3. Splints
A rigid or flexible device that maintains in
position of a displaced or movable part;
also used to protect and assists in
stabilization and immobilization of an
injured part.
4. Uses
1. Diagnostic: Occluso-muscle disorders.
2. Stable occlusal: alter neuromuscular reflex ---improve muscle
pain.
3. Occlusal condition: allows the condyles to assume CR.
4. Protect the teeth from abnormal forces.
5. Repositioning the disk: anterior repositioning splint.
9. B] FIXED SPLINTS
1. Metal Cap Splints
2. EDENTULOUS SPLINTS
1. Gunning Splints
2. Kingsley Splints
10. 1] A. DENTULOUS – REMOVABLE SPLINTS :
- LABIOLINGUAL SPLINTS:
This type is used when the patient is dentulous or partially
edentulous to aid in treatment of fractures without or with
minimum
displacement.
11. Labio lingual splint
3 sections one on the lingual side
and two sections in the Buccal side
one RT and one LF
12. Indications: - it can be used for immobilization for
both dentulous or partially edentulous patients.-it can
be used for single arch fixation without displacement of
the fracture lines.
13. Advantages of labiolingual splint: constructed
from radiolucent material so no interference with follow
up x-rays. Well tolerated by the patient, occlusal surface
not coved so could check occlusion Oral hygiene can be
maintained through its use. Quick and easy constructed, it
could be removed in any time to check the fracture healing
and can be fixed again.
14. Types:
A-Acrylic labiolingual splint
B-Cast metal labiolingual splint: could be used in long
duration fixation , thinner than acrylic one, it could be used
with bone graiting, jaw resection
An acrylic band fits around the labiobuccal surfaces as
well as the lingual aspects and a stainless steel wire
connects the two acrylic portions, the wire acts as a
hinge
15. 1] A. DENTULOUS – REMOVABLE
SPLINTS :
ii) FENESTRATED SPLINTS :
This splint is utilized primarily when there are
deciduous teeth or when the clinical crowns are not
available.
It is constructed in an one-piece acrylic to fit the
dentition through fenestrations in the occlusal surfaces.
16. 1] A. DENTULOUS – REMOVABLE SPLINTS
:
iii) LINGUAL SPLINTS :
Lingual splint is useful in parasymphyseal fractures of the
mandible to prevent the adverse muscular forces - causing
lingual collapse and
overlap of the fractured segments.
Sufficiently rigid and stabilizes jaw fragments,
used for -6 weeks
17. 1] A. DENTULOUS – REMOVABLE SPLINTS
:
iv) OCCLUSAL SPLINTS/ BITE GUARDS :
The occlusal wafer is generally used for intermaxillary fixation
of fully
dentulous patients who have poor or defective occlusion.
A custom-fabricated acrylic device that fits over the occlusal and
incisal surfaces of either the maxillary or mandibular teeth.
18. ADVANTAGES :
Occlusal appliance therapy is that the treatment is reversible
and
noninvasive
INDICATIONS :
1. Symptoms of temporomandibular dysfunction (TMD)
2. Reduces the frequency of RMMA and sleep bruxism
3. Prevent tissue damage (e.g., tooth wear or chipping)
4. For obstructive sleep apnea – reduces aggravation of

21. 1] B. DENTULOUS – FIXED SPLINTS :
i) METAL CAP SPLINTS15 :
These are metallic cap that covers the whole occlusal segments,
used
in multiple fractures of sphenoid, zygoma, orbital floor and mandible
unable to receive surgical treatment for reduction and fixation of
fractured segments.
22. currently rarely used, it consist of metal crowns covering the
occlusal surfaces buccally and lingually of the teeth on the either
sides of the fracture, it provide efficient rigid fixation and
immobilization.
Types: One piece metal cap splint
Two pieces metal cap splints.
Connected by metal bar with screws to adjust the displaced parts.
24. 2] EDENTULOUS SPLINTS :
i) GUNNING SPLINTS :
An acrylic device used to immobilize the edentulous jaws in occlusion
and to hold together fractured segments of mandibular or maxillary
bones
TYPES :
• One piece gunning splint.
• Two piece gunning splint.
• Sectional gunning splint
25. A. ONE PIECE GUNNING SPLINT:
It is constructed for both arches as one
piece.
Disadvantage - overworked, difficult
to manipulate and cannot be wired to the
jawbones
26. B. TWO PIECE GUNNING SPLINT :
Two separate splints with V-shaped
grooves on the occlusal surface of one arch
and projections to fit these grooves on the
opposite arch gives better results
27. C. SECTIONAL GUNNING SPLINT :
Designed for immediate immobilization of the resected mandible to
minimize postsurgical deviation. It is basically a two-piece gunning
splint and a locking mechanism for immobilization.
28. D. MODIFIED GUNNING SPLINT :
A modified gunning splint may be produced
by altering existing complete dentures or by
repairing and altering fractured complete
dentures. It is similar to the two-piece
Gunning splint..
29. ii)KINGLSEY SPLINTS :
Modified stock tray in emergency of fractured maxilla or
cast metal splint for long term treatments .
May be designed to fit dentulous or edentulous patient.
