Achieving Osseo integration is of utmost importance for the success of implant therapy. Poor bone density (D3 & D4 type from Misch classification) is common in the maxillary jaw, especially in elderly patients which can create a hindrance to proper Osseo integration. A successful implant therapy would optimally re-create the lost mucogingival contours while maintaining their relationship to the prosthesis by replacing the tooth/ teeth. The time of implant placement plays a crucial role and is to be decided on a case-to-case basis. The present report describes a case of Osstem TS IV implant placement in the maxillary right premolar region with a delayed loading approach
实现骨整合对于植入治疗的成功至关重要。低骨密度(来自Misch分类的D3和D4型)在上颌很常见,特别是在老年患者中,这可能会阻碍正常的骨整合。一个成功的种植体治疗可以通过替换牙齿来重建失去的粘膜牙龈轮廓,同时保持它们与假体的关系。种植体放置的时间起着至关重要的作用,应根据具体情况决定。本报告描述了一例Osstem TS IV种植体放置在上颌右前磨牙区延迟加载入路

One of the surgical methods created to speed up orthodontic therapy is the periodontally accelerated osteogenic orthodontic (PAOO) tooth movement process. Numerous studies have documented a significant acceleration of orthodontic tooth movement after a combination of PAOO and bone grafting surgery, with the latter which helps in expansion of tooth movement and sustained improvement of the periodontium. The technique and surgical principles of PAOO for accelerating orthodontic tooth movement are highlighted in the following case reports

Dental caries is a public health issue that affects people all over the world. Untreated caries causes progressive tooth destruction, which is frequently accompanied by considerable pain, lowering one's quality of life. Fluoride use so as to reduce the causation of dental caries has been widespread since a long time which involves nearly six to eight decades. Especially in those people who have got the specific type of caries which involve their smooth surfaces only, can have topical fluorides applied at their site, not only smooth surface but also those cases which involves a tremendously increased amount of caries can also have their remedy in the form of application of topical fluorides. In this review we’ll analyze the usage and variety of cases in which we can apply topical fluorides in a community and how this practice can help in treating several caries at a widespread level and thus this is how it helps in reduction not only at an individual but also at a community level.
龋齿是一个影响全世界人民的公共卫生问题。如果龋齿得不到治疗,会导致牙齿逐渐受损,并常常伴有疼痛,从而降低生活质量。长期以来,人们普遍使用氟化物来减少龋齿的发生,大约有60至80年的历史。特别是那些有特定类型的龋齿的人只涉及到光滑的表面,可以在他们的部位局部使用氟化物,不仅是光滑的表面而且那些涉及到大量龋齿的病例也可以通过局部氟化物的应用来进行治疗。在这篇综述中,我们将分析在社区中应用局部氟化物的用法和各种情况,以及这种做法如何在广泛的水平上帮助治疗几种龋齿,从而不仅在个人层面上而且在社区层面上帮助减少龋齿。

The objective of the Study: Evaluation of the soft-tissue profile around the implant in the aesthetic zone of the anterior maxilla utilizing the PES after immediate implant placement with immediate provisionalization versus CAD/CAM provisionalizantion. Methodology: A total of 22 patients were randomly selected from the dental implant clinic. Eleven patients for the study group received CAD/CAM immediate temporization and eleven patients for the control group received chairside immediate temporization in the maxillary aesthetic zone. Results: In each group, there was a statistically significant increase in PES by time (P-value = 0.001). The mean pink aesthetic score of the control group was 9.57(±1.22) immediately and increased to 11.71(±1.13), while the mean PES for the study group was 9.79(±1.19) immediately and increased 12.60(±1.86) f after 4 months. Between the two groups, there was no statistically significant difference in the mean PES. We recorded overall favorable peri-implant soft tissue conditions. The study group showed a higher mean ISQ value than the control group after 4 months (P = 0.019). Conclusions: Although the CAD/CAM immediate provisionalization technique showed better esthetic results in immediate implant placement in the esthetic zone, no statistically significant difference between mean PES in the two groups. The immediate provisionalization technique in the two groups represents a valuable treatment choice for the restoration of the immediate implant in the anterior maxilla.
本研究的目的:利用PES评估即刻种植体置入即刻固定与CAD/CAM固定后上颌前美观区种植体周围的软组织轮廓。方法:随机选择种植牙门诊患者22例。研究组11例患者采用CAD/CAM即刻颞动术,对照组11例患者采用上颌美观区椅侧即刻颞动术。结果:各组患者PES随时间升高均有统计学意义(p值= 0.001)。对照组即刻粉红美学评分平均为9.57(±1.22)分,4个月后上升至11.71(±1.13)分;研究组即刻粉红美学评分平均为9.79(±1.19)分,4个月后上升12.60(±1.86)分。两组间PES平均值比较,差异无统计学意义。我们记录了总体良好的种植体周围软组织状况。4个月后,研究组的平均ISQ值高于对照组(P = 0.019)。结论:虽然CAD/CAM即刻预备技术在美观区即刻植入具有更好的美观效果,但两组平均PES无统计学差异。两组即刻预备技术是上颌前牙即刻种植体修复的一种有价值的治疗选择。

