The norms of the "R" value may not be extended for other regional populations because they are based on the South Indian population group. Therefore, the goal of the current study is to determine the mean value and standard deviation for R angle in a population of North Indian suburbs for subjects with horizontal, average, and vertical growth patterns, as well as to assess its correlation with other variables used to gauge vertical discrepancy. The current cross-sectional study was carried out at the Swami Devi Dyal Dental College and Hospital, Barwala, Distt. Panchkula (Haryana), Department of Orthodontics and Dentofacial Orthopaedics, among 90 participants between the ages of 18 and 26 years having their pretreatment records. The parameters used in the study are R angle, Frankfort Mandibular Angle, Y- axis (Down’s Analysis), Facial axis, SOP, SNO, SNPP, MMA. The ratios analyzed in the study are Jarabak Ratio, Facial index, LAFH ratio, skeletal, LAFH, Soft tissue. The results of the study showed that high correlation was found between R angle and LAFH (Skeletal), Y Axis, Facial Axis, FMA, SNMP, Sum of posterior triangles (SOP), Maxillomandibular plane angle (MMA), SN to palatal plane angle (SNPP). A strong negative correlation was found between R angle and Jarabak ratio and facial index. There are many cephalometric parameters accessible, however not all of them point towards a certain pattern. In an effort to get around the difficulty of correctly and quickly identifying landmarks, the "R" angle was added.
“R”值的标准可能不会扩展到其他区域人口,因为它们是基于南印度人口群体的。因此,当前研究的目标是确定印度北部郊区人口中R角的平均值和标准差,以水平、平均和垂直增长模式为研究对象,并评估其与用于衡量垂直差异的其他变量的相关性。目前的横断面研究是在Barwala区Swami Devi Dyal牙科学院和医院进行的。Panchkula(哈里亚纳邦),正畸和牙面矫形科,年龄在18至26岁之间,有预处理记录的90名参与者。研究中使用的参数有R角、法兰克福下颌角、Y轴(唐氏分析)、面部轴、SOP、SNO、SNPP、MMA。研究中分析的比率为贾拉巴克比率、面部指数、LAFH比率、骨骼、LAFH、软组织。结果表明,R角与LAFH (skeleton)、Y轴、Facial轴、FMA、SNMP、后三角和(Sum of posterior triangle, SOP)、上颌骨平面角(Maxillomandibular plane angle, MMA)、SN -腭平面角(SN - pal腭平面角,SNPP)高度相关。R角与Jarabak比值、面部指数呈显著负相关。有许多可获得的头颅测量参数,但并非所有参数都指向特定的模式。为了解决正确和快速识别地标的困难,添加了“R”角。

IPS Emax is a lithium disilicate glass ceramic that has excellent translucency, longetivity, durability and strength for all restorations. It is a unique system that fulfills all of your patient demands for minimally invasive dentistry. It is a choice for single anterior/posterior crowns, as it truly mimics the light refraction and natural translucency necessary for outstanding esthetic appearance. Maxillary midline diastema with associated rotation of maxillary incisors presents a very challenging situation for dentist to meet the esthetic requirements. The presence of highly attached labial frenum in such patients adds to the complexity of the outcome of the treatment. Labial frenectomy done with the Laser presents a very quick and early satisfactory healing with no postoperative patient discomfort. Presenting a one such case report of rehabilitation of maxillary midline diastema with the IPS Emax ceramic laminate veneers.

