Abstract

Implantoprotetika je disciplina dentalne medicine koju karakterizira izvanredan razvoj materijala i tehnika rada. Svrha je ovoga rada sistematično prikazati znanstvenu podlogu i suvremene koncepte implantoprotetske rehabilitacije u estetskoj zoni.
Prilikom implantoprotetske rehabilitacije u estetskoj zoni treba voditi računa o 10 ključnih parametara: klinički pregled i procjena estetskog rizika, planiranje terapije na tomogramu, atraumatska ekstrakcija zuba, ugradnja implantata u 3D ispravnom položaju, upotreba uskih implantata, nadomještanje kosti u bukalnom procijepu, podebljavanje bukalnih mekih tkiva, modeliranje izlaznog profila, uzimanje otiska i konačni protetski rad. Postoje četiri vremenska modaliteta ugradnje implantata nakon vađenja zuba: imedijatna, rana nakon cijeljenja mekog tkiva, rana nakon djelomičnog cijeljenja koštanog tkiva i kasna. Iako je imedijatna ugradnja implantata jednako uspješna kao i rana i kasna, te smanjuje broj operativnih zahvata i čuva kost i meko tkivo, odluka o vremenu ugradnje mora biti utemeljena na biološkim parametrima, prvenstveno biotipu i stanju bukalne kosti i gingive. Debljina i cjelovitost bukalne kosti izuzetno su bitne jer tanki biotip i oštećenja kosti dovode do nepredvidljivosti estetskog rezultata, a biotip sluznice je vjerojatno najvažniji čimbenik u planiranju implantoprotetske rehabilitacije u estetskoj zoni jer o njemu ovisi količina resorpcije kosti i dugoročne recesije gingive. Precizna 3D ugradnja implantata i obavezna augmentacija bukalnog procijepa u dvije zone preduvjeti su za postizanje dugoročno predvidljivog estetskog rezultata, a vrijeme izrade individualiziranog provizorija ovisno je o biotipu gingive. Socket shield tehnika potencijalno može prevenirati mnoge probleme koji se javljaju kod
implantacije u estetskoj zoni, ali su potrebna dodatna istraživanja kako bi se utvrdila dugoročna održivost postignutih rezultata.

Abstract (english)

Implantoprosthetics is a discipline of dental medicine characterized by remarkable development of materials and techniques. The purpose of this paper is to systematically present the scientific background and contemporary concepts of implantoprosthetic rehabilitation in the aesthetic zone. When performing implant-prosthetic rehabilitation in the aesthetic zone, 10 keys should be considered: clinical examination and aesthetic risk assessment, CBCT planning, atraumatic
tooth extraction, implant placement in the 3D correct position, use of narrow implants, buccal gap bone augmentation, buccal soft tissue augmentation, emergence profile management, impression technique and final prosthetic restoration.
There are four implant placement options after tooth extraction: immediate, early after soft tissue healing, early after partial bone healing, and late. Although immediate implant placement is as successful as early and late, and reduces the number of surgeries and preserves bone and soft tissue, the timing of implantation must be based on biological parameters, primarily the biotype and condition of the buccal bone and gingiva. The thickness and integrity of the buccal bone are extremely important because thin biotype and damaged bone lead to an unpredictable aesthetic result. Soft tissue biotype is probably the most important factor in the planning of implant-prosthetic rehabilitation in the aesthetic zone as it defines the amount of bone resorption and long-term gingival recession. Precise 3D implant placement and compulsory dual zone buccal gap grafting are prerequisites for achieving a long-term predictable aesthetic result, and the time of individualized provisional fabrication depends on the gingival biotype. The socket shield technique can potentially prevent many of the problems that arise with implantation in the aesthetic zone, but additional research is needed to determine the long-term
viability of the results achieved.
