The Effect of Denture Adhesives on Denture Quality and Occlusal Force.

Complete dentures (CDs) have been associated with substantial problems regarding edentulous patient's function. Denture adhesives seem to be useful adjuncts to improving retention and stability. A clinical study was undertaken to investigate the effect of a denture adhesive (DA) on function in complete denture wearers along with the quality of their CDs. Thirty complete denture wearers participated in the study. The first phase of the experimental procedure comprised 3 groups of measurements performed at 3 distinct time points: the initial measurement (T1), a 2nd measurement after 15 days of DA daily application (T2), and a 3rd measurement following a 15-day washout period (T3). The second phase consisted of the follow-up measurements. The measurements included: recording of relative occlusal force (ROF), distribution of occlusal contacts (DOC) and center of force (COF) using the T-Scan 9.1 device and functional assessment of dentures using the FAD index. The DA use induced a statistically significant increase in ROF (p-value=0.003) and decrease in COF (p-value⟨0.001) and DOC (p-value=0.001). The overall FAD score significantly improved (p-value⟨0.001). The use of the DA improved the occlusal force, the distribution of occlusal contacts as well as the qualitative characteristics of CDs.

Evaluation of the Denture Impact on the Palatal Rugae: An Original Research.

The palatal rugae may alter their shape based on the various physical pressures that they had to endure. This study's objective is to assess the various alterations in the palatal rugae parameters among the complete denture wearers. Forty subjects in all were chosen for the study. The control group interventional groups had an equal number of participants who were further equally distributed based on gender. For all of the participants, mucostatic maxillary alginate imprints were taken, and gypsum castings were created. They were called at the scheduled intervals of 2, 6, and 12 months following the treatment. The models used during those recalls and all of the palatal rugae were examined under a microscope for quantity, length, form, orientation, and unifications. The unpaired t-test was used to statistically examine palatal rugae alterations. Following the wear of the dentures, the experimental group's primary, secondary, and fragmented rugae all gradually shrank in length. In terms of statistics, the alteration solely affected primary rugae and was significant (P < 0.001). After a year of wearing dentures, a minimal change in rugae's form was noticed in the denture groups, but it was statistically not substantial (P > 0.05). Due to the prolonged mechanical stress the dentures placed on the palatal rugae, complete denture users saw a significant reduction in the length of their primary rugae. Rugae number, orientation, and unification were among the other criteria that did not change during the course of the study. Analysis of the palatal rugae may not be useful in identifying people wearing full dentures. However, in forensic investigations, rugae may act as an adjunct to other methods like fingerprints and DNA analysis.

Assessment of Denture Cleanliness among Complete Denture Wearer in Chitwan

Introduction: Oral cleanliness is important for all to maintain the overall health status. It is also important for the old aged edentulous people with dentures. The complete dentures are custom made device which are the replacement for the missing all tooth of mouth. Many microorganisms adhere to the surfaces of dentures and form denture plaque and calculus. They are there due to inadequate denture hygiene maintenance. This study was performed with the aim of assessing cleanliness of complete dentures among the denture wearers.Methods :A descriptive cross-sectional study conducted among 140 complete denture in the Department of Prosthodontics and Maxillofacial Prosthetics at Chitwan Medical College and Hospital. A convenience sampling method was used in this study. After taking the sociodemographic information and other information related to dentures, the participants dentures were evaluated with disclosing agent. The stained dentures were then assessed according to the Denture Cleanliness Index. Data was analyzed by using descriptive statistical tools in SPSS-16 and results were presented in form of tables.Results: The mean age of 140 patients was 71.39±5.80 years. There were 81 (57.9%) females and 59 (42.1) males. About 27 (19.3%) denture wearers did not remove dentures from their mouth at night. Among total, 81 (57.9%) of participants brushed their dentures with water. Denture Cleanliness Index scores of 2 was observed in 64 (45.8%) of denture wearers. Conclusions: It can be concluded that majority of participants had uncleaned dentures suggesting the need ofproper denture hygiene instructions and routinely follow-up for the cleanliness of dentures and their overall intraoral health status whether or not there were denture stomatitis.

