“…Postoperative imaging to confirm the water jet holes, using computed tomography scans for example, could have provided an objective assessment, but were deemed an unnecessary burden for the animals since extensive imaging in ex vivo studies has shown the ability of water jet to machine bone when the technique is used correc tly. 8,25,26,38,48 The next steps in the development of the water jet drilling technique will be the design of a medical pump that offers stable high pressures and a flexible arthroscopic water jet drill that is suitable for performing microfracture during an arthroscopic procedure (Fig. 1).…”

“…We based this on our previous research, where we water jet drilled in bones with varying mineral densities using numerous machine settings, and determined the drilling depth with micro–computed tomographic analyses. 25 , 26 , 38 An even distribution was achieved by turning the nozzle head in plane with an off-center turning wheel following each burst. The saline pressure was monitored using the integrated pressure gauge at the pump.…”

Objective Surgical microfracture is considered a first-line treatment for talar osteochondral defects. However, current rigid awls and drills limit access to all locations in human joints and increase risk of heat necrosis of bone. Using a flexible water jet instrument to drill holes can improve the reachability of the defect without inducing thermal damage. The aim of this feasibility study is to determine whether water jet drilling is potentially safe compared with conventional microfracture awls by studying side effects and perioperative complications, as well as the quality of cartilage repair tissue. Design Talar chondral defects with 6-mm diameter were created bilaterally in 6 goats (12 samples). One defect in each goat was treated with microfracture created with conventional awls, the contralateral defect was treated with holes created with 5-second water jet bursts at a pressure of 50 MPa. Postoperative complications were recorded and after 24 weeks analyses were performed using the ICRS (International Cartilage Repair Society) macroscopic score and modified O’Driscoll histological score. Results Several practical issues using the water jet in the operating theatre were noted. Water jet drilling resulted in fibrocartilage repair tissue similar to the repair tissue from conventional awls. Conclusions These results suggest that water jet drilling gives adequate fibrocartilage repair tissue. Furthermore, the results highlight essential prerequisites for safe application of surgical water jet drilling: stable water pressure, water jet beam coherence, stable positioning of the nozzle head when jetting, and minimizing excessive fluid extravasation.

Although continuous progress in technical advancement, the conventional machining process has became unsatisfactory in healthcare due to its disadvantages. This inadequacy has led researches to consider using the application of nontraditional machining that can machine extremely hard and brittle materials into complicated shapes in healthcare. Researches have proved that diverse NTM applications of Water Jet Machining (WJM), Ultrasonic Machining

Water jet as a novel technique for enamel drilling ex vivo

et al. 2021

To investigate the usage of a water jet for enamel drilling ex vivo, 210 individual extracted molars without lesions or fillings were collected. Then, the specimens were drilled by a water jet or a high-speed dental drill. The cavities of 50 teeth were reconstructed digitally by micro-computed tomography (micro-CT) to measure the height and width. The cavities of 10 teeth were longitudinally incised and their surfaces were observed by scanning electronic microscopy (SEM). After the cavities were filled, 50 fillings were vertically incised. The bonding interface between tooth and filling was observed by SEM. 50 teeth with fillings were stained in 0.1% rhodamine B solution, and then the dye penetration between tooth and filling was observed under the stereomicroscope and confocal laser scanning microscopy (CLSM). The bonding strength between enamel and filling of 50 teeth was simulated and predicted with finite element analysis (FEA). At 140–150 MPa and for 2–3 s, cavities were made with a depth of approximately 764 μm in each tooth. SEM showed the cavity surface in the water jet group had a more irregular concave and convex structure than that in the high-speed dental drill group. There was a trend that the microleakage and bonding width was smaller in the water jet group than in the high-speed dental drill group. FEA indicated that the stress on the resin surface was greater than on the enamel surface in the water jet group. Compared with the tooth drilled by a high-speed dental drill, the tooth drilled by a water jet gained better retention of the filling material and suffered less bonding strength on the enamel surface. Water jet drilling is effective for enamel drilling.
