Maxillary Maxillary Single Single Dentures Dentures

 More More common common  Teeth Teeth usually usually lost lost before before their their mandibular mandibular antagonists antagonists

Avoid Avoid aa Single Single Denture Denture Against Against Anterior Anterior Teeth Teeth Alone Alone  Resorption Resorption  Loosening Loosening  Fracture Fracture  Combination CombinationSyndrome Syndrome

Avoid Avoid aa Single Single Denture Denture Against Against Anterior Anterior Teeth Teeth Alone Alone  Fabricate Fabricate aa RPD RPD for for Stress Stress Distribution Distribution  Make Make CD CD & & RPD RPD at at the the same same time time –– Ensures Ensures optimal optimal occlusion occlusion

Occlusion Occlusion Rims Rims  Use Use to to establish establish OVD, OVD, NOT NOT Incisal Incisal Display Display  Overbite Overbite will will be be incorporated incorporated when when anterior anterior teeth teeth are are set, set, lengthening lengthening incisal incisal edges edges

Occlusion Occlusion Rims Rims  Flat Flat Surface Surface for for Opposing Opposing Teeth Teeth

–– No No inclines inclines –– If If steps steps in in occlusal occlusal plane, plane, provide provide flat flat areas areas for for opposing opposing natural natural teeth teeth

Maxillo-Mandibular Maxillo-Mandibular Relations Relations  Occlusion Occlusion Rims Rims on on RPD RPD framework framework  Opposes Opposes CD CD Rims Rims  Centric Centric and and eccentric eccentric records records with with Alluwax Alluwax  Optimizes Optimizes occlusion occlusion

Maxillo-Mandibular Maxillo-Mandibular Relations Relations  Crowns Crowns or or bridges bridges should should be be waxed waxed up up against against the the CD CD tooth tooth setup setup  Optimizes Optimizes occlusion occlusion  Ensures, Ensures, changes changes can can be be made made

Maxillo Maxillo -- Mandibular Mandibular Relations Relations  Centric Centric Registration Registration

–– CUD CUD usually usually stable stable –– Extraoral Extraoral hand hand position position ifif opposing opposing natural natural dentition dentition (less (less obtrusive) obtrusive)

Setting Setting Anterior Anterior Teeth Teeth  More More difficult difficult

–– Setting Setting for for esthetics esthetics may may produce produce excessive excessive overbite overbite with with natural natural teeth teeth –– Decreases Decreases stability stability –– Compromised Compromised position, position, used used to to balance balance need need for for esthetics esthetics & & function function

Posterior Posterior Denture Denture Teeth Teeth  Requires Requires more more adjustment adjustment to to obtain obtain stable stable centric centric contacts contacts

–– Denture Denture teeth teeth will will not not normally normally articulate articulate well well with with natural natural dentition dentition –– Pinpoint Pinpoint contacts/inclines, contacts/inclines, etc. etc.

Increase Increase incisal incisal pin pin 1mm 1mm Set Set posterior posterior teeth teeth Let Let wax wax harden harden Return Return pin pin to to original original position position  Adjust Adjust occlusion occlusion until until pin pin touches touches table table

Cast Cast Metal Metal Denture Denture Base Base  Use Use ifif denture denture fractures fractures repeatedly repeatedly  Usual Usual causes: causes:

–– Heavy Heavy forces forces from from natural natural teeth teeth –– Occlusal Occlusal contacts contacts on on inclines inclines –– Impingement Impingement on on aa bony bony midline midline •• flexing flexingof ofthe thedenture denture

Denture Denture Teeth Teeth Wear Wear   

More More rapid rapid against against natural natural teeth teeth More More frequent frequent recalls recalls Adjust Adjust occlusion occlusion to to prevent prevent changes changes in in stress stress distribution distribution

Denture Denture Teeth Teeth Wear Wear More More Rapidly Rapidly  Never Never use use porcelain porcelain denture denture teeth teeth

–– Severe Severe attrition attrition of of natural natural teeth teeth –– Prefer Prefer denture denture teeth teeth to to wear wear
