“…21 From 1945 to 1992 approximately, several studies still used the term microforms, in a way similar to its use by Mengele, to refer to dental malformations, cleft palate, and cleft uvula. 34,35 In the last 30 years, many studies [36][37][38] have actually used microforms exclusively to describe very small clefts of the upper lip. Small, but not very small, malformations are often distinguished with the term mini -microform cleft.…”

Introduction The early geneticist and psychiatrist Ernst Rüdin (1874–1952) became one of the key figures in the eugenics movement and in the German health system of the Nazi era. His connections in the international eugenics network have played an important role in the history of eugenics. Objective To discuss the connections between Ernst Rüdin's scientific group in Munich and Otmar von Verschuer's group in Frankfurt during the Nazi era. Methods Otorhinolaryngological materials from Ernst Rüdin's former private library are presented, and they show Rüdin's deep involvement in the international eugenics network. These materials provide insights into early medical genetics in otorhinolaryngology. Results One result of the present study is that eugenics groups from Munich, Frankfurt, and New York certainly influenced one another in the field of otorhinolaryngology. Karlheinz Idelberger and Josef Mengele were two scientists who performed hereditary research on orofacial clefts. Later, Mengele became deeply involved in Nazi medical crimes. His former work on orofacial clefts clearly had, to some extent, an influence on subsequent studies. Conclusion An international eugenics network already existed before 1933. However, it becomes clear that the weaknesses of many early genetic studies did not enable its authors to draw firm scientific conclusions, suggesting that scientists lacked an accurate concept of the genetic causes of most illnesses.

“…9 Obturators with metal frame are made with consideration for comfort and strength because the obturator also functions to support the dentures that replace the missing anterior and posterior teeth that receive a large masticatory load. 12 The basic principles in constructing a definitive obturator depend on the condition of the defect and which provides the greatest benefit in function and comfort. 13 Consideration must be given to the size and location of the defect, the number and position of the remaining teeth, and the distribution of the maximum load to support the obturator.…”

A 42-year-old woman was referred to the Department of Prosthodontics, Hasanuddin University Dental Hospital with speech, swallowing and chewing difficulties caused by a fractured and non-reusable acrylic obturator. The patient had been using the obturator since maxillary tumor resection in 2012, which resulted in a significant and deep defect in the right maxillary region. Intraoral examination revealed a defect in the midline of the palate that extended to the left alveolar bone, and 21, 22, 23, 24, 25, 26, 27, 16 were edentulous. The maxillary defect did not appear inflamed or infected, and the surrounding area appeared normal. The treatment plan was fabrication of a maxillofacial skeletal partial denture to rehabilitate the maxillary defect. Primary impressions were made with irreversible hydrocolloid ma-terial with a stock tray to obtain a study model. Custom tray was made for individual impressions with polyvinyl si-loxane material to obtain working models. A survey was conducted, and framework and bite rim were made. Maxil-lary denture was designed with Akers clasps at 35, 37, RPI at 45, full palatal palate as main connector. The denture framework was tried on, followed by determination of vertical dimensions. Denture alignment was done in the articu-lator using A3 color. The was prostheses were tried in and evaluated of retention, articulation, phonetics, and aes-thetics; then sent to dental laboratory for processing and the obturator was then inserted into the patient's mouth. Pati-ent follow-up was scheduled 24 hours and 1 week after insertion. It is concluded that the maxillofacial partial den-ture is a rehabilitation device that can result in decent retention and stabilization, especially in cases of acquired de-fects. The prosthesis can improve patient adaptation and ability with speech, mastication and swallowing functions.

“…Making a definitive obturator with the hollow bulb technique which is extended into the defect, in addition to closing the defect, the prosthesis will be lighter and can increase the retention and stability of the prosthesis. [6][7][8] The definitive obturator was placed two months after using the interim obturator. The requirements for inserting a hollow bulb obturator must meet 3 three objectives, namely 1) forms a good seal to make the function of swallowing and speaking effective; 2) provides retention support and stability.…”

“…6 There are three stages of obturator insertion for surgical defects with different time, namely surgery obturator (made before surgery and inserted immediately after surgery in the operating room), intermediate obturator (made and inserted 2 weeks after surgery), and definitive obturator (made and inserted 3-4 months after surgery). 3,7 In this case report, a definitive obturator was made and inserted for a patient who had previously used an intermediate obturator which can restore the mastication, swallowing of food and drink, speech, aesthetic and psychological functions.…”

Background: Obturator is a prosthesis to replace tissue lost post tumor surgery in the maxilla called maxillectomy. Obturator is made of acrylic and consists of surgery, intermediate, and definitive obturator. Definitive obturator is made using Hollow bulb technique to be light and stable when used. In this case, a definitive obturator was made for a patient using intermediate obturator. Objectives: To inform that obturator can rehabilitate maxillary defect to restore the patient’s mastication, digestive, phonetic, aesthetic and psyche functions. Case report: A 28-year-old man came for postoperative cleft management. Diagnosis is Post OP Hemi maxillectomy Dextra. The procedure begins with impression to obtain study model and the making of individual tray. The next visit is grinding the remaining teeth for occlusal rest placement. Double impression is done to obtain working model and making the bite block. The third visit is bite block try-in on the patient and placed to working model for fixation on the articulator, followed by tooth color determination and laboratory instructions. The fourth visit is wax obturator try-in and checking occlusion, articulation, aesthetics and phonetics. The fifth visit is definitive obturator insertion and follow up. Conclusion: Definitive obturator can rehabilitate defects post maxillary tumor surgery.Keywords: Maxillary defect, definitive obturator, Hollow bulb technique
