Abstract

The utility model relates to a dentistry appliance. The structure of the utility model comprises a planting pile 1, a cervical part 2 and an implanting body 3. A subsection of a planting body is the implanting body, the cervical part and the partial planting pile become one section, and other parts of the planting pile are the other section; two sections of bodies are in splicing fit through a hexagonal station hole at a connecting position, and are fastened and connected by a fastening screw in a center hole. The utility model simplifies the treatment process of mouth rehabilitation through the structural improvement of a subsection form of the planting body and threads on the surface of the implanting body, the inlaid integration of the planting body and a bone is more reasonable, and position fixing force is obviously strengthened. Therefore, success for planting dentures is promoted, and the service life of the planted dentures is extended.

Description

Two sections non-buried type implantation bodys

This utility model relates to a kind of dental instrument, specifically a kind of manual tooth planting's body.

Tooth is one of indispensable function organ of human body, behind the absence of tooth can to the patient bring chew, a series of problems of function of pronunciation, outward appearance and psychological aspects, therefore be necessary to come the chewing of compensatory dermal tooth, verbal function, and keep the attractive in appearance of face by the oral cavity repairing and treating.Implant denture is a kind of novel mouth mending material that develops rapidly in recent years, and it supports artificial tooth with the artificial growth body of implanting jawbone, makes patient's masticatory efficiency return to degree near dermal tooth.The success or failure of implant denture are that can it retain more than 5 years and bring into play every function in the oral cavity, and each links such as the structure of artificial growth body, material and Oral Repair treatment are to the success rate of implant denture with considerable influence is all arranged service life.Therefore, how improving the success rate and the service life of implant denture, is one of problem of constantly exploring in the tooth-planting medical domain.The two-part implantation body that uses includes implant post, cervical region and implant three parts at present, so-called two-part is that implant post and cervical region are made as one section, implant Dan Weiyi section, have Liu Fangtai, hole to peg graft two sections junction and cooperate, the trip bolt in implantation body's centre bore is fastenedly connected two segment bodies.The operative process of this two-part implantation body is to cut gingiva earlier under local anaesthesia, turns over lobe and is equipped with the hole, replants into the implant section, sews up gingival mucosa.Window at the gingiva position of relative implant again after several months, implantation body's epimere is pegged graft, screw, finish implant operation with screw.Because operation is that the implant section is imbedded in jawbone and the gingiva fully for the first time, so class two-part implantation body is embed-type implantation body.Though use the operative treatment mode of this implantation body simpler, need two operations to finish, both increased patient's misery, the success that increases implant denture because of the chance of traumatic infection has a negative impact again.

The purpose of this utility model just provides a kind of two sections non-buried type implantation bodys, to overcome the drawback that implantation body was produced of using existing structure, further simplifies operation technique, improves the success rate of implant denture.

This utility model is achieved in that implantation body still includes implant post, cervical region and implant, three parts still are divided into two sections, have Liu Fangtai, hole to peg graft cooperates two sections junction, trip bolt in implantation body's centre bore is fastenedly connected two segment bodies, the segmentation of implantation body is that the part implant post of implant, cervical region and 1.5-2 millimeters long becomes one section, and the implant post of remainder is another section.Use the operative process of this implantation body to be, directly be equipped with the hole, implant implant and cervical region one section from gingival mucosa, gingival mucosa exposes the implant post of 1.5-2 millimeters long outward, can directly the plantation pile cutoff be pegged graft with the implantation section after several months cooperates, and screws with screw, finishes implant operation.Because first section implantation body has part to be exposed to outside the gingiva when implanting, for the difference prior art, so be referred to as two sections non-buried type implantation bodys.And the implant post that exposes outside gingiva can not touched with other tooth interlocks, so can the healing of jawbone wound surface do not had a negative impact below 2 millimeters.

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the partial enlarged drawing of implant surfaces helicitic texture in this utility model.

As shown in Figure 1, this implantation body has changed the disconnection position of traditional two-part implantation body, and the part implant post of implant 3, cervical region 2 and 1.5-2 millimeters long is made as one section, and remaining top implant post 1 is another section.Bottom surface at epimere implant post 1 is shaped on Liu Fangtai, and the end face of hypomere implantation body has interior hexagonal hole, pegs graft and cooperate in the platform hole, and the trip bolt 4 in implantation body's centre bore is fastened together two sections transplanting bodies.Matching component as this implantation body also includes cover screw fixture cover, coping screw etc. certainly.

Use this implantation body, can save operation for the second time, simplified operation technique, reduced patient's misery of performing the operation, key point also is once to be equipped with the hole and implants on gingival mucosa, do not have surgical wound for the second time, thereby can make gingiva form better gingiva big envelope at implant neck, this is one of key factor of impelling the implant denture success, can improve the success rate of implant denture thus.

Be further to improve the service life of implant denture, also the surperficial external screw thread of implant in this implantation body 3 can be made for drift angle is that arc, pitch are the version (see figure 2) of 1.5-2 millimeter at 80-95 °, the bottom of thread.The thread vertex of this helicitic texture near or equal the right angle, thicken greatly than the existing ridge that is 35 ° of drift angles to the maximum, and the wedge angle that changes the original thread bottom is a curved bottom, this has just fully adapted to jawbone osseous tissue characteristics, sclerotin and screw thread contact surface are increased, implantation body and sclerotin are inlayed and are integrated closelyr, and maintenance power further strengthens.The also increase of more common implantation body of thread pitch in this implantation body simultaneously, the biomechanics characteristic that this has just further adapted to loose sclerotin makes the pressure conduction of implantation body more reasonable, thereby has improved the ability of chewing and the loosing prevention ability of implant denture.Thus, use the special-shaped thread implant of this coarse pitch can prolong the service life of implant denture.Simultaneously, the special-shaped helicitic texture of this coarse pitch is also applicable in other various forms of implantation bodys.

This utility model is by the improvement to implantation body's segmentation form and implant surfaces helicitic texture, the Oral Repair therapeutic process is simplified, and implantation body and sclerotin are inlayed and are integrated more rationally, and maintenance power obviously strengthens, promote the success of implant denture thus, prolonged the service life of implant denture.
