Apt‐19s‐Functionalized 3D‐Printed Mesoporous Bioactive Glass Scaffold Promotes BMSC Recruitment in Bone Regeneration via SDF‐1α/CXCR4 Axis and MAPK Signaling

Zeying Wang, An Lao, Xingtai Huang, Yongsheng Zhou, more

Advanced Functional Materials > 34 > 27 > n/a - n/a

Directional migration and differentiation of stem cells in situ are two essential processes for tissue regeneration. However, transplanted scaffold itself lacks sufficient ability to induce stem cell recruitment. As an artificial synthesized nucleic acid, aptamer 19s (Apt‐19s), with high cost‐effectiveness and bioactivity, demonstrates a robust capacity for specific binding and recruitment of mesenchymal...

ScRNA‐seq links dental fibroblasts heterogeneity with mechanoresponsiveness

Hongyuan Xu, Qinggang Dai, Xinyu Wang, Anting Jin, more

Journal of Periodontal Research > 58 > 4 > 800 - 812

Background and objective Periodontal ligament (PDL) and dental pulp (DP) share a common origin but have distinct biological and mechanical functions. To what extent the mechanoresponsive property of PDL can be attributed to its unique transcriptional profiles of cellular heterogeneity is unclear. This study aims to decipher cellular heterogeneity and distinct mechanoresponsive characteristics of...

Do Open Reduction and Internal Fixation With Articular Disc Anatomical Reduction and Rigid Anchorage Manifest a Promising Prospect in the Treatment of Intracapsular Fractures?

Bo-Lei Cai, Rong Ren, Hong-Bo Yu, Peng-Chao Liu, more

Journal of Oral and Maxillofacial Surgery > 2018 > 76 > 5 > 1026-1035

In response to the increased attention to soft tissue reduction in the treatment of intracapsular condylar fractures (ICFs), a modified open reduction technique is proposed and its functional and radiographic outcomes were evaluated in this study.This is a retrospective case series study of patients with all ICF types that were treated with open reduction and internal fixation (ORIF) with articular...

Accuracy of maxillary repositioning by computer-aided orthognathic surgery in patients with normal temporomandibular joints

Xiaozhen Lin, Biao Li, Xudong Wang, Steve G.F. Shen

British Journal of Oral and Maxillofacial Surgery > 2017 > 55 > 5 > 504-509

Our aim was to assess the accuracy of computer-aided orthognathic surgery for maxillary repositioning in 15 patients with mandibular hyperplasia and normal temporomandibular joints (TMJ). We aligned preoperative and postoperative virtual skulls at the cranium using surface superimposition then recorded and calibrated three 3-dimensional coordinates (maxillary dental landmarks U0, 6R, and 6L) on the...

Accelerated Orthodontic Tooth Movement Following Le Fort I Osteotomy in a Rodent Model

Hao Yuan, Xiaofang Zhu, Jingting Lu, Jiewen Dai, more

Journal of Oral and Maxillofacial Surgery > 2014 > 72 > 4 > 764-772

In surgery-first accelerated orthognathic surgery, the clinical phenomenon of accelerated orthodontic tooth movement after osteotomy is a benefit compared with the conventional approach. However, because much of the literature on this phenomenon is based on empirical evidence and case reports, experimental animal-based studies are needed to verify and quantify this acceleration effect. The purpose...

Navigation-Guided Lateral Gap Arthroplasty as the Treatment of Temporomandibular Joint Ankylosis

Haijun Gui, Jinyang Wu, Steve G.F. Shen, Joy S. Bautista, more

Journal of Oral and Maxillofacial Surgery > 2014 > 72 > 1 > 128-138

This article presents a novel method of navigation-guided lateral gap arthroplasty (LGA) in the treatment of temporomandibular joint ankylosis (TMJA).Six patients with unilateral TMJA from 2007 through 2011 were included in this study. Presurgical planning was performed to determine the amount and extent of ankylosed bone to be resected using the simulation platform. Minimum follow-up was 6 months...

Real-time image-guided recontouring in the management of craniofacial fibrous dysplasia

Haijun Gui, ShiLei Zhang, Steve G.F. Shen, Xudong Wang, more

Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology > 2013 > 116 > 6 > 680-685

This report presents our experience using computer-aided recontouring in the surgical management of complex craniofacial fibrous dysplasia with the use of a navigation system developed by the authors.A total of 21 patients (9 men and 12 women) with craniofacial fibrous dysplasia and mean age of 23 years (range, 17-32 years) were included in this study from 2007 to 2012. By creating a mirror image...

Error analysis of a CAD/CAM method for unidirectional mandibular distraction osteogenesis in the treatment of hemifacial microsomia

Hao Sun, Biao Li, Zeliang Zhao, Lei Zhang, more

British Journal of Oral & Maxillofacial Surgery > 2013 > 51 > 8 > 892-897

Our aim was to investigate the errors in a computer-aided design and manufacture (CAD/CAM) method of unidirectional mandibular distraction osteogenesis. Six patients with hemifacial microsomia were selected, and studied on computed tomographic (CT) scans taken at 3 time intervals: preoperatively, at the end of the latent period, and at the end of consolidation. The plan for mandibular distraction...

A novel method of computer aided orthognathic surgery using individual CAD/CAM templates: a combination of osteotomy and repositioning guides

Biao Li, Lei Zhang, Hao Sun, Jianbing Yuan, more

British Journal of Oral & Maxillofacial Surgery > 2013 > 51 > 8 > e239-e244

The maxilla is usually positioned during orthognathic surgery using surgical splints, which has many limitations. In this preliminary study we present a new computer-aided design and manufacture (CAD/CAM) template to guide the osteotomy and the repositioning, and illustrate its feasibility and validity. Six patients with dental maxillofacial deformities were studied. The design of the templates was...

Image-Guided Surgical Navigation for Removal of Foreign Bodies in the Deep Maxillofacial Region

Haijun Gui, Huawei Yang, Steve G.F. Shen, Bing Xu, more

Journal of Oral and Maxillofacial Surgery > 2013 > 71 > 9 > 1563-1571

Most trauma surgeons encounter numerous penetrating injuries. Some foreign bodies can cause pain, infection, and discomfort to the patient. Serious functional disorders also are likely to occur. Foreign bodies in critical areas must be removed. This report describes the use of image-guided technology for the removal of foreign bodies deep in the maxillofacial region.From 2008 through 2011, 5 patients...

Implicit Association Test: A possible tool for screening patients for orthognathic surgery

Dedong Yu, Bing Fang, Fang Wang, Xudong Wang, more

Medical Hypotheses > 2013 > 81 > 2 > 309-310

In orthognathic surgery, many serious medical disputes and postsurgical dissatisfactions are not caused by the doctors’ reasons, but due to the patients’ psychological problems. These adverse events obsess not only surgeons, but also patients to a great extent. An effective method is expected to screen patients for orthognathic surgery. So far, most selecting approaches in orthognathic surgery are...

3D soft tissue planning and prediction

James Xia, Nabil Samman, Richie W.K. Yeung, Dongfeng Wang, more

International Journal of Oral & Maxillofacial Surgery > 2000 > 29 > 4 > 250-258

The purpose of this paper is to report a new technique for three-dimensional facial soft-tissue-change prediction after simulated orthognathic surgical planning. A scheme for soft tissue deformation, “Computer-assisted three-dimensional virtual reality soft tissue planning and prediction for orthognathic surgery (CASP)”, is presented. The surgical planning was based on three-dimensional reconstructed...
