  • Bleaching Trays

    Our custom-made bleaching trays are manufactured from 1mm soft vinyl material. They are available with or without reservoirs and can be finished with a scalloped or skirted edge, depending on your preference.

  • Night Guards

    As the name suggests these are Splints which are worn at night to protect the teeth from clenching and grinding. Normally they are worn over the lower teeth but can also be manufactured to fit the upper teeth.

    We offer three types of pressure-formed Night Guards.
    3mm Soft Bruxism Splint, which is most easily tolerated by the patient.
    2mm Hard Pressure-formed Bruxism Splint.
    3mm Combination Splint, which is soft on the fitting surface and hard on the biting surface.

  • Anti-Snoring Device

    Snoring occurs when the loose muscle tissue in the back of the throat relaxes during sleep, narrowing the airway. As air is forced through the shrunken airway it produces vibration in the back of the throat, ie snoring. An Anti-Snoring Device postures the lower jaw forward, thus keeping the airway fully open and allowing the free passage of air without vibration.

    Anti-Snoring Devices are constructed from a dual-laminate material which is pressure-formed over the upper teeth, normally 5 to 5. Attached to this upper mouthguard is an acrylic jig which positions the lower jaw forward, thus increasing the opening at the back of the throat.

  • Custom Appliances

    We design and fabricate removable orthodontic appliances to individual patient requirements, using nickel-free, stainless steel wire, springs and screws, all housed within an acrylic baseplate.
    Removable appliances are suitable for tipping teeth and expansion.

  • Retainers

    We offer two types of Retainers: Removable and Fixed.

    Removable include traditional Hawley Retainers, which incorporate a labial bow, two Adam’s cribs and an acrylic baseplate. Also Essix Retainers, which are pressure formed using clear plastic Essix ACE material.

    Fixed Retainers are a more long-term solution for holding the teeth in place. They are made from stainless steel, multi strand wire which is fitted to the back of the teeth 3-3.
    They are supplied with a Fitting Jig to aid placement.

    It is vital retainers are worn after orthodontic treatment to ensure teeth are held in their new position while ligaments, bones and gums adapt.

  • Fixed Appliances

    We construct various Fixed Appliances for anchorage, arch expansion or space maintenance. Most appliances can be laser welded reducing the need for the use of solder, which can degrade in the patients’ mouth.

  • Functional Appliances

    These appliances alter the mandible/maxilla position. During patient growth, functional appliances work by using the muscle action of the patient to create orthodontic force. The most commonly prescribed functional appliance is the Twin Block. This consists of upper and lower appliances with angled blocks. When worn together they encourage the lower jaw to grow to full potential thus correcting Class ll Malocclusion. Construction requires upper and lower impressions and a protrusive bite registration.

  • Digital Model Scanning

    We provide a Digital Model Scanning service. Send us your models and we can digitally scan and send these digital files back to you in the standard STL (stereolithography) format,

    If in the future you require a 3D printed model, we can provide this.

  • Study Models: Angled Trimmed

    Angled Trimmed Study Models are poured from a vacuum-mixed super-white orthodontic stone and are angle trimmed to exact bite relationships. They are then hand sculpted, sanded smooth and polished to a high finish.

  • Study Models: Basic

    Basic Study Models are poured in yellow stone, then trimmed in articulation and sanded to a smooth finish.

  • Orthodontic Splints

    More heavy-duty bite splints are used to treat patients that suffer muscle pain from chronic clenching or Bruxing. These splints are manufactured from hard orthodontic resin and can include Adam’s Cribs for retention or a soft fitting surface for comfort. They are normally 3-4mm in thickness and are trimmed with a flat occlusal plane achieving contact with all opposing teeth.

    Gelb Splints are used to treat T.M.J. dysfunction. This lower splint incorporates a chrome lingual bar and ball clasps for retention.

    Stabilisation Splints are used to treat T.M.J. dysfunction and help maintain or stabilise a centric relation prior to restorative work.

    Michigan Splints are made in the maxillary arch and Tanners on the mandibular. These hard, clear acrylic splints both feature canine and anterior guidance with disclusion on excursive movements. We require upper and lower impressions, a facebow registration and a centric relation bite to manufacture these splints.

  • Shockbuster Mouthguards

    A tough, resilient, impact-absorbing mouthguard, which is suitable for all contact sports. The Shockbuster is available in both a standard 4mm thickness and a heavy-duty 5mm thickness.

    The anterior region can also be reinforced with extra lamination if required. A full range of colours and patterns are available to choose from.

    The wearer’s name is incorporated into the inside of the Shockbuster and all mouthguards are supplied with a protective storage case.

  • Selection of Ortho Boxes

    We can provide a selection of Orthodontic boxes in various sizes and colours including glitter effect. They all have their own carry cord and can be supplied separately.

A custom made device means any device specially made in accordance with a duly qualified Medical Practitioners written prescription. Below is some downloadable technicial information relating to all our orthodontic products and their material properties.

What type of Anti-Snoring devices do you make?

We make Proform type Anti-Snoring devices.

What impressions are required for Anti-Snoring devices?

High quality upper and lower impressions must be supplied, with good impression depth of the lower lingual area, as this is where the acrylic positioning jig will be seated.

Do I need to supply a bite registration for an Anti-Snoring device?

Yes, please supply a wax bite registration in a closed, relaxed position. We will then use this wax bite as a starting position.

Can you make Anti-Snoring devices for patients who wear dentures?

The device is designed to fit over the upper teeth 5-5 and rest upon the lower teeth 3-3. Therefore, it is unsuitable for edentulous patients.

How does an Anti-Snoring device work?

Anti-Snoring devices, also known as mandibular advancement devices (MAD), are designed to reposition the lower jaw forward. This increases the airway space at the back of the throat, which should lessen the vibration of the tissue at the back of the throat (snoring).

Is an Anti-Snoring device comfortable to wear?

Yes, but patients may experience slight muscular discomfort for the first 5-10 days of use.

What colour can mouth guards be made in?

Our Shockbuster mouth guards can be manufactured in single colour or a combination of colours, to suit your personal choice or team requirements.

What thickness are your mouth guards?

Mouth guards range from a standard 4mm-5mm in thickness.

Do you make gum shields for boxers and martial arts?

Yes. These type of mouth guards are reinforced in the 3-3 labial area. An upper and lower impression is required to enable a bite to be determined, allowing the lower to occlude into the gum shield.
