Self-reported oral health in the Dutch 100-plus Study of cognitively healthy centenarians: an observational cohort study.

BACKGROUND: Due to improved healthcare, more people reach extreme ages. Oral health in the oldest-old has thus far been poorly described. Here, we investigated self-reported oral health factors, use of professional oral health care, and associations with clinical measures in centenarians considered cognitively healthy. METHODS: In this observational cohort study, we included 162 (74% female) centenarians from the Dutch 100-plus Study cohort who self-reported to be cognitively healthy, as confirmed by a proxy. Centenarians were questioned about their physical well-being including medication use and their cognitive functioning was evaluated using the Mini-Mental State Examination. Questions regarding oral health included preservation of teeth, oral pain or discomfort, chewing ability, xerostomia, and time since last visit to an oral health care provider. Associations between oral health and clinical measures were investigated with ordinal logistic or linear regression analyses, adjusted for gender, age, and education. RESULTS: The majority of the centenarians indicated to have good oral health: 76% felt no oral pain/discomfort, 65% indicated to chew well; while only 18% had symptoms of xerostomia. Of all centenarians, 83% were edentulous and were wearing removable complete maxillary and mandibular dental prostheses, 1% was edentulous with no dental prosthesis, while 16% was dentate with or without removable partial dental prostheses (10 and 6% respectively). Dentate and edentulous centenarians experienced similar levels of oral pain and/or discomfort, chewing ability, xerostomia, and their cognitive functioning was similar. No relationship between cognitive functioning and chewing ability was found. Xerostomia was associated with medication use (p = .001), which mostly regarded medications for cardiovascular diseases, diuretics, anti-coagulants, and antacids. Only 18% of the centenarians visited an oral health care provider during the year prior to the interview, of whom 48% were dentate centenarians. Notably, 49% of the centenarians had not visited an oral health care provider for ≥10 years. CONCLUSIONS: Most centenarians were edentulous and did not report oral complaints. Less than one-fifth of the centenarians continued to seek regular professional oral health care. Since the proportion of dentates in the oldest-old will increase in the near future, a proactive attitude toward this group is necessary.

Associations of number of teeth with medical costs and hospitalization duration in an older Japanese population.

AIM: Many studies have reported close relationships between oral and systemic health. We explored the association of the number of remaining teeth with medical costs and hospitalization duration in people aged 75 and 80 years. METHODS: Oral health examinations were carried out at dental clinics in 2014. Medical cost and hospitalization duration data for fiscal year 2015 were obtained from the Mie Prefecture health insurer. We analyzed the data of 4700 individuals who met our inclusion criteria: 2745 75-year-olds and 1955 80-year-olds. The effects of remaining tooth numbers on medical costs and hospitalization days were analyzed using a generalized linear model with log link adjustment for confounders. RESULTS: Total medical costs for all diseases were significantly higher in those with 20-27, 10-19 and 1-9 teeth, and in edentulous older individuals, compared with those with 28 teeth. Outpatient medical costs for diabetes were significantly higher in those with 20-27 and 1-9 teeth. Inpatient medical costs for digestive cancers were significantly higher in those with 10-19 and 1-9 teeth, and in edentulous older individuals. Hospitalization for digestive cancer was significantly longer in those with 20-27, 10-19 and 1-9 teeth, and in edentulous older individuals, than in those with 28 teeth. The number of teeth as a continuous variable was significantly inversely associated with medical costs for cerebrovascular disease and digestive cancer, and hospitalization days for digestive cancer. CONCLUSION: Small numbers of teeth were associated with higher medical costs and longer hospital stays for older Japanese. Geriatr Gerontol Int 2019; 19: 335-341.

RELATIONSHIP BETWEEN GENERAL HEALTH, ORAL HEALTH AND HEALTHY LIFESTYLE IN ELDERLY POPULATION (REVIEW).

This literature review aims to investigate how a poor oral health impacts on general health and healthy lifestyle of elderly people. The literature review was performed using ScienceDirect, Scopus and PubMed databases to identify relevant published studies. The year of publication was limited to over the past 5 years and the language was limited to English. Having considered the relevant articles' abstracts the 36 articles were selected. Systematical literature revision shows that recently, the older population has increased worldwide and it is being predicted to keep growing in near future. As age-related changes are observed in oral cavity, geriatric dentistry becomes more relevant to investigate oral disorders and to take relevant measures in elderly population. There is an urgent need to clarify the correlations between oral and general health. Unsatisfactory oral conditions lead to serious systemic diseases. Based on the currently available evidence, better collaboration between medical and dental fields is required in order to create and maintain healthy elderly population. A special association with professional group is important for implementation of new programs, in order to enhance and maintain satisfactory oral hygiene, oral health and oral health related quality of life.

