Different types of connectors used for teeth.

1. Major Maxillary Connectors
DEFINITION:
It is a component of partial denture that connects parts of partial removable prosthesis at one side
of arch with those on opposite side.
Major Maxillary Connectors
TYPES:
Six basic types of major maxillary connectors are:
1. SINGLE PALATAL BAR: its component is less than 8mm in width is referred to as a
bar.
Indication:
 Limited to replacing one or two teeth on each side of arch.
Contraindication:
 In distal extension situation
 when anterior teeth are to be replace

2. 2. SINGLE PALATAL STRAP: It consists of a wide thin barel of metal that crosses the
palate in an unobtrusive manner.
Indication:
 In CLASS III situations.
 Need for palatal support is minimal.
Contraindication:
 Anterior replacements with distal extension bases.
3. U-SHAPED PALATAL CONNECTOR: It consists of thin band of metal running along
posterior teeth and extending onto the palatal tissues for 6-8mm.
Indication:
 Can be in case of a large inoperable tori
 When several anterior teeth are to be replaced.
4. ANTERIOR-POSTERIOR PALATAL BAR: The flat anterior bar is narrower than the
palatal strap.
Indication:
 When support is not a major consideration and when the anterior and posterior abutments
are widely separated.
 Presence of torus palatinus.
Contraindication:
 In reduced periodontal support of the remaining teeth that necessitates additional support
from the palate.

3. 5. COMBINATION ANTERIOR AND POSTERIORPALATAL STRAP-TYPE
CONNECTOR: A posterior palatal strap should be flat and a minimum of 8 mm wide.
Indication:
 Kennedy’s Class I and CLASS II arches.
 CLASS II modifications I arches.
 Class IV arches.
Contraindication:
 In addition, the extensive length of borders may cause discomfort to the tongue.
6. PALATAL PLATE-TYPE CONNECTOR: The full palate connector should be thin,
with the natural anatomy of the palate reproduced.
Indication:
 CLASS I AND CLASS II arches.
 Cleft palate patients.
Contraindication:
 Presence of tori which cannot be surgically removed a full palatal coverage cannot be
given.