Clinical Efficacy of Two Denture Adhesives Among Complete Denture Patients: A Cross-over Randomized Clinical Trial

Aims and objectives: The clinical efficacy of different forms of denture adhesives have been inconsistent among studies with unclear differences among them. The aim of this study is to evaluate the masticatory efficiency and satisfaction of complete denture wearers without and with the use of two different forms of commercially available denture adhesives.&#x0D; Material and Methods: 30 edentulous participants with new complete dentures placed one month before the commencement of the study were included in this cross-over randomized clinical trial (CTRI/2021/07/035238) which compared a powder adhesive and a cream adhesive along with no adhesive use. The objective assessment used the Edlund and Lamm index for masticatory efficiency and the subjective assessment followed a specially designed questionnaire. Both assessments were carried out on days 0,7 and 21. One-way ANOVA was used to compare the objective data and the questionnaire responses were obtained as percentages.&#x0D; Results: The one-way ANOVA test for difference between the groups was statistically insignificant for all layers (P&gt;.05). The questionnaire responses revealed that 53.3% of the participants preferred the use of cream adhesive over powder adhesive.&#x0D; Conclusions: No significant difference in the masticatory efficiency was noted between the two denture adhesives and without adhesive use. Patient satisfaction was greater with adhesive use showing a predilection towards cream adhesive due to its longer duration of action and improved chewing ability.

The impact of residual ridge morphology on the masticatory performance of complete denture wearers

Statement of the problemMorphology of the residual ridge (RR) is expected to influence the masticatory performance (MP) of complete denture (CD) patients, but considerable details of this relationship are unknown. PurposeWe aimed to investigate the association between the objective MP and RR morphology of CD wearers and other contributory factors affecting their MP. Materials and methodsSixty-five patients with well-fitting upper and lower CDs with no complaints of pain were enrolled. The objective MP was measured using test gummy jelly and a fully automated measuring device. The RR form was divided into U-type, V-type, I-intermediate, and F-Flat, then combinations of upper and lower RR forms (combined RR) were classified. The height was measured using CD's denture basal surface replicas, while occlusal contact of CDs was assessed using a tooth contact analysis system. The relationship between surveyed factors and MP was evaluated using Spearman's rank correlation, Kruskal-Wallis test, generalized linear regression, and analysis of covariance. ResultsParticipants with F–F and V–F combined RR forms had the lowest MP, while those with U–U and U–I forms had the highest MP, regardless of RR height. Participants with low RR height had the lowest MP, and those with high RR height had the highest MP, regardless of RR form. The analysis of covariance revealed that mandibular RR height, combined RR forms, and total occlusal contact area significantly affected the MP. ConclusionsOur findings confirmed that the mandibular RR height, RR form combinations, and occlusal contact influence the MP of CD wearers.ClinicalImplications:The MP of CD wearers varied, depending on the height and form of the RR, as well as the occlusal contact area of the CDs. The results of this manuscript show that the morphology of the denture bearing area and the occlusion of the CDs are essential factors in predicting the treatment outcome of CD wearers. This allows the clinician to fabricate a complete denture with the denture basal surfaces adjusted and occlusion provided according to the patient. CD patients can be educated on how to chew to improve MP based on their own RR morphology.

Relationship between Occlusal Vertical Dimension and Tongue Pressure in Complete Denture Wearers

Data on estimating the vertical dimension of occlusion（VDO）for fabricating a complete denture based on tongue pressure, which is related to masticatory and swallowing functions, are scarce. This study aimed to examine the changes in tongue pressure on raising or lowering of the VDO from the most comfortable position（MCP）. Ten edentulous, including Eichner C3, patients with existing dentures（six men and four women; mean age, 78.6±7.14 years）were recruited from a hospital setting. Twelve different height-positioning stimulus stainless-steel blocks were used（from +1 mm to 6 mm and +9 mm and from -1 mm to -4 mm）. VDO from the most comfortable position （MCP）and the tongue pressure at the respective height were measured. One-way analysis of variance（ANOVA）and Dunnett’s test were performed to analyze the differences in tongue pressure at different VDOs. There were no significant differences between the stimulus intervals（-1 to -4 mm, p = 0.99）on lowering VDO from MCP. Tongue pressure decreased marginally when the VDO was raised +5 mm from the MCP（p=0.054）; it continued to show a significant decrease at +6 mm（p=0.041）and +7 mm（p=0.035）from MCP. Tongue pressure did not change significantly when VDO was lowered and raised to +5 mm from MCP. These results suggest that VDO may be set to 5 mm from MCP when fabricating new complete dentures.

