Both fixed and removable implant-supported prostheses are well-established methods for replacing missing teeth in partially or fully edentulous patients. Numerous systematic reviews have been performed in recent years to evaluate the survival and complication rates of implant-retained fixed dental prostheses and implant-retained overdentures, displaying high 5-year survival rates ranging from 97.1% for fixed dental prostheses to 95%-100% for implant-retained overdentures. However, the survival rates only represent the prostheses remaining in use for a defined follow-up time, and do not account for the potential prosthetic complications that may have arisen and influence the general success of the implant treatment. The most common technical complications of fixed implant-retained single crowns are crown fracture, fractures of ceramic implant abutments, and esthetic problems. The predominant technical complication at multiple-unit, implant-retained fixed dental prostheses is fracture/chipping of the veneering ceramic. Reported technical complications for implant-retained overdentures are overdenture fracture or chipping of the veneer materials, whereas mechanical complications include implant fracture, attachment failure, and attachment housing or insert complications. To reduce the risk of such failures, a comprehensive pretreatment diagnostic work-up is essential, including defining the prosthetic goal with the aid of a wax-up or set-up and the associated ideal, prosthetically oriented three-dimensional implant position. Furthermore, selection of the ideal type of prosthesis, including the respective implant components and materials, is important for clinical long-term treatment success.
The number of implants used to support a completely implant-supported restoration in the edentulous mandible usually ranges from 5 to 9 in the mandible, with at least four of these implants inserted between the mental foramens.
A greater implant number in the completely edentulous maxilla is indicated to compensate for the less dense bone and more unfavorable biomechanics and ranges from 6 to 10.[22] At least two or three of these implants should be placed in the premaxilla, depending on the arch shape and other force factors.
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.
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.
