1/6. 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 = extraction (Clic here for more details about this article) |
2/6. Cementable implant-supported prosthesis, serial extraction, and serial implant installation: case report.Cement-retained implant-supported prostheses are particularly indicated where access for screw placement is limited or impossible like in posterior locations or where there is limited jaw opening. The patient in this case report suffered from limited jaw opening as a result of a long history of temporomandibular joint ankylosis related to hemophilia. Cement-retained implant-supported prostheses coupled with serial extraction, serial implant installations, and chairside provisional restorations made uneventful treatment possible.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
3/6. osteomyelitis of the mandibular condyle secondary to dental extractions.Although osteomyelitis of the mandibular condyle secondary to dental extraction is scarcely mentioned in the medical and dental literature, we have seen three cases within a two-year period. The first two patients were examined for an eroded condyle three months and 18 months following the extractions. The third patient, who was treated one month after extraction for acute osteomyelitis of the condyle, has done well. All three patients required operations and administration of long-term antibiotics.- - - - - - - - - - ranking = 7keywords = extraction (Clic here for more details about this article) |
4/6. Orthodontic management of ankylosed permanent posterior teeth: a clinical report of three cases.Ankylosed permanent posterior teeth may have a better prognosis than has been generally assumed. Three case reports offer testimony to the effectiveness of surgical luxation (loosening) with forced eruption induced by elastic force. Individual teeth, the occlusion, and the alveolar process may be preserved by early and aggressive treatment. The prognosis may be questionable, but the effect is preferable to premature extraction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/6. Reducing the incidence of unerupted palatally displaced canines by extraction of deciduous canines. The history and application of this procedure with some case reports.The procedure of extracting the deciduous canine to reduce the incidence of the unerupted palatally displaced canine was first described in 1951, and an article solely devoted to the technique appeared in 1959. The procedure then virtually vanished until 1981. A prospective study published in 1988 created the first widespread interest in the method which now appears in major texts. Why the procedure succeeds is uncertain. In the 1950s non-resorption of the deciduous canine was thought to cause palatal deflection of its successor and therefore it appeared appropriate to extract the obstructing deciduous tooth. It has been estimated that the technique should be successful in approximately one in three of all cases in the population aged 10 to 13 years. The earlier the detection the better the prognosis, because the unerupted canine frequently moves more mesially with time. Before the procedure is attempted it is important to discuss possible outcomes with the patient. Three successfully treated cases are illustrated. The first conformed with the guidelines of having an uncrowded maxillary arch and being aged between 10 and 13 years. The second was aged 15 years 2 months at commencement. An unsuccessful surgical exposure of the permanent canines followed by extraction of the deciduous canines was carried out in the third case.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
6/6. Timing of extraction of ankylosed teeth to maximize ridge development.Retaining an ankylosed replanted tooth during jaw growth leads to arrested development of the associated alveolar ridge. As the adjacent teeth erupt and the adjacent alveolar ridge develops, the ankylosed tooth is left in infraocclusion. The severity of the resulting ridge defect depends on the amount of facial growth after ankylosis. The extent of the defect correlates with the length of time an ankylosed tooth is retained during adolescent rapid growth. This case report illustrates the development of an extensive alveolar ridge defect when a replanted tooth became ankylosed and was allowed to remain through an adolescent growth spurt. The change in tooth position is dramatic and reflects the marked difference in ridge development. Clinical guidelines are presented to determine the optimal timing of extraction of ankylosed teeth to maximize alveolar ridge development.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
