Astra Tech presents new OsseoSpeed Studies

Astra Tech presented three new studies of its OsseoSpeed Implants at the Astra Tech World Congress held in held in Gothenburg, Sweden.

Study 1: Five-year clinical evidence for early loading of OsseoSpeed implants

In a recently published prospective study by H. Schliephake et al. ¹, the 5-year clinical outcome from 44 patients treated with 123 implants placed in the posterior mandible and early loaded, was presented. All implants survived the whole study period giving a 100% implant survival rate. Implant stability, by means of ISQ values, increased during the first year and the marginal bone level change was minimal ending in a total mean change from implant placement to 5-year of -0.08 mm. The authors concluded that implants with the fluoride-modified OsseoSpeedTM surface provide auspicious results for the early loading protocol in the posterior mandible.

Study 2: Evaluation of OsseoSpeed 3 mm narrow implant
A prospective multicenter study by P. King et al.², included 69 patients, together treated with a total of 97 implants. The OsseoSpeedTM narrow implants were replacing a single tooth in the anterior region and the study was designed to evaluate clinical performance using one stage surgery with an early loading protocol. Two-year follow up indicates that treatment with OsseoSpeedTM TX 3.0 implants is a safe and predictable treatment option in the anterior region when interdental space is limited. Soft tissue and marginal bone levels were well preserved.

Study 3: Marginal bone support around OsseoSpeed Profile implants
In a prospective multicenter study by R. Nölken et al.³, 65 patients with a need of single tooth replacements were included. The aim of the study was to clinically and radiographically evaluate the position of lingual, buccal and interproximal marginal bone support after placing and restoring a single OsseoSpeedTM Profile implant in sloped healed ridges. After 1 year, the results revealed small marginal bone level alterations indicating that the OsseoSpeedTM Profile implant is a predictable treatment option where the alveolar crest anatomy is sloped in a lingual to buccal direction.

Regarding the stories, Astra Tech commented:

“We are very proud to present continuous positive data from our global clinical research program at the Astra Tech World Congress. For us it is of utmost importance that clinicians feel confident when using our implant system to care for their patients. Ninety percent of all dental implant systems available today have no clinical documentation.” says AnnaKarin Lundgren, Head of Global Scientific Management.
