1/15. The management of traumatic ankylosis during orthodontics: a case report.Dental ankylosis may be a significant complication in orthodontic clinical practice. This case report describes the management of a malocclusion, complicated by an ankylosed maxillary central incisor, which arose during orthodontic treatment, following an acute traumatic injury. The use of the ankylosed incisor in successfully managing the significant Class II division 1 malocclusion is described.- - - - - - - - - - ranking = 1keywords = occlusion (Clic here for more details about this article) |
2/15. Splinting of traumatized teeth with a new device: TTS (titanium Trauma Splint).Displacement injuries of permanent teeth are an increasing emergency in the dental office. Children and adolescents are particularly prone to dental trauma due to participation in risky activities. Repositioning or replantation with subsequent stabilization by a dental splint is the standard of care for most displaced or avulsed permanent teeth. Non-rigid fixation allowing physiologic tooth mobility has been shown to be desirable for periodontal healing. A flexible splint of short duration appears to reduce the risk of dentoalveolar ankylosis or external replacement resorption. Different splinting techniques are currently recommended for stabilization of repositioned or replanted teeth, including a wire-composite splint, an orthodontic bracket splint or a resin splint. Each splinting option has its specific advantages and shortcomings. This paper describes a new splinting technique which offers improved comfort and handling to the patient and dentist alike.- - - - - - - - - - ranking = 5.9862810151201keywords = dental (Clic here for more details about this article) |
3/15. Moving an ankylosed central incisor using orthodontics, surgery and distraction osteogenesis.When a dentist replants an avulsed tooth, the repair process sometimes results in the cementum of the root and the alveolar bone fusing together, with the replanted tooth becoming ankylosed. When this occurs, the usual process of tooth movement with bone deposition and bone resorption at the periodontium cannot function. If dental ankylosis occurs in the maxillary incisor of a growing child, the ankylosed tooth also cannot move vertically with the subsequent vertical growth of the alveolar process. This results in the ankylosed tooth leaving the plane of occlusion and often becoming esthetically objectionable. This report describes a 12-year-old female with a central incisor that was replanted 5 years earlier, became ankylosed, and left the occlusal plane following subsequent normal vertical growth of the alveolar process. When growth was judged near completion, the tooth was moved back to the occlusal plane using a combination of orthodontics, surgical block osteotomy, and distraction osteogenesis to reposition the tooth at the proper vertical position in the arch. This approach had the advantage of bringing both the incisal edge and the gingival margin of the clinical crown to the proper height in the arch relative to their antimeres. Previous treatment procedures for ankylosed teeth have often involved the extraction of the affected tooth. When this is done, a vertical defect in the alveolar process results that often requires additional bone surgery to reconstruct the vertical height of the alveolar process. If the tooth is then replaced, the replacement tooth must reach from the final occlusal plane to the deficient ridge. This results in an excessively long clinical crown with a gingival height that does not match the adjacent teeth.- - - - - - - - - - ranking = 2.49542700504keywords = dental, occlusion (Clic here for more details about this article) |
4/15. Hypodontia, ankylosis and infraocclusion: report of a case restored with a fibre-reinforced ceromeric bridge.Retained primary molars without permanent successors often undergo progressive infra-occlusion, without predictable exfoliation. Early prophylactic removal, after assessment of root resorption and adjacent periodontal support loss as well as age of onset, is often indicated. This article describes the joint orthodontic-restorative care of such a case and describes an alternative method of restoration using a fibre-reinforced ceromeric bridge. As well as a conservative preparation and good aesthetics, an overlay restoration provided a fully functional occlusion.- - - - - - - - - - ranking = 3keywords = occlusion (Clic here for more details about this article) |

Treatment of a Class I crowded malocclusion with an ankylosed maxillary central incisor.This article describes a Class I crowded malocclusion with an ankylosed maxillary central incisor that was in infraocclusion and labially displaced. Various treatment alternatives are discussed, and the option of extracting the ankylosed tooth followed by space closure with lateral incisor substitution is developed.- - - - - - - - - - ranking = 3keywords = occlusion (Clic here for more details about this article) |
6/15. Management of occlusal and developmental disturbances resulting from an ankylosed maxillary second primary molar: case report.This case report presented the orthodontic management of an ankylosed primary molar. Trauma to the maxillary right second primary molar resulted in the infraocclusion of the affected tooth as well as the mesial tipping of the adjacent first permanent molar and displacement of the permanent successor. After extraction of the ankylosed primary molar, orthodontic therapy was performed to upright the adjacent permanent molar and to gain the lost space of its permanent successor. By the application of orthodontic mechanics, the maxillary right permanent first molar was uprighted and the maxillary right permanent second premolar was brought to its proper position.- - - - - - - - - - ranking = 0.5keywords = occlusion (Clic here for more details about this article) |
