Cleft lips and palates are congenital anomalies affecting the mouth and face. For fully edentulous patients with a cleft palate, crafting complete dentures is particularly challenging. These dentures, which incorporate an obturator and extend into the palate, must be meticulously designed to address issues related to appearance, speech, swallowing, and chewing. Treatment for cleft lip and palate aims to restore function, speech, and aesthetics through the use of fixed prostheses, removable prostheses, and implants. The approach should follow key principles of oral rehabilitation, including maintaining proper physiology, stability, aesthetics, hygiene, and considering patient expectations. To ensure the durability of prosthetic solutions, it is crucial to respect both the periodontal and dental tissues and the biomechanics of the prosthesis. Palatogram is an effective and straightforward technique for assessing and verifying palatal contours, which helps in addressing speech deficiencies related to affected sounds. Managing completely edentulous adults with cleft palates, particularly those who have not undergone surgical intervention, presents a significant challenge for prosthodontists. This case report explores the use of a conventional complete denture for a cleft palate patient, utilizing the palatogram technique to precisely record the palatal contours, the neutral zone technique to optimize denture stability by aligning forces in harmony with oral musculature, and monoplane teeth to reduce lateral forces and enhance denture stability. Together, these techniques aim to improve speech, mastication, and comfort, providing a functional and aesthetic prosthesis suited to the patient’s unique anatomical needs. This case demonstrates the successful rehabilitation of an edentulous cleft palate patient using a conventional complete denture with specialized techniques to address the unique anatomical and functional challenges presented. The neutral zone technique, monoplane teeth arrangement, and palatogram technique were crucial in achieving a stable, functional, and aesthetically pleasing denture. These methods helped optimize denture retention and stability, improve phonetics, and enhance masticatory efficiency, providing the patient with a significant improvement in quality of life and self-confidence. For patients unable to pursue more invasive and costly implant-supported options, such techniques offer a viable and effective solution for complete denture fabrication, allowing for functional and aesthetic rehabilitation within economical constraints.
