The effect of various drying methods on bonding strength is still controversial.</p> <p><strong>Objective:</strong> The aim of this study is to determine whether different drying methods and durations affect the bonding strength between leucite reinforced glass ceramics and resin cement.</p> <p><strong>Materials and Methods:</strong> Thirty different leucite reinforced glass ceramic (G-Ceram, Atlas Enta) specimens were divided into 5 groups. All specimens were treated with 5% hydrofluoric acid (HF) (IPS Ceramic Etching Gel, for 60 seconds according to the manufacturer's instructions. After acid etching, specimens were rinsed with water spray for the duration of acid etching and dried with pressurized air. Following the application of primer (Monobond N, Ivoclar Vivadent), specimens were divided into 5 groups based on air-drying methods and durations: Control (C) group (dried with pressurized air for 10 seconds; air drying in ceramic furnace for 30 seconds (CF30); air drying in ceramic furnace for 60 seconds (CF60); air drying with a hair dryer for 30 seconds (HD30); air drying with a hair dryer for 60 seconds (HD60). Ceramic specimens were bonded with dual cure resin cement (Multilink N; Ivoclar Vivadent) using a split Teflon mold with a diameter of 2.5 mm. Force was applied to the specimens with a 1 mm/min speed using a chisel-shaped applicator tip until failure occurred. The results were analyzed using one-way ANOVA followed by Tukey's post hoc test within the 95% confidence interval.</p> <p><strong>Results:</strong> There was a significant difference among the mean bond strength values of the groups (P&lt;0.05). Group CF60 and Group HD60 both exhibited significantly higher mean shear bond strength values compared with the group C (P&lt;0.05). Group CF30 and Group HD30 showed similar bonding values with CF60, HD60 and C groups (P&gt;0.05).</p> <p><strong>Conclusions:</strong> Drying the primer with ceramic furnace or the hair dryer for 60 seconds significantly enhanced the bonding strength between the leucite-reinforced glass ceramic and resin cement.</p> 2024-06-28T00:00:00+00:00 Copyright (c) 2024 Bilgehan Kottaş, Melika Ahmad, Semih Akdoğan, Abdulhaluk Savaş, Tuba Yılmaz Savaş https://asc.kapadokya.edu.tr/index.php/asc/article/view/46 Evaluation of Facial Depth in Maxillary-Based Class III Individuals: A Cephalometric Study" 2024-04-30T13:52:34+00:00 Fırat Koç firatkoc@hotmail.com Deniz Sağdıç dsagdic@hotmail.com Ragıp Burak Orsçelik rborscelik@hotmail.com <p><strong>Statement of problem:</strong> There is a lack of data in the literature regarding the relationship between the average facial depth distance and this distance with the anterior facial height in patients exhibiting skeletal class III malocclusion originating from the maxilla.</p> <p><strong>Objective:</strong> The aim of this study is to investigate the amount of average facial depth in maxillary-based Class III cases and to evaluate the relationship between average facial depth and anterior facial height.</p> <p><strong>Materials &amp; Methods:</strong> The study comprised 592 individuals diagnosed with Class III malocclusion, of whom 281 were female and 311 were male.

On cephalometric radiographs of the participants, the pogonion (Po), nasion (N), Frankfort Horizontal plane (FH), condylion (Co), and menton (Me) points were marked. The anterior facial height of the patients was calculated, and all participants were divided into three groups: long, average, and short. The distance where Co and N intersected the FH was defined as the 'facial depth distance' (Co-N). Finally, the ratio of the facial depth distance (Co-N) to the anterior facial height (N-Me) was calculated.</p> <p><strong>Results:</strong> A significant difference was observed in the mean ratio of Co'-N' to N-Me between long-faced individuals and short-faced individuals (P &lt; 0.05).

In the treatment of orthognathic surgery, it has been a long-standing approach to plan orthognathic surgery using traditional two-dimensional cephalometric planning and model surgery after fixed orthodontic treatment, which allows for the decompensation of malocclusion to improve skeletal correction and position of the teeth ideally. However, with advancing techniques, both the elimination of pre-surgical orthodontic treatment, which prolongs the treatment time and negatively affects the patient's psychology, through the Surgery First method, and the possibility of planning more accurate surgeries with three-dimensional virtual surgical planning have become widespread. In this case report, the treatment outcomes of two adult individuals with bimaxillary orthognathic surgery planned for skeletal Class III malocclusion using three-dimensional virtual surgical planning software will be presented, comparing the results achieved with both the traditional method and the Surgery First method.</p> <p>&nbsp;</p> <p><strong>Keywords: </strong>Orthognathic Surgery, Surgery First, Orthodontic Treatment, 3D Planning</p> 2024-06-28T00:00:00+00:00 Copyright (c) 2024 Ezgi Kurt, Merve Berika Kadıoğlu, Meliha Rübendiz
