    Input: 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 This paper describes the 5-year results of a comparative study between Astra Tech and Brånemark system implants . The aim was to compare the systems primarily with regard to bone level changes , and also with regard to other variables of interest . Sixty-six patients with edentulous jaws were included in the study . R and omisation schedules were used to allocate the patients to the two implant systems . 184 Astra Tech implants with a titanium-blasted surface and 187 Brånemark implants with a turned surface were used . The implants were inserted with a two-stage technique and the insertion followed the routines for the respective implant system . All patients were provided with full-arch fixed bridges . All patients were followed up with clinical and radiographic examinations from fixture insertion to the 5-year follow-up . The total mean bone level change in the upper jaw between fixture insertion and the 5-year examination was -1.74+/-0.45 mm at the Astra implants and -1.98+/-0.21 at the Brånemark implants . The corresponding values for the lower jaw were -1.06+/-0.19 for Astra and -1.38+/-0.17 for Brånemark . The major postoperative changes of the marginal bone level took place between fixture insertion and baseline . During this period , there was also a different pattern of bone remodelling between the implant systems . Between baseline ( prosthesis connection ) and the 5-year examination , the marginal bone level changes were small , with no difference between the implant systems . The implant stability was examined with the supraconstructions removed . At the 5-year examination , the survival rate for Astra Tech implants was 98.4 % and for the Brånemark implants it was 94.6 % . The difference was not statistically significant The aim of this study was to determine the influence of age on peri-implant tissues in patients treated with implant-supported overdentures in the m and ible . A prospect i ve study was carried out with 2 groups of healthy edentulous patients . The mean age of the younger group ( n = 32 ) was 46 years ( range 35 to 50 years ) ; the mean age of the older group ( n = 26 ) was 68 years ( range 60 to 80 years ) .  Two dental implants were placed in the interforaminal region of the m and ible , and after a 3-month healing period , overdentures were fabricated . Clinical and radiographic parameters were evaluated immediately after completion of the prosthetic treatment , after 1 year , and after 3 years . The evaluated clinical parameters were implant loss , Plaque Index , Gingival Index , Bleeding Index , and probing depth . Radiographic evaluation was performed using a st and ardized long-cone technique with a direction device . Statistical analysis was carried out with SPSS software . One implant in the older group was lost during the healing period . After 3 years , the mean scores for Plaque Index , Gingival Index , and Bleeding Index were between 0 and 1 for both groups ( out of possible scores of 0 to 3 ) , and the mean probing depth was 3 mm in both groups . The mean bone loss after 3 years was 1.2 mm in the younger group and 0.8 mm in the older group , but this difference was not significant . It was concluded from this study population that the clinical performance of implant-supported overdentures in the m and ible is equally successful in younger and older patients This report is an up date on a group of 46 clinical trial patients who each received 3 free-st and ing Endopore dental implants placed using a 2-stage surgical approach in the anterior m and ible . After an initial healing interval of 10 weeks , the implants were used in each case to retain an over-denture , and at the time of the report , all patients had passed 5 years of continuous function . The 5-year cumulative " survival " rate based on a life table analysis was 93.4 % and this remained unchanged after 6 years . The 5-year " success rate " was 83.3 % when assessed qualitatively with the published criteria of others using a four-field table analysis categorizing every implant in the study as one of " Grade 1 Success " , " survival " , " unaccounted for " or " failure " . Modified periodontal parameters verified continued peri-implant soft tissue health . No implant still in function had more than 1.8 mm cumulative bone loss during the first 5 years of function . These results provide clear evidence that Endopore implants despite their short lengths function at least as well as other dental implant design s used in much longer lengths PURPOSE This r and omized controlled clinical trial aim ed to evaluate the efficacy of splinted implants versus unsplinted implants in overdenture therapy over a 10-year period . MATERIAL S AND METHODS The study sample comprised 36 completely edentulous patients , 17 men and 19 women ( mean age 63.7 years ) . In each patient , 2 implants ( Brånemark System , Nobel Biocare , Göteborg , Sweden ) were placed in the interforaminal area . Three to 5 months after placement , they were connected to st and ard abutments . The patients were then rehabilitated with ball-retained overdentures , magnet-retained overdentures , or bar-retained overdentures ( the control group ) . Patients were followed for 4 , 12 , 60 , and 120 months post-abutment connection . Group means as well as linear regression models were fitted with attachment type and time as classification variables and corrected for simultaneous testing ( Tukey ) . RESULTS After 10 years , 9 patients had died and 1 was severely ill . Over 10 years , no implants failed . Mean Plaque Index , Bleeding Index , change in attachment level , Periotest values , and marginal bone level at the end of the follow-up period were not significantly different among the groups . DISCUSSION The annual marginal bone loss , excluding the first months of remodeling , was comparable with that found around healthy natural teeth . CONCLUSION The fact that no implants failed and that overall marginal bone loss after the first year of bone remodeling was limited suggested that implants in a 2-implant m and ibular overdenture concept have an excellent prognosis in this patient population , irrespective of the attachment system used Osseointegrated implants as anchors for various prosthetic reconstructions have become a predictable treatment alternative . It was expected that implants required submucosal placement during the healing period for successful tissue integration . However , it has been demonstrated that healing and long-term health of implants could be achieved with equal predictability in a 1-stage , non-submerged approach . This prospect i ve 5-year study not only calculates implant success by life table analysis , but also evaluates the correlation between observed bone level changes with clinical parameters as measured by suppuration , plaque indices , bleeding indices , probing depth , attachment level and mobility . A total of 112 ITI dental implants were inserted in different areas of the jaws .  