Chris McMahon introduces BPS dentures and how they are transforming what dentists and labs can offer their patients.

Although the efforts undertaken in the field of preventive care have had a substantial impact on the dental industry, sooner or later many patients still have to have some of their natural teeth replaced. With consumer demand for affordable yet aesthetically pleasing dentures at an all-time high, providing edentulous patients with new and improved prosthetics is one of the biggest challenges facing dentists and technicians.

With these challenges comes the creation of exciting new products, and the Biofunctional Prosthetic System (BPS) is certainly one of these. Leca Dental is leading the way as one of the few laboratories in Scotland able to offer this product.

Manager of Leca’s private department, Chris McMahon, has undergone extensive training on this type of specialist denture and has plenty of practical experience using it. Here, he talks us through one of his most recent BPS denture cases. Can you please tell us a little about the BPS?

Chris McMahon (CM): The BPS produces world class, aesthetic dentures of outstanding quality, perfect fit and exceptional comfort. As far as I’m aware they’re the most superior dentures in the market. We have found the success of the BPS relies heavily on the close relationship between our laboratory and the dentist, allowing us to create a natural looking denture. Can you tell us a bit about the patient and what it was that they required?

CM: After years of living with ill-fitting and sometimes uncomfortable dentures, the patient decided to take some action and enlisted the help of one of Glasgow’s most exclusive dental practices. Why did you and the dentist decide that a BPS denture was the best option?

CM: In this case, a complete denture was required and after much consideration and discussions through various options, it was decided that a BPS denture would be the most suitable due to the function, alignment and accuracy that could be achieved. What was used to create this denture?

CM: In this case we used Ivoclar Phonares denture teeth, which if you haven’t heard before, are the Rolls Royce of teeth! They are extremely natural looking and refract light like natural tooth enamel. 

Ivoclar Phonares denture teeth are without doubt one of the most superior teeth available in the UK, which is why the dentist was so eager to use them. Can you talk us through the working stages that it took to create this denture?

CM: To create a superior prosthetic BPS denture, there are more stages to the process than that of a conventional denture, which means it does require more time in the laboratory. It also calls for additional appointments in the dental surgery to ensure that the denture functions omnidirectional.   

After the initial consultation appointment at the dental surgery, the dentist took impressions of the patients’ mouth using the BPS impression technique to allow us to create the primary cast. These were then sent back to the dentist allowing them to do the outlining of the special tray on the primary cast. We then received the case back from the dentist and began the fabrication of the special trays in our laboratory.

Once complete, the dentist then checked the functioning of the trays in the patients’ mouth and then used a Gnathometer. Back at the lab, we then set this up in a stratos articulator using Ivoclar Phonares teeth and finish the denture using the Ivobase System, which improves the fit and strength of a denture. Was the dentist and patient happy with the outcome?

CM: We received some fantastic feedback from the dentist who said the patient was delighted with the finished product, which far exceeded her expectations.  I think in this career when we aren’t always patient facing it can be easy to forget that there is a customer at the end of it. What do you think sets this apart from other systems used?

CM: The superior quality of the dentures made using the BPS is incomparable to anything I’ve worked with before and I look forward to working on even more cases in the near future. As one of the only laboratories in Scotland being able to offer this product, I think it demonstrates our ongoing commitment to embracing and driving forward the latest advancements in dentistry.
