Abstract
The invention discloses a dental implant assembly, which is characterized in that the diameter of the neck portion is slightly larger than that of the body portion of the dental implant and has a taper, the implant body portion has a dental root shape, the root portion of the dental implant has a self-tapping cut groove, the dental implant is provided inside with a Morse taper mechanism for fillet positioning, the neck portion is provided inside with a stepped cylindrical surface that is in clearance fit with an abutment, the junctions between the abutment and the dental implant are positioned on the stepped cylindrical surface, and the diameter of the upper part of the abutment is larger than that of the dental implant. The clearance between the abutment and the implant is helpful for in-growth of gingival and bone tissues. After implantation in vivo, the stress position for bondage between the dental plant and the abutment descends to prevent alveolar resorption due to overload on the neck portion of the dental implant; the marginal size of the abutment is enlarged to avoid food debris from entering implantation zone during chewing process. Additionally, the dental implant assembly fits well with a nut cap, thereby realizing implant esthetics.
Description
Technical field:
The present invention relates to medical apparatus and instruments, is a kind of threaded implantation body and supporting with it base station in the alveolar bone, mouth cavity planting body device of block screw composition implanted specifically.
Background technology:
The sixties in 20th century, professor Branemark of Switzerland Gothenburg university has carried out having founded " synosteosis " theory about tooth-planting material and bone-implantation body's Study of Interface, for theoretical basis has been established in the application of oral implantology.The tooth-planting application technology is a most important part in the modern oral implantology.Extensively the carrying out and use a series of attractive in appearance and first-class problem of function that missing tooth clinically brings that solved of tooth-planting artificial tooth.Yet the success rate at a specified future date of implantation body still is worth us to inquire into and worry: As time goes on, alveolar bone begins to occur absorbing; Cooperate between base station and implantation body begin to occur loosening; Connecting screw is long-term stressed and fracture; The intrusion of microorganism and antibacterial etc., make bone regeneration around implant occur inflammation, loosening, base station comes off etc., finally causes the undesirable base station repairing failure of implantation body's repairing effect.
Summary of the invention:
The present invention seeks to overcome above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, combines effective, as to have gingiva aesthetic effect mouth cavity planting body device with alveolar bone.
The present invention can reach by following measure:
A kind of mouth cavity planting body device, comprise implantation body, base station, the block screw formed by cervical region, body and root, feature be the implant neck slightly larger in diameter in the body diameter and have tapering, the body of implantation body adopts the root of the tooth type, implantation body's root has the self tapping cutting slot.
The present invention adopts Morse's taper to cooperate the filleted corner location in implantation body's internal structure, its inner neck portion is provided with the ladder face of cylinder, be combined with minim gap between the ladder face of cylinder and base station, be beneficial to gingiva tissue or osteocyte enters, be respectively equipped with detent and positioning boss in the implantation body inner Morse's taper hole and on the base station Mohs awl bar that is mated, so that implantation body is connected with base station is more reliable, more firmly and easily base station and implantation body are mounted and dismounted, below, the Morse's taper hole of implantation body inside is provided with the technology screw, with between the dismounting that makes things convenient for base station and healing stage with being connected of block screw.
Base station of the present invention and implantation body's contact point are positioned at the step face of cylinder, and the base station upper diameter is greater than implantation body's diameter, and the matrix of implantation body upper end is provided with umbrella limit shape boss, prevent that the chip that tooth produces in the process of chewing from directly falling into implantation body gingival edge inside.
Implantation body of the present invention structure Design helps the initial stage synosteosis, the bigger generation bone of recess diameter squeezing action, avoid in implantation body's initial stage unstability that operation process middle and upper part enlarged-diameter causes, base station connecting portion and implantation body's superstructure have small gap, be beneficial to gingiva tissue or osteocyte enters, after implantation body is stressed, reduced the frontal resorption of implantation body's superstructure, move down by making implantation body combine the stress point position with base station, reduced the implant neck structure because of the stressed excessive frontal resorption that causes, enlarge implantation body's base station marginal dimension, make the base station size greater than implantation body's superstructure, the chip of having avoided tooth to produce in the process of chewing is directly fallen into implantation body gingival edge inside, implantation body connects employing taper fit fillet locate mode, make base station be connected the location with implantation body and put in place that reduced that center screw is stressed fractures because of matching loose causes connecting, healing block special shape and implantation body are connected and help the gingiva aesthetic effect.
The invention has the beneficial effects as follows: 1, base station connecting portion and implantation body's superstructure have small gap, be beneficial to gingiva tissue or osteocyte enters, after implantation body is stressed, reduced the absorption of the alveolar bone of implantation body's superstructure, 2, move down by making implantation body combine the stress point position with base station, reduced the implant neck structure like this because of the stressed excessive frontal resorption that causes, 3, enlarge implantation body's base station marginal dimension, make the base station size greater than implantation body's superstructure, the chip of having avoided tooth to produce in the process of chewing is like this directly fallen into implantation body gingival edge inside, 4, healing block special shape and implantation body are connected and help the gingiva aesthetic effect.
