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.

Intraoral scanning for implant-supported complete-arch fixed dental prostheses (ISCFDPs): Four clinical reports.

Although there are difficulties with using intraoral scans for implant-supported complete-arch fixed dental prostheses (ISCFDPs), several commercially available systems have become helpful in simplifying the treatment process in the prosthetic phase. These systems help patients move from interim ISCFDPs to receiving definitive prostheses in just three clinical visits. This clinical report summarizes the indications, benefits, and limitations of the four systems.

3D-printed shell complete dentures as a diagnostic aid for implant planning and fabricating interim restorations for complete arch rehabilitations: A case series.

3D-printed shell complete dentures generated from a scan of the patient's existing prostheses can simplify and expedite the surgical planning and interim restoration design for complete arch rehabilitations. Three patients were rehabilitated with endosteal implants, and interim restorations were generated from the contours of the 3D-printed shell complete dentures used as diagnostic aids. This case series report presents the recommended protocol and its clinical progression, in addition to clinical and radiographic images of the treatment outcomes.

Methods: Consecutive patients presenting indications for treatment with ZIs were treated according to ZAGA recommendations. Implants were immediately loaded.

The 3D-printed shell complete denture technique: Simplifying prosthodontic diagnosis prior to implant planning.

Traditionally, artificial teeth arrangements or the definitive complete dentures are used to establish important prosthodontic parameters such as the occlusal plane orientation, vertical dimension, and the incisal edge position. The relationship of these elements with the underlying bony structures is commonly evaluated using advanced planning protocols such as the dual scan technique. This technique article presents an uncomplicated alternative approach to establish these parameters intraorally using a 3D-printed shell complete denture generated from a 3D scan of the patient's existing complete denture.

Cross-sectional planes corresponding to the implant trajectories, designed according to a zygoma anatomy-guided approach for implants placed in the anterior and posterior maxilla, were assessed separately.

Is There a Correlation Between Airway Volume and Maximum Constriction Area Location in Different Dentofacial Deformities?

Purpose: The purpose of the present study was to correlate the airway volume and maximum constriction area (MCA) with the type of dentofacial deformity in patients who required orthognathic surgery.

Materials And Methods: The present retrospective cohort study included orthognathic surgery patients selected from the private practice of one of us. The selected cases were stratified into 5 different groups according to the clinical and cephalometric diagnosis of their dentofacial deformity.

A "Graft Less" Approach for Dental Implant Placement in Posterior Edentulous Sites.

Vertical bone augmentation techniques are more invasive than other procedures, and success rates often vary according to the surgical expertise of the clinician. As a result, there has been a trend over time towards minimally invasive treatment options in implant dentistry. This article discusses a "graft less" treatment philosophy that emphasizes the use of less-demanding augmentation techniques for the purpose of placing shorter implants in atrophic posterior sites, avoiding more complicated procedures for implant placement.

CAD-CAM cobalt-chromium surgical template for static computer-aided implant surgery: A dental technique.

A digital process for designing and manufacturing a cobalt-chromium (Co-Cr) surgical template for static computer-aided implant surgery (s-CAIS) is described. The use of Co-Cr provides the advantage of a material with improved mechanical properties to reduce the possibility of surgical template fracture during s-CAIS. The stronger material also allows for a thinner surgical template, which in turn allows better access when the interarch operative space is limited or a longer implant is inserted.

Accuracy, reproducibility, and dimensional stability of additively manufactured surgical templates.

Statement Of Problem: Additively manufactured surgical templates are commonly used for computer-guided implant placement. However, their accuracy, reproducibility, and dimensional stability have not been thoroughly investigated with the different 3D printers and materials used for their fabrication.

Purpose: The purpose of this in vitro study was to evaluate the accuracy, reproducibility, and dimensional stability of additively manufactured surgical templates fabricated by using different 3D printers.

Consideration for Contemporary Implant Surgery.

The advancement of technology often provides clinicians and patients better clinical alternatives to achieve optimal treatment outcomes. Computer-guided options allow clinicians to realize the virtual prosthodontically driven surgical plan, facilitating more predictable implant placement. Although the use of technology does not mean the clinicians can forgo the fundamental treatment principles when treating a patient, proper assessment and diagnostic approach from prosthodontic, surgical, and radiographic perspectives are still essential for a successful clinical outcome.

Computer-guided implant surgery and full-arch immediate loading with prefabricated-metal framework-provisional prosthesis created from a 3D printed model.

Objective: In this article, we describe the planning phase and clinical procedure where a CAD CAM 3D printed master model was utilized to create a prefabricated-titanium reinforced-fixed provisional prosthesis for a full-arch immediate loading after computer-guided implant placement.

Clinical Considerations: The clinical procedure should be performed based on digital planning through an advanced surgical planning software and following the guidelines of full-arch immediate loading protocol. The fact that the master model is fabricated under a computer-assisted design and computer-assisted manufacturing approach before implant placement makes the whole process considerably easier, faster, more precise and cheaper.
