Welcome to the lecture on dynamic navigation in implant dentistry. In this series, we will discuss about the use of dynamic navigation in implant dentistry in daily practice. First of all, why accurate implant placement is important in practicing implant therapy? Accurate position of the dental implant is required to achieve best functional and aesthetic result. Furthermore, to avoid the risk for biomechanical overload. The accuracy of the implant position can be achieved with the use of a static surgical guide. There are some some new tools and techniques available in implant dentistry that were developed to facilitate our procedures. New tools are available to assist the digital implant planning and aid in implant placement. There are a few techniques to facilitate this transfer: Computer guided implant surgery, computer navigated (dynamic) implant surgery, and last, robotic implant dentistry. This slide shows a static surgical guide. After the digital implant planning is complete, the information from the software is transferred to the laboratory technician. The radiographic guide can then be converted into a surgical guide by placing the appropriate surgical guide sleeves to facilitate proper implant placement. The surgeon, later on, will utilize the surgical guide at the time of the surgery to place the dental implant in the 3-dimensional ideal position. There are some limitations that we should be aware of regarding the static surgical guide. Although the static surgical guide is a great tool that can help us in the positioning accurately the implant during the surgery, there are some limitations that need to be considered. Limited posterior clearance, drill site visibility, access for proper irrigation, fit and retention of the stent, especially after the flap elevation, additional cost, and the time required to fabricate it. Dynamic surgical guide. The dynamic navigation system is a technology designed to guide the placement of dental implants in real time by a computer, and based on information generated from the patient's computed tomography. These systems are empowered by a motion-tracking technology, which tracks the position of the dental drill and the position of the patient throughout the implant placement procedure. Inliant Clinical Component is one of the systems. It's a dynamic surgical guidance system, and it's composed of four different parts. A handpiece with markers that directly laser-engraved on the handpiece. No attachment on the handpiece. Patient tracker with Inliant markers, that is attached to patient during surgery. Two Inliant cameras attached directly to your existing dental light. And also, an intuitive software with integrative surgical protocol and planning. There is some advantages that we might want to consider. Surgical guides direct the bone entry point and angulations of the drill, but they neither reference the underlying anatomical structures nor provide exact 3-dimensional guidance. The navigation system, on the other hand, allows the surgeon to guide instrument freely, as in conventional treatment. It allows intra-operative changes for the implant position. The virtual surgical plan can be altered or modified during surgery, and the clinician can use the navigation system to concurrently visualize the patient's anatomy. These benefits directly impact patient's chair-time during surgery. Patient will spend less chair-time, decreasing the amount of physical strain on the patient and able to leave the surgery with a better overall experience. On the other hand, the decreased chair-time allows the surgeon to increase the number of cases performed per day. One may believe that increasing the number of surgeries performed in one day may actually increase the physical strain on the surgeon, but the dynamic navigation system improves the surgeon's ergonomics. It can decrease the physical strain on the surgeon, especially for the maxillary arch, as it is very difficult to maintain proper ergonomics and maintain visibility, and can increase the quality of life. There are certain disadvantages. For example, pre-surgical virtual surgery planning can be very time-consuming for the surgeon. One of the major challenges with this system is the need for additional space in the operatory. The high cost for the purchase, updates, and maintenance of the system, may not make it financially feasible to purchase the system. A lack of the communication between the sensors and the handpiece due to sensor error or sensors being blocked can also be expected during the procedure. Some future thoughts that we might want to emphasize. Advancements in dental technology can offer modern solutions to traditional dental problems. Through the technological advancements in digital implant dentistry, the workflow will be streamlined, and enhance the overall interdisciplinary collaboration. Computerized navigation implant surgery is a promising technology, although certain challenges, such as cost and accuracy will still remain to be addressed. The use of this technology in dentistry may substantially contribute to increase in to increasing the quality of treatment rendered, similar to the medical field. Adequate clinical skills are expected from the surgeon. Intra-operative application can be significantly longer than with the static method, partially due to setting up of the navigation device. That's all we want to discuss about the dynamic navigation in implant dentistry. Thank you for your attention.
