    Input: To comprehend the results of a r and omised controlled trial ( RCT ) , readers must underst and its design , conduct , analysis , and interpretation . That goal can be achieved only through total transparency from authors . Despite several decades of educational efforts , the reporting of RCTs needs improvement . Investigators and editors developed the original CONSORT ( Consoli date d St and ards of Reporting Trials ) statement to help authors improve reporting by use of a checklist and flow diagram . The revised CONSORT statement presented here incorporates new evidence and addresses some criticisms of the original statement . The checklist items pertain to the content of the Title , Abstract , Introduction , Methods , Results , and Discussion . The revised checklist includes 22 items selected because empirical evidence indicates that not reporting this information is associated with biased estimates of treatment effect , or because the information is essential to judge the reliability or relevance of the findings . We intended the flow diagram to depict the passage of participants through an RCT . The revised flow diagram depicts information from four stages of a trial ( enrolment , intervention allocation , follow- up , and analysis ) . The diagram explicitly shows the number of participants , for each intervention group , included in the primary data analysis . Inclusion of these numbers allows the reader to judge whether the authors have done an intention- to-treat analysis . In sum , the CONSORT statement is intended to improve the reporting of an RCT , enabling readers to underst and a trial 's conduct and to assess the validity of its results PURPOSE To compare the outcome of immediately loaded  single implants  inserted with medium ( from 25 to 35 Ncm ) or high insertion torques ( > 80 Ncm ) . MATERIAL S AND METHODS Fifty patients received two single non-adjacent implants  , each r and omly inserted flapless with a torque between 25 to 35 Ncm or > 80 Ncm according to a split-mouth design . Non-occluding temporary crowns were immediately placed on provisional abutments and definitive crowns were delivered after 6 weeks . Patients were followed for 6 months after initial loading . Outcome measures were crown/implant failures , complications , peri-implant marginal bone level changes , postoperative pain and presence of peri-implant apical radiolucency . RESULTS No drop-out occurred . Seven implants inserted with a torque between 25 to 35 Ncm failed versus none of the implants inserted with a torque > 35 Ncm . With the exception of crown/implant failures ( exact McNemar significance P = 0.0156 , difference in proportions : -0.12 ; 95 % CI -0.21 to -0.02 ) there were no statistically significant differences between groups for the other outcome measures . CONCLUSIONS It is preferable to insert single implants with a high insertion torque ( > 80 Ncm ) , to minimise early implant failures , when loading them immediately OBJECTIVES The aim of the present split-mouth study is to assess the peri-implant conditions around early-loaded s and blasted and acid-etched ( SLA ) implants , 5 years after abutment connection and to compare , in the same patients , the results obtained with a st and ard protocol using identical implants with a TPS surface . MATERIAL AND METHODS Surgical procedure was performed by the same operator and was identical at test ( SLA ) and control ( TPS ) sites , in 32 healthy patients . Abutment connection was carried out at 35 N cm 6 weeks postsurgery for test sites and 12 weeks for the controls . Patients were seen regularly , for control and professional cleaning . At 60 months , clinical measures and radiographic bone changes were recorded by the same operator , blind to the type of surface of the implant , on 27 patients , as five patients were lost to follow-up . RESULTS A total number of 106 implants were examined . No implant was lost . No significant differences were found with respect to the presence of plaque [ modified plaque index ( mPI ) 0.27+/-0.56 vs. 0.32+/-0.54 ] , bleeding on probing ( 29 % vs. 32 % ) , mean pocket depth ( 3.2+/-1 vs. 3.2+/-1 mm ) or mean marginal bone loss ( 0.32+/-1.04 vs. 0.44+/-1.12 mm ) between test and control . Four implants that presented ' spinning ' at the time of abutment connection presented no significant differences from the rest of the test sites . CONCLUSION The results of this prospect i ve study confirm that SLA implants , under defined conditions , are suitable for early loading at 6 weeks in both the m and ible and the maxilla . Limited implant spinning , occasionally found at abutment connection , produces no detrimental effect on the clinical outcome when properly h and led PURPOSE To compare the efficacy of immediate functionally loaded implants placed with a flapless procedure ( test group ) versus