Abstract
This paper is a description of the growth and development of the alveolar ridge after extraction of deciduous teeth for the purpose of handling the appliance for denture guidance and its clinical application.
The regions observed were regions of the maxillary and mandibular deciduous molars and maxillary deciduous incisors, frequently causing premature loss of deciduous teeth.
Changes of the alveolar ridge width after extraction in all regions can be divided into the following three phases; decreasing, stable, increasing. The decreasing phase finished about four months after the extraction. The increasing phase began from about eight months prior to the emergence of the succedaneous teeth.
