Abstract

Homologna transplantacija ili autotransplantacija je kirurški postupak presađivanja zuba ili zubnog zametka iz jedne alveole u drugu kod iste osobe. Metoda se najčešće izvodi u djece i adolescenata jer je kod njih kontraindicirana implantološka i protetska terapija. Za donorski zub obično se izabire treći molar, premolar, prekobrojni zub ili bilo koji zub za koji se procijeni da je od smanjene važnosti u denticiji. Nakon autotransplantacije zubnog zametka, on dalje raste, razvija se korijen, stvara parodont i čuva vitalitet pulpe, a nakon transplantacije zrelog zuba nema daljnjeg rasta i razvoja korijena, a ne očekuje se ni pojava revaskularizacije pulpe. Od iznimne je važnosti izvođenje kirurškog zahvata uz maksimalno atraumatsku ekstrakciju zuba donora i pažljiva manipulacija prilikom postavljanja u pripremljenu alveolu. Očuvanje Hertwigove epitelne ovojnice prilikom transplantacije zuba preduvjet je za daljnji rast i razvoj korijena. Nakon transplantacije treba razmotriti potrebu za endodontskim zahvatom, a prilikom svake kontrole potrebno je pratiti radiološki nalaz, vitalitet, položaj i mobilnost zuba, zvuk perkusije, stanje gingive i dubinu džepova. Transplantacija se smatra neuspješnom ako se pojavi nekroza pulpe, resorpcija korijena i ankiloza zuba. Ugradnja dentalnih implantata pokazuje visok stupanj uspješnosti i dugoročno predvidljiv rezultat terapije, no transplantacija predstavlja prioritet kod pacijenata sa nedovršenim rastom i razvojem čeljusti. Riječ je o biološkom postupku u kojem zubi, osobito u fazi zametka, imaju potencijalnu sposobnost inducirati rast alveolarnog nastavka, stoga se može upotrijebiti kod pacijenata prije kraja pubertalnog rasta, dok se osteointegrirani implantati ne mogu prilagoditi rastućoj čeljusti pacijenta.

Abstract (english)

Homologous transplantation or autotransplantation is a surgical procedure that transplants teeth or dental embryos from one alveolar to the other in the same person. The method is most commonly performed in children and adolescents when implant and prosthetic therapy are contraindicated. The third molar, premolar, supernumerary tooth or any tooth which is considered to be of lesser importance is usually chosen as the donor tooth. After the autotransplantation of the dental embryo, it continues to grow and develop a root, creating periodontal and maintaining pulp vitality, and after the transplantation of the mature tooth there is no further growth and root development, and no pulp revascularization is expected. It is of utmost importance to perform a surgical procedure with the maximum atraumatic extraction of the donor teeth and careful manipulation when placing it in the prepared alveolus. The preservation of Hertwig's epithelial root sheath during tooth transplantation is a prerequisite for further growth and root development. After the transplantation, endodontic surgery should be considered, and during each check-up it is necessary to monitor X-rays, vitality, position and mobility of the tooth, the sound of percussion, gingival condition and probing depth. The transplantation is considered unsuccessful if it comes to pulp necrosis, root resorption and tooth ankylosis. The implantation of dental implants demonstrates high degree of success and a predictable long-term result of therapy, but transplantation is a priority among patients with unfinished growth and jaw development. It is a biological procedure in which the teeth, especially during the embryonic stage, have the potential to induce alveolar growth, and can therefore be used with patients before the end of puberty growth, while osseointegrated implants cannot adapt to the patient’s growing jaw.