The influence of immediately loaded implant treatment in the atrophic edentulous maxilla on oral health related quality of life of edentulous patients: 3-year results of a prospective study.

BACKGROUND: To evaluate oral health related quality of life (OHQoL) in edentulous patients treated with immediately loaded implants in the maxilla. METHODS: Fifty-one edentulous patients in two centers received six maxillary implants each were loaded within 24 h with provisional restoration. Definitive restoration was delivered 20-24 weeks later. OHQoL was evaluated preoperatively with the Oral Health Impact Profile 49 questionnaire (OHIP-49) and on five subsequent occasions. OHIP-49 includes seven domains representing functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. A reduction in OHIP scores indicated an improved OHQoL. RESULTS: Forty-five patients reached the three-year follow up. OHQoL improved after treatment. A plateau of OHQoL improvement was observed at 12 months after surgery. The seven domains improved at different pace, 12 weeks to 12 months after treatment. OHIP showed continuously low scores with no significant changes at consecutive visits 12 months to three years after treatment. Dental status with removable prosthesis in the mandible had a negative impact on OHQoL prior to and during treatment, but did not affect OHQoL after permanent restoration was placed. Patients age or gender did not affect OHQoL. CONCLUSIONS: Patients with edentulous maxilla who received prosthetic rehabilitation on immediately loaded implants experienced the highest improved OHQoL 12 months after implant installation. Quality of life related to oral health continued to be high after three years. Edentulous patients with atrophy of the maxilla experience an improved OHQoL after implant treatment with immediate loading protocol. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT00711022 .

Design and fabrication of complete dentures using CAD/CAM technology.

The aim of the study was to test the feasibility of using commercially available computer-aided design and computer-aided manufacturing (CAD/CAM) technology including 3Shape Dental System 2013 trial version, WIELAND V2.0.049 and WIELAND ZENOTEC T1 milling machine to design and fabricate complete dentures.The modeling process of full denture available in the trial version of 3Shape Dental System 2013 was used to design virtual complete dentures on the basis of 3-dimensional (3D) digital edentulous models generated from the physical models. The virtual complete dentures designed were exported to CAM software of WIELAND V2.0.049. A WIELAND ZENOTEC T1 milling machine controlled by the CAM software was used to fabricate physical dentitions and baseplates by milling acrylic resin composite plates. The physical dentitions were bonded to the corresponding baseplates to form the maxillary and mandibular complete dentures.Virtual complete dentures were successfully designed using the software through several steps including generation of 3D digital edentulous models, model analysis, arrangement of artificial teeth, trimming relief area, and occlusal adjustment. Physical dentitions and baseplates were successfully fabricated according to the designed virtual complete dentures using milling machine controlled by a CAM software. Bonding physical dentitions to the corresponding baseplates generated the final physical complete dentures.Our study demonstrated that complete dentures could be successfully designed and fabricated by using CAD/CAM.

The Influence of Age in the Relationship between Cerebral Small Vessel Disease and Edentulism. The Atahualpa Project.

BACKGROUND: The association between edentulism and cerebral small vessel disease is controversial. We aimed to assess this relationship in community-dwelling older adults living in rural Ecuador. METHODS: MRI was performed in 311 (81%) of 385 individuals ≥60 years enrolled in the Atahualpa Project. Participants were classified in 2 groups according to whether they have severe edentulism (<10 remaining teeth) or not. Using multivariate logistic regression and exposure effect models, we assessed whether edentulism correlated with severity of white matter hyperintensities (WMHs), after adjusting for relevant confounders. RESULTS: Mean age of participants was 70 ± 8 years (57% women). Severe edentulism was noticed in 152 (49%) individuals and moderate-to-severe WMHs in 81 (26%). In univariate analyses, moderate-to-severe WMHs were more common among edentulous individuals (OR 1.88, 95% CI 1.13-3.16, p = 0.015). Such difference became non-significant in the logistic regression model (OR 1.65, 95% CI 0.91-2.99, p = 0.098); in this model, the single relevant covariate was age. A weighted exposure effect model revealed no association of severe edentulism with moderate-to-severe WMH (average exposure effect: 0.73, 95% CI -0.01 to 0.16, p = 0.10). CONCLUSION: The relationship between edentulism and diffuse subcortical damage of vascular might be explained by the high prevalence of both variables in older adults.

