Abstract

Parcijalna ili totalna bezubost, povezana s jakom resorpcijom gornje čeljusti, često je uzrok problema izrade protetskih radova. Resorpcija je posljedica gubitka zuba, a uzrokuje slabu retenciju proteze. Osim toga i neki faktori od strane pacijenta, kao što je jaki podražaj na povraćanje, mogu limitirati nošenje proteze. U slučaju kada klasična protetska terapija nije u mogućnosti kompenzirati resorpciju gornje čeljusti pri terapiji, potrebna je implantološka terapija kao podloga za protetski nadomjestak. Implantacija u gornjoj čeljusti je često komplicirana zbog nedovoljne visine i širine alveolarnog grebena. Insuficijentni koštani volumen je potrebno ispraviti pretprotetskim operativnim zahvatom prije implantacije. Tehnikom elevacije dna sinusa dobiva se potrebna količina kosti za ugradnju endosealnih implantata. Ova tehnika, bazirana na dobrim kliničkim rezultatima, se učestalo primjenjuje u rekonstruktivnoj pretprotetskoj kirurgiji. Elevacija dna maksilarnog sinusa je pouzdana metoda, ako je detaljno planirana i adekvatno napravljena. Komplikacije su moguće i zato kirurg mora znati prepoznati i tretirati preoperativne i postoperativne probleme. Zaključno, elevacija dna maksilarnog sinusa uz augmentaciju koštanim implantatima je pouzdana tehnika, kojom se postižu dugoročni rezultati.

Abstract (english)

Edentulous patients with a severely resorbed maxilla frequently complain of ill fitting upper dentures. The continuing process of resorption, related to loss of teeth in the upper jaw, may evetually result in poor denture retention. Moreover, patient related factors, such as an extreme gagging reflex, may play a role as well. Improvement of prosthodontics may not be sufficient to compensate for the maxillary resorption, additional procedures, such as insertion of endosseous implants to support the prosthetic construction, are needed. However, reliable insertion of implants is often complicated in the upper jaw because of insufficient height and width of the alveolar process. In such cases, the insufficient bone volume of the
maxilla has to be overcome by reconstructive pre-prosthetic surgery before implants can be installed at the preferred sites.
To establish an adequate environment for the insertion of endosseous implants, various grafting procedures have been developed to increase the bone volume. Based on good clinical results, sinus floor elevation procedures are commonly used in reconstructive pre-prosthetic surgery. Sinus floor elevation surgery with autogenous bone grafts is a reliable procedure if properly planned and performed. The procedure is not without complications and surgeon must be able to manage problems that arise peroperatively as well as those that develop in the early and late postoperative phases. Bone grafting of the maxillary sinus floor, with bone augmentation for the insertion of implants, is reliable treatment modality with good long-term results.
