FAQS
Built for precision. Built to last. Our CE certified cobalt-chrome frameworks exceed International Standards, combining exceptional strength with a fine, accurate fit. Nickel and beryllium free, they are biocompatible and suitable for even the most sensitivity-prone patients — giving dentists and patients complete confidence.
For patients who regard their denture as more than a prosthetic — but a mark of refinement — our gold frameworks represent the pinnacle of dental craftsmanship. Cast from a high precious-metal alloy, they offer outstanding biocompatibility, a mirror-polished finish, and an inherent resistance to plaque and bacteria. Where aesthetics and quality are non-negotiable, gold delivers.
The ideal choice for patients with metal allergies. Titanium’s outstanding biocompatibility makes it one of the most patient-friendly materials available, while its lightweight strength suits full plates and simpler framework designs particularly well. The finish mirrors the clean look of chrome, with a refined, low-lustre appearance.
Our acetal resin clasps are the ideal solution for patients who want effective retention without the visibility of metal. Highly flexible and retentive, they engage deep undercuts that metal clasps cannot — while blending naturally with the surrounding dentition through a full range of Vita-matched shades. They can also be retrofitted to existing dentures, making them a versatile choice.
Made from a monomer-free, crystalline thermoplastic, acetal resin delivers outstanding durability, elastic memory, and biocompatibility — stable across a wide pH range and resistant to the stresses of daily wear. Non-allergenic and non-toxic, it is a material as kind to patients as it is effective in practice.
Available in 20 tooth shades matched to the Vita Shade Guide, plus 3 gum-pink options.
Key Features & Benefits:
High abrasion resistance
Excellent tensile and shock strength
High elastic memory
Low thermal conductivity and rigidity
Non-allergenic, non-toxic
Remains stable with exposure to a 4–9 pH range, chemicals, humidity and repeated stress
Available in 20 Vita-matched tooth shades, plus 3 gum-pink shades
All the benefits of acetal resin — in one complete unit. Our acetal resin bridge features integrated retentive clasps, full Vita shade matching, and the same monomer-free, non-allergenic properties as our acetal clasps. Suitable as a temporary or permanent restoration, it is a versatile, metal-free solution built for both performance and aesthetics.
Rhein 83 Ball Attachment Versatile, reliable, and our most requested overdenture attachment. The Rhein 83 ball attachment is available in 2.5mm and 1.8mm diameters, corrects implant abutment angulation, and works in combination with posts or crowns. Colour-coded nylon caps provide customisable retention levels, snap securely over the ball, and can be incorporated into the framework or cold-cured chairside — and replaced easily when worn.
Locator Attachments (from ZestAnchors)
A globally trusted overdenture solution. Locator attachments from Zest Anchors feature a low-profile, self-aligning design that adapts to a wide range of implant angulations. The denture is constructed clear of the attachments and fitted chairside for a precise, accurate result — every time.
Precision welding where others can’t. Our laser welder works across virtually all high-melting-point dental materials, producing narrow, deep joints stronger than the material itself — with minimal heat transfer to surrounding structures. We can add clasps and retention features just millimetres from acrylic work, safely and accurately. A dedicated polishing setting ensures every weld finishes clean, seamless, and strong.
We use only the finest CE certified cobalt-chrome alloys — selected to satisfy the restorative requirements most important to dentists, including biocompatibility and resistance to breakage. Our frameworks exceed all International Standards, allowing us to produce dentures that are exceptionally fine yet strong enough to withstand even the highest masticatory forces.
Our chosen alloy is nickel and beryllium free, making it an excellent choice for patients with metal sensitivities or allergy concerns — delivering strength, durability, and lasting comfort without compromise.
Complex cases handled with confidence. As a full-service laboratory, McDowell + Service brings together expertise from every department to plan and manufacture the most technically demanding combination dentures. From crowns and slide attachments to ball, Locator, and Magfit magnetic attachments — every component is carefully integrated for a precise, reliable result.
(From Pressing Dental, Technical Information)
“The “TSM ACETAL DENTAL” is a thermoplastic technopolymer with a monomer-free crystalline structure and is a product of formaldehyde polymerization. Its characteristics are: high resistance to abrasion, excellent tensile and shock strength, high elastic memory, low thermal conductance and rigidity. Furthermore, it is neither allergenic, nor toxic. These features, coupled with remarkable aesthetic performance, make “TSM Acetal Dental” a good substitute for acrylic resins and metals in many prosthetic applications. The above-mentioned features remain stable under different operational conditions such as: exposure to a 4 - 9 PH range, chemicals, humidity, cyclically repeated stresses, etc.”
(from ZestAnchors)
“Until now, choosing a narrow diameter implant often meant a sacrifice in attachment performance and ultimately patient satisfaction. In order to provide patients with the quality of care that they desire, an increasing number of clinicians are now recognizing the unique benefits of using the next generation of narrow diameter implants for retaining overdentures.
The LOCATOR Overdenture Implant System (LODI) comes complete with the world’s leading overdenture attachment. LODI has answered clinician requests and patient demands for a less invasive, predictable and cost conscious technique for securing dentures.
The LODI system now allows you to treat patients with the minimum standard of care of an implant supported overdenture,* at a reduced cost and with greater satisfaction”.

We usually ask for 5 working days in the lab, but the work is dispatched upon completion.
For best results a special tray impression in either alginate or silicone, whatever you feel can produce the most accuracy.
Yes, our Wironium chrome framework alloy is nickel and beryllium free.
Yes, all our safety data sheets and material composition are in our technical information section or Downloads section.
Yes, we can laser weld fractures, breaks and in some cases extend chrome dentures.
Yes, in most cases we can weld on tooth retention or weld a custom cast metal extension to retain additional teeth.
Where possible, we can replace these with acetal resin tooth coloured clasps. If this is not possible due to space limitations, we can simply mask the metal with a tooth coloured opaquer.
We can usually add additional clasps, either wrought, stainless steel, gold or even acetal tooth coloured clasps.
They are aesthetic flexible, retentive, tooth coloured clasps which come in all Vita shades.
They are very successful but like anything, when they are pushed beyond their elastic limits or exposed to corrosive cleaners, it is possible for them to weaken and break. They are replaceable.
In most cases we can if there is enough room and where there is a saddle or acrylic tooth next to the clasp location.
Yes, if there is enough room and where there is a saddle or acrylic tooth next to the clasp location.
We only recommend occlusal approaching as they are more successful and aesthetic.
Yes, crowns can be constructed with mesial or distal male rhein attachments then the chrome framework incorporating the nylon rhein cap will snap over the crowns and increase retention.
Yes, replacing the nylon caps solves this. We can either replace the nylon caps on the denture in the lab or send you out nylon caps for replacement chair side. It is recommended that these caps should be changed every 12 months.

The colour of the caps relate to how retentive the cap is.
Yes, although sometimes it is best to laser weld on a new clasp.
We can laser weld any clasp metal to chrome but only titanium to titanium.
Yes if we have a situ impression and can align the denture up again.
A laser weld is usually stronger than the material being welded so it is unlikely to break again in the same place.
