Operativ techniques in Dentistry: Paedodontics and Orthodontics

Transcription

1 Operativ techniques in Dentistry: Paedodontics and Orthodontics The purpose of orthodontics Grouping of the appliances Element of fixed appliances The types and parts of the removable appliances

2 The aim of orthodontic treatments To solve esthetic complains To treat the functional problems (chewing, speech, TMI) Prevention (caries, parodontitis, TMJ dysfunction)

3 Sagittal anomalies - Angle classification (based on:anteroposterior relationship of the jaws) Angle II. distocclusion Angle I: normocclusion) Angle III. mesiocclusion

4 I. class

5

6 Angle I.

7 Angle II. - Distocclusion Angle II/1 Angle II/2

9 Functional jaw orthopaedics, bimaxillary, functional appliances

10 Functional jaw orthopaedics, bimaxillary, functional appliances Restructuring of TMJ Restructuring of dentoalveolar area New muscle balance

11 Bimaxillary appliances - Functional jaw orthopaedics AKTIVATOR

12 Construction bite - set of anteroposterior and vertical relationship

13 Functional jaw orthopaedics Set of vertical relationship Grinding of appliance

14 AKTIVATOR

15 Fixed appliances for the treatment of II. class anomalies Herbst-appliance Jusper Jumper Forsus spring stb.

16 CLASS II MALOCCLUSION FUNCTIONAL APPLIANCES PERMANENT DENTITION CLASS II DIVISION 1 HERBST APPLIANCE (FIXED) MANDIBLE HELD IN PROTRUSION + OPEN VERTICALLY

19 II. Class rubbers

20 Extrakció nélkül normálokklúzió beállítása Headger and fixed appliance If the maxilla is responsible for the anomaly and in mild distalocclusion Distalisation of upper molars Prohibition of growing of upper jaw

21 HEADGER Headgear Anchorage Distalisation of molars Treatment of vertical anomalies

22 Extraction of upper premolars (compromised treatment)

27 Angle III progenie - mesiocclusion

28 Orthodontic treatment in primary dentition Progenia 1.appliance: chin cap 2. Inclined plane (against frontal crossbite)

29 Angle III progenie - mesiocclusion

30 Angle III progenie - mesiocclusion

31 CLASS III MALOCCLUSION PROTRACTION of the maxilla FACE MASK (DENTAL + SKELETAL) FULL FIXED APPLIANCES CLASS III ELASTICS

32 Premolar extractions III.class Assimmetric anomaly

33 Vertical anomalies Deepbite Open bite (sceletal or dentoalveolar?)

34 Bite raising plane (on the upper appliance)

35 Bite raising plane PLANE

36 Bimaxillary, functional appliances Frankel- appliance

37 Anti Spee (curve) wires

38 Open bite Consequences of thumb sucking Open bite Protrusion of upper incisors Retrusion of lower incisors - Distalocclusion

39 DEGLUTITIO INFANTILIS Tongue thrust swallow

40 5- Intermaxillary rubbers, miniimplant Bite closure
