一位44岁的女性患者来到一家私人牙科诊所，请求替换她缺失的左上第二前磨牙。为了规划病例，进行了CBCT X光检查。一个偶然的发现是，无症状的左上第一前磨牙的根部有一个根尖病变。这颗牙有根管填充，其根部弯曲朝向植入体将要放置的位置。进行了口内扫描，并将其叠加到CBCT上以规划手术指南。

手术指南设计有两个目的：
– 用于引导手术植入体插入
– 定位根尖病变的确切位置，以便在进行根尖切除手术时进行微创手术

在手术预约期间，在根尖病变区域稍微冠状水平的颊粘膜上进行了切口。抬起一个瓣，将由牙齿支持的指南放置在牙齿上，确保其完美贴合。

通过手术指南中设计的“窗口”使用圆锥形钻头去除覆盖根尖病变的骨“盖”。当这个被移除时，相当一部分肉芽瘤附着在骨“盖”上。

完成根尖切除手术和正确的感染区域去颗粒化后，骨“盖”被放回原位。

用PTFE缝线缝合根尖切除瓣。随后进行了标准的引导手术常规程序，放置了一个C-Tech EL 4.3x11mm植入体来替换缺失的左上第二前磨牙。术后根尖X光片显示了植入体及其愈合基台，以及完成的左上第一前磨牙根尖切除，替换的骨“盖”覆盖在手术部位上。

Conclusion: 2-3 years of tracking clinical cases showed that the effect of bone wrapping surrounding the C-tech implant was significant, with increased bone density, which presented its advantage in the esthetic of anterior teeth.

Conclusion: 2-year clinical tracking of the cases of implantation in the maxillary posterior area showed that the effect of bone wrapping surrounding the C-tech implant was significant, with good root osteogenesis, which presented its advantage in the cases of maxillary sinus elevation.

Conclusion: 3-5 years of clinical tracking showed that in the cases of implantation in the mandibular posterior area, the bone height and bone density surrounding the C-tech implant were increased significantly, with a significant effect of bone wrapping, which fully presented the advanced design and precise processing of the implant.

In the present clinical case, the upper left lateral incisor presented with a vertical fracture. Following a proper clinical and radiographic analysis, the tooth was considered hopeless. The treatment plan consisted of the extraction of the lateral incisor and immediate implant placement. It is well described in the literature that delayed loading, in contrast with immediate or immediate- delayed loading, can lead to predictable results in all clinical situations.

64-year-old female patient who came with an old mixed fixed-mobile prosthesis The patient is in good health and is a non-smoker. The patient expressed the desire to have all her teeth fixed and together with the patient we decide to extract all the dental elements, move away irreversibly and place 6 implants to make a screwed prosthesis.

Watch Dr Henriette Lerner explaining all the features of a successful and qualitative implant.

I saw you have breathing plant systems in the pipeline and you learn a lot of systems, and probably you already have in your mind some main features that the implants need to have.
In order to make your treatment easier and more predictable in your procedures.
You probably already know that an implant has to have a high bone implant contact surface and the designs of the implants are all made in a way that increases this surface, because this is giving you a long-term stability of the surface of the osteointegration.

In which ways has Covid-19 affected implantology?
Covid-19 has influenced and will affect both the private and working lives of many of us. From a working point of view, we have to develop new protocols for patient management, disinfection and operator protection.
For what concern implantology, it is not clear how much it will affect this type of treatment offered to our patients.
