Use of Vitremer Core Buildup/Restorative Cement (3M Dental Products Division) as a luting cement for orthodontic bands and space maintainers was described in 1994. For use as a luting agent, the restorative cement is mixed with a slightly lower powder liquid ratio so the blend is more fluid than one used for a dental restoration. A chief advantage of using Vitremer Restorative Cement for luting...

The aim of this study was to compare the mechanical strength of different joints made by conventional brazing, TIG and laser welding with and without filling material. Five standardized joining configurations of orthodontic wire in spring hard quality were used: round, cross, 3 mm length, 9 mm length and 7 mm to orthodontic band. The joints were made by five different methods: brazing, tungsten...

introduction: one of the most common problems we confront in orthodontic therapy is periodontal diseases. initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. however, it seems necessary to assess va...

The retention of orthodontic bands cemented on primary molar stainless steel crowns (SSC) was studied in vitro. Unitek maxillary and mandibular 1st and 2nd primary molar SSC were fitted with one of four commonly used orthodontic bands (Unitek regular, Unitek narrow, Rocky Mountain, or custom bands made from SSC) using glass ionomer cement. The cemented samples were tested for their resistance t...

PURPOSE Manufacturers commonly provide information on the physical properties of dental materials, but information on their antibacterial properties is often missing. This study determined the antibacterial properties of four currently used orthodontic band cements against three different strains of Streptococcus mutans. METHODS The cements utilized were Durelon, Ketac, Mizzy Zinc Phosphate, ...

Dental materials especially orthodontic elastics often get embedded in gingival tissues due to iatrogenic factors. If retained for a long time, inflammatory response starts as asymptomatic crestal bone loss and may progress to severe periodontal abscess. Unsupported orthodontic elastics used for diastema closure may result in exfoliation of teeth, while elastic separators may get embedded in in...

Introduction: Stainless steel alloy used in orthodontics has elements such as iron - magnesium and chromium , which may be released due to corrosion in the mouth . The aim of this study was to evaluate the changes of these elements in the saliva of patients undergoing fixed orthodontic treatment. Methods: In a clinical study with simple non- random sampling , 1ml saliva of 11 patients (7 fem...

Ingestion of a broken part of fixed orthodontic appliance is a potential complication during orthodontic treatment. We report a case of accidental ingestion of molar band and its subsequent diagnosis followed by endoscopic retrieval method. Although prevention of such incidence is the best method at the same time management of such an event is also crucial. The objective of this paper is to dra...
