    • Introduction: Prevention is not only better than cure but more stable and cheaper as well. Preventive orthodontics is that part of orthodontics which is concerned with 1.Patients & parents education. 2.Supervision of the growth & development of the dentition & the craniofacial structures. 3.The diagnosis procedures undertaken to predict the appearance of malocclusion. 4.The treatment procedures instituted to prevent the onset of malocclusion.  www.indiandentalacademy.com
    •  Preventive measures undertaken: Parent counselling. Caries control. Exfoliation of deciduous teeth. Abnormal frenal attachment. Treatment of locked permanent first molars. Abnormal oral musculature & related habits. Space maintenance. www.indiandentalacademy.com
    •  Parent counselling -prenatal counselling -postnatal counselling Caries controlEspecially proximal caries detection. can be prevented by diet counselling, topical fluoride application, pit & fissure sealants, educating the parents about caries detection. www.indiandentalacademy.com
    • Exfoliation of deciduous teeth includes Extraction of over-retained deciduous/root stumps. Extraction of supernumerary teeth.   Abnormal frenal attachment may cause the development of diastemas/spacing between the teeth,which in turn may not allow the eruption of succedaneous teeth. This should be surgically corrected. www.indiandentalacademy.com
    • Treatment of locked permanent first molars. Slight distal stripping of deciduous second molars allows the permanent first molar to erupt in their right place. Abnormal oral musculature & habits. -tongue thrusting. -thumb/digit/lip sucking. -mouth breathing. -hypermentalis action. www.indiandentalacademy.com
    •  Space Maintainers:-  Definition :- Space maintainers are defined as the appliances that prevent loss of arch length and which in turn guide the permanent tooth into a correct position, in the dental arch.  Factors to be considered for space maintainance:1.Time elapsed since loss of tooth:-within 2weeks to of extraction. 2.Dental age of the patient 3.Amount of bone covering the developing permanent teeth www.indiandentalacademy.com
    • 4.Stage of root formation 5.Sequence of teeth eruption 6.Congenital missing teeth 7.Eruption of permanent teeth in opposite arch Classification of space maintainers:According to Hitchcock:1.Removable or fixed or semifixed. 2.With bands or without bands. 3.Functional or Nonfunctional. 4.Active or Passive. 5.Certain combinations of the above. www.indiandentalacademy.com
    • According to Raymond C.Thurow:1.Removable 2.Complete arch Lingual arch Extra-oral anchorage 3.Individual tooth According to Hinrichsen:1.Fixed space maintainers class I a} Non functional types- Bar type -Loop type b} Functional types- Pontic type - Lingual arch type class II cantilever type (distal shoe, band and loop) 2.Removable space maintainer:- Acrylic partial denture  www.indiandentalacademy.com
    •  Requirements of space maintainers:- -Maintain mesio-distal width. -Must restore the Function. -Simple in construction. -Strong enough to withstand functional forces. -Should not exert excessive stress on adjoining teeth. -Must permit maintenance of oral hygiene. -Must not restrict normal growth & development. -Should not come in way of other functions. www.indiandentalacademy.com
    •  Advantages of Removable space maintainers:-easy to clean. -serve important function like mastication, esthetics & phonetics -can be worn part time allowing circulation to soft tissues. -maintain or restore vertical dimension. -dental check up can be done for caries detection. -stimulate eruption of teeth. -help in preventing development of tongue thrust in extraction space. www.indiandentalacademy.com
    •  Disadvantages - - - of removable space maintainer May be lost or broken by the patient. Uncooperative patient may not wear the appliance. Lateral jaw growth may be restricted, if clasps are incorporated. May cause irritation to the underlying soft tissue. www.indiandentalacademy.com
    •  Advantages of fixed space maintainer -Bands & crowns are used which require minimum or no tooth preparation -Do not interfere with passive eruption of abutment teeth -Jaw growth is not hampered -The succedaneous permanent teeth are free to erupt in the oral cavity -They can be used in unco-operative patients. -Masticatory function is restored if pontics are placed. www.indiandentalacademy.com
    •  Disadvantages of fixed space maintainer -Elaborate instrumentation with expert skill. -May result in decalcification of tooth material under the bands. -Supra eruption of opposing teeth can take place if pontics are not used. -If pontics are used it can interfere with vertical eruption of abutment of tooth. www.indiandentalacademy.com
