Patients who lost molars from dental caries or periodontitis have difficulty in maintaining their vertical dimension because their incisors and premolars also show vertical tooth movement. Missing posterior molars leads to occlusal interference and collapse of occlusal plane due to extrusion of opposite teeth and tipping of adjacent teeth. When this condition persists over long time, mandible moves forward, so it causes mobility and labioversion of upper incisors. This progress cannot be stopped spontaneously and the situation gets worse and worse. Therefore, for a patient with pathologic teeth migration caused by chronic periodontitis, interdisciplinary approach which is including periodontal treatment, orthodontic teeth alignment and prosthetic restoration of missing molars is required. This case report shows successful multidisciplinary approach to a patient who lost vertical dimension due to severe dental caries and periodontitis.

Anterior tooth spacing is observed by pathological tooth movement (PTM), which is common in periodontal patients. And various occlusal factors contribute to PTM, especially in the maxillary anterior region, when there is excessive occlusal force, flaring due to position problem easily occurs. Teeth with loss of periodontal support tissue can secure stability when expanding the support area through intentional splinting, and change the occlusion when restored as a fixed prosthesis. After confirming the stable occlusion through the provisional prosthesis, it can be transferred to the final prosthesis through CAD-CAM. In this case, we present a long-term stable case through accurate diagnosis and treatment of the maxillary anterior teeth that have lost interdental contact.

A patient with severe periodontitis has causative factors that cause pathological tooth movement, the occlusion is disintegrated, and the vicious cycle of worsening periodontitis is repeated. In particular, when pathological tooth movement occurs in the maxillary anterior region, the patient has an aesthetic sense of atrophy, and the quality of life was reduced. Therefore, when orthodontic treatment was added to patients with severe periodontitis, it promotes the formation of new bone, reduces periodontal cysts, and obtains clinical attachment, which leads to favorable results in prosthetic restoration, thereby enabling ideal occlusion, function and aesthetics. Periodontal treatment, orthodontic treatment, natural tooth restoration, and implant prosthesis were planned for patients with pathological tooth movement in the anterior region due to loss of occlusal support in the posterior region. As a result, an ideal restoration space was secured, a stable restoration of occlusal contact was formed, and the maxillary anterior teeth were aesthetically improved.

Anticonvulsants, calcium channel blockers and immunosuppressants are representative drugs related with gingival enlargement. Clinical signs and symptoms caused by drug-induced gingival enlargment frequently appear within 1 to 3 months after medication. At initial stage, it is limited to attached gingiva but may extend coronally and interfere with esthetics, mastication and speech. Interproximal spaces are common beginning area and pathologic teeth migration could be occurred by the lesion. Withdrawal or substitution of medication would be the most effective treatment of drug-induced gingival enlargement. However, periodontal treatment and further supportive periodontal therapy should be provided where change in medication is impossible. The present study reports the cases which show the resolution of inflammation with spontaneous teeth migration without change in medication. In all cases discussed in this report could be efficiently managed with proper periodontal treatment and further supportive periodontal therapy.

전치부사이의 비정상적 공간이 생기는 원인은 순측소대, 악궁과 치아의 크기 부조화, 악습관, 과잉치, 치주염으로 인한 병적치아이동 등 다양하다. 이러한 일차적인 원인요소들을 먼저 제거한 후 남게 되는 공간을 해결하기 위해서 교정치료 또는 여러가지 보철수복방법을 고려해 볼 수 있다. 보철적으로 치료할 경우, laminate를 이용하여 심미적인 전치부를 만드는 술식은 보존적인 면에서나 심미적인 면에서 유리한 점이 있어 많이 사용되고 있다. 그러나 인접면사이에 비교적 큰 공간이 존재하며, 감소된 치주조직으로 인하여 치간유두의 소실이 많고 직경이 작은 치경부가 노출되었을 경우에는 laminate를 이용하여 공간을 수복하기가 쉽지 않기 때문에, 교정적으로 치아를 이동시킴으로서 보다 심미적인 결과를 얻을 수 있다. 본 증례는 중등도의 치주질환으로 인하여 치주조직이 감소된 상악중절치에서 정중이개의 양이 비교적 크고 치간유두의 소실 및 직경이 작은 치경부가 노출된 환자에서 laminate를 이용하여 심미적인 공간폐쇄를 도모하였다.

Purpose: Phenylketonuria (PKU) results from a deficiency of phenylalanine hydroxylase (PAH). The mutation of the PAH gene results in decreased phenylalanine hydroxylase enzyme activity in hyperphenylalaninemia (HPA) patients. This study reports ten cases of patients with the benign HPA genotype c.158G>A (p.Arg53His, R53H) variant in the PAH gene and aims to evaluate the clinical significance of the R53H variant. Methods: Ten Korean patients with the HPA genotype the R53H variant were included in this study. A retrospective medical record review was conducted. We characterized the phenotypes of the patients with HPA with the R53H variant using the following system: classic PKU, moderate PKU, mild PKU, Mild HPA, and benign HPA. Results: Five patients had the R53H variant with the "Pathogenic" variants (R413P, R241C, $Y356^*$, c.442-1G>A, $Y325^*$), Two patients had the "Likely pathogenic" variants ($W187^*$, A259T), Two patients had the "Uncertain significance" variants (R53H, G344D), and One patient had the "Not provided" variant (c.1066-14C>G). Nine patients genotyped with the R53H variant were the patient with benign HPA and One patient genotyped with the R53H homozygote was within normal range of plasma phenylalanine. None of the ten patients required dietary restriction of phenylalanine or pharmacotherapy to maintain their plasma phenylalanine levels and showed no clinical symptoms of HPA. Conclusion: Ten patients with HPA genotype the R53H variant were the patient with benign HPA and showed no clinical symptoms of HPA. Thus, the R53H variant, which was previously classified as an "Uncertain significance" mutation in HPA patients, should be re-classified as "Benign."

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.
