Abstract

Background: The lateral throat form has profound infl uence on the denture success when it is meticulously utilized for retention and stability of complete dentures. Neil described 3 classes of lateral throat form with majority of edentulous patients having class I and class III being rare, but actual proportion is unknown. Aims and objectives: To investigate the proportion of Neil’s 3 classes of lateral throat form and to evaluate the difference in length of the lateral throat form between the dentures and the patients’ actual anatomy. Materials and methods: The lateral throat forms were classifi ed by the patients’ functional movements and the lengths of lateral throat form were measured by using a UNC periodontal probe intraorally as well as distolingual denture border extraorally. Results: The proportion of Neil’s class I lateral throat form was 77%, class II was 17% and class III was 6%. The mean difference between the length of lateral throat form and denture fl ange at the anterior edge of retromolar pad was 3.5 ± 1.2 mm in the right side and 3.2 ± 1.3 mm in the left side whereas at the posterior edge of retromolar pad it was 6.8 ± 1.7 mm in the right side and 6.8 ± 1.6 mm in the left side. Conclusions: The majority of lateral throat forms among the patients were class I, followed by class II and class III the least. The difference between the length of lateral throat form and denture border was statistically signifi cant (p < 0.001)
