Objectives: This study aimed to investigate the fracture strength of a novel-designed Zirconia crown before and after access opening, and to evaluate the mode of fracture and the time needed for initial penetration through the crown. Methods: This study involved the design and testing of 60 zirconia crowns, divided into three groups (20 crowns each) to compare different structural designs. Group 1 (Control) used a conventional full zirconia crown. Group 2 (Novel Design) featured a zirconia crown with an impermeable ceramic-filled opening.

Dental trauma frequently results in coronal fractures of the front teeth. Root canal therapy followed by reattaching the fractured segment with fiber post reinforcement is a viable alternative in cases of complex fractures where the fractured segment is present and there is close approximation of the segment to the intact tooth. Reattaching a fractured piece is a quicker, less involved process that offers immediate relief, better aesthetics, and function restoration.

A trauma with accompanying fracture of anterior teeth is an agonizing experience for an individual requiring immediate attention, not only because of the physical disfigurement but also because of the psychological impact on the patient.

Crown fractures are a common type of dental injuries and very frequently occurred on maxillary anterior teeth, area of requiring a rapid aesthetic recovery. Crown fragment reattachment is a simple and conservative method to restore the fractured teeth. The technique promotes esthetic outcomes as utilizing natural contour, shade, surface texture of teeth and gives mechanical similarity in terms of wear-resistance. Also it gives emotional positive responses to patients and requires less of chair time and costs. This case report presents two cases of crown fragment reattachments on maxillrary ant

Coronal fractures of permanent dentition are the most frequent type of dental injury. Fractured anterior teeth are usually treated with conventional post and core and crown techniques, after being treated endodontically. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols. Fiber-reinforced post makes the reattachment of the crown esthetically possible with minimal preparation and reduces the possibility of tooth fracture during function.

Trauma may result in craze lines on the enamel surface, one or more fractured cusps of posterior teeth, cracked tooth syndrome, splitting of posterior teeth, and vertical fracture of root. Out of these, management of some fractures is of great challenge and such teeth are generally recommended for extraction. Literature search reveals attempts to manage such fractures by full cast crown, orthodontic wires, and so forth, in which consideration was given to extracoronal splinting only.

The purpose of this study was to determine and compare the shear force (N) required to fracture or dislodge an all-ceramic zirconia-based crown using different luting cement with those of polycarbonate crown and strip crown for the primary anterior teeth in vitro. Study design: Four groups of esthetic restoration for primary anterior teeth were tested for fracture strength: 1) Fifteen all-ceramic zirconia-based crowns cemented with glass ionomer cement, 2) Fifteen all-ceramic zirconia-based crowns bonded with a self-adhesive resin cement, 3) Fifteen polycarbonate crowns cemented with a polymer

The teeth that are most frequently affected by the traumatic injuries are maxillary incisors that results in complicated crown or crown root fractures involving dental pulp. Currently biological approaches are taken into consideration for the management of such injuries in order to restore aesthetics and function on the same day to prevent the social and psychological stress of the patient. This case report is about reattachment of the fractured fragment as a conservative approach for the management of complicated crown fracture using Glass Fiber-Reinforced Adhesive splint in a maxillary centr

Background/Aim. Fracture toughness determines functional crown strenght and prevents damages on ceramics during mastication. There is a lack of relevant literature data about fracture toughness of crowns made by feather-edge preparation. Mechanical testing of ceramic samples is supposed to show if feather-edge tooth preparation is a successful method for making ceramic crowns without any risk of reduction of their mechanical properties. This research was done to establish effects of feather-edge tooth preparation on fracture toughness of single zirconia ceramic crowns. Methods. The research wa

Crown root fractures of anterior teeth are complex dental injuries that present unique challenges due to the involvement of both the crown and root structures. These fractures often lead to concomitant periodontal injury, which can complicate the treatment outcome. Additionally, anterior fractures pose aesthetic and psychological concerns for the patient. Reattachment or restorative repair of fractures involving the coronal third of the root are notoriously prone to failure due to their proximity to the oral cavity leading to difficulty in isolation and bacterial contamination.

Crown-root fractures are one of the most challenging trauma cases to treat. Reattachment of tooth fragment to a fractured tooth being a simple procedure conserves the tooth structure, maintains the natural esthetics value and is thus considered as a favorable treatment option.

Complicated crown-root fractures of maxillary incisors are a relatively common occurrence in cases of trauma to the facial region. Patients with such fractures are in acute pain and usually require emergency care on their first clinical visit. Pain management and restoration of function, esthetics, and phonetics should be the prime objective in handling such patients. The reattachment of fractured tooth fragments is a relatively simple procedure that provides natural esthetics and conservation of tooth structure.

This report describes three cases of complicated crown fractures treated with partial pulpotomy using BioAggregate. Three maxillary permanent central incisors with complicated crown fracture were treated by partial pulpotomy using BioAggregate and reviewed clinically and radiographically for 24 months. Throughout this period, there was no spontaneous pain, periapical radiolucency, and coronal discoloration; the pulp was observed to be vital. Based on these findings, it was concluded that BioAggregate can be used in partial pulpotomy treatment of complicated crown fracture.
