Types of splinting in dentistry: what should you know?

A resting splint holds a wrist, thumb, or finger in a more supported position to reduce irritating movement. A functional splint allows selected movement while protecting a healing area. A dynamic splint uses an elastic or spring-like force to assist movement, while a static-progressive design can be adjusted gradually as motion changes. Thermoplastic splint material is often shaped with heat so it can be moulded to the person’s anatomy. Splinting may be used for carpal tunnel syndrome, cubital tunnel syndrome, De Quervain’s tenosynovitis, or trigger finger when clinically appropriate.

Wear the splint for the schedule provided and keep the skin clean and dry. Check for rubbing, pressure marks, swelling, colour change, numbness, or increasing pain. Do not reshape or tighten it yourself unless the clinician has shown you how. Remove it only as instructed for hygiene or exercises, and keep prescribed movements gentle. A splint is different from fracture casting: a cast is generally intended to provide more continuous immobilisation while a splint may be removed or adjusted.

Contact the therapist or clinician if the support becomes loose, cracks, causes a sore, or no longer fits after swelling changes. Seek prompt care for worsening numbness, a blue or unusually cold finger, severe swelling, or pain that is not settling. A new injury, deformity, or sudden loss of movement may need assessment rather than a replacement splint.

Ask which movement the splint should limit, how long to wear it, which exercises remain safe, how to check skin and circulation, and when the fit should be reviewed.
