The Early Loading of Different Surface Modified Implants: A Prospective Clinical Study

Abstract

The early loading of different surface treated dental implants is compared in our clinical study. Patients were selected from the outpatient ward of the Department of Oro-Maxillofacial Surgery and Stomatology at the Semmelweis University. The secondary stability, that evolved after 6 weeks of healing, was measured on acid etched/sand blasted (SLA) and bio-hydroxyapatite coated implants. Osstell® and Periotest® were applied to determine this value. Periodontal probing depth appearing after 3 months of loading was checked on 6 points next to the implant supported prosthesis. Shapiro-Wilk and Mann-Whitney tests have been chosen to fulfil the statistical analysis. According to our results, a similar satisfying secondary stability can be obtained independently of the modality of the surface. The values were higher in the bio-hydroxyapatite group; however, this difference was not significant. The outcome of measuring the probing depth reflects the importance of frequent recalls of patients. The necessary ethical approval for our study has been provided by the National Institute of Pharmacy and Nutrition (reference number: OGYÉI/55197/2019 ).
