<p><strong>Statement of the problem:</strong> Studies are ongoing to enhance the bonding strength between glass ceramic restorations and resin cements. 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<0.05). Group CF60 and Group HD60 both exhibited significantly higher mean shear bond strength values compared with the group C (P<0.05). Group CF30 and Group HD30 showed similar bonding values with CF60, HD60 and C groups (P>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>Bilgehan KottaşMelika AhmadSemih AkdoğanAbdulhaluk SavaşTuba Yılmaz Savaş

https://asc.kapadokya.edu.tr/index.php/asc/article/view/46
<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 & Methods:</strong> The study comprised 592 individuals diagnosed with Class III malocclusion, of whom 281 were female and 311 were male. The pogonion (Po), nasion (N), Frankfort Horizontal plane (FH), condylion (Co), and menton (Me) points were marked on the cephalometric radiographs of the participants. The projection of point Co to point N on the FH plane (Co'-N') was defined as the facial depth distance, while the distance between N and Me was determined as the anterior facial height distance. Subsequently, the facial depth distances of all individuals were measured. The facial depth distance was then ratioed with the anterior facial height distance in an attempt to reach standard ratios for maxillary-based Class III cases.</p> <p><strong>Results:</strong> A The average facial depth distance (Coꞌ-Nꞌ) is 83 ± 7 mm. The ratio of facial depth distance (Coꞌ-Nꞌ) to anterior facial height (N-Me) (Coꞌ-Nꞌ/N-Me) is determined to be 68 ± 5%.-When this ratio is evaluated separately according to facial heights; it is determined as 66 ± 4% in long-faced individuals, 67 ± 4% in normal-faced individuals, and 71 ± 5% in short-faced individuals.</p> <p><strong>Conclusions: </strong>The use of this ratio in cephalometric film analysis may bring a new perspective to the evaluation of maxillary Class III malocclusions.</p>Fırat KoçDeniz SağdıçRagıp Burak Orsçelik

https://asc.kapadokya.edu.tr/index.php/asc/article/view/47
<p><strong>Statement of problem:</strong> The literature currently lacks sufficient data on the correlation between the average facial depth distance and its relationship with the anterior facial height in individuals presenting with skeletal Class II malocclusion of maxillary origin.</p> <p><strong>Objective:</strong> This study aims to examine the extent of average facial depth in individuals with maxillary-based Class II malocclusion and to assess the correlation between average facial depth and anterior facial height.</p> <p><strong>Materials & Methods:</strong> The study included 712 individuals with Class III malocclusion, with 361 being female and 351 male. Cephalometric radiographs of the participants were used to identify the pogonion (Po), nasion (N), Frankfort Horizontal plane (FH), condylion (Co), and menton (Me) points. The distance from point Co projected onto the FH plane to point N (Co'-N') was determined as the facial depth distance, while the distance between points N and Me was considered the anterior facial height distance. Subsequently, the facial depth distances of all individuals were measured and ratioed with the anterior facial height distance to establish standardized ratios for maxillary-based Class II cases.</p> <p><strong>Results:</strong> The mean facial depth measurement (Coꞌ-Nꞌ) is 86±5mm, with a corresponding ratio to the anterior facial height (N-Me) of 69±5%. When categorized by facial morphology, this ratio was determined to be 67±4% for individuals with longer faces, 68±4% for those with average facial lengths, and 70±5% for individuals with shorter facial lengths.</p> <p><strong>Conclusions: </strong>Utilizing the Coꞌ-Nꞌ/N-Me ratio in cephalometric analysis could provide a fresh perspective on evaluating skeletal Class II malocclusions arising from maxillary development.</p>Korhan GiderHüseyin ÖlmezRagıp Burak Örsçelik

https://asc.kapadokya.edu.tr/index.php/asc/article/view/44
<p><strong>Statement of problem:</strong> In patients with mandibular prognathism and skeletal Class III malocclusion, there is a lack of data regarding the relationship between average facial depth and anterior facial height.</p> <p><strong>Objective:</strong> The objective of this study is to determine the average facial depth in patients with mandibular-origin skeletal Class III malocclusion and to investigate the relationship between this measurement and anterior facial height.</p> <p><strong>Materials & Methods:</strong> A total of 626 individuals with Class III malocclusion were included in the study (292 females, 335 males). 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 < 0.05). The ratio of the facial depth distance (Co'-N') to the anterior facial height (N-Me) was found to be 69% ± 5. This ratio was determined to be 68% ± 4 in long-faced individuals, 69% ± 4 in average-faced individuals, and 72% ± 5 in short-faced individuals.</p> <p><strong>Conclusions: </strong>The ratio between Co-N and N-Me may provide a new perspective in the evaluation of mandibular-origin Class III malocclusions.</p>Ragıp Burak Orscelik

2024-06-282024-06-2841213210.54995/ASC.4.1.2Two Different Approaches In Three-Dimensional Planning Of Orthognathic Surgery: Surgery First And Traditional Orthognathic Surgery
https://asc.kapadokya.edu.tr/index.php/asc/article/view/43
<p>In individuals with completed growth development and Class III malocclusion, orthognathic surgery is inevitable for achieving ideal occlusion and facial aesthetics. 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> </p> <p><strong>Keywords: </strong>Orthognathic Surgery, Surgery First, Orthodontic Treatment, 3D Planning</p>Meliha RübendizMerve Berika KadıoğluEzgi Kurt
