Introduction. The mechanical stability of implant-supported fixed restorations may be considered to improve long-term stability and minimize complications1. The stability of the connection between different implant parts is important for the success of the rehabilitation, especially for single tooth restorations. Loosening of abutment screws, mainly with the external hex implants, has been a technical problem that occurs in the first two years of use2. The stability of the external implant-abutment connection has been improved by altering the screw alloys and their surfaces and applying proper torque values to establish higher initial preloads3-5 . A systematic review compared the complications of screw-retained prosthesis showing that the most frequent complication was related to abutment screw loosening (10-55.5%). The incidence of abutment screw loosening was 4.3% in short-term studies and 10% in long-term studies1 . Mechanical factors, such as the implant-abutment fit and the abutment screw ...
Results During the observation period (2 - 5 years), abutment screw loosening was found in 29 restorations (7.4%). It took 3 to 48 months (means 19.5 months) to loose the screw, and three of these implants were fractured. Among the factors considered, there were statistically significant differences at abutment screw loosening rate between molar group (9.4%) and premolar group (2.6%) (P,.019). According to the type of opposing teeth, there were statistically significant differences between nature teeth (74.7%) and implant (25.0%), removable denture (3%) (P,.019). The other possible factors did not have a significant effect on loosening of the abutment. ...

Implant Abutment SWOT Analysis And Forecast This report studies Implant Abutment in Global market, especially in North America, China, Europe, Southeast As
Implant-supported single crowns have become a valid alternative to conventional fixed dental prostheses due to their excellent clinical long-term results. However, along with good survival rates, esthetic factors are important for success in anterior regions. Today, several kinds of implant abutments are offered by implant manufacturers. A choice must be made between standardized and customized abutments; further, different abutment materials such as titanium or various ceramics (alumina, zirconia) are available. Finally, the reconstruction can be cemented on the abutment or screw-retained directly on the implant. When choosing an abutment for an anterior single-unit case, several factors should be considered: visibility of the region (eg, high vs low smile line); biotype of the gingiva; color of the neighboring teeth; and finally, esthetic expectations of the patient. In esthetically demanding situations, customized ceramic abutments are indicated. In patient situations with thin peri-implant ...
Posted on July 12, 2017 in Integrated Abutment Crowns™, SHORT® Implants. This treatment demonstrates the insertion of a 4.0 x 6.0mm implant and a 4.5 x 6.0mm implant into two contiguous mandibular osteotomies, which communicated with each other because of a bone void. After preparation of the implant osteotomies through the crest of cortical bone, the soft tissue content of the bone void was thoroughly removed from the bony walls of the defect with a spoon excavator prior to filling the defect with a putty-like consistency of the patients blood and SynthoGraft®, a pure-phase beta-tricalcium phosphate. A sinus lift abutment was used to prevent the implants from being displaced into the defect. Subsequently, the implants were restored with Universal Abutments and Integrated Abutment Crowns (IACs).. ...
Dr. Emil Svoboda - Preventing Peri-implant Disease by Safer Prosthesis Installation Preventing Peri-implant Disease by Safer Prosthesis Installation: Managing the Macrogap and Residual Subgingival Cement. Emil LA Svoboda PhD, DDS November 6, 2017 Dental implants are used in dentistry as tooth root replacements that can be used to retain replacement teeth. Dental implant abutments are used to connect dental implants to the dental prosthesis. The implant-abutment connection is often located in the deep subgingival space, close to the alveolar bone adjacent to the dental implant. There is much research that discusses the importance of the fit of the implant-abutment connection. Indeed, the fit of this joint is critical to its stability during oral function and its ability to prevent penetration by oral pathogens. Read.... ...

Top ] What Loads Will the Restored Tooth Experience. The load borne by the restored tooth is a major indicator of the success of a restoration. Sorensen and Martinoff29 found in their retrospective study that while the success rate for single unit crowns was 94.8%, the rate was 89.2% for fixed partial denture (FPD) abutments and dropped to 77.4% for removable partial denture (RPD) abutments (both distal extension and tooth born designs). Nyman and Lindhe30 found fractures in abutment teeth occurred more frequently in root treated teeth, and primarily in root treated teeth fitted with posts, serving as terminal abutments for free end segments. Hatzikyriakos et al31 found in a three-year retrospective study that the failure rate for endodontically treated teeth used as abutments for FPDs and RPDs was over double that for teeth not used as abutments.. Testori et al32 recommended against anchoring a cantilever bridge on an abutment that was endodontically treated and fitted with a post. Testori also ...

