Filter by:On of the main fixed prosthetic options of completely edentulous patients is the screw-retained implant supported prosthesis which was constructed on transmucosal abutments with its encountered problems such as: hardness to make it passively seated with multiple screw fracture and loosening problems and multiple encountered veneer material fracture and so there effect on patient satisfaction with multiple maintenance recalls.so, the investigators want to try a new technique of fabrication which was proposed for reducing the problems of lack of passivity which is the intraoral luting cement technique on titanium bases with reduced screw number but, with luting cement problems as de-cementation and cement biological effects on soft tissues and bone and there effect on number of patient recall visits and maintenance and so there effect on patient satisfaction
Tooth loss impact on daily living, mood and self-perceived well-being. However, psychological impact of teeth loss has not been evaluated. Present study aims to evaluate the psychological conditions of patients pending complete tooth extraction before and shortly after tooth loss using Hospital Anxiety and Depression scale (HAD) and Geriatric Oral Health Assessment Index (GOHAI).
The objective of this explanatory mixed methods study is to compare a novel attachment system (Novaloc) to a traditional alternative (Locator) for single implants in the mandible of edentate elders. The investigators will carry out a randomized cross-over clinical trial comparing Novaloc attachments to Locators for single-implant mandibular overdentures in edentate elders. Participants will be followed for three months with each attachment type; patient-based, clinical and economic outcomes will be gathered. A sample of 26 participants is estimated to be required to detect clinically relevant differences in terms of the primary outcome (patient ratings of general satisfaction). Participants will choose which attachment they wish to keep, then be interviewed about their experiences and preferences with a single implant prosthesis and with the 2 attachments. Data from the quantitative and qualitative assessments will be integrated through a mixed-methods explanatory strategy. A last quantitative assessment will take place after 12 months with preferred attachment; this latter assessment will enable the observation of attachments' long-term wear and maintenance events.
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by one and two implants and the mandibular fixed prosthesis retained by four implants, based on a randomized clinical trial.
Dental implants are often the preferred treatment option and in some clinical scenarios they are considered the standard of care to restore missing or damaged teeth, due to the limitations of conventional treatments. For fully edentulous subjects, conventional tissue-supported dentures in some cases are associated with severe subjective complaints and difficult adaptation, mainly the mandibular denture, resulting in limited function and detrimental effects on oral health-related quality of life, especially for older patients. The use of implants to retain a mandibular denture (overdenture) has been recommended as a suitable and low-cost alternative to improve denture stability, with positive effects on oral comfort and function. The two-implant mandibular overdenture has been considered an effective design to achieve clinical benefits for patients. However, the main problem facing two-implant overdenture is the high cost of implantation and the relative complexity of the surgical intervention, so the use of a single midline implant to retain a mandibular overdenture was suggested as a more viable solution for reducing costs and complexity of treatment with similar benefits compared to solutions with higher number of implants. Nevertheless, there are few studies that compared the performance of different retention systems and their effects on patient-centered outcomes, such as satisfaction with the dentures, oral health-related quality of life, individual preferences and other subjective ratings of clinical outcomes. Thus, the aim of this randomized clinical trial with a crossover design is to investigate the changes in clinical and patient-reported outcomes following the use of different retention systems for a single implant-retained mandibular overdenture Hypothesis: it was hypothesized that clinical and patient-reported outcomes of a single-implant mandibular overdenture is dependent on the type of retention system, and patients have distinct preferences in relation to different attachments
BACKGROUND: The literature has shown that simplified methods for complete denture fabrication can be as effective as the traditional techniques, but with less expenditure of time and resources, without prejudice to the patients. However, the effectiveness of these simplified methods for patients with more complex medical conditions haven't been deeply explored. OBJECTIVES: To evaluate the effectiveness of a proposed simplified method for complete dentures fabrication for patients with severely resorbed mandibular alveolar bones. METHOD: edentulous patients requesting treatment with bimaxillary complete dentures in a university clinic will be rehabilitated following a simplified technical proposal, being divided randomly into two groups according to the mandibular arch molding technique. In group A, a single impression with alginate through pre-fabricated trays will be performed, while patients allocated in group B will receive a second molding with a more complex technique. After 3 and 6 months, besides important clinical parameters, it will be investigated aspects related to patient's perceptions about the success of treatment. The study will be conducted with a minimum of 30 participants per group, and comparisons between the two groups will be made by means of tests suitable for distribution of data.
This study is a randomized clinical trial to compare patient satisfaction and prosthetic outcomes with lower dentures retained by one or two implants. The investigators long-term objective is to establish evidence of the cost-effectiveness of a single implant intervention for improving tolerance to complete dentures. The investigators MAIN AIM will be to investigate patient satisfaction between and within groups with mandibular dentures retained by one or two implants over five years, and SECONDARILY to investigate the survival of implants, and the frequency of events to maintain the dentures and prosthetic attachments as clinically serviceable. Furthermore, multivariate analysis can assess the prediction of patient satisfaction with implant dentures based on various possible factors including age, health, demography and socioeconomic status, number of implants, and maintenance needs. Patient satisfaction will be measured by means of Visual Analogue Scales (VAS) including a measure of overall satisfaction and various specific aspects of satisfaction such as appearance, stability and comfort of the dentures. The CENTRAL HYPOTHESIS is that mandibular complete dentures retained by single implants are at least as satisfying to patients over a five years period as those retained by two implants for the same period. The SECONDARY HYPOTHESES are that: i) there is no difference over five years between groups in the survival of original implants, or in the number of events for maintenance of the dentures or implant attachments; and ii) using each treatment group as it's own control, there is no change in patient satisfaction with lower dentures retained by either one or two implants during the five year loading period.
The objective of this study is to compare the canine guidance (CG) and bilateral balanced occlusion (BBO) on denture satisfaction and kinesiographic parameters of complete denture wearers, by means of a cross-over trial. Edentulous patients will receive new maxillary and mandibular complete dentures and, after the intraoral adjustments and adaptation period, will randomly receive a sequence of occlusal schemes: BBO followed by CG, or CG followed by BBO.
This study aims to compare mandibular overdentures retained either by mini or standard size implants as a treatment for edentulous adults, in terms of patient-reported satisfaction and oral health-related quality of life. We will also evaluate post surgical discomfort, the success rate of prostheses and implants in the long term, denture quality and costs.
BACKGROUND: The fabrication of complete dentures traditionally involves a series of complex technical procedures. Those procedures include two impressions for each jaw, the registration of the relationship between the upper teeth and the patient's head and usually two appointments for tooth try-in. However, recent studies have questioned the real need for such complex procedures. Simplified methods could have similar results if compared with conventional ones, and dentures would be delivered faster and with lower costs. OBJECTIVES: This study aims to compare the effectiveness complete dentures fabricated with a simplified or conventional method. METHODS: Eighty edentulous patients who requested treatment by maxillary and mandibular complete denture in a public dental clinic inside the University of Sao Paulo - Ribeirão Preto Dental School will be randomly divided into two groups. Group S will receive new dentures fabricated by a simplified method, whereas Group C will received new dentures according to a conventional method. Participants will complete a questionnaire for denture satisfaction and the oral health-related quality of life, 3 and 6 months after treatment. At the same time, a specialist in dental prostheses will evaluate the quality of new dentures.
