Molar double tubes: enhancing orthodontic mechanics

The stabilization arch is constructed in 0.016″ or 0.018″ round stainless steel wire. Posteriorly it passes through the accessory tubes and anteriorly it overlies the incisor brackets and is secured...

Standard edgewise technique and its relevance in contemporary fixed appliance therapy part 3: overbite control and space closure

Synchronous straight-wire part 2: application

A male patient aged 14 years, 8 months with average oral hygiene with a Class I malocclusion on a Class I base, increased MMPA and vertical lower facial dimension, had moderate crowding in both arches...

Tensile strength of orthodontic elastomeric ligatures – in vitro

One hundred transparent moulded elastomeric ligatures (Dentaurum, Germany. Batch: 774-5513-00) were selected. The samples were divided into three test groups. Each group had 30 ligatures. The...

A review of the literature relating to transmigrating canines. An illustrated case report

A 21-year-old female reported for a routine dental check-up. On intra-oral examination there were bilaterally retained mandibular deciduous canines (Figure 1 a, b). Further investigation of the...

Update on 2D and 3D digital imaging in orthodontics

Computed radiography was developed by the Fuji imaging company, with the first medical Fuji Computed Radiography (FCR) system being released in 1982. The technology involved the use of photostimulable...

A new dimension in managing the troublesome transmigratory canine

Cone-beam computed tomography (CBCT) has been available for imaging the craniofacial region for around ten years. In comparison with conventional CT, which acquires data as a series of 'slices' using...

Orthodontics and root resorption part 2

Studies using scanning electron microscopy have revealed that root resorption is not only dependent upon time taken and force used, but also the type of tooth movement to which the teeth are...

Synchronous straight-wire part 1: theory

Synchronous Straight–Wire treatment events are integrated, which requires a detailed approach to the planning and monitoring of tooth movement and force application.
