Here’s a quick and clear summary of indications for each prosthodontic treatment:
- Fixed Partial Denture (FPD) – “Bridge”
Indications:
One or more missing teeth with healthy abutments on both sides. Short span edentulous space. Strong periodontal support of abutment teeth. Patient prefers non-removable prosthesis. Good oral hygiene and motivation.
- Removable Partial Denture (RPD)
Indications:
Multiple areas of missing teeth with long-span edentulous areas.
No suitable abutments for FPD then consider rpd
Financial limitations (more economical than FPD).
Interim or transitional prosthesis.
When FPD is contraindicated due to periodontal issues.
Patient not suitable for implants.
- Complete Denture (CD)
Indications:
Complete edentulous maxillary or mandibular arch.
Severe loss of remaining teeth requiring full extraction.
Patient desires or requires complete replacement of all teeth.
Economic alternative to implant-supported prosthesis.

Kennedy's Classification¶
Kennedy classified partially edentulous arches and not the denture. The classification is positional or anatomical and conveys a picture of certain teeth and their relationships, but gives little information about the teeth present and their positional relationships.
Class I: Bilateral edentulous areas located posterior to the remaining natural teeth, i.e. there are two edentulous spaces located in the posterior region without any teeth posterior to it (Fig. 16.10).
Class II: Unilateral edentulous area located posterior to the remaining natural teeth, i.e. there is a single edentulous space located in the posterior region without any teeth posterior to it (Fig. 16.11).
Class III: Unilateral edentulous area with natural teeth anterior and posterior to it, i.e. this indicates a single edentulous area which does not cross the midline of the arch,with teeth present on both sides (anterior and posterior) of it (Fig. 16.12).
Class IV: Single, bilateral edentulous area located anterior to the remaining natural teeth. This is a single edentulous area, which crosses the midline of the arch, with remaining teeth present only posterior to it (Fig. 16.13).
Applegate modified the above classification based on the condition of the abutment to include two more additional groups:
Class V: Edentulous area bounded anteriorly and posteriorly by natural teeth but in which the anterior abutment(e.g. lateral incisor) is not suitable for support.It is basically a class III situation where the anterior abutment cannot be used for any support. Hence,it cannot be treated like a conventional class III edentulous space (Fig. 16.14).
Class VI: Edentulous area in which the teeth adjacent to the space are capable of total support of the required prosthesis. This denture hardly requires any tissue support.Most of the removable partial dentures are tooth tissue supported.
The following rules should be considered to classify partially edentulous arches based on Kennedy's classification. During the initial examination of the patient, if it is diagnosed that any teeth require extraction, it should be done prior to
