Comparison of implant survival under an overdenture with respect to their number and dimensions

Pokrovna proteza na implantatima mobilna je proteza retinirana razliˇcitim brojem i dimenzijama implantata. Pokrovne proteze retinirane implantatima mobilni su protetski nadomjesci koji se retencijskim elementima sidre na implantatima. One predstavljaju jednu od terapijskih opcija potpune bezubosti. Niz godina potpune proteze predstavljaju konvencionalno rjeˇsenje za terapiju potpune bezubosti. Dijelu pacijenata kojima potpune proteze ne predstavljaju zadovoljavaju´ce rjeˇsenje danas moˇzemo ponuditi alternativu: pokrovne proteze poduprte implantatima. Za donju ˇceljust se, zbog ˇcestog nezadovoljstva pacijenata potpunim protezama, pokrovna proteza poduprta implantatima predlaˇze kao terapija izbora. Kratki implantati pojavili su se na trˇziˇstu kao alternativna opcija kojom bi se smanjila ili eliminirala potreba za vertikalnim augmentacijskim postupcima, koje su ˇcesto povezane s dodatnim troˇskom, duˇzim vremenom terapije i ve´cim rizikom za razvoj komplikacija. Uski implantati imaju prednost naspram standardnih u situacijama smanjenog meziodistalnog prostora i reducirane ˇsirine alveolarnog grebena. To bi moglo pomo´ci starijim pacijentima i medicinski kompromitiranim pacijentima jer bi ukljuˇcivalo manje invazivan kirurˇski postupak. Prednosti terapije potpune bezubosti pokrovnim protezama poduprtim implantatima pove´cana je retencija i stabilnost mobilnih proteza, poboljˇsanje ˇzvaˇcne i fonetske funkcije, poboljˇsanje udobnosti i zadovoljstva pacijenta istim ˇsto rezultira i pove´canom kvalitetom ˇzivota.Overdenture on implants is a mobile prosthesis retained with different number of implants of various dimensions. Implant-retained overdenture is a mobile prosthetic replacement anchored to the implants by retention elements. It represents one of the treatment options for complete edentulousness. For many years, complete dentures have been a convenient solution for the treatment of complete edentulousness. Today, for patients for whom complete dentures are not an option, we can offer overdenture supported by implants as an alternative solution. For the lower jaw, due to the patients’ frequent dissatisfaction with complete dentures, an implant-supported denture is proposed as the therapy of choice. Short implants have appeared on the market as an alternative option to reduce or eliminate the need for vertical augmentation procedures, which are often associated with additional cost, longer therapy, and a higher risk of developing complications. Narrow-diameter implants have an advantage over standard ones in situations of reduced mesiodistal space and reduced alveolar ridge width. This could help elderly patients and medically compromised patients as it would involve a less invasive surgical procedure. The advantages of therapy of complete edentulousness with implant-supported dentures are increased retention and stability of mobile prostheses, improvement of masticatory and phonetic function, improvement of patient comfort and satisfaction with the same, which results in increased quality of life
