PROSTHODONTICS MANAGEMENT OF UNCORRECTED CLEFT LIP – AN INNOVATIVE PROSTHODONTIC APPROACH 1G TASNEEM RAJI 2E ESHONA PEARL 3T SREELAL 4APARNA MOHAN 5GIRI CHANDRAMOHAN ABSTRACT Instances of uncorrected cleft lip in adult or elderly patients are still seen in rural areas or among the people who are unaware of its correction in the developing countries. Adult patients who did not receive proper treatment for cleft lip are challenging for clinicians in terms of prosthetic rehabilitation especially when the patient become edentulous. This paper presents the management and personal identity revival of a completely edentulous 54 year old patient with uncorrected bilateral cleft lip. The facial deformity was characterized by irregularities of upper lip, protruded and rotated central incisors in the pre-maxillary region with multiple missing teeth in the upper jaw and completely edentulous lower jaw. Complete Dentures were inserted following extraction of the central incisors and the remaining natural teeth in the upper jaw, along with a Lip prosthesis made out of silicone that is retained to the maxillary Complete Denture by means of magnets. The patient was very pleased with the improvement in speech and chewing and she approved of her facial esthetics. The existence of uncorrected cleft in the elderly population highlights the need to improve policies in treating patients with cleft lip, mainly in developing countries. INTRODUCTION environmental factors. Some authors, argue that the cleft palate is caused by an alteration in the normal Facial clefts occur along many planes of the face fusion process. They also identify other factors such as a result of faults or defects in development or as a defect in vascular supply to the region involved, maturation of embryonic processes. These anomalies are recognized as oblique and transverse facial clefts, a mechanical alteration in tongue size, intoxication which extend from the upper lip or ala of the nose to with substances such as alcohol, drugs or toxins, and the eye and from the angle of the mouth to the ear, infections or lack of development. In contrast, some respectively. By far the most important of the facial authors attribute it to a serious defect produced by a 2 clefts is cleft lip.
