The Effect of the Passive Lingual Archwire on the Lower Denture.
The Measurement of Utility Archwire Forces.
Etiology and diagnosis of anterior openbite malocclusion, with a detailed presentation of a treatment approach using multiloop Edgewise archwires.
Calculating Continuous Archwire Forces     APPLIANCE  ARCHWIRE  FORCE       2009/2/17
A method for evaluating the forces applied by a continuous archwire on all of the teeth engaged by the wire. A demonstration analysis shows that force is delivered to all of the teeth engaged by the...
Objective: To examine the effects of three different parameters—pH value, type of archwire, and length of immersion—on release of metal ions from orthodontic appliances. Materials and Methods: Simu...
The finite element method has been used to determine the stress distribution generated by the initial placement of a simulated preset bracket-type orthodontic appliance utilizing titanium-nickel all...
This study tested the strength of ceramic orthodontic brackets subjected to mesial-distal tipping forces on five types of pre-adjusted, maxillary right central incisor ceramic twin brackets for bo...
Static frictional resistances were compared between Teflon-coated stainless steel and clear elastomeric ligatures used with various combinations of brackets and archwires. Stainless steel metal, p...
This prospective clinical study was undertaken to analyze adult skeletodental changes induced by a reverse curve mushroom archwire during the initial stage of treatment. Lateral cephalograms from ...
Recent developments in material science have presented newer archwire materials as well as improvements in the properties of existing ones. Proper selection and understanding of the biomechanical ...
Welding attachments to archwires can produce change in their physical as well as mechanical properties. This study evaluated three archwire alloy materials—stainless steel, Beta titanium, and Timo...
Fixed or removable orthodontic appliances impede the maintenance of oral hygiene and result in plaque accumulation. Plaque retention surrounding orthodontic appliances leads to enamel demineralizati...
Most orthodontic brackets and archwires made from stainless steel or nickel (Ni)–titanium (Ti) alloys can release metal ions into the saliva. This study measures the amounts of metal released from...
