This study aimed to evaluate and compare the accuracy and safety of indirect sinus lift and immediate implant placement in maxillary posterior partially edentulous sites, using dynamic navigation versus freehand placement. The study also aimed to compare the procedural time for both these techniques and the patient satisfaction following treatment.
This split-mouth study was conducted over two years, involving 28 patients, with a total of 64 implants placed. After data collection, 62 implants were included in the final analysis. Each patient required bilateral indirect sinus lifts with immediate implant placement. The study compared angular deviation, deviation at entry, and Apex Deviation between Group A (Dynamic Computer-Assisted Implant Surgery, dCAIS) and Group B (freehand placement).
The study revealed a statistically significant difference across all three measured parameters between the two groups. For angular deviation, the DNS group demonstrated a mean of 2.768°, which was substantially lower than the 11.094° observed in the freehand group. The deviation at entry was significantly lower in the DNS group, averaging 1.510 mm compared to 2.687 mm in the freehand group. The mean apex deviation in the DNS group was 2.719 mm, markedly less than the 3.913 mm recorded in the freehand group.
Real-time dynamic navigation in implant surgery offers greater accuracy and safety compared to freehand techniques, particularly in complex procedures such as indirect sinus lift and immediate implant placement. The technology significantly reduces deviations, enhancing clinical outcomes in dental implantology.
Real-time dynamic navigation in implant surgery improves clinical outcomes by offering enhanced accuracy and safety, particularly in complex procedures like indirect sinus lifts and immediate implant placements. By minimizing deviations during surgery, this technology reduces the risk of complications, contributing to more predictable and successful dental restorations.
本研究旨在评估和比较在上颌后牙部分缺牙部位采用动态导航与徒手植入进行间接窦底提升和即刻种植的准确性和安全性。该研究还旨在比较这两种技术的操作时间以及治疗后的患者满意度。
这项双侧对照研究历时两年，涉及28名患者，共植入64颗种植体。数据收集后，最终分析纳入62颗种植体。每位患者均需进行双侧间接窦底提升并即刻种植。该研究比较了A组（动态计算机辅助种植手术，dCAIS）和B组（徒手植入）之间的角度偏差、入口处偏差和根尖偏差。
研究显示两组在所有三个测量参数上均存在统计学上的显著差异。对于角度偏差，动态导航组的平均值为2.768°，显著低于徒手植入组观察到的11.094°。动态导航组入口处偏差明显更低，平均为1.510毫米，而徒手植入组为2.687毫米。动态导航组的平均根尖偏差为2.719毫米，明显小于徒手植入组记录的3.913毫米。
与徒手技术相比，种植手术中的实时动态导航提供了更高的准确性和安全性，特别是在间接窦底提升和即刻种植等复杂手术中。该技术显著减少了偏差, 提高了牙种植学的临床效果。
种植手术中的实时动态导航通过提供更高的准确性和安全性改善了临床效果，特别是在间接窦底提升和即刻种植等复杂手术中。通过在手术过程中最小化偏差，该技术降低了并发症的风险，有助于实现更可预测和成功的牙齿修复。
