Computer-guided implant placement with immediate provisionalization: a case report.

Placement of dental implants in the esthetic zone is challenging for clinicians because of patients exacting esthetic demands and preexisting anatomy. This article presents an option for highly demanding surgical cases with the use of computer-guided implant placement and immediate provisionalization. This technique optimizes implant placement and soft tissue esthetics while providing the patient with an immediate fixed restoration.

Immediate fixture placement: a treatment planning alternative.

The rationale and possible clinical applications of an immediate fixture placement technique are described. Although this concept may be a somewhat radical departure from the conventional mandibular protocol, there are significant potential patient benefits with no apparent change in anticipated fixture survival rates. A similar approach in the maxilla may be less practical with most presenting dentitions, but there is evidence that further research may make immediate fixture placement equally appropriate in this arch.

[Dental prosthesis using immediate implants].

The authors emphasize the role of implantation in recovery of the maxillodental morphology and function and in the prevention of denture involvement in cases with removal of a tooth. Specific features of prostheses after direct implantation (implantation into removed tooth or root well) are described. Advantages of immediate implantation over delayed are enumerated.

[Resonance frequency analysis in immediate loading of dental implants].

Immediate loading of dental implants aims to shorten treatment time. Stability at implant insertion is critical to success. The aim of this prospective study is to compare primary implant stability, measured by insertion torque (IT) with resonance frequency analysis (RFA) expressed as ISQ. Patients requiring implant therapy were treated by teeth extractions, placement of 1-9 MIS implants, bone augmentation as needed and fixed provisional restorations. We measured IT and ISQ for non-submerged loaded (NSL), non-submerged non loaded (NSNL) and submerged (S) implants. 14 patients, aged 34-79 years, were recruited. 53 implants were inserted (38 maxillary & 15 mandibular). 30 implants, 18 in fresh extraction sites, were immediately loaded. ISQ was 63.3 +/- 2.8 (S.E.), 67.2 +/- 3.5 (S.E.) and 58.8 +/- 2.7 for the NSL, NSNL and S groups, respectively (p = 0.0459). IT was 40.4 +/- 1.8 Ncm, 46 +/- 4.0 and 35.3 +/- 2.1 (p = 0.0646). ISQ and IT were not statistically different between extraction vs. non-extraction and augmented vs. non-augmented sites. We found a significant difference in IT between maxillary & mandibular sites, and a significant correlation between ISQ & IT and between ISQ & implant diameter. These data suggest that ISQ is correlated to IT and is influenced mainly by implant diameter and not by implant length, location or bone level. Finally, a case including immediate implants, bone augmentation and immediate provisional restoration is presented.

Immediate loading in the maxilla using flapless surgery, implants placed in predetermined positions, and prefabricated provisional restorations: a retrospective 3-year clinical study.

BACKGROUND: Immediate loading of dental implants shortens the treatment time and makes it possible to give the patient an esthetic appearance during the whole treatment period. PURPOSE: The aim of the present study was to evaluate an immediate-loading treatment protocol, which included flapless surgery, implants placed in predetermined positions and connected to prefabricated provisional restorations, and the 3-year clinical results. MATERIALS AND METHODS: A total of 97 Brånemark System Mk IV implants (Nobel Biocare AB, Gothenburg, Sweden) with a machined surface were inserted in the maxillas of 46 patients. A presurgical three-dimensional model of the patients' soft tissue and underlying alveolar bone anatomy was created, which allowed the clinician to place the implants in predetermined positions and connect them to prefabricated provisional restorations. A surgical template with drilling guides corresponding to each implant was used. The apical part of the master guide was equipped with a circular "mucotome," which punched out a 5 mm hole in the mucosa to eliminate the need for flap elevation. The patients received 25 fixed partial prostheses and 27 single-tooth restorations. Bone quality and quantity were assessed. Radiographic examinations were performed on the day of surgery/loading and at the 1-, 2-, and 3-year follow-up visits. RESULTS: All implant sites showed intact buccal and lingual bone walls during surgery, confirming the accuracy of the bone-mapping procedure. The prefabricated temporary restorations fitted, meaning that the implants were positioned clinically in the same way as on the cast. Nine implants in eight patients failed during the first 8 weeks of loading. This resulted in a cumulative survival rate of 91% after 3 years of prosthetic load. The survival rate of splinted implants was 94%. The number of failed implants was significantly higher in cases of single-tooth replacements and placement in soft bone sites and smokers. The failed implants were successfully replaced according to a two-stage protocol. All patients finally received the expected restoration. The marginal bone resorption was on average 1.0 mm during the first year of loading, 0.4 mm during the second year, and 0.1 mm during the third year. CONCLUSIONS: The study confirmed the feasibility of an immediate-loading treatment protocol in the maxilla, which included flapless surgery, implants and abutments placed in predetermined positions, and prefabricated provisional restorations. All failures occurred within the first 2 months of loading. The unchanged survival rate and the low average bone loss found during the following 34-month study period indicate a good long-term prognosis for the performed immediate-loading treatment.

