Evaluation of the mechanical properties and surface topography of as-received, immersed and as-retrieved orthodontic archwires.

Background And Aims: This experimental study mainly aims at comparing the most important mechanical properties of the new orthodontic archwires, those immersed in fluorinated solution, the as-retrieved ones and the intra-oral used ones.

Methods: A total of 270 arch wires were tested, using tensile testing and three-point bending tests. The tested archwires were made of Stainless Steel, Nickel Titanium, Beta-Titanium and physiognomic covered Nickel Titanium.

The heterogeneity of craniofacial morphology in Prader-Willi patients.

Prader-Willi syndrome is a complex genetic disorder with narrow spectrum of facial phenotypic signs, which make the clinical diagnosis difficult in some cases. There are several reports describing the craniofacial appearance of Prader-Willi patients, but there are only a few cephalometric studies for these patients. In this study were included 18 patients with Prader-Willi syndrome and a control group of 18 subjects of both sexes selected based on specific criteria.

Interdisciplinarity in oro-maxillofacial dysmorphism rehabilitation of a patient with Turner syndrome. A clinical case report.

Statement Of The Problem: Turner syndrome is a chromosomal disorder that manifests with short stature, gonadal dysfunction, hypothyroidism, congenital heart disease, and distinct craniofacial features including oro-maxillofacial dysmorphism. This paper presents a case of a 30-year-old female patient with Turner syndrome who sought dental care to improve the dental and facial morphology and restore the oral health. Detailed exobuccal examination revealed complex anomalies.

Adjusting dento-alveolar morphology with orthodontic mini-implants (miniscrews). A clinical case report.

Mini-implants are increasingly popular for creating skeletal anchorage in clinical orthodontics. The aim of this article is to present and discuss the clinical uses, benefits and drawbacks of the miniscrew implants used to reorder and adjust the dento-alveolar morphology of the overerupted maxillary molars. The loss of the lower premolars and molars very often leads to overeruption of the opposing maxillary teeth, combined with insufficient space for prosthetic restorations.
