Methods: Candidates for this study were consecutive patients who presented with one or more missing or unsalvageable teeth in a private dental practice in years 2003-2005. 13 patients received 49 one piece implants (Q-implant) which were placed and loaded in a one stage procedure, 11 patients received 24 one-piece implants (Q – implant) which were immediately placed with non-submerged healing and delayed loading, 10 patients received 39 two piece implants ( Q-implant) which were placed and loaded in a one stage procedure.Radiographic evaluation was performed; Marginal Bone Loss (MBL) around implants was analyzed.
Results: During the observation period there was more MBL in one- piece implants compared to two piece implants. There was no statistical significant difference in MBL between immediate or delayed loaded one piece implants. Nevertheless it seems that immediate loaded implants show more MBL. MBL around mandibular implants was lower than around maxillary implants.
Conclusions: Within the limits this study, it is concluded that with the use of one piece implants the clinician can predictably restore missing maxillary and mandibular dentition.
