Description
Technical field
The present invention relates to a kind of tooth-planting method of improving the jawbone bearing mode, and a kind of swivel nut type mouth cavity planting body, the endosseous implant field belonged to.
Background technology
China is populous nation, but lacks about the understanding of oral health knowledge, and not strong to the consciousness of oral cavity health, China has become the district occurred frequently of oral disease at present.National for the third time oral health epidemiological survey result according to accomplishing in 2006 shows: in, old people's absence of tooth is serious, middle age is 2～6 of absence of tooth per capita, the old people is 11 of absence of tooth per capita, and 61.8% old people is an edentulous jaw.At present, there are three kinds at the common missing tooth restorative procedure of clinical oral: detachable dental prostheses, fixed denture and Dental Implant.Detachable dental prostheses utilizes maintenance mechanism attached on the adjacent tooth in agomphosis place, have freely pluck wear, characteristics convenient for cleaning; But maintenance property and aesthetic property are poor, foreign body sensation is chewed, had in influence, are prone to cause dysphonia.Fixed denture is abutment with the adjacent teeth, by bonding agent artificial tooth is fixed on it, and the patient need not get voluntarily and wear, and has characteristics such as volume is little, comfortable, attractive in appearance, no foreign body sensation; But repair process needs the reconditioning adjacent teeth, can sacrifice normal structure health, and the artificial tooth bottom is difficult for cleaning.
The sixties in 20th century; The breadboard orthopedics expert of Sweden Nobel
professor leader's research group has proposed bone and has integrated theoretical; Successfully researched and developed simultaneously the clinical modern tooth-planting system that is applied to; And accomplished in the world the first routine tooth-planting operation in nineteen sixty-five; So far after, this bio-imitability artificial tooth is developed rapidly and is used clinical.Developing rapidly of simultaneous clinical practice; The intension of modern tooth-planting greatly enriches and grows up; The science that has formed a whole set of rationale, histopathology, surgery, Implant Prosthesis about modern tooth-planting with put into practice system, become an Oral Science specialty with fastest developing speed in this century.Implantation body often is divided into four types with it clinically as the supportive device of artificial tooth: plant, wear the bone plantation in endosseous implant, subperiosteum plantation, the root pipe.At present, what application was the widest at most is endosteal implant, and Branemark, ITI, IMZ, BLB etc. are the famous brand name of domestic and international implantation body.Though the brand of implantation body is numerous at present; But its structure is similar basically with the clinical manipulation process: implantation body has one and is with externally threaded cylindric or cone shape matrix, and matrix is generally processed by metal or bioceramic, the hole that the clinician is similar to size of drill bit preparation and implantation body's profile in the jawbone zone of patient's missing tooth; Then implantation body is implanted in the hole; With the effect of simulation from the body root of the tooth, on matrix, place base station and artificial tooth at last, finally accomplish the reparation of oral cavity missing tooth.This artificial tooth made from planting patterns has the incomparable repairing effect of traditional artificial tooth, is described as the 3rd human secondary tooth.
Though tooth-planting has become a kind of reparation form that doctors and patients are easy to accept at present, and is promoted widely clinical, also has problems itself with regard to implantation body, influences clinical efficacy and success rate.As everyone knows, the oral cavity is a very complex environment, after wherein implantation body plants in jawbone, and the meeting masticatory force that bearing strength differs, frequency does not wait.Classical plantation is theoretical to be proposed; After implanting, implantation body needs experience one section non-loaded healing stage (3～6 months); Could device dummy, and the field of planting expert proposes the early stage load or even the notion of load at once in recent years, and in the clinical comparatively success rate of approval that obtains.But existing implantation body; Because the limitation of integral structure; When bearing load, can form the region of high stress in the zone near alveolar bone ridge top, have document to prove especially, the stress intensity of bone regeneration around implant bone can reduce along with the raising of bone degree of integration significantly.And planting the early stage of healing; The bone regeneration around implant bone is experiencing the bone process of reconstruction, and also generation or degree of integration are very not low for the integration between implantation body and the osseous tissue, and the intensity at interface is very poor; When therefore bearing function load in early days; Existing implantation body will form stress concentration in alveolar ridge crest, forms overload, causes bone resorption; Simultaneously owing to also do not form the integration of real meaning between implantation body and the bone, so implantation body is stable very poor, when bearing the masticatory force of intensity greatly, can cause the fine motion of implantation body, and the fine motion meeting of implantation body at the interface directly influences symphysis; In addition,, cause many complication, and can increase the difficulty that secondary is repaired greatly in case existing implantation body will cause serious injury to the surrounding bone tissue clinical going wrong.Based on above statement, can find out that not only there is the practical problem that influences aesthetics and functional rehabilitation in existing implantation body, and can directly cause the loosening of clinical implantation body and come off.
