The clinical significance of keratinized gingiva around dental implants

Whether or not keratinized tissue is needed around dental implants to maintain peri-implant health is a controversial subject. To clarify this issue a search was conducted for clinical trials that appraised the significance ofkeratinized gingiva (KG) around teeth and dental implants. A critical assessment of the data revealed that the literature is replete with studies that contradict one another with respect to the need for KG as it relates to survivability of implants, gingival response to plaque, inflammation, probing depths, recession, and loss of bone. When groups of patients with and without KG were compared with respect to various clinical parameters, a statistically significant better result in the presence of KG could be interpreted to indicate that having KG is advantageous. However, quantitative differences between groups with and without KG were usually very small. Overall, the data was interpreted to indicate that some patients may need augmentation of keratinized tissue to maintain peri-implant health. Ultimately, the decision to augment KG is a judgment call that needs to be made by the treating clinician, because there are not enough data to facilitate development of definitive guidelines relevant to this subject. Apparently, the need for KG is patient specific, and at present there is no method to reliably predict who would benefit from tissue augmentation.     

Rationale for dental implants

The clinical replacement of lost natural teeth by osseointegrated implants has represented one of the most significant advances in restorative dentistry. Two decades ago, a majority of dentists were sceptical about implants and rejected them entirely. Today it is rare to find a practitioner who does not work with dental implants or who is not actively participating in one of the many seminars or courses offered by universities, professional societies and implant manufacturers.     

The importance of dental implants

Implant dentistry has evolved into the mainstream of restorative practices all over the world. Maintenance of bone after tooth loss to improve or maintain facial esthetics and improved retention, function, and performance of removable restorations are only some of the advantages for the edentulous patient. No longer are implants considered only when traditional restorations cannot be fabricated. Evidence-based reports indicate implant restorations last longer than those on teeth and the abutment teeth are at less risk of loss or complication.     

应用于牙种植力学分析的下颌骨材料赋值问题研究

目的：本文考察牙种植有限元分析中下颌骨模型材料赋值分别采用模拟患者骨质精确化赋值和均匀赋值后的生物力学情况和特点。方法：采用螺旋CT扫描,mimics软件逆向建立下颌骨三维模型和推导精确化赋材料参数公式,在有限元软件中装配有限元模型并模拟咬合力加载,分析种植体对于下颌骨应力分布情况。结果：两种不同处理情况下的下颌骨应力分布有较大不同点,真实病例牙列缺损部分赋值材料应力值明显低于均匀赋值材料的属性。结论：相对均匀赋值法,采取精确化赋值应力大致反映患者真实的应力情况,对于口腔医师针对具体病例术前研究和术后评价具有更高的借鉴性。

The immediate loading of dental implants

The aim of this article is to identify current opportunities for the immediate loading of endosseous dental implants. A biologic basis for the clinical parameters associated with success and failure of immediately loaded implants is presented, and select clinical situations where immediate loading is presently advocated will be illustrated. The wide-ranging applications of the immediate-loading concept for endosseous dental implants will be introduced; however, further experimental validation is necessary before incorporating all of these various expedited therapeutic approaches into practice.
