Objective: The objective was to determine the accuracy between functional swallowing (FS) and the Knebelman craniometric method (KCM) to measure occlusal vertical dimension (OVD) in total denture wearers.

Materials And Methods: A quasi-experimental, prospective study was conducted considering the KCM diagnostic method as the gold standard compared to FS. All the totally edentulous patients attended at the School of Dentistry of the Universidad Nacional Mayor de San Marcos ( = 32) in 2018-2019 were evaluated. Previous informed consent was obtained from all patients. A Knebelman's Craniometer was used to obtain longitudinal measurements measured in millimeters. The measurement was made with the Knebelman Craniometer by placing the tip into the external auditory canal inside the right meatus. On the other hand, for the FS method, the patients were seated comfortably with their back supported and their head in a natural position. Both upper and lower rollers were inserted into the mouth and the patient was instructed to swallow saliva for a period of 5min.

Results: When comparing the measurement of the OVD of KCM versus FS according to sex, men presented an OVD of 68.1 ± 3.9 mm, being 64.1 ± 3.8 mm in women. Accuracy was evaluated with an analysis of concordance between FS and the KCM in the determination of OVD in totally edentulous patients with a value of 0.97 (confidence interval = 0.31-0.99) ( = 0.013).

Conclusions: There is a good concordance between the FS method and the KCM at the time of determining the OVD of edentulous patients using total prostheses.

Cleaning splints (CSs) can facilitate interdental brush (IDB) insertion and guide IDBs during cleaning movement. Cleaning efficacy with and without CSs was to be assessed and compared for a fully dentate (FD) and a partially edentulous (PE) situation. For two maxillary typodont models simulating either an FD situation or a PE situation with every second tooth missing, suitable IDBs were selected and each cleaning splint was designed and fabricated by 3D-printing.

Dental implants are essential for the prosthetic rehabilitation of edentulous patients, requiring adequate bone volume and density for osseointegration and load support. The posterior region of the maxilla, commonly deficient in bone quality and quantity, represents a clinical challenge. This case series reports an analysis involving 69 dental implants in the atrophic maxilla of nine patients.

Objective: This study aimed to evaluate the clinical performance (degree of trueness) of a novel scan body "tooth-modified Scan body" (TMSB)& conventional scan body (CSB) in implant-supported full arch screw retained cases.

Methods: Seven edentulous arches (two maxillae, five mandibles) in 6 patients were rehabilitated with monolithic zirconia screw-retained implant prostheses supported by 4 (n = 1) and 5 implants (n = 6) for a total amount of 34 implants. Implant locations were scanned by intra-oral scanner (IOS) using two types of scan bodies, conventional scan bodies (CSB) in group (1) and tooth-modified scan bodies (TMSB) in group (2).

Objectives: This clinical study aimed to evaluate the accuracy of digital and conventional implant impressions in a fully edentulous maxilla and mandible.

Methods: A 53-year-old edentulous patient with four maxillary and two mandibular implants was selected. Ten intraoral scans (IOS) and a conventional impression per jaw were taken.

Article Synopsis
  • A clinical trial tested the effectiveness of adding nanogold particles to denture bases made of polymethyl methacrylate (PMMA) against standard acrylic bases, focusing on their impact on bacterial growth.
  • Twenty-two male patients with no teeth received either traditional acrylic dentures or those enhanced with nanogold, and microbial growth was measured over time around the implants.
  • Results showed that dentures with nanogold significantly reduced bacteria counts (Candida albicans, Escherichia coli, and Streptococcus mutans) at 2, 4, and 6 months compared to traditional dentures, suggesting a promising improvement in oral hygiene.
