NHC component Function Main advantage

UDMA (urethanedimethacrylate)

Matrix The UDMA matrix features a high degree of cross-linking. The material structure offers high stability andhigh resistance to chemical attacks.

High-density silanizedSiO2

Filler 1 Inorganic fillers stiffen the matrix and increase thematerial’s hardness and resistance to abrasion. They alsooptimize the material’s refractive index and thereforeenhance the natural shade effect and opalescence.

Silanized SiO2nano-particles

Filler 2 Nanoscale surface-modified inorganic particles reinforcethe composite structure. The nanoscale propertiesarising from these particles are responsible for theformation of homogeneous contact surfaces. As aconsequence, the material is very kind to opposingtooth structure.

Inorganically filledUDMA polymer

Filler 3(Iso-filler)

Matrix-based pre-polymer particles help reducepolymerization shrinkage.

PMMA clusters Inclusions The inclusion of PMMA clusters in the compositestructure reduces the affinity for plaque anddiscoloration.

Macro FillersThe NHC material is a composite which consists of a urethane dimethacrylate matrix with inorganic fillers,iso-fillers (prepolymer) and PMMA clusters embedded in the structure. The combination promotes optical,strength and bonding characteristics.

Anterior Mould Artistry

SR PHONARES anterior teeth embody theessence of natural dentition. Each mould hasbeen sculpted to deliver the ultimate lifelikeresult. The texture of the labial surfacesreproduces the mild ripple effect (perikymata)seen on natural enamel surfaces. The uniqueNano-Hybrid Composite resin chemistrycreates an unpareled true-to-nature vitality.

The maxillary anterior moulds were designed by making logical variations ofthese principles of tooth morphology in order to express individual patientcharacteristics (soft & bold) and age (youthful, universal, mature).



A N T E R I O R MOU L D S E L E C T I O N

There are basically six maxillary anterior moulds. Three are designed with “soft” characteristicsand three are designed with “bold” characteristics. Each soft and bold category is furthersubdivided into three age groups (youthful, universal, mature).

The six moulds are in three sizes.(small, medium, large) delivering a total of 18 maxillary anterior moulds.

In the Centric position most conventional denture occlusal schemes suggest simultaneousposterior occlusal contacts with the elimination of anterior tooth contacts.

• The rationale for the elimination of the anterior tooth contacts is based on the premise thatanterior contacts would destabilize the dentures.

1.5mm of horizontal overlap (over jet)• However, the degree of vertical overlap and horizontal overlap is controlled by the degree ofcusp angles of the posterior teeth selected and the steepness of the antero-posteriorcompensation curve (curve of Spee). These two factors determine how much vertical overlapcan be created and how much horizontal overlap is necessary to prevent the anterior teethfrom contacting in protrusive and lateral excursive movements.

In eccentric positions most conventional denture occlusal schemes suggest simultaneousbilateral posterior occlusal contacts with the elimination of anterior tooth contacts. Eccentricanterior tooth contacts can destabilize the prostheses during function. Therefore anteriorguidance is not recommended for denture occlusion.

I M P L A N T S U P P O R T E D D E N T U R E S

Anterior guidance is also not recommended for implant supported restorations. Patientsrestored with implant supported restorations are capable of exerting significantly greater forcesand lack the necessary proprioceptive feedback (periodeontal membrane) to correctly monitorthese forces. Therefore anterior guidance may have the potential for excessive wear and orbreakage of the anterior denture teeth.

• Single maxillary palatal cusp contact• Non-functional maxillary buccal cusps• Uncomplicated mandibular central fossa

Maxillary Palatal Cusp ContactsEach maxillary tooth provides one palatal cusp thatwill function as a Centric holding stop and articulatesto the respective mandibular fossae. Note: the distal-palatal cusps of the maxillary 1st and 2nd molars arenon functional and therefore are not set in contact.

Non-Functional Maxillary Buccal CuspsThe maxillary buccal cusps are progressively elevatedand remain out of occlusion in Centric and Eccentriclateral jaw excursions. This provides support for thecheek and helps to prevent cheek biting. Anexception to this is the maxillary 1st premolar whereelevations of the buccal cusp may create anunappealing relationship with the maxillary canine.Therefore, an additional buccal contact is suggestedfor the maxillary 1st premolar.

