| Adult patients with osseous class ? for significant surface type,because of its beauty and to go to a doctor,adults because of missing the opportunity of adolescent function correction,can only through the cover of orthodontic treatment or orthodontic is jaw joint to improve.But many such patients and clinical risk is due to the jaw surgery tend to conceal sexual orthodontic treatment,conceal sexual orthodontic treatment requires the right to use all kinds of orthodontic palatal tools through vicarious orthodontic treatment mask patients face type.In recent years,micro planting nail the palatal in orthodontic using the dominant position,clinical routine planting nail was implanted in the buccal side,but in the position to grasp the improper implant process easily,cause periodontal ligament damage root perforation caused or covered by buccal mucosa after implantation planting nail implant failure,and jaws because its have enough bone thickness,anatomical structure is relatively simple,does not encroach on the tooth clearance,patients feel comfortable,and clear view of more and more widely used in orthodontic clinic.In recent years,the palate micro-implant anchorage molars begin to push away widely used in[1],down teeth[2],rapid palatal expansion[3]and lingual orthodontics and other orthodontic treatment.This experiment mainly divided into two parts in adult patients with osseous class ? jaws bone thickness were studied:Experiment One:adult skeletal class ? Luzhou,Sichuan region of sagittal and vertical composition analysisbjective:To understand the adult skeletal class ? region of Sichuan Luzhou sagittal and vertical composition analysis.Methods:2013 to 2014 in our hospital 131 cases of adult skeletal Class ? patients aged 18 to 35 years old.Respectively sagittal and vertical parting study,only divided by sagittal:S1 maxillary mandibular overgrown but is normal;S2 overgrown maxillary and mandibular hypoplasia accompanied;S3 developed normally but maxillary jaw but there is lack of development;S4 on the lower jaw were developing normally;S5 are present on the mandibular overgrowth;S6 are present on the mandibular hypoplasia.Vertically divided:G1 high angle;G2 are angle;G3 low angle.Results:The sagittal type to S3 where the largest proportion of about 49.3%(51.7%for males and 47.8%females),followed by S4 approximately 27.2%(21.7%for males and 31.1%for women),the smallest S2 model is about 1.3%(1.6%for males and 1.1%females).Vertical typing angle to G2 are mostly composed ratio of about 50.1%,G1 high angle 28.6%,G3 low angle of 21.3%.In the sagittal direction perpendicular to the packet with the largest proportion in G2S3.Conclusion:1.Sichuan Luzhou regional adult patients with skeletal Class ? sagittal type,mainly in the development of normal maxillary hypoplasia with mandibular based.2.Sichuan Luzhou regional adult patients with skeletal Class ? type vertical angle to both the main.3.Sichuan Luzhou regional adult patients with skeletal Class ? high-angle,both angle and low angle are being developed with the mandibular maxillary and mandibular hypoplasia were developmentally normal two main type.4.In the sagittal and vertical Malocclusion with typing angle are the main types are associated with the development of normal maxillary mandibular hypoplasia.Experiment Two:adult skeletal class ? CBCT form different vertical facial types palatal bone thickness analysisObjective:In this study,bone type ? class adult palate bone thickness in different regions with different vertical facial type of conduct CBCT measurements,respectively,bone type ? class high-angle,both angles palate bone thickness of the low angle of adult patients measurement and analysis and pairwise comparisons between bone type ? class explore different vertical facial type in adult patients palatal bone thickness is different,providing palatal implant for bone type ? class adult patients in clinical reference.Methods:Hospital in 2013 to 2014 in our hospital 98 cases of bone type ? class adult patients aged 18 to 35 years,according to the vertical facial types are divided into high-angle,both angles,low-angle groups of men and women a ratio 1.select the patient's CBCT imaging data,import CS 3D Imagine software reconstruction,measuring the thickness of the palate bone 36 points,36 points will be divided into four transverse,longitudinal three total 12 zones.Use SPSS 17.0 software for statistical analysis of the measurement values.Results:1 Portrait 4 groups packet,high-angle,both angles,low-angle three groups are in addition to the palatal raphe area from front to back bone thickness increases beyond(P<0.05),the remaining palate raphe next area,palatal area,palate front to back off area decreased(P<0.01);2.transverse three packets,high-angle,both angles,low-angle three former district palatal bone thickness parts are from the middle to the sides gradually increased(P<0.01);in addition to the low angle of the jaw after copies zone,high-angle,both angle and low angle of the palate in parts of area,after the palate from the middle to the sides of copies zone are from large to small and then larger(P<0.01);3.12 area measurements in palatal seam parts area,after palatal seam zone,the former parts area palate side seam,palatal before copies District 4 area high-angle group palatal bone thickness greater than average angle and low-angle group(P<0.05);the former parts of the low-angle region next to the palate only group less than high-angle group(P<0.05);palatal lateral parts of area high angle and both groups were lower than the low-angle corner group palatal bone thickness(P<0.05);4.palatal raphe area,next to the palatal raphe area,palatal area,parts of the palate before the next area is a security zone of palatal implant micro.Conclusion:1.Higher,lower,the three groups of patients with type ? adult bone in front of the whole palatal raphe area,and the district of a bone are thicker,palate is planting nail implanted safety area.2.2.High Angle type ? class palatine bone after raphe and palatal raphe area,palatal side area,palatal side area before the three parts of the copy of the area more thicker than the rest of the two groups of bone thickness can meet relatively longer micro planting nail implanted.3 is high,the lower,the three groups of patients with type ? adult bone near the palatal raphe during and after;Palatal side during and after;Palatal side during and after,thin bone thickness can not meet the minimum 4 mm micro planting nail implanted there are risks through the nasal floor,should be noticed clinically. |
