The influence of opaque application methods on the bond strength and final shade of PFM restorations
Publication year: 2010Source: Journal of Dentistry, In Press, Accepted Manuscript, Available online 31 August 2010Daniela, Jörn , J Neil, Waddell , Michael V, Swain Objectives: The aim of this study is to compare the influence of the opaque application method on the adhesion and final shade of porcelain-fused-to-metal restorations. Methods: Four samples (n=12) were cast in a NiCrMo alloy and opaqued using three application methods: aerosol-spray (one application), aerosol-spray (two applications), paste and powder-liquid prior to veneering with dentine porcelain to a thickness of 1.0mm to mimic the clinical thickness of porcelain-fused-to-metal crowns. The porcelain to metal adhesion was determined by measuring the interfacial fracture toughness or strain energy release rate with a fo......

Developments in making patients' orthodontic choices better [Cutting Edge]
This article reviews evidence of the effectiveness of orthodontic information to enable patient involvement in treatment regimens. It critiques the current provision of information with reference to research from the decision and behaviour sciences about how people make sense of information when making treatment decisions.
Findings: Orthodontists provide a lot of verbal and written information about the ‘facts’ of treatment. This type of information is unlikely to facilitate patients’ decisions about, or adherence with, treatments. There is a paucity of evidence describing how: (1) patients make sense of orthodontic problems and treatments, (2) parents manage decision making about their child’s treatment, and (3) variation in information needs across the lifespan an......

Design and management of Twin Blocks: reflections after 30 years of clinical use [Clinical Section]
The objective of this article is to correct some misconceptions that have arisen since the introduction of Twin Blocks, to identify factors leading to reduced efficiency and increased failure rate, and to improve the clinical application of Twin Block technique. (Source: Journal of Orthodontics)...

A clinical strategy for maxillary molar intrusion using orthodontic mini-implants and a customized palatal arch [Clinical Section]
Orthodontic mini-implants are a valuable adjunct in orthodontics and potentially expand the orthodontic treatment envelope. In particular, their use may revolutionize the treatment of anterior openbites through the application of direct molar intrusion. Clinical protocols for mini-implant usage are just beginning to evolve and this paper describes the basis for a new clinical approach and future research, for the orthodontic treatment of anterior openbites.

BOS MOrth cases prize 2008 [Clinical Section]
This paper describes the clinical orthodontic treatment of two cases that were successfully entered for the 2008 intercollegiate MOrth cases prize. The first case describes the management of a 12-year-old female with an increased overjet treated using a Dynamax functional appliance followed by fixed appliances. The second case involves the management of a class II division I malocclusion complicated by an unerupted maxillary central incisor and a mandibular first molar of poor prognosis.

Decontamination procedures for tungsten carbide debonding burs: a cross-sectional survey of hospital-based orthodontic departments [Scientific Section]
Conclusions: There is wide variation in the handling of TCDBs in UK hospital-based orthodontic departments. Decontamination of new TCDBs prior to initial use is carried out by less than a third of departments. Despite their classification as reusable devices, just over half discard TCDBs after single use. However, among those that do reuse TCDBs, almost all decontaminate them correctly. (Source: Journal of Orthodontics)...

The effect of different surface preparation techniques on the survival probabilities of orthodontic brackets bonded to nanofill composite resin [Scientific Section]
Conclusion: Bonding orthodontic brackets to nanofill composite resin materials may result in lower bond strengths and special surface preparation techniques might be required to avoid increased numbers of bond failures. Surface treatment with sandblasting followed by plastic conditioner could increase the survival probability. The use of a diamond bur, orthophosphoric etching or hydrofluoric etching cannot be recommended. (Source: Journal of Orthodontics)...

Is early class III protraction facemask treatment effective? A multicentre, randomized, controlled trial: 15-month follow-up [Scientific Section]
Conclusions: Early class III orthopaedic treatment, with protraction facemask, in patients under 10 years of age, is skeletally and dentally effective in the short term and does not result in TMJ dysfunction. Seventy per cent of patients had successful treatment, defined as achieving a positive overjet. However, early treatment does not seem to confer a clinically significant psychosocial benefit.
