A method involving the digital application of the functionally generated path (FGP) technique to fabricate an implant-supported fixed prosthesis is described. It uses an intraoral optical scanner, a dental design software program, and a specially designed removable FGP table. With this method, clinicians can design custom implant-supported fixed prostheses without occlusal interferences, reducing the chairside time required to deliver the prosthesis.

Purpose: This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant-supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.
Materials And Methods: Three cylinder-shaped master files (20 mm long and 11 mm wide) with varying heights (7, 11, and 15 mm) and a titanium-base (Ti-base) abutment space were designed. These designs were used to fabricate a total of 144 specimens with two AM resins indicated for definitive use (Crowntec; AM-CT and Flexcera Smile Ultra+; AM-FS), one high-impact polymer composite (breCAM.

Purpose: This systematic review and meta- analysis aimed to evaluate the occlusion variations in single posterior implant supported fixed prostheses.
Materials And Methods: The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed and the study was registered in the international prospective register of systematic reviews (PROSPERO) platform (CRD42024501657). A systematic search of the PubMed/MEDLINE, Embase, Web of Science, and Cochrane Library databases published until December 2024 was done by 2 independent reviewers, without restriction of language or publication date.

Objectives: Precise implant placement in the anterior and posterior maxilla often presents challenges due to variable bone and soft tissue anatomy. Many clinicians elect a freehand surgical approach because conventional surgical guides may not always be easy to design, fabricate, or utilize. Guided surgery has been proven to have advantages over freehand surgical protocols and therefore, the present study proposed utilizing the nasopalatine canal (NPC) as an anatomical reference and point of fixation for a novel rotational path surgical template during computer-aided implant surgery (CAIS).

This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full-arch, implant-supported fixed dental prosthesis (FP-1). It highlights the integration of a 3D-printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling prosthetically driven implant planning and optimal bone architecture modification. The workflow incorporated fully guided implant surgery using sequential templates and immediate loading with a closed-mouth pickup system.

Purpose: To review and critically discuss current and controversial topics in full-arch rehabilitation, particularly the combination of immediate implant placement and immediate loading.
Materials And Methods: A literature review was conducted using a PubMed search of recent relevant publications regarding immediate placement and immediate loading for full-arch rehabilitation. Subtopics identified for review included the following: (1) defining a hopeless dentition and implications for full-mouth extraction; (2) the role of bone removal; and (3) the number of implants required for a full-arch fixed prosthesis.
