Model analysis

The following reference points are deter-mined by analysing the model:

1] Position of the canines:Determine the first large pair of rugae;the centre of the labial surface of themaxillary canine is positioned at a distanceof 9mm.

2] Contact point of the two central incisors:The labial surface of the central incisors islocated at a distance of 7mm from thecentre of the incisive papilla.

Based on the length of the curve passingthrough these three reference points, youcan select an anterior set of appropriatewidth by means of the tooth mould chart.

FormSelector

The PHONARES FormSelector allows fast, easyand targeted selection of the appropriateanterior tooth mould.

Step 1 Determine the interalar width ofthe nose with the help of theFacialMeter. Select an appropria-tely sized tooth mould from theINTER-ALA table.

Step 2 Select the desired tooth form, softor bold, in line with the shape ofthe patient’s face.

Step 3 Select the appropriate age groupof the teeth according to the inci-sal wear and facial curvaturecharacteristics of the SR PHONA-RES NHC teeth.

The FormSelector is based on the relationshipbetween the interalar width of the nose andthe width of the maxillary anterior arch.Alongside a few other selection criteria, thecorrelation between the interalar width andwidth of the anterior arch is based on thestrongest scientific evidence amongstrelevant measurements.Mavroskoufis et al.

The design of the anterior archsignificantly influences the facialexpression of the patient.

The characteristics of each individualare unique; the reference linesdetermined during the modelanalysis phase can be used as meaninitial guides for the setup of theSR PHONARES NHC denture teeth.

The BPS manual provides adetailed description of the modelanalysis and anterior tooth setupmethod.

The wax try-in of the setup to verify the phoneticand functional virtues represents the definitive oralreference.

The SR PHONARES anterior teeth are suitable forvarious anterior setup designs, ranging from con-ventional to highly individualized. Consequently,the anterior teeth support the natural estheticappearance of the individual patient.

The incisive papilla provides a reliablereference point for the setup of theanterior teeth because of itstransverse and sagittal resistance towear.

The position of the canine teeth plays a decisiverole in the creation of a harmonious facial expres-sion. In the dental arch, the canines are positionedin the area of the first large pair of palatine rugae,with the labial surface of the maxillary caninesbeing placed at a distance of approx. 9mm. Thevertical orientation of the canines significantly in-fluences the curvature of the smile line.

After the canines have been positioned, thelateral incisors are placed in the gap between thecentral incisors and the canines. By slightlyrotating or interlocking the lateral incisors, highlyindividualized effects can be achieved.

Starting with the canines, the mandibular incisorsare set up in a vertical and sagittal distance thatcorresponds with the respective occlusal positionand bite situation.

It can be checked if the smile line runs symmetricalto the arch of the lower lip by transferring themarkings on the bite rim to a silicone key.

In a normal bite situation, the central incisors arealigned with the incisive papilla by positioning thelabial surface approx. 7mm towards the front fromthe centre of the incisive papilla.

The raphe median plane determines the symmetryaxis of the anterior tooth setup in the upper jaw.The course of the incisal edges of the centralincisor teeth is determined by half the height ofthe overall vertical dimension plus 2mm of overlap.

The wide design of the tooth necks ofSR PHONARES NHC teeth permit metal structuresand abutments to be reliably covered.

The Set & Fit design is based on convex distalmargins and concave mesial proximal surfaces,which interlock like a joint. The Set & Fit designensures the natural closure of interdental spaces.

No matter which setup method is used, blacktriangles are prevented due to the widelydimensioned cervical portion of the teeth. Con-sequently, dental technicians can enjoy completefreedom in the design of the gingival portion (i.e.“pink esthetics”) of the dentures.

The SR PHONARES NHC anteriorteeth represent a new generationof denture teeth, offering lifelikeesthetics in prosthetics.

Typ NHC

The SR PHONARESTyp NHC teeth continue the 40-year-old success story of the Orthotyp toothmoulds.

