OBJECTIVES Loosening and loss rates of monocortical mini-implants are relatively high, therefore the following null hypothesis was tested: 'The local bone stress in mono and bicortically-anchored mini-implants is identical'. MATERIAL AND METHODS Anisotropic Finite Element Method (FEM) models of the mandibular bone, including teeth, periodontal ligaments, orthodontic braces, and mini-implants ...

The functional demand imposed on bone promotes changes in the spatial properties of osteocytes as well as in their extensions uniformly distributed throughout the mineralized surface. Once spatial deformation is established, osteocytes create the need for structural adaptations that result in bone formation and resorption that happen to meet the functional demands. The endosteum and the periost...

If a posterior tooth has been lost and is not restored immediately, the patient may subsequently experience a variety of problems. The adjacent teeth tend to tilt and rotate, and the opposing tooth may overerupt. Available options to restore occlusion include elective root canal treatment with invasive tooth reduction, surgical impaction or orthodontic therapy requiring extraoral headgear or fu...

ment can be particularly challenging in adult patients. Although many appliances have been proposed for maxillary molar distalization in such cases,1,2 they generally require some degree of patient compliance, and their de sign causes anchorage loss due to the incorporation of occlusal rests or bands on the premolars. The introduction of skeletal anchorage has radically changed orthodontists’ a...

AIM The purpose of this prospective cohort study was to assess the survival and success rates of palatal implants. MATERIAL AND METHODS Seventy patients (56 female, 14 male; age 25-6 +/- 10-8 years) receiving Orthosystem (Straumann AG, Basel, Switzerland) palatal implants from March 1999 to November 2006 were included. The indication was established according to the required anchorage for ort...

AIM To provide clinicians with useful information for immediate diagnosis and management of impacted maxillary incisors due to trauma. METHODS We present a case of post-traumatic impaction of a central right maxillary incisor in a young patient. The treatment plan consisted in the interceptive management (surgical and orthodontic), the valuation of the necessary space to move the impacted too...

Temporary Anchorage Devices have been the only means of providing absolute anchorage but complications causing soft and hard tissue damage requires well-formed cortical bone. Also, they are unable to tolerate torsional forces moments. For this reason, miniplates had come up with advantage more surface area difficult place as require flap surgery also removal post treatment. CTOR plates revoluti...

The purpose of this study was to develop a new method of releasing fluorine in a controlled manner for applications in the field of orthodontic Ti-based wire, namely the coating of fluorides on Ti. Thin films of two fluoride compounds, CaF(2) and MgF(2), were coated on Ti via the electron-beam evaporation method. The fluorine was released rapidly from the as-deposited MgF(2) coating within a sh...

INTRODUCTION Craniofacial orthodontics has been shown to be a critical component of the care of patients with craniofacial anomalies such as cleft lip and palate. Thus, the purpose of this study was to assess the perceptions and clinical experience in cleft and craniofacial care, of orthodontic residents in Nigeria. METHODOLOGY Questionnaires were sent out to orthodontic residents in the six ...
