Quick guide to design a Screw-Retained Implant Crown.
Screw-retained or cement-retained?
Which one to choose when making clinical decision?
Both fixed dental restorations have pros and cons. Which one to choose depends on some factors such as retention, retrievability and esthetics.
Cementation is the most commonly used restoration in dental implantology. Advantages include the compensation of improperly inclined implants, easier achievement of passive fit due to the cement layer between the abutment and reconstruction, lack of a screw access hole, and thus the presence of an intact occlusal table and easier control of occlusion. The major disadvantage is the difficulty of removing excess cement, which has been associated with the development of peri-implant mucositis and peri-implantitis.
Screw-retained restorations on the other hand have the advantage of more predictable retrievability. They require a minimal amount of interocclusal space and are easier to remove when hygiene maintenance, repairs or surgical interventions are required. Additionally, angulated screw channel solutions have made screw-retained restorations available for a wide range of indications.

I think in ExoCad 3.0 (Allow any changes) in no more available. it doesn't let you cut all the crown. is there any fix?

[@Best_clipz_z]

On mine it says adapt instead of ATT

[@iavorpuhlev2283]

Hello, Is it nessesary Implant module to achieve this result. I tried but the basic software doesn`t cut the whole crown to have a hole.

[@wixur]

Hi Iavor, Yes, you need to choose it's type from "profiles" window as mentioned in the video.

i have to do this when choosing a customised abatment?(and it doesnt cut it all the way throught)/ if i choose scrwed crown it comes cut right?

[@wixur]

There are new features available with latest version of exocad. Try it😉

[@ericadonaire631]

what if we do not have the allow changes option?

[@wixur]

Hello Etica, Which options do you mean?

[@JayLittlefield]

I do this exactly, but it leaves a thin layer on the occlusal still- like a "minimal thickness" requirement for the crown itself and does not cut all the way through. Any suggestions?

[@wixur]

Hi Jay, It may be because of "screw channel protection". Can you send us a screenshot to [e-mail]? I will check it 🙂

[@JayLittlefield]

@@wixur I will do it right now

Hi again, Thanks for the email. What you need to do is checking "allow any changes" in attachments tab. Note that this checkbox is only available if you have "implant module" activated on your dongle. Keep in touch!
