PREPROSTHETIC PREPARATIONS EDENTULUS AT BAMAKO CHU-CNOS

Oral health and general health are closely linked and dependent in humans. The total disappearance of teeth leads to the loss of proprioceptive control systems, the modification of the entire tissue system and therefore great psychological fragility. Pre-prosthetic surgery consists of restoring the osteo-mucosal tissues to allow the installation of a prosthesis. The objective: was to assess the need for pre-surgical prosthetic preparation for the totally edentulous at the CHU-CNOS of Bamako. Method and materials: This was a prospective, descriptive study extending over a period of 8 months (from January 1 to August 31, 2021). Patients seen at the removable prosthesis service for a consultation in whom a diagnosis of edentulism was made constituted the study population. We carried out an exhaustive recruitment of totally edentulous people received at the service for the completed removable prosthesis who agreed to participate in the study. The data were collected using an individual survey form and analyzed with SPSS version 20.0 software. Result: A total of 50 patients were registered, including 14 men or 28% and 36 women or 72%. The sex ratio was 0.38 in favor of women. The 60 to 69 age group was the most represented with 19% and the average age was 56 years. The demand for prosthetic restoration for aesthetic and functional purposes represented the reasons for consultation in 46%, 44% of cases and pain in 10% of cases the most expressed concern by patients. Oral hygiene was average 64%, good at 20% and poor at 16%. Tooth extraction represented 70% of cases, without surgery 20% of cases and osteotomy 10% of cases as pre-surgical prosthetic treatment. The ridge was poorly resorbed at 40%, moderately resorbed at 30%, very resorbed at 20% and the ridge was negative at 10%, 50% of patients did not wear a prosthesis, 34% of patients wore partial removable prostheses and 16% wore removable total prostheses. Among our patients 66% had normal frenulums, 22% had short frenulums and 12% had wide frenulums. Conclusion: This study made it possible to highlight the real needs in pre-surgical prosthetic preparation. Among these needs, multiple tooth extraction remains the most common pre-prosthetic surgical procedure.