Relation between the Changes in the Vertical Dimension of Occlusion and Patient’s Subjective Evaluation in Complete Denture Wearers

The vertical dimension of occlusion（VDO）must be correctly estimated when fabricating complete dentures to achieve efficient mastication and swallowing. The comfortable zone（CZ）method for VDO estimation is based on trichotomous subjective response. However, the difference in comfort level within and out of the CZ still needs to be determined. Therefore, this study aimed to examine the differences in subjective comfort on a 100-mm visual analog scale（VAS）when raising or lowering the VDO and to assess the relationship among the responses to the CZ method. Eight edentulous patients（five men and three women, with a mean age of 78.5±7.6 years）were recruited. The VAS score was obtained two times at the most comfortable position（MCP）and when it was raised from +1 to +7 mm（7VDO）. The VAS score was also obtained when the MCP was lowered from -1 to -3 mm（3VDO）. One-way analysis of variance and Bonferroni’s multiple comparison test were performed to analyze the differences in VAS scores at 11 VDOs. The VAS score significantly decreased when the VDO was raised by +3 mm from the MCP（p = 0.009）and continued to decrease in +4（p = 0.001）, +5, +6, and +7 mm（p < 0.001, respectively）. In addition, it significantly decreased when the VDO was lowered by -2 mm from the MCP（p = 0.048）. The results suggest that VDO estimates may be appropriate between -1 and +2 mm from the MCP when fabricating new complete dentures.

Comparison of Oral Health-Related Quality of Life in Partial and Complete Denture Wearers: A Propensity Score Analysis.

Dentures, both partial and complete, have been shown to have the same impact on one's quality of life. Due to the impossibility of randomization in these studies, they are prone to selection bias. This study aimed to compare the effect of partial and complete dentures on oral health-related quality of life (OHRQoL) by propensity score to overcome selection bias. This is a cross-sectional descriptive-analytic study. A total of 1376 people participated in this study. Age, sex, marital status, education level, smoking, smoking opium and its derivatives, and dental visit was collected by a checklist. OHRQoL was measured by the OHIP-14 questionnaire. The generalized boosted model was used to estimate the propensity score. Missing data were imputed using multiple imputations with mixed models. The assumptions of multivariable regression analysis and propensity score method were first examined, and then the quality of life related to oral health was compared between the two groups. The regression model's assumptions were not verified due to high skewness and collinearity. The results of the normality test (P < 0.001) and goodness fit test (P < 0.001) revealed that the regression model did not fit the data. The propensity score method reduced at least 76% of the bias resulting from the distribution difference between the confounding variables and was used for analysis. In the regression and propensity score method, the results showed that the total OHIP-14 score of the complete prosthesis group was higher than the partial prosthesis group at 3.92 (95% CI = (2.18,5.65)) and 3.64 (95% CI = (1.93,4.53)), respectively. This difference was clinically and statistically significant (P < 0.001). In addition, there is a significant difference in the two groups based on propensity in all seven areas (P < 0.001). But there is no significant difference in the regression adjustment of the Functional limitation of the two groups (P = 0.035). The propensity score has fewer assumptions than the regression method and may be more reliable for OHIP scores. The propensity score analysis revealed that despite the costs and repair issues associated with partial dentures, complete denture wearers have lower OHRQoL than partial denture wearers.

PREVALENCE OF SIGNS OF TEMPOROMANDIBULAR DISORDERS IN HEALTHY ASYMPTOMATIC COMPLETELY EDENTULOUS INDIVIDUALS AND THE EFFECT OF DENTURE ON TEMPOROMANDIBULAR DISORDERS

Background and objectives: Temporomandibular disorders (TMD) are a multi-factorial issue characterized by signs and symptoms that eventually restrict or may impede an edentulous patient’s physiological activity. The current study aimed to ascertain the prevalence of TMD among edentulous individuals, and their association with risk factors such as gender, age, educational level, habitual Khat chewing, economical status, duration of edentulousness, the age, and vertical dimension of occlusion (OVD) of the present dentures. Materials and Methods: This study involved a thorough evaluation of 400 edentulous Yemeni patients who were undergoing prosthetic treatment at the Faculty of Dentistry Sana'a University and the University of Sciences and Technology, 114 with denture and 286 without denture. This evaluation of TMD signs and symptoms was performed using the Helkimo index. The outcomes were analyzed by correlating the research variables and the prevalence of signs and symptoms of TMD using chi-squared tests. Results: The study’s findings showed that signs and symptoms of TMD were 82.5% and 55.3% among complete denture wearers and 80.4% and 49.0% among non-denture wearers, respectively. Furthermore, the most frequent sign and symptom was the joint sounds. This study revealed a statistically significant association between the prevalence of TMD symptoms and patient gender and between TMD signs and symptoms and OVD in denture wearers. Conclusion: The current study supports the need to evaluate the potential impact of TMD on completely edentulous individuals and to take caution while receiving dental therapy and prosthetic rehabilitation.

