Advanced periodontal disease often compromises the tissues supporting the teeth, causing an increase in their mobility or migration. A-splint is an appliance for the immobilization or stabilization of diseased parts. The use of splinting in periodontal therapy is controversial. There is little evidence to support the much quoted rationale that the splinting of mobile teeth enhances resistance to further periodontal breakdown and improves the healing response. Splints shold be use only if it is necessary for obtaining occlusal stability or for replacing missing teeth, nor dose it predictably reduce mobility.
The two major indications for periodontal splinting are to immobilize excessively mobile teeth so that the patient can chew more comfortably, and to stabilize teeth in their new position after orthodontic treatment.
In this paper of advanced periodontal patient after orthodontic treatment on upper anterior teeth, we carried out the splinting in maxillary anterior tooth by use of multi-purpose tooth splinting material [Wing Rock] system (Daigen, Osaka) .
The [Wing Rock] system uses shape memory alloys which have many advantages a splinting use of resin-wire or prosthesis.
Consequently, we could accomplish the improvement of esthetics, tooth mobility, and appropriate mandibular movement on the maxillary anterior tooth.
