Pathologic tooth migration (PTM) caused by periodontal disease is a relatively common disease with a prevalance rate of 30~55%. It is one of the reasons for periodontal treatment of patients. PTM occurs when various factors related to the position of the tooth are altered and clinical features of PTM include facial flaring, diastema, proximal tilting, rotation, and extrusion of teeth. The purpose of this study was to assess the treatment of teeth of hopeless prognosis through the practice of modified intentional replantation on pathologic migrated tooth. This study presents cases using modified intentional replantation for the treatment of pathologic tooth migration caused by severe periodontitis. Modified intentional replantation is a technique that prepares extraction socket by using an implant drill. Based on 3 cases performed with modified intentional replantation, an improvement of clinical periodontal indicators such as probing pocket depth, bleeding on probing, tooth mobility, and pathologic teeth migration was observed after surgery. Also, the patients were satisfied with the functional and esthetic improvement.

Purpose: Pathologic tooth migration (PTM) commonly occurs in the anterior region and is associated with periodontal disease. The treatment of PTM of anterior teeth can be complex and time consuming, and a multidisciplinary approach is often required. Materials and Methods: The patient was a 38-year-old woman with a chief complaint of saving and realigning her elongated maxillary left central incisor. This paper describes the successful combined periodontal regenerative (guided tissue regeneration) and prosthetic treatment and a 2-year follow-up of maxillary central incisor with pathologic tooth migration, deep intrabony defect, and poor prognosis. Results: The right maxillary central incisor was restored by laminate veneer and the left by all-ceramic crown. The patient had no pain and discomfort and was satisfied with the outcomes of her treatment for 2 years. She has maintained her recall program at the Department of Periodontology at 3 months interval. Conclusion: The key step in the successful treatment of PTM in anterior region is to obtain a high level of cooperation from the patient. Maintenance of the treatment result of PTM is dependent on the continuous preservation of periodontal health.

Purpose: Pathologic tooth migration (PTM) is a tooth displacement which is derived from imbalance of tooth retention force and is dominantly found out in maxillary anterior area. PTM in maxillary anterior area was tried to corrected with periodontal treatment and a clear aligner in this study and the result was evaluated clinically and radiographically. Methods: For the treatment of a patient with chronic periodontal disease accompanied by maxillary anterior pathologic tooth migration, clear aligner was applied to move teeth after a series of case-related periodontal therapy. Clinically, probing depth, gingival recession, clinical attachment level and mobility were measured pre- and post-treatment, and radiographic examination was performed as well. Results: Clinically, we found the decrease of the probing depth, gingival recession, clinical attachment level and mobility. And we could also acknowledge the reduction of vertical and horizontal dimension on infrabony defect radiographically. However, it is still controversial if there was an actual bone filling. Conclusions: Clear aligner is an effective appliance to move teeth since it costs little in terms of expense and time. In addition, it wraps whole crowns, providing advantages to deal with crowding, spacing, and size of arch. In short, clear aligner could be a useful treatment option for PTM patient, since it provides decreased probing depth, gingival recession, clinical attachment level, mobility and esthetical restoration.

Generalized aggressive periodontitis cause intrabony pocket, loss of teeth, and severe alveolar bone defect. As a result, pathologic tooth migration occurs and esthetic problem happens according to this, especially on the anterior teeth of maxilla. The purpose of this study was to assess the multidisciplinary treatment including periodontics, orthodontics and prosthetics of a patient caused by generalized aggressive periodontitis. This study presents a case using full mouth periodontal treatment, immediate orthodontic treatment for 5 months, implantation with guided bone regeneration and free gingival graft, and prosthetic treatment. Treatments took totally 14 months. Periodontal indicators such as probing pocket depth, bleeding on probing, tooth mobility improved. Also, the patient was satisfied with the esthetic and functional improvement.

병적 치아 이동된 상악 전치를 가진 중등도 치주염 환자에서는 치태 관리를 통한 치주 염증의 해소뿐만 아니라 치아를 재위치 시키기 위한 교정치료가 함께 필요하다. 이 때의 교정치료는 더 적은 힘의 적용과 치아의 저항중심, 최적의 힘 등을 세심하게 고려해야 하는데, 이동하고자 하는 치아에만 적용되는 분절호선은 이동의 예측성을 높여주고, 힘을 조절할 수 있어 보다 효율적이다. 또한 교정치료 시, 고정원으로 사용되는 치아의 원치 않는 움직임을 차단하여 구치 교합 상태를 유지할 수 있는 장치 설계가 필요하며, 이를 위해 다양한 종류의 골성 고정원이 사용될 수 있다. 본 증례에서는 정출되고 변위된 상악 전치를 가진 환자에서, 철저한 치주 치료와 적절한 힘과 역학이 설계된 교정 장치로, 양호한 치료 결과를 얻을 수 있었으므로, 소개하고자 한다.

치주질환이나 우식으로 인해 구치부 치아가 상실된 환자들은 잔존하고 있는 전치부 및 소구치부 치아로 안정된 교합고경을 유지하기 어렵다. 구치의 상실로 대합치의 정출이나 인접치의 경사가 발생되는 경우 교합평면이 붕괴되거나 부적절한 교합간섭을 야기하게 된다. 만약 치아 상실 상태가 지속된 경우에는 하악의 전방이동으로 인해 상악 전치의 동요와 순측 이개를 초래하게 되며 치주질환이 동반된 경우에는 더욱 심각한 상황으로 변화한다. 이와 같이 치아의 병적 이동이 일어난 환자의 치료는 보존 및 치주치료, 교정 치료를 통한 재배열, 그리고 상실된 치아의 보철수복을 통한 교합 고경의 재설정 및 유지와 같은 다과간 협력 진료가 매우 중요하다.

This case report describes the treatment of an adult female patient with a history of periodontal disease, Class I malocclusion with extrusion, dental spaces, and pathologic tooth migration. The patient was treated with clear aligners, which effectively controlled the strength and direction of orthodontic forces after 3 months of systematic periodontal treatment. The Peer Assessment Rating (PAR) index was calculated from study models before and after treatment. The pretreatment PAR score was 24, and the posttreatment PAR score was 4. The PAR score for this patient changed by 83%. Satisfactory appearance and good function were achieved for this patient.

치아전위는 비교적 드문 발육장애이다. 적절하게 차단치료된다면 예방이 가능할 뿐 아니라 이후의 교정과 수복과정이 보다 용이할 수 있다. 이를 위한 8-9세 경의 조기 임상검사가 이러한 발육장애의 인지를 위해 추천된다. 일단 전위가 일어난 경우에는, 부정교합을 교정하고 최상의 기능적, 심미적 결과를 얻기 위해 주의깊은 교정적 평가가 요구된다. 이상적인 결과를 얻기 위하여 두 치아를 원래의 위치로 환원시키는 치료가 요구되나, 완전전위되어 두 치아가 맹출되었다면 전위된 상태로 치아를 배열하여도 비교적 양호한 결과를 얻을 수 있었다.
