The purpose of this study is to compare three different dental implants.  To participate, volunteers must be 18 years of age, in good health and desire a tooth implant to replace a single tooth missing in their upper jaw.  No tooth implants will be placed in molar sites.

Volunteers in need of at least one dental implant in the front region of their upper jaw will be recruited for a research study.

All implants are made of titanium, a metal that has been successfully used in dental implants for more than 30 years. 

The study products and the study dentist’s visits, study procedures and laboratory tests will be provided at no cost.  Neither the subjects nor your insurance company will be charged for the costs.  Your other expenses in connection with the study, such as travel, parking and lodging, will not be reimbursed.

Volunteers must meet all inclusion criteria and none of the exclusion criteria.

Study Title: Case series evaluation of a short dental implant placed in the posterior maxilla in an early loading protocol. 

This research study will evaluate and document the clinical effectiveness of an FDA cleared  dental implant in the treatment of subjects missing teeth in their posterior upper jaw.  A minimum of two but preferably three dental implants shall be considered for each subject.  The dental implants will be placed in the posterior upper jaw and allowed to heal for six weeks prior to a provisional/temporary dental bridge being attached to the implants.  The permanent dental bridge will be attached to the implants approximately 1 year after the dental implant surgery.  The research study is a five-year follow up study and requires 14 clinic visits.  Seven (7) of these clinic appointments occur in the first 12 months of subject participation.  Additional clinical follow-up appointments for analyses will be performed at 1, 2, 3, 4 and 5 years after placement of the provisional/temporary dental bridge.  

Cost to participate:

There are costs for being in this research study.  The costs are for the charges for the dental surgeon who performs the dental implant surgery.  Subjects will have a choice of either a College of Dentistry faculty or resident to perform the surgery. The residents are dentists who are receiving specialized training in either Oral Surgery or Periodontics.

If you choose a College of Dentistry Faculty Dentist, the costs are as follows:

For two implants = $4,650.00  For three implants = $6,600.00

 If you choose a College of Dentistry Resident Dentist, the costs are as follows:

For two implants = $3,860.00  For three implants = $5,435.00 

Volunteers must meet all inclusion criteria and none of the exclusion criteria.
