The superior boarder of the bar should be atleast 3mm from the free gingival margin of the teeth

Back 25

Sublingual bar

Front 26

Excessive blockout of interproximal undercuts would be required

Back 26

Mand. Lingual bar with continuous bar

Front 27

When wide diastema exist between mandibular anterior teeth and a linguoplate would objectionably display metal inna frontal view

Back 27

Lingual bar with continuous bar

Front 28

When lingual plate or sublingual bar is otherwise indicated but the axial alignment of the anterior teeth is such that excessive blockout of interproximal undercuts would be required

Back 28

Cingulum bar

Front 29

Contraindication of use: anterior teeth severely tilted to the lingual

Back 29

Cingulum bar

Front 30

When wide diastema exist

Back 30

Cingulum bar

Front 31

When the lingual inclinations of remaining mandibular premolar and incisor teeth cannot be corrected preventing placement of a conventional lingual bar connector

Back 31

Labial bar

Front 32

When severe lingual tori cannot be removed and prevent the use of a lingual bar or lingual plate major connector

Back 32

Labial bar

Front 33

When severe and abrupt lingual tissue undercuts make it impractical to use a lingual bar or a lingual plate major connector

Back 33

Labial bar

Front 34

C&L: superior border tapered to soft tissue

Back 34

Mand. Lingual bar

Front 35

Bilateral edentulous spaces of short span in an tooth supported restoration

Back 35

Front 36

Strap should be 8mm wide or approx as the combined width of a max premolar and first molar

Back 36

Single palatal strap type

Front 37

Class I partially edentulous arches with residual ridges that have undergone littlevertical resorption and will lend excellent support

Back 37

C&L: inferior border located at the ascertained height of the alveolar lingual sulcus when the pt. Tongue is slightly elevated

Back 48

Mand. Lingual bar

Front 49

Indication for use: when alveolar lingual sulcus so closely approximates the lingual gingival crevices that adequate width a rigid lingual bar does not exist

Back 49

Mandibular linguoplate

Front 50

Class I arch have undergone such vertical resorption that they will offer only minimal resistance to horizontal rotations of the denture through its bases

Back 50

Mand. Linguoplate

Front 51

For using periodontally weakened teeth in group function to furnish support to the prosthesis and to help resist horizontal rotation of the distal extension type of denture
