Evaluation of total reaction forces showed that with lowering the simulated occlusal interference total reaction forces of maxillary dental arch
gradually decreased in axis X and increased in axis Y, while their effects in axis Z changed unevenly; this was caused by significant change of magnitude and direction of lateral force arisen in teeth 13 when simulated occlusal interference was of height 0.
Formation of the geometrical model of the gypsum model of the whole dental arch
All dental arch
measurement were made directly from the dental cast manually using a digital sliding caliper (Chenqdu tenggiang industry co.
Another problem that may arise in connection with the eruption of the permanent teeth is ectopic eruption, which might result in a deviation of the tooth in the dental arch
and difficulty in function of the teeth.

Loss of dental arch
circumference due to premature loss of primary molars is a common presentation in the primary and mixed dentitions.
An alginate impression is taken of the patient's affected dental arch
, either during the extraction visit or at a later appointment after healing has occurred; a working model is produced.
