Abstract Existing surgical tissue adhesives on the market cannot meet desired demand for clinical operations due to their limited adhesivity or undesired cytotoxicity. A new bioadhesive is derived from skin secretion of Andrias davidianus (SSAD). This bioinspired SSAD has significantly stronger adhesion than fibrin glue and improved elasticity biocompatibility when compared cyanoacrylate both ex vivo in vivo. Additionally, SSAD‐based adhesive decreases wound healing time promotes...
Bone fusion of defect broken ends is the basis functional reconstruction critical maxillofacial segmental bone defects. However, currently available treatments do not easily achieve this goal. Therefore, study aimed to fabricate 3D-printing titanium grid scaffolds, which possess sufficient pores and basic biomechanical strength facilitate osteogenesis in order accomplish mandibular The clinical trial was approved supervised by Medical Ethics Committee Chinese PLA General Hospital on March...
Abstract Background The aim of this study is to conduct a comparative evaluation different designs clear aligners and examine the disparities between fixed appliances. Methods 3D digital models were created, consisting maxillary dentition without first premolars, maxilla, periodontal ligaments, attachments, micro-implant, printed lingual retractor, brackets, archwire aligner. involved creation five design for aligner anterior internal retraction one model appliance retraction, which...
Customized alveolar bone augmentation provides sufficient and precisely regenerated tissue for subsequent dental implant placement. Although some clinical cases have confirmed the successful use of patient-specific polyetheretherketone (PEEK) scaffolds, biomechanical property osteogenic performance PEEK scaffolds remain unclear. The objectives this study were (1) to evaluate space maintenance capacity customized (2) compare properties three-dimensionally printed titanium scaffolds. Both...
Tooth development is regulated by sequential and reciprocal epithelium-mesenchymal interactions their related molecular signaling pathways, such as bone morphogenetic proteins (BMPs). Among the 14 types of BMPs, BMP9 (also known growth differentiation factor 2) one most potent BMPs to induce osteogenic mesenchymal stem cells. The purpose this study was examine potential roles in tooth development. First, we detected expression pattern germ during postnatal development, found that widely...
Background: Full ceramic or metal custom-made root analogue implants (RAIs) are made by replicating the natural tooth geometry. However, it may lead to stress shielding of surrounding bone, and an RAI is unable easily achieve primary stability. Therefore, improve stability reduce shielding, porous structures proposed. The purpose this study was evaluate effect microstructures on biomechanical characteristics RAI. Methods: Porous bulk titanium cylinders conventional for in vivo tests were...
Subperiosteal implants represent an alternative implant approach for cases with severe bone atrophy. Although some successful clinical have been reported, the biomechanical stability of subperiosteal remains unclear, and more data are needed to confirm feasibility this approach. Therefore, study investigated characteristics based on histological observation, cases, finite element analysis. Finite analysis indicated that a lattice-like structure could better disperse stress underlying...
Vertical bone augmentation remains a significant challenge in implant dentistry and orofacial surgery, which is aimed at regenerating extraskeletal. This study conducts proof-of-concept investigation into the effects of additively manufactured bioceramic scaffolds featuring bioinspired 3D architectures (trabecular, open channel, layered) on vertical from perspectives osteogenesis biomechanics. The experimental scaffold design was categorized 4 Groups. Compression tests finite element...
To present the results of guided bone regeneration (GBR) with three-dimensional printing individualized titanium mesh (3D-PITM) applied to alveolar defects different Terheyden classifications and factors affecting osteogenic outcome.Fifty-nine patients, presenting 61 defect sites, were enrolled between 2018 2021. GBR+3D-PITM was obtained simultaneous or second stage implant placement. The complication rate, success rate grafting procedure survival documented. Bone gain, thickness...
Background Three‐dimensional (3D) printed models have been shown to be promising in surgical training rhinology. The objectives of this study were develop a set 3D‐printed including the pediatric and adult nasal cavity, postsurgical paranasal sinuses, assess face content validity endoscopic training. Methods computed tomography (CT) data patient without disorders an with septal deviation selected produce CT who underwent sinus surgery 4 months ago was chosen create model. After by our...
Individualized titanium mesh holds many advantages over conventional mesh. There are few reports in the literature about effect of pore size and thickness on mechanical properties This study is designed to develop an individualized using computer-assisted design additive manufacturing technology. will also explore different thicknesses sizes its through 3D FEA. According this study, increased when decreased (0.5 mm 0.3 mm). With increase diameter (3 5 mm), decreased. The has less influence...
To develop an in vivo model to simulate the complex internal environment of diabetic peri-implantitis (T2DM-PI) for a better understanding type 2 patients.Maxillary first molars were extracted Sprague-Dawley (SD) rats, and customized cone-shaped titanium implants installed extraction sites. Thereafter, uncovered abutments screwed into implants. A high-fat diet low-dose injection streptozotocin utilized induce T2DM. Finally, LPS was locally injected implant sulcus peri-implantitis.In present...
Abstract Objective Additively manufactured (3D-printed) titanium meshes have been adopted in the dental field as non-resorbable membranes for guided bone regeneration (GBR) surgery. However, according to previous studies, inaccuracies between planned and created volume contour are common, many reasons speculated affect its accuracy. The size of alveolar defect can significantly increase patient-specific mesh design surgical difficulty. Therefore, this study aimed analyze investigate effect...
Telescopic overdentures supported by the combination of natural teeth and implants have been thought a valuable treatment for severely compromised partially edentulous patients. But involves highly complex biomechanical problems. This study is to evaluate behaviors abutment with combined tooth-implant telescopic crown prostheses in mandible through 3D FEA. According this study, prosthetic option retained double crowns could protect their periodontal support tissues acting as rigid splint,...
Several different methods exist for reconstructing the mandibular body and ramus defect with use of a free vascularized fibula flap, but none have adequately addressed long-term mechanical stability osseointegration.
