Dental implants in the diabetic patient: a retrospective study.
It has become increasingly common for controlled diabetic patients to be considered as candidates for dental implants. This study reports on the results of placing implants in 34 patients with diabetes who were treated with 227 Brånemark implants. At the time of second-stage surgery, 214 of the implants had osseointegrated, a survival rate of 94.3%. Only one failure was identified among the 177 implants followed through final restoration, a clinical survival rate of 99.9%. Screening for diabetes and trying to ensure that implant candidates are in metabolic control are recommended to increase the chances of successful osseointegration. Antibiotic protection and avoidance of smoking should also be considered.
Osseointegration treatment of transverse root fractures in the region of the alveolar crest.
A method of using osseointegrated implants as an alternative treatment modality for transverse root fractures near the osseous crest is presented. A 15-mm Branemark implant was placed immediately after extraction of a maxillary central incisor with transverse root fracture. Five months after stage I surgery, the implant was uncovered. Custom fabrication of a substructure core cast directly to the titanium single tooth abutment was necessary due to the palatal inclination of the fixture. An overcasting porcelain fused to gold crown was fabricated to avoid an unesthetic labial access for the abutment screw. This treatment indicates that the use of osseointegrated implants seems to provide an effective solution to replacing teeth with transverse root fractures.
Immediate loading of Brånemark implants in edentulous mandibles: a preliminary report.
A study involving the immediate loading of Brånemark implants in the edentulous mandibles of 10 patients is reported. The design involved the immediate loading of four widely distributed implants with a transitional fixed implant-supported prosthesis at first-stage surgery, avoiding the need for a removable prosthesis. A sufficient number of additional implants are allowed to heal in the conventional manner to provide sufficient support for a definitive fixed prosthesis even if all of the immediately loaded implants fail. Preliminary results have been favorable, with all patients functioning with a fixed implant prosthesis from the day of first-stage surgery.
Fabrication of acrylic resin copings for CeraOne provisional restorations.
A technique is described for fabricating autopolymerizing acrylic resin copings for CeraOne provisional restorations. This method has the advantage of providing a chemical bond rather than only a bond between the mechanical coping and the relined provisional crown, as is the case when using the provisional components supplied by the manufacturer. The technique describes provisionalization at the time of stage II surgery. This type of coping can also be used after a period of soft tissue healing when a healing abutment is employed. The benefits of the procedure include increased patient satisfaction and reduced chair time for repairs.
Two-implant-supported single molar replacement: interdental space requirements and comparison to alternative options.
Posterior single-tooth implant restorations are subjected to an increased risk of bending overload. A high incidence of implant fracture has been reported when using a single standard 3.75-mm-diameter implant to support a molar restoration. The purpose of this article is to demonstrate the clinical feasibility of placing two implants to support a molar restoration and to compare this treatment option to the use of a single standard implant or a wide-diameter implant. Two osseointegrated dental implants used to support a molar restoration in interdental spaces as small as 10 mm is shown to be effective and predictable in 60 restorations over the past 7 years. The use of two implants provides more surface area for osseointegration and spreads the occlusal loading forces out over a wider area, reducing the potential bending forces that would otherwise exist in a single-implant molar restoration.
Implant rehabilitation of a patient after partial mandibulectomy: a case report.
Radical surgery was performed to remove the left side of the mandible in a patient diagnosed with mandibular carcinoma. For 36 years, the patient functioned with a hinged, removable partial denture anchored to the remaining natural dentition on the mandibular right side. Because of deterioration of the remaining natural dentition, the patient could no longer function with the partial denture. In lieu of reconstruction with a bone graft, the patient chose to undergo treatment with osseointegrated implants to permit insertion of a stable prosthesis with a cantilevered extension into the area of the surgical resection. The rigid attachment of the prosthesis to the remaining mandible provided function as well as soft tissue support in the area of the surgical defect.

Candidates and requirements for single tooth implant prostheses.
Successful prosthodontic treatment begins with an accurate diagnosis and thorough and comprehensive treatment planning. Osseointegration is an integral part of prosthodontic treatment planning. When use of the single tooth implant is anticipated, there are several procedure objectives that should be considered: elimination of pathosis; attainment of ideal fixture alignment and stability; protection of teh adjacent teeth; preservation or augmentation of the alveolar ridge; attainment of primary closure; and avoidance of mucosal pressure. Esthetic and biologic complications are discussed.

Osseointegration and orthodontics: modern treatment for congenitally missing teeth.
Among the goals of orthodontic therapy is the establishment of optimal facial form, occlusal function, and dental esthetics. Orthodontic treatment of patients with congenitally missing teeth, especially maxillary lateral incisors, can be accomplished best by positioning the remaining natural dentition in the anatomically correct location and closely coordinating therapy with the osseointegration team members. Special divergence of adjacent root tips is essential to provide space for the implant. The Brånemark system of implant therapy is the treatment of choice for the permanent replacement of congenitally missing teeth.

Single, tuberosity-osseointegrated implant support for a tissue-integrated prosthesis.
Fixed prosthodontic rehabilitation can be accomplished in partially edentulous patients whose maxillary antrum prohibits successful placement of multiple fixtures. A single posterior fixture is placed in the tuberosity region to support a tissue-integrated prosthesis directly connected to a periodontally sound anterior abutment tooth. The treatment planning considerations and surgical aspects are described, and a case report is used to illustrate the technique.
Osseointegrated Brånemark implants used to retreat a fractured mandibular bone plate staple implant: a case report.
This article describes postimplant follow-up and retreatment of a 66-year-old patient with an esthetically compromising fixed maxillary tissue-integrated prosthesis and a mobile mandibular overdenture stabilized by precision attachments with a gold clip bar cemented to the transmucosal posts of a bone plate staple implant. Following successful completion of prosthodontic treatment, the patient returned with a fracture of the left transmucosal pin in the mandibular bone plate staple implant that was retreated with Brånemark implants and a fixed prosthesis.
Oral prosthodontic rehabilitation for traumatic sports injuries.
Sports injuries to the mouth and oral cavity may be treated with a variety of prosthetic treatment methods. These may include a temporary removable appliance, especially when adjacent teeth are unrestored and free of caries. Other traditional forms of prosthetic rehabilitation can range from conventional clasped removable partial dentures to traditional fixed prosthesis. The use of clip bar overdentures has demonstrated their clinical acceptability, especially for athletes involved in contact sports. The optimal treatment for patients suffering tooth loss, however, is the use of the osseointegrated implant. This concept, developed and refined by P.I. Branemark, permits successful replacement of single as well as multiple lost teeth. Criteria for patient selection must be evaluated carefully, especially for immediate fixture placement in sockets of avulsed teeth. Professional athletes in high-impact contact sports should receive a resilient prosthesis and protective appliance to use during the sport season, followed by a screw-retained nonremovable prosthesis to be used in the off season. Considering all forms of prosthodontic treatment available to patients with missing teeth, the use of osseointegrated implants currently appears to be the most biologically conservative approach. Retrospective studies document the effectiveness of the treatment of partially edentulous jaws, results similar or better than those reported for fully edentulous patients indicate the effectiveness of the Branemark method of osseointegration.
