Speech aid prosthesis, adult

Synonymous terminology: prosthetic speech appliance, speech aid, speech bulb. A definitive prosthesis, which can improve speech in adult cleft palate patients either by obturating (sealing off) a palatal cleft or fistula, or occasionally by assisting an incompetent soft palate. Both mechanisms are necessary to achieve velopharyngeal competency. Generally, this prosthesis is fabricated when no further growth is anticipated and the objective is to achieve long-term use. Hence, more precise materials and techniques are utilized. Occasionally such procedures are accomplished in conjunction with precision attachments in crown work undertaken on some or all maxillary teeth to achieve improved aesthetics.
