Introduction: Although the face is only a small part of the human body, it plays an important role in social identity and is one of the main means of interpersonal communication. There are several types of patients who experience their toothlessness with feelings ranging from discomfort to severe disability. Many experience toothlessness as the loss of a body part. Whatever the future needs of the population, the biomechanical and psychological consequences of tooth loss should not be overlooked. In a completely edentulous patient, restoration of the masticatory system is essential. Only a denture with optimal retention and stabilisation will ensure complete patient satisfaction. The retention of a total denture is influenced by anatomical, physiological, physical, mechanical and muscular factors. Purpose: The purpose of this thesis is to describe the fabrication of a total prosthesis using the classical method. The main focus of the fabrication is on the retention mechanisms, stabilisation and statics of the total denture, which allow for a better quality of life of the patient, better eating and speaking, and their adequacy reduces the possibility of irritation and damage to oral tissues. Methods: The thesis includes a review of the literature on total dentures and the mechanisms of total denture retention. The scientific and professional literature was searched in both local and foreign languages. Most of the literature was obtained from PubMed and Google Scholar bibliographic databases. Information was also obtained from the library of the Faculty of Medicine, the Faculty of Medicine and the National and University Library. The literature used was limited to articles published in the last 10 years and some older literature. Results: The method of fabrication of the upper and lower total dentures is similar but not identical. We have tried to follow the principles described in the theoretical part of the thesis using the descriptive method. The process of fabricating a total denture consists of several stages. Discussion and conclusion: Retention and stabilisation must be analysed separately, as they are not synonymous, but only closely related. The conditions for good denture retention may be excellent, but they are not well exploited due to inadequate tooth positioning, shape and size of the base plate. Retention and stabilisation of a total denture can be defined as the use of all factors that contribute to the elimination of anything that tends to move the denture during mastication or relative rest. These factors are adhesion, vacuum, cohesion and salivary viscosity, respectively, and must be analysed individually and in their totality. The fact is that all factors are very important in the retention and stabilisation of total dentures, and success depends largely on the quality of the anatomical and functional impressions.
