Immediate provisional implants as abutments for an overdenture in the mandibular edentulous jaw: case presentation.

Based on the need for provisionalization to provide sufficient phonetics, adaptation, and function following implant therapy, simultaneous placement of immediate provisional implants has evolved to allow abutment positioning following initial surgery. This modality allows the patient to be restored with a stable, functional, and aesthetic restoration during soft tissue healing prior to the removal of the provisional implants. This article presents the clinical protocol for treatment of the edentulous mandible using an immediately provisionalized implant supported overdenture.

Construction of a custom-shaded interim denture using visible-light-cured resin.

A patient treatment is presented to demonstrate a technique using visible-light-cured (VLC) resin to create a characterized denture base for an interim denture. This indication for characterization is routinely seen with African-Americans with dark-pigmented gingiva. Using a combination of blue VLC tray resin and pink VLC denture base resin, the mixture achieves a darker-colored denture base. This technique was used for the fabrication of an interim denture for a patient who required an immediate interim denture. The prosthesis was worn during the healing phase and allowed the patient to function while the definitive prosthesis was being fabricated.

All-on-4 immediate-function concept with Brånemark System implants for completely edentulous maxillae: a 1-year retrospective clinical study.

BACKGROUND: Immediate implant function has become an accepted treatment modality for fixed restorations in totally edentulous mandibles, whereas experience from immediate function in the edentulous maxilla is limited. PURPOSE: The purpose of this study was to evaluate a protocol for immediate function (within 3 hours) of four implants (All-on-4, Nobel Biocare AB, Göteborg, Sweden) supporting a fixed prosthesis in the completely edentulous maxilla. MATERIALS AND METHODS: This retrospective clinical study included 32 patients with 128 immediately loaded implants (Brånemark System TiUnite, Nobel Biocare AB) supporting fixed complete-arch maxillary all-acrylic prostheses. A specially designed surgical guide was used to facilitate implant positioning and tilting of the posterior implants to achieve good bone anchorage and large interimplant distance for good prosthetic support. Follow-up examinations were performed at 6 and 12 months. Radiographic assessment of the marginal bone level was performed after 1 year in function. RESULTS: Three immediately loaded implants were lost in three patients, giving a 1-year cumulative survival rate of 97.6%. The marginal bone level was, on average, 0.9 mm (SD 1.0 mm) from the implant/abutment junction after 1 year. CONCLUSION: The high cumulative implant survival rate indicates that the immediate function concept for completely edentulous maxillae may be a viable concept.

The fixed mandibular implant: a 6-year review.

In a review of 102 consecutive cases of the fixed mandibular implant there were no failures; all appeared clinically to be osseointegrated and functioning well. There were an unexpected number of gingival infections and instances of inflammatory gingival hyperplasia, but these have been reversible and manageable. A change in sleeve nut design has improved gingival health. The Fixed Mandibular Implant (Hall Reconstructive Systems, Carpinteria, CA) offers immediate denture stability and function, and provides the opportunity for a fixed, fixed removable, or overdenture prosthetic reconstruction.

Immediate loading of dental implants in the completely edentulous maxilla: a clinical report.

PURPOSE: The purpose of this article was to determine whether clinical success can be achieved with immediate loading in the completely edentulous maxilla with endosseous screw-type implants. MATERIALS AND METHODS: The study sample consisted of 34 patients who were edentulous or about to lose all remaining maxillary teeth. The patients underwent an extensive presurgical and prosthetic workup to determine whether they qualified for the study. Sufficient osseous structure to place 6 to 8 implants with a minimum length of 8 mm was required. Provisional prostheses were fabricated either chairside on the day of implant placement or in a laboratory from an impression. The abutments and temporary restorations were placed 48 to 72 hours postsurgery. RESULTS: A total of 236 implants were placed in 34 patients. Sixteen implants were lost in 11 patients; thus the survival rate was 93%. All patients subsequently received definitive maxillary restorations. DISCUSSION: The major cause of implant failure appeared to be micromotion during healing. This was the result of either a non-passively fitting restoration or noncompliance (eg, eating chewing hard foods before the implants had integrated). CONCLUSIONS: This clinical report suggests that immediate loading of implant-supported restorations in the completely edentulous maxilla was a viable treatment alternative for this patient population.

The OSU frame: a novel approach to fabricating immediate load fixed-detachable prostheses.

PURPOSE: Interest in the concept of immediate or early loading of dental implants is increasing. The survival of these implants, particularly in the anterior mandible, has been demonstrated in a variety of clinical reports for different implant systems. However, to make immediate loading a reality for the patient, the restorative dentist must coordinate care with the surgeon and the laboratory fabricating the prosthesis. This article describes a method that allows restoration of the edentulous mandible in 2 days. MATERIALS AND METHODS: Five implants were placed in the mandible and restored in 2 days with a final fixed-detachable prosthesis that was fabricated using the OSU Frame. There is little change to the surgical protocol whether the implants are loaded immediately or loading was delayed. The step-by-step technique is described. RESULTS AND CONCLUSION: There are several benefits to this method over those currently available. No changes in surgical armamentarium technique are required. The technique may be adapted to any implant system and it offers improved flexibility over the existing systems. The OSU Frame accommodates variability in arch form and suboptimal implant placement, facilitating immediate implant loading with the final prosthesis for nearly any edentulous implant patient.