Changes in biting forces with implant-supported overdenture in the lower jaw: A comparison between conventional and mini implants in a pilot study.

The biting ability of patients improves noticeably after receiving implant-supported overdentures in comparison to conventional complete dentures. However, the change of biting with such treatment concepts has been quantitatively investigated in only a limited number of studies. The aim of the present study has been to measure the biting forces of edentulous patients with complete dentures and after receiving implant-supported overdentures. A total of 26 edentulous patients were included. Ten patients received two to four conventional implants (control group, Ø3.3-3.7mm, L11-13mm) and 16 patients received four to five mini implants (study group, Ø1.8-2.4mm, L13-15mm) inserted in the mandibular interforaminal region. All patients received a lower overdenture with ball/rubber ring attachments and a complete denture for the maxilla. The biting forces were measured using Prescale pressure sheets type low before the insertion of implants and after receiving implant-supported overdenture. The measured sheets were later scanned and analysed using FPD-8010E software. The range of biting forces before the insertion of implants was 80N-122N for the control group and 66-88N for the study group. After the insertion of implants, the range of biting forces increased to 167N-235N for the control group and to 81N-138N for the study group. However, the increase in biting forces after the insertion of implants was not significant for either group. No significant difference was obtained between the two implant systems. The biting forces improved after insertion of implants regardless of which implant system was used. However, the degree of improvement is noticeably related to the original bone quality of the mandible at the insertion regions of implants.

Tooth loss and obstructive sleep apnea signs and symptoms in the US population.

PURPOSE: The aim of this study is to investigate the relationship between tooth loss and signs and symptoms of obstructive sleep apnea (OSA) in a representative sample of the general US population. METHODS: Data were from 7305 men and women aged ≥25 years participating in the 2005-2008 National Health and Nutrition Examination Survey. Tooth loss, occlusal contacts, and denture use were determined by dental examination. Four cardinal OSA signs and symptoms were evaluated by questions based on American Academy of Sleep Medicine criteria. Adults with ≥2 signs/symptoms of OSA were classified at high-risk of OSA. Prevalence ratios (PR) and 95 % confidence limits (CL) from log binomial regression models estimated the strength of association between tooth loss and high-risk for OSA, adjusting for demographic characteristics, body mass index, dentures, and sleep duration. RESULTS: Prevalence of high-risk for OSA increased 2 % for each additional lost tooth (PR = 1.02, 95 % CL, 1.01, 1.03) among adults aged 25 to 65 years. When tooth loss was modeled as an ordinal variable with 0-4 lost teeth as the referent category, adjusted prevalence of high-risk for OSA was as follows: 25 % greater in those missing 5-8 teeth (PR = 1.25, 95 % CL, 1.07, 1.46); 36 % greater in those missing 9-31 teeth (PR = 1.36, 95 % CL, 1.06, 1.73); and 61 % greater in the edentulous (PR = 1.61, 95 % CL, 1.11, 2.33). CONCLUSION: Tooth loss may be an independent risk factor for OSA.

A case of pachyonychia congenita with unusual manifestations: an unusual type or a new syndrome?

A 30-year-old man presented with lesions on his oral mucosa and soles. There were no similar complaints in his family members. The dermatological examination revealed follicular hyperkeratosis on his trunk and upper extremities and flesh-colored, firm cystic lesions on his axillae. He had focal, painful, hyperkeratotic areas sited particularly on both his soles and palms. In addition to these, leukokeratosis and ulcerative areas on buccal, labial mucosa, tongue, and at corners of the mouth, and complete loss of teeth was observed. The proximal layering was revealed on all of his nails. The laboratory investigations produced normal results except the deficiency of immunoglobulin A. The psychiatric examination revealed mild mental retardation. Keratin gene (KRT6a, KRT6b, KRT16, and KRT17) mutations for pachyonychia congenita were negative. He got removable dental prosthesis because of inadequate alimentation. Squamous cell cancer developed on lower lip mucosa during follow-up. We present an individual who had different nail dystrophy, epidermal cysts, mental retardation, blepharitis, complete loss of teeth, and negative keratin gene mutations for pachyonychia congenita and developed squamous cell cancer on the oral leukokeratosis lesions. We think that the present case may be an unusual new type of pachyonychia congenita.

