ZIRCONIA PORCELAIN BONDED CROWNS AND BRIDGES

Here at Toothworx we design and mill all our zirconia frameworks onsite using specifically chosen Zirconia’s that we have tried and tested to fabricate high strength, highly translucent and Dentine shaded frameworks designed to a reduced contour of the final restoration maximizing strength without compromise to final aesthetics that are then layered with a porcelain veneer to allow for optimum aesthetics of the final restoration. 
This type of crowns offers the clinician and patients with optimal restorations that exhibit high aesthetics, strength and biocompatibility. 
With our expertise and years of experience we can produce a crown or bridge that mimics the patient’s natural dentition including internal cracks, enamel effects and small subtle staining that allows a patient specific bespoke restoration to be created.

BESPOKE SHADE TAKING SERVICE

Our Bespoke shade taking service both Inlab and at surgery has become very popular with our clinicians and their patients alike, especially in the private high end cases under taken by the lab when matching the colour perfectly of Patients Natural dentition is vital in fabricating bespoke restorations.

At The Lab there is a dedicated shade taking Area which has natural Daylight Bulb Lighting in order to give us the best possible light to shade take and also to see the little characteristics of the patients natural dentition such as enamel cracks and staining.

Patients are welcomed to attend the lab at their convenience and once at the appointment they are seen personally by our highly trained ceramists that will be carrying out the fabrication their crown, bridge or other restoration, we also take photographs of each case using the latest DSLR camera the photographs are then displayed on the screen to the patient allowing them the opportunity to ensure that they are happy with the shade match and tooth mapping we have carried out. The patient is also shown various smile design pictures and asked for any feedback they would like to add to their final restoration.

We offer this service completely free in private cases at the laboratory but also offer a surgery visit service where the similar inlab service is carried out.

We also offer at the lab using the latest CAD software virtual smile designs where examples of what we can achieve in complete smile makeovers can be demonstrated. From this study models can be 3d Printed inlab and also smile trials can be fabricated so the patient can see in their mouth what the final restorations would look like before they are completed in Ceramic.

IVOCLAR EMAX CROWNS & BRIDGES

Ivoclar Emax is the leading all ceramic restoration system we offer two types of emax restoration here at Toothworx. The first is a monolithic full contour pressed restoration that allow optimal aesthetics by means of subtle surface staining to mimic that of a natural tooth. 

The second Emax restoration is a reduced contour crown that is Thinly layered with porcelain to optimize the already present aesthetics of the material and to include subtle internal and tooth surface effects to mimic that of the patient’s natural dentition.

ZIRCONIA MONOLITHIC CROWNS & BRIDGES

Monolithic Full Contour Zirconia Crowns and Bridges

At Toothworx dental laboratory our Zirconia Dental Restorations are designed using our 3shape scanner and then Milled In-House by our VHF CAM 5-S2 milling machine ensuring full control over the fabrication of our restorations also using only a very high-quality of Zirconia material which can be used for all types of indications ranging from single unit crowns to 12-unit bridges and customized full contour screw retained implant abutments. 

Full contour monolithic Zirconia provides dentists with an alternative to a traditional PFM that exceeds both clinical and patient demand for superior aesthetics, strength and function. Therefore, even the most challenging cases can be fabricated.
Here at Toothworx we only use Pre- Shaded Zirconia this therefore provides us with a consistent even shade throughout the entire restoration which therefore offers our dental technicians an efficient and reliable method for producing highly aesthetic monolithic Zirconia restorations.

This unique system consists pre-shaded Zirconia discs that are then expertly surface stained to achieve life like tooth restorations. By utilizing these pre-shaded discs, we can simply and consistently produce all 16 Vita A-D shades as well as bleach shades. No dipping or use of coloring liquids is required at this point in the process, helping to ensure the consistent aesthetic outcome. By Using Slight Pre- Sinter Staining Liquids, we can create Bespoke patient specific restorations that can easily mimic the patient’s natural dentition. We are also able to surface stain post sintered restorations and micro layer translucent porcelain in areas if desired to create slight adjustments to aesthetics to produce bespoke finished crowns.

Zirconia has become a preferred material of choice, as it offers exceptional strength combined with the beauty that your patients desire. Monolithic Zirconia Restorations offers your patients an aesthetic all–ceramic alternative to metal restoration that naturally mimics the characterization and translucency of natural teeth providing them with highly aesthetic and strong final restorations.