The Ivoclar Vivadent "Typ" tooth lines are basedon the principle of the group function of thelatero- and mediotrusion side according toDr. Strack.

The SR PHONARESTyp teeth are set up inaccordance with a normal bite situation in a one-to-two-tooth relation. Consequently, the primarycontacts in the centric position are located in thecentral fossae of the mandible and on themarginal ridges.

The SR PHONARESTyp NHC teeth are supported bya secondary contact area on the buccal cusps inthe mandible.

The first step involves aligning the template withthe height of the distal third of the retromolar padin the posterior region and with the height of thedistal angle of the mandibular canines in theanterior region. For the setup of theSR PHONARESTyp NHC teeth according to theBPS principles, the following criteria have to beobserved:

The use of a template ensures that the sagittal(Spee) and transverse (Wilson) compensatingcurves are taken into account. The compensatingcurves of the natural dentition are essential forbilateral balanced group guidance.

Seen from the occlusal side, the central fossae ofthe mandibular posterior teeth are positioned overthe crest of the alveolar ridge. The lingual borderof the posterior tooth setup is defined by Pound'sline (Pound's line extends from the mesial cornerof the mandibular canine to the lingual border ofthe trigonum on the same side).

The lines on the template facilitate the symmetricalsetup of posterior teeth.The setup of the mandibular teeth begins with thefirst premolars, followed by the second premolars,first molars and second molars.

Contact of the template table with the buccalcusp tips and mesio-lingual cusps must be ensured.

In the process, the vertical axes of the first andsecond molars are automatically aligned. Viewedfrom the buccal side, the axes of the first andsecond premolars have to be aligned perpendicularto the template.

The SR PHONARESTyp teeth were developed inaccordance with the principles of the BiofunctionalProsthetic System (BPS). The lower posterior teethare set up with the help of a setup template. Inline with the above notes on model orientation, a3D, 2½D, or 2D template is used.

• The mesio-palatal working cusp engages withthe central fossa of the mandibular first molar.

• The disto-palatal working cusp has marginalridge contacts with its antagonist.

• Viewed from the buccal side, the mesio-buccalcusp of the maxillary first molar points towardsthe mesio-buccal fissure of its antagonist. This isa typical characteristic of a conventional bitewith normal intercuspation.

The maxillary teeth can now be aligned with themandibular teeth in a 1-tooth-to-2-tooth relation-ship in optimum intercuspation.

Relatively extensive guiding surfaces are desirableto ensure a balanced occlusion within thefunctional range; the following grinding-in guide-lines should be observed:

• The centric contacts must no longer be ground.• Working side (laterotrusion): mesio-buccal cuspsin the maxilla, lingual cusps in the mandible

• Balancing side (mediotrusion): mesio-buccalcusps in the mandible

• Protrusion disto-buccal cusps in the maxilla,mesio-buccal cusps in the mandible

• Retrusion: mesio-buccal cusps in the maxilla,disto-buccal cusps in the mandible.

The incisal edges of the anterior teeth should beground from the palatal side in the maxilla andfrom the lingual side in the mandible, inaccordance with the wear pattern occurring inthe natural dentition.

In complete denture prosthetics, no majoradjustments by grinding are made prior tocreating the resin base. If the packing or cold-pouring technique is used to produce the denturebase, an increase in vertical dimension has to beexpected. With the SR Ivocap Denture ProcessingSystem, however, an increase in the verticaldimension is prevented from the very start.

Increased vertical dimensions should be correctedprior to removing the polymerized dentures fromthe model whilst the centric lock is engaged. Thefollowing guidelines should be observed:

• Do not grind the working cusps.• Reduce premature contacts in the antagonistfossa.

After the height of the occlusal position has beenadjusted, all the centric contacts have to be inplace as determined by the setup.

Lingual NHC

The basic principles of lingualized occlusion havebeen incorporated into the design of theSR PHONARESLingual NHC denture teeth.

