Description
Technical field
The invention belongs to the field of medical instrument technology, have the function of alveolar ridge bone topography measurement more particularly, to one kind
Positioning device for tooth planting.
Background technique
After absence of tooth, there are many repair modes, and tooth-implanting is increasingly becoming a kind of mainstream selection.Tooth-planting technology
Basic principle is threaded cylindrical (or taper) artificial tooth root to be implanted into alveolar bone, to planting body and bon e formation bone knot
After conjunction, then in planting body upper end connection base station, repair corona.As it can be seen that the basis of tooth-implanting is the sclerotin that must have sufficient amount, and
Determine that the most critical factor of plantation success or failure is whether planting body can obtain sufficient bone support.Each face of the planting body of implantation is all
There is certain thickness sclerotin to wrap up, otherwise may cause plantation failure.However, alveolus ostosis is held after due to absence of tooth
Absorption, atrophy, the reconstruction of continuous property, bone pattern become irregularly, and individual difference is very big.Grasp the bone pattern knot of edentulous region alveolar ridge
Structure (mainly height and width) is the premise for carrying out Dental implantion, is selection planting body thickness, the foundation of length；At selected good kind
After implant, direction is properly implanted --- it is directed toward the cheek-tongue direction midpoint of sclerotin, is to guarantee that the cheek-tongue side of the planting body after implantation has
The key of the sclerotin of uniform thickness.
Although often using oral cavity CBCT by CT() it checks, sclerotin width and height can be measured on CT image, such as
Measurement position in CT digital picture is corresponded in patient's mouth, is difficult to solve by what.Current best solution is to be based on
CT data establish mathematical model, choose suitable planting body, and make the 3D printing plantation guide plate of individuation, utilize tooth or bone
Face positioning, determines suitable implant trajectory.However, 3D printing plantation guide plate production is expensive, kind is considerably increased
The cost for planting tooth, also increases the financial burden of patient, thus is difficult to be widely applied.Especially in base's dental clinic, even
Alveolar bone three-dimensional measurement is carried out in the preoperative CT that can not shoot of tooth-implanting, needless to say makes 3D printing and plants guide plate.
Therefore, it develops a kind of cheap and measurement alveolar ridge bone pattern with versatility and assists determining for plantation guiding
Position device has great research significance and application value.
Summary of the invention
