denture
Edentulism by definition is the state of being without teethTo establish harmony of the lower one-third of the face, the physiologic OVD must be restored and one of the prime reasons for complete denture failures is the inaccurate determination of OVDThe idea of using anthropometric measurements came from Leonardo Da Vinci drawings which have further been explored by various researchersRecording of the OVD is a tedious step in constructing complete dentures, and the limiting factor in using conventional approaches is that it depends on unreliable and inconsistent measurements of facial landmarks which vary with advancing age
