  • 1- Describe the canine relationship (dent463_final200620073_fig01)The canine relationship is: Class I Half unite Class II Full unite class II Half unite Class III Full unite class III

  • 2-Identify the problem in the upper arch.3- What is the treatment? (dent463_final200620073_fig02)The Problem in the upper arch is: Impaction Delayed eruption Infraocclusion traumatic intrusion(dent463_final200620073_fig02)The treatment for the problem in the upper arch is: Nothing Observation Extraction Extrusion

  • 4- what is this functional appliance?5-what is it used for?(dent463_final200620073_fig03)The appliance shown in the picture is Twin block Andersen Bionater Franckle II (dent463_final200620073_fig03)The main effect for the appliance shown in the picture is restrict maxillary growth enhance mandibular growth procline lower incisors retrocline upper incisors

  • 6+7 List 2 occlusal features you are likely to find in this patient(dent463_final200620073_fig04) The malocclusion most likely to be seen in this patient is open bite anterior cross bite posterior cross bite increased over jet (dent463_final200620073_fig04) The best time for treating this habit is: 3 years 5 years 7 years 9 years

  • 8- Beside esthetics give another reason to treat this malocclusion2-Infraocclusion3- Observation

  • 9-what is the anomaly in the lateral incisor?

  • 10+11 give 2 types of active components in this removable appliance(dent463_final200620073_fig05) how many types of active components could be seen in this removable appliance: 1 2 3 4 (dent463_final200620073_fig05) The type of anchorage that could be seen in this removable appliance is: reciprocal stationary extra-oral Two answers are correct(dent463_final200620073_fig05) anchorage loss during the use of this removable appliance is manifested as: increase in the overjet change in the molar relationship change in the canine relationship Two answers are correct all the above

  • 12 Describe (orthodontically) the lips of this patient(dent463_final200620073_fig06) The lips of this patient is: competent potentially competent incompetent potentially incompetent

  • 13- What is the incisor relationship(dent463_final200620073_fig07) The incisor relationship is: Class I Class II division 1 Class II division 2 Class III

  • 14- Describe the profile of this patient15- what is the anteroposterior skeletal relationship

  • 16 what is the active component in this removable appliance?17 how it is activated?

    (dent463_final200620073_fig08) this is: rapid expansion screw hyrax screw upper part of twin block mid-palatal expansion screw(dent463_final200620073_fig08) one opening of this screw will give an expansion of: 0.25 mm 0.5 mm 1 mm 2 mm

  • 18 what is this?19 give one indication for its use20 give one disadvantage(dent463_final200620073_fig09) this is: first generation permanent retainer second generation permanent retainer third generation permanent retainer fourth generation permanent retainer(dent463_final200620073_fig09) this is indicated in cases of: rotated lower incisors spaced lower incisors where lower incisors were orthodontically proclined two answers are correct all the above

  • 21 what is the incisor relationship

  • 22+23 list 2 orthodontic problems in the upper arch

  • 24 what is the name of this appliance?25 what does it used for?

  • 26 what is the most likely cause for delayed eruption of the upper central incisor?

  • 27 what is indicated by the arrow?(dent463_final200620073_fig10) the line indicated by the arrow is: mandibular plane maxillary plane Frankfort plane S-N line

  • 28 what facial deformity could be seen in these radiographs

  • 29- what is the position of the impacted canine relative to the line of the arch?30- what is the name of this radiographic localization technique?31- give one possible etiological factor for this impaction(dent463_final200620073_fig11) the position of this imacted canine is: buccal palatal in line of the arch

  • 32 what is this appliance?33 what does it used for?(dent463_final200620073_fig12) this is: bonded rapid expansion screw banded rapid expansion screw mid-palatal expansion screw(dent463_final200620073_fig12) the expansion resulted from this appliance is: dental skeletal(dent463_final200620073_fig12) This appliance is opened: once a week twice a week once a day twice a day

  • 34 what is the dental anomaly?35 what is the name of the surgical exposure technique36 give on advantage of this technique37 give one disadvantage

    (dent463_final200620073_fig13) this exposure method is: open exposure closed exposure

  • 38 can we retract this canine with removable appliance39 why?40 what active component would you use if you can?

  • 41+42 what are the treatment options for missing lower second premolar?(dent463_final200620073_fig14) the incisor relationship is: Class I Class II division 1 Class II division 2 Class III(dent463_final200620073_fig14) the best treatment for the missing lower second premolars in this case is to: close the space open the space

  • 43 what do we call the condition affected the upper left central incisor?

  • 44-What is the treatment option for these missing lower incisors ( open or close space)?(dent463_final200620073_fig15) the best treatment for the missing lower incisors in this case is to: close the space open the space
