Short Dental Implants (5 mm) Versus Long Dental Implants (10 mm)

Short Dental Implants (5 mm) Versus Long Dental Implants (10 mm) in Combination With Sinus Floor Elevation: A Randomized Clinical Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 34 (actual)
• Sponsor: University of Michigan · Academic / Other
• Sex: All
• Age: 20 Years – 70 Years
• Healthy volunteers: Accepted

Summary

The purpose of this study is to evaluate the survival rate of 5 mm short implants compared to longer implants (10 mm) placed in sinus-grafted sites. Primary aim: Compare bone loss between the two groups Secondary aim: Compare surgical time and patient-reported outcomes (satisfaction and post-operative pain)

Detailed description

34 patients requiring an implant to replace an upper missing tooth in the premolar or 1st molar area with a bone crest height from 5 to 8 mm will be recruited for this trial. Patients will be randomized to either the test (5-mm implant) or control group (10-mm implant) using a computer-generated randomization list . 17 patients will receive a sinus lift procedure, bone graft, and 10 mm implant while the other 17 patients will receive a 5 mm short implant.

Conditions
