I. restorations or class II. mesio-occluso-distal (MOD) indirect overlay restorations with cuspal coverage. Methods Sixty sound maxillary first molars were collected and randomly divided into four groups. In Groups 1 and 2, MOD cavities were prepared and all cusps were reduced by 2 mm, whereas in Group 3 and 4, only a conservative Class I. cavity was prepared. Subsequently, root canal treatment was performed and the mesio-buccal roots were amputated. Groups 1 and 2 were restored with indirect composite overlay, while Groups 3 and 4 received direct composite fillings. After restoration, teeth were embedded as follows: Groups 1 and 3: normal bone level, Groups 2 and 4: furcation involvement. The specimens were submitted to static fracture resistance testing. Fracture thresholds and fracture patterns were measured and evaluated. Results Group 1 had the highest fracture resistance (2311,6 N) among the restored groups and showed statistically significant difference compared to Group 2 (p = 0.038) and Group 4 (p = 0.011). There was no statistically significant difference in terms of fracture resistance between the rest of the groups. In terms of the fracture patterns, Group 3 was characterized by the highest percentage (60%) of mostly favorable fractures, while the rest of the groups showed predominantly unfavorable ones.

Fracture of endodontically treated teeth is a common type of clinical failure. New treatment modalities or perfected versions of existing treatment concepts need to be tested to find a biomimetic solution. A novel method of restoring endodontically treated teeth is presented and compared in vitro with currently accepted restorative methods. Seventy-two extracted and endodontically treated maxillary premolar teeth were divided into six groups (n = 12) depending on restorative technique (Groups 1–6). Group 1: fiber-reinforced composite post (FRC), Group 2: direct layered short FRC post and core, Group 3: short fiber-reinforced obliquely layered composite restoration, Group 4: microhybrid composite restoration, Group 5: fiber-reinforced box, Group 6: control. Specimens were submitted to static fracture resistance test. Fracture thresholds and fracture patterns were evaluated. Group 6 exhibited the highest fracture resistance. Group 2 yielded the highest fracture resistance among the restored groups. The fracture resistance of Group 2 did not differ significantly from Group 6. Groups 1, 3, 4, 5 proved to be significantly different from the control group. There was no statistically significant difference among restored groups. Fracture patterns of tested groups were dominantly non repairable opposed to control groups mostly repairable fractures. Application of direct-layered short FRC post and core in endodontically treated premolars performed statistically similarly in the studied conditions as natural teeth. Therefore, it seems a promising alternative to current endo-restorative solutions. However, further testing is required. © 2016 Informa UK Limited, trading as Taylor & Francis Group}, keywords = {FIBERS; RESTORATION; FRACTURE; fracture toughness; REINFORCEMENT; Biomimetics; biomimetic; Layered composites; Fiber reinforced; Statistically significant difference; Laser tissue interaction; fiber reinforced plastics; Treatment modality; Fiber reinforced composites; Composite restorations; Clinical failure; monoblock; minimal intervention dentistry; Fiber-reinforced composite}, year = {2017}, eissn = {1568-5616}, pages = {1454-1466}, orcid-numbers = {Forster, András/0000-0002-3495-7105; Braunitzer, Gábor/0000-0001-8983-5175; Fráter, Márk Tibor/0000-0002-0365-1613} } @article{MTMT:3069659, title = {In vitro fracture resistance of premolar teeth restored with fibre-reinforced composite posts using a single or a multi-post technique}, url = {https://m2.mtmt.hu/api/publication/3069659}, author = {Fráter, Márk Tibor and Forster, András and Jantyik, A and Braunitzer, Gábor and Nagy, Katalin and Grandini, S}, doi = {10.1111/aej.12150}, journal-iso = {AUST ENDOD J}, journal = {AUSTRALIAN ENDODONTIC JOURNAL}, volume = {43}, unique-id = {3069659}, issn = {1329-1947}, abstract = {The purpose of this study was to evaluate the reinforcing effect of fibre-reinforced composites (FRC) applied in premolar teeth with different techniques and minimally invasive post space preparation.

MOD cavities in molar teeth with different layering techniques. METHODS: One hundred and thirty mandibular third molars were divided into 5 groups (n=26). Except for the control group (intact teeth), in all other groups MOD cavities were prepared. The cavities were restored by either conventional composite with horizontal and oblique layering or by SFRC with horizontal and oblique layering. The specimens were submitted to static fracture toughness test. Fracture thresholds and fracture patterns were evaluated. RESULTS: In general, no statistically significant difference was found in fracture toughness between the study groups,except for horizontally layered conventional composite restorations, which turned out to be significantly weaker than controls. However, SFRC yielded noticeably higher fracture thresholds and only obliquely applied SFRC restorations exhibited favorable fracture patterns above chance level. CONCLUSION: The application of SFRC did not lead to a statistically significant improvement of the fracture toughness of molar teeth with MOD cavities. Still, SFRC applied in oblique increments measurably reduces the chance of unrestorable fractures of molar teeth with class II MOD cavities. SIGNIFICANCE: The restoration of severely weakened molar teeth with the use of SFRC combined with composite might have advantages over conventional composites alone. It was observed from the statistical data, that the application of SFRC with an oblique layering technique yielded not significantly but better fracture thresholds and more favorable fracture patterns than any other studied material/technique combination. Thus further investigations need to be carried out, to investigate the possible positive mechanical effects of SFRC. The application of the horizontal layering technique with conventional composite materials is inferior to the oblique technique and SFRC materials.}, keywords = {Fracture resistance; Dentistry, Oral Surgery & Medicine; Short fibre-reinforced composite}, year = {2014}, eissn = {1879-176X}, pages = {1143-1150}, orcid-numbers = {Fráter, Márk Tibor/0000-0002-0365-1613; Forster, András/0000-0002-3495-7105; Braunitzer, Gábor/0000-0001-8983-5175; Nagy, Katalin/0000-0001-9383-5952} }
