1/21. A case report of a vital replanted tooth with unfavourable extra-alveolar condition: a 10-year follow-up.This case report describes the survival of a maxillary left central incisor after an avulsion injury under unfavourable extra-alveolar condition, when the patient was 9 years old. At subsequent clinical follow-ups, the tooth maintained vitality 10 years after the injury. There was sign of gradual obliteration of the root canal space. Concomitantly, the replanted tooth manifested typical characteristics of ankylosis with minimally detectable resorption complication.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/21. Treatment of an "ankylosed" upper central incisor in the mixed dentition.A ten-year-old boy presented with an unerupted upper right central incisor (UR1). An OPG radiograph showed a supernumerary tooth lying over its crown, preventing its eruption. Standard orthodontic treatment involving removal of the supernumerary tooth, attaching a gold chain to the UR1 and treatment with fixed orthodontic appliances failed to bring the tooth down, until it was found that tough fibrous gingival tissue entwined in the gold chain had "ankylosed" the tooth. Once this tissue had been removed and the wound packed open, the tooth was brought down successfully into occlusion.- - - - - - - - - - ranking = 0.83333333333333keywords = tooth (Clic here for more details about this article) |
3/21. Decoronation of an ankylosed tooth for preservation of alveolar bone prior to implant placement.A 12-year-old patient sustained avulsions of both permanent maxillary central incisors. Subsequently, both teeth developed replacement resorption. The left incisor was extracted alio loco. The right incisor was treated by decoronation (removal of crown and pulp, but preservation of the root substance). Comparison of both sites demonstrated complete preservation of the height and width of the alveolar bone at the decoronation site, whereas the tooth extraction site showed considerable bone loss. In addition, some vertical bone apposition was found on top of the decoronated root. Decoronation is a simple and safe surgical procedure for preservation of alveolar bone prior to implant placement. It must be considered as a treatment option for teeth affected by replacement resorption if tooth transplantation is not feasible.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
4/21. Long-term occlusal guidance of a severely intoxicated patient with yusho (PCB poisoning): a case report.The peculiar dentoorofacial characteristics and 12 years of interdisciplinary management of a patient who was severely intoxicated with the man-made chemical polychlorinated biphenyls (PCBs) are described in this case report. Cephalometric measurements showed that the SNA and SNB angles were reduced but that the developments in height and skeletal maturity were in normal ranges. Gingival hyperpigmentation that was caused by high blood PCB concentration was extremely slow to fade. A cystic mass, diffused trabeculae, and irregular calcification, which were shown on the radiograph and which were caused by high blood levels of PCB, changed gradually. However, the patient had periodontal disease because of horizontal alveolar bone resorption and a deep periodontal pocket, despite good plaque control. After the PCB poisoning the tooth roots were hypoplastic and dilacerated. One root was extracted because of chronic periodontitis. Some teeth were impacted, malposed, or ankylosed.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
5/21. Primary impaction of primary teeth: a review and report of three cases.Primary impaction of primary teeth is rare. Only ten cases have been found in the world literature. It affects almost always second molars and the finding is usually occasional. Three cases of this abnormality, two of the upper jaw and one of the mandible, are presented. The analysis of the characteristics of these cases and the cases in the literature, suggests that ankylosis has probably a leading role in the etiopathogenesis. The following criteria for a correct diagnosis is presented: 1) deep retention into the bone; 2) absence of caries, restorations and resorptions; 3) frequent passing of the corresponding permanent premolar; and possible retention of the corresponding adjacent tooth. More attention is recommended in the study of the lesion for the future.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
6/21. Treatment of the ankylosed mandibular permanent first molar: a case study.The treatment of ankylosed teeth has been reported. While the diagnosis of the condition can be readily made, the etiology remains unknown. Treatment of these teeth is aimed at preventing malocclusions and periodontal defects from developing. Once diagnosed, these teeth require careful evaluation and prompt treatment. Delaying treatment nearly always results in a less favorable outcome. In the case presented, it was thought best to attempt luxation rather than to extract the mandibular first molar to overcome the ankylosis. This reasoning was based on the fact that there was adequate space for the first molar to erupt into and the maxillary first molar had not over-erupted. Selection of the best mode of treatment will depend upon many factors, including space available for the eruption of the involved tooth, inclination of the tooth, stage of development of the dental arches and overall health of the involved tooth.- - - - - - - - - - ranking = 0.5keywords = tooth (Clic here for more details about this article) |
7/21. ankylosis of permanent teeth: a case report and literature review.A case report describing an ankylosed permanent maxillary canine which was brought into the arch by a combination of surgery and orthodontics is used as a basis to review the literature concerning many aspects of the management of ankylosed permanent teeth. The literature indicates surgical luxation is a two edged sword, that is, it may cause ankylosis if used with surgical exposures but it can also be the only means of treating ankylosis. The treatment of the canine which is the subject of this case report resulted in damage to the tooth. Vanarsdall's recent contributions in this field are detailed.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
8/21. Ankylosed teeth as abutments for maxillary protraction: a case report.It has been recognized that using the maxillary teeth to deliver extraoral force to the maxilla not only results in sutural remodeling but also periodontal remodeling and tooth movement. In patients with severe maxillomandibular malrelationships, the potential for tooth movement often limits the amount and duration of extraoral force and, consequently, affects the success of treatment. This case report describes a technique to intentionally ankylose deciduous teeth in a patient with severe maxillary retrusion. The ankylosed teeth were used as abutments to deliver an anteriorly directed intermittent extraoral force. After 12 months of treatment, the anterior crossbite was nearly corrected. At that point the ankylosed teeth loosened because of root resorption and the treatment was terminated. Cephalometric superimposition demonstrated that the occlusal correction was the result of anterior maxillary movement with little mandibular growth and no movement of the ankylosed teeth. The results suggest that intentionally ankylosed teeth may be used as abutments for extraoral traction in patients with a severe disturbance in maxillary growth.- - - - - - - - - - ranking = 0.33333333333333keywords = tooth (Clic here for more details about this article) |
9/21. Early hypercementosis and arrested dental eruption: heritable multiple ankylodontia.This study describes arrested posterior permanent tooth eruption in association with hypercementosis, reduction of the periodontal ligamental space, and bony ankylosis. The severe dental malocclusion occurred in four members of the same family and it appears to have an autosomal dominant mode of inheritance.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
10/21. ankylosis of maxillary permanent first molar.A case of ankylosis of the maxillary right first permanent molar has been described. For 19 months, no change had been observed clinically or radiographically in the development of the tooth. A diagnosis of ankylosis of the unerupted tooth was made. Instead of extracting the tooth, the ankylosed tooth was rocked in the bone to break the point of ankylosis. The tooth subsequently erupted and satisfactory functional results were obtained. It is suggested that this procedure should be attempted in other cases of ankylosis of permanent teeth.- - - - - - - - - - ranking = 0.83333333333333keywords = tooth (Clic here for more details about this article) |
