1/76. Treatment of an impacted dilacerated maxillary central incisor.Impacted incisor With Dilaceration refers to a dental deformity characterized by an angulation between crown and root causing noneruption of the incisor. Surgical extraction used to be the first choice in treating the severely dilacerated incisor. In this article, a horizontally impacted and dilacerated maxillary central incisor was diagnosed radiographically. By combining two stages of the crown exposure surgery with light force orthodontic traction, the impacted dilacerated incisor was successfully moved into proper position. However, long-term monitoring of the stability and periodontal health is critical after orthodontic traction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/76. Unerupted second primary mandibular molar positioned inferior to the second premolar: case report.This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary molar and the supernumerary tooth. Periodic examination was indicated for follow-up.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/76. Glanzmann's thrombasthenia. Report of two oral surgical cases using a new microfibrillar collagen preparation and EACA for hemostasis.Glanzmann's thromboasthenia is a rare congenital platelet disorder characterized by a prolonged bleeding time, a qualitative platelet defect, and severe hemorrhagic episodes. patients with this disorder have been managed by administration of blood and blood components (most recently, platelet-rich plasma and platelet concentrates) to control hemorrhage resulting from trauma or surgical procedures. The two case reports presented here illustrate the use of a local hemostatic agent (microfibrillar bovine collagen, Avitene) and a systemic fibrinolytic inhibitor (epsilon aminocaproic acid, Amicar) to control postoperative hemorrhage secondary to elective extraction of teeth. The clinical results demonstrate excellent postoperative hemostasis and support recent in vitro observation of platelet adherence to the collagen preparation. This provides an alternate therapeutic modality in the management of patients with Glanzmann's disease and possibly other disorders of platelet function.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/76. A case of supernumerary teeth in the premaxilla, maxillary cuspid, and mandibular premolar regions.A case of several developing supernumerary teeth is reported. A seven-year-old African-American boy presented with retained primary maxillary central incisors, two impacted mesiodens, and unerupted permanent maxillary central incisors. A dentigerous cyst was removed at the time of surgical removal of the mesiodens. Approximately fourteen months post-extraction, a new panoramic radiograph showed the presence of six previously unidentified developing and unerupted supernumerary teeth, one on each of the maxillary cuspid areas and two on the mandibular premolar regions bilaterally. Practitioners should be aware that supernumerary teeth may develop late. Thus, periodic reevaluation with appropriate radiographs is indicated, especially in patients who have presented with supernumerary teeth.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/76. Immediate placement of implants in extraction sites of maxillary impacted canines.BACKGROUND: Treatment of asymptomatic impacted maxillary canines in adults is inevitable when primary canine becomes lost through extraction or exfoliation or when the impacted tooth becomes symptomatic. Treatment alternatives include an orthodontic procedure to bring the unerupted tooth to the dental arch or prosthetic replacement of the missing tooth. The authors describe an alternative treatment that involves immediate placement of implants into extraction sockets of the teeth. CASE DESCRIPTION: A patient with bilateral palatally impacted upper canines chose to have the unerupted teeth removed and replaced with implants and crowns. Two hydroxyapatite cylindrical implants were inserted through the alveolar ridge into the extraction sites. The unfilled areas in the extraction sites, around the dental implants, were packed and covered with demineralized freeze-dried bone allograft in conjunction with a collagen membrane barrier. Six months after implantation, computed tomography revealed complete osseous fill of the extraction defects and no bone loss around the implants. The implants were uncovered, and porcelain-fused-to-metal restorations were fabricated and placed. CLINICAL IMPLICATIONS: This treatment modality avoids the need for conventional preparation of teeth as part of prosthetic reconstruction or prolonged orthodontic treatment aimed at bringing the impacted canine to the dental arch. Combining the implantation with bone augmentation preserved the alveolar bone and shortened the treatment period.- - - - - - - - - - ranking = 9keywords = extraction (Clic here for more details about this article) |
6/76. Second premolar serial extraction.serial extraction of mandibular second premolars should be considered if they are impacted or in cases with moderate arch length deficiency combined with an absence of dentofacial protrusion. The favorable dental changes associated with this approach greatly minimize future orthodontic treatment complexity and time.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
7/76. Orthodontic, genetic, and periodontal considerations in the treatment of impacted maxillary central incisors: A study of twins.Treatment of twins each with one impacted maxillary central incisor and a mesiodens is described. Treatment included rapid expansion, extraction of the mesiodens, surgical exposure of the impacted central incisor, and its forced eruption. The impacted incisor was brought into functional position in one patient but was lost in the other because of insufficient root length and high mobility. Orthodontic, genetic, and periodontal considerations of these 2 cases are evaluated.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/76. Hemorrhagic diathesis in a carrier of hemophilia b.A carrier of hemophilia b was found to have an unusually low factor ix level of 13 per cent. Her history of previous bleeding and the hospital course following elective dental extractions were consistent with a mild hemorrhagic diathesis. The patient is a member of a rare kindred of hemophiliacs. The mean level of factor ix in 12 carriers in this kindred was 42 per cent, with a range of 13 to 100 per cent. This patient represents the sixth reported case in which a female carrier of factor ix deficiency was symptomatic.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/76. Computed tomography of emphysema following tooth extraction.Subcutaneous and tissue space emphysema following surgical extraction of mandibular third molars is a rare and serious complication of dental surgery. Recognition of mediastinal emphysema following surgical extraction is difficult because there are no absolute clinical symptoms and signs. We present two cases of emphysema following extraction of a lower third molar and discuss the contribution of CT to the early recognition of the presence and spatial migration of air and to clinical management.- - - - - - - - - - ranking = 7keywords = extraction (Clic here for more details about this article) |
10/76. Treatment of a patient with a Class II malocclusion, impacted canine, and severe malalignment.A case report of the orthodontic treatment of a male adolescent with a unilateral dental Class II malocclusion, an impacted canine, severe maxillary malalignment, and a canted maxillary anterior occlusal plane. Treatment consisted of full fixed appliances, extraction of the maxillary right first premolar, and surgical exposure of the impacted canine. Treatment vastly improved the patient's facial and dental esthetics. A Class I skeletal and dental relationship was established, along with a functional anterior guidance. The dental arches were coordinated and the dental midlines coincident with the midsagittal plane. This case report was presented to the American Board of orthodontics in partial fulfillment of the requirements for the certification process conducted by the Board.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
