Witsenburg B - - 1981
In a retrospective study of 63 patients, an attempt is made to determine in how many cases retained permanent upper incisors erupt after the removal of supernumerary teeth, and what predisposing and etiological factors are of importance. It proved that the eruption of a supernumerary tooth positively contributed to the ...
Duncan W K - - 1981
In this case, a clear pathway for eruption was provided for the mandibular left first permanent molar by reducing the distal surface of the primary molar. The occlusal surface was also surgically uncovered to remove any possibility of a mucosal barrier. It was thought that the loss of arch length ...
Andrews A H - - 1981

A detailed account of 1337 incisors suffering from pure infraction or infraction in conjunction with some form of fracture and/or damage to the supportive tissue as a result of an acute trauma is given. The teeth were examined at ...
Becker A - - 1981
This study reports an exceptionally high incidence of palatal displacement of maxillary cuspids in the presence of anomalous lateral incisors, and explores some of the relationships between these teeth during the critical developmental stages. It is suggested that the possibility of palatal cuspid displacement be evaluated in all cases with ...
Schröder U - - 1981
A new approach to achieve space closure in cases with missing maxillary lateral incisors is presented. The maxillary first primary molar is extracted just before the eruption of the first permanent molar to make mesial drifting into distal occlusion between the permanent molars possible, which is requested to compensate for ...
Cassella E A - - 1981
A case report is presented in which an orthognathically compromised patient presented with a destructive periapical lesion that caused resorption of first and second molar roots and buccal and palatal cortical plates. The initial diagnosis and treatment were influenced by the absence of pre-existing dental records and an unrecountable dental ...
Egyedi P - - 1980
Seven cases of class II skeletal deformities of the face are described in which overcorrection into a class III relationship was performed.
