Filter by:This retrospective study investigates the longevity of dentures with SR Phonares II teeth after a wearing period of more than 10 years. The primary objective is to assess the survival rate of dentures with SR Phonares II teeth after more than 10 years. The secondary objectives asses the quality of the dentures concerning aesthetic, functional and biological properties.
Partial or total edentulousness has a significant impact on quality of life both functionally and aesthetically. TBR® Tissue Level Z1 Implants allow the patient to prevent bone resorption and maintain facial tissue and musculature support. At the functional level, the patient who benefits from implant treatment regains normal masticatory function with all the benefits on the quality of life that this can bring him. Due to the osseointegration of the implant and the biocompatibility of the materials used, the implant treatment remains effective in the long term and makes it possible to maintain the aesthetics of the smile.
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.
