objectives: to compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. patients and methods: in a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary ...

PURPOSE To describe the use of a computer-aided three-dimensional planning protocol in combination with previously placed reference elements and computer-aided design/computer-assisted manufacture (CAD/CAM) technology to restore the partially edentulous patient. MATERIALS AND METHODS Mini-implants and/or reference brackets were inserted or positioned in specified locations in a test cast and ...

BACKGROUND Immediate-function Brånemark System implants (Nobel Biocare AB, Gothenburg, Sweden) have become an accepted alternative for fixed restorations in edentulous mandibles, based on documented high success rates. Continuous development is ongoing to find simple protocols for their use. PURPOSE The purpose of this study was to develop and document a simple, safe, and effective surgical a...

Anatomic factors include decreased bone quantity, especially in older edentulous or partially edentulous patients who have experienced alveolar resorption in the wake of tooth loss. The antrum also tends to enlarge with age, as well as with edentulism, and this further decreases the amount of available bone. In addition to the diminished quantity, bone in the posterior maxilla often is softer a...

Treatment options for insufficient ridge morphology includes the use of short implants, vertical ridge augmentation procedures, or cantilever prostheses in completely edentulous patients. Due to the less predictable long-term prognosis associated with the above-mentioned procedures, the “All on 4” technique was proposed for the rehabilitation in edentulous jaws. The All on 4 treatment concept m...
