Scientific Literature 2. Boerrigter et al Oral RehabiI1997 Controlled clinical trial (60 patients), comparing the effect of mandibular overdentures on two different implant systems “Brånemark system and the IMZ-system” in edentulous patients were compared one year after insertion of the new dentures. Evaluation included peri-implant and radiographical parameters . During the osseointegration period, five Brånemark and one IMZ-implants were lost. The results were less favorable for the Brånemark group than for the IMZ-group; however, these differences were not significant .

Scientific Literature ,[object Object],Geertman et al Data of 2 different RCTs were combined. No separate data. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],Boerrigter et al Number of enrolled patients unclear. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],Jones et al Study not classified as a RCT. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],Karlsson et al Not all patients were participating in a split Mouth study. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],Geurs et al Unclear which implant type(s) failed. Number of dropouts also unclear. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],Mau et al Unusual high dropout rate (only data of 189 of the 313 patients admitted in the trial were presented). Dropouts often classified as such for questionable reasons. Early failures counted as dropouts. Esposito et al lnt J Oral Maxillofac Implants 2005

Scientific Literature ,[object Object],. 1. Meijer et al J Clin Periodontol 2004 prospective comparative study was to evaluate the survival rate and the condition of the peri-implant tissues of the IMZ implant system (two-stage cylindertype), the Brånemark implant system (two-stage screwtype) and the ITI implant system (one-stage screwtype) supporting a mandibular overdenture during a 5-year follow-up period. After 5 years no clinically relevant and statistically significant radiographic changes had developed between the three implant systems.

Scientific Literature . 2. Engquist et al . Clin Oral Implants Res 2002 Follow up for Astrand et al 1999 which demonstrated high survival rates and small marginal bone changes for Astra Tech when compared with Brånemark System implants. Result : There was no significant marginal bone change between baseline and the 1-year examination or between the 1- and 3-year examinations. The survival rate of Astra Tech implants was significantly higher (98.9%) than for Brånemark System implants

Scientific Literature 3. Astrand et al Clin Oral Implants Res 2004 Follow up for Astrand et al 1999 which demonstrated high survival rates and small marginal bone changes for Astra Tech when compared with Brånemark System implants. Result : Between baseline and the 5-year examination, the marginal bone level changes were small, with no difference between the implant systems. 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.

Comparative Analysis of Various Dental Implant Systems ,[object Object],Astra versus Branemark Implants Astrand et al compared submerged Astra screw-type implants and submerged Branemark screw-type implants using a parallel group design in totally edentulous patients. Thirty-three fully edentulous patients (17 maxillae and 16 mandibles)

Comparative Analysis of Various Dental Implant Systems ,[object Object],Considering the patient as the unit for the analysis, there was no statistically significant difference between the implant systems in regard to either failure or marginal bone level change after 5 years of function.

Comparative Analysis of Various Dental Implant Systems ,[object Object],Branemark versus IMZ Implants . Batenburg et al compared 2 submerged Branemark implants used to support mandibular overdentures with 2 IMZ submerged implants used to support mandibular overdentures using a parallel group design. Thirty patients were included in each group.

Comparative Analysis of Various Dental Implant Systems ,[object Object],Branemark versus ITI Implants . Batenburg et al compared 2 submerged Branemark MKII screw-type implants used to support mandibular overdentures with 2 ITI TPS hollow screw-type implants used to support mandibular overdentures.Thirty patients were included in each group .

Comparative Analysis of Various Dental Implant Systems ,[object Object],IMZ versus ITI Implants Batenburg et al compared 2 submerged IMZ TPS cylinders supporting mandibular overdentures with 2 nonsubmerged ITI TPS hollow screws Supporting mandibular overdentures on parallel group design. Thirty patients were included in each group.

Comparative Analysis of Various Dental Implant Systems ,[object Object],Southern versus Steri-Oss Implants Tawse-Smith et al in Two trials with a parallel group design compared the use of 2 nonsubmerged, unsplinted Southern implants to support an Overdenture with the use of 2 nonsubmerged, unsplinted Steri-Oss screws. The design of the 2 trials was identical, except that in 1 trial the implants were conventionally loaded at 12 weeks, whereas in the other, the implants were loaded early, at 6 weeks.

Comparative Analysis of Various Dental Implant Systems ,[object Object],Meta-analyses were done of the 2 above studies. Considering the patient as the unit for the analysis, there were no statistically significant differences in regard to failures and marginal bone level changes between the implant systems after 5 years of function.

Comparative Analysis of Various Dental Implant Systems ,[object Object],A meta-analysis comparing early implant failures between various implants with turned and roughened surfaces .Two trials were included “ Astrand et al & Batenburg et al “

Comparative Analysis of Various Dental Implant Systems ,[object Object],Considering the patient as the unit for the analysis, no statistically significant differences were observed between the implants with turned surfaces and those with roughened surfaces in regard to number of early failures .

Comparative Analysis of Various Dental Implant Systems ,[object Object],Only 1 trial “Astrand et al “ was available that compared the occurrence of peri-implantitis between various implants with turned and roughened surfaces at 5 years. .
