TL;DR: Kennedy’s class III partially edentulous arches were the most prevalent type of edentulism with periodontal disease as major etiology and it was seen that people with medium socio-economic status were more affected by tooth loss.
Abstract: Background: Partial edentulism is the state of loss of one or more but not all natural teeth. Edentulism can affect the esthetics of an individual and can have a negative psychological impact. Recording the frequency of partial edentulism and its nature along with its association with different socio-demographic parameters helps to plan the treatment need and goals of the population in that locality. This cross-sectional study was conducted to find out the frequency of partial edentulism among the patients visiting the dental college of BPKIHS and its teaching district hospitals. Methods: Two hundred partially edentulous patients were selected from four hospitals by purposive sampling and their socio-demographic parameters recorded. Intra-oral examination was done to classify partial edentulous spaces according to the Kennedy-Applegate system. Data was analyzed in SPSS version 11.5 and chi-square test was used to determine the association between independent (age-group, gender, socioeconomic status) and dependent variables (number of missing teeth). Results: In both the arches, Kennedy’s class III was the most prevalent type of edentulism. In the maxillary arch, 44.5% had Kennedy’s class III edentulism whereas in the mandibular arch 34.5% had Class III. Kennedy’s class IV was least common (4% in maxillary arch and 6.5% in mandibular arch). Forty-five partially edentulous patients above 50 years of age had ≥ 4 teeth missing and 140 were from medium socio-economic status. Conclusion: Kennedy’s class III partially edentulous arches were the most prevalent type of edentulousness with periodontal disease as major etiology. It was also seen that people with medium socio-economic status were more affected by tooth loss.

TL;DR: Altered cast technique is the best alternative technique in case of distal extension cases because better tissue adaptability, proper extension of denture base, equal stress distribution, better support and stability can be achieved.
Abstract: The altered cast impression technique is commonly used for the mandibular distal extension partially edentulous arches. The technique is relatively simple and improves the residual ridge to dentition relationship of the prosthesis. Due to the displaceability of the mucosa, free end saddles get displaced under occlusal load. A 45-year-female patient reported to the Department Of Prosthodontics and Crown-Bridge, College of Dental Surgery, B.P. Koirala Institute of Health Sciences, Nepal with a chief complaint of missing bilateral lower posterior teeth. Clinical examination revealed missing teeth w.r.t 36, 37, 45, 46 and 47. Treatment plan was made to rehabilitate the patient with removable partial denture using functional impression along with the altered cast technique. Altered cast technique is the best alternative technique in case of distal extension cases because better tissue adaptability, proper extension of denture base, equal stress distribution, better support and stability can be achieved. Finally, increased patient comfort and function is obtained.
