Graftless sinus lift simultaneously with dental implants placement: a prospective cohort study

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Sinus augmentation is crucial for posterior maxilla dental implants.
• Graftless techniques offer potential advantages but require robust clinical validation.
• Simultaneous implant placement and sinus elevation are complex procedures.

Purpose of the Study:

• To evaluate the clinical outcomes of a graftless sinus lift technique.
• To compare graftless sinus elevation with traditional bone grafting.
• To assess implant survival, bone gain, and complications over 5+ years.

Main Methods:

• Prospective cohort study over 8 years.
• 74 patients in the graftless sinus membrane elevation group.
• 15 patients in the bone-grafted control group.

Main Results:

• Graftless group achieved a 97.76% implant success rate.
• Grafted control group had an 86.6% implant success rate.
• Residual bone height significantly impacted implant success in both groups.

Conclusions:

• Graftless sinus floor elevation is a safe and reliable procedure.
• The technique is suitable for simultaneous dental implant placement.
• Prospective design and long-term follow-up support findings.
