Simultaneous repair and rebase of a removable partial denture.

A patient presented a unique dental problem: the evulsion of mandibular canines, and the restoration of anterior alveolar bone associated with periodontal disease. A mandibular removable partial denture, bilaterally supported by the canines, premolars, and molar abutments of blade implants, had been worn for more than ten years. The open clasps in the canine areas were irritating the oral tissues, and the space under the anterior saddle of the denture was retaining food. Both situations needed immediate consideration. The evulsed canines were reproduced in autocured acrylic and secured in the clasps of the denture. The space under the saddle was rebased with autocured acrylic. Since both areas were adjacent to each other, they were splinted together simultaneously. The patient was satisfied with having the old denture repaired without being deprived of the prosthesis for an extended period of time.

A metal insert to replace a fractured segment of a mandibular complete denture.

When surgical reduction is not possible for edentulous patients with little space between the retromolar pad and the maxillary tuberosity, dentures are most often made quite thin and as such are prone to fracture. When fracture of the lower denture base occurs, the denture is rebased, incorporating a case metal insert in the region of the previous fracture. Following the impression procedure, a pattern is developed on the master cast of the area to be replaced in metal. A casting is made in silver-palladium alloy and incorporated in the final wax-up. The denture is then processed by joining the metal insert into the denture.

Rebasing metal-based complete mandibular dentures.

A comprehensive rationale and technique is presented for rebasing a metal-based mandibular complete denture. It is economically practical to rebase the metal-based complete denture if it meets the criteria for rebasing. No more chair time is required for replacing a metal base than for an acrylic resin base. The only additional cost is for construction of the new metal base in the laboratory.

Functional impressions with thermoplastic materials for reline procedures.

Used as an impression material in a reline or rebase technique for a new or existing distal extension mandibular removable partial denture or mandibular complete denture, thermoplastic resin provides a denture base with uniform support under an occlusal load and a smooth nonirritating acrylic resin surface.

[Temporary and permanent tissue conditioners].

This paper reviews the different materials currently used as resilient rebasing liners in total posthodoncy, as aids for conditioning lining tissues for dentures, and describes a technique for manufacturing tissue conditioners, aimed at providing more comfort and well-being to the edentate patient.

Finite element method simulation of bone resorption beneath a complete denture.

Bone resorption beneath a maxillary complete denture was simulated by the finite element method, assuming that a threshold of compressive strain exists in the alveolar bone above which the resorption occurred. The pattern of predicted resorption was observed when 100 N of force was applied to three positions occlusally, and 20 N was applied facially. Moreover, we observed the effect of rebasing the denture after initial resorption. The results indicate that resorption was initiated on the facial and occlusal surfaces of the alveolar ridge and proceeded palatally. The resorption was greater as the occlusal load point moved facially and when the force was applied in the facial direction. When the load point was toward the facial, rebasing the denture accentuated the resorption, but when the load point was toward the palatal, the resorption was almost the same regardless of rebase. The pattern of simulated bone resorption was similar to that reported from clinical observations, which suggests that the resorption may be associated with compressive strains developed in the alveolar bone. The results argue for the importance of occlusal adjustment of dentures to move the occlusal load point palatally and produce balanced occlusion in protrusion and lateral excursions, especially after a rebase procedure.
