Background:
A common form of self-injurious behavior (SIB) involves self-inflicted injury to the lips. The available published literature offers limited noninvasive treatment options that produce predictable and successful outcomes without surgery.
Objective:
This case report aims to illustrate the conservative management and rehabilitation of a patient exhibiting SIB through lip-biting. The treatment utilized an innovative, removable acrylic splint, named the "Noninvasive intraoral acrylic appliance" (NIINAA).
Methodology:
The NIINAA was custom-built using auto-polymerizing acrylic resin. The patient was instructed on its use, and modifications to the appliance's design were made based on the patient's feedback during subsequent follow-up visits.
Results:
Follow-up appointments conducted at one week, 15 days, and 4 weeks showed successful healing, effective rehabilitation, and strong patient compliance. The patient indicated a marked improvement in their primary complaint, as measured by a visual analog scale (VAS). The treatment demonstrated high adherence and tolerance with no significant adverse effects noted.
Conclusion:
A conservative approach using the NIINAA device successfully established patient rehabilitation without requiring invasive surgical procedures. This method underscores the importance of preserving teeth and surrounding oral structures in patients with SIB through non-surgical interventions.
