The following technique describes the virtual planning of a single implant by combining an intraoral digital scan, an open-source computer-aided design software program, bone sounding, and 2D radiographic imaging. The surgical implant guide is fabricated using additive manufacturing technologies. Further, the surgical implant guide positioned in the patient's mouth is used to radiographically verify the estimated mesiodistal implant angulation before proceeding with the surgical intervention and can be modified if necessary.

A strong body of scientific evidence indicates that a four dental implant-supported prosthesis is well suited for a full-arch rehabilitation. Yet, countless edentulous patients who could benefit from this established concept are left untreated because of high costs. This article describes a novel workflow that enables the fabrication of a metal-resin fixed hybrid prosthesis supported on four implants, with a variable cost for parts and material of around $400 and a (laboratory) production time of approximately 4 hours.

Materials And Methods: Three systematic reviews and one narrative review were written to address focused questions on (1) the indications for the use of zygomatic implants; (2) the survival rates and complications associated with surgery in zygomatic implant placement; (3) long-term survival rates of zygomatic implants and (4) the biomechanical principles involved when zygoma implants are placed under functional loads. Based on the reviews, three working groups then developed Consensus Statements and Clinical Recommendations.
Digital dental technology has revolutionized the workflows in the dental laboratory and clinical environment. Although the novelty of digital dentistry can be alluring, clinicians should bear in mind that the overall outcome is what matters most rather than the path taken to achieve that outcome. Combining analog and digital pathways can serve to amplify each one and thus enhance the result.

A 3D printed registration device is described for implant-supported complete dentures that simultaneously register implant position, soft-tissue contour, anterior tooth position, occlusal vertical dimension, and centric relation. This information is captured clinically in 10 to 20 minutes and can then be transferred to the dental laboratory technician to continue the prosthetic workflow. The standard tessellation language (STL) file for the registration device is available for free download and use.

A novel technique is described combining a modified digital complete denture workflow with analog components and systems, allowing the use of multicolored zirconia and 3D-printed resin. In combination with an appropriate metal substructure, a high-quality prosthesis can be fabricated with reduced effort and cost.
View Article and Find Full Text PDFA substructure is required for an implant-supported fixed complete denture that is sufficiently strong and supportive to function reliably. A novel prefabricated modular system that allows for the analog generation of a passively fitting, supportive, titanium framework for a 4-implant fixed complete denture is described. The process allows the delivery of an immediate, definitive prosthesis on the same or the next day.

The metal-resin hybrid full-arch prosthesis has been a traditionally used type of restoration for full-arch implant fixed dentures. A newer development has centered around the use of monolithic zirconia or zirconia veneered with porcelain. Being a ceramic, zirconia has the potential for fracture.

Anatomically contoured healing abutments have been shown to contain and protect slow-resorbing substitution grafts, resulting in bone and soft-tissue volume augmentation. Even in healed sites customized healing abutments have demonstrated favorable outcomes compared to standard healing abutments. Through two separate cases, this article describes a technique that enables simple chairside fabrication of precisely contoured customized healing abutments and exact 3-dimensional intraoral positioning.

Duplicating this information in an expedient, precise, and sanitary fashion is desirable so that the interim restoration can be returned to the waiting patient. A technique is described to fabricate an accurate definitive polyvinyl siloxane cast with laboratory analogs bonded to a prepolymerized, dimensionally stable, composite resin baseplate.

A technique is described to generate a framework for an implant-supported fixed complete denture. The main advantage of the described technique is the low production cost of a framework that has high strength, passive fit, and distinct retentive structures for each denture tooth.
View Article and Find Full Text PDFA technique is described which will generate a customized healing abutment for a dental implant to allow the development of ideal soft tissue contours. With implant position and soft tissue contours defined at surgery, customized impression techniques can be used to capture those details and help generate the definitive implant-supported restoration. This workflow reduces the number of patient visits.

The hard resin prevents seating beyond the height of contour, hence these guides are not intrinsically retentive. By covering the guide with a flexible thermoplastic material that extends into the undercuts, the resulting guide now has a retentive feature.

This in-office system consists of prefabricated parts that are assembled onto a carrier. The 3-dimensional data are derived from a dental cast in combination with a periapical radiograph or cone-beam computed tomography data.

Purpose: This is a pilot study evaluating the effect of the algorithms and production processes of four commercial manufacturers of stereolithographically produced surgical guide.
Materials And Methods: A singular Dicom file was used to produce six distinct duplicate dentures, which function as the base for surgical guides. The duplicate dentures were repeatedly fitted (n = 10) into an impression of the occlusal surface of the original scan appliance.

Background: Template-based computer-guided implant placement holds the promise of more precise and less traumatic placement of dental implants. Errors in the fabrication process of the surgical guide may lead to unfavorable clinical outcomes.
Purpose: This report discusses the potential of unintentional volumetric deformation of stereolithographically (SLA) produced surgical guides (NobelGuide, Nobel Biocare AB, Göteborg, Sweden) compared with the original scan denture.
One of the most challenging aspects of implant placement is the correct spatial positioning of the dental implant in the bone. Surgical guides of various configurations have been proposed to aid implant placement. If a fully limiting surgical guide is used, the encoded information should be reliable, as deviations are not possible during surgery.
