BACKGROUND Currently, there are no suitable assays available to evaluate the embryotoxicity of leached components from restorative dental materials. METHODS The effect of the medium conditioned by composites and amalgam on mouse blastocysts in vitro was tested. The materials were also subcutaneously implanted, and the effect of the medium supplemented with serum from the host blood was evalua...

The success of dental implantation is connected with the so-called implant primary stability, a synonym for the implant anchoring inside the bone. The primary stability is related to the applied peak torque to the implant during the insertion process. This work simulates the process of insertion of a typical commercial implant into the jaw bone (mandible) using a 3D dynamic non-linear finite-el...

Dental implantation is popular treatment for edentulous and partially dentate patients. Effectively assessing interfacial bone defects and osseointegration requires considerable effort for successful implantation. This study presents the development of a noncontact detection technique that uses a loudspeaker and a noncontact cylindrical capacitive-type displacement sensor to measure and evaluat...

Maxillary sinus membrane (MSM) elevation is a common surgical technique for increasing bone height in the posterior maxilla prior to dental implant placement. However, the biological nature of bone regeneration in MSM remains largely unidentified. In this study, MSM tissue was obtained from 16 individuals during orthognathic surgery and used to isolate MSM stem cells (MSMSCs) by single-colony s...

Methods to improve osseointegration that include implantation of rhBMP-2 with various kinds of carriers are currently of considerable interest. The present study was conducted to evaluate if the rhBMP-2 loaded β-TCP microsphere-hyaluronic acid-based powder-like hydrogel composite (powder gel) can act as an effective rhBMP-2 carrier for implantation in host bone with a bone defect or poor bone q...

Image-guided otologic surgeries performed on healthy patients require non-invasive fiducial systems that achieve submillimetric target registration error (TRE). We have described such a system that attaches repeatably to a subject via a dental bite block [1]. We now describe a new method for the clinical validation of such a system that can be conducted in the laboratory with no intraoperative ...

BACKGROUND/AIM There is a controversial opinion among implantologists on the method of dental implantation that provides more favourable response of soft and bone tissues. The aim of this study was to pathohistologicaly compare the influences of one- and two-phase implant surgical methods on the periimplant epithelial tissues. METHODS The experiment was performed on 10 dogs. Eight weeks follo...

Dental implants constitute a well-established approach for replacement of lost teeth with titanium being the most favored material for implantation. However, titanium has its limitations in esthetically demanding cases and neither the form nor material of such implants has changed much over the past 40 years. Today, there is scientific evidence that zirconia dental implants osseointegrate well ...

Two groups of titanium dental implants, identical in geometry but different in the treatment of their surfaces, were tested in an in vivo minipig model of the mandible. The surfaces that were tested were, first, sandblasted and acid-etched; and secondly, sandblasted, acid-etched, and conditioned. The removal torque was assessed at 2, 4, and 8 weeks after implantation (n=6 animals in each healin...

The importance of soft tissues for the maintenance peri-implant tissue health is one most discussed topics in dental implantology. Numerous studies confirm that presence affects aesthetic result and long-term survival implants. It was suggested surgical procedures aimed to increase mucosa improve outcomes implant treatment. This literature review aims make an overview methods management around ...
