Dental implants are becoming an increasingly popular alternative for patients who need to have teeth replaced. As a direct result of this, a growing number of medical professionals are devoting both their time and their resources to the pursuit of cutting-edge education and the purchase of cutting-edge technology. When it comes to providing patients with dental implant therapy, the confidence of the treating physicians is boosted by their experience with one or two prefered implant systems and components. The components used in treatment are continuously evolving as a direct result of the development of new treatments. The implant abutment is extremely important because it acts as the interface between the prosthetic repair and the implant itself. Implant abutments are required to have outstanding resistance to corrosion, strength over the long term, a high level of stability, and biocompatibility. In the past, clinicians generally relied on stock abutments, despite the fact that the use of custom-milled abutments is becoming increasingly widespread. It should come as no surprise that individualised abutments, particularly in the process of restoring anterior teeth, offer a number of benefits.
The advantages of abutments that have been machined to the customer's specifications are manifold:
1. They make it easier to get a comfortable passive fit.
2. The final restorations are fabricated in line with the patient's precise gingival architecture in order to obtain both an excellent emergence profile and a more cosmetically acceptable result. This is done in order to achieve an optimum emergence profile.
3. The angulation of the implants can be adjusted with greater ease.
4.A dental practise can run more effectively if there is a reduction in the number of chair-side adjustments that are required and if sessions are conducted in a more streamlined and expedient manner.
Zirconia and titanium are two materials that can be machined into bespoke abutments.
When it comes to manufacturing custom abutments, there are a few different approaches that can be taken. The CADCAM manufacturing technologies are utilised in the most common approach, which is also the most popular approach. In the past, personalised abutments were created by inserting a wax-up into a plastic sleeve, which allowed the technician to shape the wax-up into the desired form for the abutment.
Because of advancements in computer-aided virtual design technologies, the wax-up is no longer required in the design process. Instead, the imprint taken at the implant level, which also takes into account the shapes of the soft tissue around the implant, is used to generate the master cast. The opposing cast as well as the master cast are electronically articulated with the use of design software, which scans both casts. Using virtual design, the technician is able to create an abutment that is customised for each individual patient. By utilising design technology, even the construction of virtual crown shapes can be done in order to drive the design of the abutment. This allows the technician and the physician to view every anatomic detail of the finished restoration. After the design has been completed, the digital files are loaded into a milling machine, which turns a titanium rod or blank into the custom-made abutment. The use of virtual files enables the generation of several abutments, which enables the technician to provide the patient with an aesthetically pleasing interim crown while keeping a duplicate of the original file for use in the completion of the repair. However, in the long run, this mode of treatment would result in higher expenses, not only for the patient but also for the practitioner.
After being machined, an abutment made of titanium can, if necessary, undergo the hand finishing process. The amount of finishing that is done will be determined by whether or not the abutment was created with its retentive grooves and surface anatomy already there, or whether or not they will be formed before polishing. When it comes to surface treatments, CADCAM technology is typically superior to manual polishing in terms of performance.
Titanium nitride coating, which gives titanium abutments a golden hue, is an additional option for coating titanium abutments. A surface with a gold tone is often prefered by clinicians when aesthetics are the most important consideration. Because of the thin tissue, the naturally coloured titanium abutment is able to be seen through the gingival edge, which is detrimental to the treatment's overall cosmetic effect. The utilisation of a titanium abutment that is painted gold ensures that the gingival tissues will not turn a darker shade over time. However, not all types of all-ceramic crowns may be utilised with this particular type of abutment placed below them. It is not suggested to utilise titanium nitride-coated abutments with e.max crowns or zirconia restorations that have a considerable degree of translucency.
Zirconium rods are another option for fabricating abutments that are machined to a certain specification. Zirconia abutments are gaining in popularity and may be a good option in some circumstances, such as when the patient has weak gingival tissues and the importance of aesthetics cannot be overstated.When creating crowns and bridges, it is possible to make use of materials with a higher degree of translucency if tooth-colored abutments are utilised.
Titanium trioxide is added to the zirconia before it is fabricated into bespoke abutments so that it will be more stable. Because of the high mechanical properties it possesses, this stabilised zirconia is an excellent choice for usage in the mouth. The properties of stabilised zirconia are comparable to those of stainless steel, and it has a flexural strength that ranges anywhere between 1200 and 1300 MPA. PFMs, on the other hand, have a flexural strength that is around 1400 MPA. Stabilised zirconia can be coloured to look like actual teeth, and it can endure the cyclical pressure and stress that natural teeth are subjected to. Zirconia abutments have a lesser risk of causing an inflammatory reaction compared to titanium abutments, and they may be less harsh on peri-implant issues.
Custom abutments provide a solution that is both practical and effective for dental practitioners who are aiming to get the greatest possible treatment outcome for their patients. They help clinicians to establish a more advantageous emergence profile by meticulously controlling the soft tissues, which is necessary for the procedure. When gingival tissues are formed in the appropriate manner, it is simple for the patient to practise good oral hygiene. Patients frequently consider dental implants to be premium treatments; hence, they anticipate receiving implant restorations that are up to par with the standards they have set for them. Specially machined abutments make it possible to have implant-supported restorations that perform exceptionally well and have a pleasing appearance. Better results with implant treatment are quite likely to be noticed by physicians who make the switch from stock abutments to bespoke abutments.
