“I saw the new unbreakable Herbst appliance in Italy a few months ago and I’m really excited because it's a brilliant design and I want to tell everyone all about it.
“During the seminar I will be describing the innovative new design of the appliance. The original Herbst appliance is very effective for a variety of different problems, primarily where the mandible needs to be postured forward. However, the way the components sit in the acrylic of the appliance make it very prone to breakages and so it can be unreliable. The new design of appliance that I will discuss is almost unbreakable; it has exactly the same function but it operates in a different way and is not as flimsy and fragile.
“I will cover the benefits of the new design and the reasons why technicians would want to use the appliance. The design stage will be incorporated and technicians will take away knowledge about how it can be used and also where components can be sourced. This way, technicians can order in the parts and try it out in their own lab.
“I imagine that a lot of technicians will be interested in the new design because it is not just applicable to one specific discipline. Undoubtedly, the Herbst appliance would be used more by orthodontic technicians dealing with specified cases but prosthodontic and denture technicians may also use it occasionally.
“I will join many other presenters throughout the DTS educational programme who are excited about being able to talk to technicians from across the disciplines. Having that cross-over of knowledge is valuable because the conversations, points and questions that arise offer a range of different perspectives that we ourselves may not have considered.
“I think that the co-location of The Dentistry Show and DTS does very well because it’s an exclusive arrangement. Dentists often visit the DTS area to source laboratory services and products, or to seek advice on various techniques and materials. It’s a mutually enjoyable exchange; technicians can also visit stands at The Dentistry Show to see what clinicians are using, which helps us to offer a better service for them in return.
“A lot of the other shows cater more for the clinical side of dentistry. To have a venue with a lab-dedicated area featuring a range of lab-based products and services, as well as lectures designed specifically to interest them, is extremely beneficial. I’ve seen other shows try this approach, of course, but DTS seems to be the best.”
To attend Andrea’s seminar and to take advantage of the wealth of educational and networking opportunities, book your ticket for DTS 2016 today.
DTS 2016 will be held on Friday 22nd and Saturday 23rd April 2016 at the NEC Birmingham, co-located with The Dentistry Show.

The large numbers of implants available come in all shapes and sizes with considerable variations in the material used, the morphology of the implant, the type of abutment connection and the surface characteristics1.
From a chemical point of view, they are currently being manufactured from three groups: metals, ceramics and polymers. These are commonly divided by biocompatibility based on the type of biological response they elicit in the long-term interaction with the host tissue. These include biotolerant (stainless steel, chromium-cobalt alloy), bioinert (titanium, carbon) and bioactive (hydroxylapatite, ceramic oxidized aluminium),.
Titanium remains the material of choice, as it offers no allergic and immunological reactions and no neoplasm formation. Bone grows along the titanium oxide surface, which is formed immediately (9-10 seconds) after contact with air or tissue fluid and can reach a thickness of 2-10nm in one second. This stable surface is biocompatible and provides high corrosion resistance, high passivity and resistance to chemical attack3,.
Implants also vary in design. The majority of modern root form dental implants are threaded, although the thread pitch or profile can differ significantly between manufactures. Threads play an important role in primary stability and long-term success of dental implants. The micro-thread, for example, features small threads around the neck, which engage the dense cortical bone better and distribute occlusal loads more optimally.
Surface properties of the implant can also greatly influence the longevity and function of the implant-supported prosthesis. Rough implant surfaces result in better osseointegration than smooth surfaces, though smooth surfaces seem to have a reduced risk of future bone resorption3.
Surface design is one factor along with length, diameter and shape that affects the contact area; this consequently impacts on stability and the ability of the prosthetic to withstand force. The maximal load is proportional to the total bone-implant contact surface, although the ideal fixture size remains to be determined. However, the dimension of implants should be congruent with the bone available at the surgical site and the treatment plan2.
Implant dentistry is an evolving science with new materials and designs continually being introduced. Working with a laboratory that uses the latest technology and research to create high-quality implants is essential.
Sparkle Dental Labs is one such laboratory that continues to invest in research, development and the latest state-of-the-art technology. The wide range of outstanding implants includes those from the most popular brands, which are all crafted by experienced, highly skilled UK technicians. The high quality materials complement the expert craftsmanship and with full traceability for every item, you are guaranteed first class products every time.
Implantology continues to advance, and by working with a leading lab, dental professionals can liaise with expert technicians to ensure the best implant is chosen for every case, aiding integration and optimising success.

“The new ASC abutment has changed the way we work,” they say. “The titanium interface is more predictable than the old zirconia connection we used to rely on.
“The ability to offer a cement-free retention option is very important. Lots of dentists prefer screw-retained restorations because of the hazards of cement remnants and the complexity of cementing.
“The ASC concept definitely gives us a competitive advantage.”
The ASC abutment and accompanying Omnigrip™ tooling offer new opportunities for the restoration of implants in the aesthetic zone. The abutment can be placed at an angle of up to 25 degrees anywhere in a 360-degree radius, providing enhanced access even when working in limited space. With no cement necessary, there is also no risk of irritation to the gingival tissue.

A recent study found that the vast majority of patients assessed (84%) had very poor levels of denture hygiene[ii]. This was attributed to the lack of hygiene instructions given by dental professionals, as after clinician led patient education, denture cleanliness index (DCI) scores increased significantly2.
Currently there is no clearly defined or regularly used standard or scoring system for determining denture hygiene in the UK. Therefore, the researchers devised the DCI scoring system prior to the audit, which ranges from 0-4. Additional studies are required to refine, test and evaluate the classification, however it could help dental professionals in the future to determine denture hygiene status of patients and highlight any areas of concern2.
Compared to dental care, denture hygiene has received little attention, yet neglecting to look after prostheses can significantly increase an individual’s risk of developing oral infections and systemic diseases[iii],[iv].
Dentures offer a reservoir for microorganisms to thrive and it is well documented that patients wearing partial sets are at a higher risk of developing periodontal disease and dental decay of the teeth directly adjacent to the dentures[v].
Several studies have shown that plaque biofilm accumulates on the internal surface of dentures and certain pathogens may even preferentially colonise on prostheses over oral soft tissues3,[vi]. Acting as a reservoir for bacteria and fungal microorganisms, these pathogens are involved not only in the appearance of local infections like denture stomatitis, but also systemic diseases such as endocarditis, pneumonia and respiratory track infections3.
Problems can also arise if there are any surface defects or other flaws in the denture which are either inherent and due to the fabrication process or acquired due to general use. These can cause imperfections and roughness, which increases the surface area on which bacteria can adhere and potentially colonise[vii].
Furthermore, if the finish is rough it can make cleaning the prosthesis and mechanical removal of the microorganisms difficult, as well as causing discoloration of the denture base materials. The irregularities on the surface can provide niches in which microorganisms are protected from oral hygiene measures, thus allowing the entrapped microbial cells to attach irreversibly to the prosthesis7.
Working with a laboratory, such as Sparkle Dental Labs, that complies with all of the current standards and regulations, uses the very best materials and creates dentures that fit perfectly is essential. The renowned company are able to offer complete traceability on every item and all dentures are fitted to duplicate models to ensure ultimate precision and patient comfort.
In the future the DCI scoring system could be used to help practitioners to identify patients suffering from poor denture hygiene. However, in the mean time dental professionals are encouraged to continue to fit quality dentures and offer patients oral healthcare advice.
