Before a dental loss or an area with partial edentulous or the existence of complete edentulous, to be able to replace the masticatory function, aesthetics and phonation can be performed by placing dental implants.
What Are Dental Implants?
Dental implants are elements that are surgically placed inside the alveolar bone to replace the lost tooth. The implants are made of titanium which is a biocompatible element and with a great osteointegration capacity, to integrate and join with the bone.
The implant replaces the root of the tooth, but a subsequent rehabilitation must be performed to replace the lost functions of the tooth. Implant rehabilitation consists of placing a crown on the implant, if it is unique, or the corresponding prosthetic rehabilitation.
What Are The Differences Between A Tooth And An Implant?
The implant is immobile, as if there was an ankyloses, so there is an absence of the periodontal ligament, which does exist when there is a tooth, so if the implant is catheter it reaches the alveolar bone. In an implant, orthodontic forces cannot be made since it is immobile. The tooth preserves the alveolar bone more, however the implant does not prevent resorption because it has no periodontal ligament.
The minimum distance that must be between a tooth and an implant is 1.5 to 2 millimeters and the distance between implants must be 3 millimeters. On the other hand, there is no minimum distance between tooth and tooth. It is important to note that if these distances are not respected there may be bone loss.
What Shapes, Dimensions And Connections Can Dental Implants Have?
Depending on the shape of the dental implants, these can be threaded or impacted, conical or cylindrical, with internal or external connection and have a Switch platform.
The impacted implants were used in the past and a hole was made with a strawberry a little smaller than the implant and then the implant was inserted with blows. Patients with vertigo were not tolerated well. The self-tapped implants are placed by a prior milling of the bone and a subsequent charge of the implant. Conical implants have more friction and more retention, therefore they are more stable implants, which is very important in those of immediate loading.
The connection is a piece that prevents the implant from rotating. When there is an external connection it avoids it more. It is important that in unit implants the connection is external, however in implants with several pieces it is not necessary, because it will no longer rotate so much and internal connections can be used. The disadvantage of the external connection is that it does not resist lateral forces so much, which can cause more marginal filtration. With the internal connection it is more difficult to parallelize the implants.
The Switch platform prevents recession, so it is very useful in previous sectors. To place a prosthesis smaller than the implant so that the soft tissue invades that area and stabilizes it even more, and it is important especially in the anterior area. The implant will be larger than the prosthesis.
If you talk about the dimensions, the length of dental implants generally varies between 5 to 16 millimeters, they are considered short if they are less than 10 millimeters. There are a type of implants called zygomatic implants that are up to 50 millimeters in length and have a connection at an angle of 45 degrees since they are implanted in the zygomatic bone, cross the maxillary sinus and reach the palate.
Depending on the diameter of the dental implants these can be considered narrow, standard or wide. The straits have a diameter of between 3 and 3 millimeters and a half and are used in narrow areas such as lower incisors or upper lateral incisors. The diameter of standard implants varies from 3.75 to 4.5 millimeters. Finally, wide implants have a diameter of 5 to 7 millimeters, used in case of having to put short implants to gain contact surface.
