The 14-item Oral Health Impact Profile (OHIP-14) is the most frequently used instrument to measure oral health-related quality-of-life (OHRQoL) in adults. Despite its popularity, its psychometric properties have been predominantly investigated based on the classical test theory while the fundamental principles of measurement have not been fully assessed. Therefore, our aim was to investigate to what extent the OHIP-14 meets the fundamental requirments of measurements.

To investigate the light penetration depth of various CAD/CAM ceramics and luting agents by spectral-domain optical coherence tomography (SD-OCT). Methods. Six CAD/CAM ceramics: lithium disilicate (LS2), zirconia-reinforced lithium silicate (ZLS), lithium aluminosilicate (LAS), polymer infiltrated (PIC), feldspar (FEL) and zirconium oxide (ZRO) and five common luting agents, two self-adhesive and three adhesive materials, were included. SD-OCT wavelengths (1310/1550 nm) and frequencies (5/28 kHz) that are particularly suitable for these materials were investigated. Subsequently, a clinical simulation was performed with an adhesively or self-adhesively inserted partial crown made of a ceramic that had an OCT penetration depth of > 1.0 mm.

The aim of this case series was to evaluate, clinically and histologically, customized-3D zirconia barriers manufactured for guided bone regeneration (GBR) procedures. Methods. Seven healthy consecutive patients with severe bone atrophy (two of them with a bilateral atrophy) were selected for a GBR procedure with a zirconia barrier. In a 3D software (DentalCad, Exocad GmbH, Germany), a virtual bone graft was designed and a shell was designed covering the graft; a standard tessellation language (.STL) file was obtained and milled (M1, Zirkonzahn, Italy) using a 1200 MPa zirconia (Prettau, Zirkonzahn, Italy). Nine GBR surgeries (8 upper-posterior jaw, 1 lower-posterior jaw) were performed using autogenous bone chips mixed with xenograft (SmartBone, IBI-SA, Switzerland / BioOss, Geistlich, Switzerland) covered with a zirconia barrier, fixed by means of screws. After healing, implant sites were prepared with a trephine bur, collecting a bone biopsy, and dental implants were inserted (Neodent, Straumann Group, Switzerland). Specimens were histologically analyzed. Results. Eight successful surgeries were recorded; one zirconia barrier got exposed after one month of healing but no signs of infection were present till the barrier was removed. In all cases it was possible to insert implants with no additional bone augmentation procedures. Histological evaluations showed the presence of intense deposition of new bone. Conclusions. Within the limitations of the present case series, the tested customized-3D zirconia barriers confirmed good clinical and histological performances, and, even in case of premature exposure, did not show signs of infection. Preliminary results suggest they are effective for GBR procedures. Further research is necessary with a larger sample size. Clinical significance. The presented barriers could be a viable alternative to titanium-reinforced polytetrafluoroethylene membranes and customized meshes.

An interim hollow shell (IHS) is a temporary prosthesis that adapts like a cap over a prepared tooth abutment. Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased.

In fixed prosthetic rehabilitations, the restorations must be designed and fabricated in a proper maxillomandibular relationship, with correct vertical dimensions of occlusion (VDO) and centric relation (CR). This short communication introduces a novel digital technique that allows to obtain the maxillomandibular record and transfer it throughout the treatment procedure. Methods: The protocol consisted of the following steps: 1. scan-jig planning and production; 2. maxillomandibular record prior to tooth preparation; 3. sequential tooth preparation and post-operative data recording through a cut-out and re-scan protocol; 4. control of the pre- and post-operative alignment of the scans in the correct VDO and CR, design and delivery of the definitive restorations. Results: There was no clinical difference in the spatial positions of the virtual models and the relationships between the arches throughout every step of the treatment. Conclusion: The main advantages of this technique are that it allows to maintain the therapeutic maxillomandibular relationship after its clinical evaluation, to reduce chair time and to avoid inaccuracies determined by multiple bite registrations.
