Three-dimensional guidance system for implant insertion: Part II. Dual axes table--problem solving.

Area of Science:

• Dental Implantology
• Surgical Navigation
• Radiographic Imaging

Background:

• Accurate dental implant placement is crucial for successful outcomes.
• Traditional methods can lack precision in three-dimensional positioning.
• Need for improved guidance systems in implant surgery.

Purpose of the Study:

• To present a novel three-dimensional guidance system for dental implant insertion.
• To enhance the accuracy of implant placement using radiographic and cast-based techniques.
• To provide a practical method for transferring planned implant positions and orientations to surgical guides.

Main Methods:

• Fabrication of a radiographic guide with a radiopaque vertical orientation pin on a stone cast.
• Utilizing cross-sectional and panoramic reformatted CT scan images.
• Employing a dual-axes base to transfer implant starting points and inclinations to surgical drill guide tubes.
• Performing pilot osteotomy based on transferred surgical guide data.

Main Results:

• The true vertical orientation pin accurately identifies implant locations and facilitates osteotomy planning.
• The system allows for precise measurement of implant angulation.
• Accurate transfer of buccolingual and mesiodistal inclinations to the surgical guide.
• Successful transfer of exact starting points and inclinations to the alveolar bone via pilot osteotomy.

Conclusions:

• The developed three-dimensional guidance system offers high accuracy and practicality for dental implant insertion.
• This technique improves the precision of implant positioning and angulation.
• It provides a reliable method for translating virtual implant plans into surgical reality.
