The anterior maxillary incisor is the most traumatized region in the mouth and trauma is frequent between the ages of 8-10. Traumatic loss of teeth, can lead to many complications in children. Thus, as possible to keep traumatic teeth, but if you need extractions There may be. Complications occur and early tooth loss is frequent. Complications of early loss of central incisors are esthetic compromise, loss of vertical and horizontal width, height, contour of alveolar bone, tilting of adjacent teeth, arch length loss. Alveolar bone loss may affect normal function and stability, and results in esthetic problem for future prosthesis restoration. The 9-year-old girl and 6-year-old boy got early loss of upper central incisor. The amount of alveolar bone resorption was measured using cone beam computed tomograph and cast analysis.

The primary cause of missing teeth vary depending on the region. The loss of posterior teeth is mainly due to dental caries, whereas that of the anterior teeth occur primarily due to trauma at the age of standing and walking and secondarily from the rampant dental caries. Particularly, reduction of the arch length in the cases of premature loss of primary teeth may compromise the eruption of succedaneous permanent teeth. This may result in crowding and impaction of the permanent teeth, and asymmetry of arch, thus a careful consideration for space maintenance should be made in such cases. Space maintainer is required in the case of premature loss of primary posterior teeth, because space loss result from the approximate and centrifugal movement of the neighboring teeth. Generally, in the case of primary incisor, space loss occurs when 1) tooth contact is relevant, 2) crowding in primary dentition is present, and 3) a primary incisor is lost before the eruption of primary canine. Contrarily, in the case of primary dentition with interdental space, space loss will not be observed, mostly when a primary incisor is lost after the eruption of primary canine. Thus, using a space maintainer in cases of premature loss of primary incisor has been introduced primarily not for the purpose of space maintaining but for an aesthetic purpose, prevention of parafunctional oral habits such as tongue thrust, and of pronunciation. Additionally, few case studies have been reported of space loss in cases of premature loss of primary incisor. This study is to report cases of the space loss following the premature loss of primary incisors observed in children.

Premature loss of maxillary primary incisors often results from early childhood caries (ECC), trauma. While space maintenance in the posterior region is an important consideration when there is early loss of primary molars, the anterior segment appears to be stable, even with the early loss of several incisors, once the primary canines erupt. However, collapse of anterior arch integrity is evident in cases where incisor teeth are in a crowded dentition prior to extraction or lost before the eruption of the primary canines. So, when early loss of maxillary primary incisors, the aim of restoration is esthetics, speech problem, oral habit such as tongue thrusting than space maintenance. This paper reports that the esthetic problem due to premature loss of maxillary incisors can be successfully resolved by soldered open-faced stainless steel crown.

In the case of single tooth replacement, a fixed prosthesis or a dental implant is the treatment option commonly selected as first choice. However, any amount of sound tooth structure should be removed to prepare the abutment teeth for full coverage retainer. The adjacent tooth damage can be avoided placing a dental implant. However, depending on the patient's oral condition and any other circumstances, it may be impossible or delayed. In this case resin bonded fixed partial denture was selected as an alternative that can restore single tooth loss without much tooth structure removal to the young patients and the patients with gingival recession. We report these patients were satisfied with esthetic and function.

오늘날 단일치 임플란트의 식립은 현재 시행되고 있는 가장 일반적인 임플란트 술식 중 하나이며, 상악 전치부는 이중 가장 흔하게 시행되는 식립 부위 중하나이다. 그럼에도 불구하고 상악 전치부 단일 상실치에 대한 치료 계획은 구강 내 다른 어떤 부위보다 복잡하며 고도로 심미성을 요구하는 부위로서 아무리 경험이 많고 기술이 뛰어난 치과의사라 할지라도 시술할 때마다 큰 도전으로 여겨지는 경우가 대부분일 것이다. 상악 전치부에서 임플란트 보철의 심미적 성공을 이루기 위해서는 모든 구성 요소 하나하나에서 심미적 결과를 이룩하여야 하고 이 결과들이 완벽하게 조화를 이루게 하여야 하며 이는 결코 쉬운 일이 아닐 것이다. 시술 시 교과서의 그림처럼, 모형에 식립해 본 것처럼 쉽게 되지 않는 것은 물론 구강 내 환경이 모형과 다를 리 만무한 것이 당연한 첫 번째 이유이며 뿐만 아니라 환자 대부분의 경우 모형처럼 완벽한 경 연조직이 갖추어진 상태에서 치아만 상실된 경우는 거의 찾아볼 수 없기 때문인 이유도 크다. 즉, 원하는 위치에 식립을 하고 장기간의 심미적 유지를 위해서는 경 연조직에 대한 처치가 필수적인 경우가 대부분이라는 이야기이다. 이를 간과하고 식립한 경우 추후 심각한 bone의 resorption, 그에 따르는 gingiva의 끔찍한 recession, 용납할 수 없는 비심미적 보철물의 제작은 불을 보듯 뻔한 결과가 될 것이다. 따라서 상악 전치부 식립 치료계획 시 치과의사는 성공적 결과에 영향을 미칠 수 있는 모든 요소에 촉각을 곤두세우고 이들의 완벽한 처치에 최선을 다 해야할 것이다.