Impact of Acrylic and Silicone-Based Soft-Liner Materials on Biting Force and Quality of Life of the Complete Denture Wearers: A Randomized Clinical Trial.

This rerandomized clinical trial evaluated the influence of soft liners (SL) on biting force, pain perception, and the oral health-related quality of life (OHRQoL) of complete denture wearers. Twenty-eight completely edentulous patients complaining of ill-fitting lower complete dentures were selected to participate in the study from the Dental Hospital, College of Dentistry, Taibah University. All patients received new complete maxillary and mandibular dentures; then they were randomly divided into two groups (14 patients in each group): the acrylic-based SL group, in which the mandibular denture was lined with an acrylic-based soft liner, and the silicone-based SL group, in which the mandibular denture was lined with a silicone-based soft liner. OHRQoL and maximum bite force (MBF) were assessed in this study before denture relining (baseline), then at one month and three months after relining. The finding showed that both treatment modalities significantly improved the OHRQoL of included patients at one-month and three-month periods compared to baseline records (i.e., dentures before relining) with a statistically significant difference (p < 0.05). However, there is no statistical difference between groups at the baseline, one-, and three-month follow-up periods. Regarding maximum biting force, when acrylic-based SL is compared to silicone-based SL, there is no statistical difference between groups at baseline (75 ± 31 and 83 ± 32 N) and one-month follow-up periods (145 ± 53 and 156 ± 49 N); however, after three months of function, the silicone-based group recorded 166 ± 57 N statistically significant high biting force compared to the acrylic-based group that recorded 116 ± 47 N (p < 0.05). Permanent soft denture liners positively affect maximum biting force, pain perception, and OHRQoL more than conventional dentures. After three months, silicone-based SL outperformed acrylic-based soft liners in maximum biting force, which may indicate better long-term results.

Impact of Complete Denture and Mandibular Advancement Device in the Management of Completely Edentulous Obstructive Sleep Apneic Individuals: A Systematic Review with Meta-Analysis.

Obstructive sleep apnea (OSA) is an underdiagnosed and potentially serious disorder that is accentuated by edentulism. The overclosure of the mandible and a potential upper airway collapse during sleep creates challenges in treating edentulous sleep apneic patients. To evaluate complete dentures and mandibular advancement devices as potential oral appliances in the management of sleep apnea in completely edentulous patients. The study design was a systematic review with meta-analysis. The search criteria complied with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and the keywords in population, intervention, control, and outcomes (PICO) format was systematically searched for relevant research articles published till August 2021 in an electronic database (PubMed, Cochrane, Science Direct, Ovid). Randomized controlled trials and cohort studies were included that compared the effectiveness of oral appliances on apnea-hypopnea index (AHI), airway space, and quality of sleep in edentulous sleep apneic patients. 1785 articles were derived from the initial search and based on inclusion criteria, 10 articles were systematically filtered for qualitative analysis and assessed for risk of bias using the Cochrane risk of bias tool and ROBINS-I tool. Out of the 10 articles, 5 articles were taken for quantitative analysis. The use of a mandibular advancement device (MAD) showed a decrease in AHI score, but the available data was heterogeneous to conduct a meta-analysis. The mean difference of AHI for the random effect model between the non-complete denture and complete denture wearers at sleep was -0.49[95% CI (-1.47,0.48)] events per hour, but the change was non-significant (p>.05). The complete dentures as an oral appliance had reduced apneic episodes in completely edentulous sleep apneic patients, but the effectiveness cannot be solely attributed to the prosthesis in the treatment of OSA. MAD showed greater improvement in reducing AHI, however, the level of evidence was inadequate to provide a conclusive statement.

