SHORTS DENTAL IMPLANTS

There is a significant number of patients who have become worried wondering whether they can dental implants without the whole process of bone grafts and membranes, which of course is related to the increased budget of the surgical procedure.
Considering these 6 years of experience placing short implants I decided to briefly explain the scope of this technique.
First, we must say that for short implants we mean those whose length is less than 10mm.
We can see the dotted line with reference to a length which must be less than 10mm.The lengths are variable and depend on the trading house reference. Like all surgical techniques always have advantages and disadvantages which we will see later.
When we talk about one of the first things we have in mind dental implants is the "primary stability" of the implant, this means that if an implant is not completely fixed in the bone when placing, if you have any clinical degree of mobility the implant will not integrate into the bone, so we will not have what we seek is the osseointegration. It is not hard to deduce that while longer the implant will have more chances of achieving primary stability, but not only influences the length of the implant in such stability, it is also the diameter of the implant.
In this case the dotted lines represent the implant diameter (width) which varies according to the shape of the implant.
The diameter is a very good way to compensate for the reduced length of the implant, because if we increase more surface contact with the bone then obtaining primary stability.
So far we have only talked about the length and diameter of the implants, but we are missing something very important and is the amount of bone available and its quality.
In this regard, we have technical limitations and is setting an example: if I have a short implant of the following measures: 3.75mm x 6mm but the bone that the patient has 2.0mm x 3.5mm is (try to locate three-dimensionally), then we have a problem of bone volume both high and wide and would not be possible to place the dental implant in this case. Means for selecting the technique of short implants, bone remnant require a minimum which must be met in order to carry it out. When you do not have the proper surgical bed then it's time to think about bone grafts or other techniques to increase the host bone.
We also say that the more procedures are associated with the placement of a dental implant or more, the higher the failure rate of the same, ie, placing a dental implant on a healthy bone is more predictable, which put the same dental implant on a site after a tooth extraction, with little remaining bone with bone graft, with membrane placement.
Are natural or anatomical limits that should be considered as boundaries that can not happen, we can say that (in general) in the maxilla have for the case of the upper incisors as an upper limit the nasal floor, while for premolars and molars have the maxillary sinus. In the case of the mandible our limit in the lower incisors will be the base of the jaw and premolars and molars the canal of the inferior alveolar nerve and the exit hole for the mental nerve (the intraosseous nerve path, which gives sensitivity the lip and teeth). But we say again, we talk about surgical techniques, this means that with respect to other techniques can: move, alter or modify these anatomical limits to our convenience.
Leaving aside these generalities, we can now say, and supported by the international scientific literature, that the short dental implants are successful, predictable technique and is indicated in cases where it is not possible to place implants longer. We can also say that short implants from the point of prosthetic and functional standards meet the long-term success when properly executed.
Personally, I can say that it is a highly sensitive technique operator, and really that's where success lies. We always insist that dental implants are a set of surgical techniques to be adjusted to the patient and not the reverse, a maxillofacial surgeon is able to develop all kinds of techniques, from the placement of dental implants in conventional manner, to those more complicated in patients with sequelae of fractures with loss of substance, after extensive resections bone cysts or tumors of the jaws, among others.
CLINICAL CASE, SHORT IMPLANTS:
Female patient 45 years of age, which interconsultation for dental implants, comes with Dental Tomography (CONE BEAM CT) with a subsequent diagnostic impression of implants lower right molar area (left on the screen) to bone regeneration (graft osseous)
