Balu D. Analysis of Prevalence of Lateral Throat Form in Completely Edentulous Patients: A Systematic Review. Int J Prosthodont Restor Dent 2023; 13 (4):249-253.
Purpose: Systematic analysis of the prevalence of lateral throat forms in completely edentulous patients in different populations.
Materials and methods: Electronic databases were searched using the key terms retention and complete denture in PubMed, Embase, Scopus, Science Direct, Wiley Online Library, Cochrane Library, Lilacs, and Google Scholar from January 1990 to December 2022. A hand search of other relevant journals and references was done to find more related articles. All included studies were evaluated for the prevalence of lateral throat form type in patients wearing complete dentures.
Result: A total of 284 articles were evaluated for eligibility based on the inclusion criteria of Neil's classification of lateral throat form. Five articles were chosen for qualitative analysis. Five included studies showed the different types of lateral throat forms and various lengths of the distolingual flange in a mandibular denture. Class I lateral throat form was the most prevalent type among the completely edentulous patients, followed by class II and class III. Depth and length of the lateral throat form were maximum in class I, followed by class II and class III cases.
Conclusion: Class I lateral throat form was the most prevalent type among the completely edentulous patients, followed by classes II and III. Knowledge of the prevalence of lateral throat form in each population can help the dentist to record the distolingual area properly during the impression-making procedure.
