Changes in the pre-surgical treatment planning using conventional spiral tomography

Area of Science:

• Dentistry
• Oral Surgery
• Radiology

Background:

• Accurate pre-surgical planning is crucial for successful dental implant therapy.
• Conventional radiography (periapical, panoramic) provides initial assessments.
• The added value of cross-sectional tomography in refining treatment plans requires investigation.

Purpose of the Study:

• To evaluate the impact of conventional spiral tomography on pre-surgical treatment planning for dental implants.
• To determine variations in planning parameters after incorporating tomographic data.

Main Methods:

• Twenty-nine patients undergoing implant therapy were included.
• Pre-surgical planning for 120 implant sites was performed twice: initially with conventional radiography and subsequently with added tomography.
• Evaluated parameters included implant length/width, and the need for bone grafting or other surgical procedures.

Main Results:

• Implant length and width planning remained largely unchanged (60.2% and 87.2%, respectively).
• Conventional spiral tomography significantly altered the planned need for bone grafting (15.8% of cases) and other surgical procedures (5.3% of cases).
• These changes were significant across all maxillary and mandibular regions.

Conclusions:

• Conventional spiral tomography is a valuable tool in pre-surgical dental implant planning.
• It enhances clinician confidence in determining the necessity for additional procedures like bone grafting and sinus lifts.
• Tomography refines treatment strategies, particularly in complex cases.
