Purpose: To evaluate the outcome of treatment in the rehabilitation of edentulous jaws with early loaded full-arch screw-retained prostheses after up to 4 years of function.
Methods: Patients with completely edentulous maxillae and/or mandibles, or presenting natural teeth with a poor or hopeless prognosis, received 6 implants each in the mandible and/or 8 in the upper jaw. All patients received a full-arch prosthetic reconstruction.
Results: A total of 19 patients were treated with a total of 164 implants. One hundred nineteen implants were placed immediately after tooth extraction, and 45 implants were placed in healed sites. Overall, 8 implants failed, leading to a 4-year cumulative survival rate of 95.1%.
Conclusions: The rehabilitation of the edentulous maxilla and mandible with an early loaded prosthesis represents a viable alternative treatment to classic loading protocols.

Aim: The current study aimed to assess the oropharyngeal space using cone-beam computed tomography (CBCT) and its effect on airway volume both before and after denture placement.
Materials And Methods: For this investigation, a total of 15 individuals with fully edentulous upper and lower ridges, ranging in age from 40 to 70, were taken into consideration. A recording of the pulmonary function test was made both prior to and following full denture recovery.

Edentulous patients with history of cleft palate and severe maxillary atrophy are challenging patients to rehabilitate through an oral approach. The difficulty of rehabilitating these patients lies in the unusual anatomy they present and the alteration of the vascular supply of local tissues caused by the previous performed surgeries, along with other causes. This report describes the successful dental rehabilitation with zygomatic implants of a patient with complete bilateral cleft palate who was edentulous and had severe maxillary atrophy.

Statement Of Problem: Stereophotogrammetry has been proposed as an alternative to intraoral scanners for recording the location of multiple dental implants. Most studies evaluating its accuracy have been in vitro, and clinical studies are lacking.
Purpose: The purpose of this clinical study was to evaluate the precision of a stereophotogrammetry system for complete arch prostheses supported by 6 implants.

The ultimate dental implant challenge is reconstruction of the severely resorbed maxilla, especially in patients with long-term edentulism or multiple previous failed attempts at dental implant placement and full-arch implant rehabilitation. Before implant dentistry, complete dentures, which are limited by poor retention and lack of support that the alveolar ridge offers in atrophic maxillae, were the only option for these patients. Pterygoid implants are now a valid and valuable resource for the rehabilitation of the posterior atrophic maxilla.

The present article describes a step-by-step maximally digitalized workflow protocol with computer-aided design and computer-aided manufacturing (CAD/CAM) in partial-arch edentulous patients rehabilitated with fixed dental prostheses and removable partial dentures (FDPs and RPDs). Facial digitalization, intraoral scans, and functional mandibular movement recordings were used to create a 4D virtual patient on commercially available CAD software. The fixed components including post-and-cores, both metal-ceramic with extra-coronal attachment and monolithic zirconia crowns, and the RPDs were manufactured by computer numerical controlled direct milling.
