Evaluation of single‐tooth restorations on ITI dental implants. A prospective study of 29 patients

Abstract

From January 1992 to March 1997, a total of 30 ITI hollow cylinder implants were installed to replace lost single maxillary incisor teeth. Conical abutments with cemented all-ceramic crowns were used in 10 cases and the Octa-abutment with screw-retained metallo-ceramic crowns in 19 cases. One implant failed due to postoperative infection, and was extracted a month after installation. After a mean observation time of 3.4 years, the cumulative success rate is 96.7%. Only minor bone loss has occurred around the implants, and there have been no other complications to date. The implant system fulfills the requirements for good function and esthetics.

Brånemark System® and ITI Dental Implant System® for treatment of mandibular edentulism

“…The Periotest was applied on top of the Octa‐abutment, which was nearer the bone level than the application point, the edge of the abutment, of the BRS group. A supraosseous leverage effect, due to the mechanical properties of the supraosseous implant components, has previously been proposed in explanation (Olivé & Aparicio 1990; Teerlinck et al 1991; Moberg et al 1999). To what extent differences in Periotest values reflect changes in bone anchorage of the implants is still unresolved (Aparicio 1997; Salonen et al 1997).…”

A paralleling technique modification to determine the bone crest level around dental implants

“…When evaluating peri-implant changes, other authors have pointed out that radiographic evaluation of peri-implant bone level cannot be more than a precision of 0.5 mm when parallelism is not guaranteed and the distance focus-object is under 380 mm. 4 For Moberg et al, 16 the radiographic precision in measuring the distance between the crown and alveolar bone was approximately 0.2 mm, implying a random error of up to 0.4 mm for a registration with a 95% probability. In our results, the precision with method 1 was 0.08 mm and with method 2 it was 0.13 mm.…”

Role of mechanical environment and implant design on bone tissue differentiation: current knowledge and future contexts

“…60 So far, the clinical outcome studies, even for single-tooth ITI w implant replacements indicate high survival rates that slightly decline after 5 -10 years. 3,63,64 From a biomechanical perspective, the implant-abutment junction should have such a design that reduces the peak bone-implant interface shear stresses and strains. According to Hansson, the junction should be located at a cervico-occlusal level not close to the region the implant starts to contact bone.…”
