Objectives: The aim of this study was to assess the effects of different orthodontic vertical loop height and design on its force characteristics at different amount of loop activation by means of finite element method (FEM) analysis. Materials andMethods: Four 3D FEM models were designed of double vertical open loop (DVOL) and double vertical helical open loop (DVHOL) each of them in two heigh...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
abstract the attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. this clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. the clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements, ge...
Double or fusion of the teeth is a primary developmental anomaly union of two independently developing primary or permanent teeth. The tooth fusion may contribute to various significant problems such as crowding, caries and periodontal diseases and they may be associated with anomalies in the succeeding permanent dentition which necessitate careful examination & proper treatment planning becaus...
The incidence of nonsyndromic supernumerary premolars is rare. Supernumerary premolars are likely to undergo pathological changes. The most commonly encountered complications with these teeth are dentigerous cyst and root resorption of the adjacent tooth. This paper is about impacted double fused supernumerary premolars in the right mandiblular body associated with an impacted first premolar in...
: Acromial stress fractures are rare and have not been highlighted as a potential complication of wheelchair use. We report the case of a 22-year old female wheelchair bound patient with Charcot-Marie-Tooth disease who presented with a four-year history of shoulder pain which impaired mobility and quality of life. Plain radiographs showed a cortical irregularity of the acromion but no double-de...
The tooth is an ectodermal organ that arises from a tooth germ under the regulation of reciprocal epithelial-mesenchymal interactions. Tooth morphogenesis occurs in the tooth-forming field as a result of reaction-diffusion waves of specific gene expression patterns. Here, we developed a novel mechanical ligation method for splitting tooth germs to artificially regulate the molecules that contro...
Erratum to: An exploratory randomised double-blind and placebo-controlled phase 2 study of a combination of baclofen, naltrexone and sorbitol (PXT3003) in patients with Charcot-Marie-Tooth disease type 1A Shahram Attarian, Jean-Michel Vallat, Laurent Magy, Benoît Funalot, Pierre-Marie Gonnaud, Arnaud Lacour, Yann Péréon, Odile Dubourg, Jean Pouget, Joëlle Micallef, Jérôme Franques, Marie-Noëlle...
Oronasal fistula is a relatively common complication associated with maxillary canine tooth extraction, problematic healing of maxillectomy, and repair of secondary cleft palate in small animals. Regardless of the clinical scenario associated with oronasal fistula, therapy requires surgical treatment. Principles for surgical repair of oronasal fistula include development of mucosal flaps with e...
Talon cusp is a dental anomaly also known as an eagle's talon. It is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. The exact etiology is unknown. The inci-dence of talon cusp is less than 6%. Commonly involved teeth are maxillary incisors, usually unilateral but in some instanc-es bilateral. The classical ...
