Weighted mandibular complete denture fabricated by using selective laser melting: A clinical report
The rehabilitation of patients with severely resorbed mandibular ridges can be a clinical challenge when rehabilitation with endosteal implants is not the elected treatment. Historically, weighted mandibular complete dentures have been used successfully to manage patients with severely resorbed ridges, and the weight of their cast metal has been calculated by using the weight of the wax and the density of the alloy. This clinical report presents the management of an 87-year-old woman with a severely resorbed mandibular ridge by using a weighted mandibular complete denture fabricated by using selective laser melting (SLM) technology in which the weight of the metal base was calculated by using the volume of the digital file used for manufacture.The use of selective laser melting in the fabrication of maxillary and mandibular metal base complete dentures for a patient with Ehlers-Danlos syndrome: A clinical report
Ehlers-Danlos syndrome is a rare hereditary disorder of the connective tissue that can have oral manifestations that can complicate the prosthodontic rehabilitation of edentulous patients. Intraoral features such as fragile mucosa, impaired healing, limited intraoral space, and a deep palatal vault can compromise treatment with conventional complete dentures. This clinical report describes the management of a 30-year-old edentulous man with Ehlers-Danlos syndrome by using metal base complete dentures fabricated with selective laser melting (SLM) technology.Fabricating a screw-retained, complete arch, fixed implant prosthesis using selective metal laser sintering: A clinical report
In contemporary prosthodontic practice, implant-supported therapy has consistently resulted in high success rates, with satisfactory and predictable outcomes for completely edentulous patients. Of the several options, complete-arch, fixed screw-retained solutions are generally considered to be the preferred treatment solution. Screw retention offers advantages such as predictable retrievability and potentially easy prosthodontic maintenance, as well as excess cement not being a concern. However, implant mispositioning and malalignment may often necessitate the use of cement-retained prostheses.Titanium implant wear from a zirconia custom abutment: A clinical report
This clinical report describes damage to a 1-piece zirconia abutment where both biological and mechanical complications developed, resulting in premature loss of the implant. Scanning electron microscopy showed significant damage to the internal connection of the implant. When using 1-piece zirconia abutments with a titanium internal connection, periodic recall and identification of wear is necessary, especially in patients with repeated screw loosening.Modification of clinically short Locator abutments using laser welding
As dental implants continue to survive longer, managing and maintaining implant prostheses can be complicated by the lack of compatible parts or the discontinuation of implant systems. This report describes a laser welding procedure for the management of clinically short Locator abutments (Zest Anchors Inc) that lacked a commercially available, compatible alternative.
