Immediate placement and immediate provisionalization of ITI implants in maxillary non-restorable single teeth. A prelimenary report.
J Pak Dent Assoc Jan ;13(2):66-71.

OBJECTIVE: This prospective study was conducted to examine the outcome of Sandblasted Large Grit Acid Etched (SLA) surface, solid screw implants placed immediately into extraction sockets and loaded within one hour of implant placement to achieve immediate replacement of non-restorable single maxillary teeth. PATIENTS & METHODS: Thirty-five ITI implants in thirty-one patients were placed and immediately restored with a non-occluding provisional acrylic crown. Porcelain fused to metal crowns were cemented six weeks later. RESULTS: All 35 implants achieved osseointegration as demonstrated by stability and function at the placement of the final un-splinted crown. The healing process was uneventful and without adverse events. There were no reported peri-implant mucosal complications. The prosthetic procedures occurred without intervening incident of abutment loosening or fracture. DISCUSSION: Considerable advantages exist to immediate placement and provisiolanization after tooth extraction, soft tissue profiles can remain stable and alveolar bone loss can be avoided. The rationale for replacing maxillary molars is debatable. CONCLUSIONS: Immediate placement of ITI dental implants following tooth extractions and immediately provisionalized is a viable treatment option.

USER COMMENTS

More detailed criteria for evaluation of results are required. Osseointegration is a histological phenomenon and can be only cofrimed hisologically. However stability in itself is a clinical finding. One can claim the implants to be stable but not to be osseointegrated. Stability in itself is examined by torque resistence, mobility, perimplant mucosal health etc. Furthermore, what was the follow up post loading evaluation period. The claim of implants being success at the time of loading is not valid. Further, the mentioning of rationale for replacing maxillary molars being debatable is indeed a separate topic and indeed highly debatable. Although the success rate of posterior maxillary implants are slightly less then those of mandibular, high success have been documented in 10 year followup trials. More over, immediate implants have been placed and documented for many many years. The conclusion has been implemented in practises already for many years.
