BDLoad® is a milling blank in which the dental arches are integrated in a functional, aesthetic set-up
The current integrated set-up concept of the dental arches follows that of lingualised occlusion. BDLoad® is characterised by harmonious positioning of the anterior and posterior teeth in eugnathic occlusion and optimal contact relationships.
The polymerised dental arches are made of the prefabricated Polystar® Selection EDITION anterior teeth and DeltaForm® posterior teeth by Merz Dental. These synthetic teeth have an impressive aesthetic effect as well as high abrasion resistance and can be furnished in different shades.
BDLoad® arches come in S, M and L sizes as well as in the jaw widths narrow, medium and wide with a set-up either to the 1st or 2nd molar for alignment according to the patient-specific alveolar ridge situation.
The BDLoad® as well as teeth are made of highly cross-linked PMMA. Compared to conventionally manufactured dentures, the material properties in terms of volume stability, tensile strength and a reduced monomer content of less than 1% are significantly improved as a result of the controlled polymerisation during industrial production of the BDLoad® and the additional tempering process. The BDLoad® has less allergenic potential compared to conventionally manufactured dentures.
The milling blank is furnished with an integrated zero point clamping system for positioning in the milling machine, which allows for clear, positionally accurate placement in different milling systems. In order to also restore large jaws as far as possible, the diameter of the BDLoad® was set to 113 mm.
|Residual monomer content||under 1% (low allergy potential)|
|Flexural strength||> 90 MPa (according to DIN EN ISO 20795-1)|
|Water absorption||> 32 μg/mm3 (according to DIN EN ISO 20795-1)|
Tooth setup with prefabricated teeth
The occlusion concept based on a positioning system according to Prof. Gerber entails lingualised occlusion of the dental arches with unilateral support. In addition, the contact relationships ensure the independent masticatory stability of the dentures.
The four-layer Polystar® Selection EDITION anterior teeth meet the high individuality requirements for high-quality dental prosthetics. The universal anterior tooth together with the semi-anatomical DeltaForm® posterior tooth offers a high aesthetic level along with a modern functional surface design.
The DeltaForm® posterior tooth with its specially designed lingualised chewing surfaces, characteristic abrasion facets and low cusp angle encompasses all the requirements of this full denture manufacturing concept.
The semi-anatomical chewing surfaces of the posterior teeth centre the line of force on the alveolar ridge, this avoiding horizontal force. In order to ensure unilateral support during dynamic chewing movements, they feature additional bilateral balance and result in „more gentle“ centring through the mortar-pestle principle.
