研究概览
简要总结
The aim of the study is to test in a randomized comparative study the performance of Straumann® MembraGel (PEG Membrane) to act as a barrier for guided bone regeneration compared to that of a standard collagen membrane (BioGide®) in the bone regeneration around Straumann® SLActive bone level titanium implants.
Furthermore the clinical evaluation and comparison of complementary parameters describing the bony and soft tissue environments at the surgical sites during the study period to evaluate effectiveness and performance of the membranes.
详细描述
At the primary endpoint of the study - 6 month post-operative - the vertical bone gain will be measured for changes.
The changes will be evaluated by measuring the distance between the implant shoulder and the first visible bone contact on the implant. The measurement will be taken on the medial and distal aspect on the implant at site of interest. Measurements will take into account distortion based on changes on the radiograph from the true dimension of the implant.
Intra-oral photographs will be taken at each study visit to document the initial appearance of the soft tissue and the subsequent healing of the soft tissue post-implant placement. The photographs will be taken buccal and occlusial at study site of interest.
The physical appearance of soft tissue (form, colour, tissue biotype, surface aspect) will be clinically assessed by visual inspection.
In addition changes in the high of the keratinized gingiva will be assessed in mm. This will be measured mid-crestal in buccal direction to the mucogingival border by a periodontal probe.

入选标准
- •Subjects must have voluntarily signed the informed consent form before any study related action
- •Males and females must be at least 18 years of age and not more than 80 year old.
- •Have at least one missing tooth in the posterior mandible or maxilla in quadrant 1, 2, 3, 4 (FDI positions 4-7), requiring one or more dental implants.
- •Partially edentulous patients and patients in need of a fixed dental prosthesis
- •The tooth at the implant site(s) must have been extracted or lost at least 6 weeks before the date of implantation.
- •Bone defect(s) must be present with a vertical dimension greater than or equal to 3 mm at the foreseen GBR site measured after dental implant placement.
- •Full mouth bleeding on Probing (FMBoP) and full mouth plaque score (FMPI) are both lower or equal than 25%
- •Patients must be committed to the study.
排除标准
- •Presence of conditions requiring chronic routine prophylactic use of antibiotics (e.g., history of rheumatic heart disease, bacterial endocarditis, cardiac valvular anomalies, prosthetic joint replacements)
- •Major systemic diseases
- •Medical conditions requiring prolonged use of steroids
- •Use of Bisphosphonate intravenously
- •Current pregnancy or breastfeeding women
- •Physical or mental handicaps that would interfere with the ability to perform adequate oral hygiene
- •Alcoholism or chronically drug abuse
- •Immunocompromised patients
- •Patients who smoke more than 10 cigarettes per day or cigar equivalents, or who chew tobacco
- •Conditions or circumstances, in the opinion of the investigator, which would prevent completion of study participation or interfere with analysis of study results, such as history of non-compliance, or unreliability.
- •Local exclusion criteria
- •Local inflammation, including untreated periodontitis
- •Regenerative treatment necessary adjacent to the planned study site of interest
- •Mucosal diseases or oral lesions
- •History of local irradiation therapy
- •Severe bruxing or clenching habits
- •Persistent intraoral infection
- •Patients with inadequate oral hygiene or unmotivated for adequate home care
- •Previous GBR or GTR treatment at the implant site
- •Lack of primary stability of the dental implant at site of interest. In this instance the patient must be withdrawn and the patient treated accordingly (exclusion criteria at surgery)
