Abstract
Objectives
This study investigates the impact of drill play on the precision of implant positioning under lateral forces in guided implantology.
Materials and Methods
An in vitro experiment was conducted using artificial bone blocks and the SIC Invent-guided surgery implant system. Custom drill guides were designed, and 3D-printed, using three sleeve types: sleeveless, a big sleeve, and a small sleeve. Drillings were performed with varying lateral forces, and deviations in angle, depth, and position were measured.
Results
Sleeveless guides showed the highest variability in deviations, with a maximum deviation of 3.92 mm under extreme lateral forces. Big sleeve guides provided the most consistent precision, with deviations ranging from 0.42 to 1.33 mm. Small sleeve guides showed moderate precision, with deviations from 0.14 to 2.17 mm. Higher lateral forces generally increased deviations across all guide types.
Conclusions
Drill play significantly affects the precision of guided implant drilling, with lateral forces causing deviations from the planned implant position. Big sleeve guides offer better precision under lateral loads compared to sleeveless and small sleeve guides. Strict adherence to the drilling protocol is essential to minimize errors and ensure optimal implant positioning.
期刊介绍:
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