Clinical and radiographic parameters were evaluated annually for 5 years , whereas a portion of the study group for which 6-year evaluations were available were included in the life-table analysis . The overall success rate after 5 years in service was 99.1 % , while after 6 years it was reduced to 95.5 % due to the fracture of 3 implants in 1 patient . The mean crestal bone loss experienced during the first year was 0.6 mm followed by an annual yearly loss of approximately 0.05 mm . No significant differences could be found between the amount of bone loss measured at each of the yearly follow-up visits . This suggests that statistically the followed implants did not show any radiographically measurable bone loss following the initial period of bone loss associated with implant placement and osseointegration . Low levels of correlation between the individual and cumulative clinical parameters with radiographically measured bone loss suggests that these parameters are of limited clinical value in assessing and predicting future peri-implant bone loss The aim of this prospect i ve r and omized controlled clinical trial was to evaluate and compare clinical aspects and satisfaction during the first year following treatment and consecutively the change in treatment during the next 4 years of follow-up . Patients were allocated to one of the following treatment modalities : an implant-retained overdenture ( IRO-group , 2 endosseous implants , n = 61 ) or  a complete denture ( CD-group , n = 60 ) . One year after placement of the denture , unsatisfied patients of the CD-group got the opportunity for a retreatment including an implant-retained overdenture . In the IRO-group 4 implants were lost during the first year and again 4 implants were lost during the next 4 years ( survival rate : 93 % ) . All patients could be re-operated successfully . In the CD-group 14 patients ( 23 % ) chose an implant-retained overdenture after 1 year . Patients of the IRO-group were significantly more satisfied than patients of the CD-group after 1 year ( satisfaction score 8.3 versus 6.6 , scale 1 - 10 ) and after 5 years ( 7.4 versus 6.4 ) . From this study it can be concluded that endosseous implants have a high survival rate after 5-years ' follow-up . Satisfaction score of the IRO-group is diminishing in time , probably because patients get used to an improved situation . After 5 years , the mean satisfaction score of the CD-group ( including patients who got implants ) was still lower than of the IRO-group , in spite of the opportunity to a retreatment and have implant-retained overdentures OBJECTIVE The purpose of this prospect i ve study was to evaluate one-stage dental implants clinical ly and radiographically after 10 years in function . MATERIAL AND METHODS Twenty-five patients with a total of 68 implants [ 46 hollow screws ( HS ) and 22 hollow cylinders ( HC ) ] who previously participated in 5-year prospect i ve clinical study returned for a 10-year follow-up . For each patient , informed consent was obtained , medical and dental history was review ed and soft and hard tissue conditions were evaluated using the modified plaque index , modified sulcus bleeding index , probing depth , suppuration , attachment level , distance from the implant crown margin to the coronal border of the peri-implant mucosa keratinized mucosa and periapical radiographs to calculate crestal bone-level changes . RESULTS As expected , the mean crestal bone-level changes were the greatest in the first year following restoration placement , while only minimal changes were noticed in the subsequent years . HC implants showed a statistically significant higher mean crestal bone loss when compared with HS implants at year 10 . Gender was also statistically significantly related to the mean crestal bone loss at years 1 , 3 , 5 and 10 , with male subjects exhibiting more bone loss than female subjects . However , age and peri-implant soft tissue parameters showed low levels of correlation with the mean crestal bone-level changes , and proved to be weak predictors for the mean crestal bone loss at years 5 and 10 . CONCLUSIONS This study confirms that the mean crestal bone loss rates of the HS and HC implants are well within the clinical ly acceptable parameters . In addition , some of the clinical parameters could be used to assess and predict future crestal bone loss BACKGROUND Dental implants with moderately rough surfaces are commonly used in the treatment of edentulous patients . However , long-term data on survival rates and marginal bone conditions are lacking . PURPOSE This prospect i ve study evaluated the cumulative survival rate of the TiOblast implant ( Astra Tech AB , Mölndal , Sweden ) after 10 years of prosthetic loading . MATERIAL S AND METHODS A total of 199 TiOblast implants were placed in 36 consecutive edentulous patients ( 23 males and 13 females ) . All patients were treated at one clinic and by the same team . The patients were edentulous in either the maxilla ( n = 16 ) or the m and ible ( n = 20 ) . The average age of the patients at the start of the trial was 64 years ( range , 59 - 82 years ) . Of the 199 
    Output:
    
FES harboured more plaque at their implants than PES .
Modified bleeding index scores were significantly higher in FES , but no differences in bleeding on probing , implant loss and probing pocket depth were observed between FES and PES .
CONCLUSION FES and PES show comparable implant survival rates .
However , no conclusion can be drawn regarding differences in prevalence of peri-implant mucositis and peri-implantitis between FES and PES
