Anterior tooth positions in prosthodontics

Abstract

The problems associated with positioning anterior health teeth in prosthetic treatment procedures are discussed and some recent work reviewed. Useful guides for establishing the artificial anterior dental relationship have been described and an application of these guides has been illustrated.

The Position of the Occlusal Plane in Natural and Artificial Dentitions as Related to Other Craniofacial Planes

“…The use of a number of anatomical landmarks as guides from life or biometric guides for artificial tooth position has been suggested by many authors 8–11 . Anatomical landmarks suggested to clinically determine the position of the occlusal plane are the upper lip, corner of the mouth, 11 lateral margins of the tongue, two‐thirds of the height of the retromolar pad, parallel to the ala‐tragus (Camper's plane) and interpupillary lines, 6,7 parallel to the hamular notch‐incisive papilla plane, and 3.3 mm below the parotid papilla 12,13 …”

Some advances in endosseous implants

“…Furthermore, other methods of reducing occlusal stress on an implant have yet to be investigated, e.g. regulation of bite force (Hannam, 1976), type and location of occlusal superstructure (Murray, 1977). Such factors may well influence the prognosis of endosseous dental implants.…”

Intercondylar width as a guide to setting up complete denture teeth

“…Harper (1948) stated that the incisal edges of the upper central incisors should be set 5–8 mm in front of the centre of the papilla. Hickey, Boucher & Woelfel (1962), Martone (1963), Murray (1977) and Mavroskoufis & Ritchie (1981) preferred 8–10 mm for this measurement, whereas Schiffman (1964) related the canines to a line bisecting the papilla. Erlich & Gazit (1975) found that the labial surfaces of the central incisors were an average of 12–13 mm anterior to the midpoint of the papilla.…”
