If you are reading this article, perhaps your dentist recently mentioned that you might need a dental implant prosthetic. This phrase may sound a bit intimidating at first, but rest assured that it is a simple and common solution to many different dental health and cosmetic issues.
When it comes to dental implants, however, a prosthetic refers to an artificial tooth. By definition, a prosthetic is an artificial part of the body, and when you are discussing a dental implant prosthetic, you are referring to two different parts, the metal insert that connects to the jawbone and the actual tooth itself.
In most cases, the metal that a dentist inserts into your jawbone when you are getting a dental implant will be made of titanium oxide. Titanium is the preferred metal for two main reasons: It is a strong metal that provides durable support for your implants, and it fuses naturally with the jawbone. Unlike other metals, titanium oxide will not corrode inside your mouth or react with bodily fluids. This allows it to form a bond with your jawbone and create a strong base that your implant needs to stay in place.
Generally, your dentist will use a porcelain crown to go along with the titanium abutment, and strength is again one of the biggest reasons. Not only does porcelain look and feel like a real tooth, but it is even stronger than a real tooth. One of the biggest benefits to dental implants over dentures is bite quality. While dentures struggle to come anywhere close to the performance of real teeth, dental implants perform on par or even better than real teeth, allowing you to get back to enjoying healthy foods that can protect the rest of your natural teeth!
Generally, dental implants are available to anyone who has enough bone density in their jawbone to be able to support the connection between the jawbone and the abutment. If the jawbone is too weak to support a connection, the implant will fail. When you opt for dental implants, your dentist will check your current oral situation to make sure your jawbone can support such a procedure. Your dentist will only proceed if they are sure that your jawbone is able to support the implant, which is one reason that dental implants have such a high success rate.
If you think you would be a good candidate for dental implants, then you should speak to your dentist. Be sure to let them know you would like to learn more about dental implants and how they can help you improve your oral health; your results will be something to smile about!
The BioHorizons conical, internally hexed connection features a number of unique design advantages focused on strength, durability and usability. The mating surfaces of the implant, abutment and abutment screw create a strong and durable precision fit as well as a predictable seal that isolates the inside of the implant from the oral biological environment. Using authentic BioHorizons parts will ensure a precision fit between the prosthetic component and implant, avoiding costly component failures that may occur from using third-party prosthetics.
Vulcan Custom Dental is an advanced prosthesis milling center with a primary focus on dental implant restorations. Vulcan offers authentic BioHorizons CAD/CAM abutments, titanium bars and surgical guides. Their team of dedicated engineers and technicians are committed to providing high-quality dental implant solutions.
Introducing the all-new OD Secure abutment system. The OD Secure abutment uses the industry's lowest profile connection to attach dentures and partial dentures to dental implants. With cuff heights ranging from 0.5mm to 6mm, the OD Secure provides attachment solutions for even the most challenging cases. The abutment is designed for easy delivery using an .050\" hex driver and is color-coded to ensure that the abutment matches the implant platform every time.
BioHorizons offers a broad array of abutments for a wide range of indications and patient conditions including the versatile 3inOne abutment and the convenient Simple Solutions restorative system. Our conical abutment-implant connection and tight machining tolerances create a \"wedging effect\" that produces a biologic seal. Abutment screw loosening is avoided by the Spiralock thread design, the same design used in the orthopedic and aerospace industries.
Currently, tooth loss is optimally treated by dental implants; this oral rehabilitation method is safe and predictable, with a success rate of 89.7% after 10 years.8,9 The treatment of patients with T2DM using dental implants was previously controversial because of tissue changes related to hyperglycemia.9 Dental implants are currently considered a safe and predictable treatment for patients with diabetes, with a success rate similar to that of non-diabetic patients;9 however, some authors have reported differences involving short implants.10
Postoperative evolution was marked by few peri-implant or prosthetic stump complications. One implant was associated with inflammation in a prosthetic stump of a patient with relatively well-controlled T2DM (HbA1c level
The immediate placement of dental implants into infected sockets remains controversial. Some studies21 have shown no statistically significant difference in the risk of failure between dental implants placed immediately into infected sockets and dental implants placed into non-infected sites; conversely, other studies22 have shown a three-fold increase in the risk of failure following immediate dental implant placement into an infected socket, compared with placement in an uninfected socket. In our study, all immediately inserted dental implants exhibited osseointegration. This high success rate is potentially because dental implants were inserted in areas with minimal inflammation (related to marginal periodontium) and not in sockets with periapical infections. The extracted teeth had either extended coronal and radicular destruction or had no prosthetic utility.
A fixed prosthesis offers benefits from both a functional and esthetic point of view and may be regarded as quite similar to a patient's own natural dentition when compared to alternative treatment options such as complete dentures or implant overdentures. There is a significantly reduced bulk to a fixed prosthesis which is perceived to be more comfortable and since no mucosal support is needed, patients can chew with greater force and eat a wider range of foods. Fixed prostheses lead to a gain of posterior mandibular bone because of the adaptation to higher chewing forces whereas hinging overdentures lead to bone loss in the posterior regions. Patients report enhanced social confidence as a result and reported quality of life satisfaction scores are highest with a fixed implant prosthesis. With all fixed prostheses, the contour should be carefully shaped in order to allow for oral hygiene access as these prostheses cannot be removed by the patient for cleaning. When a fixed prosthesis is close to the oral mucosa, the prosthesis' surface should be smooth and highly polished.
This prosthesis type shows excellent clinical long-term results and until recently it has been the primary type of fixed implant prosthesis provided to patients. A metal framework is fabricated which attaches to the implants and which has been designed to incorporate mechanical elements to help retain acrylic resin and artificial denture teeth. The current technology also uses CAD/CAM to fabricate precision-fit frameworks. The final prosthesis is usually screw-retained and is relatively easy to retrieve if denture teeth or acrylic resin need to be repaired.
These prostheses simulate a typical ceramo-metal bridge made for natural teeth in the sense that a substructure is fabricated to provide both the attachment to underlying implants as well as an ideal porcelain thickness for long term durability. A full-contour wax-up of the framework is done. It is then cut back to create the ideal veneering ceramic thickness and then it is scanned. The scanned image is employed in a CAM process to create a metal framework from a ceramic compatible alloy. In some situations, the wax up may be cast in a ceramo-metal alloy but full-arch precision of fit is more difficult to obtain than with a CAM substructure.
A metal-ceramic prosthesis shows very good esthetics, as ceramic is more life-like than acrylic resin. One disadvantage of a metal-ceramic prosthesis is that ceramic chipping or fracture may occur and may be difficult to repair. The opposing occlusion should be invariably and scrupulously considered, especially if a parafunctional habit is suspected. If indicated, consider prescribing an occlusal guard for adjunctive protection of the applied dental materials.
Both types of prosthesis retention can give excellent long-term results, although the retrievability afforded by screw-retained prostheses clearly offers the safer and most versatile option. Nonetheless some dentists prefer the cementation protocol since this approach precludes visibility of access openings in the occlusal or facial surfaces of the artificial teeth. It should however be emphasized that any sub-mucosal extension of a prosthesis could predispose to an iatrogenic peri-implant inflammation with attendant marginal bone loss if all cement remnants are not removed. For full-arch prostheses a screw-retained design is recommended as any maintenance procedure or subsequent treatment can be performed more efficiently by removing the prosthesis; for example in the case of technical problems such as fracture of the veneering material or of abutment screws or treatment of mucositis and periimplantitis. The problem of screw access openings being located in esthetically relevant areas can be solved by using angulated abutments (i.e. Multi-unit abutments) or angulated screws channels. 59ce067264
