Fracture of anterior teeth due to trauma is the most frequent type of injury affecting permanent dentition. Despite the availability of a wide range of restorative materials, none could match the properties of natural tooth structure like translucency, wear resistance, and color stability. Hence fragment re-attachment is an excellent method of restoring fractured teeth. When the fractured fragm...

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...

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...

In the present case reports, it was aimed to present the treatment of 2 non-complicated crown fracture trauma cases using reattachment technique. In the first case 12-years-old patient was applied to our clinic due to crown fracture. In the clinic examination the tooth’s mobility was within the normal limits and tooth was not tender to percussion. There was also cold-sensitivity due to the expo...

Spiral bevel gears occupy several advantages such as high contact ratio, strong carrying capacity, and smooth operation, which become one of the most widely used components in high-speed stage of the aeronautical transmission system. Its dynamic characteristics are addressed by many scholars. However, spiral bevel gears, especially tooth fracture occurrence and monitoring, are not to be investi...

OBJECTIVE The objective of this study was to evaluate the load-fatigue performance of posterior ceramic onlay restorations relative to two variables: preparation design (with or without buccal veneers); and the existing amount of tooth structure (non-worn tooth, worn tooth). METHODS Sixty extracted third molars were divided into five groups. One group received a mesial-occlusal-distal (MOD) g...

Instead of extraction this case report presents an alternative treatment option for a maxillary incisor with a vertical root fracture (VRF) causing pain in a 78-year-old patient. After retreatment of the existing root canal filling the tooth was stabilized with a dentine adhesive and a composite restoration. Then the tooth was extracted, the VRF gap enlarged with a small diamond bur and the exi...

The effect of width of the restoration, tooth position, and amalgam type on the fracture of the margins of 13- to 14-year-old, high-copper, amalgam restorations was evaluated. The evaluation assessed 193 photographs of restorations by use of ridit analysis and a rank-ordering test. The results indicated that the width of the restoration was the predominant factor and that tooth position and the...

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...
