Survival rate, load to fracture, and finite element analysis of incisors and canines restored with ceramic veneers having varied preparation design

Purpose: To evaluate the survival rate, success rate, load to fracture, and finite element analysis (FEA) of maxillary central incisors and canines restored using ceramic veneers and varying preparation designs.Methods and Materials: Thirty human maxillary central incisors and 30 canines were allocated to the following four groups (n=15) based on the preparation design and type of tooth: Gr1 = central incisor with a conservative preparation; Gr2 = central incisor with a conventional preparation with palatal chamfer; Gr3 = canine with a conservative preparation; Gr4 = canine with a conventional preparation with palatal chamfer. Ceramic veneers (lithium disilicate) were fabricated and adhesively cemented (Variolink Veneer). The specimens were subjected to 4 x 106 mechanical cycles and evaluated at every 500,000 cycles to detect failures. Specimens that survived were subjected to a load to fracture test. Bidimensional models were modeled (Rhinoceros 4.0) and evaluated (MSC.Patrans 2005r2 and MSC.Marc 2005r2) on the basis of their maximum principal stress (MPS) values. Survival rate values were analyzed using the Kaplan-Meier test (alpha = 0.05) and load to fracture values were analyzed using the Student t-test (alpha = 0.05).Results: All groups showed 100% survival rates. The Student t-test did not show any difference between the groups for load to fracture. FEA showed higher MPS values in the specimens restored using veneers with conventional preparation design with palatal chamfer.Conclusion: Preparation design did not affect the fracture load of canines and central incisors, but the veneers with conventional preparation design with palatal chamfer exhibited a tendency to generate higher MPS values.

The essential role of annexin A1 mimetic peptide in the skin allograft survival

Immunosuppressive drugs have a critical role in inhibiting tissue damage and allograft rejection.Studies have demonstrated the anti-infl ammatory effects of the annexin A1 (AnxA1) in the regulationof transmigration and apoptosis of leucocytes. In the present study, an experimental skin allograftmodel was used to evaluate a potential protective effect of AnxA1 in transplantation survival. Micewere used for the skin allograft model and pharmacological treatments were carried out using eitherthe AnxA1 mimetic peptide Ac2-26, with or without cyclosporine A (CsA), starting 3 days beforesurgery until rejection. Graft survival, skin histopathology, leucocyte transmigration and expressionof AnxA1 and AnxA5 post-transplantation were analysed. Pharmacological treatment with Ac2-26increased skin allograft survival related with inhibition of neutrophil transmigration and inductionof apoptos is, thereby reducing the tissue damage compared with control animals. Moreover, AnxA1and AnxA5 expression increased after Ac2-26 treatment in neutrophils. Interestingly, thecombination of Ac2-26 and cyclosporine A showed similar survival of transplants when compared withthe cyclosporine A group, which could be attributed to a synergistic effect of both drugs. Investigationsin vitro revealed that cyclosporine A inhibited extracellular-signal-regulated kinase (ERK) phosphory-lation induced by Ac2-26 in neutrophils. Overall, the results suggest that AnxA1 has an essential role inaugmenting the survival of skin allograft, mainly owing to inhibition of neutrophil transmigration andenhancement of apoptosis. This effect may lead to the development of new therapeutic approachesrelevant to transplant rejection.

Survival rate of osseointegrated implants in atrophic maxillae grafted with calvarial bone: a retrospective study

The aim of this study was to evaluate the clinical survival rate of osseointegrated implants placed in the atrophic maxilla that has been reconstructed by means of autogenous bone grafts harvested from a cranial calvarial site. Further, we sought to analyse the level of pen-implant bone after prosthetic rehabilitation and to determine subjective patient satisfaction with the treatment performed. This study conformed to the STROBE guidelines regarding retrospective studies. Twenty-five patients who had received osseointegrated implants with late loading in the reconstructed atrophic maxilla were included in the study. The survival rate and level of pen-implant bone loss were evaluated. A questionnaire related to the surgical and prosthetic procedures was completed. The observed implant survival rate was 92.35%. The mean bone loss recorded was 1.76 mm in the maxilla and 1.54 mm in the mandible. The results of the questionnaire indicated a high level of patient satisfaction, little surgical discomfort, and that the patients would recommend the procedure and would undergo the treatment again. From the results obtained, it is concluded that the cranial calvarial site is an excellent donor area; calvarial grafts provided stability and maintenance of bone volume over the course of up to 11 years.
