Biofunctional Prosthetic System in Prosthodontics

ABSTRACT

Recent advances in removable prosthodontics include biofunctional prosthetic system (BPS), which closely replicates aesthetics, comfort, functional, and phonetic aspects of natural dentition. The BPS system is a standardized system for the fabrication of high quality removable / complete dentures. It outstandingly fulfills the functional and aesthetic demands of patients. BPS precision dentures are the result of a coordinated system of products, instruments, set-up techniques and training which are all available exclusively to certified BPS clinics.
The goal for BPS dentures is to provide what is best for patients using the instrumentation, training and materials necessary to create the highest quality denture available.

INTRODUCTION

The main aim of treating complete denture patients is to reinstate normal contour comfort form function and to preserve the residual ridge. Although conventional dentures satisfies maximum patients but few patients face discomfort during mastication and other problems including insufficient stability, retention, function and pain and sometimes the resulting pain increases to such an extent that it hinders in mastication and the confidence of the patient decreases
The unattractive facial appearance, difficulties with speech and mastication creates psychological effects on the patients and the final outcome of the denture becomes unsatisfactory.
Nowadays, the most advanced method used is the biofunctional prosthetic system, which focus-es on bilateral balanced articulation.⁵ Biofunctional prosthetic system (BPS) is also called “biogenic” or “bio¬functional”, because of the ability to construct dentures, which truly resemble these natural elements they substitute as well as fulfilling aesthetics, and functional and phonetic demands of the patient.⁵
The BPS system is intended to negate the shortcomings of conventional complete denture techniques.

BPS SYSTEM

The system employs a combination of standardized impression making procedures, a unique method of recording maxillo-mandibular relationship, teeth arrangement, and denture fab-ricationwith minimal number of patient’s visits. The border molding and impression making was controlled by the patient’s functional composition, hence yielding denture bases that were extremely comfortable in use. This technique presents ideal form, function, and aesthetics in complete denture prosthesis, since it is based on multidisciplinary effort and methodical approach.⁹ Molds are made using plaster and stone which is a replica of the gums. The wax replica denture is boiled out, and a special high Impact Acrylic is forced into the molds at 6 bar continuously until the acrylic is cured because the pink part of your denture is under 6 bar pressure, this gives a superior bond to the artificial teeth and because we have a replica of your gums creates a far better fit. This is the result of the careful scientific study at the Ivoclar factory from the past 30 years.
Ivocap Injection – can create a much denser and stronger denture as the acrylic under so much pressure packs the molecules much thicker together making the acrylic much harder. We notice this when trimming and polishing the dentures, makes it easier to clean and stain far less providing to follow the cleaning instructions.

PROCEDURE FOR MAKING A BPS DENTURE

Conventional methods of processing dentures result in shrinkage of the denture base. The denture wearer, this means a denture that doesn’t fit securely and gives sore spots. In the Biofunctional Prosthetic System, state-of-the-art equipment is used to form the denture base.
After making the impression facebow transfer is done and in some cases gnathometer is used Stratos Articulator is used for transferring the facebow record, and unique 3D set up the jig to position teeth for superior balance and function The denture is processed using IVOCAP continuous injection into the molds which results in better tooth bond denser pink acrylic, better fit to the gums and absorbs fewer stains and bacteria. Injection moulding and polymerization are performed by the injector in an automated process. The chemical shrinkage of the material is fully compensated during the polymerization process due to the patented thermal management of the flask and the heating system. This allows the fabrication of high-precision denture bases offering unparalleled accuracy of fit.
The injection technology used in the IvoBase Injection system results in a denture that will provide you with the best fit possible and superior results in removable dental prosthetics.
Tooth Selection in this system is done to match the size and skin tone appropriate premium P E Ivoclar teeth with the composite layer with advanced layering technique is used to create alive natural-looking translucent teeth which does not wear. Premium SR Phonares II and SR Vivodent SPE denture teeth are used as part of the Biofunctional Prosthetic System, both of which mimic natural teeth.
SR Phonares II have been designed to match the age and characteristics of the individual patient. The tooth moulds are available with “soft” and “bold” characteristics. Each soft and bold category is further subdivided into the three age groups – youthful, universal and mature.
SR Phonares II is distinguished by a high-quality surface texture that endows the tooth moulds with a true-to-nature vitality. The proximal surfaces are designed to tightly fit together, enhancing the “white aesthetics” of the restoration. The teeth feature a well-balanced relationship of translucency, opalescence and fluorescence. Precision crafted with a nano-hybrid composite, these teeth are characterised by high toughness, resistance to wear, tolerance and durability.
Teeth are set and tried in the mouth, which can be adjusted to give that just perfect aesthetic appearance, personal character.
Gums are carved and copied to natural Gum Gingivae texture and contours with artificial rugae in the palate to help phonetics and characterization of the incisal edges is also done. It includes only two complementary adjustments.
BPS is a system of professional expertise and quality products and is considered to be the standard for aesthetics, comfort, fit and function when it comes to dentures

ADVANTAGES OF BPS DENTURES OVER CONVENTIONAL DENTURES

• BPS Dentures reproduce the functions of the natural teeth during mastication & speech to a very high extent.
• The patient will get a well fitting denture which is stable during functions like chewing, eating, & speaking because the processing of the denture is done by continuous injection moulding technique.
• Even harder foods can be consumed immediately after denture insertion. The usage of high quality teeth sets & the work in the articulator according to the BPS principles makes BPS dentures a masterpiece.
• BPS dentures have high fracture resistance and 25 years clinical approved material.

CONCLUSION

In this era where the patients aesthetic demands are sky high BPS system is a relief. The BPS system gives unmatched quality and comfort. But a good clinical and technical expertise is requiredTeeth radiate character attractiveness and liveliness and BPS provides patients with self confidence charisma and self assurance.
