“…The shrinkage causes distortions of the denture base and therefore has a negative impact on fit and retention of removable complete dentures [8][9][10]. In CAD/CAM fabrication, on the other hand, the manufacturing process is subtractive: The denture bases are milled from fully polymerised acrylic resin pucks [11] and are therefore not subject to shrinkage or distortion phenomena anymore [12,13].…”

Objectives Resin polymerisation shrinkage reduces the congruence of the denture base with denture-bearing tissues and thereby decreases the retention of conventionally fabricated dentures. CAD/CAM denture manufacturing is a subtractive process, and polymerisation shrinkage is not an issue anymore. Therefore, CAD/CAM dentures are assumed to show a higher denture base congruence than conventionally fabricated dentures. It has been the aim of this study to test this hypothesis. Materials and methods CAD/CAM dentures provided by four different manufacturers (AvaDent, Merz Dental, Whole You, Wieland/Ivoclar) were generated from ten different master casts. Ten conventional dentures (pack and press, long-term heat polymerisation) made from the same master casts served as control group. The master casts and all denture bases were scanned and matched digitally. The absolute incongruences were measured using a 2-mm mesh. Results Conventionally fabricated dentures showed a mean deviation of 0.105 mm, SD = 0.019 from the master cast. All CAD/ CAM dentures showed lower mean incongruences. From all CAD/CAM dentures, AvaDent Digital Dentures showed the highest congruence with the master cast surface with a mean deviation of 0.058 mm, SD = 0.005. Wieland Digital Dentures showed a mean deviation of 0.068 mm, SD = 0.005, Whole You Nexteeth prostheses showed a mean deviation of 0.074 mm, SD = 0.011 and Baltic Denture System prostheses showed a mean deviation of 0.086 mm, SD = 0.012. Conclusions CAD/CAM produces dentures with better fit than conventional dentures. Clinical Relevance The present study explains the clinically observed enhanced retention and lower traumatic ulcer-frequency in CAD/CAM dentures.

“…The adult human mandible is a bone which exhibits a large degree of anatomical variability (Humble, 1936;Kuznetsova et al, 1972;Tallgren, 1972;Enlow et al, 1976;von Wowern and Stoltze, 1977;Jacobsen and Krol, 1983;Poirot et al, 1986;Carter et al, 1991;Kingsmill and Boyde, 1998a). This variation occurs not only between subjects or as a result of aging, but also between the right and left sides in an individual.…”

Following tooth loss, the mandible shows an extensive loss of bone in some individuals. This may pose a significant problem in the prosthodontic restoration of function and esthetics. The many factors which have been proposed as being responsible for the inter-individual variation in post-extraction remodeling mean that a perfunctory analysis of the literature, in which well-controlled, relevant studies are scarce, may not provide the whole story. This article reviews the local and systemic factors which may play a role in the post-extraction remodeling of the mandible. Since severe residual ridge resorption may occur even when the bone status in the rest of the skeleton is good and vice versa, it is concluded that local functional factors are of paramount significance. It is now essential to determine how they can be modified and applied to help maintain ridge height and quality in our aging, edentulous population.

“…El RM se deforma bajo presión, por lo que la impresión debe registrarlo de manera estática y transmitir la carga oclusal a la mayor zona de soporte posible (5) . En este caso la mucosa se presenta sana, por lo que no es necesario el uso de acondicionador de tejido previo a la impresión preliminar.…”
