Brief Summary
Dental implants are small metal posts that look like miniature screws. They are surgically implanted into the jawbone where they serve as substitute tooth roots. Implants are used in dentistry to reestablish function and aesthetics to areas of the mouth were natural teeth are missing. Classical dental implants are made in two pieces. One part anchors in the jawbone and one part serves as a connecting post (an abutment) that attaches to a crown restoration or to attachment clasps that hold a denture in place. Occasionally the materials used to fasten the two implant components together work their way loose and over time the abutment may begin to disconnect. If this happens a small gap appears between the implant and abutment. There are many reasons why this loosening occurs. One reason may be the design of the implant itself and another may be the way the two components are fastened together. This study will assess the performance of an implant with a new design. The investigators hypothesize that using this implant design will reduce the risk of an implant-abutment disconnect and improve long-term success of implant therapy.

Interventions
Subjects in this study receive ACE CONNECT Internal-Connection dental implants to: 1)replace a missing tooth in an edentulous area of the maxilla or mandible restored with a single-unit crown (may include up to two non-adjacent areas as study sites) or, 2)subjects with an edentulous mandible will receive two implants placed in the lower canine position and restored with an implant-retained removable over-denture. Subjects will return for four follow-up evaluations scheduled at 6, 12, 18 and 24 months after delivery of the permanent restoration.
Eligibility Criteria
Dental school periodontology clinic
You may qualify if:
- Need for replacement of non-adjacent missing teeth with dental implants
- Edentulous in the area for more than 2 months
- Minimum native bone height and width to receive a 10mm X 4mm implant
You may not qualify if:
- Untreated decay or periodontal disease in residual dentition
- Need for bone or soft-tissue augmentation in the proposed implant site
- Pregnancy
- Consistent use of medications likely to compromise bone healing
- Chronic disease condition likely to compromise bone healing
- Consistent smoking over 10 cigarettes during the immediate past 6 months
