“…The basic factors' regarding resorptive changes of Residual Ridges under complete denture prosthesis were reviewed through the years and the factors that were explained According to author the factors expressed will have their own pros and cons, the legible use of clinical experience, laboratory protocols and materials will fetch food results and lessens RRR. 13 A revolutionary approachable study on RRR with the help of panoramic radiographs by Wical and Swoope, which was itself called a method, 11 they did extensive research and classified mandibular resorption. Osteoporosis produces more RRR.'…”

Aims and Objectives: Residual ridge resorption is perplexing problem for complete denture patients and so with the Prosthodontist.It is of multifactorial origin where it is termed as a chronic, progressive, irreversible and disabling disease. Several methods have been devised to measure the RRR like cephalometrics, dent contourographs, casts, photogrametrric method etc but the method described by Wical and Swoope is simple, useful method for arriving at gross estimate the amount of RRR. Thus this method was used in this study with the objective to investigate the amount of mandibular ridge height in relation of aging and length of edentulism. Materials and Methods: The study was limited to men to overcome variables associated with osteoporosis and menopause in women. 60 complete denture wearers' male patients were selected from the department of Prosthodontics, K.L.E.S's institute of dental sciences, Belgaum. The groups were divided into two resorptive age groups those between 40 to 60 years of age and those over 60 years of age. Each patient was informed about the study and after obtaining informed consent an OPG was made. Then the measurement was made on OPG using Wical and Scoope method to determine the ridge height in relation to age and edentulism period. Results: To test measurement significance one way analysis of variance (ANOVA) was applied between the resorptive age groups and within resorptive age groups. A significant P=0.00086 value was obtained in younger resorptive age group but it was non significant P=0.1223 was obtained in older resorptive age group. A student unpaired t-test was used to measure the significance between the resorptive age groups for the same edentulism period. Conclusion; Within the limitations of this study it was concluded that the mandibular ridge height reduction was linear throughout the ages.

“…The masticatory pressure applied to the denture is transmitted to the mucosa by the denture base. Well‐distributed pressure might deliver mechanical stimulation necessary for maintenance of integrity of the tissue and prevent disuse atrophy of the edenturous alveolar process (Schlosser, 1950; Weinmann & Sicher, 1955; Nedelman et al ., 1970). Excessive concentration of pressure, however, exerts adverse effects resulting in pathology of mucosal and osseous tissues (Nedelman et al ., 1970; Razek & Shaaban, 1978; Watson & MacDonald, 1982).…”

This study examined the effect of masticatory pressure transmitted directly to the hard palate mucosa on the final stage of terminal differentiation of keratinizing system of rats with and without streptozotocin-induced diabetes mellitus. In the nondiabetic rats with masticatory pressure, the number of terminal-deoxynucleotidyl-transferase-mediated deoxyuridine-triphospate-biotin nick end labelling (TUNEL) positive cells tended to increase about twice as much as in the nondiabetic rats without pressure with and without denture. A similar tendency of increase was observed in the diabetic rats without pressure. The synergy of the mechanical pressure and diabetic condition for 2 weeks greatly accelerated the DNA fragmentation, showing 8-fold increase in TUNEL positive cells over the normal control, and caused exfoliation of the stratum corneum. A 4-week exposure of diabetics to the masticatory pressure induced laminar splitting in the midst of the spinosum. Some cells in the stratum granulosum exhibited a sign of DNA fragmentation when laminar splitting took place in the vital cell layer. Premature DNA fragmentation may disturb the adhesion between spinosum cells and prevent the maturation of stratum corneum. Increase in Bax protein-like immunoreactivity in these epithelial cells as revealed by immunocytochemistry may underlie the premature DNA fragmentation in the oral masticatory epithelium under pressure in diabetic patients.

“…Osteoclastic activity has different rates in two arches with higher resorption in the mandible compared to the maxilla [ 11 , 12 ]. Osteoblastic activity and ridge resorption are governed by various systemic and local factors leading to alteration in the structure of the arches [ 13 – 16 ]. The osteoclastic activity plays a key role in denture support loss leading to unstable and ill-fitting dentures demanding frequent relining of the denture with bone resorption.…”

Owing to the early tooth loss in a large population, the need for removable prosthodontic therapy has widely increased. Loss of teeth can occur due to trauma, periodontal disease, dental caries, and/or oral health negligence. The removable prosthesis is preferred over other teeth replacement methods owing to its cost-effectiveness. However, due to continuous alveolar bone resorption, relining of the removable prosthesis is needed regularly. We aimed to assess the prevalence of vitamin D deficiency and bone turnover marker concerning bone mineral density. Eighty complete denture wearers either in the maxilla or in the mandible or both constituted the study sample. Before the study, all subjects were explained the procedures of the study, and informed consent was obtained before proceeding with the study. Subjects were instructed to provide an early morning sample in a fasting state as serum osteocalcin (OCN) and C-terminal telopeptide (C-Tx) have diurnal variations. Blood samples were collected, and samples were ruled out for 25-OH vitamin D, serum OCN, and C-TX. To determine the association between frequency of relining and bone turnover marker, the collected data were subjected to statistical evaluation. Significant correlations were seen between bone C-Tx, turnover markers (p<0.001), and frequency of denture relining and osteocalcin (p<0.001). No statistically significant effect of gender, vitamin D levels, age, calcium levels, vitamin D supplements, and diabetes was seen on denture relining frequency. The present study concludes that an elevated level of the bone turnover markers such as OCN and C-Tx increases the frequency of relining.
