Some aspects of periimplantitis

In recent years, dental implants are gaining great momentum in developed countries. Scientific observations and studies of clinicians demonstrate good results of implantation, which allows to achieve a full restoration of chewing efficiency, speech formation and aesthetics of the dentition [5,6]. The problem of finding the optimal technologies of implantation, as well as methods of prevention and treatment of periimplantitis is relevant to date and includes not only the development of new methods of surgical interventions, the use of additional measures during prosthetics, but also the creation of new implant systems that fully meet the requirements of prevention of inflammatory diseases in the periimplantation zone[1,4,8]. With the development of dental implantation in dentistry appeared complications such as peri-implantation mucositis and peri-implantitis. Peri-implantation mucositis-inflammation of soft tissues near the implant without violation of osseointegration. Periimplantitis is an inflammatory reaction of the tissues surrounding the osteointegrated implant accompanied by loss of the supporting bone [6,2]. To distinguish between both complications can be radiologically and, if mukozita the implant is not mobile in the alveolar ridge, and when implantate celebrated his mobility [2]. Diagnosis of periimplantitis is carried out through visual and instrumental examination of the oral cavity, during which edema, redness of the mucous membrane and bleeding of the gums are detected. The palpation method allows to determine the flow of purulent process, as well as the mobility of the implant [2]. The main methods of diagnosis: a sample using a solution of Schiller-Pisarev, revealing the latent inflammatory process, as well as the stage of periimplantitis; CT; periodontal Russell index, which helps to determine the degree and depth of inflammation; bacteriological and biochemical laboratory tests and radiography, allowing to diagnose peri-implantitis in the picture.[5] The purpose of the peri-implant therapy are: to prevent further bone loss, and (ideally) "reactionary" of the implant (new bone formation in direct contact with a previously contaminated implant surface). [3] Full-fledged treatment of periimplantitis is usually carried out in two stages and involves the elimination of gingival inflammation and surgical sanitation of the focus with directed bone regeneration. [1] The most important part of peri-implantitis treatment is to stop the progressive loss of bone by controlling plaque and remove the pocket.  Full treatment usually involves two phases, similar to periodontal therapy. The causally related initial phase consists of the removal of plaque and Tartar. The result is elimination of gingival inflammation [4]. Conservative phase of treatment of periimplantitis includes conducting professional hygiene of the oral cavity, irrigation periimplantation pockets by ozonized solution, laser therapy, mouth trays and applications. Particular attention is paid to the removal of dental deposits from the crown and abutment. If necessary, a modification of the suprastructure is made, which allows to eliminate the biomechanical overload of the implant [6]. In special cases, an attempt to restore bone loss by surgical procedures (directed bone regeneration) is possible. If the initial phase of  therapy is successful, you can start the second (surgical) phase. [5] During the surgical procedure, it is imperative that the infected surface of the implant be completely cleaned.  During surgical stage of treatment of peri-implantitis is an incision and tilting the periodontal flap, osseous revision of pocket, removal of the peri-implant granulation tissue, cleaning the implant surface using special curets or Perio-Flow [2,3,4], detoxification of the implant surface with citric acid, thorough washing of the pocket [6]. The operation ends with the introduction into the bone pocket of osteoconductive material and barrier membrane and suturing the operating wound with a protective periodontal bandage. In the postoperative period, antibiotics and antiseptic rinsing are prescribed. [8] in case of recurrent or far-advanced peri-implantitis, the implant is removed with subsequent re-implantation. [5,7,8]

To prevent the development of peri-implantitis patients should be under the supervision of a surgeon-implantologist and periodontist, to observe the rules of care of teeth and prosthetic constructions on dental implants are to pass the procedure of professional hygiene in the recommended time. The frequency of professional hygiene sessions depends on local and General risk factors for the recurrence of peri-implantitis.[6] in patients with partial Edentia, this periodicity corresponds to the period of periodontological control examinations and depends on the individual situation. The interval between visits varies from two to six months.[2, 4]

Thus, only regular visits as part of maintenance therapy and high-quality individual care will help to reduce the number of complications after dental implantation in patients, improving their quality of life.
