OBJECTIVE To evaluate whether patients who had received early class III protraction facemask treatment were less likely to need orthognathic surgery compared with untreated controls. This paper is a 6-year follow-up of a previous clinical trial. DESIGN Multi-centre 2-arm parallel randomized controlled trial. SETTING Eight United Kingdom hospital orthodontic departments. PARTICIPANTS Seven...

BACKGROUND Osteoprotegerin (OPG) is considered to be the cytokine that plays an important role in the healing process. OPG regulates bone cell biology, osteoblast-osteoclast, bone-immune cross-talk and maintenance of bone mass. It plays an important role in the development, induction, and repair of bone. Orthognathic surgery as multiples segmental osteotomies has been taken as a model surgery t...

Introduction: The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratoryepitheliumin the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery....

Orthognathic surgery corrects a wide range of minor and major facial and jaw irregularities. This surgery will improve the patients’ ability to chew, speak and breathe. In many cases, a better appearance will also result. With the recent advances in virtual reality (VR) and three-dimensional (3D) medical imaging technology, orthognathic surgery simulations typically requires costly volumetric d...

Many medical departments use several multi-disciplinary technologies to support the planning of the surgery. For complex operations a collaboration between different experts can improve the success rate, but the tools are mostly on-premises software and limit the good cooperation. In this case, the orthognathic and dental surgery uses 3D and CT scans to plan the surgery beforehand by making use...

The main purpose of this study was to investigate the impact of maxillary advancement on speech resonance in subjects with cleft lip and palate. The study sample was composed of 42 subjects aged 16 to 41 years old with operated cleft palate ± lip submitted to maxillary advancement. Resonance was evaluated before and 3 to 12 months after surgery by perceptual analysis and graduated from absent t...

background: the cytokines have a major role in the inflammatory response to surgery and trauma. they have local effects of mediating and maintaining the inflammatory response to tissue injury, and also initiate some of the systemic changes which occur. il-6 is one of the above mentioned cytokines, but it is not clear whether the duration of trauma or surgery has some effect on il-6 level, so th...

The “Surgery-first” approach, defined as a team approach between surgeons and orthodontists for orthognathic surgery without preoperative orthodontic treatment, is aimed at dental decompensation. first provides an alternative treatment protocol in cases. conventional ortho-surgical includes orthodontics which requires 7 to 20 months will result into temporary worsening of facial profile. Surger...
