Case description and design parameters

Case classification:
A single tooth-supported edentulous area; Class III

Support areas:
Tooth support: Terminal abutments; quadrilateral support plane formed by the terminal abutments of teeth 24, 28, 14, and 17
Occlusal rests: 14 and 24 (DO), 17 and 28 (MO)

Guide planes:
Tooth-supported: 24 (D), 28 (M)

Direct retainer:
Akers clasps; 14 and 24 (MB undercut), 17 and 28 (DB undercut)

If interocclusal space is insufficient, the clasp on tooth 14 may be omitted; in this case, only the occlusal rest (DO or MO) is used to support the major connector.

Reciprocation:
Reciprocating clasp arm

Indirect retainer:
Not required due to the absence of a distal extension base

Major connector:
Palatal strap

Minor connectors:
Elements connecting the clasps and artificial teeth to the major connector

Denture base and artificial teeth:
Tooth-supported base; metal-acrylic base and acrylic artificial teeth

Case classification:
Three tooth-supported edentulous areas; Class III Mod 2

Support areas:
Tooth support: Quadrilateral support plane formed by the terminal abutments of teeth 23, 27, 14, and 17
Secondary abutments: 11, 13, and 14

Direct retainer:
Akers clasps: 14 (MB undercut), 17 and 27 (DB undercut); gingival clasp: 23 (MB undercut)

Reciprocation:
Proximal plate and cingulum rest: 23; reciprocating clasp arms: 14, 17, and 27

Indirect retainer:
Not required due to the absence of a distal extension base

Major connector:
U-shaped plate

Minor connectors:
Elements connecting the clasps and artificial teeth to the major connector

Denture base and artificial teeth:
Tooth-supported base; metal-acrylic base with acrylic artificial teeth and facing tooth
