# Investigation on the Application of Artificial Intelligence in Prostodontics
## 1 Introduction  
Prosthodontics is a branch of dentistry that is considered both an art and a science. It is the art and science of diagnosing, planning, rehabilitating, and preserving the function, comfort, appearance, and health of the oral structures of patients with clinical problems caused by missing or deficient teeth and oral and maxillofacial tissues. It fulfils this purpose mostly by replacing missing teeth and associated structures with artificial ones [1; 2; 3; 4; 5; 6; 7]. Prosthodonics focuses on the treatment and construction of removable and fixed dental prostheses, as well as the preparation of finishing margins along the tooth for better extension and fitting of the crowns, implant surgery, and the construction of a maxillofacial prosthesis. It is also used to develop and maintain the relationship between the upper and lower jaws for a stable prosthesis [8; 9; 10]. AI can be very helpful in many different kinds of therapy. Prosthodontics, or the study of dental prostheses, is an important subject that has a broad influence on different phases of a dentist's life. Advancements in digital dentistrypositively influenced prosthodontics and led to exponential development in the field of materials used, diagnosis and treatment planning, and even in prosthesis fabrication. Several factors can contribute to the fabrication of dental prostheses. First, it was suggested that the deterioration in dental morphology poses a threat to a person's physical, mental, and behavioral health [1; 2]. Due to difficulty in biting (or breaking down food), the patient starts shifting the food choices to a softer one or even try to avoid food. Second, tooth loss makes people more isolated because of concerns regarding social approval [3]. Arguably, having beautiful teeth helps you socialize more since people generally want their entire body to look good. Finally, having a tooth in the oral cavity helps to keep the tongue, lips, and cheeks in the right positions, giving the facial features a proper shape [4]. In prosthodontics, the replacement of missing teeth is possible with the help of implants and crowns [5; 6; 7; 8; 9; 10]. Advancements in digital dentistry positively influenced prosthodontics and led to exponential development in the field of materials used, diagnosis and treatment planning, and even in prosthesis fabrication. Several factors can contribute to the fabrication of dental prostheses. When there is a loss of teeth, the construction of prostheses such as removable partial dentures, fixed dental prosthesis or implants provides an alternative [11; 12; 13]. The type of implant utilized, and the health of the remaining residual alveolar ridge, determine how rehabilitation can be carried out. Multiple techniques are required during this rehabilitative procedure [14; 15]. Artificial intelligence (AI) applications are widely used in digitized daily life [16; 17; 18; 19], such as in the form of online companions such as \"Alexa\" or \"Siri\", and they are used in many technical disciplines. AI algorithms are widely used in the medical field to analyze images by extracting features and performing target studies [20; 21]. Over the past five years, there was an increase in studies on the usefulness and use of AI in radiology to enhance workflow and alleviate some of the radiologist's workload. Although dental technology is improving, it is still behind medical technology [22; 23; 24; 25; 26; 27; 28; 29; 30; 31]. In conventional treatment, standardized digital dental methods are used. The desktop design and CAD/CAM fabrication became standard in healthcare and labs. AI application is a new concept that is starting to emerge as dental digitization advances [32]. Dentures for defendulous patients are difficult to create because of the high aesthetic and functional criteria that must be satisfied. The CAD/CAM software's machine learning can realign the teeth to restore the inter-maximillary connections.
