Multi-rooted teeth with extensive dental defects often face challenges in stability and biomechanical failure. High-performance polymer PEEK materials, with properties closer to dentin, show promise i...
A 40-year-old female patient presented with complaints of loss of tooth substance in the posterior mandibular tooth. This case involved the digital design and fabrication of PEEK split post and core t...
The outstanding mechanical properties of PEEK, coupled with the structure of the split post, provide an effective treatment option for weakened multirooted teeth. Simultaneously, the restoration confi...
The aim of this study was to compare the fracture strength and fracture modes of post-cores produced with CAD-CAM from modified polyetheretherketone (PEEK) materials with other custom-produced post-co...
Sixty human mandibular first premolars with equal root sizes were used. The teeth were divided into six groups (...
According to the results of the statistical analysis, a significant difference was found between the groups in terms of mean fracture resistance (...
In our study, zirconia and metal post-core samples showed higher average fracture strength values than PEEK post-cores groups. Repairable failure modes were more common in the zirconia post-cores, whe...
The primary objective of this study is to conduct a comprehensive review of the existing literature that discusses research on post and core restorations, covering aspects such as their composition, m...
Endodontically treated teeth often require 360° ferrule to retain post and core restoration. The literature support on scientific evidence of partial ferrule is limited, hence this study was conducted...
About 54 extracted mandibular 1st premolars were divided into Edelweiss post and core (Group A) and glass fiber post and core (Group B). They were further subdivided into 3 groups each (Partial functi...
The results of this study stated that in the Edelweiss group partial functional ferrule showed higher fracture resistance and in the glass fiber group circumferential ferrule showed higher fracture re...
The type of ferrule was one of the factors that affected the fracture resistance of Edelweiss and Glass fiber post and core group of specimens. The study also concluded that there was a predominant fa...
This study opens multiple avenues and methods in tooth restoration and shows that even a partial functional ferrule is sufficient for restoration, provided the right system is used. How to cite this a...
Rigid post-and-core systems have traditionally been used in the restoration of endodontically treated teeth and are regarded by many as the standard treatment. Flexible materials, including nanocerami...
The purpose of this in vitro study was to compare the fatigue resistance of conventional cast metal and nanoceramic 3-dimensionally (3D) printed resin post-and-core systems with teeth without posts....
Thirty freshly extracted human maxillary premolars were endodontically treated and divided into 3 subgroups (n=10) according to the restorative procedure: cast metal post-and-core (CM), nanoceramic 3D...
The Kruskal-Wallis test indicated statistically significant differences among the cycles needed to reach failure for each of the 3 groups (P<.001). At 1.2 million cycles, there were no CM failures. Th...
All the endodontically treated teeth that received CM survived the 1 200 000 simulated mastication cycles. Both 3DR and 0P specimens fractured at the crown cervical third during mastication simulation...
The aim of this in-vitro study was to compare the amount of material (post and luting agent) and root dentine removed using two methods for removal of endodontic posts....
Human premolar teeth (n=20) were sectioned at the CEJ and fibre reinforced posts were cemented at a length of 10mm following root canal therapy. Teeth were randomly assigned to two study groups. The m...
Both the volume of material removed and the volume of root dentine removed were significantly greater when using diamond burs. (p⟨0.001). The volume of dentine removed using the diamond bur method (me...
Use of a diamond bur to remove fibre reinforced endodontic post removal poses higher risk for root perforation compared to the reaccess kit....
The rising demand for improved aesthetics has driven the utilization of recently introduced aesthetic materials for creating custom post and core restorations. However, information regarding the fract...
Thirty-nine single-rooted human maxillary central incisors were endodontically treated. A standardized post space preparation of 9mm length was performed to all teeth to receive custom-made post and c...
Custom PEEK post and core restorations displayed the least fracture load values at 286.16 ± 67.09 N. In contrast, FRC exhibited the highest average fracture load at 452.60 ± 105.90 N, closely followed...
Within the limitation of this study, both FRC and PICN demonstrated good performance regarding fracture resistance, surpassing that of PEEK....
This in vitro study aims to evaluate the bonding strengths of Polyether ether ketone (PEEK), Polyether ketone (PEKK), Fiber, and Zirconia (ZrO...
Endodontic treatment was performed on 256 intact maxillary central teeth. The test specimens were prepared in four groups according to the types of materials: Glass fiber post-composite core (FB-n:64)...
The bond strength of all test groups decreased after the cycling loading. The bond strength values of zirconia posts showed a statistically significant difference (p < 0.05). The 10 mm length 1.75 mm ...
Within the limitations of this study, one-piece custom-milled Zirconia post-cores appear promising, as they perform well under functional forces, especially in the anterior region. In addition, custom...
The purpose of this in vitro study was to evaluate the internal adaptation, fracture resistance, and fracture pattern of the residual roots and crowns of molars restored with computer-aided design/com...
We selected 32 extracted maxillary first molars and divided them into four groups according to the post-core system: traditional casting titanium (Ti) post-cores (TC group); Ti post-cores fabricated w...
The CCS, TC, and SLM groups exhibited similar internal adaptations across all sections (P < 0.05). The FP group showed good fit with the root canals in the apical and middle sections but a poor fit wi...
The internal adaptation and fracture resistance of the CCS group were similar to those of the TC and SLM groups, and the fracture pattern was mostly restorable, thus meeting the clinical requirements ...
CCS can be used to restore residual roots and crowns of molars and exhibit high efficacy in terms of adaptability and mechanical properties. More studies are required to evaluate the effectiveness of ...
Dental post and core is one of the common procedures performed after endodontic treatment. The aim of this study was to radiographically assess the quality of post and core procedures performed by den...
A retrospective cross-sectional study design was conducted in the College of Dentistry, Imam Abdulrahman Bin Faisal University. A total of 550 periapical radiographs (PAs) of cemented posts were retri...
The study included 502 students and most of them were females (66.5%). Data were obtained from 502 patients (62% females) with fiber posts used in 98.2% of the cases. About 50% of the posts were inser...
The quality of post and core procedures performed by students showed acceptable radiographic quality and were within the recommended standards....