ToothWorx Dental Laboratory offer a wide range of monolithic zirconia solutions ranging from pre-shaded Monolithic crowns and bridges where one shade is required to the latest multi layered highly aesthetic crowns and bridges. 

We have also developed our own internal and external staining technique of creating bespoke monolithic Zirconia restorations to match the dentition of patients existing natural teeth and can mimic the properties of Emax crowns using the new Ivoclar Emax Zirconia but with the added strength of zirconia from 600 mpa to 1200mpa dependent on requirements.

SLM PBC's & BRIDGES

Toothworx after many years of casting long span porcelain bonded bridges and single crowns have opted to fabricate all our porcelain bonded restorations using the latest SLM technology to print our alloy substructures then layer using Ivoclar Inline Highly Aesthetic Porcelain.

This allows us to fabricate solid one-piece alloy Crown and Bridge frameworks to support our aesthetic porcelain layering with the confidence of no possible breakages on solder joints. 

Also by designing the frameworks digitally there is no inclusions of framework shrinkage or warpage allowing for a precise accurate fitting substructure. The restorations are available in both precious and non-precious alloys dependent on requirements.

How SLM Frameworks are made:

Laser PFM frameworks are created using additive manufacturing. The high-tech laser melting process, which is sometimes called laser sintering, builds up each framework in a series of successive 0.030 mm layers.

A high-powered laser beam is focused onto a flat bed of powdered metal (in this case CE marked CoCr) and the selected areas fuse into a thin solid layer. A second layer of powder is then spread over the first, before the laser creates the next ‘slice’ of each LaserPFM framework.

When every layer has been built up, the solid frameworks are taken from the machine, grit blasted,
polished, inspected and ultrasonically cleaned.

Advantages of SLM Frameworks
  • Fixed price per unit with our CoCr Frameworks (No Added Alloy Cost only with Precious alloy option)
  • The Non- Precious option are totally Free of nickel, cadmium and beryllium so no risk of allergies.
  • Precision optimal Fit due to cad design process.
  • CAD Designed for optimal porcelain support and bridge frameworks all in one piece so no chance of joint failure.
  • Excellent fit, less chair time, less adjustment
  • No change to traditional porcelain techniques and materials
  • All bridges are stress relieved for increased accuracy
  • Manufactured in accordance with ISO 13485

AESTHETIC COMPOSITE RESTORATIONS

GC GRADIA:

A restoration made from composite material has many beneficial properties such as strength and durability, but although composite also has good aesthetic qualities, it does not give the natural tooth appearance of a porcelain. That is, until now!

GC GRADIA is a unique light-cured Micro-Ceramic-Composite system for crowns, bridges, inlays and veneers, which compared to conventional composites gives restorations with a colour tone close to that of natural teeth. 

A product of GC research, GC GRADIA’s more natural tooth appearance has been achieved by developing its resin colour tones in conjunction with its application technique. This combined approach to development has created a system where the final restoration is of optimum hue, brightness and chroma, whilst minimizing the paleness inherent with composites. 

The result is a restoration with an opalescence comparable to porcelains and close to natural teeth which would previously have been impossible to attain using traditional composite materials.

BREDENT HIPC:

ToothWorx dental Laboratory also use our high-tech CAD software to design full contour Crowns, Inlays, onlays and veneers to be milled in our onsite milling suite using Bredent HIPC composite material. 

HIPC (High Impact Polymer Composite) is an amorphic, cross linked material which therefore gives higher physical values than conventional PMMA or composite.

The HIPC restorations are then highly polished and stained using GC Opti glaze to produce highly aesthetic restorations. 
In the high aesthetic zone of the mouth we mill our HIPC substructures to allow optimal support of enamel composite to aid in the required high aesthetics.

INDICATIONS OF COMPOSITE:
Anterior Full Contour Crowns
Posterior Full Contour Crowns
Veneers
Occlusal Tabletops
Inlays/Onlays
HIPC Bridges (up to 3 Units)

AESTHETIC PMMA MILLED TEMPORARY CROWNS & BRIDGES

Highly Aesthetic Temporary Restorations are designed on our cad systems and milled in lab to produce a long term temporary solution to patients. 

