ClinConnect Summary

This clinical trial is looking at two different ways to lift and support the thin membrane inside the maxillary sinus (a cavity in the upper jaw) when preparing the area for dental implants. The goal is to help build up the bone in the upper jaw to allow secure placement of implants where teeth are missing. In one group, doctors will use a small titanium mesh fixed with screws to gently lift and hold the membrane in place. In the other group, stainless steel screws or pins will be used to support the membrane. Both groups will receive a special blood product called platelet-rich fibrin (PRF) to help with healing.

Adults between 18 and 60 years old who need dental implants in the upper jaw but have less than 5 mm of bone height at the implant site may be eligible. Participants should have good oral health and agree to take part in the study. Those with certain health problems, active infections, heavy smokers, or untreated gum disease won’t be included. If you join, you can expect a surgical procedure where the sinus membrane is carefully lifted and supported using one of the two methods, followed by dental implant placement later on. This study aims to find out which method better supports healing and successful implant placement.

• • Patients with one or more teeth requiring implant supported dental restoration in atrophic maxilla.
• • Alveolar bone height less than 5 mm at the defective site.
• • Good oral hygiene.
• • Patient's consensual agreement to be enrolled in the study.
• Exclusion Criteria:
• • Medically compromised patients with conditions contraindicating surgery (eg. uncontrolled diabetics, bisphosphonate intake, radio or chemotherapy).
• • Patients with active infection at or related to the site of surgery (eg. acute sinusitis).
• • Heavy smokers.
• • Patients not indicated for an implant supported restoration at the time of enrollement (eg. active/untreated periodontal disease). (Patients developing any medical condition that interferes with the outcomes after enrolment in the study will be excluded).