Immediate loading of titanium plasma-sprayed screw-shaped implants in man: a clinical and histological report of two cases.

THIS STUDY REPORTS ON THE histological findings of two immediately loaded titanium plasma-sprayed (TPS) implants, retrieved for a fracture of the abutment and for psychological reasons, after 8 and 9 months of loading, respectively. The microscopical analysis showed that mature, compact, cortical bone was present around both implants, with the bone implant contact percentage about 60 to 70%. No fibrous tissue or gaps were present at the interface. No resorption was present in the peri-implant bone. On both implants a few osteoblasts were found positive at the interface for alkaline phosphatase (ALP); while no cells positive for acid phosphatase (ACP) were present. Immediate loading can, perhaps, be used in very selected cases of good bone quality, with implants that have certain macro- (screw shape) and micro-interlocks (titanium plasma-sprayed surface) characteristics. Good results have been reported also for non-TPS surface (e.g., machined surface). More data about different designs (e.g., cylinders) or coatings (e.g., hydroxyapatite) are needed before any firm conclusions about immediate loading can be reached.

Surgical and prosthetic concepts for predictable immediate loading of oral implants.

Immediate loading of oral implants is an established concept for lower jaw restoration using four intraforaminal implants splinted together with a bar. There is a lot of misunderstanding in the literature and not exact definition of the term "immediate loading." Moreover, the number of implants to restore edentulous jaws is relatively high to compensate for the loading forces and dependent on the bone quality and quantity. This report presents the different surgical and prosthetic concepts for immediate loading to get long-term success in the upper and lower jaw. When the primary stability is adequate, only six implants may be loaded immediately after surgery, if the implants are splinted using a provisional fixed restoration. Using a number of six primary stable implants, it is possible to restore edentulous jaws independent on the clinical situation. This concept may be used successfully in the posterior part of the mandible when three implants are splinted with provisional crowns and loaded immediately. The biomechanical aspects, the implant design and surface seem to be of great importance for the long-term success in compromised and advanced surgical cases. In conclusion, immediate loading of oral implants may be successful if a primary stability as well as immobilization (splinting) immediately after surgery are taken care.

Immediate restoration of multiple tooth implants for aesthetic implant restorations.

The immediate restoration or loading of dental implants has been an intense area of clinical trial and research in the field of dental implantology over the last several years. The ability to temporize implants that are placed and prevent the use of a removable transitional appliance is appealing to not only patients, but dentists as well. Additionally, the placement of implants into immediate extraction sockets, and the immediate restoration of those implants, is showing excellent success rates clinically. Enhancement of the healing phase using platelet rich plasma seems to be a key contributor to the healing and maturation rate of both the hard and soft tissues. This article will review the immediate restoration of implants placed into multiple extraction sockets and the use of platelet rich plasma to enhance the healing phase.

Clinical outcome of implants placed immediately after implant removal.

BACKGROUND: The purpose of this study was to evaluate the clinical success of implants placed immediately after the explantation of failed implants due to fracture at 12 months. METHODS: Nine immediate implants were placed in nine patients following explantation of nine fractured implants. Five experimental implants did not require any regenerative procedures; the remaining four immediate implants were grafted with deproteinized porcine bone particles and covered with bioabsorbable membranes. All implants were restored with fixed prostheses. The follow-up period was 12 months. RESULTS: No residual bone defects were observed or probed around any implant at the second-stage surgery, and all implants were asymptomatic and stable. All the implants were successful after prosthetic rehabilitation showing no mobility, pain, suppuration, or absence of peri-implant radiolucency. The radiographic measurements showed no significant bone loss pattern at the 12-month follow-up visit. CONCLUSION: The findings of this study suggested that implants placed immediately after implant explantation due to biomechanical fracture could be performed with results that are similar to results obtained with implants placed immediately after tooth extraction.

Immediate implant placement: a case series.

A major drawback of implant therapy is the comparatively long healing period involved. Early and immediate loading of dental implants can significantly decrease the treatment time and thus result in an increase in patients' comfort. In this report, 3 cases of placement and immediate loading of the final implants are presented. In 2 of these cases, where preliminary augmentation was necessary, provisional implants were placed after the procedure and immediate provisional dentures were delivered. With the exception of 1 case, in which 1 implant failed, no adverse events were observed. All cases are in function now for 3 to 5 years after implant placement. The observations from this limited number of cases confirm that immediate loading of implants could be a viable treatment option.

[The use of new biologically compatible materials in the combined treatment of periodontal diseases].

The authors analyze various orthodontic constructions used in multiple-modality treatment of periodontal diseases. Special attention is paid to combinations of direct fitting with prostheses and use of the novel osteoinductive and immunomodulating agents. Nineteen patients with periodontal diseases were treated. Removable splints, prosthetic splints, and other devices were employed. Special emphasis is made on the use of biositall M-31-a composition on the basis of hydroxyapatite and Algigel. All these materials were found to be effective at the stage of surgical treatment of periodontal diseases, particularly so in combination with immediate prostheses and sodium alginate-based therapeutic films.
