Fracture strength of orthodontic mini-implants
Objective: This study aimed at evaluating the design and dimensions of five different brands of orthodontic mini-implants, as well as their influence on torsional fracture strength. Methods: Fifty mini-implants were divided into five groups corresponding to different manufactures (DEN, RMO, CON, NEO, SIN). Twenty-five mini-implants were subjected to fracture test by torsion in the neck and t...
متن کاملAssessment of flexural strength and fracture of orthodontic mini-implants
Objective: This study was designed to assess the deformation and fracture of orthodontic miniimplants of different commercial brands by submitting them to loads perpendicularly applied along their lengths. Materials and Methods: A total of 75 mini-implants were divided into five groups (n=15): M (Mondeal, Tuttlingen, Germany), N (Neodent, Curitiba, Brasil), I (INP, São Paulo, Brazil), S (SIN, S...
متن کاملEvaluation of Fracture Resistance of Orthodontic Mini-implants in the Transmucosal Profile Region.
AIM This study sought to compare the fracture resistance of three trademarked orthodontic mini-implants in the transmucosal profile region. Thirty-six mini-implants of three different brands, separated into groups I, II and III, were tested. Each group consisted of 12 mini-implants of 6 mm in length. The mean diameter and length of the transmucosal profile of the mini-implants were 1.90 and 2.0...
متن کاملEvaluation of cytotoxicity and corrosion resistance of orthodontic mini-implants
Objective: To evaluate and compare in vitro cytotoxicity and corrosion resistance of mini-implants from three different commercial brands used for orthodontic anchorage. Methods: Six mini-implants (Conexão(tm), Neodent(tm) and SIN(tm)) were separately immersed in artificial saliva (pH 6.76) for 30 and 60 days. The cytotoxicity of the corrosion extracts was assessed in L929 cell cultures usin...
متن کاملResistance to immediate orthodontic loading of surface-treated mini-implants.
OBJECTIVE To test the hypothesis that there is no difference in the stability and resistance to orthodontic forces of immediately loaded sandblasted and acid-etched (SAE) mini-implants and those of machined-surface implants of the same size and shape. MATERIALS AND METHODS Two types of mini-implants were used in the tibiae of 44 rabbits; some had an SAE surface and some had machined surfaces....
