SUMMARY Knowledge about the stability of fiber posts cemented in widened canal spaces over time is scarce in the literature. Thus, the purpose of this case report was to evaluate the performance of a direct anatomical post in a widened canal space over the course of four years. The present clinical case describes the rehabilitation of a widened canal space using a direct anatomical post (a resin composite combined with a prefabricated glass fiber post) associated with an all-ceramic crown and other restorative procedures. This technique is easy to perform and may solve some of the problems associated with the cementation of a poorly adapted fiber post in a widened canal space.

SUMMARY The following case report describes the three-year follow-up after rehabilitation of a flared root canal using a direct anatomic post (a resin composite combined with a prefabricated glass fiber post) associated with metal-free ceramic restoration. The report presents the clinical protocol for the fabrication of the posts, which provide an intimate fit to the remaining root and mechanical properties similar to those of the dental structure. These posts serve as an alternative to conventional metal cores.

The loss of dental structure caused by endodontic treatment is responsible for a decrease in tooth resistance, which increases susceptibility to fracture. Therefore, it is important that minimally invasive treatments be performed to preserve the dental structure and increase the resistance to fracture of endodontically treated posterior teeth. To evaluate under axial loads, using the finite element method, the stress distribution in endodontically treated molars restored with both transfixed or vertical glass fiber posts (GFP) and resin composite. An endodontically treated molar 3D-model was analyzed using finite element analyses under four different conditions, class II resin composite (G1, control model), vertical glass fiber post (G2), transfixed glass fiber posts (G3) and vertical and transfixed glass fiber posts (G4). Ideal contacts were considered between restoration/resin composite and resin composite/tooth. An axial load (300 N) was applied to the occlusal surface. The resulting tensile stresses were calculated for the enamel and dentin tissue from five different viewports (occlusal, buccal, palatal, mesial and distal views). According to the stress maps, similar stress trends were observed, regardless of the glass fiber post treatment. In addition, for the G1 model (without GFP), a high-stress magnitude can be noticed in the proximal faces of enamel (7.7 to 14 MPa) and dentin (2.1 to 3.3 MPa) tissue. The use of transfixed glass fiber post is not indicated to reduce the stresses, under axial loads, in both enamel and dentin tissue in endodontically treated molar with a class II cavity.

Glass fiber posts and core are increasingly used in order to restore severely damaged endodontically treated teeth and particularly maxillary premolars that are prone to fracture. Their low modulus of elasticity which is similar to that of dentin allows the post to absorb stress and prevent root fracture. In addition, the glass fiber posts provide a natural hue by integrally bonding to the composite, thereby improving the aesthetics without compromising much on the strength. Various factors are involved in the longevity of such treatment option, remaining tooth structure seems to be the most important.

SUMMARY This study aimed to evaluate the cementation and mechanical behavior of flared root canals restored with CAD/CAM milled glass fiber post-and-core systems. Sixty-six endodontically treated human canines with a flared root canal were divided into three different groups according to the type of post: GPF received prefabricated posts; GREL received relined glass fiber posts, and GMILLED received CAD/CAM milled glass fiber posts. Cementation was performed with self-adhesive resin cement. The samples were submitted to x-ray microcomputed tomography analysis for the analysis of voids and gaps. The roots were sectioned and submitted to the push-out bond strength test. The load-to-fracture was evaluated in post-and-core systems. GMILLED presented lower void and lower gap volumes when compared to GPF and GREL. On the load-to-fracture test, GREL presented statistically significant higher values than GMILLED. GPF values had no statistically significant difference from the two other groups. On the push-out bond strength test, GPF presented statistically significant lower values when compared to GREL and GMILLED. The most common failure pattern was between dentin and cement in all groups. CAD/CAM milled glass fiber post-and-core systems presented an enhanced adaptation of glass fiber posts to flared root canal systems. Their results were comparable to relined posts in bond strength, while load-to-fracture-results for GMILLED were lower than those for GPF.

Objective: This case report aims to present the microdontia treatment of tooth 35 through pre-prosthetic orthodontics, followed by re-anatomization with an indirect restoration. Case report: A 21-year-old female patient presented with microdontia in tooth 35, with a distalized and vestibularized crown. In addition, tooth 34 was gyroverted with mesial diastema. Orthodontic mechanics with segmented arch were used to centralize tooth 35 in the alveolar ridge, close the diastema in the mesial of tooth 34, and correct its gyroversion. For lingualization of tooth 35, a first-order fold (in set) was performed, and for mesialization, an open-coil spring was used between teeth 35 and 36. A closed-coil spring was used to delimit the movement of tooth 35 to mesial. The force applied by the open spring for mesialization of tooth 35 was transmitted to tooth 34, through the closed spring, resulting in its mesialization; this, closed the diastema between teeth 33 and 34 and corrected the gyroversion. Subsequently, the coronary preparation was performed with diamond tips 1014 and 3146, and confection of the temporary crown in acrylic resin. For the ceramic system, IPS™ e.max Press was used. The ceramic crown was luting using the adhesive technique, followed by light curing for 40 seconds on each face of the tooth. Conclusion: It can be concluded that the re-anatomization of a small tooth should be the first treatment option. However, pre-prosthetic orthodontic treatment may be necessary.

ABSTRACT Introduction Endodontic restoration becomes a challenging task for the clinician because of severe loss of coronal tooth structure owing to trauma, caries, restorative, and endodontic procedures. The restoration of these teeth requires the use of a post and core as individual units or as abutment supports for fixed or removable restorations in a predictable long-term manner. Aim To compare and assess the compressive bond strength of glass, quartz, and carbon fiber posts restored with porcelainfused- to-metal (PFM) crown. Materials and methods A total of 45 upper central incisor teeth having straight root canals, similar anatomically root segments, and fully developed apices were selected. Teeth were divided into three groups of 15 teeth after endodontic treatment. Group I: Teeth inserted with the prefabricated glass fiber post. Group II: Teeth inserted with the quartz fiber post. Group III: Teeth inserted with carbon fiber post. The posts were placed and core was fabricated using composite restoration followed by PFM crown cementation using adhesive resin. Compressive load required to fracture the tooth was measured using a universal loading machine. The difference between the variables was assessed by one-way analysis of variance, followed by Tukey's post hoc test. Results The compressive strength exhibited by carbon fiber posts was highest with a mean of 668.33 ± 26.397, followed by quartz fiber post (635.80 ± 30.390). Least compressive strength was exhibited by glass fiber post (567.53 ± 26.632). An analysis of variance shows statistically highly significant difference (p < 0.005) among the posts used. Conclusion This study concluded that the carbon fiber posts had higher compressive strength than other quartz, glass fiber posts. Clinical significance Endodontic treatment results in loss of a significant part of the tooth structure. Posts restore these teeth and provide retention.
