BACKGROUND: Palatomaxillary defects were historically restored with a prosthetic obturator; however, advances in local and free tissue transfer has provided a viable alternative for appropriately selected patients with palatomaxillary defects. METHODS: A retrospective chart review of patients who underwent palatomaxillary reconstruction by the lead author between 1998 and 2016 was conducted. Patients who were restored with a palatal obturator were excluded. RESULTS: One hundred forty patients were reconstructed with a total of 159 local, regional, and free flaps with a 96...

In the full-mouth rehabilitation of a patient with severely collapsed occlusion, a multidisciplinary approach including prosthodontics, orthodontics, endodontics, and surgery could provide better esthetic and functional results. Orthodontic treatment aiming for stable occlusion that meets the standard requirement of functional occlusion, enables the maintenance of occlusal function, and guarantees long-term stability on the basis of periodontal health was attempted. The essential element of this protocol is careful treatment planning based on the optimal sequence pursuing functional occlusion...

This case history report describes the long-term prosthodontic treatment of a patient with gnathodiaphyseal dysplasia (GDD). The patient was initially diagnosed with osteomyelitis in the maxilla in 1986, followed by osteonecrosis spread throughout the mandible. GDD was genetically diagnosed in 2006. Despite the severe alveolar bone resorption, prosthodontic treatment improved the patient's satisfaction and ability to perform essential functions. Regular prosthesis adjustments and periodic follow-up should continue to avoid future complications...

There is a recent trend in tissue engineering and regenerative medicine to use nanotechnology and bionanomaterials to obtain materials that mimic the surface properties of a natural tissue. From this perspective, nanolevel tissue engineering can be viewed as a novel anatomy of the future. In this paper, a novel titanium-based alloy is studied following this strategy. The alloy nanostructuration is proposed as an improved alternative for restorative prosthodontics or an implantable biomaterial. Tests in i) standard solution of simulated body fluid (SBF) and ii) natural saliva were performed to investigate the alloy's electrochemical stability...

PURPOSE: In the field of prosthodontics, patients often require complex and extensive restorative care. This can involve the use of dental restorations to restore teeth on both the maxillary and mandibular arch. Current literature has evaluated the wear properties of different dental ceramics against enamel, but studies regarding dental ceramics opposing one another are limited. The purpose of this study was to assess the wear potential and wear behavior of CAD/CAM zirconia (ZR) and lithium disilicate (LD) materials against a similar ceramic material, and how the surface finish of these dental ceramics might affect patterns of wear...

Periodontal plastic surgery comprises an increasing part of clinical periodontology. Clinical trials have traditionally used professionals to judge esthetic outcome, and few studies have addressed patient needs and requests (true end points). Development of universally accepted and validated methods for professional esthetic assessment, together with standardized questionnaires for patient-perceived outcome, may help to provide better insights into the true needs and benefits of periodontal and implant-associated plastic surgery...

The ability of dental students to interpret digital panoramic radiographs (PANs) of edentulous patients has not been documented. The aim of this retrospective study was to compare the ability of second-year (D2) dental students with that of third- and fourth-year (D3-D4) dental students to interpret and identify positional errors in digital PANs obtained from patients with complete edentulism. A total of 169 digital PANs from edentulous patients were assessed by D2 (n=84) and D3-D4 (n=85) dental students at one Canadian dental school...

The analysis of dental students' clinical production/participation has been used to assess whether a prospective graduate is capable of unsupervised and independent practice (that is, competent to perform that practice). This method and others have inherent biases that may not accurately reflect whether the student has mastered the associated concepts and techniques required for dentistry. The aim of this study was to assess an informatics system that assigned curriculum meta-tags with time-based relative educational value units (ReVUs) to each clinical procedure performed by Medical University of South Carolina (MUSC) students...

Edentulism presents an ongoing challenge for prosthodontic dentistry. Many aspects of complete denture construction lack contemporary evidence. One such aspect is denture occlusion. Balanced occlusion (BO) has become the prevailing occlusal scheme. It has been suggested that canine guidance (CG) is unsuitable for complete denture occlusion due to an increased risk for tipping of the prostheses. However it may be indicated in patients with minimal alveolus resorption. There has been limited evidence suggesting the superiority of either occlusal scheme over another...
