Elevating maxillary sinuses for dental implants

Transalveolar Crest Parietal Sinus Floor Lift and Secondary Lift for Postoperative Improvement of Neonatal Bone Mass in Sinus: a Prospective Clinical Study in the Posterior Maxillary Region

Not applicable Interventional Nanfang Hospital, Southern Medical University · NCT06106321

This study is testing a procedure to lift the maxillary sinuses to see if it helps people get dental implants in the back of their mouths.

What this trial studies

This clinical trial involves approximately 40 participants who will undergo a maxillary sinus floor lift procedure to facilitate dental implant placement in the posterior maxillary region. Participants will be screened for eligibility and will receive either the experimental or control treatment based on the study protocol. The study aims to evaluate subjective perceptions and changes in soft and hard tissues at 3 months, 6 months, and 1 year post-implant placement. All subjects will provide informed consent and undergo necessary preoperative examinations.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been missing posterior maxillary teeth for at least 3 months and meet specific radiological criteria for sinus lift procedures.

Not a fit: Patients with uncontrolled diabetes, heavy smokers, or those with a history of sinus disease or previous sinus surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the success rates of dental implants in patients with tooth loss in the posterior maxillary region.

How similar studies have performed: Other studies have shown success with similar maxillary sinus lift procedures, indicating a potential for positive outcomes in this area.
