Crown Impression Tips Part 3

A viewer requested some tips for final impressions. I asked a number of residents and mentors for their own tips. As well, I took a look through the literature, and textbooks (Summit (Operative Dentistry) and Schillingburg (Prosthodontics)) for other helpful tips. This will be in 3 parts.
Here is Part 1: • Crown Impression Tips

Hi. Could you be so kind as to tell me what stay on the gas means? What is that gas?

[@dr.thomasdefinnis5201]

Detailed explanation about crown impressions. Great work!

[@AllThingsDentistry]

Hi Iain, thanks for the comment. It's recommended to remove the deflective cord when taking the impression - however - every situation isn't the same and I'm sure there will be some situations (albeit rare) that you may be able to obtain a clinically accepable impression with the cord in site. However, there may be a few issues that I can think of at the moment.

[@DrAkula-rk1er]

Hi. could you explai what STAY IN THE GAS means? i cant fint an explanation of that. not a native speaker)

[@aroncarvajal7080]

Hi I have been watching some of your videos I am a dental technician and I make teeth all day the key to a beautiful functional crown is a good impression.

[@AllThingsDentistry]

Removing the cord from the impression without tearing the impression may be difficult (especially if it's a larger cord with > surface area for the material to adhere/bind to). If the impression is poured up w/ the cord, this may not be of consequence. There may be excess water in the larger deflective cord that may affect the accuracy of a fairly hydrophobic impression material (PVS). It may be difficult to effectively dry the cord, leading to increased # of bubbles in the impression.

all thanks for this experience

Hi Ashley, thanks for the info

[@capuzzo63]

Have worked in dental offices and have had my own experiences with dentists...no one ever done this procedure like this...Moreover, I am in treatment again ,because the previous dentists did not do a good procedure...it is sad, very sad!! I need to go through this pain, over and over again! I really do not understand the rush and the unconsidered work!!!!

[@whitneygivens4978]

so I'm currently trying to learn this what are the materials that u use. thanks very informative

[@Drunkinhobo]

Over all good job! Though usually you don't introduce air into the material.

[@iainhenderson7037]

Hi, was wandering do you remove only the deflective cord or keep in situ when taking the impression? Have enjoyed watching some your videos, given me some ideas, thanks again.

[@shahelahossain4425]

Hi doc, could you pls send us the preliminary impression vedio .

[@ChaN-ks3ov]

What kind of crown do I need if my root canal has been done a few years back. It’s turning grayish now. My paperwork from the dentist says Crown porcelain/ceramic substrate. Please give me input on this. Thanks in advance.

Canine guidance one sided. If the impression tray is under distortion ,it will spring back not good.

[@doctoredable]

I have to wonder how you articulate the impression.

[@KarlaFabiolaMartinezPerez]

Same question

[@chosenundead4610]

I was in a wreck last week and broke one of my front teeth in half, had to have a root canal done and I'm getting a crown but it has a rod on it to go into the canal, what do you call that?

[@doctoredable]

Flexible plastic impression trays simply distort and rebound upon removal. It is not a surprise we see so many very poor fitting crowns.

[@Hodentalcompany]

The Harmony Posterior Dual Arch Tray uses a steel distal bar. The narrow stainless steel bar at the back is only 2.6 mm in diameter, preventing tuberosity impingement, while still giving it rigidity equal or better than any other disposable Posterior dual arch tray. www.hodentalcompany.com/harmony

[@AliceBamsey]
