved is a crucial issue in bone regeneration. This study aimed to explore the roles of the family with sequence similarity 96 member B (FAM96B) in the functional regulation of PDLSCs.

Replacing a hopeless molar with a dental implant is one of the most common treatment modalities in implant dentistry. However, immediate implant post-extraction in the posterior region requires managing the bone gap and ensuring primary closure of the socket. To address this anatomical consideration, several authors have proposed using a custom abutment to seal the socket after immediate implant placement, maintain soft tissue contour, and stabilize the surrounding tissues.
