•*Be able to communicate effectively with study personnel,
•&Have a missing tooth on each side of the one jaw in the antero lateral segments,
•*Have adequate bone levels (judged by radiographic assessment) to afford an implant based therapy to replace these missing teeth, and
•*Be keen and motivated to have these missing teeth replaced.

•Exclusion criteria
•*Any disease or condition which might compromise the haematopoietic, renal, endocrine, pulmonary, central nervous, cardiovascular, immunological, dermatological, gastrointestinal or any other body system.

•*Ridge deficiencies that warrant bone augmentation procedure either at or prior to implant placement. The minimum ridge dimension of 7mm width as measured by a ridge caliper or using a cone beam CT scan will be applied as a preliminary criteria. ( Should the subject need an augmentation for implants to be placed and should he/ she meet no other exclusion criteria but meet all inclusion criteria , he/ she can be reassessed for inclusion 6 months after an augmentation procedure ( at patients cost ) ).
