Radiographic template used to facilitate the alignment of digital scans to computed tomography scans with extensive beam hardening artifactsEndosteal dental implants have shown to be an excellent long-term resource for the treatment of edentulism.1 For decades, restorative-driven implant placement has been considered the norm for patient care,2,3 and careful presurgical planning by using accurate diagnostic elements is widely recognized as a requirement for predictable, esthetic, and functional implant placement.3
Overlay occlusion rim technique to facilitate the recording of maxillomandibular relationshipsThe efficient and accurate recording of maxillomandibular relations is an important step in prosthodontic treatment,1 with the occlusion directly affected by the accuracy of these records.2 Different methods have been proposed to perform this step, each with its advantages and limitations.3 The methods most commonly used have been gothic arch tracing and the wax recording procedure.4 Originally, these were intended for complete dentures1,3,4 but more recently have been adapted for implant-supported fixed prostheses.
A straightforward approach to conservative screw access for implant-supported fixed complete denturesFor decades, implant-supported fixed complete dentures have been used successfully to restore the masticatory system of edentulous patients.1,2 Multiple combinations of materials are available for the fabrication of these prostheses, each with different clinical indications and physical properties.3 Fixed complete dentures have a long history of use1 and have been reported to protect the bone-to-implant interface because of the shock-absorbing properties of the acrylic resin covering the framework.
Using the screw shank as a retrieval tool: A straightforward approach to removing screws with diagonal fracturesAbutment screw fracture is a mechanical complication that has been related to the failure of dental implants.1 With the advent of new prosthetic designs, new materials, and more specialized torque controlling devices, the incidence of these types of complications has decreased significantly2 and has been reported to vary from 0.16% to 3.9%.3,4 Factors such as nonaxial loading of the screw joint,5 nonpassive frameworks, presence of cantilevers, and inadequate preload of the abutment screw have been associated with screw fracture.
