Influence of different polymeric materials of implant and attachment on stress distribution in implant-supported overdentures: a three-dimensional finite element study.
BMC Oral Health
January 2025
Department of Prosthetic Dentistry, Biomaterials Division, Faculty of Dentistry, King Salman International University, El Tur, South Sinai, Egypt.
Purpose: Investigating high performance thermoplastic polymers as substitutes to titanium alloy, in fabrication of implants and attachments to support mandibular overdenture, aiming to overcome stress shielding effect of titanium alloy implants. AIM OF STUDY: Assessment of stress distribution in polymeric prosthetic components and bone around polymeric implants, in case of implant-supported mandibular overdenture.
Materials And Methods: 3D finite element model was established for mandibular overdenture, supported bilaterally by two implants at canine region, and retained by two ball attachments.
The effect of autologous demineralized dentin matrix on postoperative complications and wound healing following lower third molar surgery: A split-mouth randomized clinical trial.

Department of Oral Surgery, Faculty of Odonto-Stomatology, University of Medicine and Pharmacy at Ho Chi Minh City, Ho Chi Minh City, Viet Nam.
Background/purpose: Autologous dentin materials are among the most promising bone substitutes for preventing osseous defects on the distal side of the lower second molar. This study aimed to investigate the effects of autologous demineralized dentin matrix on postoperative complications and wound healing after lower third molar surgery.
Materials And Methods: Thirteen patients with bilateral symmetrical lower third molars participated in this split-mouth randomized clinical trial.
Oyster Shell Powder/PCL Composite Scaffolds Loaded with Psoralen Nanospheres Promote Large Bone Defect Repair.

Research on bone substitutes for repairing bone defects has drawn increasing attention, and the efficacy of three-dimensional (3D) printed bioactive porous scaffolds for bone defect repair has been well documented. Our previous studies have shown that psoralen can promote osteogenesis by activating the Wnt/β-catenin and BMP/Smad signaling pathways and their crosstalk effects, and psoralen nanospheres have a good osteogenesis-promoting effect with low cytotoxicity. The Chinese medicine oyster shell powder, characterized by its porous structure, strong adsorption, and unique bioactivity, has potential in fracture-promoting repair materials.

Introduction: The primary objective of any implant system is to achieve firm fixation to the bone, which can be influenced by both biomechanical factors and biomaterial selection. An array of materials is used for the replacement of missing teeth through implantation. The appropriate selection of biomaterials directly influences the clinical success and longevity of implants.
