INVENTION
Russian Federation Patent RU2269970
METHOD intraosseous implantation
Name of the inventor: Fikret Abdullayev Mavludinovich (RU)
The name of the patentee: Fikret Abdullayev Mavludinovich (RU)
Address for correspondence: 367027, Makhachkala, Prospect Akushinsky 32A, kv.4, FM Abdullayev
Starting date of the patent: 2002.08.16
The invention relates to medicine, namely to the field of stomatology and may be used for stimulating osteogenesis during intraosseous implants. The technical result of the invention consists in the stimulation of bone formation around the implant and prevent the atrophy of bone tissue around the implant in the cervical area. A method of stimulating bone formation when implanted intraosseous comprising creating and administering the implant bed, which turns under the influence of the load of the chewing subjected to elastic deformation zones forming compression and tension which leads to recovery and regeneration of bone tissue around the implant level.
DESCRIPTION OF THE INVENTION
The invention relates to medicine, namely, to stomatology and may be used in operations to restore the intraosseous implantation defects dentition.
Known method of restoring the defects of dentition with an implant (Massarsky A., 1992. Russian Patent №2028122). Known and the method of direct intraosseous implantation Reimplant (SU patent 2043087, cl. A 61 C 8/00, 1995). This method is taken as a prototype.
Known methods for direct implantation, i.e. immediate replacement of the extracted tooth implant, provide peel muco-periosteal flap, removal of the tooth root, antiseptic treatment of wells, establishment of the implant bed mills, the introduction of intraosseous implant, filling defects between the wall of the hole and the implant osteoplastic materials autobone et al., stitching wounds.
However, the known methods and implants used construction does not provide a reduction in the duration of treatment in operations intraosseous implantation and prevent atrophy of bone tissue around the implant in the cervical area.
The aim of the invention is to stimulate bone formation around the implant and prevent atrophy, better functional and aesthetic results, the reduction of treatment terms for operations intraosseous implantation.
This object is achieved in that the method employs intraosseous implant consisting of the apical part with broad thread windings and the cervical part of conical shape with a conical multiple threads, with the introduction of which into bone tissue creates compression and vertical traction between apical threaded and cervical portion, which are different in bone density, under the influence of the windings of the implant exposed chewing load elastic deformation zones forming compression and tension which leads to the formation and increase bone level.
Standard thread profile of conventional screws has a dependency profile height and diameter, ie, Profile height is determined by the difference between the outer and inner diameter of the screw and is regulated by GOST.
The method used an implant with a high thread profile, i.e. custom profile, above standard with the same diameter, having no strict dependence on the diameter of the screw. Such thread screws are used in screw-porous materials. an implant thread has wide thread windings forming the horizontal plates.
The apical part of the requested parameters with the profile has windings which, when introduced into the bone tissue and gum impact load subjected to elastic deformation zones forming compression and stretching process which results in compaction and formation of bone tissue. Bone tissue to form in the apical part of the implant turns, climbs along the windings to the cervical part of the conical shape of the threaded portion of the turns which should be in the compact cortical bone, which occurs due to the implant hold in place. Compression and vertical thrust and is created between the thread and the apical part of the cervical, which are different in bone density. The conical part of the cervical, the threaded better fixed in the compact bone and increases the compression and traction. The rise of the bone usually occurs before the first threads of the cervical part and compensates for atrophic processes. The method can be used for immediate and delayed implantation, i.e. After healing wells.
The process is as follows.
When a patient is removed direct implantation tooth root cutters well treated is introduced intraosseous implant consisting of the apical part with a special thread, which has a triangular profile the angle of 35-55 degrees, and a pitch of 0.6 to 2.0, and the cervical part of conical shape with conical multiple threads, whereby a portion of the alveolar bone and the implant osteotomy wall exposed internal compression, outside the compression alveolar bone is subjected to compression by the upper edge of the alveolar bone plug is set around which the mucous membrane is sutured, after 3-4 weeks cap unscrewed, set head and effect a locking of the prosthesis, after which under the influence of variables masticatory loads implant threading zone in bone occur zone (compression and expansion) and the vertical compression thrust causing the formation and growth of new bone tissue. The process is supported by clinical examples.
1) The patient 37 years deletes 34. The diagnosis: a deep tooth decay by 34 Ceramic prosthesis. After removing the root curettage was performed, well it is treated with antiseptic solutions. Then special cutters formed a bed for the implant. The hole filled with blood was placed the implant with a high thread profile and tapered cervical part of the threaded implant is injected with compression. The implant is inserted plug, the wound sutured. After 3 weeks, I conducted the second phase - the head was installed, removed the casts. The control ortopantomogrammu found a lack of bone in the distal area of the implant. bone level below the base level of the cervical part of the implant. Fixed bridge implant and 38. After 3 months after fixation of the prosthesis on the control rengenogramme (ortopantomogrammu) revealed a significant rise in the level of bone tissue.
2) The patient 34 years old, diagnosed with a defect of dentition due to the destruction of the tooth 36. The patient were treated by the claimed method. Two of the implant is established. The control radiograph, taken after the operation, determined by the presence of parts of the cervical part of the implant is not in contact with bone tissue. After 3 months, the impact of chewing loads on the radiograph indicated education and raising the level of bone tissue in the area of the implant. Functional results are good.
Use of an implant with a high profile thread (screw) can significantly increase the load bearing capacity of the implant in cancellous bone, shorten the traditional prosthesis with direct implantation (for 3 weeks) due to good initial fixation, greater area of support and the implant ability of this form to better distribute the load on the bone tissue. Compression of the implant area contributes to the rapid introduction of the process of compaction and defect compensation without or with minimal use of osteoplastic materials. Profile implant threads on the apical portion exposed masticatory loads undergoes elastic deformation to form a zone of compression and expansion, resulting in compaction processes occur, and formation of bone tissue lifting. Suturing the mucosa around the cap, without total isolation contributes to wound drainage (implant serves as drainage) and rapid healing process.
CLAIM
A method of stimulating bone formation when implanted intraosseous comprising creating and administering the implant bed, characterized in that the implant is applied, under the influence of the windings which are exposed to load the chewing elastic deformation zones forming compression and tension which leads to recovery and regeneration of bone tissue around the implant level.