Overdentures on Implants for Better Quality of Life Among the Fully Edentulous Patients - Case Reports.

Global aging population has brought several challenges for their medical systems and total edentulism is one of them. The fabrication of removable acrylic dentures seems to be a simple and cheap treatment solution, but a majority of patients is not satisfied with their functional instability, causing limited diets, mouth soreness, speech and psycho-social problems etc. The results in many studies indicate an impact of oral conditions associated with the full denture wearing on oral-health related quality of life, especially in lower jaw. The reason for improper denture retention could be alveolar ridge bone resorption and numerous studies about this problem are plausible. Bone resorption in lower jaw may turn the alveolar ridge into a flabby soft tissue which is unable to sustain proper denture retention. The implant-retained prosthesis is an alternative treatment option in these situations. Implants will provide retention, stability, function and aesthetics and they are not so expensive solution. The aim of this article is to show solving of retention problems of a lower denture in two different clinical cases using implants and without any special technology.

Influence of the Ethnic Affiliation, Level of Education and Place of Living on Oral Health at Geriatric Population with Total and Partial Dentures in Republic of Macedonia.

INTRODUCTION: Health is the main component of the quality of life, while oral health is component of the general health. The socio-demographic characteristics are one of the important factors for perception of the oral health and the quality of life. The main purpose of this study was to perform an evaluation of the quality of life of geriatric patients (older than 65) with built-in oral prosthetic dentures depending on the ethnic affiliation, level of education and place of living, as socio-demographic characteristics. MATERIALS AND METHODS: The survey was a prospective transversal (cross-sectional) study conducted among 165 institutionally sheltered patients at the Gerontology Institute (inspected group - IG) and 170 patients from the dental specialist clinics (control group CG) at the age of 65 and older. The statistical program SPSS for Windows ver. 13.0 was used for statistical processing. RESULTS AND DISCUSSION: Patients with upper and lower total dentures dominated (43.6% vs. 26.5%). The highest GOHAI score had the other ethnicities of IC (32.08) and Roma of IG (31.00), while the lowest was in the Albanians of CG (25.91). The highest value of 30.15 had the IG of patients living in urban areas. CONCLUSION: The quality of life and oral health of the geriatric patients are at unsatisfactory level, with significant influence of the place of living and insignificant influence of the ethnic affiliation and level of education.

Molecular analysis of oral bacteria in dental biofilm and atherosclerotic plaques of patients with vascular disease.

BACKGROUND: Oral bacteria have been detected in atherosclerotic plaques at a variable frequency; however, the connection between oral health and vascular and oral bacterial profiles of patients with vascular disease is not clearly established. The aim of this study was to evaluate the presence of oral bacterial DNA in the mouth and atherosclerotic plaques, in addition to assessing the patients' caries and periodontal disease history. METHODS: Thirty samples of supragingival and subgingival plaque, saliva and atherosclerotic plaques of 13 patients with carotid stenosis or aortic aneurysm were evaluated, through real-time polymerase chain reaction, for the presence of Streptococcus mutans (SM), Prevotella intermedia (PI), Porphyromonas gingivalis (PG) and Treponema denticola (TD). All patients were submitted to oral examination using the DMFT (decayed, missing and filled teeth) and PSR (Periodontal Screening and Recording) indexes. Histopathological analysis of the atherosclerotic plaques was performed. RESULTS: Most of the patients were edentulous (76.9%). SM, PI, PG and TD were detected in 100.0%, 92.0%, 15.3% and 30.7% of the oral samples, respectively. SM was the most prevalent targeted bacteria in atherosclerotic plaques, detected in 100% of the samples, followed by PI (7.1%). The vascular samples were negative for PG and TD. There was a statistically significant difference (p<0.05) between the presence of PG and TD in the oral cavity and vascular samples. CONCLUSION: SM was found at a high frequency in oral and vascular samples, even in edentulous patients, and its presence in atherosclerotic plaques suggests the possible involvement of this bacterium in the disease progression.

Oral health status and the occurrence and clinical course of myocardial infarction in hospital phase: a case-control study.

