Lateral Window Maxillary Sinus Elevation With Simultaneous Implant Placement: A Step-by-Step Surgical Technique.

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Tooth loss in the posterior maxilla leads to sinus pneumatization, decreasing vertical bone height.
• Reduced bone height compromises dental implant placement feasibility.
• The lateral window sinus elevation technique is a method to address this bone deficiency.

Purpose of the Study:

• To present a detailed, step-by-step surgical technique for lateral window maxillary sinus elevation.
• To describe simultaneous dental implant placement with bone grafting and membrane coverage.
• To provide a guide for clinicians performing sinus augmentation in the posterior maxilla.

Main Methods:

• Surgical access via a lateral bony window into the maxillary sinus.
• Elevation of the Schneiderian membrane.
• Placement of particulate bone graft material in the subantral space.
• Simultaneous insertion of a dental implant to achieve primary stability.
• Coverage with a resorbable barrier membrane and primary wound closure.

Main Results:

• The described technique facilitates bone augmentation in the posterior maxilla.
• Simultaneous implant placement is achievable with adequate primary stability.
• The procedure allows for predictable sinus floor elevation.

Conclusions:

• The lateral window sinus elevation technique is a viable surgical option for bone augmentation in the posterior maxilla.
• This method enables simultaneous dental implant placement in augmented bone.
• The technical report provides a structured approach for clinicians performing this procedure.
