“…Conventionally, orthodontic model analysis entails constructing plaster models of the upper and lower teeth and manually taking measurements [9]. Dental models are essential in fabricating the crown prosthesis, where crown refers to the part that covers the top of the tooth, preoperative preparations for implantation, and orthodontic model analysis [10,11,26]. Plaster models are integral to orthodontic patient profiles and are widely used throughout treatment.…”

Accurate analysis of dental models is crucial for diagnosing and treating malocclusion successfully. Traditional measurement techniques, however, often fail to accurately measure teeth in crowded conditions. In this study, we introduce Fusion Analyser, an innovative software tool capable of calculating key dental indicators, thereby advancing the scope of digital dental model analysis. Our unique Fusion Analyser framework employs segmentation discs on teeth to enhance the accuracy of the anterior Bolton's ratio, outperforming the widely-used 3Shape software when dealing with crowded teeth. The Fusion Analyser framework exhibits performance commensurate with the established gold standard, as evidenced by high scores across a range of evaluation metrics, thereby validating its accuracy, stability, and efficiency. The potential of the Fusion Analyser framework as an auxiliary tool for dentists, particularly in diagnosing and strategizing treatment plans for malocclusion, is underscored.

“…It has been demonstrated that surface textures are an effective method for reducing bacterial behavior at interfaces [28][29][30]. Several successful attempts have been made to study the antibacterial behavior of dental materials using laser surface texturing methods [14,31,32].

The continuous need for high-performance implants that provide significant biological properties has led to extensive research into the topographic patterns of bioceramics in recent years. Their excellent aesthetics, biocompatibility, low plaque affinity, and ability to reproduce a natural-looking appearance have contributed to their success in dentistry. 3 mol% Yttria-stabilized zirconia (3YSZ) is gaining popularity as a material for dental implants due to its excellent mechanical properties and minimal degradation when exposed to body temperature. However, such materials show limited biological and antibacterial performance for dental applications. The purpose of this work was to develop microtopographies on the surface of 3YSZ ceramic by laser ablation technique, in order to improve its biological response and antibacterial behaviors. Two types of microtextures, including micro-grooves and micro-channels geometries were fabricated onto the zirconia ceramics using the laser ablation technique. The effects of different microtextures on the wettability, biological and antibacterial behaviors of 3YSZ ceramics were studied. The results indicate that all of the microstructure patterns are capable of improving the performance of 3YSZ. Wettability is a decisive factor that determines the antibacterial performance of textured zirconia ceramics. The microtextured surfaces all display hydrophobic behavior, thus yielding an effective improvement of antibacterial performance for 3YSZ ceramics. Cell-surface interactions were assessed for 7 days on both zirconia textured surfaces and a nontextured control with pre-osteoblast MC3T3-E1 cells. The obtained results showed the positive influence of textured zirconia surfaces on cell biological response.

“…From the perspective of wettability modification of the background surface and preparation of the SHPi grooves, laser processing is a feasible and effective surface technology [22]. It has been successfully applied to various materials for different applications, such as titanium [23], silicone rubber [24,25], and zirconia ceramics [26]. In particular, rapid antigravity transport of water could be realized in the parallel Vshaped microgroove arrays prepared with a femtosecond laser [27].…”

Ultra-thin heat pipes have been widely used for thermal management of electronic components. The capillary performance of the wicking structure is an essential factor that affects its heat transfer capability. In this study, superhydrophilic and superhydrophobic background surfaces were prepared on aluminum sheets using a nanosecond fiber laser. Superhydrophilic grooves with a width of 0.1-0.4 mm were fabricated on surfaces with different wettability by laser processing. The effects of the background wettability on the capillary performance of the grooves were investigated. When the groove widths were 0.1-0.2 mm, the water in the groove rose the fastest on the superhydrophobic background surface. As the groove width increased to 0.3-0.4 mm, the water in the groove on the superhydrophilic surface rose the most rapidly. Furthermore, the water absorption of grooves with the same width on the superhydrophilic background surface was always greater than that of the grooves on the other two surfaces. Therefore, a matching wettable background surface should be selected according to application requirements. A superhydrophobic background surface can be chosen when a faster rise in the speed of the water in the groove is preferred. In contrast, a superhydrophilic background surface is beneficial for improving the water absorption capacity. The water absorption of the groove on the superhydrophilic background surface reaches a maximum of 6.8 mg with a groove width of 0.4 mm, and the capillary performance parameters can reach 4.26e-7 N, which is 100.9 % enhanced over the pristine background surface. Thus, this study provides new ideas for improving the capillary performance of vertically grooved wicks.
