Abstract

Resorpcije alveolarnog grebena nastale nakon vađenja zuba predstavljaju problem kod planiranja implantološke terapije, a nadomještanje kosti često komplicira i produžuje trajanje terapije. Prilikom ugradnje dentalnih implantata poželjno je ostvariti dobru primarnu stabilnost samog implantata, koja izravno ovisi o površini kontakta kosti i implantata. Upotrebom novih tehnika preparacije s oseodenzificirajućim svrdlima omogućeno je kondenziranje i zbijanje kosti, čime dolazi do povećanja čvrstoće i sabijanja kosti unutar ležišta za implantat, naročito u molarnoj regiji gornje čeljusti. Navedenu tehniku moguće je koristiti u zahtjevnim situacijama
kao što su: smanjena vertikalna dimenzija, tj. transkrestalna (zatvorena) tehnika podizanja dna maksilarnog sinusa, u kojoj se dno sinusa odiže koristeći samo svrdla ili u situacijama kada je zbog smanjene širine grebena potrebno širenje grebena u kombinaciji s piezokirurgijom. Pod pretpostavkom da će prilikom preparacije doći do kondenziranja kosti u bočnim stijenkama i apikalnoj stijenci ležišta, ovom tehnikom i dizajnom svrdla za preparaciju ležišta u situacijama smanjenog koštanog volumena moguće je odmah ugraditi dentalni implantat. U ovim prikazima slučajeva demonstrira se uspješan rezultat minimalno invazivnog načina prepariranja ležišta za implantat s ciljem maksimalnog očuvanja alveolarne kosti.

Abstract (english)

Resorption of the alveolar ridge that occurs most commonly after tooth extraction represents a problem in planning implant therapy, and bone replacement often complicates and prolongs the duration of therapy. When inserting dental implants, it is desirable to achieve good primary stability of the implant itself, which directly depends on the contact surface between bone and implant. The use of new preparation techniques with osseodensification drills enables condensing and compacting of the bone, which leads to an increase in strength and compression of the bone within the implant bed, especially in the molar region of the upper jaw. This technique can be used in demanding situations such as reduced vertical dimension, i.e.,
transcrestal (closed) sinus floor elevation technique, in which the sinus floor is raised using only drills, or in situations where ridge expansion is required in combination with piezoelectric surgery due to the reduced ridge width. Assuming that bone condensation will occur in the lateral and apical walls of the implant bed during preparation, this technique and drill design
for preparing the implant bed in situations of reduced bone volume make it possible to immediately insert a dental implant. These case studies demonstrate the successful result of a minimally invasive method of preparing the implant bed with the aim of maximum preservation of alveolar bone.
