These results were similar to those reported by Al-Jabrah19 who found that all edentulous patients aged between 45 to 82 years were affected by residual ridge
resorption (range between 2%-57%) with mean reduction to be approximately 20%.

atrophy in complete denture wearers and relationship with densitometric values of a cervical spine: a hierarchical regression analysis," Gerodontology, vol.
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.

in complete denture wearers: A mixed longitudinal study covering 25 years.
Posterior teeth should be placed on the residual ridge
and in balanced occlusion.
Understanding the cause can assist the practitioner in preventing further residual ridge
(Fig 4) Intraoral presentation included heavy plaque deposits, halitosis, bleeding gums, pus exudates from pockets, grade 3 mobility and resorbed residual ridges
. Presence of unerupted third molars was evident from bulbous tuberosities and was confirmed on radiograph.
Correlation between residual ridge
resorption and radiomorphometric indices.
A full thickness periosteal reflection exposes the underlying residual ridge
and lateral regions of the mandible.
Confounding variables in the study included age, sex and type of residual ridge
. In order to minimize the effects of these variables, matching technique was used.
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
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.