The centric contacts with the maxillary palatalcusps are centred in the mandibular fossae. Thebuccal cusps are set up out of contact with eachother. An additional buccal contact relation canbe established on the first premolars if this isdesirable from the point of view of esthetics.

Hence, the SR PhonaresLingual NHC teethensure a particularly pronounced buccal supportmechanism.

In the mandible, the SR PHONARESTyp NHC teethcan be set up in either one of two versions: setupwithout curve of Wilson or setup with curve ofWilson.

Since all working contacts are lingualized and thebuccal surfaces do not occlude, there is somescope for variation in the degree of the curve ofWilson.

The following criteria should be considered whensetting up SR PHONARESLingual NHC teeth:

The SR PHONARESLingual teeth were developed inaccordance with the principles of the BiofunctionalProsthetic System (BPS). The posterior teeth are setup with the help of a setup template.

In line with the above notes on model orientation,a 3D, 2½D, or 2D template is used. The first stepinvolves aligning the template with the height ofthe distal third of the retromolar pad in theposterior region and with the height of the distalangle of the mandibular canines in the anteriorregion.

The characteristic of this setup method is the factthat the buccal cusps do not have any contactwith the template. It is necessary to ensure thatthe buccal and lingual cusp tips are on the sameplane.

The central fossae of the mandibular posteriorteeth are positioned over the crest of the alveolarridge. The mandibular posteriors must not extendbeyond Pound's line on the lingual aspect.

The contacts with the template are concentratedon the lingual cusp tips to achieve a setup thatonly has a sagittal compensating curve. Viewedfrom the buccal side, the vertical axes of theposterior teeth have to be aligned perpendicularto the template. To achieve a horizontal alignmentof the cusp tips on the first premolar, the buccalcusp may be brought into contact with thetemplate.

If the curve of Wilson is taken into account in thesetup of the SR PHONARESLingual NHC teeth,contacts between the template and the buccaland lingual cusps are required.

Force vector

The periodontium absorbs some of the stress towhich dental replacements on natural abutmentsare exposed.

However, in the case of implant-retained dentalprostheses, the stress is not cushioned by theperiodontal ligament. The proprioceptive functionis limited and the actual masticatory forces areconsiderably higher in edentulous patients withimplant-borne prostheses than in patients withnatural abutments.

Tooth replacements are constantly exposed toshear, compressive and tensile forces. However,compressive forces affect the implant interfaceconsiderably less than tensile or shear forces dueto torque.

The SR PHONARESLingual NHC teeth areparticularly suitable for use in implant prosthetics.

• It is possible to direct the masticatory forces tothe implant by a force vector in the longitudinalaxis, which results in a reduction of the shearand tensile forces.

• The occlusal design of the mandibularSR PHONARESLingual NHC teeth is characterizedby a flat morphology, reduced marginal ridges,and freeway space in the centric position. Highlateral loads are thus avoided.

• The specially developed nano-hybrid compositematerial offers outstanding wear resistance.

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 causewhite discolouration.

Grinding-in should be carried out with cross-cuttungsten carbide burs with adequately shapedattachments. Final polishing with UniversalPolishing Paste and a goat's hair brush providesthe surface of the NHC teeth with a finish thatensures a long service life.

Conditioning of the SR PHONARES teeth is re-commended before processing the denture base.Basically, the tooth surfaces should be clean andthe palatal, basal, and cervical areas should be

slightly roughened. The brochure “NHC ProcessingGuidelines” provides detailed instructions onbonding SR PHONARES teeth to denture basematerials.

The SR Ivocap System is an idealhigh-quality supplement to theSR PHONARES line of denture teeth.

Accuracy of fit is decisive in achieving high-qualitydental prostheses. We recommend using theSR Ivocap injection system to process the denturebase. During controlled heat-pressure polymeriza-tion, the material shrinkage is compensated by theflow of the material.

The SR Ivocap System eliminates the spherical di-mensional changes in conjunction with the con-ventional polymerization methods identified byProf. Dr. K.H. Körber (Kiel, Germany).
