C.R.I

2. WHAT IS SPLINT..???
It is defined as rigid or flexible device that
maintains in position of a displaced or movable part
, also used to keep in place and protect an injured
part.
Splinting in dentistry ..??
“the joining of 2 or more teeth into a rigid
unit by means of fixed or removable
restorations or devices.

3. History..!!!
A Phoenician mandible from 500BC found in modern day
Lebanon which has two carved ivory teeth attached to four
natural teeth by gold wire.
Obin and Arvin's (1951) -self curing internal splint.
Harrington(1957) modified the splint by incorporating
cemented stainless steel wire.

4. Ward & Weinberg (1961) – developed new techniques using
a plastic matrix or using wire reinforcement.
Splints have thus come a far way to INTRACORONAL
BONDABLE FIBER SPLINTING of the present.

5. Should reduce movement 3 dimensionally
Centre of rotation of the affected teeth must be
located in the remaining supporting bone.
No inflammation
Minimum one third of bone support remaining.
Should allow for oral hygiene methods
Should not irritate soft tissues.
principles

6. objectives
 To provide rest
 For redirection of forces
 For redistribution of forces
 To preserve arch integrity

7. CONTINUE…
 Restore of functional stability
 Psychological well being
 To stabilize mobile teeth during surgery , especially
during regenerative therapy
 To prevent the eruption of unopposed teeth

8. Indications
 To stabilize moderate to advance tooth mobility, that cannot be reduced
by other means that has not responded to occlusal adjustment and
periodontal therapy.
 Stabilize teeth in secondary occlusal trauma
 Stabilize teeth with increased mobility which interfere with normal
masticatory function
 Facilitate scaling and surgical procedures.
 Prevent tipping & drifting of teeth.
 Prevent extrusion of unopposed teeth.
 Stabilize teeth after acute dental trauma i.e. .sub luxation , avulsion.etc.

9. CONTRA INDICATIONS
 Moderate to severe tooth mobility in the presence of periodontal inflammation
& or primary occlusal trauma
 Insufficient number of firm/ sufficient firm teeth to stabilize mobile teeth.
 Prior occlusal adjustment has not been done on teeth with occlusal trauma or
interferences.
 Patient not maintaining oral hygiene.
 When the sole objective of splinting is to decrease tooth mobility following the
removal of splint.

10. classification
 According to the period of stabilization
 According to the type of material
 According to the location on the tooth

11. ACCORDING TO THE PERIOD OF STABILIZATION
Temporary stabilization (worn for less than 6 months)
Removable fixed
• Occlusal splint with wire
• Hawley with splinting arch wire
Intra coronal Extra coronal
• Ss wire with resins
• Wire & resin with & acid etching
• Enamel etching & composite
resin
• Ortho soldered bands
• Brackets& wire
• Amalgam
• Amalgam & wire
• Amalgam , wire, resin
• Composite, resin, wire

12. PROVISIONAL STABILZATION
• To be used for months up to several years e.g. acrylic splints,
metal band
• permanent splints ; used definitely
Removable / fixed • Extra / Intra coronal
• Full / Partial veneer crowns
soldered together
• Inlay / Onlay soldered together

13. ACCORDING TO THE TYPE OF
MATERIAL
• Bonded composite resin button splint.
• Braided wire splint.
• A- SPLINTS

14. ACCORDING TO THE LOCATION ON THE TOOTH
Intra coronal Extra coronal
• Tooth bonded plastic
• Night guard
• Welded bands
• Composite resin with wire
• Inlays
• Nylon wire

15. COMMONLY USED SPLINTS
• Splinting for anterior teeth
• Splinting of posterior teeth
Direct bonding system
Intra coronal wire
Acrylic wire resin splint
Intra coronal amalgam wire splints
Bite guard
Rigid occlusal splint
Composite splint

16. Splinting of anterior teeth

17. Splintee
Tooth that needs support
Splinters
Adjacent teeth that provide support.

18. Direct bonding system
Acid etching Bonding agent
Composite curing

19. INTRA CORONAL WIRE SPLINT
Slot preparation Ss wire adapted into the slot
Sealed with resin

20. VARIATION OF THE “A” SPLINT
 A 1mm deep M / D box is
prepared parallel to the long
axis of tooth
 SnF/CA(OH)2 varnish is applies
& threaded pin is then placed.
 Ss is wire is adapted around
the pin .

21. SPLINTING FOR
POSTERIOR TEETH

22. INTRA CORONAL AMALGAM WIRE
SPLINTS

23. BITE(NIGHT) GUARD
 Bruxism with occlusal wear
 Primary or secondary occlusal traumatism.
 Anterior open bite with trauma.
 Impinging over bite with periodontal involvement.
 Following orthodontic treatment.( as retainer).

24. RIGID OCCLUSAL
SPLINT
 Head & neck pain as a result of muscle
spasm is usually treated with maxillary
occlusal splint.
 Rigid & covers all occlusal surfaces.
 Designed such that all opposing teeth
contact the splint in centric relations.

25. FIBER REINFORCED SPLINTING
Fibre reinforced splinting

26. PROCEDURE
Coronoplasty Acid etching
Flowable composite

27.  It have good flexural strength and do
not require mechanical retention.
 Faster & easier technique.
 Superior in all properties compared
to all other splinters.
Composite curing
Post operative

28. Strength
• May establish final stability & comfort for patient with
occlusal trauma.
• Helpful to decrease mobility and accelerate healing
following acute trauma to the teeth.
• Allows remodelling of alveolar bone and PDL for
orthodontically , splinted teeth.
• Helpful in decreasing mobility favouring regenerative
therapy.
• Distributes occlusal forces over a wider area.

29. Weakness
Hygienic
Mechanical
Biological