ANTI-CANDIDAL EFFICACY OF OREGANO IN DENTAL PROSTHETICS

Introduction: Denture hygiene is considered as an essential part of oral hygiene maintenance for the well-being of oral soft tissue in denture wearers. Denture induced stomatitis is common among denture wearers and that can be due to adherence of candida species.The purpose of the present study is to determine and compare the anti-candidal effect of Oregano against Candida albicans for using it efciently as a denture cleansing agent. Swab from the tissue surface of 20 complete acrylic denture wearers w Materials And Methods: ere collected and cultured to isolate the Candida albicans. The plant materials were soaked in 99.9 % ethanol and pure extracts were made by the cold maceration method. Various concentrations of Oregano (1 %, 2 %, 4 %, 8 % and 16 %) dilutions were done. Fluconazole was taken as a control to compare with the plant products. The Disc diffusion method was done to nd the zone of inhibition by pre-treating the discs with herbal extracts. The zone of inhibition was measured in millimetres. The mean value of zone of inhibition of Oregano w Results: as less when compared to the uconazole of higher concentrations. The differences between two groups were analyzed using one way ANOVA test. Oregano showed least anti-candidal Conclusion: effect when compared to uconazole, Where it can have effects on other species of candida

Willingness to accept or refuse mandibular implant overdenture treatment: A prospective study on edentulous enrolled in a clinical trial.

Several complete denture wearers have major complaints and may be benefitted from implant treatment. However, the factors that shape the demand for and utilization of implants need further investigation. The aim was to evaluate edentulous patient's willingness to accept or refuse the offer and provision of implant-retained treatment. As part of a clinical trial, edentulous subjects were offered a mandibular overdenture retained by four mini-implants opposing a conventional maxillary denture. Treatment was offered without any financial costs for the patients. Patients' level of interest in receiving treatment was assessed using a 5-point Likert scale, and they were asked to respond to a list of reasons that led to their decision to accept or refuse implants. Those who refused implants received conventional prosthodontic interventions as required, and those who accepted implant treatment underwent surgical planning and implant placement. Of 175 eligible subjects, 147 accepted the offer of treatment and were invited to take part in the study (69.4% women, mean age 67.4± 10.0 years). Overall, 111 patients (75.5%) expressed a positive intention to undergo implant treatment at the initial contact. Implant treatment was performed for 56.3% (9/16) of those who answered 'probably yes' about their level of interest in implant treatment on the Likert scale, and 69.6% (64/92) of 'certainly yes' (p< .001). Older subjects were less likely to receive implants (OR=0.93; p= .036), whilst those with a positive intention towards implants (OR=3.15; p= .001), those previously treated by the dental team (OR=7.89; p< .001), and who actively demanded implants (OR=18.1; p< .001) were more likely to accept treatment. Improved chewing was the most common reason for accepting implants, whilst fear of surgery was the most reported reason for refusal. Refusal of implants was high among edentate patients even when financial costs were removed. Patients' initial attitude towards acceptance is a key factor in the demand for and uptake of implant therapy.

Masticatory muscle activity in complete denture wearers: a surface electromyographic analysis

The investigation of the adaptation process to a new denture is relevant to understand the control of muscles. Surface electromyography provide reproducible data of masticatory muscle function and helps to assess the performance of dentures. This longitudinal study simultaneously evaluated electric potential in masseter and anterior temporalis during clenching at maximum intercuspation position and mastication at 2 months after denture insertion and one year later was done in complete denture patients. The surface electrodes were placed in anterior temporalis and ma-sseter region of 22 patients during maximum voluntary clenching and chewing. Statistical analysis was performed by paired t-test. A significant increase in electrical activity was found during clenching and chewing after one year compared to two months. The overall mean EMG value of masseter was significantly higher during chewing at 2 months (p&lt;0.001) and 1 year (p&lt;0.001). A negative correlation was found with respect to age and EMG value of ma-sseter. It is concluded that the electrical activity presented statistically significant difference after one year indicating improved functional quality. A good rehabilitation improves the efficiency of muscles. Monitoring the effect of rehabili-tation on stomatognathic system help to preventively warn about dysfunctions and treatment modifications needed.

Clinical Trial to Assess Physiology and Activity of Masticatory Muscles of Complete Denture Wearer Following Vitamin D Intervention.

