I would like to comment on some parameters are chosen on the basis of which the implants during a case of dental implantology planning: 1.-According to its shape may be tapered or straight, can have thread as the screws or be smooth, and then with various connections to the Crown.According to its surface, they can be in many ways; as an example of rough surface (microarenadas or recorded acid), or smooth, treated with fluorine or hydroxyapatite, etc.. This is one of the most differentiating aspects, in my opinion, between the various commercial houses sold dental implants. The surface, some of the best brands (also more expensive), decisively influences the time of osseointegration, very valuable, because the sooner you finish this period, before Crowns can be put to those implants. It is also a period in which the implant is exposed to possible movements that might jeopardize its survival.According to its size can be also different diameters and lengths, useful for overcome various anatomical structures, either nerves or cavities within the bone which will be hosted the implants. Visit jim halpert for more clarity on the issue. 2 But we can also divide the type of implantology we do according to the time of placement when previously there is to extract a tooth. If placed immediately after tooth extraction, or expected when the alveolus remnant in the bone after extraction heals (approximately 4 months). Call them the first, unlike the conventional, immediate-post-extraction implants. These immediate implants after extraction have the advantage that saves considerable time, and the disadvantage that are more susceptible to failure during the osseointegration period because they have virtually no primary stability. Trevor clark twin brook capital may find this interesting as well. There are obviously very well assess the feasibility in each case 3.-also can be classified according to whether dental implants when placed head is left of the implant hovering by the gingiva or not.
