“All‐on‐Four” Immediate‐Function Concept with Brånemark System® Implants for Completely Edentulous Mandibles: A Retrospective Clinical Study ABSTRACT Background: Immediate‐function Brånemark System® implants (Nobel Biocare AB, Gothenburg, Sweden) have become an accepted alternative for fixed restorations in edentulous mandibles, based on documented high success rates. Continuous development is ongoing to find simple protocols for their use. Purpose: The purpose of this study was to develop and document a simple, safe, and effective surgical and prosthetic protocol for immediate function (within 2 hours) of four Brånemark System implants supporting fixed prostheses in completely edentulous mandibles: the “All‐on‐Four” concept. Materials and Methods: This retrospective clinical study included 44 patients with 176 immediately loaded implants, placed in the anterior region, supporting fixed complete‐arch mandibular prostheses in acrylic. In addition to the immediately loaded implants, 24 of the 44 patients had 62 rescue implants not incorporated in the provisional prostheses but incorporated in final prostheses later on. Results: Five immediately loaded implants were lost in five patients before the 6‐month follow‐up, giving cumulative survival rates of 96.7 and 98.2% for development and routine groups, respectively. The prostheses' survival was 100%, and the average bone resorption was low. Conclusions: The high cumulative implant and prostheses survival rates indicate that the “All‐on‐Four” immediate‐function concept with Brånemark System implants used in completely edentulous mandibles is a viable concept.

Tilted Implants for the Rehabilitation of Edentulous Jaws: A Systematic Review ABSTRACT Purpose: The aim of this review was to evaluate the survival rate of upright and tilted implants supporting fixed prosthetic reconstructions for the immediate rehabilitation of partially and fully edentulous jaws, after at least 1 year of function.Materials and Methods: An electronic search of databases plus a hand search on the most relevant journals up to December 2009 was performed. The articles were selected using specific inclusion criteria, independent of the study design.Results: The literature search yielded 347 articles. A first screening based on the title and abstract identified 25 eligible studies. After full‐text review of these studies, 10 articles were selected for analysis. Seven were prospective single‐cohort studies and three had a retrospective design. A total of 462 patients have been rehabilitated with 470 immediately loaded prostheses (257 in the maxilla, 213 in the mandible), supported by a total of 1,992 implants (1,026 upright and 966 tilted). Twenty‐five implants (1.25%) failed in 20 patients within the first year. All failures except one occurred in the maxilla. No significant difference in failure rate was found between tilted and upright implants, nor between maxillary and mandibular implants. No prosthesis failure was reported. Limited peri‐implant bone loss was reported with no difference between upright and tilted implants. Full patients' satisfaction for function, phonetics, and esthetics was reported in three studies, based on questionnaires.Conclusions: The use of tilted implants to support immediately loaded fixed prostheses for the rehabilitation of edentulous jaws can be considered a predictable technique, with an excellent prognosis in the short‐medium term. However, randomized long‐term trials are needed to determine the efficacy of this surgical approach.

Biomechanical behavior of titanium and zirconia frameworks for implant‐supported full‐arch fixed dental prosthesis Abstract Background The biomechanical behavior of implant‐supported titanium and zirconia full‐arch fixed dental prosthesis (FAFDP) frameworks require further investigation. Purpose Strains transferred by implant‐supported titanium (Ti) and zirconia (Zr) FAFDP frameworks were analyzed. Materials and Methods Maxillary 14‐unit FAFDPs supported by 6 implants and 12‐unit FAFDPs supported by 4 implants were tested. One‐piece frameworks were fabricated by computer‐aided design/computer‐aided manufacturing. Four groups were divided (n = 3): G1, Ti‐6 implants; G2, Zr‐6 implants; G3, Ti‐4 implants; G4, Zr‐4 implants. A 250 N single‐point load was applied on the second premolar. A three‐dimensional digital image correlation system recorded framework and maxilla model surface deformation. Results The following strains (μS) averaged over the length of the second premolar were calculated: frameworks, G1 (321.82 ± 111.29), G2 (638.87 ± 108.64), G3 (377.77 ± 28.64), G4 (434.18 ± 132.21); model surface, G1 (473.99 ± 48.69), G2 (653.93 ± 45.26), G3 (1082.50 ± 71.14), G4 (1218.26 ± 230.37). Zirconia frameworks supported by 6 implants (G2) presented higher surface strains (P < .05). FAFDPs with titanium frameworks transferred significantly lower strains to the supporting maxilla when 6 implants were used (G1) (P < .05). Both framework materials transferred similar strains when supported by 4 implants (G3 and G4) (P > .05). Conclusions Zirconia frameworks supported by 6 implants showed higher strains. FAFDPs supported by 6 implants transferred less strains to the supporting maxilla, irrespective of framework material.

“All‐on‐4” Immediate‐Function Concept for Completely Edentulous Maxillae: A Clinical Report on the Medium (3 Years) and Long‐Term (5 Years) Outcomes ABSTRACT 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 report on the medium‐ and long‐term outcomes of a protocol for immediate function 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 242 patients with 968 immediately loaded implants (Brånemark System® TiUnite™, Nobelspeedy™, 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 months, 1 year, and thereafter every 6 months. Radiographic assessment of the marginal bone level was performed after 3 and 5 years in function. Survival was estimated at patient level and implant level using the Kaplan–Meier product limit estimation with 95% confidence intervals.Results: Nineteen immediately loaded implants were lost in seventeen patients, giving a 5‐year survival rate estimation of 93% and 98% at patient and implant level, respectively. The survival rate of the prosthesis was 100%. The marginal bone level was, on average, 1.52 mm (standard deviation [SD] 0.3 mm) and 1.95 mm (SD 0.4 mm) from the implant/abutment junction after 3 and 5 years, respectively.Conclusion: The high survival rates at patient and implant level indicates that the immediate‐function concept for completely edentulous maxillae using the present protocol is viable in the medium‐ and long‐term outcomes.

