Abstract Background To compare the accuracy of dental implant placement using a novel robotic system (THETA) and dynamic navigation (Yizhimei) by vitro model experiment. Methods 10 partially edentulous jaws models were included in this study, 20 sites randomly assigned into two groups: group group. implants placed defects according to each manufacturer’s protocol respectively. The platform, apex angle deviations measured fusion preoperative design actual postoperative cone-beam computed...
Robot-assisted implant surgery has emerged as a novel digital technology, and the accuracy need further assessment.
This clinical retrospective study aimed to compare the deviations in single-tooth implant placement using novel semi-autonomous robotic-assisted surgery system (sa-RASS) and dynamic navigation (DNS) methods. A analysis of medical records from January December 2023 was conducted implantation accuracy sa-RASS DNS partially edentulous patients cone-beam computed tomography. Platform, apex, angular were measured analyzed. The Kolmogorov-Smirnov test used check data distribution, along with...
The fracture of a Morse tapered abutment connection in an osseointegrated implant is one the most serious mechanical complications, and it extremely hard to deal with this complication clinical practice.The aim study was explore cumulative complications focus on platform switching taper system after loading, perform retrospective, approximately 1- 9-year follow-up identify predisposing factors.A total 495 patients 945 fitted implants were enrolled from January 2012 2020. data abutment,...
This study aimed to evaluate the accuracy of dental implant placement at single-tooth sites using a novel semi-autonomous robotic-assisted surgery system (sa-RASS).
The combination of a prosthetic index with Morse taper connection was developed, the purpose making procedures more precise. However, presence may compromise mechanical performance abutment. aim this study is to evaluate effect on stress distribution in implant-abutment-screw system and peri-implant bone by using 3D finite element methodology.Two commercial dental implant systems different implant-abutment connections were used: platform switching (MT-PS) internal hex matching (IH-PM)...
Regeneration of soft tissues, especially those requiring complex vascularization, is a major challenge in the field tissue engineering. The current types engineering scaffolds include sponges, electric spinning silk, hydrogels, and 3D printed biomaterials. Among them, hydrogels have unique property mimicking extracellular matrix (ECM), which can provide relatively stable microenvironment for cellular activities facilitate cell adhesion, proliferation, differentiation; thus, become promising...
This study evaluated the use of bone ring technique with xenogeneic grafts in treating horizontal alveolar defects. In total, 11 patients need augmentation treatment before implant placement were included this retrospective study. All received simultaneous surgery and grafts. We postoperative efficacy using radiographical clinical parameters. Survival rates implants 100%. Cone-beam computed tomography revealed that graft had significantly sufficient below neck platform to 0 mm, 1 2 3 mm. It...
Abstract This study aimed to investigate the effect and mechanism of 2α, 3α, 24‐thrihydroxyurs‐12‐en‐24‐ursolic acid (TEOA) alone or in combination with cisplatin on oral cancer. TEOA, a pentacyclic triterpenoid compound isolated from roots Actinidia eriantha , has demonstrated antitumor activity preclinical experiments. However, its role cancer remains poorly understood. Our findings revealed that low concentration TEOA did not exhibit significant cytotoxicity against squamous cell...
The survival rate, marginal bone loss and soft tissue health of the Ankylos implants balanced base abutments in all-on-four or six implant restoration edentulous terminal dentition patients has not been reported clinical research.This retrospective study aimed to evaluate after 1-8 years follow-up.A was conducted based on medical records 33 who received treatments from April 2014 May 2020. Four radiographic examinations [immediate postoperative (T0), definitive restorations (T1), 1-3...
An odontogenic keratocyst (OKC) is a common oral cyst arising from the epithelium, which has characteristics of tumor. Previous studies have demonstrated that M2-polarized macrophages and angiogenesis important roles in progression OKCs. As transforming growth factor (TGF)-β1 developmental processes, early indicated TGF-β1 upregulated OKCs, present study aimed to investigate expression levels as first step. Flow cytometric analysis suggested induced M2-polarization dose-dependent manner....
Abstract Extreme bleeding can make therapy challenging or even fatal. Even though several commercial homeostatic medicines have favorable clinical results, there is still a desire to discover materials that are effective, bio-safe, inexpensive, and simple produce. In this study, regulated uniformly sized chitosan microspheres (CSM) were fabricated using process assessed as hemostatic agents. addition, the diameter criteria for optimal effects evaluated. Precipitation coaxial airflow shear...
Objective To invesigate the therapeutic effect of anterior subapical osteotomy combined with postoperative orthodontic treatment for bimaxillary protrusion based on surgery-first approach(SFA). Methods From April 2015 to 2016, 22 adult patients were treated without peroperative treatment. Digital computer-aided technology was used preoperative design and dental model simulation surgery. Then occlusal guide plate made intraoperative built-up temporary occlusion. Two weeks after...
Abstract Objectives : This study evaluated the use of bone ring technique with xenogeneic grafts in treating horizontal alveolar defects. Material and methods: In total, 11 patients need augmentation treatment before implant placement were included this retrospective study. All received simultaneous surgery grafts. We postoperative efficacy using radiographical clinical parameters. Results Survival rates implants 100%. Cone-beam computed tomography revealed that graft had significantly...
Abstract Background The danger zone (DZ) commonly refers to the area of mesial roots in mandibular molars, which is more vulnerable perforations cases over-instrumentation. Midroot may lead a dubious prognosis and ultimately tooth extraction. In clinical practice, identifying preventing perforation are extremely crucial. However, there no articles that systematically summarize relevant studies since concept was first introduced 1980s. Case presentation This report describes failed root canal...
Objective The purpose of this study was to explore the surgery-first approach in sequential combined orthodontic-orthognathic treatment shorten total duration and improve clinical outcome. Methods This included 185 patients with Angle classⅢ malocclusion. The were divided into 3 different types according cephalometry analyses facial features. ①Type Ⅰ: mandibular prognathism or asymmetry prognathism; ②Type Ⅱ: maxillary retrusion; ③ Type Ⅲ: mild Angle′s Class Ⅲ malocclusion, cross bite...
