Overdenture su denti naturali. Analisi dei vantaggi clinici
No full textHybrid prosthesis supported by natural teeth (overdenture) is widely used in clinical practice and should be executed whenever the clinical conditions suggest it. Through a critical review of the literature, the anatomical, functional, psychological and clinical advantages are emphasized. Among the first ones, the prophylaxis of residual anatomical components, due to the limitation of bone resorption, and the preservation of sensorial proprioception are relevant. Important advantages are also represented by a better crown-root ratio of residual teeth supporting overdenture, with the consequent improvement of the longitudinal prognosis of such teeth. The greater retention and stability of overdenture in comparison with complete denture greatly improve the masticatory efficacy. The psychological advantages resulting from the dental anchorage, which allows the patient to be more confident in social life, are also relevant. Finally, when the dental support is lost, converting overdenture into complete denture is simple and quick, and makes easier the longitudinal clinical maintenance of the denture

No full textAim. The purpose of this paper was to review different endodontic irrigants use in endodontics. Background. Many areas inside the canals are inaccessible to mechanical instrumentation, the presence of lateral and accessory canals makes root canal preparation even more difficult. The complete smear layer removal from the root canals depends consequently on both the irrigant solutions and the instrumentation phase. Review consults. Irrigants play a very important role in disinfecting the root canals thus the use of specific solutions has been performed in conjunction with mechanical instrumentation for many years. Combination of several irrigants can increase the capability to penetrate inside the tubules improving the final effect against resistant germs like Enterococcus faecalis that plays an important role in the failure of root canal treatment. Conclusion. The ideal irrigant solution should be microbiocidal, dissolve organic tissues and provide a mechanical flushing action without damaging the periradicular tissues in case of extrusion into the periodontium. Clinical significance. Future research on irrigants needs to focus on finding a single unique solutions that should have all those properties
Tooth implant-supported removable denture: a systemaric review
No full textPurpose: The aim of this systematic review is to verify whether tooth-implant supported removable dentures (TISRD) can really be proposed to patients as a successful alternative to traditional prosthetic therapy.
Methods: This systematic review was carried out following the PRISMA guidelines and the studies were selected by PubMed and Scopus. The keywords were “tooth-implant connection,” “removable denture,” “removable dental prosthesis,” “tooth and implant supported removable dentures,” “partial dentures,” and “overdenture.” The outcomes sought in the potentially eligible studies were the survival rate of TISRD, the patient satisfaction, presence of biological and technical complications; furthermore the bias risk assessment was performed.
Results: Out of the 3108 citations found, 19 studies met the inclusion criteria. In the included studies the enrolled participants were 615, the implant abutments were 1118 and the residual teeth were 601. The behaviour of abutments was examined for a time range between 6 and 180 months. The survival rate of TISRD ranged between 91.82 and 100%; as for complications, none of the authors reported intrusion and the most frequent biologi.
Clinical significance: The tooth-implant connection seems to be an alternative and beneficial treatment for the rehabilitation of partially edentulous patients, however the evidence remains slight and unclear due to the shortage of controlled and randomized clinical trials. Therefore, further studies with a higher level of evidence and more representative samples are need
Osseotite caricati a due mesi nei settori posteriori del mascellare superiore: controllo a 2 anni di due casi clinici
No full textAim Acid etched surface implants determine high clinical success rates, but little
information is available about early loading in the posterior region of the
maxilla, area at risk of failure. The aim of this work is to present two case reports
of oral rehabilitation through acid etched surface implants (Osseotite, Implant
Innovations - 3i, West Palm Beach, FL) loaded two months after insertion in the
posterior maxilla. Materials and methods The success of Osseotite
implants was assessed 12 and 24 months after prosthetic loading according to
Albrektsson et al. criteria (1986). Results No clinical or radiographic signs of
implant failure were observed during the two years follow-up. Conclusions
The Osseotite implants placed in the posterior maxilla seemed to support a functional
loading applied two months after insertion
