The SOLID Retainer System – it stands for Single-visit Orthodontic Lingual and Invisible Dual Retainer System – is an all-new concept in orthodontic retention.
In a bid to prevent post-alignment relapse, SOLID combines an invisible fixed-lingual retainer with a removable acrylic retainer, which means clinicians can place two different types of retainer in only one appointment.
And even better, SOLID has revolutionised retainer placement so dentists can now place this retainer WITH the orthodontic fixed brackets still in place on the teeth, thus ensuring zero tooth movement before or after the traditional bracket de-bond process.
The system also satisfies advice from members of both the British Orthodontic Society and American Association of Orthodontics who recommend provision of fixed-lingual and removable retention for more security in limiting the potential of orthodontic relapse.
Created by Dr Thomas Sealey, the Cfast SOLID Retention System is a hybrid-designed retainer that utilises fibre-reinforced composite technology and modern bonding techniques to create a virtually invisible fixed lingual retainer, that’s complemented by a traditional removable acrylic retainer.
Thomas explains: ‘I developed the SOLID retainer to be placed before brackets are removed to ensure absolutely no tooth movement can occur from your final and perfect end positioning. The SOLID retainer can also be used after clear positioner orthodontics. In this scenario, once you have achieved the correct alignment of your final positioner, you can simply send the last 3D-printed model to Cfast and they will make you the SOLID retainer – you don’t even need to see the patient for an impression.
‘Without having to remove orthodontic brackets, you can place and polish a SOLID retainer in less than 10 minutes.’
He adds: ‘Cfast SOLID is not only the fastest placed invisible dual-retainer system in the world, it also provides a second removable Essix retainer – this spare retainer is also a great sales point for the patient as new retainers can usually cost them around £100.
‘The SOLID invisible retainers are kept at least 1.5mm from the incisal edge and from the gum level to ensure ease of cleaning. In the past, the final cosmetic result was often spoiled with visible wire retainers or ceramic retainers that made the lower teeth look twice as thick as they should. SOLID is discreet, easy to clean, totally smooth and requires no additional cost to the dentist or patient. As the “ortho-dentist” has evolved to provide short-term tooth alignment for the cosmetically focused patient, so orthodontic retention has evolved to meet the needs of the modern patient in the form of SOLID.’
