An obturator is a prosthetic appliance that closes a palatal opening — whether from an unrepaired cleft palate, a residual oronasal fistula after cleft repair, a palatal perforation, or a maxillary resection (oncology). The appliance separates the oral and nasal cavities, restoring the ability to swallow without nasal regurgitation, improving speech (hypernasality is reduced), and restoring palatal support for the tongue. For infants with unrepaired clefts, the obturator (also called a feeding plate — see Acrylic plate retainer) enables feeding before surgical repair. For adults with surgical defects, the obturator is a long-term prosthetic solution. CFL's obturator serves patients referred by orthodontists, oral surgeons, and prosthodontists.
The obturator's acrylic or resin body physically occludes the palatal opening, restoring the physical barrier between oral and nasal cavities. For cleft palate, the obturator seals the cleft while allowing normal intraoral function. Retention is achieved through Adams clasps or ball clasps on adjacent teeth, or through close adaptation of the acrylic margins to the defect edges. For infants, the obturator is designed to be removable for cleaning and to allow feeding with minimal effort.
Unrepaired cleft palate (pre-surgical management); residual oronasal fistula after cleft repair; palatal perforation from trauma or other causes; post-maxillectomy patients requiring prosthetic palatal obturator; patients awaiting surgical repair who need functional rehabilitation; adult patients where surgery is not possible or desired.
Must be updated as the patient grows or the defect changes. Requires good retention on adjacent teeth — extensive edentulism in the defect area makes retention challenging. Not a substitute for surgical repair when surgery is feasible. Hygiene around the appliance and defect edges is critical.

Fabrication requires precise impressions that capture the defect extent — impression technique with cleft palate patients is specialized (risk of material flowing into the nasal cavity). The defect margins must be accurately captured for a well-sealing obturator. CFL offers obturators — a reasonable price point for a specialized prosthetic appliance. Digital workflow (intraoral scan + 3D printed model) simplifies fabrication for accessible defects.
