  Purpose

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.


Condition Intervention
Tooth Disease Partial Edentulism Device: Dental Implant (Nanotite)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
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.

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Integration Success of Implant [ Time Frame: 3 years ]
    Number of enrolled and treated patients with integrated implants (no mobility detected) at time of analysis.


Secondary Outcome Measures:
  • Cost Analysis [ Time Frame: 3 years ]

Enrollment: 37
Study Start Date: February 2009
Study Completion Date: July 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Dental implant (Nanotite)
Dental implants of short length placed without sinus lifts
Device: Dental Implant (Nanotite)
Root form titanium dental implant
Other Name: Nanotite
No Intervention: Control group
Dental implants of standard length placed simultaneously with sinus augmentation

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.
