Description
Technical field
The present invention relates to a kind of bone face anchoring type dental implant design method and planting body with topological optimization structure.
Background technique
Currently, with society it is increasingly developed, people are higher and higher to the pursuit of stomatological aesthetics.The defect of tooth affects
Oral cavity relationship and also hinder beauty.Tooth-implanting has become agomphosis due to having many advantages, such as that beautiful, comfortable, masticatory efficiency is high
The main selection repaired.But traditional root shape planting body requires completely the more demanding of bone amount, including bone height and bone width
Sufficient implant operation requirement.If carried out in the case where Alveolar bone insufficiency plantation dental restortion there may be failure risk,
Plantation side is caused to be pierced by alveolar bone including bone width deficiency, bone height deficiency causes planting body exposure and primary stability inadequate
Deng.Clinically, due to periodontosis, the case where jaw disease, wound, the factors such as tumour lead to Bone mineral change, is more, limits kind
Plant the application of dental restortion technology.
It is clinically often a small amount of to solve by filling out bone meal and covering periosteum in order to increase the bone amount when plantation of root shape planting body
Bone deficiency problem, or rived by autologous bone transplanting, operation, distraction osteogenesis etc. surgically solves serious Bone mineral change and asks
Topic, but these modes need to first pass through operation and solve the problems, such as bone increment, through recovery after a period of time, then implement tooth implantation hand
Art, operating process is more complicated, and operation number increases, and increases the difficulty of plantation dental restortion and the time for the treatment of, cost of performing the operation
The problems such as higher, while there is also art areas to infect, bone increment is limited.
In fact, one kind is based on before root shape (including cylindricality or taper) the planting body application based on Integrated implant concept
Planting body, that is, subperiosteal implant of the fixed special rack-like structures in bone,subperiosteal face has just had application in generation nineteen thirty.But
It is that its production needs then to manufacture the subperiosteal implant for being close to bone face by forging type by surgical exposure bone face and modulus
Bracket, be then implanted into again by second operation.Since operation is complicated, manufacturing process is longer, operation wound is larger,
Root shape planting body is just gradually eliminated after occurring.But it is directly anchored to bone face, is facing bone amount to solve root shape planting body
Reparation problem when insufficient provides a kind of resolving ideas.Especially in recent years, with medical image acquisition, Maxillary region tissue three
The numbers such as dimension rebuilds, operation plan digitlization careful design, titanium 3D printing and optimization design, biomechanical analysis
The development and application of word technology, the personalized subperiosteal dental implant that bone face is directly anchored complete careful design and system in the preoperative
Make and completes to be implanted into feasibility with higher by disposable surgical.
