Simulation-based dental education has been increasingly implemented in dental training. Virtual reality simulators are being explored as an adjunct to dental education. Simulation-based dental education could serve as a powerful aid to preclinical instruction. This article provides an overview of how dental simulators can be used in dental instruction and manual dexterity training, utilizing the Simodont dental trainer as a reference. The Simodont dental trainer provides a platform for students to hone their manual dexterity skills and practice repeatedly prior to conventional clinical simulations. Additionally, it can reduce resource wastage. However, the financial cost of setting up and maintaining the system can be high. The high cost would ultimately limit the number of devices each individual school could afford, as a potential drawback to meeting the training needs of many dental students at one time. The machine’s force-feedback mechanism provides trainees with the tactile experience of drilling into various tissues. Students are empowered via self-learning and assessment, with guidance provided for diagnosis and treatment. From training students on basic operative skills to providing basic aptitude tests for entrance examinations, the Simodont dental trainer’s functions and potential for further development may make it a valuable tool in the field of simulation-based dental education.
Despite global efforts to improve individuals’ oral health, a considerable proportion of patients still progress to the stage in which the extractions of all teeth in one arch or both are indicated. An immediate complete denture remains a relatively accessible treatment option, particularly for those patients who cannot afford or do not need implant treatment. It is often one of the best solutions when the complete extraction of the remaining teeth is unavoidable. The denture is fitted immediately after the surgical clearance of teeth. It acts as a splint for helping with haemostasis, preventing trauma, and promoting wound healing. More importantly, an immediate denture can copy the characteristics of the existing dentition and establishes the vertical dimension of occlusion. It offers immediate replacement of the missing teeth, thereby avoiding a period of edentulism and social embarrassment. These treatments help relieve patient anxiety and bring about patient satisfaction. This study used a case report to illustrate the clinical procedures required for the construction of an immediate complete maxillary denture with good retention, support, stability, and aesthetics.
A well-designed removable partial denture can replace the loss of hard and soft tissues, restore masticatory function and maintain arch integrity. It is relatively simple, noninvasive and economical compared to other treatment options. Removable partial denture is therefore a common option among various treatment replacing missing teeth. A removable partial denture replacing anterior missing teeth can improve esthetics and hence the patient's quality of life. However, metal components of a removable partial denture may be visible and affects patient satisfaction. Esthetics of a removable partial denture can often be improved with some modifications to traditional designs. This article reported the use of a cobaltchromium-based removable partial denture to replace a missing maxillary lateral incisor and molars. Palatal retentive arms were employed as the retentive components on the premolars to avoid the metal component being seen when speaking and smiling. The indications and design of the removable partial dentures with palatal retentive arms are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
