“…In our study the frequencies of non‐bleeding surfaces in the two groups were 86% (BRS) and 80% (ITI). Earlier studies (Lekholm et al 1986; Cox & Zarb 1987; Leimola‐Virtanen et al 1995) with a higher incidence of plaque accumulation, reported fewer non‐bleeding surfaces.…”

“…There was no significant difference between the two groups with respect to plaque accumulation and mucosal inflammation. The plaque accumulation at 37% and 36% of the implants in the present study can be compared with the varying frequencies reported in the literature: from as high as 40–60% (Lekholm et al 1986; Cox & Zarb 1987; Leimola‐Virtanen et al 1995), to as low as 15% (Adell et al 1986). In the present material, 39–54% of all implants, and 25% of the patients, were totally plaque free, in contrast to corresponding values of 70–75% and 44% reported by Adell et al (1986).…”

In a randomized prospective study, two implant systems were compared in forty consecutive patients treated for mandibular edentulism. The patients were randomly allotted for treatment by the Brånemark two-stage (submerged) system (BRS), or the ITI(R) one-stage (non-submerged) system. In all, 102 Brånemark selftapping implants and 106 ITI hollow screw implants were installed and all patients were treated with full bridges. Biological and prosthodontic parameters, complications, success rates, clinical efficacy, patient satisfaction and resource requirements were evaluated. No differences were found in plaque accumulation, bleeding or complications during the follow-up period. The BRS group showed deeper periimplant sulcus, less attached mucosa, larger bridge-mucosa distance and higher Periotest values. Prosthetic complications were not related to the configuration of the implant systems. After 3 years, the cumulative success rates were 97.9% and 96.8% for the Brånemark and ITI systems, respectively (difference not statistically significant). One implant in the BRS group had failed to osseointegrate at the time of abutment connection, and another was lost after 2 years due to progressive breakdown of bone. In the ITI group, three implants showed progressive bone loss after 1-3 years associated with periimplant infection. All 40 bridges were intact and remained stable throughout the study. There was general patient satisfaction, but about half the Brånemark patients reported difficulty in coping with the surgical procedures. Treatment time was similar for the two systems. It is concluded that both systems meet the current requirements for dental implant systems in the treatment of mandibular edentulism.

“…In spite of this diffusion some aspects have not been deeply investigated, like the mechanical resistance properties of implants and the stability of the connection between implants and prosthesis elements [5][6]. Although it is rather unusual to observe a clinical failure due to the biological reaction of the bone and/or gingival tissues after the installation of a dental implant, some mechanical problems frequently arise, like the fracturing of fixture or other prosthesis components (abutment, the implant-abutment connecting screws) [7][8][9][10][11][12][13]. Another commonly observed problem is represented by the progressive loosening of the screws connecting the implant with the abutment, this event often leads to the fracture of such screws, or even worse, to the fracture of the whole implant [6,14].…”

Frattura Ed Integrità Strutturale

RIASSUNTO. Tra gli impianti dentali quelli endossei sono i più diffusi. Un impianto dentale endosseo si inserisce direttamente nell'osso a cui si fissa per tutta la sua lunghezza. Può avere forme diverse anche se attualmente gli studi scientifici riportano una percentuale di successi nettamente più elevata per gli impianti a vite e a cilindro. Nel corso degli anni sono state sviluppate varie tipologie di impianti dentali permanenti che sono poi stati modificati in base all'esperienza applicativa, alle numerose ricerche e ai test eseguiti ottenendo sostanziali miglioramenti in termini di durabilità, resistenza, migliore osteointegrazione ecc. In questo lavoro sono stati analizzati due tipi di impianti per valutarne la resistenza meccanica. Un impianto concepito e prodotto alla fine degli anni '90 ed ancora in uso in quei pazienti sottoposti ad implantologia fino a circa 10 anni fa, e uno di concezione più recente. Tali impianti sono stati testati a fatica con un sistema appositamente progettato e realizzato in modo da simulare le sollecitazioni reali agenti su di essi durante la masticazione. I risultati di tali test sono stati riportati sotto forma di diagrammi tipo Wohler che forniscono il limite di fatica al di sotto del quale le protesi potrebbero resistere indefinitamente. Lo studio condotto ha voluto anche valutare l'influenza della presenza di un eventuale mezzo corrosivo (NaCl) e l'analisi delle deformazioni e delle superfici di frattura dei campioni. I test condotti hanno evidenziato che il comportamento a fatica non sembra essere influenzato dalla presenza di un ambiente aggressivo quale quello costituito da soluzioni saline. Molto più influente è risultato invece il disegno dell'impianto. L'analisi delle superfici di frattura ha permesso di individuare le aree di innesco della frattura ed i meccanismi di propagazione. In tutti gli impianti esaminati l'innesco si localizza nelle aree in cui l'intensificazione degli sforzi è maggiore. I risultati dell'analisi agli elementi finiti, condotta su uno dei campioni, è in accordo con il tipo di frattura osservato dopo i test. L'analisi SEM delle superfici di frattura, caratterizzate delle tipiche striature di fatica, hanno mostrato inoltre una chiara similitudine tra il tipo di frattura intercorso nei provini testati in laboratorio e quello osservato sugli impianti rimossi da alcuni pazienti perché avevano ceduto dopo un certo periodo di servizio.

“…During the average follow-up period of 7 years (range 1.7e10 years), the implant survival rate of implant-supported mandibular overdentures was 97.5%. Krennmair et al 16 reported a survival rate of 99% during a follow-up period of 1e9 years, 16 whereas Leimola-Virtanen et al 19 reported a rate of 91.5% during a follow-up period of 3e10 years. 19 The results of all these studies support the fact that implant-supported mandibular overdentures have high implant survival rates.…”

Background/purpose: This study investigated the cumulative survival rate of the mandibular implant-supported overdentures in patients treated from 2005 to 2014 at the Chang Gung Memorial Hospital Implant Center. Materials and methods: Mandibular implant-supported overdentures were placed in 61 patients (32 males and 29 females) during the period from 2005 to 2014. These patients were categorized into two groups according to the type of attachment system used, namely, Group A and Group B. Group A included 31 patients (17 males and 14 females who received a total of 124 implants) whose denture was retained by a Hader bar and cast ERA attachments, whereas Group B included 30 patients (15 males and 15 females who received a total of 120 implants) whose denture was retained by a Hader bar and bilateral, extension cantilevers with clips. Results: At the end of the follow-up period, 238 implants remained. Among the failed implants, two implants were in Group A (failure rate 2/124 Z 1.6%), whereas four implants were in Group B (failure rate 4/120 Z 3.3%). Fifty percent (3/6) of the failed implants were placed in the distal anterior mandible and 50% (3/6) were placed in the middle anterior mandible. The condition of the opposing arch was also analyzed in relation to the survival rate. The failure rate among patients with maxillary complete dentures was only 1.6%, whereas those wearing maxillary removable partial dentures had the highest implant failure rate (3/61 Z 4.9%).Journal of Dental Sciences (2015) xx, 1e6Conclusion: Our results indicate that implant-supported overdentures provide a reliable and effective alternative to conventional complete mandibular dentures. Overdentures with Hader bars and bilateral, cast ERA attachments resulted in fewer prosthetic complications.