Evaluation of “All‐on‐Four” Concept and Alternative Designs with 3D Finite Element Analysis Method Abstract Purpose The aim of the present study was to evaluate the effect of the forces on the implant and supporting alveolar ridge in “all on four” concept and alternative designs using finite element analysis. Materials and Methods Different treatment alternatives with various implant designs were performed in an edentulous mandible. In Design 1, implants were placed according to “All‐on‐Four” concept; Design 2, two long (13 mm long, 4 mm diameter) and two short (7 mm long, 4 mm diameter) implants; Design 3, four long and two short implants; and Design 4, two long and four short implants were placed vertically. A force of 100 N for each tooth, a total of 300 N load was applied. Finite element analysis was used to evaluate and compare the different designs. Results The stress concentration within the cortical bone was significantly higher than the trabecular bone around the neck of the implants. The maximum stress values were located around the cortical bone of the distal implant for all designs. The reduction in the number of implants did not diminish the success of the design. Conclusions In the presence of vertically resorbed posterior mandibula, although the “all on four” concept is a feasible approach clinically, short implants had decreased the amount of force transmitted to the supporting bone.

<scp>A</scp>ll‐on‐4® Treatment Concept for the Rehabilitation of the Completely Edentulous Mandible: A 7‐Year Clinical and 5‐Year Radiographic Retrospective Case Series with Risk Assessment for Implant Failure and Marginal Bone Level Abstract Background Studies are needed to evaluate long‐term outcomes of the A ll‐on‐4® treatment concept (N obel B iocare AB ) for rehabilitation of edentulous mandibles by assessing marginal bone levels and risk indicators for implant failure. Purpose To evaluate 7‐year clinical outcomes and 5‐year radiographic outcomes of the A ll‐on‐4 treatment concept. Materials and Methods This retrospective case series included patients admitted for implant rehabilitations in the mandible, who were followed for 7 years clinically and 5 years radiographically. Primary outcome measures were cumulative prosthetic and implant survival using patient as the unit of analysis (K aplan‐M eier product limit estimator). Secondary outcome measure was marginal bone level (MBL ) at 5 years. Variables associated with implant failure were analyzed using the C ox proportional hazards regression model to calculate hazard ratios (HRs ) with 95% confidence intervals (CIs ). Binary logistic regression was used to compute odds ratio (OR ) with 95% CIs for variables associated with MBL ≥2.8 mm at 5 years. Results A total of 324 patients (194 women, 130 men, average age = 58.9 years) were rehabilitated with 1,296 implants supporting 324 full‐arch fixed immediately loaded mandibular prostheses. Sixty‐four patients (19.8%) were lost to follow‐up. Prosthetic survival was 323/324 (99.7%), and 14 patients lost 18 implants, with an estimated cumulative survival rate of 95.4% at 7 years. Variables associated with implant failure were smoking (HR = 5.28; 95% CI: 1.33, 20.91]) and the learning curve effect (0.69 < HR < 0.33 for more experienced levels). Mean MBL at 5 years was 1.81 mm (95% CI : 1.70, 1.92), and smoking was associated with MBL ≥2.8 mm (OR = 2.4; 95% CI: 1.02, 5.62). Conclusions The high implant and prosthetic survival rates and excellent MBL outcome confirm the predictability and safety of the A ll‐on‐4 treatment concept over a longer term than previously reported.

An Interdisciplinary Treatment Approach Combining Orthodontic Forced Eruption with Immediate Implant Placement to Achieve a Satisfactory Treatment Outcome: A Case Report ABSTRACT Background: Periodontal disease often results in severely bony defects around the teeth and leads to eventual extraction. Remaining bone morphology often compromises ideally restoration‐driven positions and deteriorates the success rates for dental implants.Purpose: The present investigation illustrates the clinical outcome of immediately installing an implant following orthodontic forced eruption and atraumatic extraction.Material and Methods: The subject of this study is a 40‐year‐old Asian female with a right mandibular first molar that had a deep probing depth on the mesial side and mobility. Via the aid of radiographic examination, the tooth that had an angular bony defect and apical lesion was diagnosed as having deep caries and chronic periodontitis with a poor prognosis. After consultation with the patient, we developed a treatment plan incorporating a forced eruption with immediate implantation, intended to augment the alveolar bone volume and increase the width of keratinized gingivae, in a nonsurgical manner.Results: Following 12 months of orthodontic treatment, the tooth was successfully moved occlusally in conjunction with an 8 mm vertical interdental bone augmentation. Because of sufficient volume of bone and satisfactory gingival dimensions, the implant showed adequate initial stability in the correct position to facilitate physiological and aesthetic prerequisites. After 6 months of ossteointegration, a customized impression coping was utilized to transfer the established emergence profile to a definitive cast for the fabrication of a customized abutment. The final prosthesis was made using a customized metal abutment and ceramometal crown.Conclusion: In the face of difficult clinical challenges, meticulous inspection and a comprehensive treatment plan were crucial. Interdisciplinary treatment through the careful integration of multiple specialists suggests the possibility of optimal results with high predictability.