Start of standard prosthetic procedure. In this study we expect that the soft tissue attachment (i.e. the gingival attachment) will be stronger and earlier achieved at the nano-structured healing abutments than at the normal, uncoated healing abutments. This would lead to a more stable soft tissue complex on the long rung and thus providing a more predictable aesthetic outcome. Secondly, a stronger attachment would mean a stronger barrier against micro-organisms and might influence the occurrence of peri-implantitis ...
Materials and Methods: The present study was designed as a prospective stratified randomized controlled clinical trial. Patients were scheduled to receive two implants with different types of abutments in the posterior mandible. Three months after implant placement, titanium and zirconium abutments were connected. Five weeks after abutment connections, the abutments were removed, probing depth measurements were recorded, and gingival biopsy samples were obtained. Abutments and biopsy specimens were analyzed by reverse-transcriptase polymerase chain reaction to compare the DNA copy numbers of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and total bacteria. The surface free energy of the abutments was calculated by sesile water drop before replacement ...
First of all, a bridge is a prosthetic tooth (or teeth) that attaches on one or both sides to teeth prepared with dental crowns. A fixed bridge is joined onto the neighboring abutment teeth (crowned teeth) and consists of three basic units: the false tooth or teeth (called a pontic) and two abutment crowns. If healthy adjacent abutment teeth arent available, a surgically-implanted metal post, known as a dental implant, may offer a solid alternative. For a bridge that replaces many teeth, we may recommend a removable partial denture or implant-supported prosthesis. ...
Objective: The purpose of this study was to conduct a postmortem examination of retrieved failed dental implants to identify design characteristics that may have contributed to premature loss. Method and materials: Forty-five failed implants retrieved from 40 patients with no significant risk factors for implant failure (eg, history of smoking or diabetes) were examined by scanning electron microscopy. All implants were placed by general dentists or periodontists in private practice and had functioned for an average of 4 years. Results: Several design features of currently used implants present plaque-retentive areas. Plaque accumulation occurred along the implant/transmucosal abutment interfaces, transmucosal abutment/prosthesis interfaces, implant-prosthesis interfaces, and on surfaces of the abutment, the implant, and the prosthesis. The size of the microgap between the various components, the degree of surface roughness of the restorations and abutments, the exposure of plasma-sprayed ...
The excess cement not removed following the cementation of fixed implant-supported restorations may cause loss of peri-implant attachment or adjacent bone. The aims of this study were to evaluate the amount of residual cement at different abutment-crown connection levels and to test the cleaning efficacy of poly-ether-ether-ketone (PEEK) ultrasonic tips after cementation. One implant was placed in an anterior central tooth position 5 mm below the gingival margin in an acrylic model, and 32 stone models were obtained with implant analogs. Abutment heights of 1-2 mm and 2.5-4 mm were used on the vestibular and lingual sides, respectively. Crowns were cemented and cleaned, and half of the samples were cleaned again using PEEK tips. The abutment-crown suprastructure was then disconnected, and cleaning efficacy was evaluated. Varying amounts of excess cement were found on all specimens except for the PEEK group with abutment-crown connections 1 mm below the gingival margin. An increase of undetected ...
Immediate Loading Protocols , Determining Primary Stability » Interview conducted by Gary J. Kaplowitz, DDS, MA, MEd, ABGD. OsseoNews (ON): In your protocol you connect the provisional fixed partial complete denture to the abutments that have been permanently torqued down into the implant fixtures. What is your technique for accomplishing this?. Dr. Balshi: After the abutments are torque down, we insert a prosthetic cylinder over the abutment. We then screw down the cylinder with guide pins which project well above the height of the cylinders. We relieve the prosthesis in the area of the abutment and cylinder and cover the abutments with rubber dam fragments to block out any undercuts. We then deliver acrylic around the cylinders and insert the prosthesis. The acrylic locks the cylinder into the acrylic veneer. We unscrew the guide pins and then adjust and polish the surface of the prosthesis. The prosthesis is then ready for delivery.. ON: How do you manage a situation where you place an ...

