Why guided when freehand is easier, quicker, and less costly?

Area of Science:

• Dental Implantology
• Computer-Assisted Surgery
• Prosthodontics

Background:

• Computer-assisted implant planning (CAIP) offers benefits like improved aesthetics, patient comfort, and immediate restoration.
• CAIP may provide enhanced implant survival and success rates, particularly in Types III and IV bone, compared to freehand techniques.
• This retrospective analysis investigates the potential advantages of CAIP in various bone qualities.

Purpose of the Study:

• To evaluate the 1-year survival and success rates of dental implants placed using computer-assisted techniques.
• To assess the impact of CAIP on primary implant stability across different bone densities.
• To examine radiographic bone level changes at 1 year post-implantation.

Main Methods:

• Retrospective analysis of 80 implants in 27 patients over 7 years using CAIP.
• Implants supported single teeth, bridges, and complete arch restorations.
• Primary stability assessed via insertion torque, resonance frequency analysis (ISQ), and Periotest.

Main Results:

• 100% implant survival and success rate at 1 year.
• Radiographic analysis showed bone level change < 2 mm from the platform at 1 year.
• Consistent primary stability measurements (40 Ncm torque, 76 ISQ, -3 Periotest) achieved regardless of bone density.

Conclusions:

• CAIP enables precise planning and high primary stability, even in less dense bone.
• This technique enhances predictability and may improve implant outcomes.
• Restoratively driven diagnosis and planning with CAIP lead to successful implant integration.