The aim of this in vitro study is to compare three different techniques of scanning post space at different depths. The important factor for success of treatment depends on endodontic treatment as well as by restoring it with prosthodontic treatment. The post is mainly used to retain and hold the core so that crown prosthesis can be given. Fifteen freshly extracted single rooted teeth were selected and endodontically treated. Post space were created. Total Sample size taken was fifteen. There were three groups each with sample size of five. First group consist of Post space scanned with Omnicam intra oral scanner. Second group consist of Post space pattern scanned with InEos X5 Extraoral scanner. Third group consist of Post space impression made with Addition silicone, Poured and scanned with InEos X5 Extraoral scanner. Scanning files of all the three techniques were then converted to standard STL files. Diameter was measured at three different depths i.e., 3mm, 6mm & 9mm. Also, height & diameter was measured by 2 examiners to reduce bias. : The intra oral scanner showed the best accuracy of diameter and as the depth increases the accuracy decreases. Intraoral scanners showed the better accuracy and precision for scanning the post space as compared to extra oral scanner.
本体外研究的目的是比较三种不同的扫描后空间技术在不同深度。治疗成功的重要因素取决于根管治疗以及通过修复治疗恢复它。桩主要用于固定和托住牙核,以便给予冠假体。选择15颗刚拔除的单根牙进行根管治疗。创建了邮政空间。总样本量为15。共有三组,每组5个样本量。第一组由Omnicam口腔内扫描仪扫描的后腔空间组成。第二组由InEos X5口外扫描仪扫描的后空间模式组成。第三组由添加硅胶制成的后腔印模组成,用InEos X5口外扫描仪浇注和扫描。然后将所有三种技术的扫描文件转换为标准STL文件。直径测量在三个不同的深度,即3mm, 6mm &9毫米。还有,height &直径由2名检查员测量,以减少偏差。口腔内扫描的直径精度最高,随着深度的增加,精度降低。与口外扫描相比,口内扫描显示出更好的准确性和精密度。

Peripheral cementifying fibroma is a relatively uncommon, solitary, nonneoplastic gingival growth. They are usually painless and are often ignored by the patient until they become symptomatic or are diagnosed by the dentist. Due to long-standing, undiagnosed lesions, ulcerations were common. A recurrence rate of 5 – 20% was seen after excision. It depends on the diagnosis, the efficacy of the surgical removal, and the reduction of local irritating factors associated with their aetiology. Histologic diagnoses for the lesions are recommended clinically; they may be similar to various lesions, but the recurrence rates may differ. This report discusses a peripheral certifying fibroma affecting the mandibular posterior region; the lesion was excised surgically, followed by appropriate treatment.
周围骨水泥纤维瘤是一种相对罕见的、孤立的、非肿瘤性的牙龈生长。它们通常是无痛的,通常被患者忽视,直到它们出现症状或被牙医诊断出来。由于长期未确诊的病变,溃疡是常见的。术后复发率为5 - 20%。这取决于诊断,手术切除的效果,以及与病因相关的局部刺激因素的减少。临床建议对病变进行组织学诊断;它们可能与各种病变相似,但复发率可能不同。本报告讨论影响下颌后区外周证实纤维瘤;手术切除病变,然后进行适当的治疗。

The prosthodontic care for palatal defects is crucial for effectively closing oronasal communication in patients and enhancing various aspects of their oral health. This includes improving masticatory function, speech clarity, aesthetics, and overall comfort. Maxillary defects often arise as a result of surgical interventions for conditions like malformations, neoplasms, or traumatic injuries. In such cases, the primary objective of employing an obturator is to close the palatal defects that result from maxillectomy procedures, with the ultimate aim of enhancing both speech and masticatory function. This article presents a comprehensive case study highlighting the prosthetic rehabilitation of a maxillectomy defect resulting from osteosarcoma. The rehabilitation approach incorporates the use of a hollow bulb obturator, showcasing its transformative impact on the patient's masticatory function, speech clarity and aesthetics thus enhances the patient's quality of life.
腭部缺损的修复护理对于有效关闭患者的口鼻交流,提高患者口腔各方面健康水平至关重要。这包括改善咀嚼功能、语言清晰度、美观性和整体舒适度。上颌缺损通常是由于畸形、肿瘤或创伤性损伤等手术干预的结果。在这种情况下,使用闭孔器的主要目的是关闭上颌切除手术导致的腭缺陷,最终目的是增强语言和咀嚼功能。这篇文章提出了一个全面的案例研究,强调了由骨肉瘤引起的上颌切除缺陷的假肢康复。康复方法包括使用空心球闭孔,展示其对患者咀嚼功能,语言清晰度和美学的变革性影响,从而提高患者的生活质量。

