Crowns made from Tera Harz TC-80DP material can be used to fuse with a tooth and subsequently replace it, like, for example, bone substitutes made from hydroxyapatite, or can such crowns only be put on teeth (like mouthguards) and they do not fuse with teeth? Please explain and provide links to sources. Thank you!
Relevant answer
Answer
I am NOT doctor, it is AI suggested:
specific information or sources regarding the use of Tera Harz TC-80DP material for dental crowns or its ability to fuse with teeth. It's possible that this material may not be commonly used or well-documented in the dental field.
Typically, dental crowns are designed to fit over existing teeth or dental implants and are not intended to fuse with the natural tooth structure. They are used to restore the shape, function, and aesthetics of damaged or missing teeth. Dental crowns are usually fabricated from materials such as metal alloys, porcelain, zirconia, or composite resin.
Bone substitutes made from hydroxyapatite are used in a different context, primarily for bone grafting procedures or as a scaffold for bone regeneration in oral and maxillofacial surgery. These materials are intended to promote bone healing and integration rather than to replace teeth directly.
To obtain accurate and reliable information about specific dental materials and their applications, I would recommend consulting with a qualified dentist or prosthodontist who can provide you with the most up-to-date knowledge and guidance. They will be able to evaluate your specific case and provide appropriate treatment recommendations.
Hope it helps

Are there any problems in Dental Science especially in the field of Dental Composites and Nanocomposites or Dental materials in general that a Mechanical Engineer or Material Science researcher can solve or research upon ?
Relevant answer
Answer
As Dental practice requires a large inventory, all materials, instruments and equipments can be innovated, improved and tested using principles of Mechanical engineering and material science researchers. The discussion about new restorative material is visible in this group. However we should also think of newer materials for root canals which can match ideal requisites as well as are easy to manipulate. 3D imaging, impressions, printing, milling methods, its properties, stress distribution during function, longevity, fatigue etc can be done. There is whole world of possibilities with Finite Element Analysis.
Moreover designing new instruments with minimal likelihood of discomfort to patients and can help in best manoeuvring the oral tissues as well as materials being used in oral cavity. New designs of tongue, cheek and lip retractors which enable holding of suction tips as well as help in keeping mouth open and stabilising the head. So new retractors for use during soft tissue laser procedures. New materials which can be quickly disinfected/ sterilised? New equipments like design of dental chair lights for better visibility. Lights can be integrated in instruments/ retractors for better visibility.
The list is endless with out of box thinking for dental chairs design, operatory design, placement of operating tray near patient's mouth.
We may even design new autoclaves with specific modifications for sensitive dental instruments.
We can turn our directions into having environment friendly dental materials and consumables. The disposables used in dentistry are largely made of plastics and non recyclable materials as on now. There is a need to think about environment friendly alternates etc.

What titanium alloys are used to make dental plate and are formed at hot temperatures?
Relevant answer
Answer
.Hi Hedi,
   Commonly this material is applied for the implant of short period, the main frequent problem is the relative  sensitivity, hypersensitivity or the  biological allergy,established  increased for long time  exposure  or  direct contact with human body. in short, possible use for a short period, or by adding a biocompatible deposit or interface.

What is your opinion about chair-side pickup for mandibular or maxillary IODs. The technique in which the housings are incorporated onto the existing denture (maxillary or mandibular) and no lab steps are involved. 
Relevant answer
Answer
Chair-side intra-oral pickup is such a simple and time saving technique with good serviceability, I used it in a study to pick up O-ring attachments for four implant retained maxillary over-dentures while patients were biting in centric.

Effect of Roughness at inner wall of biomechanically prepared root canal on treatment success.
Relevant answer
Answer
Good evening. Interesting question. There are some studies showing that final irrigation protocols with extensive use of chelating substances, as EDTA and citric acid,  followed by 5% NaOCl result in destruction of collagen fibers which leads to a significant increase in the micro-roughness of the dentinal walls. But I don´t remember any research correlating microscopic observations of the dentinal walls roughness with microleakage or push-out assays.  What I do remember is that some papers showed that root canal obturation performed after EDTA + 5% NaOCl had lower apical leakage than obturation performed after a EDTA + Chlorhexidine protocol. I think that with the good quality and flowability of our newer endodontic sealers, as BC-sealer, MTA Fillapex and AH-Plus, a root canal wall with higher roughness could promote an increased contact between dentin and sealer, which could benefit the obturation. 
I hope It has helped you.

The chicken eggshell and its membranes are an inexpensive and abundant waste material which exhibit interesting characteristics for many potential applications. The eggshell is formed mainly of calcium carbonate (CaCO3) and is used widely as an animal feed, lime (Ca(OH)2) substitute or a fertilizer. Moreover, the associated eggshell membranes have a high content of bioactive components, as well as properties of moisture retention and biodegradability which have potential use for clinical, cosmetic, nutraceutical and nanotechnology applications. The eggshell membranes have been also used for biosorption of heavy metals and dyes and as a template to synthesize metal nanoparticles. The combination of nanosized calcium phosphate (Ca3(PO4)2) biomaterials synthesized from eggshell and eggshell membrane show promise to develop drug delivery system and nanowires for electronic devices. In addition, a derived product, the soluble eggshell membrane protein (SEP) has applications in tissue engineering.
Relevant answer
Answer
An interesting and logical idea. Some herbal medical experts recommend ground egg-shell as a dietary supplement for the excellent bone minerals and other proteins required for healthy cell function and bone physiology. They, do however, insist on utilising eggs produced by organic-bred chickens to avoid some of the antibiotics and synthetic supplements given to farmed/caged chickens, and to boil them first prior to use.
Chemically the mineral of human bone is a composite of (essentially) calcium phosphate whereas the main component of egg shell is calcium carbonate. There, will, of course be structural, chemical and mineral phase differences between the two, but I see no reason why egg-shell proper and it's associated proteins from membranes should not be considered for synthesising artificial tooth or bone composite materials for tissue repair/regeneration.