Uncomplicated Mandibular Central FossaThe uncomplicated mandibular central fossa allowssome degree of forgiveness since the teeth are notrestricted to being set in one intercuspal position.

Selection Guides

The PHONARES FormSelector allows fast, easy andtargeted selection of the appropriate anterior toothmould. The FormSelector is based on the relationshipbetween the interalar width of the nose and the widthof the maxillary anterior teeth.

Although the shades follow the Classic Vitapan A-Dshade system it is recommended to use thePHONARES shade guide for more accurate results dueto the simple fact that the SR PHONARES shade guideis fabricated from the same materials and layeringprocess as the original SR PHONARES teeth. Shadeguides made of dissimilar materials may giveinaccurate results due to the metamerism effect indifferent light sources. For best results shadeselection should be performed on the patient underdefined light conditions (5500K color temperature) orin daylight.

Step 1Select an appropriately sized tooth mould(small, medium, large) with the aid of the“Facial Meter” found within theFormSelector

Step 2Determine the desired tooth form (soft orbold) that would match the characteristicsof the patient

Step 3Select the age group (youthful, universal,mature) that would best suite the goals ofthe restoration

Ensure that surfaces are free of dust, moisture andgrease before conditioning them. For this purpose,each individual tooth should be cleaned with a steam

cleaner and all residual wax should be removed.When applying compressed air, make sure that thesystem is free of oil.

E X C E P T I O N S

If SR Phonares is bonded to a suitable C & Bcomposite, the use of SR Composiv® bonding agent isrequired to ensure an optimal bond.

Apply SR Composiv directly from the syringe onto the“bonding surface” and distribute to an even layerusing a spatula or disposable brush. Apply the

material in a layer thickness of at least 0.2 mm andno thicker than 0.5 mm. The working time is approx.3 minutes. SR Composiv can be polymerized in asuitable light-curing device.Please refer to the Instructions for Use of theindividual material/device for more detailed userinformation.

Roughen the bonding surfaces either with a cross-cuttungsten carbide bur or by abrasive blasting withAl2O3 (grit size: 50-100 µm) at a pressure of 1–2 bar(15–30 psi).

The tooth necks should also be roughened. Usecompressed air to remove residual abrasive dust.

If the SR Phonares teeth are bonded to a cold-curingdenture base material (e.g. ProBase® Cold), it isnecessary to apply mechanical retentions by grinding.The retentions are best performed with a round

spherical bur to avoid sharp edges. Undercuts can becreated by swivelling the bur head. Avoid excessiveheat build-up when grinding.

* Avoid breathing in grinding dust – use dust evacuation equipment and breathing protection.

After cleaning and roughening, wet the bondingsurfaces with monomer liquid (e.g. ProBase Coldmonomer) to allow the resin to swell andconsequently to strengthen the chemical bond. Use abrush to apply the monomer selectively. Next, allowthe monomer-wetted areas to react for approx. 3minutes.

Avoid contamination after the reaction time haselapsed.

Note:• After wetting with monomer, the teeth may nolonger be steam-cleaned.

Overheating should be prevented when finishingthe dentures. Polishing or cleaning agents con-taining solvents should not be used for cleaning.They may adversely affect the composite materialof the denture base and denture teeth and causediscoloration.

Adjusting-in should be carried out with cross-cuttungsten carbide bur. Final polishing withUniversal Polishing Paste and a goat's hair brush isrecommended for the surface of the NHC teeth.

Finishing / Polishing

It is recommended to use a carbide bur when grindingPhonares teeth. Use moderate speed to avoid excessiveheat build up.

The structural integrity of the tooth must be preserved. It issuggested that a minimal thickness be maintained.

ANTERIOR TEETH:• grinding of tooth material → minimum 1.5mm

POSTERIOR TEETH:• in the central fossa → minimum 2.0mm• in the cusp → minimum 2.5mm

For implant retained hybrid restorations it is again notrecommended to drill holes for retentions in the teeth oraccess holes for implant retained hybrid constructions.
