Filter by:The investigators aim to evaluate the biological and mechanical short- and long-term outcome of IL in partially or completely edentulous patients. Moreover, the investigators aim to detect potential influencing risk factors predicting undesirable prosthetic outcome.
The primary objective of the present study is to evaluate the marginal bone level changes occurring in total edentulous patients treated with six or four implants. Secondary objective - overall survival rate - soft tissue status by assessment of bleeding on probing (BoP) and probing pocket depth (PPD) at baseline and after 1,3,5 years - prosthetic survival rates including screw or abutment loosening, framework or veneer fractures
The objective of the present study is to evaluate if loss of multiple adjacent teeth will cause proportionally greater tissue diminution than the loss of single teeth the possibility of counteracting unfavourable ridge modeling after multiple tooth extractions by placing implants in the fresh extraction sites soft tissue alterations at implants and adjacent teeth
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.
