  • Tooth impaction make various problems which are pathologic changes, functional defect and esthetic troubles. Sometimes impacted tooth are extracted. But surgical exposure of impacted tooth and orthodontic forced eruption are usually used a lot to solve these problems. Impacted tooth for orthodontic treatment has two impacted patterns 1) Simple impaction outside alveolar bone covered soft tissue, 2) Fully impaction under alveloar bone. So I introduce way to exposure of impacted tooth for orthodontic treatment with various cases and literatures.

  • Objective: Forced eruption has been proposed for the reconstruction of deficient bone and soft tissue. The aim of this study was to examine the changes in the alveolar ridge width and the vertical levels of the interproximal bone and papilla following forced eruption. Methods: Patients whose hopeless maxillary anterior teeth were expected to undergo severe bone resorption and soft tissue recession upon extraction were recruited. In addition, patients whose maxillary anterior teeth required forced eruption for restoration due to tooth fracture or dental caries were included. Before and after forced eruption, the interproximal bone height was measured by radiographic analysis, and changes in the alveolar ridge width and the interproximal papilla height were measured with an acrylic stent. Results: This prospective study demonstrated that the levels of the interproximal alveolar bone and papilla were significantly increased by 1.36 mm and 1.09 mm, respectively, in the vertical direction. However, the alveolar ridge width was significantly reduced by an average of 0.67 mm in the buccolingual direction. The changes in the level of the interproximal alveolar bone and papilla were positively correlated. Conclusions: Although the levels of the interproximal bone and papilla were significantly increased, the alveolar ridge width was significantly decreased following forced eruption. There was a modest positive and significant correlation between the changes in the height of the interproximal alveolar bone and the papilla. Based on our findings, modification of vertical forced eruption should be considered when augmentation of the alveolar ridge width is required.

  • There have been many treatment methods for traumatic subgingival crown fracture and intrusion without spontaneous eruption. The orthodontic forced eruption generally results in favorable clinical findings than crown lengthening with osteotomy and intentional replantation. In first two cases with subgingival crown fracture due to trauma, authors applied orthodontic forced eruption with axed appliance after root canal therapy and then restored them with composite resin. In another case with traumatic intrusive luxation, we observed spontaneous eruption of the corresponding tooth for about 6 months and then returning it to normal position by forced eruption with removable appliance, but root canal filling was conducted after apexification due to devitalization during forced eruption, and so clinically favorable results were obtained.

  • Forced orthodontic eruption(FOE) is a non-surgical treatment approach that allows augmenting both soft- and hard-tissue profiles of potential implant sites, by forced orthodontic extrusion of "hopeless" teeth and their periodontal apparatus. By stretching the gingival and periodontal ligament fibers during extrusion, tension is imparted to the entire alveolar socket, stimulating osseous apposition at the alveolar crest. FOE increases the width of the attached gingiva, and the mucogingival junction remains stable when the gingival margin migrates coronally. Based on these effects, FOE of non-restorable teeth prior to implant placement is a viable alternative to conventional surgical augmentative procedures in implant site development. The aim of this case report is to describes coronal soft-tissue augmentation around fractured teeth, which was achieved by FOE before implant placement.

  • This case report presents two maxillary anterior cases for clinical crown lengthening by forced eruption. In the first case, clinical crown of maxillary right lateral incisor was almost lost by fracture. Forced eruption using intracoronal splint and elastic thread accomplished vertical root movement successfully. Then, post & core was inserted and final restoration was harmonious with adjacent teeth. In the second case, the crown portion of maxillary right central incisor was almost mutilated by secondary caries. Forced eruption using removable Hawley appliance and elastic accomplished vertical root movement successfully. Then, post & core was inserted and final restoration was placed. In conclusion, clinical crown lengthening by vertical root movement can be accomplished by a simple appliance without any sacrifice of periodontal support in selected patients. A clinical crown so created can be restored to adequate function and arch integrity without compromising adjacent teeth. Therefore, forced eruption is preferred in the anterior region of the dentition where esthetics is of major concern.

  • Impaction of permanent incisor occurs rare than the canine & third molar. But it's often observed in school age child. The causes of impaction are trauma, space deficiency, mesiodens, infections of root apex, etc. In spite of elimination of cause, normal eruption of impacted tooth is rare. Though eruption is normal, the position of tooth will be incorrect. Because the impacted tooth results in malocclusion, root resorption of adjacent tooth, pathologic cystic change, it should be confirmed the precise position by clinical and radiographic exam and found the correct location by appropriate treatment plan. In case of pathologic change of impacted tooth and injury to adjacent tooth, it will be extracted. But through orthodontic retraction, the function and esthetics of tooth can be restored. It is important that impacted tooth should be detected early and diagnosed correctly, and appropriate treatment plan should be made. Before impacted tooth is retracted, the considerations of space for alignment and anchorage should be preceded and through appropriate force and mechanics, the side effects, for example, a root resorption should be minimized. In this study, we guided impacted tooth to normal position by using a forced eruption.

  • A subgingival crown-root fracture presents a restorative problem to the clinician because restoration is complicated by the need to maintain the sound tooth structures. Forced eruption offers a method of treatment of teeth fractured close to the alveolar crest. Extrusion of such teeth allows elevating the fracture line above the epitherial attachment and so the proper finishing margins can be prepared. The purpose of this case is to report successful tooth restoration using forced eruption in case of crown-root fractures.

  • In the case of crown-root fracture due to traumatic injury in anterior tooth and the fracture margin is located subgingivally, forced eruption has been proposed for the reconstruction of deficient bone and soft tissue. Forced eruption is one of the easiest orthodontic approaches that can have an acceptable outcome and prognosis, and has a low incidence of relapse. However, using heavy forces or very fast movements can also cause tissue damage or ankylosis. The following case reports present forced eruption as treatment option of crown fracture in maxillary anterior teeth.

  • Tooth impaction represents the stop of eruption by clinical and radiographical disturbance in eruption path or the dislocation of tooth germ. The most common factor in tooth eruption disorders are spacial deficiency with other causes reported to be odontogenic tumors, periodontal ligament injury, etc. Impaction of the mandibular second molar is relatively rare and reported in about 3 out of 1,000 people. Because the second molars tend to erupt in a mesial direction, this situation can lead to serious problems if untreated, including dental caries, periodontal disease and root resorption of the first molar. Treatment of this problem includes, surgical repositioning and orthodontic forced eruption. Because each procedure have the definite advantages and disadvantages, and influenced by circumferential environment, these have limits for successfu1 recovery as independent treatment. In a case at St. Mary's Hospital, we performed successful correction of a horizontal impacted mandibular second molar using a miniplate skeletal anchorage system. We introduce this treatment as a valid method for an impacted second molar and consider a oromaxillofacial surgeon's role in tooth movement treatment.
