OBJECTIVES: The primary aim of this study was to evaluate the clinical and radiographic outcomes of 22 one-piece zirconia dental implants placed in 22 patients for the rehabilitation of single-tooth edentulism, with a minimum follow-up of 4.25 years (51 months) and a mean observation period of 82.27 months. At the final follow-up visit, no patient reported foreign body sensation, discomfort, or pain. Moreover, no signs of infection with suppuration or implant mobility were observed. MATERIALS AND METHODS: Marginal bone level (MBL) analysis was performed using standardized radiographs and dedicated software. The mean distance between the implant head and the first detectable bone-to-implant contact was meas-ured on both the mesial and distal sides of each implant. RESULTS: The mean initial MBL was 1.82 ± 0.63 mm, whereas at the final follow-up visit, it was 2.60 ± 0.73 mm. CONCLUSIONS: The data collected in this study, with a mean follow-up of 82.27 months (range 51–120 months), suggest that one-piece zirconia dental implants may represent a viable alternative for supporting single crowns in patients requiring metal-free rehabilitation. However, to better understand the benefits and potential limi-tations of this treatment modality, further well-structured studies with an appropriate study design and long-term follow-up are needed. CLINICAL SIGNIFICANCE: Zirconia dental implants could represent a valid alternative to titanium implants in the medium to long term in cases of single implant-supported rehabilitation.
OBIETTIVI: L’obiettivo principale di questo studio è stato di valutare i risultati clinici e radiografici di 22 impianti dentali monocomponente in zirconia inseriti in 22 pazienti per la riabilitazione di edentulie singole, con un fol-low-up minimo di 4 anni e periodo medio di osservazione di 82 mesi. Durante l’ultima visita di controllo, nessun paziente ha riferito sensazione di corpo estraneo, disagio o dolore. Inoltre, non sono stati riscontrati segni di infezione/suppurazione né mobilità implantare. MATERIALI E METODI: L’analisi dei livelli ossei marginali (MBL) è stata effettuata mediante radiografie standardizzate e un software dedicato. La distanza media tra la testa dell’impianto e il primo punto di contatto con l’osso è stata misurata sui lati mesiale e distale di ciascun impianto. RISULTATI: Il MBL medio iniziale era di 1,82 ± 0,63 mm, mentre alla visita finale risultava di 2,60 ± 0,73 mm. CONCLUSIONI: I dati raccolti in questo studio, con un follow-up medio di 82,27 mesi (range 51-120 mesi), suggeriscono che gli impianti dentali monocomponenti in zirconia potrebbero rappresentare un’alternativa valida per supportare corone singole nei pazienti che necessitano di soluzioni prive di metallo. Tuttavia, per comprendere meglio i benefici e le eventuali limitazioni di questo trattamento, sono necessari studi clinici di qualità metodologica adeguata, con un disegno di studio comparativo e gruppo di controllo nonché un follow-up a lungo termine. SIGNIFICATO CLINICO: Gli impianti dentali in zirconia potrebbero rappresentare una valida alternativa agli impianti in titanio nel medio- lungo periodo in caso di riabilitazione singola implanto-supportata.
