CLINICAL TRIAL REGARDING THE SIZE OF THE IMPLANTS INSERTED IMMEDIATELY OR DELAYED USING EXTERNAL SINUS LIFTING TECHNIQUES
Abstract:
Introduction: Inserting the implants in the upper jaw posterior area remains a challenge for
any implantologist when the bone offer is poor, a difficult approach, near anatomical structures and the
risk of perforating the sinusal membrane. Many prosthetic techniques have been tested in case of bone
atrophy, by protecting the sinusal area, but the most optimal intervention on the sinus remains
separating the sinusal membrane and augmentation. Materials and methods: This retrospective study is
part of a bigger project which aims the osseointegration of S-Line implants in Osteon allografts, taking
place for a period of 1 year in the Oral Implantology Clinic within the Military Hospital of Sibiu in
partnership with the manufacturing company. Results and discussions: This study included implants that
were prosthetically loaded with metal-ceramics reconstructions always secured and not including
adjacent natural teeth. Selected patients were not exposed to other alveolar ridge augmentation
techniques; the width of the ridge was above 5 mm. For all the patients in the study we have inserted
implants for every missing tooth in the upper jaw lateral area, providing a safe mechanical support.
Subcortical clogging technique was not used to avoid aspiration of the implant in the sinus.
Conclusions: In the limits of this study the data has argued that beta-tricalcium phosphate of Osteon in
sinus lifting is a secure material, predictable, with no signs of adverse reactions and no invasive.
