Straumann Roxolid Multi-Center Study

Completed · Not applicable

Conditions studied: Jaw, Edentulous, Partially

In brief

The primary objective of this study is to demonstrate non-inferiority of the Straumann Bone Level Ø 3.3 mm NC SLActive Roxolid Implants compared to Straumann Bone Level Ø 4.1 mm RC SLActive Roxolid Implants based on mean crestal bone level changes measured between surgery and 12 months post-implant placement. The secondary objectives will assess differences in clinical outcomes between the test and control implants, including implant success and survival, gingival recession, subject satisfaction and additional early bone level measurements.

Who can join

Age: 20 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Subjects must have voluntarily signed the informed consent form
• Subjects must be males or females who are a minimum of 20 years of age
• Subjects must have a single tooth gap in the pre-molar or anterior region of the mandible or maxilla (ADA tooth positions 4-13 and 20-29; FDI tooth positions 11-15, 21-25, 31-35, and 41-45)
• Subjects must have opposing dentition (natural teeth, fixed or removable restorations)
• Subjects must have a full mouth plaque score ≤ 25%, according to O'Leary, at the time of screening
• Subjects must have adequate bone to encapsulate the implant and allow placement of an Ø 4.1 mm Bone Level Implant.
• Adequate bone height of at least 1 mm longer than the length of the study implant
• Subjects must have substantially healed (at least 16 weeks after tooth extraction) extraction sockets
• Subjects must be committed to the study and the required follow-up visits
• Subjects must be in good general health as assessed by the Investigator

You may not qualify if…

• Subjects with a systemic disease that would preclude dental implant surgery (e.g. serious internal medical problems, disorders of bone metabolism, uncontrolled bleeding disorders, weakened immune system, illness requiring periodic use of steroids, uncontrollable endocrine disorders, uncontrolled diabetes)
• Subjects with any contraindications for oral surgical procedures (e.g. inadequate wound healing capacity, poor oral hygiene, maxillary and mandibular growth not completed, xerostomia)
• Subjects with mucosal diseases (e.g., erosive lichen planus) in the localized area around the study implant site
• Subjects with a history of local irradiation therapy in the head/neck area
• Subjects with any untreated endodontic lesions or untreated periodontal disease adjacent to the implant site
• Subjects receiving, or having a history of receiving, intravenous or subcutaneous antiresorptive agents, such as bisphosphonates
• Subjects with severe bruxing, parafunctional habits, or temporomandibular joint dysfunction
• Subjects with existing implants in the adjacent positions to the planned implant site
• Subjects requiring bone augmentation or socket grafting within 6 months prior to surgery
• Subjects requiring more than minimal simultaneous augmentation for minimal buccal dehiscence defects (defect cannot be greater than 3mm in height)
• Subjects with inadequate oral hygiene or who are unmotivated for adequate home care
• Subjects who have physical or mental handicaps that would interfere with the ability to perform adequate oral hygiene
• Subjects who are pregnant or intending to become pregnant during the duration of the study
• Subjects who are heavy smokers (defined as >10 cigarettes per day or >1 cigar per day) or chew tobacco
• Subjects who abuse alcohol or drugs
• Subjects who have undergone administration of any investigational device within 30 days of enrollment in the study
• Subjects with 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
