An Evaluation of Integration Success and Maintenance of Short Implants in Maxillas Needing Sinus Augmentation
A study testing Dental Implant (Nanotite) in people with Tooth Disease and Partial Edentulism, run by ZimVie at 1 site in Spain.
Trial summary
This prospective randomized study will evaluate the integration success while supporting a prosthesis for short implants placed into maxillary sites having minimal bone height that would otherwise need sinus augmentation. The resources utilized during treatment will be assessed. Read more about this study

About this study
Official title: A Prospective, Multicenter, Randomized Multicenter Study of Short Implants Used to Obviate the Need for Sinus Augmentation: an Assessment of Clinical Outcomes and Resource Allocation.
This prospective randomized study will evaluate the integration success while supporting a prosthesis for short implants placed into maxillary sites having minimal bone height that would otherwise need sinus augmentation. The resources utilized during treatment will be assessed.
Study (null) hypothesis: the overall benefit of using short length implants to avoid sinus augmentation procedures will offset differences in the cumulative implant survival rates observed between treatment groups.
Read the detailed description
In this randomized study, patients needing restorations in the posterior maxilla will be randomly assigned to the short implant group (test) or the standard length and augmentation group (control). All implants will be placed using a two-stage approach with healing abutments placed at three months and temporary prosthesis at four months following implant and/ or sinus augmentation surgery. Time, materials, and efforts associated with treating test and control cases will be documented to allow an assessment of the costs incurred with each approach.
