16
Q

when should passive management be done

A

first part of any treatment of wear and lasts for 6 months

17
Q

what is active management

A

intervention threshold

18
Q

what is simple restorative intervention

A

cover exposed dentine
fill cupped defects

19
Q

when do you use extensive restorative intervention

A

wear leading to further complications, aesthetics, bad prognosis

20
Q

what 5 things does maxillary anterior management depend on

A

pattern of tooth wear
inter-occlusal space
space required for restorations being planned
quality and quantity of remaining tooth tissue particularly enamel
aesthetic demands of the patient

21
Q

how do you manage maxillary wear

A

composite resin

22
Q

what gives adequate inter-incisal space

A

rapid tooth wear
AOB
increased overjet

23
Q

what is dento-alveolar compensation

A

where the bone grows to maintain mastication but you cannot get a restoration in

24
Q

what are the problems with creating space for traditional restorations

A

little tooth tissue to begin with
poor retention due to short axial walls
good chance of pulpal damage due to short clinical crowns
new materials offer better more conservative approach in these cases

25
Q

how can you make space for restorations

A

increase OVD with posterior extra-coronal restorations
occlusal reorganisation from ICP to RCP
surgical crown lengthening
effective RCT
conventional orthodontics

26
Q

what are the effects of surgical crown lengthening

A

expose more crown
reposition gingiva apically
removal of bone
sensitivity increased

27
Q

what is the Dahl technique

A

method of gaining space in localised wear
use composite as anterior bite plane covering palatal surfaces resulting in posterior open bite where posterior teeth will then erupt and give OVD increase by 2-3mm

28
Q

how long does the patient need to use the dahl technique for

A

3-6 months

29
Q

who is the Dahl technique not suitable for

A

active perio disease
TMJ patients
post orthodontics
bisphosphonates
dental implants
existing conventional bridges

30
Q

what is the technique of choice for localised anterior tooth wear

A

dahl technique