Dental bridges are a great way to replace missing teeth. Your existing teeth are used to literally create a bridge to cross the area where your tooth is missing. Bridges are made from gold, metal, alloys, or porcelain to ensure that they are strong and durable.. The process of creating a bridge begins by creating abutments out of your existing teeth where the bridge will be attached. The existing teeth are recontoured to provide a base for the bridge. After the abutments have been created, a mold is taken of the area which is sent to a dental lab. The lab is able to use the mold to create a bridge that will fit properly and feel as close to your natural teeth as possible. The bridge consists of two crowns on either end to place on the abutments and a pontic, which is the new tooth that replaces your missing tooth.. ...
Apparatus to remove tissue. The apparatus has an outer cannula and an inner cannula received within the outer cannula. The cannula are longitudinally movable relative to each other. There is an abutment at the end of one cannula to contact the other cannula. A drive permits advancing of the other cannula to contact the abutment whereby tissue between the other cannula and the abutment is removed. The invention finds particular application in removable of lens tissue from the eye of a human or other animal.
The disadvantages include the requirement of grinding and crowning the abutments. This drawback is offset by the circumstances in which the abutment teeth no matter what were intended to be crowned because of other indications (see indications for prosthetic crowns). Then, by the way, prosthetic crowns planned to rebuild the missing tooth or teeth as prosthetic bridge are used.. Another disadvantage of prosthetic bridge is common to all dental restorations with the exception of the implants. It is the disappearance of the appendix marrow under the bridge span so in a place deprived of direct stimulation of the chewing forces. Bone, like any living body, requires stimulation and when there is a lack of stimulation, it gradually fades. It is a natural feature of a living organism. Under natural conditions the bone stimulation is provided by the forces acting on the tooth and transmitted through its root. Lost of a tooth means the lack of stimulation in the area. Accordingly, it comes to the bone ...

spark erosion technique. -milled/ cast bar, cast suprastructure with set screws. -milled bar with individual abutments and single crowns cemented on the abutments (13,14).. The substructure/suprastructure design has its advantages and disadvantages.. Some of the advantages of this type of design include providing the patient with a fixed prosthesis when no other designs are feasible. It also has the ability to replace both missing hard and soft tissue and improve unfavorable biomechanics seen in off-ridge relations (15). Esthetics and phonetics are usually very good with this type of design.. However, there are also disadvantages to this design.. The cost is usually very high due to precise and complicated laboratory procedures that are required and it unfortunately can be prohibitive for some patients. Passive fit of the bar and framework is also difficult to achieve. Long span frameworks are difficult to apply porcelain to and porcelain fracture is challenging and costly to repair. Also, loss ...

When a tooth is missing and the patient is motivated to replace it, an implant is an ideal treatment, provided there is appropriate amount of healthy bone in which to place it. The implant itself is a screw-like cylindrical construct made out of titanium, ceramic or both which serves as the replacement of the tooth root. Once the bone has integrated with the implant surface, the implant is ready to be restored. An abutment is secured into the internal screw inside the implant and sits above the gumline as if it were a tooth that had been shaped for a crown. Then impressions are taken and a crown is fabricated and cemented onto the abutment. When this process is completed, the patient has a "tooth" which is not only functional, but is also not susceptible to decay.. Implants can also be used to support multi-unit bridges and to "snap" down dentures.. The critical step to the success of implant therapy is treatment planning. Implants should never be placed at the convenience of a surgeon who has ...

It is important to understand that there are patients who are not suited for or who are too young to receive an implant. Poor hygiene significantly increases the risk of adverse skin reactions. It is vital to be able to maintain proper hygiene around the abutment. Factors that affect this ability should be considered, as well as the possibilities of obtaining help to maintain sufficient hygiene if necessary. In children the responsibility falls on the parents or caregiver. Inability to maintain, or lack of help with maintaining sufficient hygiene around the abutment, is a contraindication for use. Patients with insufficient bone depth and bone quality have an increased risk of implant failure and potential need for revision surgery. Disease, history of irradiation or other factors that may affect the bone quality should always be considered in the individual surgical planning and assessment of the patient, before choosing to place an implant. Children must have sufficient bone volume and bone ...

A skin pricker for blood sampling has a barrel housing a lancet which can be pushed back against a spring to a primed condition, by an elongate cap over its needle tip there to be held by a trigger. The cap (4) is removed by twist and pull action. The lancet body has integrally formed spring arms extending rearwardly and alongside, and when the lancet is fired these are momentarily flexed inwardly as their tips snap past abutments within the barrel. These act as ratchets, providing a first defence against re-priming of the pricker. If that first defence is overcome by a substantial rearward force on the lancet, the spring arms rearward pointing Vs which wedge between the abutments and the lancet body. The cap may have a weakness leaving it rigid enough for the initial priming but which causes it to buckle if used to try to overcome the ratchet.
