[Dentures on osteointegrated implants: a new alternative in treatment of the edentulous patient]. [骨整合种植体义齿:治疗无牙患者的新选择]。
Stoma (Lisbon, Portugal)

The bone anchorage of an implant is a complex problem, not only dependent on the material used, but also on other variables like macro- and microstructure of the implant, surgical technique, time and mode of implant loading, and status of the host bone. Brånemark et al. have shown excellent clinical results in the rehabilitation of completely edentulous patients with prostheses on osseointegrated implants. The 15 year success rate of 90% or more is associated with an essential fact: the direct bone-titanium connection, without the intervention of any fibrous tissue. Contrary to the fibrous tissue interface, the osseointegrated interface establishes a stronger bone-implant bond with increasing time. Although these results do not preclude the possibility that other materials or systems could lead to similar results, only osseointegrated implants have shown at present a long term success.

种植体的骨锚定是一个复杂的问题，不仅取决于所使用的材料，还取决于其他变量，如种植体的宏观和微观结构、手术技术、种植体加载的时间和方式以及宿主骨的状态。bramatnemark等人在使用骨整合种植体修复完全无牙患者的康复方面取得了良好的临床效果。15年90%或以上的成功率与一个基本事实有关:直接骨-钛连接，没有任何纤维组织的干预。与纤维组织界面相反，随着时间的增加，骨整合界面建立了更强的骨-种植体结合。虽然这些结果并不排除其他材料或系统也能产生类似结果的可能性，但目前只有骨整合植入物显示出长期的成功。

[Intramural unilocular ameloblastoma]. [单眼内成釉细胞瘤]。
Stoma (Lisbon, Portugal)
Pub Date : 1990-01-01
L Cabrita, J Boléo-Tomé, A S Cunha

The authors fully describe and discuss one of the first cases of intra-mural unilocular ameloblastoma to appear in Portuguese medical literature. Conservative treatment (enucleation or curettage) was given in the case of the patient presented, and it was possible to follow the post-operative evolution over the last two years. At his last clinical examination the patient was well, with almost total recuperation of mentonian sensitivity and quite satisfactory X-rays of bone rehabilitation.

A scanning electron microscope study of the iatrogenic fractures produced by intra-radicular dental techniques. 用扫描电子显微镜观察根内牙技术造成的医源性骨折。
Stoma (Lisbon, Portugal)
Pub Date : 1990-01-01
J Suárez Quintanilla, L A Segade, J M Suárez Quintanilla, J López Ruiz, A Martínez Garcia, M Biedma

Iatrogenic fractures are frequently produced by certain dental techniques, such as lateral condensation or the use of intra-radicular screws or pins. In the present study, we have described these fractures by means of the scanning electron microscope. Although several authors have pointed out the difficulty to visualize the iatrogenic fractures, they can be easily showed under the scanning electron microscope.

医源性骨折通常是由某些牙科技术引起的，如侧缩或使用根内螺钉或钉。在本研究中，我们用扫描电子显微镜描述了这些断裂。虽然一些作者指出医源性骨折难以可视化，但在扫描电镜下可以很容易地显示。

HIV and the dental undergraduate. 艾滋病和牙科本科生。
Stoma (Lisbon, Portugal)
Pub Date : 1989-01-01
B A Smithurst, J G Russell

Reasons are offered as to why it is imperative that the dental undergraduate is familiar with all aspects of AIDS. The epidemiology of the disease is discussed, as are methods of transmission of the virus. A classification is given of the clinical presentation of HIV infection. The classification is based on the system put forward by the Centers for Disease Control, Atlanta. A brief résumé is given of laboratory diagnosis in HIV infection, and of the risk of health care workers contracting the disease. The precautions recommended for use in dentistry as proposed by the Centers for Disease Control are quoted in full. Finally mention is made of the treatment and control of AIDS.

An experimental study of the colour changes in composite resins. 复合树脂颜色变化的实验研究。
Stoma (Lisbon, Portugal)
Pub Date : 1989-01-01
J Suárez Quintanilla, L A Segade

The composite resins are the most frequently materials employed in restorative odontology. One of the shortcomings is the colour stability. Several workers have reported that colour changes can be considerably avoided with use of photo-polymerized composite resins. However, the present investigation demonstrates that several agents, such as coffee, tea and cola, stain photo-polymerized composite resin samples. The maximum staining was observed in the case of coffee followed by tea, cola being the less chromatic agent of the three.

复合树脂是口腔修复中最常用的材料。缺点之一是颜色不稳定。一些工人报告说，使用光聚合复合树脂可以大大避免颜色变化。然而，目前的研究表明，咖啡、茶和可乐等几种试剂会污染光聚合复合树脂样品。最大的染色是在咖啡中观察到的，其次是茶，可乐是三种颜色中颜色较浅的一种。