BACKGROUND: Periodontitis may contribute to destabilization of atherosclerotic plaque leading to acute coronary syndrome and myocardial infarction (MI). The aim of the paper was to evaluate the state of the oral cavity and test the association between chosen parameters of acute, hospital phase MI in patients aged 60 and younger. METHODS: We examined patients with acute MI, age 60. Control group consisted of matched group of patients with stable angina. Patients enrolled in the study underwent dental, cardiovascular and biochemical examination. Left ventricular ejection fraction (LVEF) was measured during echocardiographic examination, intima-media thickness (IMT) was assessed by ultrasonographic examination at the same time. RESULTS: The case group included 112 hospital patients with acute MI. Patients with acute MI were characterized by higher level of cardiovascular disease risk factors and poor oral health status in comparison to the control group. There was higher prevalence of edentulousness (p = 0.0039) and advanced periodontal disease (APD) (p < 0.0001) in the case group than in the control group. Patients with edentulousness and APD were characterized by the highest levels of fi brinogen, interleukine-6, tumor necrosis factor-a, increased IMT and numerous atherosclerotic plaques. Logistic regression analysis revealed association between biomarkers of myocardial injury, LVEF and chosen periodontal parameter (API, CAL, PDI, BI) and edentulousness. CONCLUSIONS: Poor oral health status, especially periodontal disease may infl uence on the occurrence and clinical course of MI.

Overlap syndrome: a diagnostic dilemma.

We report an interesting case of a young patient who came with a concern for missing teeth and lack of hair on scalp and body. Examination revealed complete absence of teeth, absence of eyebrows, eyelashes and hair over scalp. He was short-statured, had hyperextensible joints and hyperelastic skin, protuberant lips and many other anomalies such that the overall pattern of defects was not recognisable. A wide array of investigations involving the dental and medical faculties were done; however, the final diagnosis could not be reached, since it appeared to involve features of more than one syndrome, thus the name 'overlap syndrome'.

Efeitos do tratamento da síndrome da apneia obstrutiva do sono com aparelho de avanço mandibular em pacientes idosos, desdentados, em uso de próteses dentárias removíveis / Effects on the treatment of Obstructive Sleep Apnea Syndrome with a Mandibular Advancement Device in edentulous elderly patients wearing removable dental prosthesis

O avançar da idade é reconhecidamente um fator de risco para a Síndrome da Apneia Obstrutiva do Sono (SAOS). O motivo dessa constatação está associado à diminuição do tônus da musculatura orofaringeana e à redução da Dimensão Vertical de Oclusão (DVO), esta última atribuída às perdas dentárias. A abordagem odontológica, no tratamento da SAOS, refere-se ao uso de Aparelho de Avanço Mandibular (AAM), que impede a obstrução, parcial ou total, da passagem do ar pela via respiratória alta, durante o sono. Os pacientes desdentados, no entanto, têm sido negligenciados, nos estudos atualmente realizados. Pelo exposto, este trabalho objetivou avaliar os efeitos do tratamento em variáveis polissonográficas, ronco, sonolência, qualidade do sono e ainda os efeitos colaterais pelo uso do AAM titulável, em pacientes idosos e desdentados portadadores de SAOS. A metodologia envolveu inicialmente, cinquenta pacientes, dos quais dezesseis realizaram polissonografia de noite inteira, com gravação do ronco, por meio de um Roncômetro, visando investigação objetiva do sono. Analisaram-se subjetivamente frequência e intensidade do ronco, por questionários. A Escala Visual Analógica de Ronco (EVAR), aplicada ao parceiro de quarto, permitiu, igualmente, que fosse avaliada a intensidade desse sintoma. A sonolência diurna foi quantificada pela Escala de Sonolência de Epworth e a qualidade do sono, pelo Índice de Qualidade do Sono de Pittsburgh.

