  • With improvement in technology and research into this field it has vastly changed the way the cases have been treated over years from the days of two dimensional radiogaphy we have reached the era of 3d imaging techiniques …but that does,nt mean we diagnose all cases with the case history ,clinical examinations, BASIC STUDY MODELS ,CEPHALOGRAMS,AND PHOTOGRAPHS IN MAJORITY OF CASES to get close to a comprehensive

  • 10. • However, in the field of orthodontics, at the time of diagnosis, the treatment objectives are set and the diagnosis, as such, is considered only tentative until those treatment objectives are achieved, because the tissue response and the duration, direction and magnitude of growth varies in individual patients. www.indiandentalacademy.com

  • 38. Preventive Orthodontics “Prevention is better than cure” So, “Catch ‘em young” • Preventive orthodontics includes procedures undertaken prior to the onset of a malocclusion in anticipation of a developing malocclusion. www.indiandentalacademy.com
  • 39. • The following are some of the procedures undertaken in preventive orthodontics: 1. 2. 3. 4. 5. Parent education Caries control Supervision of timely tooth shedding Space maintenance Checkup for oral habits and habit breaking appliance if necessary 6. Occlusal equilibration if there are any occlusal prematurities 7. Extraction of supernumerary teeth 8. Management of abnormal frenal attachment www.indiandentalacademy.com
  • 40. Space Maintenance • Premature loss of deciduous teeth can cause drifting of the adjacent teeth into the space. • This can result in abnormal axial inclination of teeth, spacing between teeth and sometimes a shift in the dental midline, i.e. – malocclusion. • Space maintenance is the maintenance of the mesio-distal and vertical width of an arch space created by the loss of deciduous dentition. • The appliances/devices used or intended to be used for this space maintenance are called space maintainers. www.indiandentalacademy.com
  • 41. Removable Partial Denture Crown and loop Lingual Arch Distal Shoe www.indiandentalacademy.com
  • 42. Habits • A habit is ‘an act that has become fixed due to repeated performance.’ • Oral habits in children have a definite bearing on the development of occlusion. • Frequently, children acquire certain habits that may either temporarily or permanently be harmful to dental occlusion and to the supporting structures. www.indiandentalacademy.com
  • 43. • However, when the habit is corrected while the occlusion is still undisturbed and no malocclusion has set in, it is termed as preventive orthodontics. • But, in case the habit has already caused the onset of a malocclusion, the measures applied to correct the habit are termed as ‘interceptive orthodontics’. www.indiandentalacademy.com
  • 44. Interceptive Orthodontics “A stitch in time saves nine” • Interceptive orthodontics includes procedures that are undertaken at an early stage of a malocclusion to eliminate or reduce the severity of the same. www.indiandentalacademy.com
  • 45. • The procedures undertaken interceptive orthodontics include: 1. 2. 3. 4. 5. 6. Serial extraction Correction of developing cross bite Control of abnormal habits Space regaining Muscle exercises Interception of skeletal malrelation www.indiandentalacademy.com in
  • 46. Serial Extraction • The early mixed dentition is easily prone to development of irregularities in the dento-facial complex. • When such potential irregularities are recognized and anticipated, the planned extraction of certain deciduous teeth and later specific permanent teeth in an orderly sequence and pre-determined pattern can help in guiding the erupting permanent teeth into a more favorable position. www.indiandentalacademy.com
  • 47. Correction of developing cross bite Pre treatment Post treatment www.indiandentalacademy.com
  • 48. Interception of Habits • Interception of the habit will cause interception of the developing malocclusion effected by the habit. • Some of the common oral habits: – – – – – – Thumb sucking Tongue thrusting Mouth breathing Bruxism Lip biting Nail biting www.indiandentalacademy.com

  • 165. • The orthodontist uses ‘camouflage’ treatment in cases where the ideal treatment protocol was/is not possible due to some reason or the other, to try and improve the dental occlusion and facial esthetics. • The term ‘camouflage’ is chosen to emphasize that successful treatment must produce “acceptable” facial esthetics as well as “acceptable” dental occlusion. www.indiandentalacademy.com

  • 188. Case 2 Correcting traumatic occlusion www.indiandentalacademy.com
  • 189. Retention “It’s not over till it’s over” “I will give you half my fees if you can retain what I have achieved” • Retention is the phase following active orthodontic treatment aimed at stabilization of achieved orthodontic correction or holding of the teeth in ideal functional esthetic occlusion. www.indiandentalacademy.com
  • 190. Retention is necessary for three reasons:  The gingival and periodontal tissues are affected by orthodontic tooth movements and require time for reorganization, when an active appliance is removed.  After treatment, the teeth are in unstable condition. So the soft tissue pressures constantly produce relapse tendency.  Growth changes can alter orthodontic results. www.indiandentalacademy.com