implants placed after flap elevation and conventional load-free healing ( control group ) in partially edentulous patients . MATERIAL S AND METHODS Forty patients were r and omized : 20 to the flapless immediately loaded group and 20 to the conventional group . To be immediately loaded , implants had to be inserted with a minimum torque > 45 Ncm . Implants in the immediately loaded group were provided with full acrylic resin temporary restorations the same day . Implants in the conventional group were submerged ( anterior region ) or left unsubmerged ( posterior region ) and were left load-free for 3 months ( m and ibles ) or 4 months ( maxillae ) . Provisional restorations were replaced with definitive single metal-ceramic crowns 1 month postloading . Outcome measures were prosthesis and implant failures , biological and prosthetic complications , postoperative edema , pain , and use of analgesics . Independent sample chi2 tests , Mann-Whitney tests , t tests , and paired t tests were used with a significance level of .05 . RESULTS Fifty-two implants were placed in the flapless group and 56 in the conventionally loaded group . In the flapless group , 1 flap had to be raised to control the direction of the bur and 1 implant did not reach the planned primary stability and was treated as belonging to the conventional group . After 3 years no dropouts or failures occurred . There was no statistically significant difference for complications ; however , patients in the conventional group had significantly more postoperative edema and pain and consumed more analgesics than those in the flapless group . Osstell values were significantly higher at baseline in the flapless group ( P = .033 ) . When comparing baseline data with years 1 , 2 , and 3 within each group , mean Osstell values of the flapless group did not increase , whereas there were statistically significant increases in the Periotest values . CONCLUSIONS Implants can be successfully placed flapless and loaded immediately without compromising success rates ; the procedure decreases treatment time and patient discomfort Purpose : The aim of this study was to evaluate and compare immediate-loaded implant-retained m and ibular overdentures  and delayed-loaded implant-retained m and ibular overdentures .  Material s : Ten completely edentulous male patients received 40 dental implants .  Patients were r and omly divided into 2 equal groups , 5 patients each . Patients of both groups received conventional maxillary complete denture and had stage 1 surgery for placing 4 dental implant fixtures , 2 on each side anterior to the mental foramina . Group A : One-stage surgical procedure and immediate loading . Patients in this group received m and ibular bar-retained overdenture supported by 4 endosseous implants loaded immediately after implant placement . Group B : The original 2-stage concept and delayed loading . Patients in this group received m and ibular bar-retained overdenture supported by 4 endosseous implants that remained submerged for a period of 4 months before loading . The patients were evaluated clinical ly and radiographically immediately after overdenture delivery and after 6 months , 12 months , 18 months , and 24 months . Results : The results of clinical evaluation showed no statistical significant difference between the 2 groups regarding the effect of treatment . The radiographic assessment showed no statistical significant difference in mesial and distal alveolar bone loss at the different intervals of the follow-up period , except at the 12-month period , where immediately loaded implants showed a decrease in the amount of alveolar bone loss mesially and distally compared to delayed loaded implants . Conclusions : The results suggest that immediate-loaded implants provide promising results compared to delayed-loaded implants and can be a possible alternative procedure in implant dentistry This study was design ed to compare the results of immediate and delayed loading of implants with implant-retained m and ibular overdentures . Ten patients ( test group ) received 40 Brånemark System MKII implants ( 4 per patient ) placed in the interforaminal area of the m and ible . St and ard abutments were immediately screwed to the implants , rigidly connected with a bar , and immediately loaded with an overdenture . Ten patients ( control group ) received the same type and number of implants in the same area , but the implants were left to heal submerged . Four to 8 months later , st and ard abutments were screwed to the implants and the same prosthetic procedure was applied . Each implant was evaluated at the time of prosthetic loading and at 6 , 12 , and 24 months after the initial prosthetic load with the following parameters : modified Plaque Index ( MPI ) , modified Bleeding Index ( MBI ) , probing depth ( PD ) , and