Confecção individualizada dos AAMs respeitou os princípios biológicos relativos à DVO. Durante uma semana após a instalação, os pacientes utilizavam o AMM sem qualquer avanço mandibular, visando redução de quaisquer desconfortos. Subsequentemente, o protocolo estabelecia titulação gradual e progressiva (30%, 50% e 70%) do aparelho. Transposta a etapa de adaptação, após um período superior a quinze dias, as avaliações iniciais foram repetidas Os efeitos colaterais pelo uso do AAM e adesão ao tratamento foram investigados, a partir de questionários. Doze pacientes completaram o estudo (83,3% mulheres), sendo a media de idade 68 anos e índice de massa corporal médio de 28,3 kg/m2. Os resultados permitiram observar reduções significantes no índice de dessaturação de O2 (17,710,1 eventos/h, p=0,05) e índice de apneia (3,10,9 eventos/h, p=0,02). O uso do AAM evidenciou também diminuições na latência do sono REM, movimentos períodicos de perna, saturação mínima de O2, índice de apneia e hipopneia, na posição supina (p>0,05). O estudo objetivo do ronco apontou redução de 49,522,6 eventos/h (p=0,07). Além do mais, as avaliações subjetivas de frequência (p=0,024) e intensidade (p=0,007) do ronco, EVAR (p=0,003), qualidade do sono (p=0,008), efeitos colaterais e adesão ao AAM foram estatisticamente significantes. Foi possível concluir pela eficácia do tratamento sobre algumas variáveis polissonográficas estudadas, parâmetros subjetivos do ronco e qualidade do sono. Ademais, os sintomas relatados, pelo uso do AAM, reduziram-se ao longo do tempo, o que permitiu, com vantagem, que houvesse maior adesão ao tratamento por parte dos pacientes inseridos nesta pesquisa.

Aging process is well known as a risky factor to Obstructive Sleep Apnea Syndrome (OSAS). Concomitant with this process, the reduction of orofacial and pharyngeal musculature tone, as well as the decrease of Vertical Occlusion Dimension (VOD), the latter attributed to tooth loss, have been considered as probable causal agents involved in OSAS pathogenesis. The Dentistry approach for OSAS treatment is commonly related to the use of Mandibular Advancement Devices (MAD), which could prevent partial or complete upper airway obstruction during sleep. However, this treatment has been scarcely used in toothless patients. The aim of this study was to assess the effects of a titratable MAD in polysomnographic (PSG) variables, snoring, sleepiness, sleep quality and side effects, in edentulous elderly patients with OSAS. Sixteen out of fifty patients assessed have been selected and have undergone an overnight polysomnographic study. Snoring was recorded by using suitable equipment, so that an objective assessment of sleep patterns could be made. The frequency and intensity of snoring have also been subjectively assessed by means of questionnaires. The Snoring Visual Analogic Scale (SVAS), posed to a bed partner, was also assessed to evaluate snoring intensity. Excessive daytime sleepiness and the quality of sleep have also been investigated by Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index, respectively. The patients went through the whole process for individually manufacturing of the MAD following the biological principles of the VDO.

Screening of edentulous patients in a dental school population using the prosthodontic diagnostic index.

PURPOSE: The aim of this study was to classify a number of completely or partially edentulous patients who attended undergraduate clinics at the Dental School of Athens using the prosthodontic diagnostic index (PDI) to identify the complexity of the cases treated by the students. BACKGROUND: There is a scarcity of studies, concerning prosthodontic patients and screening them according to a classification system such as the PDI. MATERIAL AND METHODS: The survey was conducted on 181 patients who attended the clinics for treatment. The PDI categorised the patients into four classes (Class I-IV) according to the severity of certain diagnostic findings. RESULTS: From the 110 completely edentulous patients, 27 patients were in Class I, 21 in Class II, 15 in Class III and 47 in Class IV. From the 71 partially edentulous patients, two were in Class I, 17 in Class II, 29 in Class III and 23 in Class IV. CONCLUSION: Our results showed that the majority of patients were categorised in Class III (partially edentulous) and IV (completely edentulous). This indicates the need to introduce a proper screening tool, such as the PDIs, during the initial examination, to achieve a successful treatment.

Treatment of edentulism: optimizing outcomes with tissue management and impression techniques.

Significant numbers of patients throughout the world seek treatment for edentulism. The trend toward tissue-integrated prostheses has been a monumental step in restoring edentulous patients to function; however, this treatment can be out of reach for those who fail to qualify or those who do not have sufficient resources to afford it. In these cases, conventional dentures remain an important primary course of treatment. Attention to detail when diagnosing, treatment planning, and performing treatment for these patients is still a prime consideration for the best possible outcome. In particular, many experienced denture wearers are afflicted with chronically inflamed denture-bearing mucosa. Clinicians must recognize the need for tissue conditioning, choices of impression materials, and accepted fabrication techniques that can have favorable outcomes when matched with patients who are philosophical and realistic in their expectations. The purpose of this article is to review impression philosophies, associated materials, and methods of tissue conditioning. Retention and stability of the denture bases can be augmented by the routine use of denture adhesive, and indications for use of denture adhesive will be discussed.
