Simple technique using ridge spreaders to safely perform a transcrestal sinus floor elevation: a technical note.

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Transcrestal sinus floor elevation (tSFE) is crucial for vertical bone augmentation in the posterior maxilla.
• The conventional tSFE technique carries a risk of Schneiderian membrane perforation due to its blind nature.

Purpose of the Study:

• To present a simple, controlled technique for tSFE using readily available ridge spreaders.
• To demonstrate a method that avoids instrument entry into the maxillary sinus, reducing perforation risk.

Main Methods:

• A novel tSFE technique utilizing ridge spreaders is described.
• The procedure emphasizes slow, controlled bone manipulation without direct sinus cavity instrumentation.
• The technique is illustrated in a clinical case with challenging anatomical features.

Main Results:

• The presented technique allows for tSFE without perforating the Schneiderian membrane.
• It utilizes existing surgical armamentarium, avoiding specialized drills or uncomfortable osteotomes.
• Successful augmentation was achieved in a case with limited bone height and oblique sinus floor.

Conclusions:

• This ridge spreader technique offers a safer and simpler alternative for tSFE.
• It enhances predictability and patient comfort in sinus lift procedures.
• The method is suitable for complex cases requiring vertical bone augmentation for dental implants.
