Mandibular residual ridge
shape and the masticatory ability in complete denture wearers.
There are numerous studies on the prevalence of dentate arches in different populations and malocclusion types, (18, 28-32) but the studies on residual ridge
shape are scarce.
Atwood DA Some clinical factors related to the rate of resorption of residual ridges
Large residual ridges
provide better support and stability for the denture base than those which are relatively resorbed.
Correlation between residual ridge
resorption and radiomorphometric indices.
Extensive volume of the denture base material in prosthesis provided to patients with large maxillofacial defects or severe residual ridge
resorption is always a challenge to prosthodontists.
A full thickness periosteal reflection exposes the underlying residual ridge
and lateral regions of the mandible.
Significant disadvantages of metal base dentures are that they often irritate the underlying alveolar ridge and are difficult to reline and adjust Massad introduced a metal base denture with a resilient liner to manage the severely resorbed mandibular residual ridge
Its convex tissue surface resides in a soft tissue depression or hollow in the residual ridge
, which makes it appears that a tooth is literally emerging from the gingiva.
An anteroposterior strap major connector was designed for the maxillary arch, with lattice shaped minor connectors over the residual ridge
and clasp assemblies on 16, 14, 23-25.
A questionnaire was filled in by the principal investigator containing questions regarding extent and location of edentulous areas, condition of the abutment teeth and occlusion of the remaining teeth, residual ridge
status and conditions creating a guarded prognosis to determine the PDI class of each patient.
These may be due to a narrower, more constricted residual ridge
as resorption progresses, decreased supporting tissues, and a resultant large restorative space between the maxillary residual ridge
and opposing mandibular teeth (1).
