Class II correction in patients treated with

Class II elastics and with fixed functional

appliances A comparative study

In the Begg group the maxilla moved forward 1 mm more than in the Herbst group and the mandible moved 1 mm more in the Herbst group than in the Begg group The skeletal improvement in the Herbst group exceeded the changes in the Begg group by on average 20 mm (P lt 01) The overjet reduction in the Begg group was larger (21 mm P lt 01) than in the Herbst group mostly because of dental movements The skeletal part of the overjet reduction was 4 in the Begg group compared with 51 in the Herbst group The molar correction was similar in both groups but in the Begg group the skeletal improvement was 10 compared with 66 in the Herbst group The overbite correction and the increase in the anterior lower facial height and in the NSLML angle were larger in the Begg group (P lt 05) The conclusions of this study were that the changes contributing to the Class II corrections in Begg and Herbst therapy were skeletal and dental The skeletal changes were however larger in the Herbsttreated group On the other hand favorable and unfavorable vertical changes were more pronounced in the group treated with Class II elastics

bull Although Class II elastics have been widely used in the correction of Class II malocclusions there is still a belief that their side effects override the intended objectives The aim of this systematic review was to evaluate the true effects of Class II elastics in Class II malocclusion treatment

Based on the current literature we can state that Class II elastics are effective in correcting Class II malocclusions and their effects are primarily dentoalveolar Therefore they are similar to the effects of fixed functional appliances in the long term placing these 2 methods close to each other when evaluating treatment effectiveness Little attention has been given to the effects of Class II elastics on the soft tissues in Class II malocclusion treatment

Correction of Class II malocclusion with

Class II elastics a systematic review

bull Although Class II elastics have been widely used in the correction of Class II malocclusions there is still a belief that their side effects override the intended objectives The aim of this systematic review was to evaluate the true effects of Class II elastics in Class II malocclusion treatment

Based on the current literature we can state that Class II elastics are effective in correcting Class II malocclusions and their effects are primarily dentoalveolar Therefore they are similar to the effects of fixed functional appliances in the long term placing these 2 methods close to each other when evaluating treatment effectiveness Little attention has been given to the effects of Class II elastics on the soft tissues in Class II malocclusion treatment

In the Begg group the maxilla moved forward 1 mm more than in the Herbst group and the mandible moved 1 mm more in the Herbst group than in the Begg group The skeletal improvement in the Herbst group exceeded the changes in the Begg group by on average 20 mm (P lt 01) The overjet reduction in the Begg group was larger (21 mm P lt 01) than in the Herbst group mostly because of dental movements The skeletal part of the overjet reduction was 4 in the Begg group compared with 51 in the Herbst group The molar correction was similar in both groups but in the Begg group the skeletal improvement was 10 compared with 66 in the Herbst group The overbite correction and the increase in the anterior lower facial height and in the NSLML angle were larger in the Begg group (P lt 05) The conclusions of this study were that the changes contributing to the Class II corrections in Begg and Herbst therapy were skeletal and dental The skeletal changes were however larger in the Herbsttreated group On the other hand favorable and unfavorable vertical changes were more pronounced in the group treated with Class II elastics

There were significant increases in facial and maxillary widths for the BBME

bone expansion at the level of the hard palate The TBMEs produced more

dental expansion buccal rolling and a greater increase in nasal width than did

the BBMEs

Hyrax vs Hybrid hyrax

20 growing girls (ages 12 6 06 years)

There were significant increases in facial and maxillary widths for the BBME

group and in nasal width for the TBME group Both expanders produced basal

bone expansion at the level of the hard palate The TBMEs produced more

dental expansion buccal rolling and a greater increase in nasal width than did

the BBMEs

1 Both tooth-borne and tooth-bone-borne RME are effective methods for the treatment of maxillary constriction

2 The hyrax and the hybrid hyrax expanders resulted in similar skeletal effects

3 The hyrax appliance resulted in greater expansion in the premolar region than did the hybrid hyrax

4 Both appliances reduced the buccal bone thickness and increased the palatal bone thickness in the molar area

5 Buccal bone thickness decreased in the premolar area in the purely tooth-borne group whereas the buccal bone

thickness in the hybrid hyrax group was maintained

Edgewise vs Molar intrusion

From the cephalometric values in the non-

IA group open-bite patients were generally

treated by extrusion of the maxillary and

mandibular incisors that resulted in

clockwise rotation of the mandibular plane

angle In the IA group intrusion of the

maxillary and mandibular molars that

resulted in counterclockwise rotation was

noted (n=30 with 2 years followup) Deguchi et al 2011 AJODO

Intrusion of the maxillary posterior teeth can give satisfactory correction of moderately severe anterior

open bites but 05 to 15 mm of reeruption of these teeth is likely to occur Controlling the vertical

position of the mandibular molars so that they do not erupt as the maxillary teeth are intruded is important in

obtaining a decrease in face height Scheffler et al 2014 AJODO

bone expansion at the level of the hard palate The TBMEs produced more
