SOLID Retainer System

The Future is SOLID:

The SOLID Retainer System is an all-new concept in orthodontic retention.  It represents a seminal moment in the evolution and future of orthodontic retention with an absolute and invisible solution for prevention of post-alignment relapse.

The SOLID Retainer System stands for Single-visit Orthodontic Lingual and Invisible Dual Retainer System.

By combining an invisible fixed-lingual retainer WITH a removable acrylic retainer we have developed the World’s only invisible dual retention system.  This means you can place two different types of retainer in only one appointment.

The Cfast SOLID Retention System 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.

The SOLID Retention System is a hybrid-designed retainer, which utilises fibre-reinforced composite technology and modern bonding techniques to create a virtually invisible fixed-lingual retainer.  This lingual retainer is complemented by a traditional removable acrylic retainer.

Not only is this a revolutionary advancement in retainer design, but we have additionally revolutionised retainer placement so you can now place this retainer WITH the orthodontic fixed brackets still in place on the teeth.  This ensures there is absolutely no tooth movement before or after the traditional bracket de-bond process.

Only one impression is necessary and, with only one fitting appointment for your patient, you will save material costs and surgery time, making this the most cost-effective and only invisible dual retainer system in the World

SOLID Practicality, SOLID Reliability and SOLID Profitability.  The future of orthodontic retention is SOLID with the CFast Retention System.

FAQs:

What is the concept behind the SOLID retainer system?

With the increasing movement toward cosmetically and aesthetically focused dental treatment – and the increasing trend for adult cosmetic tooth alignment – we knew there was a desperate need for a retention system that met both the high aesthetic demands of our patients and also the objectives and properties of traditional orthodontic retention devices. It also needed to remain cost-effective, with predictable reliability for the dentist.

The SOLID Retention System is an invisible solution to orthodontic retention that is more discreet and well-tolerated than any other retention product.  It satisfies both the patient’s expectations for invisible solutions and also the necessary properties for orthodontic retention of strength, stability and survivability.

As we can create two retainers from only one impression and with only one fitting appointment, it becomes a more efficient and profitable procedure to offer our patients.

How does it work?

The SOLID Retention System allows the dentist to place a fibre-reinforced composite fixed retainer onto the lingual surfaces of upper or lower teeth in a simple one-stage application.

The retainer can be placed before orthodontic brackets are removed to ensure there is absolutely no post-alignment movement.

The indirect-retainer is provided within an acrylic stent that allows immediate placement onto the teeth.  After the usual light-curing process, the stent is removed and the fixed retainer remains securely bonded to the teeth. The only preparation necessary is to etch and bond the lingual surfaces of the teeth you are planning to place the lingual-fixed retainer on to.

After quickly polishing the retainer, the process is completed.  The original stent is given to the patient as their additional and supplemental removable retainer and they are advised to wear this at night.  They are provided with an all-new design and modern aluminium retainer box as a complimentary gift with their treatment. This is included as part of the CFast SOLID Retainer System.

Why is it better than other fixed retainers on the market?

Not only is the SOLID retainer almost completely invisible to the patient, it is also very smooth and very low-profile.  We have found that patient tolerance far exceeds that of a historic fixed-wire retainer, which patients find lumpy and rough and often complain about food debris getting caught between the wire.

The main benefit as far as we are concerned is that you are providing EVERY patient with TWO retainers.  This eliminates the possibility of de-bond or relapse – the possible risks when only one type of retainer is given.

One of the biggest problems of historic fixed-wire retention is de-bond of the wire.  This is due to only a small surface area utilised for bonding the wire per tooth.  Additionally the wire and composite material are incompatible, so there is no inherent strength gained from these two different materials.  The SOLID retainer eliminates this problem by being made from the same composite material and covering a greater area of the tooth surface for enhanced bond strength.

The SOLID retainer contains no metal so is suitable for anyone with a metal-allergy or alloy sensitivity.

Is there an evidence-base to support its use?

Fibre-reinforced composite retainers have been used for many years.  They have always been incredibly technique sensitive due to their very difficult multi-stage direct application to the teeth.  The SOLID Retention system was developed to provide all the known benefits of fibre-reinforced composite retention but deliver it to the dentist in a more cost- and time-effective manner with a very simple insertion procedure.

You can find multiple evidence-based practice research papers supporting this type of retention here:

What do you do if a failure occurs?

As with any composite technique, failure and degradation over time is always possible.  As is recommended with all composite restorations, excellent moisture control and correct bonding protocols must be ensured throughout the procedure to maximise the success.

The SOLID Retainer utilises material that is very strong and specifically chosen for its intended purpose as a retainer.  Failure is unlikely but, should it occur, it can be easily repaired.

Like all composite, our fibre-reinforced composite retainer can be added to by simply roughening the area of concern, placing a phosphoric acid tooth etch for 15 seconds and then rinsing away, followed by a composite bonding agent before placing your repair composite.

Please contact us via the forum and one of our experienced dentists can contact you and explain clearly how to repair any failure you encounter if you are uncertain.

How do patients keep it clean?

The SOLID Retention System has been designed to respect the physiology of the teeth and their periodontal and gingival health, along with the traditional concepts of oral health and to support good hygiene procedures.

The patient is instructed to clean their teeth following your professional guidance in the correct technique to ensure excellent hygiene.

The retainer has a blocking agent that will prevent any composite material from being deposited at the gum margins or in the interproximal embrasures between the teeth.

Once the retainer is placed and polished, the dentist must check all of these embrasures and ensure the patient can adequately clean through these areas with interdental brushes or orthodontic floss.

Who invented the SOLID Retainer System?

Dr Thomas Sealey, a cosmetic dentist based in Essex in the UK, invented the retainer which is patented as ‘The Sealey Retainer’.  Dr Tom is a close friend of CFast and has helped us develop this product and all the guidance to ensure that both dentists and patients alike are extremely satisfied with the product.

Why is there a spare retainer included with SOLID?

CFast are always innovating and trying to give dentists and patients the most for their money, so we decided to include a spare removable retainer for every SOLID customer . The purpose of this retainer is two-fold; this retainer will act as the ‘try-in’ stent before you open your SOLID retainer packaging. If the spare removable retainer fits well, then you can be assured that the SOLID retainer will fit perfectly. You can then go ahead and prepare the teeth following composite bonding protocol before opening your SOLID retainer and activating it with the enclosed flowable composite. After treatment you can tell your patient that they are getting two removable retainers, so that they always have a spare if they lose or break one. The spare retainer will build goodwill with your patients and it is also more cost-effective in the long-run for both of you.

If the spare retainer does not fit well when you try it onto the patients teeth, you have two choices: 1) Take a new impression and send everything back to CFast in the postage box. Do not open the SOLID retainer if the try-in retainer does not fit. 2) If the fit is acceptable then you can place the fixed-composite retainer like you had planned. If the two removables do not fit well over the teeth once it has been placed and finished, then take a new impression at this stage (after bracket removal) and send to CFast for a new removable retainer.

If you do lose or break your removeable retainer don’t forget to contact your dental surgery to request a new one.
