Recession [ Time Frame: every 12 months for 3 years ] [ Designated as safety issue: No ]
The Astra Tech 3.0 mm 2 piece implant can be placed and restored in a 5 mm or greater bone space for a mandibular incisor or maxillary lateral incisor site (minimum 5 mm mesio-distal [side to side] bone width and 5mm bucco-lingual [front to back] bone width) without exhibiting recession of the soft tissue (gingival margin or the interproximal papillae).

Aesthetic evaluation of two piece 3mm implants for single tooth replacement of maxillary laterals and mandibular incisors

PURPOSE OF THE STUDY:

The purpose of this research study is to examine the aesthetics (the appearance of the implanted tooth and gums) as well as the soft tissue loss over a three-year period. This study involves replacing a missing small front tooth with a dental implant, abutment, and crown. A titanium dental implant acts as the replacement for a tooth root. An abutment is made of titanium which is either gold or silver in color and cannot be seen; but may affect the way the gum looks. An abutment is the component that attaches the crown to the implant post. A crown (which acts as the tooth replacement) is made of metal and/or porcelain and attaches over the abutment.

The dental implant and the abutments used in this study have been approved by Health Canada and the U.S. Food and Drug Administration (FDA) for the use of replacing the small teeth in the front of the mouth.

The abutment is made in two colors (either gold or silver) and you cannot choose. For each subject this is decided by chance. You will have an equal chance of getting a gold or silver-colored attachment. You will know which color the abutment will be once you have consented to be in the study and registered. You will know the color of the abutment before the implant is placed. The abutment is covered by the crown.

You will be in this study for about three years. There will be approximately 60 subjects who will participate in this study in different centres, in Canada and the USA.

Probability Sample

Subjects for this study will be recruited from the practices of the six study centers (Dr. Caudry + 5 centers from the North American PEERS group) within a period of eighteen months from commencement of the study. A total of sixty subjects (ten per center) of any gender and race aged 18 and older will be accepted provided they meet the inclusion and exclusion criteria (see page 6). Dental implants for permanent tooth replacement are not indicated for use in those under the age of 18. Vulnerable subjects will not be included.

Inclusion Criteria:

  • Capacity to provide written informed consent to participate in the study.
  • 18 years or older

Site requirements:

A minimum of premolar occlusion is required. A minimum mesio-distal and buccal-lingual distance of 5mm is required

Exclusion Criteria:

  • Rampant caries or unstable periodontal disease of the remaining dentition.
  • Any systemic or local disease or condition that may compromise post-operative healing.
