[Factors impeding obstructed teeth in their eruption. Case report].

With preparation of six study cases the objective of the authors was to abrow colleagues' attention to the fact that teeth remained in impactio and retention might cause complaints not only due to normal anatomical reasons but some complications might occur resulting from anomaly of development. The authors consider the topic extremely important by reason of the case's varieties and the clinical observations made recently and frequently. An increased attention to this case is reasonable since eruption of teeth might happen in case of removal of obstructic fact in time, permanent row of teeth returns to normal, and adequate dental arch might develop. It is also obvious that medical treatment of impact abnormalities derived from anomaly has lack of exact therapy theories, only general protocol can be provided.
