Fabrication of a Surgical Guide for Lateral Sinus Augmentation

Area of Science:

• Dentistry
• Oral Surgery
• Medical Imaging

Background:

• Cone-beam computed tomography (CBCT) is crucial for dental implant treatment planning.
• Assessing bone volume and identifying anatomical structures are key challenges, especially in the posterior maxilla.
• Inadequate bone in this region often necessitates sinus augmentation for successful implant placement.

Purpose of the Study:

• To present a method for fabricating a surgical guide.
• To facilitate the transfer of CBCT data into the oral cavity.
• To enable precise placement of a lateral sinus window for augmentation procedures.

Main Methods:

• Utilizing CBCT scans for detailed anatomical assessment.
• Fabricating a custom surgical guide based on CBCT data.
• Employing the surgical guide for accurate intraoral landmark transfer.

Main Results:

• The described method allows for precise transfer of CBCT information.
• Facilitates accurate creation of a lateral sinus window.
• Aids in predictable bone augmentation for dental implants.

Conclusions:

• Surgical guides enhance precision in implant dentistry.
• This technique improves accuracy for sinus augmentation procedures.
• CBCT-guided surgical guide fabrication is valuable for complex implant cases.
