Patients may face functional, aesthetic, and social distress because of the palatal defects. Prosthetic rehabilitation of maxillectomy or developmental defect can be challenging for prosthodontists. Prognosis of the prosthetic appliances can be affected not only by patients' own ability to adapt to the prosthesis but also by the factors like the remaining teeth, bony structure, and existing mucosa. Maxillary defects are usually developed by surgical intercession of the benign or malignant conditions and trauma cases. Speech, mastication and aesthetics can be hampered by any extent of palatal defect. During obturation of palatal/maxillectomy defects, the primary intent of the prosthodontist should be the shutting of the maxillectomy defect and parting of the oral cavity from the sinonasal openings by use of different bulb designs. In the present case, dentogenic concept has been applied while fabricating the two-piece hollow bulb obturator for restoration of the defect. Well known fact about the gravitational force is that it acts on maxillary obturator and reduces its retentive qualities, this can be counteracted to some extent by making the obturator hollow. Dentogenic concept is the skill, training, and procedure of generating the chimera of natural teeth in artificial teeth during prosthodontic restorations.

Background: Keratocystic odontogenic tumours (KCOT) are benign neoplasia of dentogenic origin and have a high relapse rate. Various invasive treatment methods (decompression, marsupialisation, enucleation, enucleation with adjunctive therapy such as scraping out of the bone cavity, Carnoy's solution or cryotherapy, mandibular resection) have been described for the treatment of KCOT. There is no common opinion on the best kind of treatment.

Unlabelled: The dynesthetic and dentogenic concept, when applied, provides a more natural, harmonious prosthesis, which not only is desired by patients, but also is a quality of care they deserve. Outstanding esthetics can be achieved by simple guidelines, using tooth molds specifically sculpted for males and females, arranging prosthetic teeth to correspond with personality and age and sculpting the matrix (visible denture base) with more natural contours. There is no reason for edentulous individuals to be provided with care of any less quality than that available with other procedures, such as crowns, bridges, veneers, or implant restorations.
