The eruption times of permanent teeth in children after the early extraction of primary maxillary incisors
The determination of the permanent teeth eruption times in the early mixed dentition in children after the early loss of primary maxillary incisors was hold. The children of the primary school age from 7 to 8 years old were investigated, 3 grades of teeth eruption were determined. The eruption times of first molars in the control group and in the group with the preventive prosthetics matched the standard eruption times, the eruption times in the group without the preventive prosthetics were later. Children without the preventive prosthetics had the delayed eruption of central and lateral incisors. Lateral mandibular incisors in children after the early maxillary incisor extraction erupted earlier, than in physiological teeth change.
