_Abstract A clinical study of various types of Hi-Tec Im- plants (Herzlia, Israel)—uncoated titanium thread implants & push-in cylinder implants, coated with either TPS or hydroxyapatite (HA) surfaces, used by a surgical team in various sur- gical procedures. The purpose of the study was tofindwhetherthedesignorcoatingofimplants has any effect on the success rate and integra- tion of the implant in different procedures. The study did not indicate any statistical signifi- cance in the success rate of the different im- plants in the different types of procedures: sim- ple implantology, sinus lift procedures, bone augmentation and immediate extraction sites. _Introduction Variousimplantdesignsandimplantcoatings are in wide use and success rates are of the var- ious designs and surfaces are well documented Success rate comparison between HA coated and non coated threaded implants1, 2 as well as comparisonbetweenHAandTPScoatedcylinder implants have been documented.3 Use of im- plants varies in different procedures, and com- parisons between the success rate in different procedures including placing implants immedi- ately in to fresh extraction sits is documented4, 5, 6 as well as success rate in different locations.7 The objective of the study was to present the success rate of fixtures of different designs and surfaces used in complex implant procedures, implants placed in internal sinus lift procedures (Figs. 1a–b), implants placed in lateral sinus lift procedures (Figs. 2a–b) bone augmentations, implants placed including grafting of buccal defect (Figs. 3a–d), and implants placed simulta- neously with teeth extractions (Figs. 4a–d), all performed by one team. The retrospective study was conducted on pa- tients treated at the Maxillary Facial Dept. of the Meir Hospital, Kfar Saba Israel, and comprised of 144 implants consequently placed over a period of 4yearsin44patientswithpartialorcompleteeden- 28 I I study _ design and surfaces Fig. 1a_Alveolar bone height 1mm to sinus, before extracting second premolar.
