Prospective 10-year cohort study based on a randomized controlled trial (RCT) on implant-supported full-arch maxillary prostheses. Part 1: sandblasted and acid-etched implants and mucosal tissue.

Background: There have been very few long-term controlled studies (i.e., over 5 years duration) focusing on marginal conditions for implants with a sandblasted, large grit, and acid-etched (SLA) surface.

Prospective 10-year cohort study based on a randomized, controlled trial (RCT) on implant-supported full-arch maxillary prostheses. part II: prosthetic outcomes and maintenance.

Background: Long-term follow-up studies (i.e., over 5 years), focusing on prosthetic outcomes and maintenance of implant-supported reconstructions in the edentulous maxilla, are scarce in the literature.

Five-year results from a randomized, controlled trial on early and delayed loading of implants supporting full-arch prosthesis in the edentulous maxilla.

Objectives: The overall aim was to compare the clinical outcomes of early and delayed implant loading in the totally edentulous maxilla during 5 years of function.

Materials And Methods: Twenty-four patients with edentulous maxillae were randomized in two groups and subjected to early (test, n=16) or delayed (control, n=8) loading. A total of 142 implants were placed and 139 implants (Straumann AG) were loaded with full-arch bridges and followed for 5 years.

Three-year data from a randomizd, controlled study of early loading of single-stage dental implants supporting maxillary full-arch prostheses.

Purpose: The aim of this 3-year randomized controlled trial (RCT) was to compare biologic and technical treatment outcomes and patient satisfaction after early (< or = 14 days postimplantation) loaded implants with those of implants loaded after a healing period of 3 to 4 months in the edentulous maxilla.

Materials And Methods: Twenty-four patients with completely edentulous maxillae were randomized into a test group (n = 16) and a control group (n = 8). All patients received 5 or 6 solid screw-type titanium implants with sandblasted, large-grit, acid-etched (SLA) surfaces.

Early loading of ITI implants supporting a maxillary full-arch prosthesis: 1-year data of a prospective, randomized study.

Purpose: This prospective, randomized study investigated the safety, feasibility, and reliability of the early loading of implants in edentulous maxillae.

Materials And Methods: Twenty-four patients with completely edentulous maxillae were randomized into a test group (n = 16) and a control group (n = 8). All patients received 5 or 6 solid screw-type titanium implants.
