Splintless surgery using patient-specific osteosynthesis in Le Fort I osteotomies: a randomized controlled multi-centre trialThe accuracy of orthognathic surgery has improved with three-dimensional virtual planning. The translation of the planning to the surgical result is reported to vary by >2mm. The aim of this randomized controlled multi-centre trial was to determine whether the use of splintless patient-specific osteosynthesis can improve the accuracy of maxillary translation. Patients requiring a Le Fort I osteotomy were included in the trial. The intervention- Can implants move in bone? A longitudinal in‐vivo micro CT analysis of implants under constant forces in rat vertebraeAbstract Objectives Whereas stationary stability of implants has been postulated for decades, recent studies suggested a phenomenon termed implant migration. This describes a change in position of implants as a reaction to applied forces. The present study aims at employing image registration of in‐vivo micro CT scans from different time points, and to assess (i) if migration of continuously loaded implants is possible and (ii) migration corr

- Patterns of facial fractures in childrenMorbidity and mortality among children is usually the result of trauma. Because a child’s face is retruded relative to the protecting skull, has a thicker layer of adipose tissue, more elastic bones, flexible sutures lines, the presence of tooth buds within the jaws, and the lack of pneumatisation of the sinuses, the facial bones fracture less commonly than in adults. Our aim was to assess the patterns of such fractures in children who presented
- Flaplessly placed 2.4-mm mini-implants for maxillary overdentures: a prospective multicentre clinical cohort studyStudies on flaplessly placed, one-piece mini dental implants (MDIs) supporting overdentures in the maxilla are scarce. This prospective multicenter cohort study evaluated the outcomes (over 2 years) of five to six MDIs placed in the maxilla for overdentures. Study patients were ≥50 years old, with an edentulous maxilla and dentate/fixed prosthesis in the mandible. Dentures were provisionalized with the final connection at 6 months. Implant/prosth
- Surgically assisted rapid maxillary expansion: a systematic review of complicationsA systematic review of the literature on the complications of surgically assisted maxillary expansion (SARME) was performed. The search strategy was based on the PRISMA guidelines. The PubMed, SCOPUS, and Cochrane Library databases were searched. Data were extracted from the full texts after screening of the abstracts and titles. Human clinical studies encompassing ‘maxillary expansion’, ‘palatal expansion’, ‘SARME’, or ‘SARPE’ and that reported

- Is vitamin D deficiency a risk factor for recurrent aphthous stomatitis? A systematic review and meta‐analysisAbstract Objectives A few studies have associated vitamin D deficiency with the occurrence of recurrent aphthous stomatitis (RAS). Hence, the aim of the present systematic review and meta‐analysis is to explore such a potential association. Methods A comprehensive search of PubMed, Scopus, and Web of Science databases was conducted in June 2019.The inclusion criteria were: 1) observational studies that assessed the relationship between

- Re: why do airline cockpits differ from operating theatres? Re: lead article: what has an Airbus A380 Captain got to do with OMFS? Lessons from aviation to improve patient safetyWe thank Uppal and Shikha for their complimentary letter about our recent article on applying important safety lessons learned from aviation to our specialty,1 and for allowing us to respond. Anything that helps to raise awareness about human factors (HF) for colleagues has to be good for both patient safety as well as improving team work.
- Postoperative complications after removal of pleomorphic adenoma from the parotid gland: A long-term follow up of 297 patients from 2002 to 2016 and a review of publicationsPleomorphic adenomas are rounded, lumpy, capsulated lesions that are more common in women. They are typically benign, but can be associated with malignancy in a minority of cases (such as carcinoma ex pleomorphic adenoma), between 3% - 12% of the time, according to available data. The purpose of our study was to evaluate clinical outcomes in patients with benign parotid gland tumours after extracapsular dissection (ECD) or superficial parotidecto
- Custom-made drill guides to access impacted mandibular premolarsThree-dimensional (stereolithographic) printing and patient-specific cutting guides have been used extensively in oral and maxillofacial surgery, particularly in orthognathic and reconstructive procedures.
