3. SPLINTING DEFINITION: It is defined as the joining of two or more teeth into a rigid unit by means of a fixed removable restorations/devices. Splint by definition is an appliance used for immobilization of injured or diseased parts.

4. OBJECTIVES Provides rest For redirection and redistribution of forces To preserve arch integrity Restoration of functional stability To stabilize mobile teeth during surgical, especially regenerative therapy To prevent supra-eruption

5. IDEAL REQUIREMENTS OF A SPLINT

6. CLASSIFICATION OF SPLINTS ACCORDING TO THE PERIOD OF STABILIZATION: Te mporary Permanent Provisional ACCORDING TO THE TYPE OF MATERIAL: Bonded, Composite resin button Braided wire A-splints ACCORDING TO LOCATION ON THE TOOTH: 1.INTRA-CORONAL: 2.EXTRA-CORONAL: Composite resin with wire Tooth bonded plastic Inlays Night guard Nylon wire Welded bands

7. VARIOUS COMMONLY USED SPLINTS: Splints for Anterior teeth- a)Direct bonding system using acid etch technique and a light cured resin b)Intra-coronal wire and acrylic wire resin splint Splints for Posterior teeth- a)Intra-coronal amalgam wire splints b)Bite-guards c)Rigid occlusal splint d)Composite splint

8. PRINCIPLES OF SPLINTING 1. Inclusion of sufficient number of healthy teeth 2. Splint around the arch 3. Coronoplasty may be performed to relieve traumatic occlusion 4. The splint should be fabricated in such a way so as to facilitate plaque control 5. Splint should be aesthetically acceptable and should not interfere with occlusion

9. INDICATIONS Moderate to advanced tooth mobility which has not responded to periodontal therapy and occlusal adjustments When it interferes with normal masticatory function Facilitates scaling and surgical procedures After orthodontic treatment After acute dental trauma eg : subluxation, avulsion etc… CONTRAINDICATIONS Moderate to severe tooth mobility in the presence of periodontal inflammation / primary occlusal trauma Insufficient no. of firm or sufficiently firm teeth to stabilize the mobile teeth Prior occlusal adjustment has not been done on teeth with occlusal trauma Poor oral hygiene

10. ADVANTAGES May establish final stability and comfort for patient with occlusal trauma Helpful to decrease mobility and accelerate healing following acute trauma to teeth Allows remodelling of alveolar bone and periodontal ligament for orthodontically splinted teeth Helpful in decreasing mobility thereby favouring regenerative therapy Distributes occlusal forces over a wide area DISADVANTAGES All the splints hamper patient’s self care Accumulation of plaque at the splint margins can lead to further periodontal breakdown in a patient with already compromised periodontium Development of caries
