Purpose of the Study: To evaluate measurable outcomes, specifically angular deviation, linear deviation, surgical time, and implant survival, when comparing guided versus freehand implant placement.
Methods: A literature review was conducted using systematic reviews, randomized controlled trials, and studies published in the Journal of Oral Implantology and other peer-reviewed journals from the last 15 years. Outcomes assessed included mean angular deviation (°), linear deviation at implant platform and apex (mm), average surgical time, and implant survival rates.
Results: Guided placement consistently improves accuracy. Recent randomized controlled trials confirm angular deviation of < 1° and linear deviations around 0.3–0.5 mm in guided immediate implant placement, compared with deviations exceeding 6° and >1 mm in freehand techniques. Across multiple studies, static and dynamic guidance also demonstrated lower variability in both coronal and apical positioning. Surgical time is often reduced in guided procedures, though preoperative planning increases overall treatment time. Importantly, implant survival rates remain comparable between guided and freehand approaches, exceeding 95% in most studies.
Conclusion: Guided surgery enhances accuracy and intraoperative efficiency, but survival outcomes remain similar to freehand placement. Clinical decision-making should be guided by case complexity, anatomical limitations, and esthetic demands.
