Abstract

Potpuna bezubost u mandibuli predstavlja izazov u izboru terapijskog plana. Ne postoji univerzalan oblik terapije, pogodan za svakog pacijenta te superioran svim ostalim opcijama liječenja. Zahtjevi pacijenata individualni su te modificirani psihosocijalnim, ekonomskim, kulturološkim faktorima te spolom i dobi. Zbog neodstatka koštanog volumena te neposredne blizine donjeg alveolarnog živca kod ekstremne atrofije mandibule otežana je implantološka terapija konvencionalnim implantatima. U takvim kliničkim uvjetima indicirani su dodatni kirurški zahvati u kojima se prvo nadoknađuje volumen izgubljene kosti kao što su vođena koštana regeneracija, horizontalna i vertikalna augmentacija koštanim blokom, distrakcijska osteogeneza, transpozicija donjeg alveolarnog živca te ridge-split tehnika. Takvi zahvati produljuju tijek terapije, predstavljaju dodatan financijski izdatak,a mogu uzrokovati i brojne komplikacije. „Short“ implantati definirani su kao implantati sa 8 ili manje mm intrakoštane duljine. Djeluju kao predvidljiva minimalno invazivna alternativa augmentaciji grebena. Modifikacijom oblika i dizajna navoja, povećanjem mikroporoznosti površine donjeg dijela tijela implantata, te razvojem glatke cervikalne površine obogaćene ionima kalcija ili hidroksilapatita značajno se poboljšalo učinak oseointegracije. Dobra primarna stabilnost pri ugradnji implantata preduvjet je za protokol imedijatnog opterećenja te trenutnu obnovu funkcije stomatognatog sustava u potpuno bezubih pacijenata. Primarna stabilnost tijekom cijeljenja glavni je čimbenik koji utječe na kvalitetu oseointegracije te prognozu implantata. Primjenom osnovnih biomehaničkih principa u implantološkoj terapiji osigurava se predvidljiv i stabilan rezultat.

Abstract (english)

Complete mandibular edentulism represents a challenge in choosing a therapeutic plan. There is no universal therapy form, suitable for every patient and superior to all other treatment options. Patient requirements are individual and modified by psychosocial, economic and cultural factors, as well as gender and age. Due to the lack of bone volume and the close proximity of the lower alveolar nerve in extreme mandibular atrophy, implant therapy with conventional implants is difficult. In such clinical conditions, additional surgical interventions are indicated in which the lost bone volume is first compensated for, such as guided bone regeneration, horizontal and vertical bone block augmentation, distraction osteogenesis, transposition of the lower alveolar nerve, and ridge-split technique. Such procedures prolong the course of therapy, represent an additional financial expense, and can cause numerous complications. "Short" implants are defined as implants with 8 or less mm of intraosseous length. They act as a predictable minimally invasive alternative to ridge augmentation. By modifying thread shape and design, increasing microporosity of the implant bodies' lower surface and developing a smooth cervical surface enriched with calcium or hydroxylapatite ions, the effect of osseointegration was significantly improved. Good primary stability during implant placement is a prerequisite for the immediate loading protocol and immediate restoration of the stomatognathic system function in completely edentulous patients. Primary stability during healing is the main factor affecting the quality of osseointegration and implant prognosis. By applying the basic biomechanical principles in implant therapy, a predictable and stable result is ensured.
