Abstract

Jedino djelomična proteza koja je planirana i izrađena uz poštivanje tehničko-
-mehaničkih i bioloških kriterija uklopit će se u usnu šupljinu i osigurati ravnomjernu
raspodjelu opterećenja na mukogingivna tkiva i na parodont uporišnih zuba. Samo na
taj način izrađena proteza omogućuje harmoničnu funkciju žvačnoga sustava (1).
Prema tome, biostatički problem djelomične proteze nastaje uglavnom zbog
razlike između stupnja pomičnosti preostalih zuba i stupnja pomičnosti protezne baze
na rezilijentnom čeljusnom tkivu (2).
Postupci planiranja i izrade djelomičnih proteza moraju se provesti tako da se
uvijek ima na umu prag biološke izdržljivosti tkiva na koja će se opterećenje prenositi.
Meka i koštana tkiva ležišta djelomične proteze ne smiju se preopterećivati tako da se
prekorači biološki prag podnošljivosti, koji jako varira od pojedinca do pojedinca, a
ovisan je o otporu tih tkiva (1).
Teleskopske veze nadmašuju sva ostala sredstva veze, prije svega svojom
mehaničkom robusnošću. Sekundarnim povezivanjem u blok stabiliziraju se uporišni
zubi, a skidanjem proteze omogućeno je održavanje besprijekorne higijene.
Navedenim prednostima treba dodati još i zadovoljavajuću funkcijsku trajnost
nadomjestka, koja je veća od bilo kojega drugog sredstva veze.
Najveća zapreka široj primjeni teleskopskih i konusnih kruna leži u tome što
zahtijevaju veoma visok standard stručnoga znanja i manualne spretnosti stomatologa
i zubnoga tehničara. Potreba opsežnoga brušenja uporišnih zuba predstavlja
manjkavost (1).

Abstract (english)

Exclusively the partial dentures that have been planned and made in
accordance with technical, mechanical and biological criteria will fit into the oral
cavity and ensure a uniform distribution of burden on mucogingival tissues and the
periodontium of the pivot teeth. Only dentures made in this way enable a
harmonious functioning of masticatory system (1).
Consequently, biostatic problems with partial dentures originate primarily as
a result of the difference between the level of mobility of the remaining teeth and
the level of mobility of the denture base on the resilient maxillary tissue (2).
The processes of planning and manufacturing of partial dentures need to be
implemented primarily keeping in mind the threshold of biological resilience of the
tissue to which the burden will be transferred. Soft and osseous tissues of the base
of the partial dentures must not be overburdened to pass the biological threshold of
tolerability that greatly varies amongst different individuals and it depends on the
resistivity of these tissues (1).
Telescopic retainers exceed all the other types of retainers, primarily due to
their mechanical robustness. Pivot teeth are stabilised through a secondary binding
into a block, whilst the removal of the denture enables the maintenance of impeccable hygiene. Moreover, it is important to highlight the satisfactory
functional durability of the prosthesis that exceeds any other type of retainer.
The main obstacle to a wider use of telescopic and conus crowns is the
requirement for compliance with an extremely high standard of professional
knowledge and manual dexterity of both the stomatologist and the dental technician.
The requirement for a comprehensive drilling of pivot teeth is a drawback (1).
