    Abstract Coagulopathy is a well-recognized complication in dental surgery in patients who use oral anticoagulants or some dietary supplements. Proper pre-operative diagnosis, medical consultation, timely management, and conservative treatment can decrease the incidence of such complications. Management of bleeding during dental implant surgery commonly involves conventional methods such as discontinuation of anticoagulant use, compression, styptics, and local anesthetic administration containing vasoconstrictors. This clinical report describes the successful management of a patient with a history of coagulopathy who was rehabilitated with complete arch fixed implant-supported prostheses with immediate loading. A novel implant design with a significantly abbreviated single drill protocol for osteotomy preparation was used in an outpatient setting. The novel protocol successfully decreased the overall bleeding and significantly reduced the intraoperative time for the surgical procedure. Additional considerations related to the novel implant design and osteotomy protocol, supplementary applications, and advantages of the protocol are presented in this article.

    Abstract Complete arch fixed implant supported prosthesis made of monolithic zirconia is a popular treatment option with minimal complications, as documented in the literature over a 5-year period. One of the limitations of this material is its inability to be used when the span between adjacent implants is excessively long. A potential solution to mitigate this problem is to support the zirconia prosthesis with a metal substructure, which intrinsically has higher tensile strength. This clinical report describes the successful use of this prosthetic design in a male patient with bruxism and history of multiple implant failures in the maxilla. This resulted in a large anterior-posterior span between the anterior implants in the maxillary lateral incisor region and the distal implants in the pterygoid region. This article also describes the use of a split file digital workflow to scan the prototype prosthesis and then digitally design and mill the screw-retained cobalt chromium bar, as well as the overlaying of zirconia prosthesis which was retained by separate screws. This novel approach offers promise for management of the atrophic maxilla where implants with remote anchorage are used resulting in broader distribution of implants.

    Abstract While maxillary complete-arch fixed implant-supported prostheses are a popular treatment for patients with complete edentulism or with a terminal dentition, how speech is best optimized with this treatment is unclear. One popular method used in complete denture therapy for immediate improvement of speech, as well as to reduce the speech adaptation period for patients, is the use of a palatogram technique. Contemporary biomaterials such as zirconia used for complete-arch fixed implant-supported prosthesis are difficult to adjust and modify. Therefore, the purpose of this article was to describe the application of the palatogram technique during the evaluation stage of the maxillary screw-retained milled prototype prosthesis (interim acrylic resin prosthesis) to improve the palatal contours and optimize contact areas of the tongue with the palatal aspect of the prosthesis. The modified interim prosthesis can then be used for copy milling the definitive zirconia prosthesis. This technique is useful when other prosthodontic factors related to speech, such as the occlusal vertical dimension and tooth positions, have already been optimized.

    Abstract With the advent of computer-aided design and computer-aided manufacturing (CAD-CAM), dental restorations are no longer fabricated in an entirely analog fashion. Successful execution of complete-mouth rehabilitations requires articulation of definitive maxillary and mandibular casts with tooth preparations, as well as cross-articulation with the patient's interim restorations. These cross-articulated records serve as a guide for the dental laboratory technician in fabricating the definitive restorations. In the CAD-CAM workflow, cross-articulation and overlaying of a patient's interim casts over the definitive casts of tooth preparations poses some challenges because of loss of common anatomic data points such as incisive papilla, rugae, and the palate. This article describes a straightforward technique to overcome this common challenge, where a dental laboratory technician can predictably overlay the digitized interim casts to allow for cross-articulation and proceed with designing and fabricating the definitive restorations.

    Abstract An important step during the workflow of complete arch fixed implant-supported prostheses is the fabrication of an acrylic resin prototype prosthesis so that the patient can visualize the definitive treatment outcome or to be used as an interim prosthesis. The prototype prosthesis is typically designed digitally as a single file and is produced by milling from a solid block of white-colored prepolymerized acrylic resin. A common challenge in fabricating a resin-based prototype prosthesis is reproducing the natural appearance of the gingival architecture in gingiva-colored material. Current methods, including multicolored resin blocks, gingiva-colored stain, and layering with gingiva-colored composite resin, can be costly, time-consuming, and labor-intensive. This article describes a straightforward chairside technique that allows clinicians to fabricate an acrylic resin prototype prosthesis with appropriate gingival esthetics.