Periotest . Peri-implant bone resorption was evaluated on panoramic radiographs taken 12 and 24 months after initial prosthetic loading . No significant differences were found between the 2 groups regarding MPI , MBI , Periotest , peri-implant bone resorption , and PD at 6 and 24 months ( P > .05 ) . The only difference was found regarding PD values on the mesial and lingual sites at 12 months ( P < .05 ) . The cumulative success rate of implants was 97.5 % in both groups . Results from this study showed that immediate loading of endosseous implants rigidly connected with a U-shaped bar does not seem to have any detrimental effect on osseointegration . Conversely , this method significantly shortens the duration of treatment with relevant satisfaction for the patients OBJECTIVES The aim of the present study was to evaluate the outcome of immediate functional loading of implants in single-tooth replacement using two different installation procedures . MATERIAL AND METHODS One hundred and fifty-one subjects , who required single-tooth rehabilitation in the area of 15 - 25 and 35 - 45 , were enrolled in eight private clinics in Italy . The implant sites were r and omly allocated to one of the following treatment groups . In the control group , in which a st and ard preparation procedure for implant placement and submerged healing of the implant was used , abutment connection and loading of the implants were performed 3 months after installation . In the test group 1 , a st and ard preparation procedure for the implant placement and immediate functional loading of implant was carried out . In the test 2 group , however , a modified implant installation procedure ( osteotome technique ) was used followed by immediate functional loading of the implant . Clinical and radiographic examinations were performed at 3 and 12 months of follow-up at all sites . RESULTS Three implants ( 5.5 % ) from the test 2 group ( osteotome preparation ) and one ( 2 % ) from the test 1 group ( conventional drill preparation ) failed to integrate and were removed one and three months after implant installation . The mean marginal bone loss assessed at 12 months was 0.31 mm ( test 1 ) , 0.25 mm ( test 2 ) and 0.38 mm ( control ) ( no statistically significant differences were found between the three treatment groups . ) CONCLUSION It is suggested that immediate functional loading of implants that are placed with a conventional installation technique and with sufficient primary stability may be considered as a valid treatment alternative in a single-tooth replacement PURPOSE The primary goal of this stratified r and omized controlled trial ( S RCT ) was to compare the stability of  dental implants  placed under three different loading regimens during the first 16 weeks of healing following implant placement . Implants were loaded immediately , early ( 6 weeks ) , or with conventional/delayed timing ( 12 weeks ) . Secondary outcomes were to compare marginal bone adaptation for 3 years after placement . MATERIAL S AND METHODS Single posterior implant sites in the maxilla or m and ible were examined . The insertion torque value was the primary determinant of load assignment . Resonance frequency analysis was performed at follow-up appointments for the first 16 weeks ( with results provided as implant stability quotients [ ISQs ] ) . Marginal bone levels were assessed via radiographs . RESULTS Forty patients each received a single 4.0-mm diameter dental implant between 2004 and 2007 . One implant failure occurred in Lekholm and Zarb type 4 bone with insertion torque value ( ITV ) of < 8.1 Ncm ; the cumulative success rate was 97.5 % . All implants , when classified by bone and loading type , increased in stability over time , with a minor reduction of 1.3 ISQ units seen at 4 weeks in the immediate loading group . The mean marginal bone loss over 3 years was 0.22 mm . The mean ITVs at implant placement for bone types 1 and 2 ( grouped together ) , 3 , and 4 were 32 , 17 , and 10 , respectively , and were significantly different ( P < .05 ) . CONCLUSIONS ITV was a good objective measure of bone type . Using an ITV of 20 Ncm as the determinant for immediate loading and an ITV of 10 Ncm or greater as the determinant for early loading provided long-term success for this implant and led to no negative changes in tissue response . All bone type groups and loading groups showed no reduction in stability during the first 4 months of healing OBJECTIVES The aim of this clinical study was to determine the effectiveness of progressive loading procedures on preserving crestal bone height and improving peri-implant bone density around 
    Output:
    
Overall there was no convincing evidence of a clinical ly important difference in prosthesis failure , implant failure , or bone loss associated with different loading times of implants .
