Treatment notes

This patient suffers from a severe case of Guillain-Barré syndrome and has great difficulty using his forearms and hands. He presented with a subgingival fracture of no. 10, deemed to be unrestorable (figures 1 and 2). In a discussion of a bridge versus an implant, the patient desired a single-tooth replacement given his challenge in maintenance.
The decision to use the Ditron Implant System was based on the need for extraction and immediate implant placement, with immediate provisionalization using a final titanium abutment. The Ditron Ultimate implant gives a very secure initial stability and strong abutment connection to address the need for compression of treatment time.At the initial surgical appointment, the left maxillary lateral incisor was removed, the osteotomy carefully debrided, and a Ditron Ultimate implant was placed to the ideal placement protocols (figures 3 and 4). The implant provided such favorable initial stability that I was able to place the final abutment and prepare it intraorally for the provisional restoration.
A final titanium solid abutment was placed (figure 5) and torqued to recommended values. The abutment was then prepared intraorally and a composite resin provisional placed out of function in all excursions.
The implant was allowed to heal for two months before impressions. The final zirconia crown was delivered two weeks later (figure 6).


The patient related to our office that he had absolutely no postoperative discomfort, no prosthesis complications, and was very impressed by the entire experience as he had a different outcome for his previous implant tooth replacements.