    Abstract A common challenge of fabricating a conversion prosthesis for immediate loading of dental implants is preventing the acrylic resin from flowing over the polished metal cuff of the titanium cylinders. Excess acrylic resin that accidentally flows over the polished metal cuff and adheres to it can impede insertion and the proper fit of the conversion prosthesis after surgery. Subsequent removal of the excess acrylic resin using rotary or hand instruments can scratch and damage the polished metal cuff, resulting in increased plaque accumulation and subsequent inflammation and the potential for hard and soft tissue loss during the early stages of healing. This article describes a novel device, a conversion cap, that can be screwed into the titanium cylinders to prevent any acrylic resin from flowing over the polished metal cuff. In addition, it can be attached during finishing and polishing the conversion prosthesis or definitive prosthesis to eliminate any risk of scratches over the metal cuff and allow dental laboratory technicians and clinicians to improve the quality of the prostheses.

    Abstract Recently, monolithic zirconia complete-arch fixed implant-supported prosthesis (CAFIP) has been shown to be an effective means of managing patients with edentulism or terminal dentition. Prosthetic complications have been reported to be rare, as long as there is proper treatment planning, prosthetic space and careful attention during fabrication of the prosthesis. Few reports exist in the literature that have described the management of patients with fractured zirconia CAFIP. This case report describes the successful management of a female patient with a midline fracture of a monolithic zirconia CAFIP supported by 6 dental implants in the mandibular arch. The fractured prosthesis had adequate prosthesis thickness with no distal cantilever, and opposed a similar prosthesis in the maxilla. However, upon careful analysis, diverse implant components were identified as the primary contributory factor to prosthetic misfit, and subsequent fracture. This is a new factor that requires attention by clinicians and dental laboratory technicians due to the increased prevalence of patients with preexisting dental implants. This article describes the considerations related to diverse implant components and connections from different implant manufacturers, choice of favorable implant-abutment design, technique for mitigation, and importance of passive fit for zirconia CAFIP.

    Abstract Purpose: To determine the accuracy of new electronic torque-limiting devices (ET) when compared to new and used conventional-style beam-type (BT) mechanical torque-limiting devices and hand-piece style (HS) mechanical torque-limiting devices. The secondary purpose was to compare any difference in accuracy between new and used mechanical torque-limiting devices, and any difference in accuracy when used on a straight versus an angled screw channel abutment.
    Materials and methods: A total of five torque-limiting devices were used to obtain 2000 readings under standardized conditions. An implant analog was fastened into a digital torque meter, to which an abutment was connected. Pre-determined torque values of 15 Ncm and 35 Ncm were applied, and actual torque values were recorded. A straight and an angled abutment were used to record 1000 readings each using the five torque-limiting devices. An overall Kruskal-Wallis test was applied to compare the median deviation among devices followed by a pairwise comparison ( = 0.05).
    Results: For a target torque value of 15 Ncm on a straight abutment, the electronic device (ET) was statistically more accurate than the beam type (BT) new (p < 0.001) and used (p < 0.048) devices but less accurate than the hand-piece style (HS) used device (p < 0.001). On an angled abutment for a target value of 15 Ncm, the electronic device (ET) was statistically more accurate than hand-piece style (HS) new and used devices (p < 0.001). For a target torque value of 35 Ncm on a straight abutment, the ET was statistically more accurate than the HS new device (p < 0.001) but less accurate than the BT new device (p < 0.001). On an angled abutment for a target value of 35 Ncm, the electronic device (ET) was statistically less accurate than the beam-type (BT) new device (p < 0.001), the beam-type (BT) used device (p = 0.001), and the hand-piece style (HS) used device (p < 0.001). The electronic device (ET) was the only device accurate within the ISO standard of accuracy of 6% for each of the target torque value/abutment design combinations. There was no statistically significant difference related to the type of abutment used (angled vs. straight).
    Conclusions: Electronic torque limiting devices (ET) are an acceptable method for delivering torque for implant restorations for straight and angled abutments at 15 Ncm and 35 Ncm torque values. Conventional style beam-type (BT) mechanical torque-limiting devices are a simple, predictable, validated, and inexpensive tool for delivering accurate torque at 15 Ncm and 35 Ncm torque values. The hand-piece style (HS) mechanical torque-limiting devices are predictable to deliver 15 Ncm torque values.
