Abstract: Severely resorbed residual alveolar ridges are a challenge in rehabilitation with removable complete dentures. Increased interarch space may result in increased height of maxillary and/or mandibular dentures with corresponding increase in weight, which may compromise retention and resistance of the denture and ultimately, the success of the removable prosthesis. There are many techniques and materials described for reducing the weight of dentures. This article describes an innovative technique for fabricating … Show more

Clinically, the management of severy atrophic maxilla might represent a significant challenge for the attending dentists and surgeons to successfully perform and achieve fabricated complete maxillary dentures. Making a hollow denture base for these defects has also been previously reported as a valid approach that can be used to decrease the weight of the maxillary prosthesis. Many modalities have been proposed for these procedures with favorable outcomes, and variable events of disadvantages and adverse events. This literature review aims to collect enough evidence regarding the different reported techniques of the hollow maxillary denture, according to the different studies. Many techniques have been previously reported as using magnets, using implants, intramucosal inserts, springs, suction disks, lightweight dentures, and modified impression techniques. Many materials have been previously used with the 3D spacers of the lightweight denture techniques as dental stone, silicon putty, cellophane-wrapped asbestos, light-body coated gauze, modeling clay, salt, thermocol, caramel, and glycerine soap. Favoring one of the modalities over the other requires the inauguration of future studies with an adequate sample size to validate the efficacy and safety of these modalities. All of this information is furtherly discussed within the manuscript based on the collected evidence from the different studies in the literature.

Three-dimensional printing (3DP) technology has shown great potential in rock mechanics and mining engineering due to its ability to create complex and customized objects with high precision and accuracy. At present, an emerging research focus is improving the mechanical properties of 3D-printed samples, which originally has low strength and stiffness, to match those of natural rocks. The objective of this study was to investigate the effectiveness of different post-treatments on the strength enhancement of 3D-printed gypsum samples. To achieve this goal, 3D-printed gypsum samples were subjected to different post-treatments including dipped infiltration treatment and vacuum infiltration treatment using different infiltrants: water, saltwater, ColorBond, and StrengthMax. Subsequently, each sample was subjected to ultrasonic wave velocity testing and uniaxial compression experiments to characterize their mechanical properties, CT scans to investigate their microstructural characteristics. Additionally, X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) tests were conducted to explore the underlying reasons for changes in macroscopic strength. Finally, the physical characteristics and mechanical properties of untreated and post-processed 3D-printed gypsum samples were compared with natural rocks. The results showed that the strength of samples treated with water and saltwater was much lower than that of those treated with ColorBond and StrengthMax, while the porosity was the opposite. In water-treated and saltwater-treated samples, water or saltwater treatment can alter particle characteristics, but weak adhesive bonding and numerous pores result in low mechanical strength. Samples treated with Colorbond or StrengthMax exhibit improved strength due to effective gap filling and cohesive structure formation, with StrengthMax-treated samples showing higher strength despite having more pores than Colorbond-treated ones. Moreover, the physical and mechanical properties of these treated samples matched a wider range of natural rock types compared to the untreated samples.

Removable prosthesis is probably one of the oldest types of dental therapy used to rehabilitate patients with complete or partial edentulousness. The main function of the edentulous alveolar ridge is to provide a major area of support for the dentures.1 Ill-fitting prosthesis leads to a condition where there is no longer adequate support of bone due to RRR. Hence, rehabilitation of such cases pose a clinical challenge, as there is a decreased denture foundation area for support, retention and stability.2 Residual ridge resorption (RRR) is the severe atrophy of alveolar bone underlying the mucoperiosteum. RRR affects the alveolar bone morphology, resulting in a decreased denture foundation area and increased inter-alveolar ridge space. The increase in inter-ridge distance provides a huge restorative space which results in a heavier complete denture due to greater volume of denture base material. This increase in restorative space amalgamates with the long lip length of the patient which gives rise to huge challenge to the success of the complete denture. Also, decreased denture foundation area increases the heaviness of the prosthesis and negatively affects the retention of the denture due to gravity.3 Various weight-reduction techniques have been used in the past using a rigid three-dimensional spacer, such as dental stone (Ackerman, 1955), cellophanewrapped asbestos, silicone putty during laboratory preparation to keep denture base content out of the intended hollow cavity of the prosthesis. The following case report describes a distinct lab technique for construction of hollow maxillary complete denture for a patient with severe RRR.
