Análisis mediante un estudio in vitro de la precisión quirúrgica en las osteotomías realizadas usando el nuevo sistema universal de topes desechables para fresas implantológicas FCA Universal Drill Stop

Abstract

Background: To achieve implantological success, implants must be placed safely and efficiently, in this sense, it is advisable to use implantological drill stops that maximize precision during the intervention. Objective: To evaluate the surgical precision of a new universal system of disposable implant drill stops called FCA Universal Drill Stop. Material and Methods: We used a total of 60 bovine cow ribs in this in vitro study. Ribs were randomized into three study groups (n=20 ribs per group). In each of the study groups (Group 1: drills without stop or control group, Group 2: prefabricated drills with stops or gold standard group, and Group 3: drills with stops of the new FCA Universal Drill Stop system), we performed a total of 100 implant drills following the drilling sequence for the placement of a dental implant 10 mm long and 4 mm in diameter (2; 2.6; 3.2 and 3.6 mm diameter drills). The depth precision of the osteotomies was quantified clinically (with periodontal probe) and radiologically using ImageJ image analysis software version 1.48v. Results: The order from highest to lowest precision (clinical and radiological) in the depth of the osteotomies was: FCA Universal Drill Stop>prefabricated drills with stop (gold standard)>drills without stop (control); observing statistically significant differences between both drills stop systems with the control group, although not between them. Conclusions: The new universal system of disposable stops for implant drills FCA Universal Drill Stop offers a precision similar to prefabricated drills with stops, both systems being much more precise than surgical drills without stops.
