Abstract

U završnom radu opisani su tipovi dentalnih nadogradnji te proizvodnja i upotreba nadogradnji u kontekstu suvremenih tehnologija. Raščlanjeni su dijelovi dentalnog implantološkog sklopa. Opisano je u kojim slučajevima se koriste dentalne višečlane nadogradnje te njihova podjela. Uspoređena su karakteristike brtvljenja i prijenosa sila ovisno o geometriji spoja nadogradnje i implantata. Prikazano je kako različiti oblici transgingivalnog segmenta nadogradnje utječu na zarastanje gingive. Navedena su ograničenja prilikom montaže zubnog luka na višečlane nadogradnje.
Zatim je sastavljena definicija problema, u kojoj su navedeni nedostaci u postojećim rješenjima. Proučeni su patenti i komercijalna rješenja. Napravljena je usporedba patenata i usporedba komercijalnih rješenja. U svrhu prilagodljivosti dizajna za različite implantate, napravljena su mjerenja kontaktnih ploha između postojećih nadogradnji i implantata. Sastavljen je zaključak i smjernice za razvoj.
Napravljena je funkcijska dekompozicija dentalnih višečlanih nadogradnji, te morfološka matrica. Iz njih su izvedena 4 koncepta. Odabran je koncept za daljnju razradu, te je nakon detaljnije razrade, izrađen prototip 1, tehnologijom 3D printanja. Opisana je tehnologija izrade prototipa. Nakon testiranja prototipa 1, uočena su moguća poboljšanja, te je razrađen i napravljen prototip 2. Napravljen je proračun pomaka i geometrijska ograničenja konstrukcijskog rješenja. Opisan je postupak izrade višečlane nadogradnje i vijka za montažu nadogradnje na implantat. Na kraju su navedene tehničke specifikacije konačnog rješenja.

Abstract (english)

In the final paper, the types of dental extensions and the production and use of extensions in the context of modern technologies are described. The parts of the dental implantology assembly are explained. It is described in which cases dental multi-unit abutments are used and their division. The characteristics of sealing and force transmission were compared depending on the geometry of the connection between the abutment and the implant. It is shown how different forms of the transgingival segment affect the healing of the gingiva. Limitations when mounting the dental arch on multi-unit abutments are explained.
Then a definition of the problem was drawn up, in which the shortcomings of the existing solutions were listed. Patents and commercial solutions were studied. A comparison of patents and commercial solutions was made. To adapt the design for different implants, measurements of the contact areas between the existing abutments and the implants were made. A conclusion and guidelines for development have been drawn up.
A functional decomposition of dental multi-unit abutments and a morphological matrix were made. 4 concepts were derived from them. A concept was selected for further development, and after detailed development, prototype 1 was made using 3D printing technology. Prototyping technology is described. After testing prototype 1, possible improvements were observed, and prototype 2 was elaborated and built. The displacement calculation and geometric limitations of the structural solution were made. The procedure for making a multi-unit abutment and a screw for mounting the abutment on the implant is described. In the end, the technical specifications of the final solution are listed.
