Crestal sinus lift by using a mini-invasive procedure: a case series

Area of Science:

• Dental Implantology
• Oral Surgery
• Regenerative Medicine

Background:

• Maxillary sinus lifts are crucial for dental implant placement in cases of insufficient bone volume.
• Traditional sinus lift procedures using osteotomes can lead to complications from percussive forces.
• There is a need for atraumatic and predictable sinus lift techniques.

Purpose of the Study:

• To present a case series utilizing the SinCrest procedure for maxillary sinus lifts via a crestal approach.
• To evaluate the efficacy and safety of this atraumatic technique.
• To demonstrate implant placement during the same procedure as the sinus lift.

Main Methods:

• The SinCrest procedure was employed in three cases of partial edentulism with inadequate maxillary bone volume.
• Surgical templates guided the sinus lift and simultaneous implant placement.
• Radiographs were taken after 6 months to assess surgical success.

Main Results:

• The SinCrest technique allows precise, controlled sinus floor elevation without perforating the Schneiderian membrane.
• It minimizes the risk of complications associated with forceful osteotome use.
• The procedure requires a smaller flap and osteotomy, leading to reduced healing time and improved patient comfort.

Conclusions:

• The SinCrest procedure is a safe, controlled, and atraumatic alternative for maxillary sinus lifts with a minimum of 5 mm residual bone height.
• It offers a less invasive option compared to traditional methods.
• This technique simplifies the procedure and enhances patient outcomes.