Introduction: Knowledge of root canal anatomy is essential in order to achieve a successful root canal treatment. C shaped canal anatomy is most commonly seen in mandibular second molars and to some extent mandibular premolars. Such canals are difficult to negotiate, debride/disinfect and obturate due to its high incidence of fins, webs, lateral canals and anastomoses. Inability to identify and debride such canal anatomy may lead to endodontic failure. Case Report: These case series highlights on two different c shaped canals with two different obturation techniques. Conclusion: Complexity of C shaped canal morphology can be managed successfully with proper irrigation and obturation techniques.
简介:根管解剖学的知识是必不可少的,以实现根管治疗的成功。C形管解剖最常见于下颌第二磨牙和下颌前磨牙。由于翅片、蹼片、外侧管和吻合口发生率高,这些管难以通畅、清创/消毒和封闭。不能识别和清除这种根管解剖可能导致根管失败。病例报告:这些病例系列强调了两种不同的c形管和两种不同的封闭技术。结论:采用适当的冲洗和封闭技术,可以成功地控制C形管形态的复杂性。

The effect of different air blasting pressure of polyetheretherketone (PEEK) on surface roughness and bond strength to adhesive resin cement: An in-vitro study 不同空气爆破压力对聚醚醚酮(PEEK)表面粗糙度和与胶结树脂水泥结合强度的影响:体外研究

Statement of the Problem: Polyetheretherketone material shows good physical and mechanical properties but research is lacking optimum air blasting parameters for good bond strength to resin cement. Aim: To evaluate the effect of different air blasting pressure of PEEK on surface roughness and shear bond strength to adhesive resin cement. Materials and Methods: 24 discs of BioHPP PEEK (bredent, UK) were manufactured. Samples were air blasted with 110 μm Al 2 O 3 particles for 10 seconds at distance of 10 mm and divided into 3 groups according to pressure. Group A: 3 bar, Group B: 2.5 bar and Group C: 3.5 bar. Surface roughness was measured by SEM, Visio Link primer (Bredent, Germany) was applied and cured then G-CEM resin cement (GC, Japan) was applied and cured. Shear bond strength was measured using universal testing machine. EDX analysis was done, and failure mode was detected by stereo-microscope. Results: Statistical analysis showed that roughness average (Ra) increased by increasing pressure, Group B was significantly the lowest ( p < 0.05), while there was insignificant difference between other groups (P > 0.05). Regarding shear bond strength, Group A recorded (12.6864 ± 2.486 MPa), Group B (11.2842 ± 1.555 MPa) and Group C (10.1024 ± 2.317 MPa), there was significantly statistical difference between Groups A & C ( p < 0.05). The failure mode was mainly adhesive in group C and mixed in groups A & B. EDX analysis showed an increase in Carbon and Silica and a decrease in Oxygen and Aluminum weight percentages after the bond strength test. Conclusion: Increasing the air blasting pressure up to 3 bar increases the surface roughness and bond strength to resin cement, but more than 3 bar showed unfavorable surface roughness and decreased bond strength.
问题陈述:聚醚醚酮材料具有良好的物理力学性能,但缺乏与树脂水泥良好粘结强度的最佳空气爆破参数研究。目的:评价不同空气爆破压力对聚醚醚酮(PEEK)表面粗糙度和与树脂水泥的剪切结合强度的影响。材料和方法:制备了24片BioHPP PEEK (bredent, UK)。用110 μm Al 2o3颗粒在10 mm距离处空气爆破10秒,按压力大小分为3组。A组:3bar, B组:2.5 bar, C组:3.5 bar。表面粗糙度通过扫描电镜测量,涂上Visio Link底漆(Bredent, Germany)并固化,然后涂上G-CEM树脂水泥(GC, Japan)并固化。剪切强度采用万能试验机进行测定。进行了EDX分析,并用立体显微镜检测了失效模式。结果:统计学分析显示,粗糙度平均值(Ra)随压力的增加而升高,其中B组最低(p < 0.05),其他组间差异不显著(p > 0.05)。剪切结合强度A组(12.6864±2.486 MPa)、B组(11.2842±1.555 MPa)、C组(10.1024±2.317 MPa), A、C组间差异有统计学意义(p < 0.05)。C组以粘结破坏为主,A组和b组混合破坏。EDX分析表明,粘结强度试验后,碳和硅的重量百分比增加,氧和铝的重量百分比减少。结论:空气爆破压力增加到3bar时,表面粗糙度和树脂水泥的结合强度都有所增加,但超过3bar时,表面粗糙度变差,结合强度下降。

Antiseptic agents are used as an adjunctive tool in periodontal therapy, to prevent infection, better plaque removal, as well as preoperative cleaning of the surgical site, and postoperative use. Chlorhexidine is considered a good antiseptic agent, but it has several important adverse health effects if not used correctly by the patient. The objectives of this review are: a) To understand the different antiseptics that exist, b) To determine the adverse effects of chlorhexidine, c) To compare the effects of antiseptics in different studies.