[Fixation of complete lower prostheses with intra-alveolar implants (case report)].

The author describes a female patient in whom complete lower prosthesis had to be made for the first time. For improving the stabilization of the prosthesis had to be made for the first time. For improving the stabilization of the prosthesis and facilitate the adaptation it was planned to carry out intra-alveolar implants by Wierzyński's method inserted into freshly emptied alveoli. The immediate prosthesis was a specially adapted prosthesis which had been worn previously by the patient. After healing of the post-extraction wound and epithelialization of alveoli final prosthetic replacement was prepared, i.e. upper partial prosthesis and lower complete prosthesis with intra-alveolar implant.

Immediate loading of implants with mandibular overdentures: one-year clinical results of a prospective study.

PURPOSE: The aim of this report is to present the implant and clinical outcomes of an immediate-loading protocol of TiUnite implants with mandibular overdentures in edentulous patients. MATERIALS AND METHODS: Two groups of edentulous patients were selected. Thirty-five consecutively treated patients received 70 immediately loaded TiUnite implants and 69 Brånemark implants as backup (1 patient received 1 Brånemark implant). The control group was a historical cohort that comprised 42 patients who received 111 Brånemark implants. All overdentures were supported by a resilient bar mechanism. Implant and clinical outcomes, including maintenance events for the first year, were recorded. RESULTS: Implant success rates were in excess of 95% with both protocols. Immediately loaded implants had less bone loss than did implants loaded with the conventional protocol (Mann-Whitney U test; P = .001). Patients in the immediate-loading group required more prosthodontic maintenance, consisting of overdenture remakes and laboratory relining of prostheses (Chi-square test; P < .05). Of note, 74% of patients in the immediate-loading group needed a reline to improve the denture seal around the bar housing (Chi-square test; P < .05). CONCLUSION: The favorable implant and bone level outcomes with immediate loading attest to its biologic success. The prosthetic maintenance encountered in the immediate-loading group does not negate the clinical potential of the treatment but rather suggests that the protocol may benefit from modifications.

Immediate loading of the edentulous mandible: delivery of the final restoration or a provisional restoration--which method to use?

PURPOSE: Edentulous patients desire restoration of their chewing ability as soon as possible after placement of dental implants. The purpose of this article is to provide clinicians with evidence that immediate loading of implants placed into the anterior mandible can predictably provide the patient with early functional rehabilitation. Two methods are presented that illustrate delivery of the final restoration or a provisional implant-borne prosthesis immediately after implant placement. MATERIALS AND METHODS: A literature search was performed which produced 14 articles in the English literature that provided sufficient evidence that immediate loading is now not experimental and can be recommended as an acceptable treatment alternative. RESULTS: Two practical methods to achieve immediate function are presented in a step-wise manner to illustrate how to deliver this service to the patient. CONCLUSION: Based on our literature review, immediate loading of the edentulous mandible with an implant-borne restoration is an acceptable and predictable method to deliver efficient return of function for the edentulous patient.

The retention of vital submucosal roots under immediate dentures: a surgical procedure.

An approach to soft tissue management and surgical crown/root sectioning for submucosal vital root retention has been presented. Attention to detail during soft tissue reflection, tooth sectioning, and the relaxing of attached mucogingival tissues is very important. Adequate healthy soft tissue is necessary for proper suturing over the retained roots. Postoperative complications are reduced by placement of well-fitted prostheses. Clinical evaluation of this technique has proved it to be highly successful.

Zygomatic implants--protocol for immediate occlusal loading: a preliminary report.

PURPOSE: To investigate the modified protocol for immediate occlusal loading of the zygomatic implants and to report the preliminary results of this modified protocol. MATERIALS AND METHODS: Four male patients and 1 female patient with edentulous maxillae were consecutively treated with the zygomatic implants under general anesthesia. All 5 patients were examined by computed tomography and investigated by the SimPlant software (Materialise NV, Leuven, Belgium). Based on the virtual surgical plans, mucosa-supported surgical guides were manufactured by rapid prototyping technique before implant operation. Instead of making a Le Fort I Osteotomy incision or a crestal incision, buccal vestibular incision was used to expose the surgical site for the zygomatic implant osteotomy and placement. Three patients had their remaining upper teeth removed on the same day as implant placement. One patient had undergone simultaneous placement of upper and lower implants followed by immediate loading. The immediate loading protocol was a 2-stage method using a customized provisional fixed prosthesis. RESULTS: Ten zygomatic implants and 20 normal implants were installed in these 5 patients. These 5 patients were reviewed regularly for 6 to 10 months after immediate loading. The zygomatic implants were considered to be successful when they were asymptomatic with no clinical mobility and no sign of infection. All the zygomatic implants and normal implants were investigated individually after removing the provisional prosthesis and were found to be clinically stable and asymptomatic. CONCLUSION: According to our observation, immediate occlusal loading of the zygomatic implants has a very good potential for success, as much as immediate occlusal loading of normal dental implants. The surgical placement of the zygomatic implant is simplified and facilitated by making use of the computer-assisted planning and the rapid-prototyping surgical guides.
