Relating Mandibular Incisor to the Lingual Frenum in Dentulous and Edentulous (Complete Denture Wearers) Subjects: An in vitro Study

Abstract

Aim and Objectives: This study is determined the vertical distance between lingual frenum and incisal edge of mandibular central incisors in dentulous subject and edentulous denture wearer subjects and their variation in different age groups and sex. Materials and Methods: This study involved 120 dentulous subjects (60 men, 60 women) and 20 complete denture wearers. Depending upon the age, the dentulous subjects were divided into three groups. Each group consisted of 40 subjects (20 men, 20 women). Group I consisted of 20-30 yr age, group II 30-4 0yr age and group III consisted of more than 40 yr age. Mandibular impressions of dentulous and denture wearers were made with irreversible hydrocolloid and cast retrieved. The vertical distance between the anterior attachment of lingual frenum and incisal edges of the mandibular central incisors for both the dentulous and edentulous subjects was measured on the casts with the help of dental surveyor. Data were tabulated and stastically analysed.

Analysis of the Distance between Lingual Frenal Attachment and Mandibular Incisal Edge Position in Establishing Occlusal Plane in Three Different Races

“…indicated that the distance between lingual frenum and incisal edges of mandibular incisors can be used as a reliable landmark when lingual frenum is recorded during function. [ 4 ]…”

“…Esthetic is very important and it is a primary concern for everyone regardless of their age. [ 1 ] Edentulous states not only compromise esthetics but also compromise the integrity of the masticatory process. [ 2 ]An edentulous state also causes loss of the occlusal plane.…”

“…Loss of teeth primarily affects the lower third of the face causing changes in facial appearance and expressions. [ 4 ] A correct occlusal plane, correct tooth arrangement, is to imitate the preextraction condition of the edentulous patient, to enhance phonetics, denture stability, and physiologic support for lips, tongue, and cheeks.
