Factors affecting retention and stability of complete dentures
Journal of Prosthetic Dentistry, 1962
Lammie,l Skinner,2 and Stanitz3 have already determined conclusively the part played by the thickness of the fluid film or salivary meniscus which, in varying thicknesses, exists between the impression surfaces of the denture and the total area of tissue it contacts in the mouth. This total area of contact and the fluid film thickness bear a direct relation to the retentive qualities of a denture and have 2CA been described3 in the equation F = -, in which F is the force necessary to dislodge the denture, C is the coefficiei of the surface tension of water, which remains a constant in this equation, A is the total area of tissue surfaces which support the denture, including the facial surfaces of the denture (this is a variable), and a is the fluid film thickness between the denture and the tissues (this is also a variable). Generally, this means that the greater the area (A) of a denture and the smaller the fluid film (a) between the denture and the tissues, the greater is the force (F) necessary to dislodge that denture.4 PURPOSE The purpose of this study was to see how the area of the impression surface of a denture could be effectively increased and how the fluid film or salivary meniscus could be decreased, thereby fulfilling the necessary relationship in the equation that can be effectively controhd by the dentist to increase the force necessary to dislodge the denture.
Occlusal Considerations in Complete Dentures Chewing Efficiency and Patients' Satisfaction
here are two well-established facts about com-T plete dentures. The first is that the majority of complete denture patients have significantly decreased chewing efficiency compared to dentate subjectsJM',B,97,98 and patients with over-denture91 or implant-supported reconstructions.50,62 The second fact is that the majority of complete denture patients are satisfied with their denture no matter how good it is, and approximately 10% to 15% are dissatisfied even if their denture is perfectly constructed.5 These two facts erase the question of how relevant occlusion is for chewing efficiency and patients' satisfaction. The question is pertinent, because a good occlusion is considered by many cIinicians to be of paramount importance for the success of complete dentures.

Statement of problem. Some complete denture wearers report difficulty with daily activities, especially activities related to denture retention and stability. However, no standard criteria are available for professionally based assessment of complete denture quality. Purpose. The purpose of this clinical study was to determine the association between professionally based assessment of complete denture quality, evaluated by conventional and Chulalongkorn University (CU)-modified Kapur criteria and multiple patient-based outcomes: oral health-related quality of life (OHRQoL), eating satisfaction, and masticatory performance. The sensitivity and specificity of these criteria in estimating the outcomes were investigated.
INFLUENCE OF THE WEAR TIME OF COMPLETE DENTURE ON SWALLOWING, CHEWING, AND MYOFUNCTIONAL POSTURAL CONDITIONS (Atena Editora), 2022
Purpose. Complete denture is a therapeutic modality widely used by edentulous patients. However, with the years, its wear may have harming effects regarding the phono-articulatory organs and the swallowing/chewing functions. In this investigation, the relationship between the time of denture use and the swallowing and chewing difficulties was assessed, as well as these people’s orofacial myofunctional postural conditions. Material and Methods. Individuals of both sexes, completely edentulous, wearing conventional maxillary and mandibular conventional complete denture acrylic resin were recruited from August 2018 to February 2020, from School of Dentistry of Ribeirão Preto of the University of São Paulo (USP) and distributed into three groups according to the time of denture use: G1 – 1 to 6 months (n=8); G2 – 7 to 18 months (n=12); G3 – 18 to 120 months (n=9).Then, they were interviewed and assessed with the Orofacial Myofunctional Evaluation (OMES). Pearson correlation test (α=.05) was used to correlated the time of denture with the findings in the interview and protocol. Results. A total of 29 individuals were assessed, being 14 women and 15 men with aged 43 to 83 years (mean 63 years). One (3.4%) participant had complaints related to swallowing dry foods, while 3 (10.3%) had complaints related to swallowing hard foods. However, there was no correlation with the time of denture wear. Concerning the orofacial myofunctional postural aspects and conditions, no significant differences were observed for the phono-articulatory organs: lips, tongue, and cheeks, as well as for the stomatognathic functions of swallowing and chewing related to the time of denture wear. Conclusion. The time of denture wear did not influence the complaints, neither did it interfere with the postural aspects and conditions of the phono-articulatory organs, or the patients’ swallowing and chewing.
Factors Associated With Successful Denture Therapy
Journal of Prosthodontics, 1996
The purpose of this investigation was t o evaluate complete denture patients at pretreatment and postinsertion, 6 months and 18 months after denture delivery in order to develop an explanatory model of successful denture therapy to better understand patient acceptance of complete dentures. Materials and Methods: Sixty complete-denture patients treated at a dental student clinic were followed through denture therapy and for 18 months thereafter. Subjects were examined and completed pretreatment questionnaires and posttreatment interviews. Three outcome measures of denture success were tested, and factors considered substantive in achieving a successful denture outcome were examined using multivariate analyses. Results: At post-insertion, 76.7% of subjects were satisfied with their dentures, 74.6% said their expectations were met, and 66.7% said they adjusted easily t o their new dentures; reports at 6 and 18 months were similarly high. Logistic regression findings suggest that psychological and interpersonal factors are more important determinants of denture satisfaction than anatomic or clinical factors. Conclusions: Subject characteristics including age, gender, race, income level, education, marital status, and maxillary and mandibular anatomy were not significantly associated with denture success as defined by the three outcome measures used in this study. Although these variables may represent important co-factors in the patient's acceptance of dental services and may affect the way a patient perceives dental care outcomes, statistically significant relationships were not found within our sample. Psychosocial variables, such as pretreatment expectations, satisfaction with the dental care received, and mental health showed a stronger relationship t o a successful outcome.

The aim of the present study was to assess the effect of a denture adhesive (DA) on patient satisfaction and kinesiographic parameters of complete denture wearers by a cross-over study. Fifty edentulous patients received a set of new complete dentures. After an adaptation period, the participants were enrolled in the trial and randomized to receive a sequence of treatment protocols: Protocol 1-DA use during the first 15 days, followed by no DA for the next 15 days; Protocol 2-no DA during the first 15 days, followed by use of DA for the next 15 days. Outcomes were assessed after 15 days of each sequence of treatment. A questionnaire was used to assess the patients´ satisfaction. A kinesiograph was used to record mandible movements and patterns of maxillary complete denture movement during chewing. The Wilcoxon test (α=0.05) and a paired sample t-test (α=0.05) were used to compare satisfaction levels and kinesiographic data, respectively. Use of DA improved the overall level of patient satisfaction (p<0.001). The kinesiographic recordings revealed a significant increase (1.7 mm) in vertical mandible movements (p<0.001) during chewing and a lower (0.3 mm) vertical intrusion of the maxillary complete dentures (p=0.002) during chewing after using the DA. Use of DA in complete denture wearers improved the patients´ satisfaction and altered mandible movements, with increases in vertical movements during chewing and less intrusion of maxillary complete dentures.