The restorations can be either mono coloured or Multi-layered Dependent on requirements Dentists where healing is required before definitive restorations are to be fitted. 

These can also be used as a diagnostic tool in patients’ treatment plans on deciding aesthetic requirements, Function and specific shades of final restorations.

FULL GOLD CROWNS & BRIDGES

Gold crowns are able to withstand heavy forces from chewing. They do not chip or break, making them a long-lasting dental restoration.

If a tooth with a gold crown breaks, it is generally because the underlying tooth structure has fractured or decayed. Gold crowns are not immune to becoming loose, especially if you are eating foods

Gold crowns also cause the least wear on the opposing tooth.
For patients that grind their teeth or have a heavy bite, a gold crown will typically cause the same amount of wear on the teeth, compared to the tooth's natural enamel.

At Toothworx we offer a range of full anatomical Gold restorations that are available in:
  • 60% Gold Content
  • 40%Gold Content
  • 10% Gold Content

DIGITAL DENTAL SPLINTS

Toothworx Dental Laboratory utilise the latest digital Cad Software to Fabricate optimal accuracy, communication and convenience for removable Dental Splints - from the scan, design and model production to The final fabrication of the prosthesis. 

In the past splints have been made from a hard acrylic or a soft, polyvinyl material. The hard-acrylic splints provide the patient with an adjustable occlusal surface but usually require substantial chair time to make the appliance fit comfortably. The soft splints, although more comfortable for the patient, do not lend themselves to adjustment and repair. 

Our custom, advanced surgical, TMJ and bruxism splints are constructed to your occlusal plane specifications on the upper or lower arch and cover all modern designs of Bite Splints. 
All our splints are milled inhouse or digitally printed on our 3d printers to allow us to control every aspect of their fabrication ensuring quality, strong and functional splints.

Types of Digital Splints We Offer:

Michigan Tanner Appliances:
Designed to treat the dysfunction of the TMJ and to control bruxism phenomenon without the need for metal clasps.

Flat Plane Hard Bite Splint
The hard-flat plane splint is fabricated on the maxillary or mandibular arch to achieve balanced contacts with all opposing dentition and incisal anterior teeth incisal edges. These are made with hard acrylic, though retention and comfort can be maximised by incorporating a soft lining if desired.

Soft Bite Raising Appliance
Soft Bite Appliances are the most commonly prescribed splint for Bruxism and TMD. However, over a short period such guards will typically deteriorate and need replacing. The soft guard protects teeth by separating and preventing them from meeting each other. These are also ideal to be described where patients have had new bespoke crowns fitted to prevent damage in the early stages.

Nightguards
These devices are worn on teeth during the night to protect from nocturnal grinding and clenching, night guards are great for preventing tooth wear in patients that do not suffer from extreme bruxism. They’re fabricated out of soft polyvinyl material.

Essix Retainers:
An Essix retainer is used to retain the teeth in their corrected position in the same way that a Hawley retainer does, but in made from a solid piece of clear polyvinylchloride (PVC) or polypropylene that is vacuum formed to fit around the patient’s arch.

Essix retainers, if worn 24 hours per day, do not allow the upper and lower teeth to touch because plastic covers the chewing surfaces of the teeth. Some orthodontists feel that it is important for the top and bottom chewing surfaces to meet to allow for “favourable settling” to occur. 

We Are Happy To also discuss Custom designed appliances with you.
Indications:
  • To protect natural dentition or new crowns, bridges and veneers from 
  • abnormal occlusal forces caused by clenching and bruxism
  • Where a splint with superior fit is required
  • Where positive retention without the use of clasps is desired
  • allow the condyle to seat in centric relation
  • provide diagnostic information – if a patient quickly becomes comfortable wearing a splint, then the disorder may indicate a muscular problem. If the symptoms get worse with splint wear, there may be an internal derangement (disc) problem
  • interrupt periodontal ligament proprioception
  • alleviate the pain of many types of temporomandibular disorders and bruxism.
Advantages:
  • Adjustable as treatment progresses
  • Assist resolution of pain and symptoms
  • Long edentulous spans where denture teeth are required in the splint
  • As with any appliance, appliance may break down under extreme 
  • bruxism pressure
