SELECTION

COMPARISION OF DENTURE TOOTH MOLDS AND OCCLUSAL CONCEPTS

TOOTH MOLD OCCLUSAL CONCEPT ADVANTAGE DISADVANTAGE

20 or 30-degree cusp teeth

• Centric jaw record, face bow, protrusive records to semi-adjustable.

• Set upper anterior and posterior teeth, then lowers to cross-arch contact or “balanced-occlusion”

• Reported slightly more efficient in chewing tests

• Posteriors appears more natural

• Most time and complexity of records

• Limitations of anterior tooth positions

• Restriction of posterior tooth positions to that allowed by Cuspal anatomy

Monoplane 0-degree

• Centric jaw record only• Simple articulator• Set 12 anterior teeth with

Overjet but no overbite• Set lower teeth in flat plane to

middle of retromolar pad• Set upper to match; no

attempt on contact on excursions

• Simplest of all recordings• Simplest articulators• Quick arrangement of

teeth• Wide range of posterior

tooth positions possible• No lateral stresses on

mucosa with parafunction• Easier for patients with

uncoordinated closures

• Flat premolars may appears less esthetic

• Reported as less aesthetics

• Anterior esthetics need more Overjet and no overbite

SELECTION

COMPARISION OF DENTURE TOOTH MOLDS AND OCCLUSAL CONCEPTS

TOOTH MOLD OCCLUSAL CONCEPT ADVANTAGE DISADVANTAGE

Flat teeth with compensating curve or second molar ramp

Centric jaw record Semi-adjustable articulator Anterior teeth with Overjet

and slight overbite Posterior set to contact on at

least 1 point on non-working or balancing side

Simple to set up; allows for more esthetic overlap of anterior teeth

The posterior point contact maintain denture base stability on excursion or parafunction

Slightly more laboratory set up

Premolars appear flat if visible

Combination or “lingualized” occlusion

Centric jaw record Monoplane lower posterior

teeth set to retromolar pad Anatomic upper posterior

teeth set with only lingual, not buccal cusp touching

Upper premolars appear natural

Some range of posterior tooth position allowed

Reported slightly better chewing than monoplane

Some grinding needed to create upper cusp tip/lower fossa contacts
