Effect of dental implant surface roughness on guiding osteoblasts chemotaxis and osseointegration: Clinical application of Straumann implant system

Abstract

BACKGROUND: As a new-type and effective restoration means of dentition defect and edentulous, implant denture is a restoration method most closely related to natural teeth, and is accepted by more and more patients. OBJECTIVE: To investigate the clinical effects of non-submerged dental implants with sandblasted and acid-etched surface preparation (Straumann implants system). METHODS: Patients who visited Oral Implantology Center of the Affiliated Hospital of Qingdao University Medical College from June 2007 to June 2009 were selected as study subjects. Systemic and local contraindications were excluded. A total of 124 patients who had 218 Straumann implants implanted were followed up for 3 to 24 months. According to various patients' conditions, conventional approach, immediately implanted, GBR technique and flapless operation were adopted respectively. Clinical effects were evaluated with the Albrektsson's criteria. RESULTS AND CONCLUSION: There was no implant loosen, shedding or X-ray transmission in 218 implants. Both the survival rate and successful rate of implants were 100%. High degree of satisfaction from patients was achieved. Straumann implants system could be considered as a manageable and satisfactory non-submerged implant system.