Background and Objectives: Little information is available on the role of Vitamin D as a micro-nutrient deficiency with masticatory muscle efficiency and its effect on the function of removable prosthesis. The aim of this study was to evaluate the role of vitamin D on masticatory muscle activity among completely edentulous patients and its effect on the retention of removable complete dentures (RCDs). Materials and Methods: A non-randomized clinical control trial was conducted on completely edentulous patients (60.53 ± 7.01 years) in the Indian population between 2017 and 2019. Subjects were evaluated for temporomandibular disorders according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Serum Vitamin D (S Vit D) levels, Ultrasonography (USG), and surface Electromyography (sEMG) readings of the masseter muscle were recorded at enrolment (Level 0), after 3 months of Vitamin D therapy (Level 3), and after consecutive 3 months of maintenance therapy, i.e., after 6 months from baseline (Level 6). The fabrication of new RCDs was done for all after the enrolment, and the retention of RCDs was assessed by asking a question regarding denture retention and asking respondents to mark their satisfaction on a 5-point Likert scale. Data were analysed using ANOVA, Paired'-test and Pearson correlation coefficients. A p-value less than 0.05 indicated a statistically significant association. Results: Between enrolment and a six-month follow-up, S Vit D levels showed an increase from 16.03 ± 5.68 ng/mL to 31.35 ± 9.28 ng/mL, showing an increase of 15.32 ± 9.38 ng/mL (95.57% rise). Statistically significant values were observed for USG and sEMG. Conclusions: Results showed that S Vit D affects masticatory muscle activity by improving its thickness and boosting its tonicity. Healthy muscles assist in the retention of RCDs, consequently aiding in mastication, speech, and phonetics, hence improving patient satisfaction. Clinical implication: Acknowledging the fact that the prevalence of Vitamin D deficiency is worldwide. We suggest Vitamin D therapy as a nutritional intervention among the elderly completely edentulous population, following dietary counselling, and consider Vitamin D therapy to be an adjunct to nutritional counselling for improving masticatory muscle activity and efficiency, which aids in RCD retention and stability. Consequently, improving oral health-related quality of life for individuals.

Influence of Adhesive Use on Swallowing in Removable Complete Denture Wearers

Background: The objective of conventional complete dentures is to reestablish the functions of the stomatognathic system in edentulous individuals. Adhesives are used for denture retention to help the masticatory function. The objective of this investigation was to evaluate the effect of denture adhesive on the swallowing of complete denture wears. Methods: Nine upper and lower complete denture wearers and 14 individuals with teeth were assessed with videofluoroscopy at 30 frames by second and analyzed frame by frame. The denture wears subjects were assessed without dentures, with dentures without adhesive, and with dentures and adhesive. Duplicate assessments were made with swallows of 10-mL thin-liquid bolus, 10-mL extremely-thick bolus, 5-g cookies, and 2-g toasts. Results: Laryngeal vestibule closure, pharyngeal transit, upper esophageal sphincter opening, and oropharyngeal transit took longer in denture wearers than in controls. Laryngeal vestibule closure time and upper esophageal sphincter opening when swallowing thin liquid were shorter with dentures and adhesive than without adhesive. With extremely thick bolus, the pharyngeal transit time and upper esophageal sphincter opening were shorter with adhesive use. Residues in the oral cavity occurred more frequently in the denture wearers than in the controls, for all boluses. Removable complete denture wearers have longer pharyngeal transit of thin liquid and extremely thick boluses, which decreases with adhesive use. Conclusion: Adhesive use cause a favorable effect on pharyngeal swallowing of thin and thick boluses in complete denture wearers.

A Randomised Clinical Study of the Effect of a Denture Soft Liner on Mandibular Ridge Resorption in Complete Denture Wearers After One and Two Years Of Denture Insertion

Abstract: Aim: The aim of this study was to assess the effect of soft denture liners on mandibular ridge resorption in complete denture wearers after two years of use. Methodology: The study included 32 patients ranging in age from 35 to 65 years old. Those patients were completely edentulous with well formed ridges, Class I relation and no medical problem. Thirty two selected patients were divided into two groups, namely Experimental group and Control group. Control group (n = 16, 8 males and 8 females) received conventional maxillary and mandibular complete dentures. Whereas in Experimental group, (n = 16, 8 males and 8 females) silicone lined lower complete denture were made. Three panoramic radiographs (orthopantomogram [OPG]) were taken for each participant to assess the amount of bone resorption; immediately, one year, and two years after denture insertion. For comparing two groups at three different time intervals, analysis of variance (ANOVA) two way with post-hoc tests was used. A statistically significant pvalue of less than 0.05 was considered. Results: After denture delivery, there was significant change in bone height in all patients ( p &lt; 0.001) . The comparison of bone height between the two groups in different regions at different time intervals revealed a significant difference in bone levels at baseline to one year and baseline to two years. However, Experimental group experienced 50% less bone loss than control group over a two-year period. Conclusion: Based on the findings of the current study, it can be inferred that use of soft liners helps in reducing residual ridge resorption significantly when compared with conventional denture material.
