Three-year Data from a Randomized, Controlled Study of Early Loading of Single-Stage Dental Implants Supporting Maxillary Full-Arch Prostheses

Three-year Data from a Randomized, Controlled Study of Early Loading of Single-Stage Dental Implants Supporting Maxillary Full-Arch Prostheses


PMID: 16634495

Purpose: The aim of this 3-year randomized controlled trial (RCT) was to compare biologic and technical treatment outcomes and patient satisfaction after early ( 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. In total, 142 implants were placed and 139 implants were loaded with full-arch prostheses. Clinical assessments were obtained at loading and after 3, 6, 12, 24, and 36 months. Radiographs of implants and existing teeth were taken at loading; after 6, 12, 24, and 36 months; and at 12, 24, and 36 months, respectively. Results: The cumulative implant success rate 3 years after loading was 100%. At the 3-year examination the mean (P .005), distal (P .005), and mesial (P > .05) crestal bone levels were better in the test group. No significant differences between the test and control groups were noted for any other outcome measure. The most common adverse event in both groups was tooth-crown fracture. Discussion: A review of the literature, both printed and electronic, revealed no study fulfilling the criteria of an RCT dealing with the early loading of maxillary full-arch prostheses. This study fulfills those criteria. Conclusion: In this study population it has been concluded that the early (approximately 2 weeks) loading protocol is a viable alternative to the standard (3 to 4 months) protocol in the rehabilitation of a completely edentulous maxilla with a complete implant-supported fixed prosthesis.
