Description

Wing plate implant and old oral implant

Technical Field

The application relates to the technical field of dental implantation, in particular to a wing plate implant and an old-age oral implant.

Background

The implant is comfortable and beautiful, does not damage adjacent teeth, has stable effect, and is the first choice for repairing lost teeth of many patients. The maxillary posterior dental area bears the main occlusal force in the oral chewing process, however, the maxillary posterior dental area has loose bone, and due to the fact that the upper part of the maxillary posterior dental area is adjacent to the maxillary sinus, the bone and the bone quantity are not enough after the teeth are lost, and the requirement of conventional planting on the bone quantity cannot be met. At present, the problem of insufficient bone mass in a posterior maxillary dental area is solved clinically by adopting a short implant or a bone grafting and maxillary sinus lifting technology, however, the failure rate of the short implant is high due to the bone problem in the posterior maxillary dental area, a second surgical area needs to be opened up for alveolar ridge bone grafting, the injury is large, and the risk of bone absorption may exist in a long term; the maxillary sinus promotes and has destroyed the integrality of maxillary sinus, sometimes because maxillary sinus anatomical structure factor causes the maxillary sinus mucous membrane to perforate easily, leads to the bone grafting failure. The functional reconstruction of the edentulous area can also be carried out on the old patient or the patient without the tooth jaw by adopting an All-on-Four method, but the cantilever beam exists at the far end of the prosthesis by the method and has great influence on the long-term stability of the prosthesis and the prosthesis assembly. A large number of clinical studies have shown that cantilever arms, especially those of excessive length, can cause complications such as bone resorption at the neck of the distal-most dental implant, exposure of the screw thread at the upper end of the implant, fracture of the prosthesis, loosening and fracture of the central screw, etc. V-II-V dental implantation, increase the wing plate planting technique (TPP technique) in the far middle of maxilla, namely implant two oblique dental implants in the far middle wing maxilla area of maxillary sinus on both sides of upper jaw on the basis of All-on-Four, can dispel the far end cantilever beam arm to implant prosthesis like this. The advantages of the TPP technique are: bone grafting operation is not needed; the integrity of the maxillary sinus is maintained, and the anatomical structure of the maxillary sinus is not a technical difficulty any more; the success of the implant is expected; the front and back diameters of the prosthesis are increased, no cantilever is arranged, the risk of biomechanical overload caused by the cantilever is thoroughly eliminated, and the success rate of immediate load bearing and long-term repair is improved; the angle of the implant is easy to repair, and the complication is less; the wing maxillary implant can reduce the bending torque of the maxillary sinus mesial inclined implant or the zygomatic implant in a loaded state, effectively increase the long-term success rate of implant repair, and effectively reduce the incidence rate of crest area bone absorption and oronasal maxillary sinus fistula caused by the transverse swing of the zygomatic implant; can carry out soft tissue operation at the same time, can carry out load-bearing repair immediately, and greatly shorten the treatment time. However, the TPP technology has high technical sensitivity, the implant length required by reaching the pterygoid palatine process from the second molar site through the maxillary tubercle is about 13-25mm, and the conventional implant cannot meet the requirement of wing-penetrating plate implantation at present.
