“Open rest,” a new concept in the selection of the vertical dimension of occlusion

Evaluation of the utility of cephalometric parameters in constructing complete denture. Part I: placement of posterior teeth

“…For the new rehabilitation, the clinical method followed to determine the VDO and orientation of the occlusal plane used wax rims, made to average parameters and oriented parallel to the Camper plane (midpoint of the tragus – subnasal point) and the bipupillary line. They were checked from the aesthetic and phonetic standpoints (Douglas & Maritano, 1965; Javid, 1974; Palla, 1979; Spratley, 1980). The denture space was subdivided by referring to the maxillary wax rim to the upper lip, leaving 0·5–1 mm of the rim visible in the semiopen rest position; the mandibular wax rim corresponded to the equator of the tongue (Silverman, 1964; Douglas & Maritano, 1965; Pound, 1966, 1970, 1976; Robinson, 1969; Javid, 1974; Palla, 1979; Spratley, 1980).…”

“…Cephalometry has been widely used to study endentulous patients. Various types of parameters have been evaluated: position of the occlusal plane in relation to the commissure of the lips (Douglas & Maritano, 1965); reduction in the height of the face in long‐term follow up (Tallgren, 1966) or within a year of rehabilitation (Hull & Junghans, 1968; Ismail et al ., 1968) in totally or partially endentulous patients; changes in vertical dimension (Swerdlow, 1964) or in intermaxillary relationship (Tallgren et al ., 1980) immediately after prosthetic rehabilitation. Cephalometry has also been used to evaluate changes in mandibular position following muscular relaxation achieved pharmacologically (Dikshit & Mirza, 1979); and to quantify the interocclusal rest space.…”

Application of cephalometry to prosthetic dentistry – literature review

“…Cephalometry has been a diagnostic dental tool for more than 70 years. 5,6 It is possible to use cephalometric analysis to assess the orientation of the occlusal plane, [7][8][9][10][11] anterior teeth positioning, facial type analysis and the determination of vertical dimension of occlusion, anterior and posterior guidance as well as soft tissue profile. 4,[12][13][14][15][16][17][18][19][20][21][22] The starting point of each prosthetic treatment is to determine and record the three-dimensional position of the mandible in relation to the maxilla.…”

“…5,6 Metoda ta wykorzystywana jest m.in. do określania przebiegu płaszczyzny protetycznej, [7][8][9][10][11] wyznaczania pionowego wymiaru zwarcia (ang. vertical dimension of occlusion-VDO), [12][13][14][15][16][17][18] pozycjonowania zębów przednich, 19,20 wyznaczania kąta prowadzenia stawowego i siecznego, analizy kształtu twarzy oraz profilu tkanek miękkich pacjenta.…”

Reestablishing occlusal vertical dimension using a diagnostic treatment prosthesis in the edentulous patient: A clinical report

“…A review article by Turrell 8 described using preextraction records, physiologic rest position, tactile sense, facial dimensions, phonetics, swallowing, the open rest method, and esthetics to assess vertical dimension. Douglas and Maritato 14 evaluated patients at an “open rest” position and suggested that the occlusal plane should be established in terms of its relationship to the commisures of the lip, with the maxillary occlusal plane 3 mm above and the mandibular occlusal plane 2 mm below the commisures 14 …”
