Ankylosis is defined as a fusion of alveolar bone with dentin and/or cementum and
may occur at any time during or following active eruption. Ankylosed teeth maintain
existing occlusal levels while adjacent teeth continue to erupt via deposition of alveolar
bone. This may result in the clinical appearance of depression or submergence of
ankylosed teeth below the occlusal plane. It is more frequently in children of late mixed
dentition and in mandibular primary molars. The problems arising from ankylosed teeth,
due to their submerged positions, are elongation of the antagonist, tipping of the
adjacent teeth, loss of arch length, food impaction and subsequent destruction of
periodontal tissue, disturbance of succedaneous tooth eruption. The author observed
several cases of ankylosed primary molars and properly managed. Following results
were obtained.
1. Severe infraoccluded ankylosis results in loss of arch length and undesirable effect in
eruption path of succedaneous tooth, therefore early diagnosis and management are
important.
2. The teeth without problems may be examined periodically and restored in order to
maintain the normal occlusal function.
