Reliability of Using Texture Analysis of Periapical Radiographs Obtained Using Radiovisiography for Assessing Bone...

Area of Science:

• Dentistry
• Oral Radiology
• Implantology

Background:

• Pre-prosthetic implant imaging is crucial for analyzing bone structure and proximity to critical anatomical sites.
• Radiographic analysis aids in quantitative and qualitative assessment for successful dental implant planning.

Purpose of the Study:

• To evaluate the reliability of texture analysis from periapical radiographs obtained via Radiovisiography (RVG) for dental implant planning.
• To determine if RVG imaging is sufficient for assessing bone quality prior to implant surgery.

Main Methods:

• A cross-sectional study involving 50 intraoral periapical radiographs taken with RVG before implant placement.
• Radiographs were assessed by four specialists (Prosthodontist, Periodontist, Oral Surgeon, Oral Radiologist) and compared to tactile perception during pilot drilling.
• The Lekholm and Zarb classification was used as a reference for qualitative bone assessment.

Main Results:

• Examiner accuracy varied, with the Prosthodontist and Oral Radiologist achieving 42% success, and the Periodontist only 26%.
• Accuracy was inconsistent across different anatomical regions, particularly in the anterior maxilla and posterior mandible.
• The study found that RVG radiographs did not consistently meet the required standards for bone quality assessment.

Conclusions:

• Intraoral periapical radiographs acquired through RVG are not sufficiently reliable for assessing bone quality in pre-prosthetic implant planning.
• Texture analysis of RVG images did not provide the desired accuracy for quantitative and qualitative bone evaluation.
• Further research may be needed to explore alternative or supplementary imaging techniques for improved dental implant planning.
