The role of the implant abutments, in simple terms, is to provide a connection (with a screw) between the implant and the crown (providing support) of the tooth. Other than the various materials used to produce the abutment, there are two additional categories: Stock dental abutments and custom implants.
Stock abutments are produced according to standard measurements and sizes, they can be used both for bone level or tissue level implants. They are produced from the get-go to fit general cases for the mass public according to set heights, sizes and standard materials.
What Is The Purpose of the Stock Implant Abutment?
Their purpose is to provide an easy and friendly use, to save time and are more economical than custom made implant abutments and are usually used for restoration that are cement retained. Moreover, stock abutments can be produced either straight or at a certain angle depending on the location of the dental implant and the specific patient’s mouth. Stock abutments are usually more favorable to use in locations of the mouth that are less visible, this is due to the fact that tissue will comply to the shape of the dental dental abutment.
If a stock abutment would be used in a more visible location on the mouth, it would be a challenge to create a natural appearing emergence of the crown contour which is relative to the adjacent teeth. An additional issue with a stock abutment would be the final placement of the crown may not be precise or easy to control as it is dependent on the height and depth of the abutment and implant.
What are the benefits of Custom Made Implant Abutments?
Custom abutments, on the other hand, can be used for tissue or bone level, they are pre-milled or casted in advance according to the exact positioning specific to each client's needs and dimensions, which is relatively placed to the tissue crest. There is a large variety of options for custom abutments, pre-milled from materials such as zirconia, titanium, PEEK and more.
There is an ongoing discussion regarding the strength of various materials, which will withstand the daily use inside a patient's mouth. The material that seems to situated at the top of the ladder at this time is the titanium abutments vs. the zirconia. This should not come as a surprise, as the choice of using a zirconia abutment will usually be done when the dental implant is significantly lower than the gingival tissues and there is a potential that the abutment will extend to the implant when the collar is metallic. Then there is a higher chance that the grey completion of the metallic abutment will show through the gingival tissue.
Moreover, in situations where one plans on using an all-ceramic based crown, it is best to use a zirconia abutment which will provide a far more pleasing esthetic outcome than the metallic option.
Although custom abutments are more expensive as they are designed and produced to the exact measurements and needs of each specific client and, they do provide better accuracy, better aesthetic results as well as a more natural final outcome. In some cases, the patient’s needs and dental health will not enable the use of stock abutments and then custom abutments will need to be used in order to provide the best results possible.
Exceptions in the dental field are not rare or few, which means that having the option of custom creating dental implant solutions are a necessity.
The technological advancements that have been made over the past decade have been so substantial, providing not only better and more biocompatible materials to work with that have decreased cases in which patients have negative reactions to the dental implants and abutments. There have, moreover, been massive improvements in patient recovery times, aesthetic outcome satisfaction, as well the option to conduct dental procedures chair-side, decreasing the number of visits a patient needs in order to complete their treatment.
We are here to provide you with information about Dental Implant Abutments. Each category provides a specific purpose during the dental implant process, each befitting to the various dental cases of different patients that visit the practice.
