Abstract
Abstract This report introduces the Hawlix, a hybrid thermoformed and cold-cured retainer. It was developed to overcome the limitations that modified Hawley retainers possess when used in patients with bounded saddles, attributable to dental trauma or hypodontia. The Hawlix can be used as an intermediate retainer while a patient is waiting to receive restorative treatment. Some of the advantages of the Hawlix over the modified Hawley retainer include: superior aesthetics, cost-effectiveness, ease of manufacture, adequate resistance to fracture, preservation of a residual ridge, and precise space maintenance.
Highlights
The retention phase of orthodontic treatment aims to maintain the teeth in their corrected positions at the conclusion of active orthodontic treatment
This is achieved by preventing relapse, defined as ‘the return following correction, of features of the original malocclusion.’[1] the vacuum-formed retainer (VFR) is a popularly prescribed retainer for most orthodontic patients,[2] it is not suitable for all
When compared with a VFR, a Hawley retainer is less cost-effective and patients report reduced satisfaction with respect to aesthetics and speech.[3]. These factors may negatively influence compliance with a prescribed retention regimen associated with a modified Hawley retainer
Summary
The retention phase of orthodontic treatment aims to maintain the teeth in their corrected positions at the conclusion of active orthodontic treatment. This is achieved by preventing relapse, defined as ‘the return following correction, of features of the original malocclusion.’[1] the vacuum-formed retainer (VFR) is a popularly prescribed retainer for most orthodontic patients,[2] it is not suitable for all. The Hawlix is delivered immediately at the end of active orthodontic treatment when fixed appliances are debonded It is used during the initial retention phase while waiting for the reorganisation of the largely collagen fibres of the periodontal ligament to stabilise before restorative treatment is provided. Similar to the hybrid VFR,[5] the Hawlix can be worn during eating, avoiding social embarrassment normally associated with alternative retainers
