*** Months post-restoration at time of failure

Table 5 – Patient’s Results By Stage Achieved

	Number of
Stage	Patients	Implants	Successful Implants	Failed Implants
Surgery	34	227	—-	—-
Exposed, Failure	6*	13	0	13
Exposed, Successful, Not Attached	5	38	38	0
Attachment completed	29	176	175	1

* One patient had failed implants at exposure and other implants were successful at uncovering.
