Anon. asks:
I have a patient who is treatment planned for a maxillary overdenture supported by 4-implants in the second premolar and canine areas. I usually have my lab make a custom tray for an open tray impression. I am in serious financial decline in my practice due to the economy. Could I take the index impression with a stock plastic tray? I am just trying to save the lab cost on the custom tray.

  I sometimes make my trays myself, usually when I need to complete treatment in short time. Depending on the resilience of soft tissues sometimes standart trays may be succesfull, but in case of an overdenture on 4 implants,the quality of your impression will determine the longevity and success of your treatment. In your case, I’d recommend you to make your own tray rather then using a standart one.

  I agree with Dr AYP, the overdenture will be much more precise and probably you will not have as much corrections to make as if you take the impression with a standard tray.
  But for implant supported overdentures individual tray is not imperative. I`ve had more than 20 cases taken with standard plastic tray, and another 50 with individual ones. No singnificant difference between them. Just make sure implant transfers are solid locked with pattern resin, implants aremore-less parallel (so thy don`t move in your tray and induce deformations).
  Best of luck:

  I perform full mouth rehab on a most regular basis. Usually a stock plastic tray is just fine. However, when you have numerous teeth involved, I get better fitting of the casting, using a stock metal tray.

  Poour Mr. Anon,
  I suppose when you calculate the price of an individual tray and your impression material, these will be (in percentage) peanuts compared to the price of the implants plus the overdenture. If it is really so expensive I can advice you Hager & Werken in Duisburg, Germany. They will introduce a standard imp. tray with a membran ath the cristae area. Easy to use and disposable. By the way, what is the cost of an individual impresion tray in the US?

  Kind regrds from Belgium,
  Bert

  A stock tray is fine and what I have used for years. I prefer open tray impressions so i cut out the tray to allow the long pins to extend thru the tray try in the tray to verify and modify further if needed. i also prefer putty in the tray and squirt some light body intraorally at the gingival aspect of the heads

  In my country we are always trying to save money in dentistry. And trying to save money while taking implant impressions is the most foolish counter-productive things we do here. The money you save in implant impressions is less compared to the ill fitting crowns that you have to repeat.

  Is your patient going to pay for the lab fees twice? I don’t think patient’s in any country are naive enough to pay for the same crown twice, when it wasn’t their fault.

  I sse no difference with a stock tray except in the amount of impression material used. I use putty or heavy body first to make three stop areas, them border mould with it. I now have a “custom tray effect.” Then take the final with medium or light body laid into this tray. Great impressions every time with no initial impression appointment, model and custom tray cost (lab or self made). There are actually stock trays made for this technique…cannot remember the name.

  For easy impressions, putty reline technique using stock tray can be made with openings in the tray to accommodate the transfer posts.As suggested by others the cost is not the criteria to be considered.

  No real clinical differences exist with different impression techniques, the criteria of selection depends on the type of prosthesis to be made and the number of implants.

  I replaced a non-restorable tooth #8 with an immidiate implant and bone graft along with resorbable membrane. Pt. has diastema and wishes to close the space. # 8 is in the correct position relative to the midline, and so I want to move #9 orthodontically misially for 2 mm. Since we do not want to disturb the bone graft site and we will have osteoclast activity on the mesial #9, should I wait for ortho movement or this will not have a negative effect on healing of bone graft. Thanks for your respons

  The new Strong-Massad DenPlant impression trays were specifically developed to solve these issues. These are clear, disposable, economical, heat-moldable trays that can be used for all of your implant overdenture, implant fixed, partial denture, and crown and bridge impressions. They are available through all major distributors including Patterson, Schein, Burkhart, Benco, Leemark Dental Supply, etc. The trays are far more cost effective and more accurate than traditional custom trays because they can be molded in the mouth to become a custom tray.
