Fiber-reinforced fixed partial dentures: a preliminary retrospective clinical study

Abstract

The aim of this study was to evaluate the clinical performance (retention rate) of fiber-reinforced composite fixed partial dentures (FPDs). Polyethylene fiber (Ribbond®) was used combined with restorative composite during FPDs fabrication. FPDs were placed in thirteen patients in a private clinic. Nineteen FPDS were evaluated. The prosthetic space was filled with only one pontic using extracted teeth (2 cases), acrylic resin teeth (11 cases), or with composite resin (6 cases), combined with Polyethylene fiber. The clinical criterion used was based on retention rate of FPDs. If FPDs were in function in the mouth at the time of examination without previous repair they were classified as Complete Survival (CS) restorations. A classification of Survival with Rebonding (SR) was assigned in the event of an adhesive failure, but after rebonding the FPD still remained under evaluation. Treatment was classified as a Failure (F) if the FPD restoration was lost. The time of evaluation was 41.15 months (±15.13). The FPDs evaluated were retained (CS=94.75%), and no failure was found except for in one situation which required rebonding (SR=5.25%). According to the survival estimation method of Kaplan-Meyer the mean survival time was 42.3 months. At the time of evaluation investigated, polyethylene-reinforced FPDs showed a favorable retention rate in preliminary data.

An evaluation of fracture resistance of interim fixed partial denture fabricated using polymethylmethacrylate and reinforced by different fibres for its optimal placement: an in vitro study

“…9,10 The reinforcing effect of glass fibres was more effective than that of polyethylene fibres, and this was attributed to the difficulty of obtaining good adhesion between ultra-high modulus polyethylene fibres and the resin matrix. 11 The results of the second stage revealed that placing the fibres at the occlusal third of the pontic gave the highest fracture resistance values. It is suggested that reinforcement at the cervical third of the pontic region (area of tension under the occlusal load) showed higher fracture toughness values.…”

“…It is a more conservative treatment option than conventional fixed partial dentures and can be more cost-effective than other types of metal-free tooth replacements. 19,20 A preliminary retrospective clinical study by Piovesan et al25 suggested that polyethylene FRC fixed partial dentures (FPDs) could be a functional and esthetic alternative to replace a lost tooth. Unlu and Belli26 concluded that polyethylene FRC FPDs functioned adequately during a mean clinical follow-up time of 3 years.…”

Puente adhesivo temporal como solución estética en paciente con fisura de labio y paladar.

“…Un estudio clínico retrospectivo llevado a cabo por Piovesan y cols (9) sugirieron que una prótesis parcial fija confeccionada con composite reforzados con fibras de polietileno podría ser una alternativa funcional y estética para reemplazar un diente perdido, no dificulta la posición de la lengua al hablar, ya que mantiene la línea del arco rehabilitado. Unlu y Belli (10) llegaron a la conclusión de que este tipo de prótesis reforzadas con polietileno funcionaron adecuadamente durante un periodo de seguimiento clínico de 3 años.…”
