Active clinical trials for "Mouth, Edentulous"

This post-market study is to show that dental implants with a SLActive® surface (SLActive® implants) show non-inferior clinical performance compared to dental implants with a SLA® surface (SLA® implants). The primary hypothesis is that 12 months after implant loading, the bone loss around the SLActive® implants will not be appreciably greater than around the SLA® implants. The occurrence of adverse events and device deficiencies will also be recorded to confirm once more the safety of the Straumann® Bone Level Tapered (BLT), Roxolid® implant. Osseointegration and anti-inflammatory potential of SLActive® implants will be evaluated in the study as secondary endpoints.

The aim of the current study is to assess the effect of two types of attachments (Locator, Novaloc) on the supporting structures both mechanically using stress strain analysis and biologically through measuring bone height using cbct.

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.

Multicenter study to assess the survival and the success rates of six short implants (ANKYLOS C/X 6.6 mm) in the edentulous maxilla supporting fixed full-arch bridges after 5 years in function.

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 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.

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 this study is to evaluate the survival of narrow dental implants (≤ 3,5 mm) in multiple fixed prostheses in comparison with standard diameter dental implants (≥ 3,75 mm) after 5 years of follow-up. The hypothesis of the study is that narrow dental implants under the evaluated conditions, have the same survival rate and clinical performance than the standard diameter implants.

The aim of this study is to evaluate: Primary objective The primary objective of the present study is to evaluate the marginal bone level changes when partially edentulous patients, treated with implants, received a multiunits screw retained fixed dental prosthesis with a Co/Cr milled framework with an Internal or External connection. 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.