Amelogenesis imperfecta refers to a group of rare, inherited disorders characterized by abnormal enamel formation. Patients mainly seek solution for unesthetic appearance caused by the condition. As prosthetic rehabilitation is essential for esthetics and function an interdisciplinary approach is often needed for restoration of health and its long-term maintenance. A multidisciplinary approach was mandatory for the management of this case. Short clinical crowns were present in all quadrant which made it difficult to achieve adequate retention and resistance forms for tooth replacement. In all quadrants, surgical crown lengthening was done by full thickness flap utilising a sub marginal incision with bone reduction wherever required to achieve bone level at least 3-4mm from gingival margin to facilitate supra crestal attachment (biologic width). After sufficient healing and stabilisation of gingival margins, prosthetic rehabilitation followed using fixed metal ceramic crown from molar to molar in both jaws. Depigmentation of the gingivae via conventional scalpel (upper arch) and laser (lower arch) was done to enhance the pink aesthetics. Sufficient crown length for a good resistance and retention form and adequate biologic width was established and pink white esthetic harmony was achieved.
釉质发育不全症是指一组罕见的遗传性疾病,其特征是釉质形成异常。患者主要寻求解决方案的不美观的外观造成的条件。由于假肢康复对美学和功能至关重要,因此经常需要跨学科的方法来恢复健康及其长期维持。多学科的方法是强制性的管理这一情况。临床冠短存在于所有象限,这使得难以获得足够的固位和阻力形式进行牙齿置换。在所有象限中,手术冠延长是通过全层皮瓣进行的,利用亚边缘切口,在需要的地方进行骨复位,以达到距牙龈边缘至少3-4mm的骨水平,以促进冠上附着(生物宽度)。在牙龈边缘充分愈合和稳定后,在双颌磨牙间使用固定金属陶瓷冠进行修复。通过常规手术刀(上弓)和激光(下弓)对牙龈进行脱色,以增强粉红色美学。建立了足够的冠长,以获得良好的抗性和固位形式,并建立了足够的生物宽度,实现了粉白美学的和谐。

In the majority of the cases with typical supernumerary tooth, mesiodens are the most widespread finding and may give rise to a variety of clinical symptoms, including displacement and obstruction, in the emergence and alignment of the adjoining teeth. The best time to remove the mesiodens is still up for debate, but it is typically suggested if there are any clinical complications or aesthetic issues present. While some authors advise awaited intervention following the full root development of the nearby teeth, others advise a rapid approach. In the present case report, one such patient's esthetics and quality of life have been successfully improved.
在大多数典型的多生牙病例中,中齿是最普遍的发现,并可能引起各种临床症状,包括相邻牙齿的出现和排列中的移位和阻塞。拔除中碘片的最佳时间仍有争议,但如果有任何临床并发症或美学问题,通常建议拔除。虽然一些作者建议在附近牙齿的牙根发育完全后再进行干预,但另一些人建议采取快速的方法。在本病例报告中,一个这样的病人的美学和生活质量已经成功地改善。

Intrusive injuries are common in primary dentition, however, only a limited number of cases have been reported involving permanent teeth. The present report describes a case of severe intrusion involving a maxillary central incisor wherein the tooth was displaced beyond the apical level of the adjacent teeth, into the nasal cavity. Without adequate clinical and radiographic examination, such cases tend to be misdiagnosed as avulsion and may present with numerous complications at a later stage. The present case report highlights the importance of a meticulous clinical examination, thorough radiographic evaluation, and appropriate surgical technique for the diagnosis and management of severely intruded permanent anterior teeth.
侵入性损伤在初级牙列中很常见,然而,只有有限数量的病例被报道涉及恒牙。本报告描述了一例严重的侵入涉及上颌中切牙,其中牙齿移位超过相邻牙齿的根尖水平,进入鼻腔。如果没有充分的临床和影像学检查,这些病例往往被误诊为撕脱,并可能在后期出现许多并发症。本病例报告强调了细致的临床检查,彻底的放射学评估和适当的手术技术对严重侵入的恒前牙的诊断和治疗的重要性。
