Graphpad prism 5 iso file4/17/2023 ![]() ![]() ![]() Complex requirements for optimal implant positioning make profound preoperative and surgical-prosthetic planning necessary. ![]() Current approaches are mostly based on a prosthetically driven treatment concept, the so-called backwards planning. Demands on functionality and esthetics have increased significantly overall. ![]() Today, the use of dental implants is an established procedure for rehabilitation of the masticatory apparatus after tooth loss. However, further clinical studies need to follow in order to provide an evidence-based recommendation for use in vivo. ConclusionĬonsidering the limitations of an in vitro study, dynamic navigation can be used be a tool for reliable and accurate implantation. Regarding angulation, it was found that the closer the drill hole was to the system's marker, the better navigation performed. When using the pilot drill guide, horizontal deviation was 0.34 mm in the median and at the tip by 0.59 mm. Median horizontal deviation was 0.52 mm at base and 0.75 mm at tip using DENACAM ®. Its inaccuracy was 3° the template-guided systems was 4.6°. With regard to angulation, real-time navigation was more precise ( p = 0.0016). Resultsīoth systems achieved clinically acceptable results, yet more accurate results regarding the offset of implant base and tip in several spatial dimensions were achieved using drilling guides (each p < 0.05). Accuracy was assessed by cone-beam computed tomography (CBCT). In addition, implant placement in interdental gaps and free-end situations were investigated. 30 were placed with pilot drilling guides, the other half with dynamic navigation (DENACAM ®). MethodsĪ total of 60 implants were placed on 12 partially edentulous lower jaw models. The aim of this study is to compare the accuracy of implant placement using a 3D-printed drilling guide and an intraoral real-time dynamic navigation system. Nowadays, 3D planning and static for dynamic aids play an increasing role in oral rehabilitation of the masticatory apparatus with dental implants. ![]()
