Effect of Cantilever Extension on Bone Loss in Mandibular Complete-Arch Implant-Supported Fixed Prostheses with Three and Four Implants.

Purpose: To compare the peri-implant bone loss of mandibular complete-arch implant-supported fixed prostheses (FPSs) supported by three and four implants and to correlate with the size of the horizontal and vertical distal cantilever at prosthesis placement (T1) and after 1 year (T2).

Materials And Methods: A total of 72 external hexagon (EH) type implants were placed in 20 participants. Of these, 24 supported an FPS with three implants (G3I) and 48 with four implants (G4I).

Conventional and digital maxillary occlusal record for the manufacture of complete-arch implant-supported fixed prostheses: randomized controlled clinical trial.

Objectives: To evaluate the trueness of the digital maxillary occlusal records in comparison with the conventional records for the fabrication of complete-arch implant-supported fixed prostheses.

Materials And Methods: This randomized controlled clinical trial followed the recommendations of the CONSORT statement. Twenty participants who used a mandibular interim complete-arch fixed prosthesis and conventional complete maxillary dentures were included in the study.

Accuracy and reproducibility of real and virtual occlusal contact points in implant-supported fixed prostheses.

Aim: To evaluate the accuracy and reproducibility of real and virtual occlusal contact points in implant-supported, fixed complete dentures.

Materials And Methods: The study included 19 participants using mandibular interim complete-arch fixed prosthesis supported by 3 or 4 implants as opposed to conventional removable complete dentures. At installation, an examiner installed the prostheses and verified the occlusal contact points through 2 methods: recording the real contact points with carbon paper (RC) followed by occlusal photography and intraoral scanning (VC) to record the virtual contact points to obtain a screen print of the software.

Device trueness in passivity and misfit of CAD-CAM frameworks: Conventional versus printed casts.

Statement Of Problem: Obtaining a passive and well-adapted framework is challenging when intraoral scanning edentulous arches with multiple implants. The trueness of the printed casts is unclear.

Purpose: The purpose of this clinical study was to evaluate the trueness of frameworks made from conventional and printed casts regarding clinical passivity and misfit.

Effect of cantilever extension on bone loss in mandibular complete-arch implant-supported fixed prosthesis about 3 and 4 implants.

Statement Of Problem: The assessment of bone loss around implants has been widely studied, but the effect of cantilever length as a risk factor is not fully understood.

Purpose: The objective of this randomized controlled clinical trial was to compare the peri-implant bone loss of mandibular complete-arch implant-supported fixed prosthesis supported (FPS) by 3 and 4 implants and to correlate with the size of the horizontal and vertical distal cantilever at prosthesis installation (T1) and after one year (T2).

Materials And Methods: 72 external hexagon (EH) type implants were installed in 20 participants.

Conventional and digital impressions for complete-arch implant-supported fixed prostheses: time, implant quantity effect and patient satisfaction.

Purpose: To evaluate and compare the effect of impression type (conventional vs digital) and the number of implants on the time from the impressions to the generation of working casts of mandibular implant-supported fixed complete-arch frameworks, as well as on patient satisfaction.

Materials And Methods: 17 participants, 3 or 4 implants, received 2 types of digital impression methods (DI) and conventional (CI). In DI, two techniques were performed: scanning with the scan bodies (SC) and scanning with a device attached to the scan bodies (SD) (BR 10 2019 026265 6).

Partially digital workflow for making complete-arch implant-supported fixed prostheses: A dental technique.

This article describes a technique for making complete-arch implant-supported fixed prostheses by using intraoral scanning and computer-aided design and computer-aided manufacturing (CAD-CAM) technology for the fabrication of a metal substructure and conventional processing for the prosthesis base. For this, a device was designed to accurately capture the position of multiple implants and the associated digitalized surgical guide, and the metal substructure was planned and milled directly in cobalt-chromium. The color of the gingiva and artificial teeth was selected by using the intraoral scanner software program, and the prosthesis base was processed conventionally.

Trueness of a device for intraoral scanning to capture the angle and distance between implants in edentulous mandibular arches.

Statement Of Problem: The digitalization of completely edentulous arches presents limitations because of the lack of anatomic structures for best-fit alignment during the image generation process of the scanner's software program.

Purpose: The purpose of this clinical study was to evaluate a new device for intraoral scanning and to analyze its usefulness in capturing the 3-dimensional (3D) position of implants in edentulous mandibular arches.

Material And Methods: The 3D positions of 40 implants in 10 participants with fixed interim mandibular prostheses were evaluated by comparing 3 scanning techniques.

Manual Therapy in the Treatment of Myofascial Pain Related to Temporomandibular Disorders: A Systematic Review.

Aims: To evaluate the effectiveness of manual therapy in the treatment of myofascial pain related to temporomandibular disorders.

Methods: Randomized clinical trials were searched in the Cochrane Library, MEDLINE, Web of Science, Scopus, LILACS, and SciELO databases using the following keywords: temporomandibular joint disorders; craniomandibular disorders; myofascial pain syndromes; myofascial pain; exercise therapy; myofunctional therapy; physical therapy modalities; clinical trial; prospective studies; and longitudinal studies. Studies using the RDC/TMD and manual therapy for myofascial pain were included.

Improvement in Quality of Life of Elderly Edentulous Patients with New Complete Dentures: A Systematic Review.

Purpose: To evaluate whether treatment with new complete dentures improves quality of life in elderly patients.

Materials And Methods: A literature search was conducted in the MEDLINE/PubMed, Scopus, LILACS, SciELO, Web of Science, and Cochrane Library databases using specific keywords for relevant articles published up to March 2018. Three reviewers obtained the data and compared the results from reports that evaluated denture wearers 60 years of age or older whose old dentures were replaced with new ones.
