Repairing mandibular body fractures presents unique challenges not encountered when repairing long bones. Large tooth roots and the presence of the inferior alveolar neurovascular bundle limit safe placement for many types of orthopedic implants. Use of non-invasive fracture repair methods have increasingly become popular and have proven safe and effective at achieving bone healing. Non-invasiv...

Oblique crown-root fracture in the cervical third of the root is a common event following trauma to the anterior region of the mouth. As a result, sound tooth structure coronal to the attachment apparatus may not be available for restorative needs. Invasion of biological width by fracture line presents a clinical challenge in restorative planning. Placing a restoration margin on sound tooth str...

This case report describes the management of an oblique crown-root fracture of maxillary left lateral incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondonal fibres were cut with a surgical blade. A metallic screw type post was ins...

We explored the impact of cusp inclinations on dental fractures in cracked tooth syndrome model and formulated corresponding risk scale. Forty maxillary premolars were randomized into four groups for cusp inclination measurements by digital radiovisiography (RVG). For cracked tooth models, buccal and palatal cusp inclinations were achieved by grinding in groups I (59°-50°), II (64°-55°) and III...

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 reattach...

AIM To report the intentional replantation of a maxillary central incisor with a crown-root fracture. SUMMARY An 11-year-old girl was referred to a paediatric clinic with an extensive crown-root fracture of the maxillary right central incisor (tooth 11) with pulp exposure. Radiographs revealed that tooth 11 had a periapical radiolucent lesion, which suggested pulpal necrosis. The treatment op...

abstract : the crown-root fracture is a common tooth injury which compromises the biological width and need proper endodontic and prosthodontic treatment to achieve acceptable clinical outcome. this case report describes clinical management of crown-root fracture in maxillary central incisors which was successfully treated by forceps eruption with 180˚ rotation to restore the biological width. ...

This case report describes the multidisciplinary management of subgingival horizontal crown-root fracture of an immature permanent maxillary central incisor in a 10-year-old boy. After removal of the fractured fragment, pulpotomy was performed within 48 h from the injury to promote apexogenesis. The tooth was orthodontically extruded until the fracture line was located above the alveolar bone l...

STATEMENT OF PROBLEM The in vitro effectiveness of a uniform circumferential ferrule has been established in the literature; however, the effect of a nonuniform circumferential ferrule height on fracture resistance is unknown. PURPOSE This in vitro study investigated the resistance to static loading of endodontically treated teeth with uniform and nonuniform ferrule configurations. MATERIAL...
