Stable cranial parameters to evaluate the occlusal plane orientation in the frontal plane: a systematic review.

Introduction: A systematic review of the literature available up to October 2020 has been conducted to determine which cranial plane could represent a stable and reliable parameter to evaluate the orientation of the occlusal plane in a frontal view.

Evidence Acquisition: An electronic research was performed across the following electronic databases: PUBMED, EBSCO, SCOPUS, WoS, COCHRANE LIBRARY, SciELO, EMBASE and GOOGLE SCHOLAR. Observational studies based on imaging and anthropometry were identified, and all languages have been included.

Eagle and Ernest syndromes: a scoping review.

Introduction: Ossification disorders can affect the stylohyoid ligament as well the stylomandibular ligament. The symptomathology between those syndromes and other pathologies it has been a problem because there is not a guideline.

Evidence Acquisition: With the aim to establish prevalence, diagnosis and etiopathogenesis of Eagle and Ernest syndromes, a scoping review was performed base on PRISMA criteria.

Flapless Cone Beam Computed Tomography-Guided Implant Surgery with Contextual Transcrestal Sinus Lift Augmentation Using New Bone Compactor Tools.

In the present paper, the authors present a case report of premolar edentulism in the upper jaw treated through a guided flapless oral implant surgery with contextual crestal sinus lift, performed with a system of manual screw-tapered bone expanders (B&B Dental, San Benedetto, BO, Italy). The surgery was planned by means of dedicated software, through which the data obtained from the CBCT and from intraoral scanner impression were matched, with consequent production of a surgical template. The proposed surgical procedure is minimally invasive, very simple, and fast and ensures good comfort for the patient by avoiding the elevation of mucoperiosteal flaps and uncomfortable malleting maneuvers.

A New Bioactive Glass/Collagen Hybrid Composite for Applications in Dentistry.

Bioactive glasses (BGs) are currently employed in a wide range of medical and dentistry applications by virtue of their bone-bonding ability. The incorporation of BGs into a collagen matrix may be used to combine the regenerative potential of these materials with the specific biological advantages of collagen. However, most of the collagen/BG composites reported in the literature are scaffolds and there is a lack of moldable putties or injectable systems.

Long-term survival analysis of standard-length and short implants with multifunctional abutments.

Background: Spherical shape and connecting bypass screw of the OT Equator abutment (Rhein83, Italy) provides several retentive possibilities, even in non-parallel implants.

Objective: This study assessed the long-term survival of standard-length and short implants receiving this multifunctional abutment.

Methods: Partially, edentulous patients (44 males and 64 females) (mean age 58.

Surface treatments to improve the repair of acrylic and bis-acryl provisional materials.

Purpose: To evaluate the in vitro effects of the Composite Primer and different surface treatments on the shear bond strength (SBS) of acrylic and bis-acryl repairs with resin composite (RC).

Methods: Acrylic (Alike) and bis-acryl (Protemp 4) blocks were prepared. Surface roughness was standardized (0.

Long-term Short Implants Performance: Systematic Review and Meta-Analysis of the Essential Assessment Parameters.

Lack of standard criteria in the outcome assessment makes it difficult to draw conclusions on the clinical performance of short implants and, under these circumstances, determine the reasons for implant failure. This study evaluated, through a systematic review of the literature and meta-analysis, the essential parameters required to assess the long-term clinical performance of short and extra-short implants. Electronic databases (Pubmed-MEDLINE, Cochrane Library Database, Embase, and Lilacs) were searched by two independent reviewers, without language limitation, to identify eligible papers.

Implant-retained removable partial dentures: an 8-year retrospective study.

Purpose: To evaluate the long-term outcomes of removable partial dentures (RPDs) retained (but not supported) by dental implants.

Materials And Methods: We retrospectively evaluated 32 consecutive patients who received implant-retained RPDs. Each patient received one to four endosseus implants; the sample included a total of 64 implants.

Dimensional tolerances and assembly accuracy of dental implants and machined versus cast-on abutments.

Background: The clinical application of prosthetic components obtained by different manufacturing processes lacks technological foundation: the dimensional tolerance of individual parts and their assembly accuracy are not known. The rotational misfit (RM) of the hexagonal connection is critical in single-tooth implant restorations, but no standard control procedures are available for its evaluation.

Purpose: The research aimed at proposing a new protocol for the dimensional assessment of implant-abutment connections, based on noncontact measurement and statistical data processing.

A new generation of sterile and radiopaque impression materials: an in vitro cytotoxicity study.

Impression materials are largely used to record the geometry of dental tissue. Hence, the assessment of their possible cytotoxicity is a necessary step in the evaluation of their biocompatibility. The present study is carried out to evaluate the cytotoxicity of a new elastomeric sterile and radiopaque impression material.

Study of the potential cytotoxicity of dental impression materials.

The aim of this study was to assess the cytotoxicity of tow types of impression dental materials: polyethers (Impregum Penta, Permadyne Penta Heavy and Light) and vinyl polysiloxanes (Elite Mono Tray, Medium, Low viscosity and Elite H-D Putty). Their cytotoxic effects were studied by indirect and direct tests. The indirect tests were performed by incubating impression materials in serum free cell culture medium to prepare the soluble extracts.