7/15. root resorption in dental trauma: 45 cases followed for 5 years.We aimed to: (i) study the prevalence of root resorption after luxation or avulsion injuries on permanent teeth referred to our dental clinic over a 3-year period; (ii) study the relationship between type of injury and resultant type of resorption complication; and (iii) evaluate success of treatment protocols for various resorption complications. We observed 1943 patients with dental trauma, aged between 2 and 26 years, referred to the Accident and Emergency Department of the Dental Clinic, University of Brescia, from 1st September 1997 to 31st December 2001. Of these, 261 permanent teeth had sustained luxation (n = 188) or avulsion (n = 73) injuries. Permanent teeth luxation and avulsion injuries occurred most often in upper incisors (75%) of patients mostly aged 12-21 years, with males more commonly affected than females (68.3% vs. 31.7%). These cases were followed for 5 years, and complications and response to treatment were recorded. root resorption was observed in 45 (17.24%) of these cases. Of the 45 cases with resorption, 9 were associated with luxation injury (20%) while 36 (80%) with avulsion. We distinguished 30 cases of inflammatory root resorption (18 transient and 12 progressive) and 15 cases of ankylosis and osseous replacement. When resorption was recognized, quick and effective treatment could still result in an excellent functional and aesthetic outcome for these teeth.- - - - - - - - - - ranking = 11.97256203024keywords = dental (Clic here for more details about this article) |
8/15. A customized distraction device for alveolar ridge augmentation and alignment of ankylosed teeth.The purpose of this study was to develop an extraosseous, tooth-supported miniature intraoral device that could produce prosthetically driven bone distraction of small atrophic alveolar ridge segments. Extraosseous distraction requires that the distraction device be anchored to a dental implant previously placed into the ridge according to its anatomic axis. A distractor can also correct the position of implants placed in young patients before skeletal growth is completed. Similarly, it allows the alignment of ankylosed teeth not treatable by orthodontics. The device is made of (1) an engine consisting of an orthodontic micrometric screw; (2) a joint between the implant and the engine, ie, the ball attachment/o-ring system; and (3) an anchorage system to the oral cavity provided by an orthodontic appliance and a mini-implant for possible additional support. Surgery involves an osteotomy of the atrophic alveolar ridge segment, incorporating the implant, from the basal bone; afterward the device can be applied and distraction of the segment can be carried out. Distraction was successfully performed in 3 clinical cases: 2 bone-implant segments and 1 bone-ankylosed tooth segment. All cases were clinically uneventful. This mini-device for osteogenic distraction of small atrophic ridge segments can provide for accurate and precise ridge augmentation, as is required for ideal prosthetic rehabilitation.- - - - - - - - - - ranking = 1.99542700504keywords = dental (Clic here for more details about this article) |
9/15. Orthosurgical treatment with lingual orthodontics of an infraoccluded maxillary first molar in an adult.The biological mechanism that leads to a cessation in the normal passive eruption of a tooth is unclear, and there are differing views as to whether ankylosis is involved. When infraocclusion of a permanent molar occurs in the permanent dentition, its effects are seen (1) locally, with exaggerated tipping and relative under-eruption of the adjacent teeth; (2) regionally, with overeruption of the opposing tooth or teeth; and (3) farther afield, with deviation of the dental midline to the affected side. Treatment aimed at eliminating these adverse conditions is warranted, and this might involve the skills of both an orthodontist and an oral surgeon. When the condition occurs in an adult, the changes in facial appearance that will be caused by traditional fixed orthodontic appliances might undermine the patient's willingness to accept treatment. This report describes the successful orthosurgical treatment with lingual orthodontics of an infraoccluded maxillary first molar in an adult. The challenges, treatment alternatives, and technical refinements are emphasized.- - - - - - - - - - ranking = 2.49542700504keywords = dental, occlusion (Clic here for more details about this article) |
10/15. Case report: severe infraocclusion ankylosis occurring in siblings.AIM: This was to report a rare case of strong familiar tendency of ankylosis of maxillary second primary molars. CASE REPORT: Three Caucasian children, male twins of 8.5 years and a sister of 10 years, were diagnosed as having severely infraccluded maxillary second primary molars with underlying second premolars. In all three cases, the early extraction of the infraoccluded molars and an active treatment with cervical extraoral traction allowed the physiologic eruption of second premolars. Follow-up showed that normal vertical relationship and bone height had been obtained. CONCLUSION: early diagnosis, as well as appropriate treatment and careful follow-up are very important in the presence of severe infraocclusion, when the marginal ridge of affected primary teeth is at or below gingival level.- - - - - - - - - - ranking = 2.5keywords = occlusion (Clic here for more details about this article) |
