Description
Technical field
This utility model relates to the oral implantology field, particularly a kind of personalized positioning navigation system that is used for dental implantation.
Background technology
Oral implantology is grow up the thirties in 20th century one an independently new and developing branch subject, mainly comprises contents such as implant surgery, implant denture reparation, planting material, plantation mechanics and plantation biology.The implant that wherein plays support, maintenance effect is called mouth cavity planting body, also claims tooth implant usually, promptly is meant the superstructure in order to support that artificial tooth is repaired, and is implanted into the device of artificial material design at the upper jaw or lower jaw jawbone with surgical means.Implantation body is distinguished by implant site in endosteal implant, subperiosteal implant, the tooth internal skeleton implantation body, tansmandibular implant and ramus frame implant etc. in the implantation body and mucosa.So far clinical main application be endosteal implant, profile mostly is column or screw thread column and root pipe taper.
For the anatomical features of jawbone itself, mandibular bone is made up of the lower jaw member of vertical ramus of mandible in both sides and central horizontal.In most cases, the plantation art of lower jaw is carried out in the lower jaw body region.The anatomical structure that the lower jaw plantation notes is mandibular canal and mental foramen.The anatomic form of upper jaw bone is irregular, and, zygomatic process prominent by the body of maxilla volume, alveolar process, palatine process are formed.Implement implant operation and relate generally to alveolar process and body of maxilla.Upper jaw bone body center is a cavity, claims maxillary sinus, and maxillary sinus likeness in form ground taper down constitutes domes by thin hone lamella all around, and its lower wall links to each other with alveolar process of mandible, and bottom cover is crossed upper jaw premolars or first and second tip of a root of grinding one's teeth in sleep.Distance to alveolar process at the bottom of maxillary sinus is too small, when lacking enough osseous tissue supports, generally adopts the sinus lift art to solve the problem of bone quantity not sufficient.
At present, implement dental implantation clinically before, generally can do tooth work model and CT scan, but do not have concrete means accurately to determine the position and the direction of implantation body.Therefore, for the operator that experience lacks, difficulty is bigger, and the plantation success rate is relatively low.
With respect to the anatomical structure of lower jaw complexity on the human body, the clinician determines generally only to come from plane X line sheet or plane CT sheet to the understanding of patient's tooth-planting environment and the direction that implantation body is implanted, position etc. so far.If want from these plane pictures correct direction, position that implantation body on top of implants, need the operator that suitable rich experience is arranged, probalility of success just can be higher relatively, even the direction that the implantation body that operator that rich experiences are arranged grasps implants, position also just one visually, in the human brain imagination or the computed position that obtains after simple the measurement, degree of accuracy is still lower, simultaneously because position and the spatial restriction of operation technique in the operation also makes predicted position and actual position and the direction of implanting very easily produce deviation.In case plantation failure has not only brought bigger misery to the patient, return the patient and bring no small property loss, after all so far, domestic implantation body's surgery cost is still relatively expensive, plants a tooth average cost greatly about about 10,000 yuan.
