Must have
Residual bone height under the maxillary sinus between 5 to 7 mm and a width of at least 7 mm, as measured on cone beam computer tomography (CBCT) scans.
Neighboring teeth to the planned implant must have natural root(s) or implant supported restoration.
Must not have
Systemic or local disease or condition that could compromise post-operative healing and/or osseointegration
Uncontrolled pathologic processes in the oral cavity
Timeline
Screening 3 weeks

Summary

This trial will compare the outcomes of 5mm and 10mm implants placed in sinus-grafted sites. The primary outcome is bone loss, and the secondary outcomes are surgical time and patient-reported outcomes (satisfaction and post-operative pain).

Who is the study for?
This trial is for adults aged 20-70 needing a dental implant in the upper jaw, who are generally healthy with controlled diabetes if present. They should have good oral hygiene and enough bone under the sinus for the implant. Smokers of more than 10 cigarettes/day, heavy drinkers or drug users, pregnant women, and those with conditions affecting healing aren't eligible.
What is being tested?
The study compares short (5 mm) versus long (10 mm) dental implants in terms of how well they stay in place over time. It will also look at differences in bone loss around the implants, surgical duration, and patient satisfaction including pain after surgery.
What are the potential side effects?
While not explicitly stated here, common side effects from dental implant surgery can include swelling, bruising, minor bleeding and pain at the implant site. There may be risks associated with longer vs shorter implants that this study aims to uncover.
