Interdisciplinary approach to tongue thrust habit and partial edentulism in a pediatric patient: A case report

Introduction: Premature loss of permanent teeth in children, often due to severe caries, can significantly impact oral function, aesthetics, speech, and psychosocial well-being. One of the common resulting complications is the development of a tongue thrusting habit, which can further disrupt occlusion and oral development. 

Case History: This case report presents a 10-year-old girl who experienced partial edentulism following the extraction of six permanent teeth under general anesthesia due to massive caries and infection. Clinical findings revealed multiple diastemas, anterior protrusion, and a confirmed tongue thrusting habit. 

Discussion: An interdisciplinary treatment approach was implemented using a modified fixed partial denture with a palatal crib in the maxilla and a removable partial denture with a labial bow in the mandible. The palatal crib served to intercept the tongue thrusting habit, while the prosthetic appliances restored function and aesthetics. After three months, habit cessation was confirmed, allowing removal of the palatal crib and labial bow, with the remaining appliances functioning solely as partial dentures. This hybrid prosthetic strategy successfully addressed both the functional and behavioral issues. The case highlights the importance of early diagnosis and a tailored, multidisciplinary intervention for children with complex dental conditions. 

Conclusion: Modified partial dentures combined with a palatal crib offer a practical, effective solution for managing tongue thrusting and partial edentulism in growing children, promoting oral health, function, and aesthetic development.
