1

Q

tooth wear - immediate treatment

A

deal with pain
sensitivity
- desensitising agent
- fluorides
- bonding agents
- GIC coverage of exposed dentine
pulp extirpation
- if wear has compromised pulpal health
smooth sharp edges
- prevents trauma to cheeks and tongue
extraction
- pain from unrestorable/non-functional tooth
TMJ pain
- important in attrition - acute symptoms need to be controlled

Q

tooth wear - initial treatment

A

stabilise existing dentition
treat caries
treat perio condition
oro-mucosal

once you have a diagnosis and identified primary cause:
- establish preventative regime
treatment without prevention will fail

Q

tooth wear - preventative treatment

A

when monitoring identify whether wear is progressing or historic
if active and progressive treatment is required
- includes prevention

Q

tooth wear prevention: abrasion

A

remove foreign object or substance involved
change toothpaste
alter brushing habits
change habits
- nail biting
- wire stripping
- piercing biting
- pen chewing

Q

cervical toothbrush abrasion - preventative treatment

A

simple RMGIC, GIC or composite placed
- RMGIC prefferrd as best survival rate
- does not require tooth preparation
- patient wears through restoration rather than teeth

Q

prevention: attrition

A

more difficult to address
generally related to parafunctional habit
generally centrally mediated response to life stressors
- CBT
- Hypotherapy
splints can be used
- wear away in preference to tooth
- may be habit breaker
- soft splint can be used as diagnostic device
- hard splints more robust and can be used over a longer term

Q

attrition : michigan splint

A

popular type of hard splint
provides ideeal occlusion with even centric stops
has canine rise which provide disclusion in eccentric mandibular movements
- canine guidance

Q

prevention: erosion

A

treatment of erosion should be considered in all wear cases

treatments include:
fluorides
desensitising agents
- not really preventative but relives symptoms
dietary management
habit changes
- swilling drinks around mouth
- drinking from cans - straw recommended
- sports drinks/gels

medical
- construal gastric acid - GORD, reflux, hiatus hernia
- anorexia and bullimia

may require discussion with patients doctor
- consent must be gained to contact GMP
- change in drugs may not be possible

Q

abfraction - prevention

A

assess occlusion on teeth with abfraction lesions
fill cavities with low modulus restorative materials
- RMGIC
- flowable composite

Q

passive management

A

should be the first part of any wear treatment
prevention and monitoring
phase usually lasts for 6 months
many patients - all that is necessary

Q

tooth wear active management

A

intervention threshold
simple restorative intervention
- covering exposed dentine
- filling cupped defects in molars or incisors
more extensive restorations nay be required
- if leads to further complications
- aesthetics have gone beyond patient acceptability

Q

treatment of maxillary anterior tooth wear depends on

A

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

Q

pattern of maxillary anterior tooth wear - classification

A

tooth wear limited to palatal surfaces only
tooth wear involving palatal and incisal edges with reduced clinical crown height
tooth wear limited to labial surfaces

Q

Active management of maxillary incisal tooth wear where there is adequate inter-occlusal space
- give examples of cases where this may be necessary

A

if teeth wear rapidly and there is no alveolar compensation
where there is an AOB
where there is an increased overjet
- available space for restorations with no change in OVD

  • unusual cases

16
Q

Active management of maxillary incisal tooth wear - challenges

A

majority of cases there is no increase in freeway space
compensation for loss of tooth substance by dents-alveolar bone growth
maintains masticatory efficiency
HOWEVER
leaves no space for restorations to be placed

17
Q

How to create space to treat maxillary anterior tooth wear

A

increase OVD
- multiple posterior extra coronal restorations
- downsides - complex, destructive and expensive
occlusal reorganisation from ICP to RCP
- complicated, can be destructive, specialist treatment
surgical crown lengthening
- doesn’t really create more space
elective RCT and post crowns
- very destructive
conventional orthodontics
- lengthy treatment

18
Q

surgical crown lengthening

A

exposes more of the crown for retention of final restoration
repositioning of gingival apically generally with removal of bone
sensitivity
occlusal reduction still required

19
Q

what is the Dahl technique?

A

method of gaining space in cases of localised tooth wear
originally a removable CoCr anterior bite plane
- now carried out in composite (better aesthetics, better compliance, easier to adjust)
covering palatal survives and allowing occlusion on raised cingulum
results in posterior dislcusion and increase in OVD of 2-3 mm
occlusal contacts only on incisor/canine teeth

20
Q

Dahl technique How is spaced gained?

A

over a period of 3-6 months space gained between incisors
anteriors intrude
posteriors erupt
results in space between upper and lower anteriors allowing restoration without need for occlusal reduction

21
Q

Dahl technique - effectiveness

A

variable rate of affect - faster in younger patients
if no movement in 6 months = won’t work
>90% success rate
occlusion initially disorganised but reestablishes with time

22
Q

Dahl technique - contraindications

A

active periodontal disease
TMJ problems
post orthodontics
bisphosphonates
dental implants
existing conventional bridges

23
Q

Dahl technique is the treatment of choice to treat…

A

localised anterior tooth wear
