Subtraction method for severe dental crowding He incisor bite of induction

j canine pan outside the press without clearance, and 4 l ~ 1.5ram between the two is about to ask Velvet c, 1 down two of the question, asked about the existence 2ram dry, treatment should be subject to the rule permanent. 2 dental treatment through general rule of dentition analysis, forecasting and development of permanent teeth after I Sit there is still heavy congestion, to decide whether to take measures for dental treatment incisor crowding. Overall analysis of dentition dentition stage twenty minutes, one side turned the eruption of permanent teeth is not projected group (canine, first and second premolar) in width. 0110 Main application regression equation, Moyers, West China Medical projection table and a large table Ono equation is estimated over 4 capsule mandibular incisor to the upper and lower projections Oh f Jie Fang eruption of permanent teeth is not the width of the total group, the men and women are different. Moyers and graduated with a projection table table West Medical projections, we whichever is the probability value of 75 as a reference value. Second, analysis of the dentition dentition jade. When the neck arch length available arch length less than the projected 8ram above mandibular arch length available arch length than the Ke less 5ram measured above belong to the treatment of indications. According to the method of selecting fell ill, the development of careful treatment planning, regular feeding concept of pain in patients with typical Village 3 male, 9 years old, on the incisors I. Crowded, and nearly the reverse,[link widoczny dla zalogowanych], the gap of about 3ram, palatal eruption l leek turn overlap the lower incisors crowding TT I lost earlier. 2ram between the dry smell the rain, the upper and lower first molar is neutral fine relationship. Treatment steps are as follows: (1) Overall dentition to mixed dentition analysis. The sum of the width of upper incisors 36ram, the degree actually the sum of the lower incisors 26ram. Near the top right of the first permanent tooth surface close to the left of the first unit, 210008 Nanjing Stomatological Hospital Children's teeth, 273J molar mesial surface distance 75m ~ 'l, lower right first molar to the left near the surface of the first near the surface of a molar distance of 68n ~ 'n projections permanent base on the width of the side Jie Total: ① Ono regression equation: extrapolated with the four upper incisors permanent base on the leading side of the width of 24.796mm. ② Moyers projection side of the table come awarded permanent base on the width of 24.2ram. @ West China University of Dayton on the projection side of the table obtained permanent base width 24.4ram. Projections under the collar side of the base width and the sum of the permanent teeth: ① Ono regression equation: The lower incisors extrapolated under Jie Jie side of the permanent teeth under the group width 23.328mm. @ Moyers projections table group obtained permanent mandibular lateral width Z4.00r ~ m. ③ Huaxi Medical University awarded under the projection side of the table come to a width of permanent group 23.6ram. Obtained by the analysis: the maximum length of less than maxillary arch 10.592mm, the smallest less than 9.4ram. Mandibular arch length is less than the maximum 6ram, the smallest less than 4.856mm. (2) removal of Double Oh f Rujian maxillary teeth aligned upper and lower incisors. Rujian tooth extraction, the upper and lower first molar adhesive band, and I teeth were stuck with double brackets, 0.014 inch nickel titanium wire ligation the upper and lower teeth aligned, and then remove fixed appliances, with a retainer, treatment regimen for 8 weeks. (3) first premolar extraction. This patient is the first maxillary first premolar eruption in the last Jie Heng canine, and lower left canine collar first premolar erupted before. Therefore, when the eruption of permanent canine, the dentition do a political analysis, concluded that no significant difference with the previous,[link widoczny dla zalogowanych], so were the first pair of missing teeth on the Jie,[link widoczny dla zalogowanych], left lower first deciduous molar, first premolar extraction, constant tip smooth tooth eruption in place. (4) to bite the end of induction therapy units, the measured upper right second premolar tooth loss of smell and some 1.5ram gap. Distal axial tilt canine teeth, the lower left second premolar and the canine between between 1ram. Constant need of orthodontic tooth. 4 Overall serious discussion incisor dentition crowding is due to lack of arch length can not accommodate the number of teeth caused. Some scholars have pointed out. When a child is 6 years after the first permanent molar eruption, is no longer Jie basic bone growth front. From the side of the first permanent molar in the face to the other side along the arch near the surface of the first permanent molars usually will not increase the distance between. Replace the side arm to do the replacement when the smell produced Velvet Underground Solution c incisor crowding can be partly due to the first molar is the rear boundaries of regret, its understanding of the extent of the drum is limited. If the method used to expand the dental arch is generally believed that the increase in arch length will not exceed 3ram, it is a serious lack of arch length method must be used to solve subtraction. Therefore,[link widoczny dla zalogowanych], accurate diagnosis,[link widoczny dla zalogowanych], indications, and careful planning strictly under the decreases in tooth extraction and tooth bite sets of induction therapy for severe cut Kui is a viable means crowded, you can lift the crowd early and shorten the course of permanent teeth treatment. Saves time for patients and financial resources. (Received r1998 One O 'One 13, 1998 a tragic return to l0-16) (this editor: Song Zhaosou)
