Construction of a modified overdenture for patient with cleft lip and palate surgery sequels

Cleft lip and palate are congenital craniofacial malformations caused by the lack of union among those embryonic facial processes responsible for the origin of these structures.1 Lip and palate are formed during the sixth to ninth week of intrauterine embryonic development. Secondary palate develops from lateral palatal prolongations of the fronto-nasal process which fuses to the nasal septum. Lip and palate malformations impinge on respiratory, deglutition, articulation language audition and voice mechanisms of affected patients. These patients frequently sustain sequels which communicate oral and nasal cavities, with resulting facial deformities. The most common treatment would be surgical although there is a prosthetic alternative. Surgical treatment entails several surgical interventions which achieve long term results.

As an alternative, prosthetic rehabilitation can be undertaken. According to the case, rehabilitation might encompass treatment such as removable or fixed prostheses, full dentures, over dentures which might include, when necessary obturator devices.
